INSR and Insulin resistance: SIRT5 correlated negatively with the adiposity variables (including BMI, body fat percentage, subcutaneous adipose tissue volume, intra-abdominal fat volume, liver fat percentage, plasma leptin, and the average adipocyte diameter) and correlated positively with measures of insulin sensitivity variables (including the homeostatic model of assessment of insulin resistance [HOMA-IR], insulin receptor [INSR] gene expression, and IRS2 gene expression).
