Objective To explore the effect of recombinant human growth hormone( rh GH) on the growth of human gastric cancer MGC803 cells. Methods Western blot was performed to detect the expressions of growth hormone receptor( GHR) protein of MGC803 and MKN45 cells,and the relative expressions of GHR mRNA of the two kinds of gastric cancer cells were evaluated by qRT-PCR. Under the condition of serum starvation for 24 hours and incubated in culture media with 3% FBS,MTT assay was used to detect the proliferation of M...
