Figure 2. HUVECs express PNPLA2 and recombinant human PEDF does not influence viability.

Figure 2

(A) RT-PCR analysis revealed the presence of a PEDF receptor (PNPLA2) mRNA and a specific PNPLA2 antibody detected PNPLA2 protein expression in HUVECs. (B) The results of a viability assay based on the levels of ATP indicate that PEDF (10 nM and 100 nM) does not influence the ATP concentration within 24 h, whereas the positive control, 1 nM Staurosporin (SP) significantly reduced viability. Number of replicates is n = 6. One-way ANOVA, p < 0.05 (a versus b). Bars are means +/− SEM.
