1. Dexamethasone and Nutraceutical Therapy Can Reduce the Myalgia Due to COVID-19 - a Systemic Review of the Active Substances that Can Reduce the Expression of Interlukin-6
Umberto Ripani, Michele Bisaccia, Luigi Meccariello Med Arch. 2022 Feb;76(1):66-71. doi: 10.5455/medarh.2022.76.66-71.
Background: Myalgia reflects generalized inflammation and cytokine response and can be the onset symptom of 36% of patients with COVID-19. Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF- α) levels in plasma and upper respiratory secretions directly correlate with the magnitude of viral replication, fever, and respiratory and systemic symptoms, including musculoskeletal clinical manifestations. Objective: The aim of our work is to report literature scientific investigation clinical protocol to reduce the immunomodulation and inflammatory response nutraceutical therapy associated with dexamethasone and how can reduce the expression of Interlukina-6(IL-6) and myalgia due to COVID-19. Methods: We searched in Pubmed and Cochrane the nautriceutical drugs to treat the immune modulation of organism to COVID-19. We put these keywords: immune inflammation, desease descriptions, epidemiology COVID-19; immunomodulations; IL-6; Rheumatic Symptoms; Joint; Musculoskeletal Disorders; dexamethasone; Polydatin; Zinc; Melatonin; N- Acetyl Cysteine; Colostrum; L- Glutamine; Vitamin D3. Results: We found 61 papers. All the authors analyze them. After the Analyze we suggest the use of response nutraceutical therapy associated with dexamethasone can reduce the expression of Interlukina-6(IL-6) and myalgia due to COVID-19. Conclusion: According the scientific literature nutraceutical therapy associated with dexamethasone can reduce the expression of Interlukina-6(IL-6) and myalgia due to COVID-19.
2. UCP1-dependent and UCP1-independent metabolic changes induced by acute cold exposure in brown adipose tissue of mice
Yuko Okamatsu-Ogura, Masashi Kuroda, Rie Tsutsumi, Ayumi Tsubota, Masayuki Saito, Kazuhiro Kimura, Hiroshi Sakaue Metabolism. 2020 Dec;113:154396. doi: 10.1016/j.metabol.2020.154396. Epub 2020 Oct 14.
Background: Brown adipose tissue (BAT) is a site of metabolic thermogenesis mediated by mitochondrial uncoupling protein 1 (UCP1) and represents a target for a therapeutic intervention in obesity. Cold exposure activates UCP1-mediated thermogenesis in BAT and causes drastic changes in glucose, lipid, and amino acid metabolism; however, the relationship between these metabolic changes and UCP1-mediated thermogenesis is not fully understood. Methods: We conducted metabolomic and GeneChip array analyses of BAT after 4-h exposure to cold temperature (10 °C) in wild-type (WT) and UCP1-KO mice. Results: Cold exposure largely increased metabolites of the glycolysis pathway and lactic acid levels in WT, but not in UCP1-KO, mice, indicating that aerobic glycolysis is enhanced as a consequence of UCP1-mediated thermogenesis. GeneChip array analysis of BAT revealed that there were 2865 genes upregulated by cold exposure in WT mice, and 838 of these were upregulated and 74 were downregulated in UCP1-KO mice. Pathway analysis revealed the enrichment of genes involved in fatty acid (FA) β oxidation and triglyceride (TG) synthesis in both WT and UCP1-KO mice, suggesting that these metabolic pathways were enhanced by cold exposure independently of UCP1-mediated thermogenesis. FA and cholesterol biosynthesis pathways were enhanced only in UCP1-KO mice. Cold exposure also significantly increased the BAT content of proline, tryptophan, and phenylalanine amino acids in both WT and UCP1-KO mice. In WT mice, cold exposure significantly increased glutamine content and enhanced the expression of genes related to glutamine metabolism. Surprisingly, aspartate was almost completely depleted after cold exposure in UCP1-KO mice. Gene expression analysis suggested that aspartate was actively utilized after cold exposure both in WT and UCP1-KO mice, but it was replenished from intracellular N-acetyl-aspartate in WT mice. Conclusions: These results revealed that cold exposure induces UCP1-mediated thermogenesis-dependent glucose utilization and UCP1-independent active lipid metabolism in BAT. In addition, cold exposure largely affects amino acid metabolism in BAT, especially UCP1-dependently enhances glutamine utilization. These results contribute a comprehensive understanding of UCP1-mediated thermogenesis-dependent and thermogenesis-independent metabolism in BAT.
3. Crystal structure of N-terminal degron-truncated human glutamine synthetase
Min Fey Chek, Sun Yong Kim, Tomoyuki Mori, Hisayuki Kojima, Toshio Hakoshima Acta Crystallogr F Struct Biol Commun. 2021 Nov 1;77(Pt 11):427-434. doi: 10.1107/S2053230X21010748. Epub 2021 Oct 29.
Glutamine synthetase (GS) is a decameric enzyme that plays a key role in nitrogen metabolism. Acetylation of the N-terminal degron (N-degron) of GS is essential for ubiquitylation and subsequent GS degradation. The full-length GS structure showed that the N-degron is buried inside the GS decamer and is inaccessible to the acetyltransferase. The structure of N-degron-truncated GS reported here reveals that the N-degron is not essential for GS decamer formation. It is also shown that the N-degron can be exposed to a solvent region through a series of conformational adjustments upon ligand binding. In summary, this study elucidated the dynamic movement of the N-degron and the possible effect of glutamine in enhancing the acetylation process.
