RAD50 (RAD50 Double Strand Break Repair Protein)

As the inaugural germline genomic investigation of MaBC in a Han Chinese population, this work reveals clinically actionable alterations with diagnostic and therapeutic implications. These discoveries not only advance our understanding of MaBC's molecular architecture but also underscore the critical need for dedicated research into this malignancy.

Mirin suppressed lymph node metastasis of PCa cells in vivo. Our study demonstrated a novel function of the YEATS2/NR2C2/RAD50 axis in regulating DNA damage responses and anoikis resistance in PCa metastasis, highlighting an important pathway that drives metastatic progression and offering potential new strategies for treating mPCa.

Germline DDR alterations-most notably in BRCA2, CHEK2, and ATM-were present in a substantial subset of Turkish men with PCa and showed a non-significant trend toward clustering in higher-grade disease. The high prevalence of VUS reflects limited genomic annotation in under-represented populations and underscores the need for longitudinal reinterpretation. These data support the clinical value of incorporating germline DDR testing into risk assessment and familial counseling, while larger cohorts integrating somatic profiling are needed to refine genotype-phenotype associations.

Comparative genomic analyses of populations in cold and arid environments identified several candidate genes related to energy and water homeostasis, as well as hair development (TP53 [Tumor Protein P53], ATG101 [Autophagy Related 101], ATP12A [ATPase H+/K+ Transporting Non-Gastric Alpha2 Subunit], KRT80 [Keratin 80], KRT7 [Keratin 7]). Additionally, Tibetan sheep in the high-altitude arid deserts exhibit stronger adaptive selection for energy homeostasis and water utilization; meanwhile, the HIF-1 [Hypoxia Inducible Factor 1] signaling pathway helps counteract oxidative stress induced by extreme water scarcity in the plateau environment. Our study supports the hypothesis that Tibetan sheep originated in northern China and identifies distinct adaptive features in the Tibetan sheep genome corresponding to their habitats.

Second, we report a pathogenic germline variant in RAD50 in a patient with a rare prostate primary EwS and later concurrent relapsed EwS and therapy-related acute myeloid leukemia (tAML) with two rare KMT2A translocations. Understanding rare pathogenic germline variants and the impact on cancer behavior, response to treatment and treatment-associated toxicities is important for patients.

Sixty-three mutated genes were unique to stage II tumors, while 36 mutated genes were exclusively present in stage IV tumors. Pathway analyses demonstrated the PI3K-AKT pathway was shared by both stage II and stage IV tumors, whereas multiple other signaling pathways showed disease stage-specific enrichment.ConclusionThere were profound differences in mutational profile and molecular mechanisms between stage II and stage IV dMMR/MSI-H CRC.

Moreover, MRE11 K393 deacetylation by SIRT2 promoted ATM-dependent signaling. Our findings define a mechanism regulating MRE11 binding to DNA through SIRT2 deacetylation, elucidating a critical upstream signaling event directing MRE11 function in the DDR and providing insight into how SIRT2 dysregulation leads to genomic instability and tumorigenesis.
