(E) The expressions of PTEN and NEDD4-1 were measured in SGC7901 cells transfected with pcDNA-CRNDE or Mock at four time-points after cycloheximide (CHX, 100 μg/mL) treatment. GAPDH was served as an internal control. Left: Representative bands. Right: Quantitative results. The results shown are from three biological replicates and are expressed as mean ± SD. Student's t-test. *P<0.05, **P<0.01 vs. Mock.
