ITPR1 is expressed in a subset of carcinomas of the lung. a Quantitative Western blot analysis showing ITPR1 expression as percentage of the ITPR1 expression in normal human bronchial epithelial (NHBE) cells, in the small cell lung cancer cell line H1339 and in the non-small cell lung cancer cell line HCC. The expression of IP3R was increased with H1339 showing the highest expression (n = 4, *P < 0.01 versus all other groups). Image reproduced from Bergner et al.
