Western blot assays (Figures 1G–H) showed that hnRNPA1 depletion inhibited the expression of E-cadherin (Figure 1I) and promoted the expression of N-cadherin (Figure 1J) and Vimentin (Figure 1K), which suggested that hnRNPA1 might promote tumor metastasis by accelerating the transition of mesenchymal phenotypic in NSCLC. This evidence concerns the gene CDH2 and non-small cell lung carcinoma.
