PTPRH and non-small cell lung carcinoma: First, by performing RT‒PCR and western blotting of the A549, H1299, H292, PC9, Calu-1, H460, and HCC827 NSCLC cell lines and the HBE human bronchial epithelial cell line, we found that PTPRH was highly expressed to varying degrees in NSCLC cell lines (Fig. 3A, B).
