Res Pharm Sci 2021; 16:250-259. [PMID: 34221058 PMCID: PMC8216157 DOI: 10.4103/1735-5362.314823] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2020] [Revised: 10/15/2020] [Accepted: 03/17/2021] [Indexed: 11/04/2022] Open
Abstract
Background and purpose Neuropathic pain is one of the most common types of chronic pain that is very difficult to treat. Numerous studies have shown the potential role of vitamins in relieving both hyperalgesia and allodynia. Based on the convincing evidence, this study was designed to evaluate the possible antinociceptive effect of biotin on neuropathic pain in rats. Experimental approach This study was performed on male Sprague Dawley rats weighing 200-300 g. Neuropathic pain was induced by tying the sciatic nerve. Chronic constriction injury (CCI) of the sciatic nerve resulted in hyperalgesia and allodynia. To measure the thermal hyperalgesia, the plantar test was used. Also to evaluate the cold and mechanical allodynia, acetone test and von Frey test were applied. Biotin (4, 8, and 16 mg/kg) was administered orally as two different treatment regimens, acute and chronic. Findings/Results Acute oral administration of biotin (4, 8, and 16 mg/kg p.o.) on the 7th, 14th, and 21st postoperative days couldn't reduce pain sensitivity compared to the CCI group. However, following the oral administration of biotin (8 and 16 mg/kg p.o.) from the first day after the surgery until day 21, mechanical allodynia (P < 0.001) and heat hyperalgesia (P < 0.05) significantly relieved. Conclusion and implications Our results suggest that biotin can be considered as a potential therapeutic for the treatment of neuropathic pain, and supplementation with this vitamin could reduce the required doses of analgesic drugs. However, further studies are needed to confirm this hypothesis.

Dietary biotin deficiency decreased growth performance and impaired the immune function of the head kidney, spleen and skin in on-growing grass carp (Ctenopharyngodon idella). FISH & SHELLFISH IMMUNOLOGY 2020; 97:216-234. [PMID: 31857225 DOI: 10.1016/j.fsi.2019.12.033] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2019] [Revised: 12/06/2019] [Accepted: 12/13/2019] [Indexed: 06/10/2023]
Abstract
The aim of this study was to investigate the effects of dietary biotin deficiency on the growth performance and immune function of the head kidney, spleen and skin in on-growing grass carp (Ctenopharyngodon idella). A total of 540 on-growing grass carp (117.11 ± 0.48 g) were fed six diets containing increasing levels of biotin (0.012, 0.110, 0.214, 0.311, 0.427 and 0.518 mg/kg diet) for 70 days. Subsequently, a challenge experiment was performed by infecting them with Aeromonas hydrophila for six days. Our results showed that compared with the appropriate biotin level, (1) biotin deficiency (0.012 mg/kg diet) reduced the activities of lysozyme (LZ) and acid phosphatase (ACP), decreased the contents of complement 3 (C3), C4 and immunoglobulin M (IgM), as well as reduced the mRNA levels of antimicrobial peptides in the head kidney, spleen and skin of on-growing grass carp; (2) biotin deficiency reduced the mRNA levels of anti-microbial substances: liver-expressed antimicrobial peptide (LEAP) -2A, LEAP-2B, hepcidin, β-defensin-1 and mucin 2 in the head kidney, spleen and skin of on-growing grass carp; (3) biotin deficiency increased the mRNA levels of pro-inflammatory cytokines interleukin 1β (IL-1β), IL-6, IL-8, IL-12p40, IL-15, IL-17D, tumour necrosis factor α (TNF-α) and interferon γ2 (IFN-γ2) partially in association with nuclear factor-kappa B (NF-κB) signalling and reduced anti-inflammatory IL-4/13A, IL-10, IL-11 and transforming growth factor β1 (TGF-β1) mRNA levels partially in association with target of rapamycin (TOR) signalling in the head kidney, spleen and skin of on-growing grass carp. Interestingly, biotin deficiency had no effect on the expression of IL-12p35, IL-4/13B, TGF-β2, 4E-BP1 (skin only) or IKKα in the head kidney, spleen and skin of on-growing grass carp. In conclusion, the results indicated that biotin deficiency impaired the immune function of the head kidney, spleen and skin in fish. Finally, based on the percent weight gain (PWG), the ability to prevent skin haemorrhages and lesions, the LZ activity in the head kidney and the C4 content in the spleen, the optimal dietary biotin levels for on-growing grass carp (117-534 g) were estimated as 0.210, 0.230, 0.245 and 0.238 mg/kg diet, respectively.

Dietary Biotin Supplementation Modifies Hepatic Morphology without Changes in Liver Toxicity Markers. BIOMED RESEARCH INTERNATIONAL 2016; 2016:7276463. [PMID: 28105429 PMCID: PMC5220432 DOI: 10.1155/2016/7276463] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/07/2016] [Revised: 11/28/2016] [Accepted: 11/30/2016] [Indexed: 11/18/2022]
Abstract
Pharmacological concentrations of biotin have pleiotropic effects. Several reports have documented that biotin supplementation decreases hyperglycemia. We have shown that a biotin-supplemented diet increased insulin secretion and the mRNA abundance of proteins regulating insulin transcription and secretion. We also found enlarged pancreatic islets and modified islet morphology. Other studies have shown that pharmacological concentrations of biotin modify tissue structure. Although biotin administration is considered safe, little attention has been given to its effect on tissue structure. In this study, we investigated the effect of biotin supplementation on hepatic morphology and liver toxicity markers. Male BALB/cAnN Hsd mice were fed a control or a biotin-supplemented diet for 8 weeks. Versus the control mice, biotin-supplemented mice had an altered portal triad with dilated sinusoids, increased vascularity, and bile conducts. Furthermore, we observed an increased proportion of nucleomegaly and binucleated hepatocytes. In spite of the liver morphological changes, no differences were observed in the serum liver damage indicators, oxidative stress markers, or antioxidant enzymes. Our data demonstrate for the first time that biotin supplementation affects liver morphology in normal mice, and that these modifications are not paralleled with damage markers.

Abstract
Understanding the molecular mechanisms of vitamins has opened new perspectives regarding the relationship between nutritional signals and biological functions, which, in turn, has led to the development of new therapeutic agents. Although little is known about water-soluble vitamins as genetic modulators, evidence about their effects on gene expression has grown. In the case of biotin, besides its role as a carboxylase prosthetic group, it also affects gene expression and has a wide repertoire of effects on biological functions. Only recently, the role of pharmacological concentrations of biotin on systemic functions has attracted attention, and it is now being reconsidered with the help of new technologies. This novel approach could lead to new perspectives in its use as a therapeutic agent. The present review is focused on the effects of pharmacological concentrations of biotin on several biological functions and on the biotin signaling pathways that participate in gene expression.

Abstract
Holocarboxylase synthetase (HCS) catalyzes the covalent binding of biotin to carboxylases and histones. In mammals, the expression of HCS depends on biotin, but the mechanism of regulation is unknown. Here we tested the hypothesis that microRNA (miR) plays a role in the regulation of the HCS gene. Human embryonic kidney cells were used as the primary model, but cell lines from other tissues and primary human cells were also tested. In silico searches revealed an evolutionary conserved binding site for miR-539 in the 3 prime -untranslated region (3 prime -UTR) of HCS mRNA. Transgenic cells and reporter gene constructs were used to demonstrate that miR-539 decreases the expression of HCS at the level of transcription rather than translation; these findings were corroborated in nontransgenic cells. When miR-539 was overexpressed in transgenic cells, the abundance of both HCS and biotinylated histones decreased. The abundance of miR-539 was tissue dependent: fibroblasts gt kidney cells gt intestinal cells gt lymphoid cells. Dose-response studies revealed that the abundance of miR-539 was significantly higher at physiological concentrations of biotin than both biotin-deficient and biotin-supplemented media in all cell lines tested. In kidney cells, the expression of HCS was lower in cells in physiological medium than in deficient and supplemented medium. In contrast, in fibroblasts, lymphoid cells, and intestinal cells, there was no apparent link between miR-539 abundance and HCS expression, suggesting that factors other than miR-539 also contribute to the regulation of HCS expression in some tissues. Collectively, the results of this study suggest that miR-539 is among the factors sensing biotin and regulating HCS.

Abstract
The following proteins are candidates for maintaining biotin homeostasis in humans: the biotin transporters sodium-dependent multivitamin transporter (SMVT) and monocarboxylate transporter 1, the biotinyl-protein ligase holocarboxylase synthetase (HCS), and the lysine-epsilon-biotin hydrolase biotinidase. Liver cells are supplied through the portal vein with high levels of water-soluble vitamins compared with those of peripheral tissues. We hypothesized that the mechanisms of biotin homeostasis are qualitatively and quantitatively different in cells derived from human liver (HepG2 cells) and lymphoid tissues (Jurkat cells). Cells were cultured in biotin-defined media, representing deficient (D), normal (N), and supplemented (S) individuals. Biotinylation of carboxylases depended on biotin availability in both cell types, but HepG2 cells required 3 times more biotin than Jurkat cells to maintain normal levels of holocarboxylases. The expression of biotin transporters was less in both types in medium S compared with cells in media D and N; in contrast, the expression of HCS was higher in cells in medium S compared with the other cells. The abundance of 3-methylcrotonyl-CoA carboxylase mRNA was lower in cells in medium D than cells in media N and S. The enrichment of biotinylated histones was higher at the SMVT promoter 1 in HepG2 and Jurkat cells in medium S compared with the corresponding cells in media D and N, presumably repressing the SMVT gene. The mechanisms of biotin homeostasis are qualitatively similar but quantitatively different in HepG2 and Jurkat cells; HCS, histone biotinylation, and biotin transporters play a role in homeostasis in both.
