Figure 4From: Altered mRNA expression of genes related to nerve cell activity in the fracture callus of older rats: A randomized, controlled, microarray study mRNA levels of three genes related to nerve function and up-regulated more in young rats than in older rats following femoral fracture. The decline with age was significant at P < 0.001 (top graph), P < 0.02 (middle graph) and P = 0.01 (bottom graph). The data are presented as in Figure 2.Back to article page
