Figure 6From: HIV-TAT mediated protein transduction of Cu/Zn-superoxide dismutase-1 (SOD1) protects skin cells from ionizing radiationTAT-SOD 1 decreased ROS production induced by radiation. HaCaT cells were pretreated with PBS, SOD1 or TAT-SOD1 prior to irradiation. (A) The representative fluorescence images of ROS levels in HaCaT cells 24Â h after exposure to 20Â Gy ionizing radiation. (B) Quantitative analysis of ROS levels using Image J (MD, USA).Back to article page
