Researchers at Brown University have found a way to extend the lifespan of flies by suppressing a hormone that regulates insulin secretion. The study suggests that certain medications used to treat human obesity and diabetes may also impact aging, making it a promising area of research for future studies.

Researchers determined the cryo-EM structure of IGF Ternary complex and its assembly & activation mechanism. The study reveals how IGFBP3 and ALS form a stable complex with IGF1, regulating its activity. The findings provide new insights into growth-related diseases such as growth hormone deficiency and ALS deficiency.

A multi-pillar approach to nutrition can help increase lifespan by promoting optimal carbohydrate intake from non-refined sources, low but sufficient protein from plant-based sources, and enough plant-based fats. The 'longevity diet' may also involve intermittent fasting and a 5-day cycle of a fasting or fasting-mimicking diet every 3-...

A genome-wide screen of zebrafish identified an enzyme, pregnancy-associated plasma protein-aa (pappaa), that promotes learning and memory by increasing IGF availability to neurons. The study's findings have implications for understanding human neuropsychiatric disorders, such as schizophrenia, autism, and obsessive-compulsive disorder.

A research team has discovered the first functional insulin-like growth factor binding protein (IGFBP) ortholog in invertebrates. The newly identified protein, called imaginal morphogenesis protein-late 2 (Imp-L2), binds to insulin and inhibits its growth-promoting function, regulating growth control and insulin signaling.
