Effect of oxidative stress on GFP-LC3 dots in shcontrol BMSCs and SVCT2 knockdown BMSCs. Both cell types were
transiently transfected with GFP-LC3B expression vector and then treated with Sin-1 (600 μM), ascorbic acid (250 μM) and
combination of both for 4 h as described in material and methods. a) Representative confocal photos demonstrated that Sin-1
increase punctuate GFP-LC3B and ascorbic acid down-regulate GFP-LC3B in shcontrol BMSCs. SVCT2 knock down BMSCs showed high
level of punctuate GFP-LC3B and ascorbic acid did not nullify GFP-LC3B punctuate dots. b) Determination of the average number of
puncta, as distinct fluorescence green spots, per cell was performed. Data were analyzed by ANOVA followed by Bonferroni post hoc
test (*p b 0.05; ** p b 0.01, n = 3)
