    Restoring MHC-I Expression Could Strengthen Immune Responses Against CNS Cancers

    BUFFALO, NY – September 9, 2026 – A new #review was #published in Volume 17 of Oncotarget on September 8, 2026, titled “Re-expression of MHC-I to treat CNS cancers.” The review examines emerging strategies to restore major histocompatibility complex class I (MHC-I) expression in cancers of the central nervous system (CNS), with the goal of making these tumors more visible and vulnerable to immune attack. The review was authored by Arseniy E. Yuzhalin from the Sirius University of Science and Technology in Sochi, Russia. Malignant central nervous system (CNS) tumors such as glioblastoma and brain metastases are often immunologically “cold,” with limited T-cell infiltration and poor responses to immune checkpoint therapy. One important mechanism of immune escape is the reduction or loss of major histocompatibility complex class I (MHC-I), which normally displays tumor-associated antigens to cytotoxic CD8+ T cells. When MHC-I expression falls, cancer cells become less visible to immune surveillance. The review examines several strategies for restoring MHC-I expression. Epigenetic therapies, including histone deacetylase and DNA methyltransferase inhibitors, could potentially reverse epigenetic silencing of MHC-I genes, although blood-brain barrier penetration remains a major limitation in CNS cancers. A more direct approach could use adeno-associated virus (AAV) vectors to deliver patient-specific HLA-A, HLA-B, or HLA-C genes or transcription factors such as NLRC5 that promote MHC-I expression. However, efficient tumor targeting, gene delivery, and control of the immunosuppressive tumor microenvironment remain unresolved challenges. The review also highlights PCSK9 inhibition as a clinically relevant strategy. PCSK9 can promote MHC-I degradation, and a recent surgical-window trial tested the cholesterol-lowering drug evolocumab in patients with newly diagnosed or recurrent glioma. A single preoperative dose showed measurable blood-brain barrier penetration, and tumors with higher drug concentrations displayed increased surface MHC-I expression, greater CD8+ T-cell infiltration, and enhanced cytotoxic activity. These findings provide proof-of-mechanism, although drug delivery into the brain remains a limiting factor.

    Therapeutic HPV Vaccine PepCan Tested for Preventing Head and Neck Cancer Recurrence

    Head and neck squamous cell carcinoma (HNSCC) can return even after patients complete surgery, radiation, chemotherapy, or combinations of these treatments. Preventing recurrence therefore remains an important challenge in head and neck cancer care. Human papillomavirus (HPV), particularly HPV type 16, is also an established cause of a subset of these cancers, especially oropharyngeal squamous cell carcinoma. A research paper published in Volume 17 of Oncotarget, titled “A randomized double-blind placebo-controlled phase I/II clinical trial of a human papillomavirus therapeutic vaccine, PepCan, for reducing head and neck squamous cell carcinoma recurrence,” investigated whether an experimental therapeutic HPV vaccine could safely reduce the risk of HNSCC recurrence after standard treatment.

    Tumor-Derived Extracellular Vesicles Show Promise for Earlier Detection of Metastatic Risk

    BUFFALO, NY – September 1, 2026 – A new #review was published in Volume 17 of Oncotarget on August 28, 2026, titled “Emerging biomedical imaging applications of tumor-derived extracellular vesicles for premetastatic niche detection: Biological rationale, engineering strategies, and translational challenges.” The review was led by first author Omkar Dhaygude, who is affiliated with Johns Hopkins University. Corresponding authors Franck Housseau and John Michel are affiliated with Johns Hopkins University, with Housseau also affiliated with the Cancer Research Center of Lille in France. Extracellular vesicles (EVs) are membrane-enclosed particles released by cells that transport proteins, lipids, nucleic acids, metabolites, and other molecular cargo. In cancer, tumor-derived extracellular vesicles (TEVs) can influence the tumor microenvironment and distant tissues by promoting processes such as angiogenesis, extracellular matrix remodeling, inflammatory signaling, immune evasion, and stromal reprogramming. Of particular interest is the role of TEVs in establishing premetastatic niches—biological environments in distant organs that become permissive to metastatic cells before overt tumors are detectable. TEVs can carry organ-specific molecular signals, and their surface molecules may influence which tissues they reach. For example, previous experimental research has linked the integrins α6β4 and α6β1 with lung tropism, providing a biological rationale for using TEVs to direct imaging probes toward metastasis-prone organs. This possibility could address an important limitation of conventional cancer imaging. Computed tomography and other anatomical methods are designed primarily to detect established structural lesions, whereas premetastatic niches are characterized by earlier molecular and microenvironmental alterations. The authors therefore examine whether TEV-associated imaging could provide information about metastatic conditioning before conventional imaging can identify overt metastatic lesions.

    Tumor-Infiltrating Lymphocyte Therapy Offers a Promising Approach for Treating Solid Tumors

    BUFFALO, NY – August 31, 2026 – A new #editorial was published in Volume 17 of Oncotarget on June 8, 2026, titled “Tumor infiltrating lymphocyte (TIL) therapy for treating the solid tumors: Challenges and future perspectives.” The editorial was led by first and corresponding author Bhartendra Sharma from Mahatma Gandhi University of Medical Sciences and Technology, Jaipur, Rajasthan, India, along with co-authors Sukhbir Kaur, Vikas Sharma and Sanjay Soni. Tumor-infiltrating lymphocyte (TIL) therapy is a form of adoptive cellular therapy that uses immune cells naturally present within tumors to attack cancer. Unlike chimeric antigen receptor (CAR) T-cell therapy, which genetically modifies a patient’s T cells to recognize specific tumor antigens and has achieved its greatest success in hematological malignancies, TIL therapy has shown potential in several types of solid tumors. The approach has a history spanning more than four decades. Steven Rosenberg first isolated TILs from a mouse tumor in 1982, and subsequent experiments demonstrated antitumor effects when TILs were combined with cyclophosphamide and interleukin-2 (IL-2). In 1988, Rosenberg and colleagues reported favorable clinical outcomes after administering TIL therapy to patients with metastatic melanoma.

    KRAS G12C Mutation Identified as a Rare Potential Target in Genitourinary Cancers

    BUFFALO, NY – August 28, 2026 – A new #research paper was published in Volume 17 of Oncotarget on August 19, 2026, titled “Incidence of KRAS G12C mutations in genitourinary malignancies; emerging target in precision medicine.” The study was led by first author Kelly Crane from the Department of Urology at SUNY Upstate Medical University. The corresponding author is K. R. Seetharam Bhat, who is affiliated with the Department of Urology at SUNY Upstate Medical University and Upstate Urology at MVHS. KRAS is one of the most extensively studied oncogenes in cancer, and the G12C variant has become clinically important following the development of mutation-specific inhibitors. Although KRAS G12C-targeted therapy is established in other malignancies, its frequency and genomic characteristics in genitourinary cancers have remained less well defined. To address this gap, the researchers performed comprehensive genomic profiling of 13,654 tumor specimens from patients with metastatic disease, including 1,453 renal clear cell carcinomas, 3,879 urothelial bladder carcinomas, and 8,322 prostate acinar adenocarcinomas. Tumor mutational burden, microsatellite instability, and PD-L1 expression were also evaluated. Across the full cohort, KRAS alterations were detected in 367 tumors, or 2.7%, while KRAS G12C was identified in only 25 tumors, representing approximately 0.2% of all specimens. No G12C variants were found among the renal clear cell carcinomas. In urothelial bladder carcinoma, 24 of 202 KRAS-altered tumors, or 12%, carried G12C, while only one of 158 KRAS-altered prostate tumors contained the variant.

    New Analysis Challenges Methods Used to Measure Residual DNA in mRNA Vaccines

    BUFFALO, NY – August 25, 2026 – A new precision oncology paper was #published in Volume 17 of Oncotarget on August 14, 2026, titled “Systematic methodological flaws in DNA contamination assessment of mRNA vaccines: A critical analysis of Achs et al. (2025).” The article was led by first and corresponding author Kevin McKernan from Medicinal Genomics, Beverly, Massachusetts, along with co-authors David J. Speicher from Cyrus Scientific Inc, Hamilton, Ontario, Canada, and Jessica Rose from Brownstone Institute, Austin, Texas. Rather than presenting a new experimental vaccine analysis, the paper critically examines the methodology used by Achs et al. in a 2025 study that reported no excessive residual DNA impurities in COVID-19 mRNA vaccines. McKernan and colleagues argue that several methodological choices in that study could systematically underestimate residual DNA and therefore limit its suitability for regulatory safety assessment. One major concern involves how quantitative PCR results were converted from DNA copy numbers into mass. Achs et al. used full-length plasmid molecular weight in their calculations even though their own sequencing data suggested much shorter median DNA fragment sizes. The critique argues that this approach requires fragmentation-correction factors because random DNA breakage can disrupt qPCR target regions and reduce the number of detectable amplicons. Without such correction, the authors contend that residual DNA mass may be underestimated. The paper also highlights the importance of primer and amplicon design. Achs et al. used qPCR targets with substantially different amplicon lengths, including shorter kanamycin-resistance targets and longer spike-encoding targets. Because the reported median DNA fragment sizes were approximately 130–201 base pairs, longer amplicons would be less likely to remain intact after fragmentation. The authors therefore argue that this design could preferentially reduce detection of spike-associated DNA relative to shorter plasmid regions.

    Experimental Compounds Push Cancer-Promoting Pathways Into Overdrive in Pancreatic Cancer Cells

    Pancreatic cancer remains one of the most difficult cancers to treat, in part because mutations in the KRAS gene are extraordinarily common in pancreatic ductal adenocarcinoma (PDAC). These mutations keep growth-promoting signals switched on, allowing cancer cells to proliferate and survive. Although drugs targeting certain KRAS mutations have emerged in recent years, they work against only a subset of mutant forms, leaving a need for strategies capable of targeting a broader range of KRAS-driven cancers. A research paper published in Volume 17 of Oncotarget, titled “The anticancer effects of PCAIs in pancreatic cancer cells involve MAPK and PI3K/AKT pathways hyperactivation,” investigated a class of experimental compounds known as polyisoprenylated cysteinyl amide inhibitors, or PCAIs. Rather than simply shutting down signaling pathways normally associated with cancer growth, the researchers uncovered a more unexpected effect: PCAIs pushed some of these pathways into unusually high activity while simultaneously promoting oxidative stress, disrupting cell structure, and triggering cancer cell death.
