Figure 3. Osteoblast- and oxidative stress-related genes in wild type and Igf1-null mice treated or not with PTHrP.
Gene expression (assessed by real time PCR) of Runx2, OC, OPG, RANKL, catalase and Gadd45 in the femur of wild type (WT) and Igf1-null mice, treated or not with PTHrP (1–36) (Nt) or osteostatin (Ost). The variation coefficient of vehicle-WT (control normalized to 1) value was consistently <30% in each case. This variation was taken into consideration for statistical analysis using Kruskall-Wallis test followed by Mann-Whitney test. Values are mean ± SEM corresponding to 2 males and 4 females for PTHrP-treated mice or 3 males and 3 females for vehicle-treated mice of each genotype, respectively. *p<0.05; **p<0.01 vs vehicle-treated WT value; #p<0.05; ##p<0.01 vs vehicle-treated Igf1-null mice.
