MCT1 is expressed in most tissues and is especially prominent in the heart, red skeletal muscle, erythrocytes, and all cells under hypoxic conditions, where it can either be involved in the uptake or efflux of glycolytically produced lactic acid
Different mechanisms, different side-effect profiles
Cyanocobalamin is indicated for Vitamin B12 deficiencies due to malabsorption which may be associated with the following conditions: Addisonian (pernicious) anemia Gastrointestinal pathology, dysfunction, or surgery, including gluten enteropathy or sprue, small bowel bacterial overgrowth, total or partial gastrectomy Fish tapeworm infestation Malignancy of pancreas or bowel Folic acid deficiency It may be possible to treat the underlying disease by surgical correction of anatomic lesions leading to small bowel bacterial overgrowth, expulsion of fish tapeworm, discontinuation of drugs leading to vitamin malabsorption (see Drug/Laboratory Test Interactions), use of a gluten-free diet in nontropical sprue, or administration of antibiotics in tropical sprue
According to the available research, topical peptides such as GHK-Cu, acetyl hexapeptide-3/8, palmitoyl tripeptide-5, and others do not appear to exert any side effects when applied topically
50.7% of those in the methotrexate arm, which was statistically different
The Gly-His-Lys tripeptide chelates a single copper-2 ion at a square-planar coordination pocket built from the histidine imidazole nitrogen and adjacent backbone amides
