Analysis of Blood for O-GlcNAc levels in Relation to Anthropometric Measurements. A) Analysis of whole blood comparing subjects with low (LH) and high (HH) homeostatic model assessment for insulin resistance (HOMA-IR) for global O-GlcNAcylation (O-GlcNAc), β-N-acetylglucosaminyltransferase (OGT), and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) in arbitrary units (AU). B) Quantification of global O-GlcNAc for LH and HH. C) Linear regression analysis of O-GlcNAc and HOMA-IR. D) Linear regression analysis of body fat percentage (%) and HOMA-IR. E) Linear regression analysis of O-GlcNAc and body fat percentage (%). All data represents n = 24. *Indicates p < 0.05.
