OBJECTIVE To investigate the effects of medicated serum of Siwutang on autophagy of ovarian granulosa cells （KGN cells） in polycystic ovarian syndrome （PCOS） and its underlying mechanism. METHODS Blank serum and different- concentration medicated serum of Siwutang were prepared by intragastric administration of normal saline and different doses of Siwutang [0.52， 1.04， 2.08 g/（kg·d）] in 3-month-old female SD rats. After screening the intervention concentration of Siwutang medicated serum， KGN cells were divided into control group （without any treatment）， dehydroepiandrosterone （DHEA） group （treated with 50 μmol/L DHEA for 48 h）， blank serum group （treated with 50 μmol/L DHEA for 48 h and with 10% blank serum for 72 h） and medium-concentration of Siwutang medicated serum group （treated with 50 μmol/L DHEA for 48 h and with 10% medium-concentration Siwutang medicated serum for 72 h）. The number of autophagosomes was observed in each group， and protein expressions of pathway-related proteins [fructose-1， 6-bisphosphatase 1 （FBP1），mammalian target of rapamycin （mTOR）， phosphorylated mTOR （p-mTOR）]， autophagy-related proteins [p62， microtubule-associated protein 1 light chain 3 （LC3）] and mRNA expression of FBP1 were also detected. The （transfected） cells were further divided into Siwutang group （treated with 10% medium dose of Siwutang medicated serum for 72 h after 48 h intervention with 50 μmol/L DHEA）， Siwutang+si-NC group [negative control small interfering RNA （siRNA） transfected cells treated with 50 μmol/L DHEA for 48 h， and then with 10% medium-concentration of Siwutang medicated serum for 72 h] and Siwutang+si-FBP1 group （FBP1 siRNA transfected cells treated with 50 μmol/L DHEA for 48 h， and then with 10% medium-concentration Siwutang medicated serum for 72 h）. The effects of knocking down FBP1 on the above-mentioned effects of Siwutang were detected. RESULTS Compared with control group， DHEA group exhibited an increase in the number of autophagosomes， an elevated LC3-Ⅱ/LC3-Ⅰ and p-mTOR/mTOR， as well as increases in protein and mRNA expressions of FBP1， and decreased protein expression of p62 （P＜0.05）. Compared to both DHEA group and blank serum group， the medium-concentration of Siwutang medicated serum group showed a decrease in the number of autophagosomes， a decrease in LC3-Ⅱ/LC3-Ⅰ， and increases in p-mTOR/mTOR， protein expression of p62， protein and mRNA expressions of FBP1 （P＜0.05）. After knocking down FBP1， compared with Siwutang+si-NC group， Siwutang+si-FBP1 group showed a significant decrease in cell viability， protein expression of p62 ， protein and mRNA expressions of FBP1 as well as p-mTOR/mTOR， and an increase in LC3-Ⅱ/LC3-Ⅰ （P＜0.05）. CONCLUSIONS Siwutang can promote the phosphorylation of mTOR protein by up- regulating the protein and mRNA expressions of FBP1 in KGN cells， thus inhibiting autophagy of KGN cells.

【Objective】 To explore the expression of USP9X in platelets and its effect on platelet function. 【Methods】 The expression of USP9X in human and mouse was evaluated by PCR and Western blot. Platelets from young and old mice were separated and prepared, and the expression of USP9X was detected. USP9X inhibitos were used to assess the regulation of USP9X in platelet function, including aggregation, ATP release and spreading. Platelet lysates were collected in different time points to evaluate the change of phosphorylation of Akt in USP9X inhibitors treated platelets. 【Results】 Both human and mouse platelets expressed USP9X. Compared to the young mice, the old mice showed significantly enhanced expression of USP9X(P<0.05). To assess the effect of USP9X on platelet function, USP9X inhibitor was used to pre-incubate platelets for 30 min and platelet function were examined later. Results showed that USP9X inhibitor significantly decreased platelet activation including aggregation, ATP release and spreading(P<0.05). Compared to the control group, the inhibitor treated group showed a significant decrease in the spreading area after 45 minutes. The Western blot results showed a significant decrease in Akt phosphorylation levels of platelets in the USP9X inhibitor treated group. 【Conclusion】 Both human and mouse platelet express USP9X, and inhibition of USP9X decreased platelet function including aggregation, ATP release and spreading. USP9X can also influence the phosphorylation of Akt. The inhibitor of USP9X may become a potential therapeutic target for thrombosis intervention.
