The present study is the first to characterize the phenotype associated with the HRR-deficient genotype in healthy individuals with a familial history of HBOC. Metabolomic profiles may be useful for differentiating carriers from noncarriers of PVs in the HRR genes, and therefore, with potential predictive capacity of the HRR germline mutational status.

Management strategies for male breast cancer generally parallel female protocols, despite unique biological features. By integrating considerations of benign and malignant conditions, this review underscores the importance of tailored evaluation, risk assessment, and individualized care for males, while identifying knowledge gaps to inform future research and improve outcomes in this under-recognized population.

This review integrates the current evidence and evolving guidelines to clarify the benefits, limitations, and controversies surrounding RRM. By addressing existing knowledge gaps and decision-making challenges, it aims to facilitate informed patient-centered counseling for the management of hereditary breast cancer.

Functional assays further demonstrated that MSH2 downregulation impaired ATM-CHK2-mediated DNA damage response and promoted cell cycle acceleration. MSH2 exerts its tumor-suppressive effects in hepatocytes not only through canonical MMR but also by regulating the cell cycle via the ATM-CHK2 axis.

HPMC-based SD enhances BIBR1532 solubility and bioavailability for effective ESCC treatment. Future studies should focus on pilot tests for SD fabrication.

These effects are associated with the downregulation of key cell cycle regulators, including CCNA2/B1 and CHEK1. Together, these findings highlight the potential of Linarin as a promising therapeutic option for NSCLC.

In this study, we found that intraperitoneal injection of retinoic acid (RA) and calcitriol partially reversed the cyclophosphamide and doxorubicin treatment-induced decrease in primordial follicles in neonatal mouse ovaries. Thus, RA and calcitriol protect mouse primordial follicles from cyclophosphamide treatment-induced apoptosis by inhibiting cyclophosphamide treatment-induced oocyte transcriptional activity and enhancing antioxidant capacity. Our results suggest a potential strategy for preserving ovarian reserve during chemotherapy in female cancer patients.

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.

Median overall survival (OS) 131 months (1-, 2-, 5-, 10-year OS: 95%, 93%, 73%, 53%). This long-term cohort highlights the predominance of hormone-receptor positivity, the infrequency of germline mutations, and moderate survival rates, informing patient management and guiding future studies.

Exclusion criteria included works not related to BAK or its therapeutic use in breast cancer, as well as publications that did not meet basic scientific standards, such as lacking methodological rigor or presenting a low level of scientific evidence. However, current evidence is predominantly in vitro, and limitations such as poor bioavailability and lack of clinical validation underscore the need for further in vivo and translational studies before therapeutic application can be established.

Constitutional CHEK2 mutations combined with somatic NF1 defect may have promoted the malignant progression of SEGA-imitating fibrous meningioma and its favorable initial response to mTOR inhibitors.
