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 ...

Acromegaly: pathogenesis & treatment [PDF]

, 2019
Acromegaly is a multi-system disorder whose etiology is most often traced back to a growth hormone-secreting pituitary adenoma (PA). Growth hormone (GH) secretion promotes insulin-like growth factor 1 (IGF-1) release from peripheral tissues, leading to ...

Expression and function of ATP-dependent potassium channels in zebrafish islet β-cells [PDF]

, 2017
ATP-sensitive potassium channels (K(ATP) channels) are critical nutrient sensors in many mammalian tissues. In the pancreas, K(ATP) channels are essential for coupling glucose metabolism to insulin secretion.

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.

ATP mediates both activation and inhibition of K(ATP) channel activity via cAMP-dependent protein kinase in insulin-secreting cell lines. [PDF]

, 1989
The single-channel recording technique was employed to investigate the mechanism conferring ATP sensitivity to a metabolite-sensitive K channel in insulin-secreting cells.

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Expression of interleukin 2 receptors on activated human B cells. [PDF]

, 1984
Using anti-Tac, a monoclonal anti-interleukin 2 (IL-2) receptor antibody, we have explored the possibility that certain activated B cells display receptors for IL-2.

Functional and Structural Evidence of Neurofluid Circuit Aberrations in Huntington Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Disrupted neurofluid regulation may contribute to neurodegeneration in Huntington disease (HD). Because neurofluid pathways influence waste clearance, inflammation, and the distribution of central nervous system (CNS)–delivered therapeutics, understanding their dysfunction is increasingly important as targeted treatments emerge.

ROCKII inhibition promotes the maturation of human pancreatic beta-like cells

Nature Communications, 2017
Our incomplete understanding of how pancreatic beta cells form limits the generation of beta-like cells from human pluripotent stem cells (hPSC). Here, the authors identify a ROCKII inhibitor H1152 as increasing insulin secreting cells from hPSCs and ...

Effect of 2‐mercaptoethanol on glutathione levels, cystine uptake and insulin secretion in insulin‐secreting cells [PDF]

European Journal of Biochemistry, 1992
The role of glutathione (GSH) in the differentiated state of insulin‐secreting cells was studied using 2‐mercaptoethanol as a means of varying intracellular GSH levels. 2‐Mercaptoethanol (50 μM) caused a marked increase of GSH in two rat insulinoma cell lines, RINm5F and INS‐1, the latter being dependent on the presence of 2‐mercaptoethanol for ...
