Immunocytochemical localization for relative quantification of xenobiotics induced alteration in protein expression of CYP2E1 in SH-SY5Y and U373-MG cells.

<p>Changes in % area of expression of CYP2E1 protein in SH-SY5Y cells (<b>A</b>) and U373-MG (<b>B</b>) cells following the exposure of ethanol (12–96 h), MCP (24–96 h) and ethanol (12 h) then MCP (24–96 h) groups. Data are expressed in mean ± SE of percent area of expression in the snapped microscopic fields. A minimum of 20 microscopic fields were snapped for each group. ** = p<0.01 in comparison to respective unexposed controls; while, ## = p<0.01 in comparison to ethanol (12 h) exposure respectively. Bar indicated in figures = 50 µm.
