High expression of Rap2A is associated with poor prognosis of patients with hepatocellular carcinoma.

ABSTRACT: Rap2A is overexpressed in a multitude of human cancers and plays an important role in cytoskeleton rearrangement, arteriogenesis and cell migration. However, its role and function in hepatocellular carcinoma (HCC) has not yet been explored. Here, we aimed to investigate the expression of Rap2A in HCC and the relationship between Rap2A and clinicopathologic features of patients. Western blot and quantitative real-time PCR (qRT-PCR) showed that Rap2A was remarkably upregulated in HCC tissues compared to adjacent normal liver tissues. Immunohistochemistry (IHC) showed that Rap2A was mainly localized in the cytoplasm rather than nuclei in HCC tissues. Overexpression of Rap2A was significantly correlated with tumor size (P=0.019), metastasis (P=0.002), pathological differentiation (P=0.028) and
