Apoptosis of abnormal oocytes is essential for defective oocyte elimination during prepubertal ovary development, and the ubiquitin system regulates the cell apoptosis via the degradation of specific proteins. Ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1) is a component of the ubiquitin system, and the UCH-L1-dependent apoptosis is important for spermatogenesis. In the present study, the change in the number of follicles and the expression of UCH-L1 in oocytes were determined in prepubertal mouse ovaries by immunohistochemical techniques. A significant decrease in the follicular pool was found in prepubertal mouse ovaries during the period of day 21 to day 28 after birth, and accordingly, the UCH-L1 protein expression was increased, to some degree in association with Jun activation domain-binding protein 1 (Jab1) and cyclin-dependent kinase inhibitor p27(Kipl). The increased UCH-L1 protein, together with the corresponding changes of Jab1 was detected in morphologically abnormal oocytes of prepubertal ovaries. Through the immunofluorescent colocalization, UCH-L1 was shown concentrating in abnormal oocytes, and a parallel change in Jab1 was also seen. The affinity analysis confirmed the interaction between UCH-L1 and Jab1 in ovaries. These results suggest that UCH-L1 plays an important role, possibly in association with Jab1 and p27(Kipl), in selective elimination of abnormal oocytes during mouse prepubertal development.

Objective To investigate the effects of Ganlu Xiaodu Pills and its residues on PSGL-1 and proinflammatory cytokines in Coxsackie virus A16 (CoxA16) mouse model; To discuss its antiviral mechanism of action. Methods Totally 150 ICR mice at age of 7 days were randomly divided into normal group, model group, all-side group, aromatic residual group, clearing residual group and removing residual group, with 25 mice in each group. Except for normal group, other groups were injected intraperitoneally with 20 μL of 107TCID50 CoxA16 standard stock solution to establish models. Except for normal group and model group, other groups were given relevant medicine for intervention. The expressions of PSGL-1, TNF-α, IL-1β and IL-4 and histopathological observation were detected after 10 days of medication. Results Except for the normal group, the existence of a large number of CoxA16 in other groups of mouse muscle tissues proved successful modeling. HE staining showed that Ganlu Xiaodu Pills and residual could reduce damage to the muscle by CoxA16 virus. Compared with the normal group, the expression of PSGL-1 protein in the model group increased (P<0.01); compared with the model group, all-side group, aromatic residue group, clearing residual group, removing residual group inhibited the expression of PSGL-1 protein, reduced the inflammatory factors of TNF-α, IL-1β, and IL-4 (P<0.01). Conclusion Ganlu Xiaodu Pills and its residues have anti-inflammatory effects, and the all-side group shows the best efficacy.
