Figure 3. The GSEA pathway map was graphed. The results of GSEA manifested that the ERK pathway and other pathways were the enrichment pathways (A). The content of genes in different groups was subjected to statistical analysis. miR-212 was lowly expressed in the disease group and highly expressed in the control group (B). MAPK3 was highly expressed in the disease group (C). The results of correlation analysis revealed that MAPK3 was correlated with MMP (D) and TNFSF1 (E). GSEA, Gene Set Enrichment Analysis; ERK, extracellular-signal-regulated kinase; MAPK, mitogen-activated protein kinase; MMP, matrix metalloproteinase; TNFSF1, tumor necrosis factor ligand superfamily member 1.
