  • 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…

  • Transferrin binding and PH

    Transferrin binding to transferrin receptors reduces its affinity for iron. Two pathways can occur once endocytosed–degradation or recycling pathways. The degradation pathway is where the dissociation of ferric ions from transferrin occurs from an early and late endosome. Iron can now be utilized for storage or incorporated into hemoglobin. The recycling pathway involves the recycling of…

  • DMT1 aka DCT1 and NRAMP2

    Natural resistance-associated macrophage protein 2 (NRAMP 2), also known as divalent metal transporter 1 (DMT1) and divalent cation transporter 1 (DCT1), is a protein that in humans is encoded by the SLC11A2 (solute carrier family 11, member 2) gene. DMT1 represents a large family of orthologous metal ion transporter proteins that are highly conserved from bacteria to humans. As its name suggests, DMT1 binds a variety of divalent metals…
