Accumulating evidence suggests that gut microbiota plays a crucial role in the development of metabolic diseases, especially type 2 diabetes mellitus (T2DM). The nutrient-rich resource Cornus Fructus (CF) showed curative effects on diabetes mellitus. However, the mechanism underlying its hyperglycemic activity remains obscure. ⋯ Also, CF extracts could elevate the production of short-chain fatty acids, as well as regulate the composition of gut microbiota. The key bacteria related to T2DM including Firmicutes, Bacteroides, Lactobacillus, and Clostridium were modulated by metformin and CF. Altogether, CF is a potential nutrient-rich candidate that can be used in functional foods for the treatment of T2DM, and the change of gut microbiota might be a novel mechanism underlying its hyperglycemic activity.

Blockade of the NOD-like receptor protein 3 (NLRP3) inflammasome has been shown to be effective in halting the progression of non-alcoholic steatohepatitis (NASH). Antrodia cinnamomea is a well-known indigenous medicine used by Taiwanese aboriginal tribes. However, its effect on NASH remains unclear. ⋯ ACE significantly inhibited NLRP3 inflammasome activation in vitro and in vivo. In addition, ACE attenuated the severity of MCD-induced steatohepatitis, reduced the levels of oxidative stress markers, and ameliorated inflammatory responses, but restored autophagic flux. Based on these findings, Antrodia cinnamomea could be developed into an anti-non-alcoholic fatty liver disease/NASH agent.
