Abstract

Cholangiocarcinoma (CCA) induced by liver fluke (Opisthorchis viverrini, Ov) infection is one of the most common and serious diseases in northeast Thailand. We have previously reported significant overexpression of c-AMP dependent protein kinase regulatory subunit A (PRKAR1A) mRNA in Ov and N-nitrosodimethylamine (NDMA)-induced CCA in hamsters, suggesting that PRKAR1A is strongly involved in CCA carcinogenesis. The present work aimed to elucidate whether PRKAR1A is suitable to be the potential target for inhibiting CCA cell growth. To prove this hypothesis, the RNA interference (siRNA) technique was used to determine the anti-proliferative effect of PRKAR1A gene suppression on a CCA cell line. The siRNA treatment leaded to the suppression of the PRKAR1A mRNA and protein expression resulting in the reduction of CCA cell proliferation (p < 0.01). The inhibition of PRKAR1A expression leading to reduction of CCA cell growth suggests that this molecule may be used as a drug target for CCA therapy.
