Gene expression in response to progestin R5020


ABSTRACT: Breast cancer cell lines containing the progesterone receptor respond to progestins, altering expression of a subset of genes. In a previously published experiment of inducible knock-down of histone H1 isoforms with an shRNA-expression lentivector (GSE12299), we modified the breast cancer cell line T47D with different vectors. Here, we explored response to progestin R5020 of control cells generated with the empty shRNA-expression vector. Stable breast cancer-derived cell lines containing the empty vector for inducible shRNA expression were grown for two days in the absence of serum. Progestin R5020 or vehicle was added for 6 hours, in duplicate, and RNA was extracted for microarray hybridization.

PFKFB (6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase) catalyses the synthesis and degradation of Fru-2,6-P2 (fructose-2,6-bisphosphate), a key modulator of glycolysis and gluconeogenesis. The PFKFB3 gene is extensively involved in cell proliferation owing to its key role in carbohydrate metabolism. In the present study we analyse its mechanism of regulation by progestins in breast cancer cells. We report that exposure of T47D cells to synthetic progestins (ORG2058 or norgestrel) leads to  ...[more]
