MOGAT1 and obesity due to melanocortin 4 receptor deficiency: We next sought to determine whether the results from the studies conducted in mice apply to humans by evaluating subcutaneous adipose tissue MOGAT1 expression and the relationship between adipose tissue MOGAT1 expression and basal lipolytic activity in 22 men and women with either metabolically-normal obesity (MNO, n = 10) or metabolically-abnormal obesity (MAO, n = 12) (Table 4).
