Abstract: Objective To explore the expression of vitamin D receptor(VDR) in cancerous tissues of patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Methods The relative levels of VDR mRNA in liver tissues was detected by real-time PCR. VDR expression were determined by immunohistochemical method, and the relative expression of VDR protein was detected by Western blot. Results Immunohistochemistry showed that cancerous tissues, para-cancerous tissues, normal liver tissues expressed VDR equally. VDR was mainly expressed in the cytoplasm, and there was almost no expression in the nucleus. The RT-PCR detection showed that VDR mRNA in cancerous tissues was(2.77±0.30), significantly higher than that in the para- cancerous tissues(1.62±0.21) or normal liver tissues[(1.57±0.19), P<0.01];Western blot showed that the expression of VDR protein in cancerous tissues was(1.15±0.57), significantly higher than that in the para- cancerous tissues(1.02±0.25) or in normal liver tissues[(0.37±0.11), P<0.01]. Conclusion VDR is closely related to the development of hepatocellular carcinoma
