“Dr. Shinya Yamanaka discovered a group of proteins that can reprogram differentiated (mature) cells into pluripotent stem cells. These proteins, now called Yamanaka factors, are highly expressed in embryonic stem cells in mice and humans.”

“The effects of heat stress on longevity have also been shown in lower organisms including flies and worms, increasing their lifespans by as much as 15 percent. The mechanism of lifespan extension was also teased out in these organisms and shown to be specifically dependent on heat shock proteins.”

“Collagen is a lower-quality protein for skeletal muscle because it provides relatively little leucine and lacks a balanced essential-amino-acid profile. Dr. van Loon therefore would not use it in place of a complete protein when the goal is muscle protein synthesis.”

“While daily fluctuations in testosterone do not drive muscle protein synthesis, supraphysiological steroid doses are anabolic. Testosterone boosters come and go, but Dr. Phillips states they are ineffective, and it's better to focus on resistance exercise.”

“Using a mouse model of Alzheimer's disease, researchers gave one group of mice free access to food throughout the day but fed another group on a time-restricted schedule (limited to a six-hour window each day), translating to about 14 hours of fasting for humans.”

“Dr. Patrick explores heat shock proteins as one possible mechanism. Heat stress activates proteins that help maintain protein structure and clear damaged proteins, and animal models suggest that this system can limit amyloid aggregation.”

“I also share my thoughts on flavored sparkling waters, non-nutritive sweeteners, and protein powders—and when "natural" might not be the better choice.”

“Sirtuins utilize NAD+ to remove specific chemical structures called acetyl groups – a process called deacetylation – from cellular proteins to control transcriptional regulation, energy metabolism, circadian rhythms, DNA repair, and cell survival.”
