Article Synopsis
  • The hormone ghrelin plays a protective role in cancer-related anorexia-cachexia syndrome (CACS), with its levels rising to help combat weight loss and anorexia in cancer patients.
  • A study found that deleting ghrelin worsened body weight and fat loss in mice with cancer, while deleting LEAP2, a ghrelin antagonist, seemed to lessen the severity of CACS.
  • In human patients with CACS, a lower ratio of plasma LEAP2 to total ghrelin was associated with better weight stability, indicating a possible protective mechanism against worsening CACS.

Article Synopsis
  • This study investigates how ghrelin receptors in the olfactory bulb affect smell and eating behavior in mice.
  • Mice without these receptors showed worse smelling ability, increased anxiety, and changes in how they searched for food.
  • The findings suggest that the olfactory bulb plays a crucial role in smell and food-seeking behavior, especially when hungry, influencing metabolism and preparation for eating.

Objective: The number of individuals affected by metabolic dysfunction associated fatty liver disease [1] is on the rise, yet hormonal contributors to the condition remain incompletely described and only a single FDA-approved treatment is available. Some studies suggest that the hormones ghrelin and LEAP2, which act as agonist and antagonist/inverse agonist, respectively, for the G protein coupled receptor GHSR, may influence the development of MAFLD. For instance, ghrelin increases hepatic fat whereas synthetic GHSR antagonists do the opposite.

Reducing ghrelin by ghrelin gene knockout (GKO), ghrelin-cell ablation, or high-fat diet feeding increases islet size and β-cell mass in male mice. Here we determined if reducing ghrelin also enlarges islets in females and if pregnancy-associated changes in islet size are related to reduced ghrelin. Islet size and β-cell mass were larger (P = .
