Glucose metabolism and oscillatory behavior of pancreatic islets [PDF]

, 2005
A variety of oscillations are observed in pancreatic islets.We establish a model, incorporating two oscillatory systems of different time scales: One is the well-known bursting model in pancreatic beta-cells and the other is the glucose-insulin feedback ...

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

FEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

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.

Insulin Secretion in Malignant Hyperpyrexia [PDF]

BMJ, 1974
An increased glucose-induced insulin response has been observed in patients susceptible to malignant hyperpyrexia. This raises the possibility that the membrane abnormality present in the calcium-storing membranes in the muscle cell in malignant hyperpyrexia may be present also in the beta cell of the pancreas.

A subcutaneous adipose tissue-liver signalling axis controls hepatic gluconeogenesis. [PDF]

, 2015
The search for effective treatments for obesity and its comorbidities is of prime importance. We previously identified IKK-ε and TBK1 as promising therapeutic targets for the treatment of obesity and associated insulin resistance. Here we show that acute

The role of lipid metabolism in neuronal senescence

FEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells

FEBS Open Bio, EarlyView.
Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

Involvement of the Adhesion GPCRs Latrophilins in the Regulation of Insulin Release

Cell Reports, 2019
Summary: Insulin secretion from pancreatic β cells is a highly complex and tightly regulated process. Its dysregulation is one characteristic of type 2 diabetes, and thus, an in-depth understanding of the mechanisms controlling insulin secretion is ...

TRPC3 Regulates Islet Beta‐Cell Insulin Secretion

Advanced Science, 2023
Insulin release is tightly controlled by glucose‐stimulated calcium (GSCa) through hitherto equivocal pathways. This study investigates TRPC3, a non‐selective cation channel, as a critical regulator of insulin secretion and glucose control.

Insulin clearance and the incidence of type 2 diabetes in Hispanics and African Americans: the IRAS Family Study. [PDF]

, 2013
ObjectiveWe aimed to identify factors that are independently associated with the metabolic clearance rate of insulin (MCRI) and to examine the association of MCRI with incident type 2 diabetes in nondiabetic Hispanics and African Americans.Research ...
