Monocyte Proteomics Reveals Involvement of Phosphorylated HSP27 in the Pathogenesis of Osteoporosis

Figure 2

Representative MS/MS spectra with reporter ions showing differential abundance of HSPB1. Monocyte proteins from premenopausal (pre) women and postmenopausal (post) women with low versus high BMD were labelled with iTRAQ reagents 114 (pre low), 115 (pre high), 116 (post low), and 117 (post high).
