MAGI1 acts as a tumor suppressor in estrogen receptor-positive (ER+) breast cancer (BC), and its loss correlates with more aggressive phenotype. To identify the pathways events affected by loss, we deleted gene ER+ MCF7 BC cell line performed RNA sequencing functional experiments vitro. Transcriptome analyses revealed sets biological processes related to signaling, cycle, DNA damage responses loss. Upon exposure TNF-α/IFN-γ, KO cells entered deeper level of quiescence/senescence compared control activated AKT MAPK signaling pathways. exposed ionizing radiations or cisplatin had reduced expression repair proteins showed increased sensitivity towards PARP1 inhibition using olaparib. Treatment PI3K inhibitors (alpelisib MK-2206) restored sensitized fulvestrant. An analysis human patients’ transcriptomic data that patients low levels higher mutational burden homologous recombination deficiency. Moreover, negatively correlated PI3K/AKT which confirmed our vitro observations. Pharmacological genomic evidence indicate HDACs regulators expression.

PURPOSE Cancers with homologous recombination deficiency (HRD) can benefit from platinum salts and poly(ADP-ribose) polymerase inhibitors. Standard diagnostic tests for detecting HRD require molecular profiling, which is not universally available. METHODS We trained DeepHRD, a deep learning platform predicting hematoxylin eosin (H&E)–stained histopathological slides, using primary breast (n = 1,008) ovarian 459) cancers The Cancer Genome Atlas (TCGA). DeepHRD was compared four standard 349) 141) multiple independent data sets, including platinum-treated clinical cohorts RECIST progression-free survival (PFS), complete response (CR), overall (OS) endpoints.

Ovarian cancer (OvC) constitutes significant management challenges primarily due to its late-stage diagnosis and the development of resistance chemotherapy. The standard treatment regimen typically includes carboplatin paclitaxel, with addition poly (ADP-ribose) polymerase inhibitors for patients high-grade serous ovarian (HGSOC) harboring BRCA1/2 mutations. However, variability in responses suggests need investigate factors beyond mutations, such as DNA repair mechanisms epigenetic alterations. Notably, homologous recombination deficiency (HRD) is observed an additional 20% HGSOC cases, indicating a broader spectrum defects. Existing commercial HRD assays have certain limitations, prompting global effort develop new genomic functional tests through academic research.

Among women, there been a consistent or even increased occurrence endometrial ovarian cancers; conversely, prostate cancer remains one most diagnosed malignancies, with rise in reported cases, partly due to enhanced improved efforts. Simultaneously, landscape therapeutics undergone remarkable evolution, encompassing introduction targeted therapies significant advancements traditional chemotherapy. Modern treatments aim selectively address molecular aberrations driving cancer, minimizing adverse effects on normal cells. However, chemotherapy retains its crucial role, offering broad-spectrum approach that, despite wider range side effects, indispensable treatment various cancers, often working synergistically enhance overall efficacy. For especially DNA damage response inhibitors, such as PARP have emerged promising therapeutic avenues.
