Figure 6. Validation of neutrophil-related hub gene MRC1 in SCM. (A) Venn diagram indicates intersection between top 10 hub genes and 804 neutrophil-related module genes. (B–D) Bar plots showing MRC1 expression levels in GSE79962, GSE44363, and GSE178554 datasets, respectively. (E) RT-PCR results illustrating significant downregulation of MRC1 expression. Significance levels are indicated (*p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001).
