P38MAPK signaling pathway was closely related to cell proliferation, apoptosis, cell differentiation, cell survival, cell death, and so on. However, the regulatory mechanism of P38MAPK signaling pathway in liver regeneration (LR) was unclear. In order to further reveal the roles of P38MAPK signaling pathway in rat liver regeneration, Ingenuity Pathway Analysis (IPA) software and related data sites were used to construct P38MAPK signaling pathway, and the pathway was confirmed by relevant documents literature. The expression changes of P38MAPK signaling pathway-related gene in eight type cells were further analyzed by Rat Genome 230 2.0 Array, and the results showed that 95 genes in P38MAPK signaling pathway had significant changes. H-cluster analysis showed that hepatocyte cell (HC), pit cell (PC), oval cell (OC) and biliary epithelial cell (BEC) are clustered together; and the same as Kupffer cell (KC), sinusoidal endothelial cell (SEC), dendritic cell (DC) and hepatic stellate cell (HSC). IPA software and expression analysis systematic explorer (EASE) were applied to functional enrichment analysis, and the results showed that P38MAPK signaling pathway was mainly involved in apoptosis, cell death, cell proliferation, cell survival, cell viability, activation, cell cycle progression, necrosis, synthesis of DNA and other physical activity during LR. In conclusion, P38MAPK signaling pathway regulated various physiological activities of LR through multiple signaling pathways.
