Figs. 6-A through 6-F Western blot analysis of normal, uninjured nerves (N) and nerves six weeks after early and late decompression (dCNC) of a chronic nerve compression (CNC) injury. The densitometry for the markers in Fig. 6-A is plotted in the remaining panels as the mean and standard error. *P < 0.05. A.U. = arbitrary units. Fig. 6-A Western blot bands for the cellular hypoxic markers HIF1α, catalase, SOD, MMP2, and MMP9 and for the GAPDH reference. Fig. 6-B HIF1α remained elevated after early decompression but not after late decompression. Fig. 6-C MMP2 levels were unchanged after decompression. Fig. 6-D Catalase levels followed a pattern similar to HIF1α, with elevation after early decompression. Fig. 6-E MMP9 remained elevated after late decompression. Fig. 6-F SOD levels were unchanged.
