PELP1 and gastric cancer: To further validate PELP1 expression in GC cell lines from the CCLE and Oncomine databases (Figures 1D,E1), expression of PELP1 was assayed in the AGS cell line and other GC cell lines such as SNU-1, SNU-16 and KATOIII compared to normal gastric epithelium cell line GES-1 using Western blot (Figure 1E2).
