Cardiac aging is an intrinsic process that leads to impaired heart function, along with cellular and molecular changes. Recent research highlights the important role of mitochondria in cardiac function, due to the heart's high energy demands. Serum response factor (SRF), a transcription factor involved in regulating actin and smooth muscle gene expression, is well known as a regulator of various aspects of cardiac function. Ho...

In a recent randomized, double-blind, placebo-controlled trial, we were able to demonstrate the superiority of a dietary supplement composed of essential amino acids (EAAs) over whey protein, in older adults with low physical function. In this paper, we describe the comparative plasma protein expression in the same subject groups of EAAs vs whey. The plasma proteomics data was generated using SOMA scan assay. A total of twenty...
