Alternative Lengthening of Telomere-Based Immortalization Renders H3G34R-Mutant Diffuse Hemispheric Glioma Hypersensitive to PARP Inhibitor Combination Regimens

Background Introduction Diffuse Hemispheric Glioma (DHG) is a highly aggressive and poorly prognostic high-grade glioma, particularly prevalent in children and adolescents. The H3G34R/V mutation is one of the common genetic alterations in this type of tumor, often accompanied by the inactivation of the ATRX (Alpha-Thalassemia/Mental Retardation Syn...

Patterns of Genomic Instability in Ovarian Cancer Patients

Background and Research Question Ovarian cancer, as a fatal gynecological malignancy, has become the focus of recent studies, particularly on expanding the feasibility of targeted therapies. The introduction of poly(ADP-ribose) polymerase (PARP) inhibitors has marked a groundbreaking treatment option for ovarian cancer, especially for patients with...

Patient Assessment and Therapy Planning Based on Homologous Recombination Repair Deficiency

Application of Homologous Recombination Deficiency (HRD) in Tumor Patient Assessment and Treatment Planning Background Homologous Recombination (HR) is an important mechanism for repairing DNA Double-Strand Breaks (DSBs). However, when key genes in the HR repair pathway are mutated or epigenetically inactivated, cells are unable to effectively repa...
