While comparing the expression of abdominal SAT HSD11B1 according to glucose tolerance, additional studies have shown that this expression was greater respectively in those with T2DM (1.8 ± 0.7 vs. 1.1 ± 0.4 AU; P < 0.05) [6] and those with impaired glucose tolerance (0.5 ± 0.06 vs. 0.29 ± 0.03 AU; P < 0.005) compared with normal controls [14]. Here, HSD11B1 is linked to Impaired glucose tolerance.
