Article Synopsis
- Regular physical activity is essential for overall health, but understanding how endurance exercise affects molecular signaling is still a work in progress.
- The MoTrPAC project aims to explore these molecular responses by conducting structured endurance training on Fischer 344 rats of different ages and sexes, analyzing various tissues and other biological samples.
- The study found significant improvements in muscle function and fitness markers within just a few weeks of exercise, highlighting age- and sex-related differences and providing valuable resources for future research on exercise responses.
This study was designed to evaluate prey selection (type and size) by the octocoral Carijoa riisei at Porto de Galinhas beach, Northeast Brazil, relating prey availability in plankton with the content inside polyps. Diatoms and cyanophytes were the predominant items found in both polyp gastric cavity and plankton. A correlation between prey abundance in the plankton and in the gastric cavity of C.

Further, we have shown that nitric oxide interacts with the metabolic sensor enzyme, AMPK. Therefore, we tested the hypothesis that nitric oxide and AMPK act synergistically to upregulate PGC-1α mRNA expression and stimulate mitochondrial biogenesis in culture.
