Amaral AR, Risolia LW, Rentas MF, Marchi PH, Balieiro JCDC, Vendramini THA, Brunetto MA. Translating Human and Animal Model Studies to Dogs' and Cats' Veterinary Care: Beta-Glucans Application for Skin Disease, Osteoarthritis, and Inflammatory Bowel Disease Management. Microorganisms 2024; 12:1071. [PMID: 38930453 PMCID: PMC11205328 DOI: 10.3390/microorganisms12061071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Revised: 05/23/2024] [Accepted: 05/24/2024] [Indexed: 06/28/2024] Open
Abstract
The inclusion of beta-glucans in dog and cat food is associated with numerous beneficial effects on the health of these animals. In this regard, there is an effort to elucidate the potential of this nutraceutical in chronic patients. Since there is a lack of a review on the topic, this review article aims to compile and discuss the evidence found to date. Atopic dermatitis, inflammatory bowel disease, and osteoarthritis are diseases of significant clinical relevance in dogs and cats. In general, the pathophysiology of these chronic conditions is related to immune-mediated and inflammatory mechanisms. Therefore, the immunomodulation and anti-inflammatory effects of beta-glucans are highlighted throughout this review. The available information seems to indicate that the studies on beta-glucans' impact on allergic processes in dogs indicate a reduction in clinical signs in atopic dermatitis cases. Additionally, while beta-glucans show promise as a safe supplement, particularly for osteoarthritis, further clinical trials are imperative, especially in uncontrolled environments. Beta-glucans emerge as a potential nutraceutical offering immune benefits for inflammatory bowel disease patients, although extensive research is required to define its optimal origin, molecular weight, dosage, and specific applications across animals suffering from this disease.

Int J Mol Sci 2023; 24:14773. [PMID: 37834221 PMCID: PMC10572787 DOI: 10.3390/ijms241914773] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 09/27/2023] [Accepted: 09/27/2023] [Indexed: 10/15/2023] Open
Abstract
Ulcerative colitis (UC), a subtype of inflammatory bowel disease, is a chronic gastrointestinal inflammatory disease with unclear etiology and pathophysiology. Herein, we determined the effects of extracellular polysaccharides purified from Aureobasidium pullulans SM-2001 (Polycan) on tight junction protein expression, inflammation, and apoptosis in a dextran sodium sulfate (DSS)-induced acute colitis model. Fifty mice were divided into normal, DSS, DSS + Polycan 250 mg/kg (Polycan 250), DSS + Polycan 500 mg/kg (Polycan 500), and DSS + 5-aminosalicylic acid 100 mg/kg (5-ASA) groups. Their body weights, colon lengths, histological changes in colon tissue, and tight junction function were observed. Results showed that Polycan 250, Polycan 500, and 5-ASA significantly inhibited body weight loss compared with DSS. Similar to 5-ASA, Polycan 500 exhibited preventive effects on colon length shortening and histological changes in colon tissues. Polycan inhibited the DSS-induced decrease in fluorescein isothiocyanate-dextran permeability and myeloperoxidase activity. Moreover, Polycan significantly recovered serum cytokine (e.g., tumor necrosis factor-α, interleukin (IL)-6, and IL-1β) or mRNA expression in colon tissue compared with DSS. Polycan also inhibited apoptosis by reducing caspase-3 activity and the Bcl-2 associated X/B-cell lymphoma 2 (Bcl-2) ratio. Additionally, DSS treatment significantly reduced microbial abundance and diversity, but the administration of Polycan reversed this effect. Collectively, Polycan protected intestinal barrier function and inhibited inflammation and apoptosis in DSS-induced colitis.

Abstract
Abstract
Background
Duchenne muscular dystrophy is a hereditary muscular disease involving degeneration (i.e. atrophy and loss of muscle fibres) of skeletal muscles, including the diaphragm, and progressively severe functional decline. A previous study shows Polycan, a type of β-glucan derived from the black yeast Aureobasidium pullulans (SM-2001), promotes osteogenicity and bone loss, and possesses anti-inflammatory activity to induce inflammatory cytokines in human immune and cancer cells.
Objective
In this study, we evaluated changes in exercise load behaviour measurements and changes in muscle-related physiological indicators following oral administration of Polycan in mdx mice, an experimental animal model of Duchenne muscular dystrophy.
Result
In mdx mice, Polycan prevented weight loss and thickness of skeletal muscle. In addition, by monitoring increases in running time of mice on treadmills and performing a grip strength test, we confirmed reduced muscle function was recovered to some extent after administering Polycan to mdx mice. In addition, we confirmed that Polycan significantly altered mRNA expression in a concentration-dependent manner, whereby myogenic transcription factors (MyoD, Myf5 and Myogenin) increased and FoxO3α, MuRF1 and Atrogin-1 decreased. We aimed to investigate the mechanism of action in Polycan on energy metabolism of p-AMPK, SIRT1 and PGC1α with apoptosis expression levels as factors related to signalling pathways. Expression ratios of cleaved-caspase-3/caspase-3 and Bax/Bcl-2 in the Polycan extract-administered group increased compared with the control group.
Conclusion
These results demonstrate that Polycan can improve and protect muscle atrophy by preventing apoptosis via pathway regulation related to myogenic transcription factors and energy metabolism in mdx mice.

Abstract
Balneotherapy is a common non-pharmacological treatment for osteoarthritis (OA), however, the efficacy is controversial in knee OA. Jeju magma-seawater (JMS) has high contents of various minerals, which has anti-inflammatory and antioxidant properties via an oral route. Thus, we examined the effects of JMS bathing on knee OA and the combination effects with diclofenac sodium as an anti-inflammatory drug. Knee OA was induced by transection of the anterior cruciate ligament and the partial meniscectomy in rat. The rats were administered subcutaneously saline or diclofenac sodium in saline, followed by bathing in thermal distilled water or JMS for 8 weeks. The model represented the characteristic changes of the cartilage degradation, osteophyte formation and synovial inflammation, and the relevant symptoms of the joint swelling and stiffness. However, the JMS bathing reduced the joint thickness and improved the mobility. It also contributed to a well-preserved tissue supported by increases in bone mineral density of the joint and decreases in Mankin scores in the cartilages. The effects involved anti-inflammation, chondroprotection, anti-apoptosis, and chondrogenesis. Overall, the JMS bathing in combination with diclofenac sodium showed a similar trend associated with synergic effects. It suggests that JMS bathing can be promising for a clinical use in knee OA.

Abstract
In this study, we aimed to determine the synergistic effects of a formula consisting of dried pomegranate concentrate powder, Eucommiae Cortex, and Achyranthis Radix 5:4:1 (g/g) (PCP:EC:AR) in a surgically induced osteoarthritis (OA) rabbit model. PCP:EC:AR was orally administered once per day. Knee thickness, maximum extension of the knee joint, gross articular defect area, and the histopathological appearance of the cartilage were monitored, along with serum collagen type II C-telopeptide (CTX-II), cartilage oligomeric matrix protein (COMP), matrix metalloproteinase (MMP)-3, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and subchondral IL-1β and TNF-α levels. Roentgenographic images were also evaluated. PCP:EC:AR significantly inhibited the surgically induced increase in knee thickness, maximum extension of both knees, knee thickness after capsule exposure, gross femoral and tibial articular defect areas, loss of the knee joint area, serum and synovial COMP, CTX-II, and MMP expression, and synovial IL-1β, and TNF-α expression. In addition, surgically induced narrowing of the knee bones, loss of the joint area, cartilage damage, and osteophyte formation were reduced. PCP:EC:AR suppressed the surgically induced increases in the Mankin score, and subchondral IL-1β and TNF-α immunolabeled cell numbers. PCP:EC:AR exerted potent OA protective effects in a surgically induced OA rabbit model.

Abstract
We examined the antiosteoarthritis effect of a mixture of powdered pomegranate concentrate, eucommiae cortex, and achyranthis radix (5:4:1 w/w) (PEA-Mix). After the injection of monosodium iodoacetate (MIA), PEA-Mixs were orally administered. To assess pain-related behaviors, a von Frey filament test and open field test were performed. We also examined the knee thickness, maximum knee extension angle, bone mineral density (BMD), and compressive strength of the knee joint and performed a histopathologic analysis. The number of COX-2, tumor necrosis factor (TNF)-α, poly (ADP-ribose) polymerase (PARP), and 5-bromo-2′-deoxyuridine immunoreactive cells, the prostaglandin E2 (PGE2) and 5-lipoxygenase (LPO) levels, matrix metalloproteinase (MMP) activity, and mRNA levels of chondrogenesis-related genes were analyzed. PEA-Mix significantly inhibited the MIA-induced decrease in the paw-withdrawal threshold and total distance moved, and the MIA-induced increases in the maximum knee extension angle and knee thickness. Also, the MIA-induced loss of the knee joint articular surface region and decrease in the BMD were significantly suppressed by PEA-Mix. The MIA-induced increases in the 5-LPO, PGE2, MMP-2, MMP-9, COX-2, and TNF-α mRNA levels were reduced by PEA-Mix. PEA-Mix increased the MIA-mediated reduction in the SOX-9 and aggrecan mRNA levels. The number of PARP-positive cells was smaller in PEA-Mix-administered rats than in MIA-administered rats, while the number of 5-bromo-2′-deoxyuridine-positive cells was larger. Therefore, PEA-Mix relieved the MIA-induced pain-related behaviors, chondrocyte proliferation, and anti-inflammatory activity.

Abstract
This study was performed to investigate the effects of highly bioavailable curcumin as Theracurmin® (TC) in rats with monosodium iodoacetate (MIA)-induced osteoarthritis (OA). Seventy-seven male Wistar rats were divided into six groups: normal, negative control (MIA only), positive control (Cerebrex), and three experimental groups treated with 500, 1300, or 2600 mg/kg of TC for 5 weeks. MIA injection-induced OA caused 30% weight-bearing imbalance whereas weight bearing imbalance was significantly improved in the TC groups. Mankin scores revealed TC treatment had significantly ameliorated cartilage damage and chondrocyte decrease. The expressions of nitrotyrosine, tumor necrosis factor-α, phosphorylated nuclear factor kappa B cells, and cleaved caspase-3 were markedly increased in rat with MIA-induced OA, but the TC-treated groups exhibited a significant reduction in the number of immunoreactive cells in a dose-dependent manner. In conclusion, administration of TC contributes to the anti-arthritic effect in rat with MIA-induced OA.

A Double-Blind, Randomized Controlled 12-Week Follow-Up Trial to Evaluate the Efficacy and Safety of Polycan in Combination with Glucosamine for the Treatment of Knee Osteoarthritis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:9750531. [PMID: 31341505 PMCID: PMC6612958 DOI: 10.1155/2019/9750531] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Revised: 04/14/2019] [Accepted: 05/14/2019] [Indexed: 12/03/2022]
Abstract
Aim The aim of the present study was to examine the efficacy and safety of Polycan, a β-glucan produced from the black yeast Aureobasidium pullulans SM-2001, in combination with glucosamine in reducing knee osteoarthritis-associated symptoms. Methods This was a double-blind, randomized controlled trial of a formulated product composed of 16.7 mg of Polycan and 250 mg of glucosamine (Group A), 16.7 mg of Polycan and 500 mg of glucosamine (Group B), or 500 mg of glucosamine (control group) per capsule, administered as three capsules once per day over a period of 12 weeks, conducted with 100 osteoarthritis patients, aged 35–80 years. The primary outcome measure was osteoarthritis symptoms assessed by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. The secondary outcome measures included rescue medication use (according to data from a patient-reported diary) and other safety indices (body weight, blood pressure, hematological, and biochemistry markers). Results Compared with the control group, Group B demonstrated a statistically significant reduction in the total WOMAC score after 12 weeks of treatment (p < 0.05). There was a significant reduction in the frequency of rescue medication used in Groups A and B compared with the control group (p < 0.05). There were no significant changes in hematology and biochemistry parameters or health indices between the active and the control group. Conclusion Among patients with mild or moderate osteoarthritis, a daily oral dose of Polycan (50 mg) in combination with glucosamine (750 mg or 1500 mg; Group A or B, respectively) resulted in a better treatment outcome than treatment with glucosamine (1500 mg) alone.

Anti-osteoporotic effects of mixed compositions of extracellular polymers isolated from Aureobasidium pullulans and Textoria morbifera in ovariectomized mice. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 18:295. [PMID: 30400922 PMCID: PMC6220464 DOI: 10.1186/s12906-018-2362-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Accepted: 10/25/2018] [Indexed: 12/26/2022]
Abstract
Background Extracellular polymeric substances isolated from Aureobasidium pullulans (EAP), containing specifically 13% β-1,3/1,6-glucan, have shown various favorable bone-preserving effects. Textoria morbifera Nakai (TM) tree has been used as an ingredient in traditional medicine and tea for various pharmacological purposes. Thus, the present study was aimed to examine the synergistic anti-osteoporotic potential of mixtures containing different proportions of EAP and TM compared with that of the single formulations of each herbal extract using bilateral ovariectomized (OVX) mice, a renowned rodent model for studying human osteoporosis. Methods Thirty five days after bilateral-OVX surgery, 9 combinations of EAP:TM (ratios = 1:1, 1:3, 1:5, 1:7, 1:9, 3:1, 5:1, 7:1, 9:1) and single separate formulations of EAP or TM were supplied orally, once a day for 35 days at a final concentration of 200 mg/kg. Variations in body weight gains during the experimental periods, as well as femur weights, bone mineral density (BMD), bone strength (failure load), and mineral content (calcium [Ca] and inorganic phosphorus [IP]) following sacrifice were measured. Furthermore, histomorphometric and histological profile analyses of serum biochemical parameters (osteocalcin content and bone specific alkaline phosphatase [bALP] activity) were conducted following sacrifice. Femurs histomorphometric analyses were also conducted for bone resorption, structure and mass. The results for the mixed formulations of EAP:TM and separate formulations were compared with those of risedronate sodium (RES). Results The EAP:TM (3:1) formulation synergistically enhanced the anti-osteoporotic potential of individual EAP or TM formulations, possibly due to enhanced variety of the active ingredients. Furthermore, the effects of EAP:TM were comparable to those of RES (2.5 mg/kg) treatment. Conclusion The results of this study suggest that, the EAP:TM (3:1) combination might act as a new pharmaceutical agent and/or health functional food substance for curing osteoporosis in menopausal women.

Abstract
β-Glucans are a group of biologically-active fibers or polysaccharides from natural sources with proven medical significance. β-Glucans are known to have antitumor, anti-inflammatory, anti-obesity, anti-allergic, anti-osteoporotic, and immunomodulating activities. β-Glucans are natural bioactive compounds and can be taken orally, as a food supplement, or as part of a daily diet, and are considered safe to use. The medical significance and efficiency of β-glucans are confirmed in vitro, as well as using animal- and human-based clinical studies. However, systematic study on the clinical and physiological significance of β-glucans is scarce. In this review, we not only discuss the clinical and physiological importance of β-glucans, we also compare their biological activities through the existing in vitro and animal-based in vivo studies. This review provides extensive data on the clinical study of β-glucans.
