Figure 5. Antioxidants abrogate laser-induced NF-kB activation in MEF but not ATP increase.
(A) NF-kB measured 6 hours post irradiation of cells incubated 2 hours with 1 mM N-acetyl cysteine or 100 µM ascorbic acid. (B) ATP measured after 2-hour incubation with 1 mM N-acetyl cysteine. * p<0.05; ** p<0.01 compared to control.
