  • The Expression of Growth Hormone Receptor in Human Hepatocellular Carcinoma

    ObjectiveTo explore whether the growth hormone receptor (GHR) is present in human hepatocellular carcinoma (HCC). MethodsThe GHR were measured in samples of human HCC (50 cases), the liver tissues adjacent to hepatocellular carcinoma (49 cases), cirrhotic liver tissues (30 cases) and control liver tissues (30 cases) by immunohistochemistry technique. ResultsThe GHR positive expression rate was 42.0% in samples of human hepatocellular carcinoma, and 95.9% in adjacent tissue of HCC, 96.7% in cirrhotic liver tissues, and 93.3% in normal liver tissues; the significance of the differences in the GHR positive expression rate was seen between HCC and the compared groups.ConclusionThe lower expression of GHR in HCC is present. The growth hormone administration can be used in patients of HCC with radical resection or GHR negative expression patient.

  • Expression of Growth Hormone Receptor in Human Gastric Cancer Tissue

    Objective To investigate the expression of growth hormone receptor (GHR) in human gastric cancer tissue.  Methods The GHR was detected in samples of the human gastric cancer (57 cases) and the distal normal tissues (57 cases) by immunohistochemistry technique.  Results The GHR expression positive rate was 80.7%(46/57) in the human gastric cancer tissues and 70.2%(40/57) in the distal normal tissues. There was no statistic difference between the human gastric cancer tissues and the distal normal tissues (Pgt;0.05). There were also no statistic differences among the gastric cancer tissues of different differentiation, different tissue type, different gender and different age ranges (Pgt;0.05).  Conclusion It is similar that the expression of GHR between the human gastric cancer tissues and the distal normal tissues.

  • Effect of Small Interfering RNA Targeting Inhibition of Growth Hormone Receptor on Proliferation and Invasion of Human Liver Cancer Line SMMC-7721

    ObjectiveTo investigate effect of small interfering RNA (siRNA) targeting inhibition of growth hormone receptor (GHR) on proliferation and invasion of human liver cancer line SMMC-7721. MethodsSMMC-7721 cells were transfected with siRNA targeting human GHR by GenMuteTM transfection regent.The cells were divided into three groups:blank control group (non-transfected siRNA),negative control group (transfected with non-specific siRNA),and specificity transfected group (transfected with expression specifically interfere by GHR siRNA).the relative expression of GHR mRNA was detected by using real-time PCR.the expression of GHR protein was detected by using Western blot.The cell proliferation was assessed by CCK-8 assay.And the ability of invasion was examined by Transwell assay. ResultsThe expressions of GHR mRNA and GHR protein in the specificity transfected group were significantly lower than those in the blank control group (P<0.05) and the negative control group (P<0.05).Compared with the blank control group and the negative control group,the absorbance value and the number of migrating cells of SMMC-7721 cells were decreased obviously (P<0.05) in the specificity transfected group. ConclusionsiRNA targeting human GHR could reduce capability of proliferation migration and invasion of SMMC-7721 cells.
