Expression of mucin 15 in hepatocellular carcinoma and its clinical implications / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the expression of mucin 15 (MUC15) in hepatocellular carcinoma and explore its association with the prognosis of patients.</p><p><b>METHODS</b>The expression of MUC15 was detected by quantitative RT-PCR and Western blotting in liver cell line L02, liver cancer cell lines HepG2, MHCC-97H, and SMMC-7721, and in 122 HCC and corresponding adjacent non-tumor liver tissues. The association of MUC15 expression in HCC tissues with the clinical parameters and the patients' survival was analyzed.</p><p><b>RESULTS</b>The 1iver cell line L02 showed significantly higher MUC15 expression level than the liver cancer cell lines HepG2, MHCC-97H, and SMMC-7721 (P<0.05). The expression level of MUC15 was markedly lower in the HCC tissues than in the adjacent non-tumor liver tissues (P<0.05). MUC15 expression in the HCC tissues was significantly correlated with the tumor TNM stage, intrahepatic or lymphatic metastasis, portal vein thrombosis and tumor differentiation (P<0.05). Kaplan-Meier survival analysis suggested that a low MUC15 expression was associated with a poor clinical prognosis of the patients.</p><p><b>CONCLUSION</b>The expression of MUC15 is correlated with the clinicopathological features and prognosis of HCC patients, and may potentially serve as a novel prognostic marker for HCC.</p>

Effect of Jiawei-Sini Dection on expression of transforming growth factor-β1 receptor Ⅰ、Ⅱ of hepatic fibrosis in rats / 国际中医中药杂志

Objective To investigate the role of Jiawei-sini Dection on expression of rat transforming growth factor-β1 receptor Ⅰ,Ⅱ(TβRⅠ,TβR Ⅱ), and study its treatment of anti-HF and the possible mechanisms. Methods The model of rat hepatic fibrosis was setup by subcutaneous injection of carbon tetrachloride and drinking alcohol freely;According to random block method, the successful model rats were divided into three groups:pathological model group (group B),Fufangbiejiarangan tablet group (group C), and Jiawei Sini Decoction group (group D), each group containing ten rats. Group A and group B were given two milliliters saline, group C was given Fufangbiejiarangan tablets 0.625 grams per kilogram of body weight, group D was given Jiawei Sini liquid 15.625 grams per kilogram of body weight.Each rat was fed once a day for 8 weeks.In order to avoid the natural repair of the hepatic affecting the experimental results, the rats,except group A, were still injected 40% CCl4 three milliliters per kilogram of body weight after feeding drug once a week. Fufang-Biejia-Ruangan Ttablet group was set as a positive control;The effects on expression of TβRⅠ,TβR Ⅱ were determined by immunohistochemical method. Changes of alanine aminotransferase (ALT), aspartate aminotransferase(AST),alkaline phosphatase(ALP) and TβRⅠ,TβR Ⅱ were observed in rats. Results The expression of TβRⅠ、Ⅱ, compared with the pathological model(16.63±2.69)%, (14.57±1.09)%, were significantly reduced in Jiawei-Sini Dection group[they are(8.09±0.71)%,(6.51±0.48)%, the difference was statistically significant(P＜0.05).The effects of Jiawei-Sini Dection was equal to the effect of Fufang-Biejia-Ruangan Tablets on expression of TβRⅠ,TβR Ⅱ(P＞0.05). Conclusion Jiawei-Sini Dection was able to inhibit the expression of TβRⅠ and TβR Ⅱ, thus affected the combination of TGFβ1, and their receptors.
