Project description:Progesterone receptor (PR) is expressed from a single gene as two isoforms, PRA and PRB. In normal breast human tissue, PRA and PRB are expressed in equimolar ratios, but isoform ratio is altered during malignant progression, usually leading to high PRA:PRB ratios. We took advantage of a transgenic mouse model where PRA isoform is predominant (PRA transgenics) and identified the key transcriptional events and associated pathways underlying the preneoplastic phenotype in mammary glands of PRA transgenics as compared with normal wild-type littermates.
Project description:gene expression at 6h of differentiation of Human endometrial stromal cell expressing either or both of PRA and PRB Endogenous PGR expression is silenced with siRNA mediated knockdown. Then, cells are transduced with adenovirus exressing flag tagged PRA or flag tagged PRB. Human endometrial stromal cell expressing one or both isoforms are treated with differentiation cocktail for 6h.
