Figure Lengend Snippet: The effect of vitamin D 3 (Vit. D 3 ), hydrogen peroxide (H 2 O 2 ), N-Acetyl-L-Cysteine (NAC), the combination of Vit. D 3 with H 2 O 2 (Vit. D 3 + H 2 O 2 ) and the combination of NAC with H 2 O 2 (NAC + H 2 O 2 ) on mRNA expression of the antioxidant enzymes ( a ) catalase (CAT), ( b ) sodium dismutase 1 (SOD1), ( c ) sodium dismutase 2 (SOD2), ( d ) sodium dismutase 3 (SOD3) and ( e ) glutathione peroxidase 3 (Gpx3) in 1.2B4 cells. The 1.2B4 cells were non-treated (C, black bars) and treated with Vit D 3 (75 nM; 100 nM, yellow bars), H 2 O 2 (400 µM, brown bars), Vit. D 3 (75 nM; 100 nM) with H 2 O 2 (400 µM, orange bars), NAC (3 mM, blue bars), NAC (3 mM) with H 2 O 2 (400 µM, violet bars) for 24, 48 and 72 h. Data are expressed as the mean ± standard deviation (SD) of the fold change of three independent experiments in relation to the untreated control. GAPDH was used as a reference gene. a p < 0.05; aa p < 0.01; aaa p < 0.001 vs. C; b p < 0.05; bb p < 0.01; bbb p < 0.001 vs. H 2 O 2 ; c p < 0.05; cc p < 0.01 vs. 75D 3 ; d p < 0.05; dd p < 0.01 vs. 100D 3 ; e p < 0.05; ee p < 0.01 vs. 75D 3 + H 2 O 2 ; f p < 0.05 vs. 100D 3 + H 2 O 2 .
Article Snippet: The reaction of reverse transcription was conducted using a High Capacity cDNA Reverse Transcription Kit (Thermofisher Scientific Inc., Waltham, MA, USA), according to the manufacturer’s protocol. cDNA was employed to run qRT-PCR by using the TaqMan assays targeting the studied genes (ID: Hs00156308_m1 for CAT, Hs00533490_m1 for SOD1, Hs00167309_m1 for SOD2, Hs00162090_m1 for SOD3, Hs00173566_m1 for Gpx3, Hs99999905_m1 for GAPDH) (Life Technologies, Carlsbad, CA, USA) and TaqMan Universal Master Mix (Life Technologies, Carlsbad, CA, USA).
