SETD2 (SET Domain Containing 2, Histone Lysine Methyltransferase)

After a median follow-up of 33.5 months, 36% of patients developed distant metastases, and 2 patients died of disease 8 and 32 months, respectively, after initial diagnosis. These findings expand the molecular diversity of DPN-like melanomas and provide valuable insights into their clinical outcomes.

ctDNA testing offers complementary insights to tissue NGS in RCC, particularly in metastatic disease, suggesting the potential utility of ctDNA in advanced RCC. Longitudinal analysis may enhance delineation of biomarkers of response and resistance at mutation and ctDNA fraction levels.

Mechanistically, SETD2 methylates SRSF2P95H at lysine-17 and lysine-65 to inhibit aberrant splicing of CEACAM1-4 (isoforms of carcinoembryonic antigen cell adhesion molecule), which enhances interleukin-1β (IL-1β) signaling through Slc7a11 (solute carrier family 7 member 11)-mediated cystine uptake, thereby promoting HSPC differentiation into MDSCs, establishing an IL-1β-driven immunosuppressive microenvironment. These findings identify the SRSF2P95HK17me1K65me2-CEACAM1-4 signaling axis as a promising therapeutic target in SRSF2P95-Mut MDS.

In addition, germline mutations are present in a subset of patients with mesothelioma and primarily involve genes in the DNA repair and cell cycle regulation and are more common in patients who are young, with family history of mesothelioma, or with peritoneal mesothelioma. In this review, we discuss the considerable heterogeneity of mesothelioma, the diversity of radiologic and gross presentation, various morphologic features with distinctive histologies and ultimately, we individually describe subsets of tumors characterized by uncommon alterations such as germline mutations, genomic near-haploidization, ALK rearrangement, ATF1 rearrangement, or EWSR1::YY1 fusion, as well as the implications of these findings on the diagnostic workup.

This study identifies a proteomics-derived multi-omics signature associated with platinum resistance and prognosis in OC and highlights MSH6 as a candidate marker linked to chemoresistant and immune-related features. Further mechanistic and clinical validation is needed.

This study presents data that can help draw conclusions on common mutations, mutual exclusivity patterns, and demographics at risk for peritoneal mesothelioma. Genomic analysis of peritoneal mesothelioma may inform possible intervention targets for therapeutic treatment.

This study expands the repertoire of histone modification and diversifies the mechanisms underlying CLOCK-implicated chromatin dynamics. It also unearths an undocumented mechanistic link between dysregulated circadian CLOCK and decreased H3K36me3 pathways in glioblastoma.

Additionally, alternative polyadenylation upon SETD2 activity loss is highly cell type specific, and no relationship with transcription readthrough was observed. We demonstrate that methyltransferase activity of SETD2 stimulates proper initiation, prevents cryptic initiation and promotes efficient 3' end processing, however, it does so indirectly.

Cisplatin (CIS)-resistant cells were established, and SETD2 and TKT expression levels were assessed via Western blot...Additionally, SETD2 overexpression suppressed tumor growth by down-regulating TKT, reduced glycolysis level in tumor tissues, promoted apoptosis and inhibited proliferation of tumor cells. In conclusion, SETD2 inhibits glycolysis by directly suppressing TKT transcription, thereby attenuating malignant progression and enhancing chemosensitivity in LUAD.

These findings suggest that somatic genomic alterations identified at prostatectomy are associated with early recurrence in localized PC. Further validation in independent cohorts is required to determine whether genomic profiling may contribute to future risk stratification and management strategies.

These findings suggest that the long-lived inflammatory cells may compensate for the HSC self-renewal defects, triggering systemic inflammation and driving hematopoietic malignant transformation. This paradigm provides a new understanding of hematopoietic malignancies with functional defects and exhaustion of HSCs.
