Figure Lengend Snippet: Diabetic patient vSMCs exhibit DNA damage and low SIRT1 expression. ( A ) Double stranded DNA breaks were assessed via the comet assay in control ( n = 6) and diabetic (DM) ( n = 6) vSMCs. Tail moment and tail DNA percentage were calculated via CASPLab. Scale bar = 20μm. ( B ) Telomere length of control ( n = 6) and DM ( n = 6) vSMCs was quantified via qPCR and normalised to Col3a1 and Col6a1. ( C ) p21 ( n = 6) ( D ) p53, ( n = 6) ( E ) ATM ( n = 6) and ( F ) SIRT1 ( n = 6) mRNA expression from DM vSMCs was compared to controls via qPCR. ( G ) SIRT1 protein expression within DM and control vSMCs was assessed by western blot analysis and normalized to α-tubulin ( n = 6). A Mann–Whitney U test was performed. * P < 0.05, ** P < 0.01, *** P < 0.001.
