FIG. 6.

Inactivation of UBC4-testis does not affect the rate of testicular involution in response to cryptorchidism. Wild-type (WT) or knockout (KO) mice were subjected to unilateral surgical cryptorchidism in which one of the testes was sutured to a lower rib. At the indicated times, mice were killed, and the cryptorchid and normal testis were isolated and weighed. The ratios of cryptorchid to normal testis weights ± the SE were plotted. There were no significant differences between the wild-type and knockout animals.
