GAPDH and familial pancreatic carcinoma: Further evidence for this inhibition was obtained by Western blot analyses (Fig. 1b), which were used to compare the levels of phosphorylated Fibroblast Growth Factor Receptor (pFGFR) in two different pancreatic cancer cell lines (HPAF-II and AsPC-1) using glyceraldehyde-3-phosphate dehydrogenase (GAPDH) to normalise protein content.
