Lipid exposure induces oxidative stress in HaCaT cells. (a) Heat map showing the Pearson correlation among variables. The positive values in red, negative in yellow. It ranges from − 0.5 to 1, − 0.5 means a perfect negative linear relationship between variables, 1 indicates a perfect positive linear relationship between variables and 0 indicates that there is no relationship between studied variables. DSG1 Abs, Desmoglein1 antibodies; DSG3 Abs, Desmoglein3 antibodies. (b) The cell culture media from HaCaT cells treated with healthy control serum and 20% PV serum were subjected to measurements of SOD, CAT, Thiols, and MDA release. Results were representative of at least three independent experiments. Error bars represented standard error of the mean (s.e.m). Student’s t test, *P < 0.05, **P < 0.01, ***P < 0.001.
