GRK5 and non-small cell lung carcinoma: To examine whether GRK5 is also highly expressed in NSCLC cancerous cells, we analyzed the relative mRNA and protein expressions of GRK5 in normal human bronchial epithelium cell line (BEAS-2B) and NSCLC cancerous cell lines (GLC-82, SPC-A-1, H520, H838, H358, A549, and H1299).
