Fig. 8. Immunoflorescence of DNA damage response proteins in 24h post-irradiation of UV-B treated HDFs. Immunofluorescence of χH₂AX (Fig. 8A), pATR (Fig. 8B), & DDB2 (Fig. 8C) showing that GA significantly down-regulated the expression of these marker proteins as compared to UV-B only, indicating that GA protects the HDFs from UV-B -irradiation induced DNA damage.
