Mitochondrial biology has expanded significantly over the past two decades. Rather than acting solely as cellular energy producers, mitochondria function as dynamic signalling organelles communicating physiological data to the nucleus. This mitochondrial retrograde signalling maintains cellular home…

Cellular biology increasingly recognises mitochondria not merely as metabolic engines, but as active signalling hubs communicating stress status directly to the nucleus. This retrograde signalling pathway relies on mitochondrial-derived peptides (MDPs) encoded within the organelle's own genome. Amo…

Controlling endothelial nitric oxide synthase (eNOS) regulation remains a strict parameter in in-vitro vascular biology protocols. As the primary enzymatic source of nitric oxide (NO), eNOS operates as a core signalling molecule that modulates intercellular adhesion and barrier function. Preserving…

The synthetic tetrapeptide Epithalon (L-alanyl-L-glutamyl-L-aspartyl-glycine) serves as an in-vitro model for investigating short-chain peptide interactions with chromatin architecture. Designed as an analogue of epithalamin—a naturally occurring pineal gland fraction—the compound allows researchers…

The study of melanocortin receptor agonists has expanded significantly over the past several decades, transitioning from general investigations into skin pigmentation to specific analyses of isolated central nervous system (CNS) pathways. At the forefront of this research is PT-141, a synthetic cyc…
