There existed significantly positive correlations in the gene expression levels of ACTB-TLN1, TLN1-MYH9, ACTB-MYH9, ACTB-FLNA, MYH9-FLNA, TLN1-FLNA in GC cases (Figure 3B–3G), while the gene expression levels of OXSM-ACTB, SLC7A11-ACTB, RAC1-TLN1, OXSM-TLN1, SCL7A11-TLN1, RAC1-FLNA, OXSM-FLNA, SLC7A11-FLNA in GC cases exhibited significantly negative correlation (Figure 3H–3O). This evidence concerns the gene RAC1 and gastric cancer.
