PARylation-centric crosstalk: orchestrating immune evasion and multidrug resistance in ovarian cancer. (PubMed, Front Immunol)
Emerging strategies combining PARP inhibitors with PRMT, UBA1, WEE1, or MEK inhibitors are examined, alongside recent clinical trials including the GINECO study of bevacizumab, olaparib, and durvalumab. Current obstacles in resolving spatiotemporal PTM dynamics and cancer stem cell-specific vulnerabilities are outlined. This work aims to inform future research on targeting PARylation-associated PTM pathways to overcome ovarian cancer's evolvable resistance.

Integrative Mendelian Randomization and Multiomics Analysis Identifies CAF-Derived Complement Factor B as a Prognostic Biomarker and Therapeutic Vulnerability in Breast Cancer. (PubMed, Hum Mutat)
Mechanistically, CFB expression strongly correlated with PARP1 (R = 0.77), and CAF-derived CFB enhanced olaparib-induced DNA damage in TNBC models. Through integrative traditional and AI-driven approaches, this study supports CFB as a genetically associated risk protein with potential causal relevance and as a prognostic and therapeutic biomarker at both the expression and mutation levels in breast cancer. These findings provide a mechanistic and translational basis for precision therapy targeting CFB-overexpressing tumors.

Pan-Cancer Landscape of Thymine DNA Glycosylase and Its Potential Role in Lung Adenocarcinoma. (PubMed, Zhongguo Yi Xue Ke Xue Yuan Xue Bao)
Additionally,TDG expression was positively associated with tumor mutational burden (P<0.001),microsatellite instability (P=0.045),mutant-allele tumor heterogeneity (P=0.001),and tumor neoantigens (P<0.001) in lung adenocarcinoma.In lung adenocarcinoma,the expression of TDG was notably elevated in the tumor tissue compared with that in adjacent normal tissue (P<0.001).Male patients exhibited higher levels of TDG expression than female patients (P=0.002),and smokers demonstrated higher TDG expression than non-smokers (P<0.001).Furthermore,TDG expression was correlated with smoking cessation duration (P=0.014).Positive correlations were observed for TDG expression with both clinical T stage (P=0.003) and distant metastasis (P=0.012),while a negative correlation was found with patient prognosis (P=0.030).Furthermore,TDG emerged as an independent prognostic factor for lung adenocarcinoma.In vitro experiments revealed that silencing TDG inhibited the proliferation and migration of lung adenocarcinoma cells (both P<0.05).A correlation analysis between TDG-related genes and target kinases revealed that in lung adenocarcinoma,genes encoding aurora kinase A,cyclin-dependent kinase 2 and other enzymes exhibited positive correlations with TDG expression (all P<0.001).Furthermore,TDG expression demonstrated positive correlations with functional states including the cell cycle,DNA damage,and DNA repair processes (all P<0.001).In addition,the expression of TDG was correlated with the efficacy of treatment in the first course in clinical patients (P=0.007).Specifically,TDG expression levels were higher in the progressive disease group than in the stable disease group (P=0.016),and lower in the complete remission group than in the progressive disease group (P<0.001).Additionally,elevated TDG expression was associated with enhanced resistance to oxaliplatin (P<0.001),carmustine (P<0.001),and olaparib (P=0.004). Conclusion TDG serves as a potential prognostic biomarker,an immunotherapeutic target,and a oncogene in pan-cancer,with particular significance in lung adenocarcinoma.

DNA Copy Number Profiling in Extracellular Vesicles as Clinical Biomarkers of High-Grade Serous Ovarian Carcinoma. (PubMed, J Extracell Vesicles)
An equation based on five genes (ARID1A, NOTCH3, CSMD3, ELP4, and BARD1) showed strong predictive performance for olaparib response (area under the curve = 0.91). Collectively, these findings indicate that the CNV status of EV-DNA may serve as a non-invasive companion biomarker for patient stratification and therapeutic monitoring in HGSOC.

Targeting Chemo-resistance Mechanisms In Triple-negative Breast Cancer: A Review. (PubMed, Mini Rev Med Chem)
Particular emphasis is placed on the emerging role of natural products and compounds derived from traditional Chinese medicine, which exhibit promising preclinical activity in reversing resistance through modulation of efflux transporters, reactivation of apoptotic pathways, and inhibition of EMT. By integrating mechanistic understanding with novel therapeutic developments, this review provides a comprehensive outlook on strategies to enhance treatment durability and improve longterm clinical outcomes in TNBC.

A randomized, open-label phase II non-inferiority study of niraparib maintenance after 3 versus 6 cycles of platinum-based chemotherapy in patients with completely debulked advanced HRD-positive high-grade ovarian cancer in first-line therapy (N-PLUS/NOGGO-ov53/ENGOT-ov62). (PubMed, Int J Gynecol Cancer)
This trial aims to provide high-quality evidence on whether a reduced number of chemotherapy cycles in the era of niraparib maintenance for 3 years can safely maintain efficacy while minimizing treatment-related toxicity and improving patients' quality of life.

Decoding the Genetic Hallmarks of Breast Cancer: Molecular Signatures, Prognostic and Therapeutic Perspectives. (PubMed, Appl Biochem Biotechnol)
Current FDA approved drugs and drugs in clinical trials targeted toward the genetic influences of breast cancer include those such as Talazoparib and Margetuximab. Additionally, risk assessment and genetic screening methods are incredibly important to inform patients of their individual risk for breast cancer development. Advancements in understanding of gene specific mechanism and their correlation with breast cancer pathogenesis may provide efficient strategies for precision medicine and enhancing clinical outcomes in breast cancer patients.

Dual inhibition of PARP and ATR induces synthetic lethal vulnerability in prostate cancer with CDK12 deficiency. (PubMed, Mol Cancer Ther)
In patient-derived xenograft models harboring CDK12 alterations, combined PARP and ATR inhibition led to enhanced DSB accumulation and selectively suppressed tumor growth in CDK12-defective models. These findings highlight the importance of interrogating individual genes within the HRR pathway to define distinct mechanistic vulnerabilities and provide a strong rationale for combined PARP and ATR inhibition as a novel therapeutic strategy for patients with CDK12-altered prostate cancer.
