Figure 2. Adrenomedullin_22–52 inhibited HREC proliferation induced by high glucose. After the HRECs were treated with high glucose or high glucose plus different concentrations of adrenomedullin_22–52 for 24 h, cell proliferation was measured by CCK-8 assay. The absorbance value was detected using an enzyme-linked immunity instrument at a wavelength of 450 nm. All values represent Mean±SD (n=3). * p<0.05 versus the 30 mM group.
