Renal oncocytoma is a rare benign kidney tumor arising from the intercalated cells of the distal renal tubules. These tumors are often asymptomatic and incidentally discovered on imaging. This report presents an 82-year-old female patient with gross hematuria, who was subsequently diagnosed with a small renal oncocytoma. A computed tomography (CT) scan of the abdomen revealed a lesion in the upper left kidney, diagnosed as a renal oncocytoma by histopathological examination of a tissue specimen obtained via a CT-guided biopsy. After multidisciplinary review, the tumor board recommended local treatment with percutaneous cryoablation due to the lesion&#x2019;s small size and indolent nature. The patient has been on annual follow-up with imaging showing no disease progression over two years. This case highlights the management considerations for renal oncocytoma, particularly in elderly patients, and underscores the role of biopsy and multidisciplinary evaluation in deciding optimal, minimally invasive treatment strategies for benign renal tumors.</p>","PeriodicalId":19499,"journal":{"name":"Oncotarget","volume":"17 1","pages":"332-336"},"PeriodicalIF":0.0,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13367981/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148448538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breast cancer is considered to be one of the most widespread malignancies, however, its molecular processes are not fully comprehended. Another important epigenetic process that regulates the expression of genes in cancer is promoter methylation. TRAIL-R2 is also a key mediator of apoptosis but its clinical implications and epigenetic regulation in breast cancer are not clearly understood. In this research, the level of the promoter of the gene TRAIL-R2 in the matched tumor and normal breast tissues was analyzed using methylation-specific PCR and the level of the mRNA and protein products in the matched tumor and normal breast tissues were measured using quantitative real-time PCR and western blotting. Methylation of TRAIL-R2 promoter was significantly enhanced in tumor tissues and was negatively correlated with the levels of mRNA and protein. We found that hypermethylation was much more common in invasive ductal carcinoma patients and in patients with a history of use of oral contraceptives. A decreased expression of mRNA of TRAIL-R2 was significantly related to advanced TNM stage (III&#x2013;IV) and the absence of progesterone receptor, and low protein expression was significantly related to postmenopausal status. These results suggest that aggressive clinicopathological phenotypes are associated with TRAIL-R2 silencing via promoter hypermethylation that may be relevant as a prognostic biomarker and therapeutic target in breast cancer.</p>","PeriodicalId":19499,"journal":{"name":"Oncotarget","volume":"17 1","pages":"316-328"},"PeriodicalIF":0.0,"publicationDate":"2026-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13637834/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148345879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The protein-acyltransferase DHHC3 supports a few different tumor malignancies, but mechanisms have been unclear.

Unexpectedly, DHHC3 ablation minimally affected experimental metastasis of cells injected into either immunocompetent C57/BL6 or immunodeficient NOD-SCID mice.

There remains an unmet need for effective drugs targeting KRAS-driven cancers. Polyisoprenylated cysteinyl amide inhibitors (PCAIs) were designed to disrupt hyperactive mutant KRAS in cancer. Here, we determined the effects of PCAIs on the viability and downstream mediators of KRAS on pancreatic cancer-derived PANC-1 and MIAPaCa-2 cells. NSL-YHJ-2-45 and NSL-YHJ-2-27 were the most potent of the analogs with EC50 values of 3.6 and 3.8 &#x03BC;M, respectively. NSL-YHJ-2-27 treatment of PANC-1 cells stimulated BRAF, MEK 1/2, ERK 1/2 and p90RSK phosphorylation levels by 64 to 150% while CRAF phosphorylation significantly decreased by 27%. Furthermore, 5 &#x03BC;M NSL-YHJ-2-27 depleted 20 to 61% of the monomeric G-proteins, CDC42, RHOA and RAC 1/2/3 while increasing pAKT (Ser 473) and pAKT (Thr 308) phosphorylation by 72 and 190%, respectively. Reactive oxygen species production significantly increased at 3 &#x03BC;M NSL-YHJ-27 in PANC-1 and MIA PaCa-2 by 2- and 9-fold, respectively. Bulk RNA sequencing analysis revealed that treatment of MIA PaCa-2 cells with 3 &#x03BC;M NSL-YHJ-27 resulted in significant differential expression of 88 genes. NSLYHJ-2-27 at 1 &#x03BC;M inhibited over 90% of pancreatic cancer cell migration. The PCAIs induced apoptosis in both PANC-1 and MIA PaCa-2 3D spheroids while doubling caspase 3/7 activity in PANC-1 cells.

Collagen triple helix repeat containing 1 (CTHRC1) is a secreted protein that has previously been explored for its role in tissue remodeling and cancer. However, its function in the tumor microenvironment (TME) remains poorly understood, despite its known expression in tumor-associated stroma. Colorectal cancer (CRC), a malignancy characterized by extensive stromal involvement, poses an excellent opportunity to investigate this gap. Here, we provide the first evidence that host-derived CTHRC1 drives colon cancer progression, with this effect consistently observed across three independent cohorts. Specifically, when injected with CRC cells, Cthrc1 null (global knockout, KO) mice develop significantly smaller and less dense tumors compared to wild-type (WT) mice. Additionally, median survival increased approximately 2.5-fold in Cthrc1 KO mice, from 28 days post-inoculation in WT (n = 10) to 69 days in CTHRC1-deficient mice (n = 10), suggesting CTHRC1 promotes tumor growth within the TME. Immune cell profiling revealed differences in the composition of tumors and spleens of these mice; specifically, Cthrc1 KO mice exhibited an increased percentage of CD3+ T cells in both tumors and spleens and decreased Gr-1+ myeloid cells in the spleen, compared to WT, indicating an immunoregulatory role for CTHRC1 in CRC. These results identify CTHRC1 as a key driver of CRC that may suppress the immune system, allowing for easier immune evasion by tumor cells, highlighting CTHRC1 as a potential new target for therapy.</p>","PeriodicalId":19499,"journal":{"name":"Oncotarget","volume":"17 1","pages":"258-267"},"PeriodicalIF":0.0,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13235751/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148033760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple myeloma (MM), the second most common hematologic malignancy in the United States, has undergone transformative therapeutic innovation over the past five decades. Using SEER data from 1975 to 2023, we conducted a retrospective cross-sectional analysis to evaluate MM-specific mortality trends in relation to major treatment milestones. Age-adjusted mortality rates and Annual Percent Change (APC) were estimated using Joinpoint regression. Mortality increased from 1975 to 1994 (APC: 1.43%; P &lt; .01), declined modestly from 1994 to 2002 (&#x2013;0.70%; P = .02), dropped steeply from 2002 to 2009 (&#x2013;1.85%; P &lt; .01), plateaued between 2009 and 2014 (0.52%; P = .10), resumed decline from 2014 to 2021 (&#x2013;1.73%; P &lt; .01), and sharply decreased from 2021 to 2023 (&#x2013;5.64%; P &lt; .01). These inflection points align with the introduction of stem cell transplantation, proteasome inhibitors, immunomodulatory drugs, and next-generation immunotherapies including CAR T-cell therapy and bispecific antibodies. While these advances have improved survival, they also introduced chronic treatment burdens and rising costs.
