Glutamine metabolism drives tumor aggressiveness but not chemoresistance in ovarian carcinoma cell lines.

ABSTRACT:

Background

Glutamine, an essential nutrient for healthy cells, supports immunity and cytoprotection during anticancer treatments. However, intense glutaminolysis may promote proliferation and chemoresistance in ovarian carcinomas by activating the PI3K/AKT/mTORC1 pathway and overexpressing c-Myc. This study aimed to characterize glutamine metabolism in ovarian carcinomas and assess its impact on tumor aggressiveness and chemosensitivity, to inform nutritional supplementation or therapeutic targeting.

Methods

Glutamine and glucose consumption, chemosensitivity to cisplatin and paclitaxel, and doubling time were analyzed in three ovarian carcinoma cell lines (ES-2, TOV-21G: clear cell; OVCAR-3: serous papillary) and primary ascites cells under varying glutamine concentrations
