a: Expression of osteoblastic gene markers
For each group, plot mRNA levels relative to the housekeeping gene (GAPDH). Error bars are from +/− the SEM about the mean delta Ct.
Horizontal brackets indicate p <= 0.05 for the comparison of mRNA values (relative to GAPDH) between the two groups pointed to by the ends of each bracket.
Young normal glucose tolerant (NGTY); post-menopausal normal glucose tolerant (NGT); post-menopausal impaired glucose tolerant (IGT); post-menopausal type 2 diabetes mellitus (T2DM); osteocalcin (OC); runt-related transcription factor 2 (RUNX2); collagen type I alpha 1 chain (COL1A1)
