Generation of Mouse for Conditional Expression of Forkhead Box A2.

ABSTRACT: Forkhead box A2 (FOXA2) is a pioneer transcription factor involved in organ development, function, and cancer. In the uterus, FOXA2 is essential for pregnancy and expressed specifically in the glands of the endometrium. Loss of FOXA2 function occurs during development of endometrial cancer in humans. The current study describes the development of a mouse model for conditional expression of mouse FOXA2. Using a system consisting of a minigene located at the Rosa26 locus, we generated a CAG-S-mFOXA2 allele in embryonic stem cells and subsequently in mice; before activation, the minigene is silent because of a floxed stop cassette inserted between the promoter and the transgene. To validate functionality, mice with the CAG-S-mFOXA2 allele were crossed with progesterone receptor (Pgr)-Cre mice
