NQO1 and systemic sclerosis: The expression of the two target genes was increased in the HOCl-SSc-control group compared to the PBS-control group: p<0.01 for NQO1 (relative expression in PBS-control group = 1 and relative expression in HOCl-SSc-control group = 20.5954) and p<0.05 for GCLC (relative expression in PBS-control group = 1 and relative expression in HOCl-SSc-control group = 6.6559).
