LncRNA BCRT1 depletion suppresses cervical cancer cell growth via sponging miR-432-5p/CCR7 axis.

UNLABELLED

Breast cancer-related transcript 1 (BCRT1), a lncRNA that is overexpressed in several human cancers, facilitates the progression of breast cancer and osteosarcoma. Nevertheless, the function of BCRT1 in cervical cancer (CC) still remains unknown. In this study, BCRT1 was significantly overexpressed in CC tissues and correlated with the advanced stage of CC patients. BCRT1 depletion dampened CC cell proliferation, and drives cell apoptosis and cell cycle inhibition. Mechanistically, BCRT1 bound miR-432-5p and negatively modulated miR-432-5p's expression in CC cells. Reduced miR-452-3p expression was observed in CC tissues and exerted tumor suppressive function in CC cell growth. Further mechanism study revealed that CCR7 was clarified as a target of miR-432-5p and was inhibited following BCRT1 depletion. CCR7 transfection could recover CC cell growth that was suppressed with BCRT1 down-regulation. These results revealed the novel function of BCRT1/miR-432-5p/CCR7 pathway in CC, suggesting BCRT1 might be a potential biomarker and target for CC treatment.
