摘要	Growth arrest and DNA damage-inducible 45 beta (GADD45 beta) belongs to the GADD45 family which is small acidic proteins in response to cellular stress. GADD45 beta has already been reported to have excellent capabilities against cancer, innate immunity and neurological diseases. However, there is little information regard GADD45 beta and non-alcoholic fatty liver disease (NAFLD). In the current work, we found that the expression of GADD45 beta was markedly decreased in the livers of NAFLD patients via analyzing Gene Expression Omnibus (GEO) dataset and in mouse model through detecting its mRNA in high-fat-high-fructose diet (HFHFr)-fed mice. Moreover, the results from in vivo experiment demonstrated that overexpression of GADD45 beta by AAV8-mediated gene transfer in HFHFr-fed mouse model could reduce the level of serum and hepatic triglyceride (TG), and alleviate insulin resistance. Subsequently, by combining immunoprecipitation (IP) and mass spectrometry, we identified that HSP72 directly interacted with GADD45 beta to prevent GADD45 beta from being degraded by the proteasome pathway. Finally, the benefits of GADD45 beta in regulating key factors of TG synthesis and insulin signaling pathway were abolished after HSP72 knockdown. In conclusion, GADD45 beta stabilized by the interaction with HSP72 could alleviate the NAFLD-related pathologies, suggested it might be a potential target for the treatment of NAFLD.
