Expression of xCT mRNA in thymus, spleen and lung of the mice injected with lethal dose of LPS by Northern blot analysis. Mice were intraperitoneally injected with saline, 0.5, or 160 mg/kg LPS, and the tissues were isolated 5 h after administration. Total RNA was extracted and Northern blot analysis was performed using DIG-labeled RNA probes.
