FKBP5 and ovarian carcinoma: In fetal ovaries, exposure to dexamethasone increased FKBP5 (Poulain et al., 2012), and overexpression of FKBP5 was associated with chemoresistance in ovarian cancer cells (Sun et al., 2014), suggesting that ovarian FKBP5 is involved in the ovarian response to xenobiotic exposure.
