Catalase is the main regulator of hydrogen peroxide metabolism. In vitiligo patients there are conflicting data on its activity and no data on the effect of −262C>T polymorphism in the catalase gene. Blood catalase activity, −262C>T polymorphism and acatalasemia mutations were examined in 75 vitiligo patients and in 162 controls, in Hungary. We measured(More)
Poly(ADP‑ribose) polymerase (PARP)‑1 is a pro‑inflammatory protein. The inhibition of PARP‑1 reduces the activity of numerous pro‑inflammatory transcription factors, which results in the reduced production of pro‑inflammatory cytokines, chemokines, matrix metalloproteinases and inducible nitric oxide synthase, culminating in reduced inflammation of the skin(More)
Major biological effects of UVB are attributed to cyclobutane pyrimidine dimers (CPDs), the most common photolesions formed on DNA. To investigate the contribution of CPDs to UVB-induced changes of gene expression, a model system was established by transfecting keratinocytes with pseudouridine-modified mRNA (Ψ-mRNA) encoding CPD-photolyase.
