In cell-based and animal studies, GHRH-receptor agonism (tesamorelin) and GHS-R1a agonism (ipamorelin) have been reported to engage different intracellular signaling cascades that both terminate in growth-hormone secretion, an arrangement investigators have explored for potentially amplified, rather than simply additive, secretory responses
In 2023, Lopez-Otin proposed twelve markers of aging, including genomic instability, telomere loss, epigenetic changes, loss of protein balance, failure of macroautophagy, dysregulated nutrient sensing, mitochondrial dysfunction, cell senescence, stem cell depletion, altered intercellular communication, chronic inflammation, and dysbiosis
