DSIP has been examined in sleep studies, neuroendocrine experiments and laboratory stress models, but the findings are far from uniform. This review looks at what researchers actually measured, where the results differ and what the current experimental evidence can reasonably establish.
This blog explores how peptides bind and coordinate copper ions, examining the roles of amino-acid sequence, experimental conditions, coordination chemistry, and analytical techniques in copper–peptide research.
Glutathione plays a central role in cellular redox biology, and the present article looks at the methods used for studying reduced and oxidized glutathione in laboratory models, focusing in particular on the GSH/GSSG balance, NADPH-dependent reactions, and research into oxidative stress.
Cell-based studies have examined KPV in relation to NF-κB, MAPK signaling, nuclear transport, and selected molecular markers. This review looks at the experimental endpoints researchers have measured and the limitations of the available evidence.
IGF-1 LR3 has been employed in experimental research involving myogenic cells to study IGF receptor activity and the regulatory function of IGF-binding proteins. In this article, we look at the measurements made in studies using pig cells and consider what conclusions can and cannot be drawn from them.
Peptide Works explores how follistatin is classified as a glycoprotein rather than a steroid and examines its role in TGF-β superfamily research, including its molecular interactions with activin and myostatin.
Examining MGF in mechanobiology research, focusing on how mechanical loading relates to IGF1 gene expression while highlighting the important distinction between MGF-associated transcripts, IGF-1 splice variants, and synthetic MGF-derived peptides
This blog examines experimental evidence showing that GHRP-2 primarily affects growth hormone signalling while also producing smaller measurable prolactin, ACTH, and cortisol responses that help researchers assess its broader endocrine selectivity.
How advances in sensitive TSH assay technology shifted protirelin (TRH) from routine stimulation testing toward specialised research into TRH receptor biology, GPCR signalling and HPT-axis regulation.
Exploring how ACTH and cortisol are used as secondary endocrine markers in GHRP-2 research to characterise its broader neuroendocrine response and evaluate signalling selectivity beyond its primary GHS-R1a interaction.
