ARID2, p110α, p53, and β-catenin protein expression in hepatocellular carcinoma and clinicopathologic implications.

ARID2 (ARID2), CTNNB1 (β catenin), tumor protein 53 (p53), and PIK3CA (p110α) mutations are implicated in hepatocellular carcinoma (HCC); and previous work has contributed to thorough molecular characterization of these events. However, studies that assess the impact of these mutations on downstream protein expression, especially those that evaluate all 4 cancer markers simultaneously, are relatively lacking. Hence, the present study uses immunohistochemistry to assess protein expression patterns of ARID2, β-catenin, p53, and p110α in HCCs and adjacent nonneoplastic cirrhotic tissues from 58 explanted livers.

AT-rich interactive domain 2, p110α, p53, and β-catenin protein expression in hepatocellular carcinoma and clinicopathologic implications.

AT-rich interactive domain 2 (ARID2), catenin (cadherin-associated protein), beta 1, 88kDa (β-catenin), tumor protein 53 (p53), and phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (p110α) mutations are implicated in hepatocellular carcinoma (HCC); and previous work has contributed to thorough molecular characterization of these events. However, studies that assess the impact of these mutations on downstream protein expression, especially those that evaluate all 4 cancer markers simultaneously, are relatively lacking.
