Pearson correlation analysis revealed that AFAP1L1 was negatively correlated with epithelial markers (E-cadherin, EPCAM) and positively correlated with mesenchymal markers (vimentin, N-cadherin), strongly suggesting AFAP1L1 is associated with EMT of GC cells (Fig. 4A). The gene discussed is AFAP1L1; the disease is gastric cancer.
