Figure 3From: Intraperitoneal injection of thalidomide attenuates bone cancer pain and decreases spinal tumor necrosis factor-α expression in a mouse model Time course of spinal TNF-α changes after tumor cells innoculation to the bone. Tumor induced up-regulation of the TNF-α expression within the spinal cord. (A) Bands of Western blot of the TNF-α expression (26 KDa). β-actin is a loading control. (B) Statistical analysis of relative density of Western blot between tumor and sham mice. * P < 0.05 vs sham mice.Back to article page
