Abstract High grade serous ovarian malignancy (HGSC) is the most common and fatal type of ovarian malignancy, largely due to troubles in early diagnosis and quick metastasis throughout the NLG919 peritoneal cavity. Previous studies have NLG919 shown that expression of Notch3 correlates with worse prognosis and increased tumorigenic cell behaviors in HGSC. We investigated the mechanistic role of Notch3 in a model of metastatic ovarian malignancy using the murine ovarian surface epithelial cell collection, ID8 IP2. Notch3 was activated in ID8 IP2 cells via expression of the Notch3 intracellular domain name (Notch3IC). Notch3IC ID8 IP2 cells injected intraperitoneally caused accelerated ascites and reduced survival compared to control ID8 IP2, particularly in early stages of disease. We interrogated downstream targets of Notch3IC in ID8 IP2 cells by RNA sequencing and found significant induction of genes that encode adhesion and extracellular matrix proteins. Notch3IC ID8 IP2 showed increased expression of ITGA1 mRNA and cell-surface protein. Notch3IC-mediated increase of ITGA1 was.
