XBP1 and metabolic dysfunction-associated steatohepatitis: It was found that the gut microbiota of FFC-fed mice was completely separated from that of CD-fed mice (p = 0.001), but the gut microbiota of the FFC-fed mice was not completely separated from the FT@XBP1 treatment group, suggesting that FT@XBP1 treatment could partially restore the composition of the intestinal microbiota in NASH mice.
