  • HFE H63D & VO2 max

    SMOKE EM IF YOU GOT EM The HFE H63D is a single-nucleotide polymorphism in the HFE gene (c.187C>G, rs1799945), which results in the substitution of a histidine for an aspartic acid at amino acid position 63 of the HFE protein (p.His63Asp). HFE participates in the regulation of iron absorption. Homozygous H63D variant can occasionally be the cause of hemochromatosis. It is also…

  • Osteopontin (OPN)

    Osteopontin (OPN), also known as bone /sialoprotein I (BSP-1 or BNSP), early T-lymphocyte activation (ETA-1), secreted phosphoprotein 1 (SPP1), 2ar and Rickettsia resistance (Ric), is a protein that in humans is encoded by the SPP1 gene (secreted phosphoprotein 1). The murine ortholog is Spp1. Osteopontin is a SIBLING (glycoprotein) that was first identified in 1986 in osteoblasts. The family of non-collagenous proteins known as SIBLING proteins, standing for small integrin-binding ligand, N-linked glycoprotein, are components of the extracellular matrix of bone and dentin. Evidence shows that these proteins play key…

  • Gastric inhibitory peptide aka GIP and receptors

    Gastric inhibitory polypeptide or gastric inhibitory peptide also known as glucose-dependent insulinotropic polypeptide abbreviated as GIP, is an inhibiting hormone of the secretin family of hormones. While it is a weak inhibitor of gastric acid secretion, its main role is to stimulate insulin secretion. GIP, along with glucagon-like peptide-1 (GLP-1), belongs to a class of molecules referred to as incretins. Synthesis and transport GIP is derived from a 153-amino acid proprotein encoded by…

  • Somatostatin

    Not to be confused with Somatocrinin or Somatomedin. Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or by several other names, is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin inhibits insulin and glucagon secretion.  “somatostatin”. Encyclopædia Britannica. Encyclopædia Britannica Online. Encyclopædia Britannica Inc., 2016. Web. 04 mag. 2016…

  • Corticotropin-like intermediate [lobe] peptide (CLIP)

    Corticotropin-like intermediate [lobe] peptide (CLIP), also known as adrenocorticotropic hormone fragment 18-39 (ACTH(18-39)), is a naturally occurring, endogenous neuropeptide with a docosapeptide structure and the amino acid sequence  Arg-Pro-Val-Lys-Val-Tyr-Pro-Asn-Gly-Ala-Glu-Asp-Glu-Ser-Ala-Glu-Ala-Phe-Pro-Leu-Glu-Phe. CLIP is generated as a proteolyic cleavage product of adrenocorticotropic hormone (ACTH), Gianoulakis C, Seidah NG, Routhier R, Chrétien M (December 1979). “Biosynthesis and characterization of adrenocorticotropic hormone, alpha-melanocyte-stimulating hormone, and an NH2-terminal fragment of the adrenocorticotropic hormone/beta-lipotropin precursor from rat pars intermedia”. The…

  • Progastrin

    Progastrin is an 80-amino acid intracellular protein and the precursor of gastrin, a gastrointestinal hormone produced by G cells in the gastric antrum. Fiona M., Gribble; Frank, Reimann; Geoffrey, P. Roberts (2018). Gastrointestinal Hormones. Physiology of the Gastrointestinal Tract, Elsevier. pp. 31–70.  The main function of gastrin is to regulate acid secretion. Rehfeld, Jens F.; Goetze, Jens Peter (2005). “2 The Post-Translational Phase of Gene Expression in Tumor…
