We found a large amount of COL1A1 accumulation in the liver tissue of the MCD model group compared with the MCS group, while the distribution of COL1A1 was significantly reduced in the GER group, indicating that GER was able to reduce the expression of COL1A1 in liver fibrosis and reduce the deposition of collagen in fibrotic tissue (Figures 6C–E). The gene discussed is COL1A1; the disease is Hepatic fibrosis.
