S6K can be a downstream effector of the PI3K/Akt/mTOR route, and its kinase exercise regulates liver X receptor a activation and subsequent lipogenic gene expression induced by SREBP1. When HepG2 cells were treated with BA at concentrations of up to 40 mM, the phosphorylation of mTOR and S6K was paid off, these results were reversed in the presence of compound C, showing that BA inhibits hepatic steatosis by inhibiting the pathway. When three purchase FK228 week previous SD rats were fed HFD for 3 weeks, the protein levels of CAMKK and AMPK were decreased, the mRNA expression levels of SREBP1 and its objectives were enhanced, and mRNA expression levels of PPARa and CD36 were decreased when compared to those of regular diet fed rats. We examined the protein or mRNA expression of these compounds after therapy with 20 or 40 mM BA for 24 h, to enhance these data, which indicate the presence of hepatic steatosis. The protein amounts of CAMKK and AMPK were increased and the phosphorylation of mTOR and S6K decreased in a dependent manner upon BA treatment. The expression patterns of lipogenesis and lipolysis associated genes were quite similar to those seen in HepG2 cells treated without or with inhibitors of CAMKK and AMPK. Next, we examined the effect of BA on SREBP1 activity, which will be marked by cleavage into the active form and translocation into nucleus, in primary rat hepatocytes. Plastid As shown in Fig. 5D, SREBP1 activity was enhanced in hepatocytes isolated from rats fed a HFD when compared with that of regular diet fed rats. When primary hepatocytes were treated with 40 mM BA, SREBP1 activity was markedly decreased, this result was reversed in the presence of the CAMKK or AMPK inhibitor. Once again, these data indicate that BA suppresses hepatic fat accumulation modulation of the CAMKK?AMPK? mTOR?S6K?SREBP1 signaling pathway. Eight week previous ICR mice were fed HFD and/or BA for 3 weeks, after which they were sacrificed and their liver cells removed. Liver protein and mRNA were extracted to examine levels of S6K, AMPK, ACC, mTOR, CAMKK, SREBP1, PPARa and CD36. CAMKK, AMPK and ACC were amount dependently phosphory lated within the liver tissues of Pemirolast BA treated rats, mimicking the results observed. To determine the practical consequences of AMPK service, the mRNA expression of key target proteins was assessed by real-time PCR and RT PCR. The expression of lipogenic genes was substantially improved in the HFD control group when comparing to rats fed a RD, whereas BA therapy notably reduced the expression of of the genes in a dose dependent fashion. On the other hand, the mRNA expression levels of PPARa and CD36 were slightly decreased in the HFD control mice when compared with RD control mice, and BA treatment increased the expression of these genes.
