Progesterone promotes the proliferation and migration of cultured breast cancer cells / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of progesterone on the growth and migration of breast cancer cells.</p><p><b>METHODS</b>MCF-7 and T-47D cells were cultured in DMEM and stimulated with 100 nmol/L progesterone for 48 h, and the cell proliferation was evaluated by MTT assay, cell migration by wound-healing assay and E-catherin expression by Western blotting.</p><p><b>RESULTS</b>Progesterone stimulated the cell proliferation and migration and down-regulated the expression of E-catherin in both MCF-7 and T-47D cells.</p><p><b>CONCLUSIONS</b>Progesterone stimulates the cell proliferation and migration of cultured breast cancer cells, suggesting the clinical significance of anti-progesterone therapy in breast cancer.</p>
