AIM To investigate the effect of allicin on the regulation of VEGF mRNA expression in human hepatocellular carcinoma cells. METHODS Hepatocellular carcinoma cells were treated with the concentration 10 ?g?L -1 allicin in culture medium,and then the relative VEGF mRNA level at 8 h in human hepatocellular carcinoma cells was evaluated by reverse transcriptase polymerase chain reaction using HPRT(hypoxanthine phosphoribosyltransferase)as an internal control standard. RESULTS The expression of VEGF gene mRNA was inhibited obviously by allicin. Compared with control group, the relative expression level of VEGF gene mRNA was decreased by about 66 36%( P

AIM: To analyze the polymorphic expression of UDP-glucuronosyltransferase UGT1A gene locus in human colorectal epithelium. METHODS: Colorectal tissue samples were obtained from 40 patients with colorectal cancer and 20 normal controls. The levels of UGT1A transcriptions were detected by RT-PCR, exon-1 specific RT-PCR. UGT1A proteins were measured by Western blotting analysis. RESULTS: (1) UGT1A mRNA expression was found to be significantly down-regulated in colorectal cancer tissue as compared with the surrounding healthy tissues (P
