CRISP4 subcellular localization in the epididymis of ob/ob mice is disrupted. (a–d) CRISP4 expression (green) and 4′,6-diamidino-2-phenylindole staining (blue) in the caput epididymis of WT, ob/ob intact, ob/ob intact + leptin (2.5 μg/g IP for 7 days), and ob/ob orchidectomized + leptin (2.5 μg/g IP for 7 days) mice. (a) In WT mice, CRISP4 expression is mostly observed at the apical (luminal) membrane of the epididymal cells. (b) In ob/ob mice, CRISP4 expression is mainly observed in the base of the cells. (c) The pattern of CRISP4 expression in ob/ob mice treated with leptin is similar to that observed in WT animals. (d) Orchidectomized ob/ob mice treated with leptin show a reduced and disorganized CRISP4 expression in the ductus epididymis. Scale bar: 50 µm.
