Figure 3From: EGFR phosphorylates and inhibits lung tumor suppressor GPRC5A in lung cancerEndogenous EGFR in NSCLC cells induces tyrosine phosphorylation on GPRC5A. A, Western blot of eleven NSCLC cell lines was performed with anti-GPRC5A, anti-EGFR, anti-HER-2, and anti-actin, as indicated. B, H292G Cells were serum-starved for 24Â hours, then treated with or without EGF (100Â ng/ml) for 5Â min. Cell lysates were harvested for IP-Western using either anti-GPRC5A or normal IgG. Western blot was performed using either PY99 antibody or anti-GPRC5A as indicated. C. H1792-GPRC5A, D, H1792-V, H1792-5A, H1792-4Â F stable transfectants were serum-starved for 24Â hours and then treated with EGF for 5Â minutes or pretreated with AG1478 (30Â ng/ml) for 6Â hours as indicated. Total cellular proteins were analyzed by IP-Western using the antibodies as indicated.Back to article page
