Recent studies have reported that exogenous FABP4 inhibits myocardial cell contraction.[29] Increased plasma FABP4 levels are positively correlated with BMI and insulin resistance index, and are also associated with lipid metabolism disorders.[30] Increased FABP4 expression was observed in the myometrium of obese pregnant women, the myometrium of HFD mice, and the PA‐treated USMCs. Here, FABP4 is linked to Insulin resistance.
