To analyze the expression of the hematopoietic inositol 5-phosphatase SHIP1 in solid human cancers, we first performed Western blot analysis of carcinoma cell lines derived from breast cancer (MDA-MB-231, MDA-MB-468, MCF-7), colorectal cancer (SW-480, CaCo2, HT-29, HCT-116, HROC-24), liver cancer (Hep3B, HepG2, Huh7) and cholangio carcinoma (EGI-1, TFK-1, SKCHA-1). The gene discussed is INPP5D; the disease is colorectal cancer.
