One Week Exposure to a Somatostatin Receptor 2 Antagonist (SSTR2a) Enhances Glucagon Counterregulation to Insulin‐Induced Hypoglycaemia and Does Not Worsen Glycemia in a Male Rat Model of Insulin‐Requiring Type 2 Diabetes

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 9, Page 8208-8218, September 2026.
ABSTRACT Introduction Administration of a somatostatin receptor 2 antagonist (SSTR2a) increases glucagon responsiveness to hypoglycaemia in insulin‐treated type 2 diabetes (T2D), but the durability of this effect and the impact of repeated SSTR2a dosing on overall glycaemia in T2D are unclear.

Intra‐Islet Paracrine Regulation of Glucagon Secretion During Hypoglycemia, Euglycemia, and Hyperglycemia

open access: yesAnnals of the New York Academy of Sciences, Volume 1563, Issue 1, September 2026.
Glucagon, a counterregulatory hormone released from pancreatic α‐cells, maintains glucose homeostasis by acting as a protective barrier against hypoglycemia and an amplifier of insulin release when glucose levels rise with feeding. In the body, glucagon secretion is regulated by circulating glucose levels, with elevations in amino acids and via other ...

Ghrelin and eating behavior: evidence and insights from genetically-modified mouse models

open access: yesFrontiers in Neuroscience, 2013
Ghrelin is an octanoylated peptide hormone, produced by endocrine cells of the stomach, which acts in the brain to increase food intake and body weight.

Acute high‐protein feeding induces hepatic amino acid accumulation in diabetic male mice prior to transcriptional adaptation

open access: yesPhysiological Reports, Volume 14, Issue 18, September 2026.
Abstract Glucagon plays a pivotal role in hepatic amino acid metabolism; acute high‐protein diet feeding and diabetic condition both induce enhanced glucagon secretion. However, it remains unknown whether these two conditions alter hepatic amino acid metabolism through the same or different pathways.

Growth Hormone (GH)-Releasing Peptide Stimulation of GH Release from Human Somatotroph Adenoma Cells: Interaction with GH-Releasing Hormone, Thyrotropin- Releasing Hormone, and Octreotide. [PDF]

open access: yes, 1994
The synthetic hexapeptide GH-releasing peptide (GHRP; His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) specifically stimulates GH secretion in humans in vivo and in animals in vitro and in vivo via a still unknown receptor and mechanism.

Expression pattern of the fused in sarcoma gene and its contextual influence on the density-specific response of the growth hormone/insulin-like growth factor 1 axis in zig-zag eels (Mastacembelus armatus)

open access: yesFrontiers in Marine Science
The fused in sarcoma (FUS) protein is a DNA/RNA binding protein from the ten-eleven translocation protein family that is associated with neurodegeneration, and it has been shown to promote cell proliferation through the growth hormone/insulin-like growth

Activation of GHSRs Facilitates the Excitability of Dentate Gyrus Granule Cells and Short‐Term Spatial Memory via Multiple Ionic and Signaling Mechanisms

open access: yesAdvanced Biology, Volume 10, Issue 8, August 2026.
Ghrelin excites the dentate gyrus (DG) granule cells via GHSR‐mediated modulation of diverse ionic channels and activation of D1R, cAMP, and EPAC2. Similarly, overnight calorie restriction alters neuronal excitability in a ghrelin‐dependent manner. Infusion of ghrelin directly into the DG improves short‐term spatial memory in the Y‐maze, providing ...

Anosmin-1 modulates fibroblast growth factor receptor 1 signaling in human gonadotropin-releasing hormone olfactory neuroblasts through a heparan sulfate-dependent mechanism [PDF]

open access: yes, 2004
Defects of either anosmin-1 or fibroblast growth factor receptor 1 (FGFR1) are known to underlie hereditary Kallmann's syndrome (KS), a human disorder of olfactory and gonadotropin-releasing hormone (GnRH) neuronal ontogeny.

Impact of Proestrus on Gene Expression in the Medial Preoptic Area of Mice

open access: yesFrontiers in Cellular Neuroscience, 2017
The antero-ventral periventricular zone (AVPV) and medial preoptic area (MPOA) have been recognized as gonadal hormone receptive regions of the rodent brain that—via wiring to gonadotropin-releasing hormone (GnRH) neurons—contribute to orchestration of ...

Type 2 Diabetes Mellitus: Molecular Pathogenesis and Therapeutic Interventions

open access: yesMedComm, Volume 7, Issue 8, August 2026.
This graphical summary illustrates the multiorgan therapeutic landscape for Type 2 diabetes mellitus (T2D), integrating molecular pathogenesis with modern treatment strategies. It depicts how current interventions, including SGLT2 inhibitors, GLP‐1 receptor agonists, and insulin secretagogues, target key organs—kidney, pancreas, gastrointestinal tract,
