Published online at http://diabetes.diabetesjournals.org/lookup/suppl/doi:10.2337/db18-1066/-/DC1 SUPPLEMENTARY DATA Western immunoblotting Skeletal muscle samples were lysed up in 1D‐sample buffer (10% glycerol, 62.5 mmol/L Tris (pH 6.8), 2% w/v LDS, 2% w/v DTT) and protein concentration was determined using Pierce 660‐nm protein assay (Thermo scientific, Waltham, MA USA 02 451; 22 660) according to the manufacturer's instructions. Heat shock protein 90 immunoblotting was performed by application of samples (5 µg protein) on 4‐15% Criterion TGX gels (Biorad, Veenendaal, the Netherlands, 5 671 084) and semi‐dry blotting onto PVDF membranes (GE Healthcare‐Fisher, RPN1416F), incubated overnight with rat monoclonal HSP90 antibody (1:1000 dilution) after blocking with 5% milk in TBS‐T (137 mM NaCl, 20 mmol/L Tris pH 7.0 and 0.1% (v/v) Tween [Sigma‐Aldrich, P7949]). After 2 hours incubation with anti-rat, horse radish peroxidase-coupled secondary antibody (Thermo Fisher 62-9520), the blot was stained using ECL‐prime (Fisher scientific, 10 308 449) and analysed on an AI‐600 imaging system (GE Healthcare, Life Sciences). Four samples from each group were loaded on gel. Supplementary Table 1. Body weight and glucose infusion rate (GIR) in all groups.

Since severely ill patients often show elevated methemoglobin (MetHb) and carboxyhemoglobin (COHb) concentrations in their blood as a marker of disease severity, we aimed to summarize the currently available published study results (case reports and cross-sectional studies) on MetHb and COHb concentrations in the blood of COVID-19 patients. To this end, a systematic literature research was performed. For the case of MetHb, seven publications were identified (five case reports and two cross-sectional studies), and for the case of COHb, three studies were found (two cross-sectional studies and one case report). The findings reported in the publications show that an increase in MetHb and COHb can happen in COVID-19 patients, especially in critically ill ones, and that MetHb and COHb can increase to dangerously high levels during the course of the disease in some patients.

  • Concentration of NADH-Cytochrome B5 Reductase in Erythrocytes of Normal and Methemoglobinemic Individuals Measured with a Quantitative Radioimmunoblotting Assay
    Concentration of NADH-cytochrome b5 reductase in erythrocytes of normal and methemoglobinemic individuals measured with a quantitative radioimmunoblotting assay. N Borgese, … , G Pietrini, S Gaetani J Clin Invest. 1987;80(5):1296-1302. https://doi.org/10.1172/JCI113205. Research Article The activity of NADH-cytochrome b5 reductase (NADH-methemoglobin reductase) is generally reduced in red cells of patients with recessive hereditary methemoglobinemia. To determine whether this lower activity is due to reduced concentration of an enzyme with normal catalytic properties or to reduced activity of an enzyme present at normal concentration, we measured erythrocyte reductase concentrations with a quantitative radioimmunoblotting method, using affinity-purified polyclonal antibodies against rat liver microsomal reductase as probe. In five patients with the "mild" form of recessive hereditary methemoglobinemia, in which the activity of erythrocyte reductase was 4-13% of controls, concentrations of the enzyme, measured as antigen, were also reduced to 7-20% of the control values. The concentration of membrane-bound reductase antigen, measured in the ghost fraction, was similarly reduced. Thus, in these patients, the reductase deficit is caused mainly by a reduction in NADH-cytochrome b5 reductase concentration, although altered catalytic properties of the enzyme may also contribute to the reduced enzyme activity.

  • Comparative Study of the Primary Structures of Cytochrome B5 from Four Species* Akira Tsugitat, Midori Kobayashi, Seiji Tani, Sukei Kyo, M
    Proceedings ofthe National Academy ofSciences Vol. 67, No. 1, pp. 442-447, September 1970 Comparative Study of the Primary Structures of Cytochrome b5 from Four Species* Akira Tsugitat, Midori Kobayashi, Seiji Tani, Sukei Kyo, M. A. Rashidt, Yukuo Yoshida, Toshimasa Kajihara, and Bunji Hagihara LABORATORY OF MOLECULAR GENETICS AND DEPARTMENT OF BIOCHEMISTRY, OSAKA UNIVERSITY MEDICAL SCHOOL, OSAKA, JAPAN Communicated by Britton Chance, April 1, 1970 Abstract. The primary structures of human, bovine, and chicken cytochrome bN have been determined and compared with that of the previously studied rabbit protein. One peptide containing 31 amino acid residues and another con- taining 10 were found common to all four species. The substitutions of amino acids between species could be accounted for mainly by single base exchange, with a few exceptional double base exchanges for the chicken. Results for bovine cytochrome b5 differ significantly from those previously reported for calf cyto- chrome N5. Cytochrome b5 is a hemoprotein with a role in the microsomal electron- transport system. The prosthetic group of the protein is a protoheme identical with that of hemoglobin and myoglobin.' The main interest of the work to be described resides in the relationship between the function and structure of cytochrome b5, hemoglobin, and myoglobin. Primary and tertiary structures of hemoglobin and myoglobin, together with details of their functional roles, have been reported.2-5 In contrast, little is known about cytochrome b5 except for the primary structures of two cytochromes b5.6-8 This communication describes and compares the primary structures of human, bovine, rabbit, and chicken hepatic cytochrome b5.

  • Myoglobin-Mediated Oxygen Delivery to Mitochondria of Isolated Cardiac Myocytes (Electron Transport/Heart Cells/Cytochrome Oxidase) BEATRICE A
    Proc. Nati. Acad. Sci. USA Vol. 84, pp. 7503-7507, November 1987 Biochemistry Myoglobin-mediated oxygen delivery to mitochondria of isolated cardiac myocytes (electron transport/heart cells/cytochrome oxidase) BEATRICE A. WITTENBERG* AND JONATHAN B. WITTENBERG Department of Physiology and Biophysics, Albert Einstein College of Medicine, Bronx, NY 10461 Communicated by Berta Scharrer, July 20, 1987 (receivedfor review May 5, 1987) ABSTRACT Myoglobin-mediated oxygen delivery to in- Cytochrome oxidase, half-oxidized when ambient oxygen tracellular mitochondria is demonstrated in cardiac myocytes partial pressure (Po2) is 0.07 torr (1 torr = 133 Pa) (16), in the isolated from the hearts of mature rats. Myocytes are held at circumstance described here experiences oxygen pressures high ambient oxygen pressure, 40-340 torr (5-45 kPa); 20- to 200-fold the pressure required to maintain the normal, sarcoplasmic myoglobin is fully oxygenated. In this condition largely oxidized, state seen in resting myocytes (16). Carbon oxygen availability does not limit respiratory rate; myoglobin- monoxide in this circumstance blocks oxygenation of facilitated diffusion contributes no additional oxygen flux and, sarcoplasmic myoglobin selectively without perturbing the since oxygen consumption is measured in steady states, the optical spectrum of intracellular cytochrome oxidase. We storage function of myoglobin vanishes. Carbon monoxide, conclude that cardiac mitochondria accept two additive introduced stepwise, displaces oxygen from intracellular simultaneous flows of oxygen: the well-known flow of dis- oxymyoglobin without altering the optical spectrum of the solved oxygen to cytochrome oxidase and a flow of largely oxidized intracellular mitochondria. A large part, myoglobin-bound oxygen to a mitochondrial terminus. The about one-third, of the steady-state oxygen uptake is abolished myoglobin-mediated oxygen flow supports ATP generation by carbon monoxide blockade of myoglobin oxygenation.
