Cadherin Related Family Member 2 Acts As A Tumor Suppressor By Inactivating AKT In Human Hepatocellular Carcinoma.

ABSTRACT: Cadherin related family member 2 (CDHR2) belongs to the protocadherin family and is abundant in normal liver, kidney, and colon tissues, but weakly expressed in cancers arising from these tissues. In this study, we demonstrated that CDHR2 was highly expressed in para-cancer tissues of human hepatocellular carcinoma (HCC), but significantly downregulated or silenced in 85.7% (6/7) of HCC cell lines by both semi-quantitative PCR and western blot, and 79.1% (19/24) and 80.2% (89/111) of tumor tissues from patients with HCC by semi-quantitative PCR, and immunohistochemistry, respectively. Interestingly, CpG islands in the promoter of CDHR2 gene were hypermethylated in HCC cell lines and tissues compared with the para-cancer tissues by methylation-specific PCR analysis, leading to transcription
