Figure 5. The effect of loading duration and different compressive loading strains (30% and 70% static strain) on the relative level of gene expression.

Figure 5

The HSR genes: (a) HSP70, (b) HSF1, (c) HSP27, and (d) HSP90, and UPR genes: (e) GRP78, (f) GRP94, (g) ATF4, and (h) CHOP demonstrated different expression patterns for the different loading strains. Asterisks indicate statistically significant differences (p < 0.05). In each case, the mean ± 2SE fold change of gene expression was normalized to the control without loading. n = 3 (30%) and n = 6 (70%).
