Bioenergetic analysis of pancreatic beta-cells shows impaired metabolic signature in type 2 diabetes patients

Bioenergetic analysis of pancreatic beta-cells shows impaired metabolic signature in type 2 diabetes patients

Impaired activation of mitochondrial energy metabolism in the presence of glucose has been demonstrated in pancreatic beta-cells from patients with type 2 diabetes. The cause of this dysfunction has been unknown. Publishing online in Endocrinology, Buck Institute assistant research professor Akos Gerencser, PhD, shows that in patients with type 2 diabetes the balance between supply and demand of the mitochondrial membrane potential (ΔψM) is altered causing a decrease in the signaling that turns on insulin secretion.

New approach to imaging glucose uptake activity in single living cells

New approach to imaging glucose uptake activity in single living cells

Researchers at Columbia University have reported a new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance. In a recent study published in Angewandte Chemie International Edition, Associate Professor of Chemistry Wei Min's team developed a new glucose analogue that can mimic the natural glucose, and imaged its uptake as energy source by living cancer cells, neurons and tissues at the single cell level.

Chromosomes play active role in animal cell division

Chromosomes play active role in animal cell division

Canadian and British researchers have discovered that chromosomes play an active role in animal cell division. This occurs at a precise stage - cytokinesis - when the cell splits into two new daughter cells. [More]
Scientists uncover new genes that affect development and maintenance of blood stem cell

Scientists uncover new genes that affect development and maintenance of blood stem cell

Even though the transplantation of blood stem cells, also known as bone marrow, has saved many lives over many decades, the genes that control the number or function of blood stem cells are not fully understood. In a study published in June in Stem Cell Reports, the USC Stem Cell labs of Hooman Allayee and Gregor Adams uncovered new genes that affect blood stem cell development and maintenance. [More]
