Controlling cancer cells’ gluttony for glutamine

Researchers at Sanford Burnham Prebys found that pancreatic cancer cells rely on a specific nutrient, glutamine, to fuel their unchecked growth. The study identified two enzymes, aPKC zeta and iota, that play a regulatory role in the process of macropinocytosis, allowing cancer cells to scavenge alternative resources.

Study shows how high blood sugar increases risk of thrombosis

Researchers from Brazil's Center for Research on Redox Processes in Biomedicine found that high blood sugar can cause thrombosis by altering endothelial function and promoting platelet adhesion. They identified a specific molecular mechanism involving protein disulfide isomerase A1 as a key regulator of this process.

Potential new target for early treatment of Alzheimer's disease

A study found that targeting heparan sulfate-modified proteins improves cell repair, rescues neuron loss and reverses cellular changes associated with neurodegenerative diseases. Disrupting these proteins promotes autophagy-dependent cell repair and reverses early cellular problems in models of Alzheimer's.

A clutch stretch goes a long way

Researchers at Kyoto University have observed a unique phenomenon where talin constantly moves over focal adhesions as a single unit, contradicting prevailing notions. This discovery reveals that talin manages to simultaneously maintain the intercellular connection while transmitting force through dynamic molecular stretching.
