Impaired lipid metabolism with excess release of FA from adipose
tissue leads to overspill of circulating lipids and thus to
ectopic nonadipose lipid accumulation in the liver hepatocellular lipids (HCL), muscle intramyocellular lipids (IMCL), and myocard myocardial lipids (MYCL) with detrimental consequences of lipotoxicity.
Understanding the conditions that cause these cells to go off to different fates may have a bearing on health problems such as
ectopic pregnancy, which occurs when the embryo develops outside of the womb in about 1 of 60 pregnancies, or molar pregnancy, which is abnormal

tissue and in and around the internal organs, e.g. the liver, pancreas, and heart.
It is now well established that the adipocyte - derived hormone leptin, which is well known for its central role in body weight regulation in part via its control over thermogenesis, 52 — 55 also plays an important role in blood glucose homeostasis and in the protection of insulin - sensitive
tissues against excessive
ectopic lipid storage by regulating the partitioning of fatty acid away from storage towards oxidation.
