Growth hormone receptor in VGLUT2 or Sim1 cells regulates glycemia and insulin sensitivity.

Growth hormone (GH) has several metabolic effects, including a profound impact on glucose homeostasis. For example, GH oversecretion induces insulin resistance and increases the risk of developing diabetes mellitus. Here, we show that GH receptor (GHR) ablation in vesicular glutamate transporter 2 (VGLUT2)-expressing cells, which comprise a subgroup of glutamatergic neurons, led to a slight decrease in lean body mass without inducing changes in body adiposity.

Does controlled, gradually increased venous pressure exposure (dangling) of the lower extremity after free flap reconstructions reduce partial flap loss? A multicenter randomized controlled trial.

Introduction: Controlled, gradually increased venous pressure exposure of lower extremity free flaps (dangling) is common, based on the assumption that this reduces (partial) flap loss. Dangling protocols potentially increase length of hospital stay and resource utilization. We investigated whether: (1) the proportion of partial flap loss 6 weeks after lower extremity free flap reconstruction is non-inferior after uncontrolled exposure compared to gradually increased venous pressure exposure; (2) there is a difference in length of hospital stay and major or minor adverse events 3 months after surgery.

Characterization and Regulation of the Neonatal Growth Hormone Surge.

High neonatal growth hormone (GH) secretion has been described in several species. However, the neuroendocrine mechanisms behind this surge remain unknown. Thus, the pattern of postnatal GH secretion was investigated in mice and rats.

Growth Hormone Receptor in Lateral Hypothalamic Neurons Is Required for Increased Food-Seeking Behavior during Food Restriction in Male Mice.

Growth hormone (GH) action in the brain regulates neuroendocrine axes, energy and glucose homeostasis, and several neurological functions. The lateral hypothalamic area (LHA) contains numerous neurons that respond to a systemic GH injection by expressing the phosphorylated STAT5, a GH receptor (GHR) signaling marker. However, the potential role of GHR signaling in the LHA is unknown.
