BUFFALO, NY – February 14, 2025 – A new #review was #published in Oncotarget, Volume 16, on February 12, 2025, titled “SETDB1 amplification in osteosarcomas: Insights from its role in healthy tissues and other cancer types.” Authors Elodie Verdier, Nathalie Gaspar, Maria Eugenia Marques Da Costa, and Antonin Marchais from the Gustave Roussy Cancer Campus analyzed recent studies on a gene called SETDB1, which may play a key role in osteosarcoma, a type of bone cancer that mostly affects teenagers and young adults. Their review highlights how SETDB1 helps cancer cells grow, resist treatment, and avoid the immune system. Because of this, blocking SETDB1 could be a promising new way to treat osteosarcoma. Osteosarcoma is a fast-growing bone cancer that is usually treated with surgery and chemotherapy. However, if the cancer spreads or returns, treatment options are very limited. Scientists are searching for new ways to stop this disease, and recent studies have found that osteosarcoma cells often have extra copies of the SETDB1 gene. This seems to make the cancer more aggressive and harder to treat. “Whole exome sequencing of osteosarcoma samples from both diagnosis and relapses has highlighted several factors, including SETDB1, that are amplified in the most aggressive forms of the disease.” SETDB1 is involved in epigenetics, meaning it affects how genes are turned on and off without changing the DNA itself. The review explains that SETDB1 helps tumors hide from the immune system, making it difficult for the body to fight the cancer naturally. The researchers believe that blocking SETDB1 could help the immune system recognize and attack osteosarcoma cells. Some experimental drugs that target SETDB1 are already being tested in the lab. The review also describes how SETDB1 influences key cancer pathways, such as Wnt signaling, which helps cancer cells grow, and epithelial-mesenchymal transition (EMT), a process that allows cancer to spread. The authors suggest that combining SETDB1-blocking drugs with immunotherapy or radiation could be an effective new strategy for treating osteosarcoma. Another key finding is that SETDB1 may help cancer cells become resistant to chemotherapy, making treatment less effective. This means that drugs targeting SETDB1 could not only slow cancer growth but also make existing treatments work better. While more research is needed, this review brings attention to SETDB1 as a potential treatment target. Scientists hope that a deeper understanding of SETDB1 will lead to new therapies that improve survival rates for osteosarcoma patients.

For years, breast cancer has been classified as either HER2-positive or HER2-negative, determining whether a patient could receive HER2-targeted therapies like trastuzumab (Herceptin). However, a growing body of research suggests a middle category—HER2-low breast cancer—which has led to important changes in how clinicians approach treatment. A recent review published in Oncotarget, titled “Evolving Concepts in HER2-Low Breast Cancer: Genomic Insights, Definitions, and Treatment Paradigms,” explores what this means for both patients and clinicians​.

BUFFALO, NY - February 10, 2025 – A new #casereport was #published in Volume 16 of Oncotarget on February 5, 2025, titled “A case report of donor cell–derived hematologic neoplasms 9 years after allogeneic hematopoietic cell transplantation." In this case report, Aleksandra Mroczkowska-Bękarciak and Tomasz Wróbel from Wroclaw Medical University describe a rare and serious complication after a stem cell transplant. The case involves a patient who, nine years after receiving a stem cell transplant for acute myeloid leukemia (AML), developed a new, aggressive blood cancer originating from donor cells. Despite receiving treatment, the disease progressed to myelodysplastic syndrome/acute myeloid leukemia (MDS/AML), ultimately leading to the patient’s death. Stem cell transplants are a life-saving treatment for many blood cancers, including AML. While relapse of the original cancer is the most common concern, this case highlights another rare but serious complication: the development of donor cell-derived hematologic neoplasms (DCHN). The report details the case of a 23-year-old woman who remained in remission for nearly 10 years following a successful hematopoietic stem cell transplant from an unrelated donor. However, she later developed a new form of leukemia, driven by genetic mutations in the ASXL1, SETBP1, and EZH2 genes—biomarkers linked to highly aggressive blood cancers. Over the next two years, the disease progressed despite intensive treatment, ultimately proving fatal. This case highlights the need for continued monitoring of transplant recipients, even years after the procedure. Although DCHN is extremely rare, its occurrence raises critical questions about the process by which donor cells transform into leukemia. Some stem cell donors may unknowingly carry genetic mutations that are harmless in their own bodies but could trigger cancer in recipients. Additionally, factors such as immunosuppressive therapy, bone marrow stress, and transplantation procedures may contribute to these rare but deadly outcomes. “Early diagnosis and intervention are crucial to improving patient prognosis.” Ongoing research is focused on improving donor screening methods to help predict and prevent these complications. In the future, routine genetic testing for stem cell donors could become a standard part of the transplant process, helping clinicians identify potential risks before transplantation. More studies are needed to fully understand why donor-derived cancers develop and how they can be prevented. With continued progress in precision medicine and genetic diagnostics, researchers aim to make stem cell transplants safer and more effective for all patients.

BUFFALO, NY - February 6, 2025 – A new #casereport was #published in Volume 16 of Oncotarget on February 5, 2025, titled “Acquired RUFY1-RET rearrangement as a mechanism of resistance to lorlatinib in a patient with CD74-ROS1 rearranged non-small cell lung cancer: A case report." In this case report, Jenny L. Wu from Vanderbilt University School of Medicine and Wade T. Iams from Vanderbilt-Ingram Cancer Center describe a rare case of drug resistance in a patient with advanced non-small cell lung cancer (NSCLC). The patient, a 42-year-old man who had never smoked, initially responded well to lorlatinib, a targeted therapy designed to treat cancer driven by specific genetic alterations. However, after six months, his cancer began to grow again. Clinicians discovered that this was due to a new genetic change, known as the RUFY1-RET fusion. This finding highlights how cancers can adapt to treatment and the importance of ongoing genetic testing to guide therapy decisions. NSCLC is the most common type of lung cancer, and in some cases, it is driven by genetic changes that can be targeted with specific drugs. The patient’s cancer originally had a ROS1 gene rearrangement, which made it responsive to lorlatinib. But as time went on, the cancer started to grow again, and tests revealed a new genetic alteration called RUFY1-RET fusion, which likely caused resistance to lorlatinib. This new genetic change was identified using RNA next-generation sequencing (RNA NGS), an advanced test that can find mutations that standard genetic tests might miss. After discovering the RUFY1-RET gene fusion, the patient was treated with a combination of lorlatinib and pralsetinib, a drug that specifically targets RET gene alterations. While this combination helped control the cancer for about four months, the patient’s condition unfortunately worsened after four months. “This is the first reported case of a RET fusion as a potential mechanism of resistance to lorlatinib, it identifies a novel RET fusion partner, and it emphasizes the importance of testing for acquired resistance mutations with both DNA and RNA at the time of progression in patients with targetable oncogenic drivers.” Understanding cases like this can help clinicians and researchers develop more effective treatment strategies, including combination therapies that target multiple genetic changes to combat drug resistance. While the combined therapy in this case provided only temporary benefits, it offers important insights for future research and patient care, particularly for cancers that no longer respond to standard treatments.

An unexpected link between KLRG1 and PD-1, two key immune system proteins, was revealed in a study recently published in Oncotarget. This discovery could help explain why some cancer immunotherapy treatments are less effective for certain patients and lead to new therapeutic strategies. How the Immune System Fights Cancer The immune system is a powerful defense mechanism against cancer, with CD8 T cells acting as the primary soldiers. These specialized immune cells identify and destroy tumor cells. However, cancer can cleverly evade this attack by manipulating immune checkpoints—natural “breaks” on the immune system that prevent it from overreacting and damaging healthy tissue. One of the most studied checkpoints is PD-1 (Programmed Death-1), a receptor on T cells that acts as an “off switch” when activated by tumor cells. This mechanism suppresses the immune response, allowing cancer to grow without control. In response, researchers have developed treatments called PD-1 inhibitors, which block this “off switch” and keep T cells active. The Study: Investigating KLRG1 and PD-1 in Tumor-Fighting T Cells In the study titled “Anti-correlation of KLRG1 and PD-1 expression in human tumor CD8 T cells,” Dr. Steven A. Greenberg from Harvard Medical School analyzed publicly available gene expression data from various cancer types, including lung cancer, melanoma, and colorectal cancer. His goal was to identify immune-related proteins that could complement existing therapies, such as PD-1 inhibitors.

BUFFALO, NY - January 27, 2025 – A new #research paper was #published in Oncotarget's Volume 16 on January 21, 2025, titled “Assessment of cfDNA release dynamics during colorectal cancer surgery." Researchers from the University of Brasília investigated how cell-free DNA (cfDNA) levels in the blood change before, during, and after colorectal cancer surgery. The study found that cfDNA levels increase significantly during and after surgery. The findings suggest that cfDNA could help clinicians evaluate surgery effectiveness and monitor patient outcomes. cfDNA consists of small DNA fragments released into the bloodstream when cells die and break apart. In healthy individuals, cfDNA usually comes from normal cell turnover, while in cancer patients, some of it originates from tumor cells. Measuring cfDNA levels offers valuable insights into a patient’s condition and is already being used to track disease progression and treatment response in cancers such as lung, breast, and colorectal cancer. Colorectal cancer is one of the most common cancers worldwide, affecting millions of people each year. Surgery is often the primary treatment, but up to 50% of patients experience cancer recurrence afterward. In this study, the research team, led by first author Mailson Alves Lopes and corresponding author Fabio Pittella-Silva, analyzed blood samples from 30 patients at three key time points: before, during, and after surgery. It was found that cfDNA levels increased nearly threefold during surgery and doubled after surgery compared to pre-surgery levels. The increases were even higher in individuals over 60, those with preexisting conditions such as diabetes or heart disease, and patients with elevated levels of carcinoembryonic antigen (CEA), a common cancer marker. Patients with the highest cfDNA levels were those with larger or more aggressive tumors, likely due to greater tissue damage during surgery. Additionally, longer surgeries were linked to higher cfDNA levels. “[...]we observed that cfDNA concentration may rise in correlation with the duration of the surgery, highlighting its potential as a marker of surgical quality.” These findings suggest that cfDNA could be a valuable, non-invasive biomarker for clinicians to monitor colorectal cancer patients. Tracking cfDNA levels may help better evaluate surgical outcomes and determine whether patients require closer follow-up care. While these findings are promising, further research is needed to standardize cfDNA testing and validate its usefulness. Larger studies could help establish cfDNA testing as a reliable tool for cancer care and postoperative monitoring, with the potential to become a routine part of clinical practice in the future.

BUFFALO, NY - January 22, 2025 – A new #review was #published in Oncotarget's Volume 16 on January 20, 2025, titled “Evolving concepts in HER2-low breast cancer: Genomic insights, definitions, and treatment paradigms." Researchers Whitney L. Hensing, Emily L. Podany, James J. Sears, Shaili Tapiavala, and Andrew A. Davis from the University of Missouri-KC School of Medicine and Washington University in St. Louis School of Medicine explore HER2-low breast cancer, a recently recognized type of breast cancer that is changing the way clinicians should approach treatment. The review explains what makes HER2-low breast cancer different and highlights new treatment options that are helping patients. “Breast cancer, which has been historically classified as HER2-positive versus HER2-negative, is currently facing a paradigm shift in both the definition of HER2 status and in the existing treatment algorithms.” Breast cancer is usually classified into two main types based on the HER2 protein: HER2-positive or HER2-negative. HER2-low breast cancer falls somewhere in between. Thanks to new targeted treatments, such as a drug called trastuzumab deruxtecan, patients with HER2-low breast cancer now have more options and better chances of responding to treatment. The review looks at recent studies on the genetics of HER2-low breast cancer. Researchers found that these tumors are often hormone receptor (HR)-positive, meaning they respond to hormones like estrogen. Some tumors also carry a common genetic change called a PIK3CA mutation, which could affect how well treatments work. However, experts say HER2-low breast cancer is not a completely separate breast cancer type but rather an opportunity for more personalized treatment. “Despite evidence from existing literature that HER2-low breast cancer does not represent a distinct biologic and prognostic subtype, the introduction of HER2-low expression as a therapeutic target has expanded patient eligibility for a potent class of anti-HER2 drugs, HER2-directed ADCs, with potential for significant efficacy.” Despite these advances, diagnosing HER2-low breast cancer can still be difficult. Current testing methods are not always accurate, and different laboratories may get different results. The review calls for better detection methods to make sure patients who can benefit from these new treatments are correctly identified. With cancer treatments becoming more personalized, the review also explains how clinicians can fit HER2-low treatments into existing guidelines to help patients. The success of targeted therapies is changing how breast cancer is treated, especially for patients whose cancer has metastasized. In conclusion, experts believe ongoing research will continue to improve the way HER2-low breast cancer is diagnosed and treated. However, they stress the need for better detection methods and continued exploration of new therapies to help patients get the best possible care.

BUFFALO, NY - January 21, 2025 – A new #research paper was #published in Oncotarget's Volume 16 on January 20, 2025, titled “Anti-correlation of KLRG1 and PD-1 expression in human tumor CD8 T cells." The study, authored by Dr. Steven A. Greenberg from Harvard Medical School, has discovered a potential new way to improve cancer treatment by studying two key molecules found in immune cells: KLRG1 and PD-1. Analysis of data from cancer patients and healthy individuals revealed that these molecules work in opposite ways in cancer-fighting cells, suggesting that targeting both at the same time could enhance the effectiveness of cancer immunotherapy. “Much effort in the field of immuno-oncology has involved the study of combination therapies, including combinations involving blockade of more than one T cell inhibitory receptor.” The immune system helps fight cancer through specialized cells called T cells. Treatments known as checkpoint inhibitors, which block proteins like PD-1, have been successful in helping these cells attack cancer. However, combining different checkpoint inhibitors has not always provided the expected improvements. This new research focuses on KLRG1, a lesser-known protein, and its relationship with PD-1. The findings suggest that targeting both markers simultaneously could create a stronger and more effective immune response against cancer. Most existing immunotherapy treatments focus only on blocking PD-1, which is commonly found in “exhausted” T cells that struggle to fight cancer. In contrast, KLRG1 is linked to more active, mature T cells that are better at attacking tumors. By blocking both PD-1 and KLRG1, new treatment strategies could help patients with hard-to-treat cancers, such as lung cancer, melanoma, and colorectal cancer. KLRG1 has not been widely studied in cancer immunotherapy, but this research highlights its potential to revolutionize treatment strategies. While current combinations of checkpoint inhibitors have shown only limited improvements, using therapies that target both PD-1 and KLRG1 could lead to more significant and long-lasting benefits. “Whereas much of the T cell inhibitory drug development efforts over the last decade have been focused on combinations of expression-correlated inhibitory receptor targets, the targeting of anti-correlated inhibitory receptors has greater potential to produce supra-additive benefit, and KLRG1 has this distinct property.” Further studies and clinical trials are needed to explore how combining PD-1 and KLRG1 treatments could benefit different types of cancer. If successful, this strategy could open the door for the creation of new combined immunotherapies. DOI - https://doi.org/10.18632/oncotarget.28679 Correspondence to - Steven A.

Scientists have discovered that a genetic variant called KIT M541L may play an important role in a rare immune disorder known as #mastocytosis. The findings may help explain why some #patients develop more severe forms of the disease. Understanding Mastocytosis Mastocytosis is a condition where the body produces too many mast cells. These cells are part of the immune system and help the body fight infections, but in excess, they release chemicals that can cause itching, swelling, and even serious organ damage. There are two main types of mastocytosis. The first is cutaneous mastocytosis, which mostly affects the skin. The second is systemic mastocytosis, a more serious form where mast cells build up in internal organs like the liver, spleen, and bone marrow. The disease is linked to mutations in the KIT gene, which regulates mast cell growth. The most studied mutation is KIT D816V, but recent research has highlighted another variant, KIT M541L. The Study: Impact of KIT M541L Variant A team of researchers at the National Institutes of Health (NIH), led by first author Luisa N. Dominguez Aldama and corresponding author Melody C. Carter, aimed to better understand the prevalence and impact of the KIT M541L genetic variant in mastocytosis patients. The study published in Oncotarget on July 22, 2024, titled “Prevalence and impact of the KIT M541L variant in patients with mastocytosis,” examined the presence of the KIT M541L gene variant in 100 patients with mastocytosis, both adults and children, alongside 500 healthy individuals. By comparing these two groups, the researchers wanted to see if there was a relation between the KIT M541L variant and mastocytosis severity.

Would you take a test to find out your cancer risk? At-home genetic testing makes it easy, but experts warn that these tests may create more harm than good. A New Approach to Genetic Testing Genetic testing has traditionally been performed under the supervision of healthcare providers, with genetic counseling to help patients navigate their results. This approach ensures that individuals receive proper guidance, reducing the emotional and practical challenges of interpreting complex genetic information. In September 2023, the United States Food and Drug Administration (FDA) approved a new test called the Invitae Common Hereditary Cancers Panel. This test checks for changes in 48 genes linked to hereditary cancers, including breast, ovarian, and Lynch syndrome-related cancers. What makes it different is that it can be ordered online and taken at home with no doctor required. While the convenience of these tests is appealing, health experts have raised serious concerns. An editorial titled “Pitfalls and Perils from FDA-Approved Germ-line Cancer Predisposition Tests,” authored by Dr. Wafik S. El-Deiry, Editor-in-Chief of Oncotarget, and Dr. Eli Y. Adashi, both from Brown University, highlights the potential risks of using these tests without professional guidance.

BUFFALO, NY - December 30, 2024 – A new #editorial was #published in Oncotarget's Volume 15 on December 24, 2024, titled “Pitfalls and perils from FDA-approved germ-line cancer predisposition tests." Authored by Dr. Wafik S. El-Deiry, Editor-in-Chief of Oncotarget, and Dr. Eli Y. Adashi from Brown University, the article highlights concerns about the risks of a newly approved genetic test for cancer risk. This test, called the “Invitae Common Hereditary Cancers Panel," was approved in 2023 and examines 48 genes linked to inherited cancers, including breast, ovarian, and Lynch syndrome-related cancers. Although the test increases access to genetic information, the authors warn that using it without professional guidance may lead to confusion, stress, and potential harm. One concern is that people can order this test online without consulting healthcare professionals or genetic counselors. Without expert help, users might struggle to understand their results especially if they indicate risks that are unclear or difficult to act on. This can cause unnecessary anxiety and confusion. “The DTC option of germ-line testing for cancer susceptibility should be discouraged given the risks of anxiety, lack of adequate interpretation for variants not strongly associated with cancer, potential for minors to be tested outside the healthcare system and potential for loss of follow-up if test results are not shared with health care professionals or never make it into the medical record.” The editorial also points out ethical and medical issues when minors use these tests. If a child’s test is done without medical oversight, results might not be added to their health records, making follow-up care harder to manage and potentially risking their long-term health. Cost is another issue. These tests are often not covered by insurance, which can place a financial burden on families who might need additional testing or medical advice. The researchers emphasize that genetic testing for cancer risk should always include healthcare providers and genetic counseling. This ensures users fully understand their results and receive proper guidance. The authors also call on the US Food and Drug Administration (FDA) to provide clear rules for using these tests, particularly for minors. In conclusion, while genetic testing holds great potential for improving cancer prevention and care, its benefits must not come at the cost of safety and public health. Responsible use of these tests will require collaboration between regulators, healthcare professionals, and testing companies to address the risks and ensure these tools are used effectively.

The p53 protein, often called the “guardian of the genome,” is crucial for preventing cancer by repairing damaged DNA or triggering cell death in cells that cannot be repaired. However, in about half of all cancers, the p53 gene is mutated, making the protein ineffective. A groundbreaking study has introduced PG3, a new compound that restores tumor suppression without relying on p53, offering a new option to treat resistant cancers. Published in Oncotarget on September 17, 2024, the study titled “Integrated stress response (ISR) activation and apoptosis through HRI kinase by PG3 and other p53 pathway-restoring cancer therapeutics,” introduces PG3, a small molecule with a completely new approach to treating cancer. This groundbreaking research was conducted by Dr. Xiaobing Tian and Oncotarget Editor-in-Chief Dr. Wafik S. El-Deiry from Brown University. The researchers tested PG3 on cancer cell lines with various p53 mutations, as well as on cells that lacked p53 entirely.

BUFFALO, NY - December 11, 2024 – A #news feature on the #research paper “Next-generation cell-penetrating antibodies for tumor targeting and RAD51 inhibition” by Rackear et al. was #published in Oncotarget's Volume 15 on November 22, 2024, titled “Advancements in cell-penetrating monoclonal antibody treatment." This new publication by Sai Pallavi Pradeep and Raman Bahal from the Department of Pharmaceutical Sciences at the University of Connecticut highlights significant advancements in monoclonal antibody (mAb) therapies. The focus is on the 3E10 antibody, originally derived from autoimmune mouse studies in systemic lupus erythematosus. Unlike traditional mAbs, which struggle to reach intracellular targets, this cell-penetrating antibody targets cancer cells by addressing a major limitation of current therapies. By targeting RAD51, a key intracellular protein involved in DNA repair, the 3E10 antibody shows great promise for cancer treatment, particularly in cancers with defective DNA repair pathways. mAbs have already changed the landscape of cancer therapy, offering treatments that are more targeted and have fewer side effects compared to chemotherapy. However, current therapies are limited since mAbs only target proteins on the surface of cancer cells. This research pushes the boundaries by demonstrating how 3E10 antibodies can penetrate cells and access their internal molecules. This unique capability expands the potential of mAb therapies and targeted cancer treatments. Different humanized versions of the 3E10 antibody were created and carefully tested. Some versions were particularly effective at blocking RAD51, while others showed promise for carrying other therapeutic molecules like genetic material into the cancer cells. This flexibility means that 3E10 could be used to treat different cancer types and deliver various therapeutic molecules directly into tumor cells. This progress offers exciting new possibilities for treating cancer tumors that are resistant to conventional therapies. In conclusion, the 3E10 antibody’s dual function—targeting DNA repair pathways and delivering therapeutic molecules—positions it as a transformative tool in cancer research and targeted cancer treatments.

BUFFALO, NY - December 9, 2024 – A new #research paper was #published in Oncotarget's Volume 15 on November 22, 2024, entitled “Computed tomography-based radiomics and body composition model for predicting hepatic decompensation." Mayo Clinic researchers Yashbir Singh, John E. Eaton, Sudhakar K. Venkatesh, and Bradley J. Erickson have developed an innovative AI tool to predict hepatic decompensation in individuals with primary sclerosing cholangitis (PSC). PSC is a chronic disease that damages the bile ducts and can lead to liver failure. Hepatic decompensation marks a critical stage of advanced liver disease, and clinicians have long faced challenges in predicting who is at risk. The Mayo Clinic's new AI tool addresses this gap by combining body fat and muscle composition data with insights extracted from computed tomography (CT) scans using computational radiomics. By analyzing these tissues, the AI model identifies patterns linked to an increased risk of liver failure. The study involved 80 PSC patients, including 30 with hepatic decompensation, 30 without, and 20 patients in an external validation set. The AI model achieved impressive results, correctly identifying at-risk patients with 97% accuracy. By recognizing these risks early, clinicians may be able to intervene sooner and improve patient outcomes. While the study focused on PSC, the team emphasized the broader implications of their work. “It may hold promise for the detection of other PSC-related complications, such as cholangiocarcinoma, as well as applications in more prevalent chronic liver diseases like non-alcoholic fatty liver disease (NAFLD).” This non-invasive, data-driven approach offers a powerful way to assess health risks and provide more tailored treatments. Despite the promising findings, the researchers acknowledge the limitations of the study, which include a limited sample size and a single-center design. “However, further research is necessary to validate our findings on a large-scale, independent dataset, ensuring the robustness and generalizability of the model.” In conclusion, this study shows how detailed information from CT scans can help clinicians predict severe liver problems in patients with PSC. By identifying hidden patterns in the images, they can better understand risks and create personalized treatment plans. This approach could improve care for PSC and other long-term liver diseases.

“Precision medicine is an innovative approach to disease prevention and treatment that considers differences in people’s genes, injuries, environments, and lifestyles to target the right therapies to the right patients at the right time.” Could a deeper understanding of one of the deadliest lung cancers lead to more effective treatments? Recent research offers a promising way forward, aiming to improve patient outcomes and provide clinicians with valuable insights. Small Cell Lung Cancer (SCLC) is a particularly aggressive form of lung cancer. It spreads fast and does not always respond well to conventional therapies such as chemotherapy. Although SCLC accounts for around 15% of all lung cancer cases, survival rates are extremely low. Only less than 5% of patients live more than five years after diagnosis. These alarming statistics highlight the critical need for new treatments. A team of researchers from the Federal University of Ceará, working together with collaborators from Argentina and Spain, may have found part of the solution.
