has shown minimal expression of L-carnitine synthesis pathway genes in human oocytes, and an absence of L-carnitine synthesis enzymes in cumulus cells (26)
Two melanocortin receptors (MC3R and MC4R) are expressed in the brain, although both have been implicated in the regulation of energy balance, MC4R has a predominant role in the regulation of food intake ( A large number of studies has shown that central administration of alpha-MSH and Melanotan II (MTII), a non-selective melanocortin 3/4 receptor agonist, strongly reduces food intake and increases energy expenditure
