Activated HIF-1 enters the cell nucleus, where it binds to the promoters of the xanthine dehydrogenase (XDH) and 5-nucleotidase II (NT5C2) genes, thereby upregulating the expression of XDH and NT5C2
Reported pathways include TGF- signaling, antioxidant defense (superoxide dismutase, glutathione peroxidase), extracellular-matrix gene expression (collagen types I and III, decorin, perlecan), and inflammatory cytokine modulation
They invariably occur within six hours of initiation of acetylcysteine, most often within the first two hours
