Abstract
The importance of β-glucan from S. cerevisiae in angiogenesis has not been well studied. We investigated whether β-glucan induces angiogenesis through PI3K/Src and ERK1/2 signaling pathway in HUVECs. We identified that β-glucan induced phosphorylation of PI3K, Src, Akt, eNOS, and ERK1/2. Subsequently, we found that this phosphorylation increased the viability of HUVECs. We also observed that stimulation of β-glucan promoted the activity of MEF2 and MEF2-dependent pro-angiogenic genes, including EGR2, EGR3, KLF2, and KLF4. Additionally, the role of β-glucan in angiogenesis was confirmed using in vitro and ex vivo experiments including cell migration, capillary-like tube formation and mouse aorta ring assays. To determine the effect of β-glucan on the PI3K/Akt/eNOS and ERK1/2 signaling pathway, PI3K inhibitor wortmannin and ERK1/2 inhibitor SCH772984 were used. Through the Matrigel plug assay, we confirmed that β-glucan significantly increased angiogenesis in vivo. Taken together, our study demonstrates that β-glucan promotes angiogenesis via through PI3K and ERK1/2 signaling pathway.

Tailor R, Medara N, Chopra A, Swarnamali H, Eberhard J, Jayasinghe TN. Role of prebiotic dietary fiber in periodontal disease: A systematic review of animal studies. Front Nutr 2023; 10:1130153. [PMID: 36998913 PMCID: PMC10043215 DOI: 10.3389/fnut.2023.1130153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Accepted: 02/21/2023] [Indexed: 03/16/2023] Open
Abstract
BackgroundPeriodontitis is a chronic inflammatory condition affecting the supporting structures of a tooth in the oral cavity. The relationship between dietary fiber and periodontitis is poorly understood. The objective of this systematic review is to investigate if an intake of dietary fiber modulates periodontal disease in animal models and any concomitant effects on systemic inflammation, microbiota and their metabolites.MethodsAnimal studies using periodontitis models with any form of fiber intervention were included. Studies with comorbidities that were mutually inclusive with periodontitis and animals with physiological conditions were excluded. Search strategy with MeSH and free-text search terms were finalized and performed on the 22nd of September 2021.CINAHL Complete, EMBASE, MEDLINE, SciVerse Scopus® and Web of Science Core Collection databases were used to identify studies. SYRCLE’s risk of bias tool and CAMARADES were used for quality assessment. Results were synthesized utilizing Covidence© web-based platform software to remove duplicates, and the remaining studies were manually filtered.ResultsA total of 7,141 articles were retrieved from all databases. Out of 24 full-text articles assessed for eligibility, four studies (n = 4) were included. Four studies involved the use of β-(1,3/1,6)-glucan (n = 3) and mannan oligosaccharide (n = 1) at differing dosages for different study durations. All studies utilized a ligature-induced model of periodontitis in rats, either Wistar (n = 3) or Sprague–Dawley (n = 1). A dose-dependent relationship between the increased fiber intake and decrease in alveolar bone loss and pro-inflammatory markers was observed.ConclusionThe number of included studies is limited and narrow in scope. They highlight the importance of pre-clinical trials in this field with broader dietary fiber intervention groups before proceeding to clinical trials. The use of dietary fiber as an intervention shows promise in the reduction of inflammatory conditions like periodontitis. However, further research is required to delineate the relationship between diet and its effects on microbiota and their metabolites such as short chain fatty acids in animal models of periodontitis.

Li Q, Ouyang X, Lin J. The impact of periodontitis on vascular endothelial dysfunction. Front Cell Infect Microbiol 2022; 12:998313. [PMID: 36118034 PMCID: PMC9480849 DOI: 10.3389/fcimb.2022.998313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 08/15/2022] [Indexed: 11/26/2022] Open
Abstract
Periodontitis, an oral inflammatory disease, originates from periodontal microbiota dysbiosis which is associated with the dysregulation of host immunoinflammatory response. This chronic infection is not only harmful to oral health but is also a risk factor for the onset and progress of various vascular diseases, such as hypertension, atherosclerosis, and coronary arterial disease. Vascular endothelial dysfunction is the initial key pathological feature of vascular diseases. Clarifying the association between periodontitis and vascular endothelial dysfunction is undoubtedly a key breakthrough for understanding the potential relationship between periodontitis and vascular diseases. However, there is currently a lack of an updated review of their relationship. Therefore, we aim to focus on the implications of periodontitis in vascular endothelial dysfunction in this review.
