Project description:PAX2 is one of nine PAX genes that regulate tissue development and cellular differentiation in embryos. PAX2 promotes cell proliferation, oncogenic transformation, cell lineage specification, migration, and survival. In our previous study, we found that PAX2 is highly expressed in low-grade ovarian serous carcinoma, but its expression in clear cell, endometrioid, and mucinous cell ovarian carcinomas have not been studied. More importantly, the functional role of PAX2 in ovarian cancer is not known. Downregulation of PAX2 in PAX2-expressing ovarian cancer cells inhibits cell proliferation and migration. This growth inhibition is due to the upregulation of the tumor suppressor gene G0S2 and subsequent induction of apoptosis. The PAX2 pathway thus represents a potential therapeutic target for PAX2-expressing ovarian carcinomas. Knockdown PAX2 expression in these cell lines was achieved by lentiviral shRNAs targeting the PAX2 gene. PAX2 stable knockdown cells were characterized for cell proliferation, migration, apoptosis, and gene expression profiles.

Project description:<p>BRCA1 mutations are a hallmark of hereditary ovarian cancer, strongly linked to deficiencies in homologous recombination (HR) DNA repair and impaired DNA replication fork protection. However, its roles in cancer progression beyond maintaining genomic integrity remain poorly understood. Through metabolomics approaches, we found BRCA1-deficiency strikingly increased choline metabolism. Loss of BRCA1 promotes choline uptake through upregulating choline transporter-like protein 4 (CTL4). BRCA1 directly binds and recruits EZH2-mediated H3K27Me3 deposition to CTL4 promoter. CTL4 was therefore overexpressed in ovarian cancer tissues with BRCA1 mutations. Furthermore, BRCA1-deficiency significantly promotes ovarian cancer invasion, while inhibition of CTL4 reverses the high metastatic potential of BRCA1-deficient ovarian cancer cells, suggesting the functionality and specificity of CTL4 as a therapeutic target. Additionally, we discovered that phosphocholine, the choline metabolite increased by CTL4 overexpression, interacted with and stabilized the epithelial-to-mesenchymal transition inducer FAM3C in BRCA1-deficient ovarian cancer cells. Importantly, we identified a potent CTL4 inhibitor, DT-13, which significantly reduces choline metabolism and effectively suppresses metastasis in BRCA1-deficient ovarian cancers. Therefore, our study uncovers a mechanism underlying metastasis in BRCA1-deficient cancers and identifies CTL4 as a therapeutic target for metastatic ovarian cancer patients with BRCA1 mutations.</p>
