A TRPM4 Inhibitor 9-Phenanthrol Inhibits Glucose- and Glucagon-Like Peptide 1-Induced Insulin Secretion from Rat Islets of Langerhans

Journal of Diabetes Research, 2017
Pancreatic β-cells express several ion channels of the transient receptor potential family, which play important roles in mediating the stimulus-secretion coupling. One of these channels, the TRPM4 is a Ca2+-activated monovalent cation channel.

Insulin signaling pathways in lepidopteran steroidogenesis

Frontiers in Physiology, 2014
Molting and metamorphosis are stimulated by the secretion of ecdysteroid hormones from the prothoracic glands. Insulin-like hormones have been found to enhance prothoracic gland activity, providing a mechanism to link molting to nutritional state.

Modulation of large dense core vesicle insulin content mediates rhythmic hormone release from pancreatic beta cells over the 24h cycle. [PDF]

PLoS ONE, 2018
The rhythmic nature of insulin secretion over the 24h cycle in pancreatic islets has been mostly investigated using transcriptomics studies showing that modulation of insulin secretion over this cycle is achieved via distal stages of insulin secretion ...

Oestrogens and insulin secretion [PDF]

Diabetologia, 2005
There is a persistent perception that oestrogens have an adverse effect on carbohydrate metabolism. It might therefore be expected that their use would result in a corresponding increase in the incidence of diabetes. Recent evidence from clinical trials suggesting that women on postmenopausal oestrogen hormone replacement therapy (HRT) have a reduced ...

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

The contrasting effects of two antimalarial drugs on insulin secretion

Cellular and Molecular Life Sciences
Quinolines and artemisinins are the two most important antimalarial drugs worldwide. In addition to antimalarial effects, quinine has been extensively documented to directly stimulate insulin secretion, potentially causing hypoglycemia in malaria ...

ARHGAP21 Acts as an Inhibitor of the Glucose-Stimulated Insulin Secretion Process

Frontiers in Endocrinology, 2020
ARHGAP21 is a RhoGAP protein implicated in the modulation of insulin secretion and energy metabolism. ARHGAP21 transient-inhibition increase glucose-stimulated insulin secretion (GSIS) in neonatal islets; however, ARHGAP21 heterozygote mice have a ...

Effects of GCK, GCKR, G6PC2 and MTNR1B variants on glucose metabolism and insulin secretion. [PDF]

PLoS ONE, 2010
BACKGROUND:Single nucleotide polymorphisms (SNPs) from GCK, GCKR, G6PC2 and MTNR1B were found to modulate the fasting glucose levels. The current study aimed to replicate this association in the Chinese population and further analyze their effects on ...

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Myricetin Amplifies Glucose–Stimulated Insulin Secretion via the cAMP-PKA-Epac-2 Signaling Cascade

Biomedicines
Aim: Myricetin, a natural bioflavonoid, is reported as an anti-diabetic agent since it possesses the ability to inhibit α-glucosidase activity, stimulate insulin action and secretion, manage ROS, and prevent diabetes complications.
