In NSCLC tissues, further correlation analysis also indicated a positive expression correlation between HNRNPC and PCNA (r = 0.724, P < 0.05), along with a positive expression correlation between HNRNPC and N-cadherin (r = 0.755, P < 0.05) (Fig. 3I). This evidence concerns the gene PCNA and non-small cell lung carcinoma.
