Protection Effect of Endomorphins on Advanced Glycation End Products Induced Injury in Endothelial Cells

Figure 6

Effect of EM1, EM2 on ET-1 secretion determined by ELISA test in HUVEC (a). HUVECs were incubated according to the aforementioned grouping. Each value represents the mean ± SD (𝑛=3); mRNA expression level of ET-1 after treatment with AGEs-BSA and EM1 or EM2, using BSA treated cells as reference control (b). The parameter Ct was derived for each cDNA sample and primer pair; for a given sample, Ct values for β-actin were subtracted from the Ct of each candidate gene reaction to arrive at a ΔCt value. The mean ΔCt from all control reactions was then subtracted from the ΔCt of each treated sample to arrive at ΔΔCt. The relative fold change was calculated by the expression 2^−ΔΔCt. Each data is expressed as mean ± SD (𝑛=3). ^∗𝑃<0.05,^∗∗𝑃<0.005 versus AGEs-BSA group, ^#𝑃<0.05,^##𝑃<0.005 versus control (BSA) group.
