The effect of abnormal vitamin A metabolism was transferable to testis. (A) The testicular vitamin A levels of the ND and HED fed groups were measured (n=6). (B) Serum vitamin A levels of the ND, MED and HED-fed groups were examined (n=6). (C) The representative images of RBP4 and RDH10 immunofluorescent (IF) staining in sections of testicular tissue. Scale bar=50 μm. (D) The IF staining for STRA8 and SYCP3 is shown together with MVH in representative sections of testicular tissue. Scale bar=25 μm. (E) Western blot of STRA8, RDH10, MVH, GAPDH and β-ACTIN in each indicated group. (F) Quantification protein levels of (a) STRA8, (b) RDH10 and (c) MVH. HED, high-energy diet; MED, medium-energy diet.
