Trehalose attenuates abdominal aortic aneurysm formation by inducing autophagy in smooth muscle cells
Trehalose attenuates abdominal aortic aneurysm formation by inducing autophagy in smooth muscle cells
 BACKGROUND  Trehalose is a naturally occurring disaccharide, which has been identified as an autophagy inducer and exhibits protective effect in cardiovascular diseases such as myocardial infraction and atherosclerosis. However, the functional role of trehalose in abdominal aortic aneurysm (AAA) remains undefined.  METHODS  To study the effect of trehalose in AAA, trehalose (1 g/kg per day) were given for 14 continuous days in a mouse model of elastase-induced abdominal aortic aneurysm. On day 14, ultrasound was performed to measure aortic diameter before the abdominal aortas were harvested and processed for further analysis. Verhoeff-Van Gieson staining and TUNEL staining were performed on paraffin sections to evaluate vascular histology and apoptosis, immunofluorescence staining and Western-blot were performed to evaluate expression of autophagy markers.  RESULTS  Echocardiography and in situ pictures demonstrated that trehalose attenuated infrarenal aorta dilation. Verhoeff-Van Gieson staining showed elastin degradation was improved in trehalose-treated group. Compared with vehicle-treated mice, trehalose treatment restored smooth muscle cell contractile phenotype with increased α-SMA, Calponin and Myh11 expression. Furthermore, trehalose also attenuated cell apoptosis and leukocytes infiltration. Importantly, trehalose induced autophagy with decrease SQSTM1/p62 accumulation, increased lamp2 expression and LC3B conversion.  CONCLUSION  Trehalose attenuated AAA progression with decreased inflammation and restored SMC contractile phenotype by inducing autophagy. These results demonstrated the therapeutic potential of trehalose in AAA.

Combined treatment with glucosamine and chondroitin sulfate improves rheumatoid arthritis in rats by regulating the gut microbiota | Nutrition & Metabolism | Full Text
Combined treatment with glucosamine and chondroitin sulfate improves rheumatoid arthritis in rats by regulating the gut microbiota | Nutrition & Metabolism | Full Text
Background To investigate the ameliorative effects of glucosamine (GS), chondroitin sulphate (CS) and glucosamine plus chondroitin sulphate (GC) on rheumatoid arthritis (RA) in rats, and to explore the mechanism of GS, CS and GC in improving RA based on the gut microbiota. Methods RA rat models were effectively developed 14 days after CFA injection, and then garaged with GS, CS and GC. Body weight and paw volume of rats were monitored at multiple time points at the beginning of CFA injection. Until D36, serum and ankle tissue specimens were used to measure levels of circulating inflammatory factors (TNF-α, IL-1β, MMP-3, NO and PGE2) and local inflammatory indicators (TLR-4 and NF-κB). On D18, D25, and D36, intergroup gut microbiota was compared using 16S rRNA gene sequencing and bioinformatics analysis. We also performed the correlation analysis of gut bacteria, joint swelling and inflammatory indicators. Results GC, rather than GS and CS, could reduce right paw volumes, levels of TLR-4 and NF-κB in synovial tissues. In addition, enriched genera in RA model rats screened out by LEfSe analysis could be inhibited by GC intervention, including potential LPS-producing bacteria (Enterobacter, Bacteroides, Erysipelotrichaceae_unclassified and Erysipelotrichaceae_uncultured) and some other opportunistic pathogens (Esherichia_Shigella, Nosocomiicoccus, NK4A214_group, Odoribacter, Corynebacterium and Candidatus_Saccharimonas.etc.) that positively correlated with pro-inflammatory cytokines, right paw volume, and pathology scores. Furthermore, the gut microbiota dysbiosis was observed to recover before alleviating joint swelling after interventions. Conclusions GC could inhibit potential LPS-producing bacteria and the activation of TLR-4/NF-κB pathway in RA rats, thus alleviating RA-induced joint injury.

Risk Of Ischaemic Stroke Among New Users Of Glucosamine And Chondroitin Sulphate: A Nested Case-Control Study. - Osteoarthritis and Cartilage
Purpose: SYSADOAs (symptomatic slow-acting drugs for osteoarthritis) are a heterogeneous group of drugs that have the ability to modify the symptoms of osteoarthritis (OA) slowly and independently of NSAIDs, analgesics or any other therapeutic option. The main drugs included in this group are glucosamine (sulphate or hydrochloride) (GS) and chondroitin sulphate (CS), widely prescribed for the treatment of OA in some countries. Although the efficacy of GS and CS for the treatment of OA remains controversial, several human, animal and laboratory studies have suggested that both drugs show anti-inflammatory properties that could reduce the risk of several diseases.

Analyzing the Prebiotic Potential of Glucosamine for Targeting the Gut Microbiome Health
Analyzing the Prebiotic Potential of Glucosamine for Targeting the Gut Microbiome Health
Recognizing the composition and modulation of the microbiome, a viable therapeutic tool for multi-targeted therapy is a new strategy that has recently been explored. Glucosamine (GS) is being studied for its prebiotic potential in addition to being the most abundant and naturally occurring amino monosaccharide. The current study focuses on glucosamine’s prebiotic potential by assessing the stability of various GS concentrations (1% - 5%) in the gastrointestinal tract (GIT) and its ability to be fermented by the gut microbiota. The results showed that GS stimulated the most growth in L. acidophilus even after a longer incubation time than B. bifidum and L. acidophilus growth was concentration-dependent, with maximum growth at 3% with a simultaneous decrease in pH (5.6 - 1.7). The decrease in GS concentration with time also represented the growth of bacterial species, demonstrating the species’ utilization of GS. Furthermore, at 3%, GS also represented the prebiotic index of 1.9. In addition, the concentration of GS in various simulated GIT fluids was estimated in both fast and fed conditions to examine GS stability at various levels in the gut. The results showed that GS remained unaffected and non-digestible in all of the simulated GIT fluids (salivary, gastric, intestinal, and colonic), but there was a slight decrease in GS concentration (2.8%) in the fasted state of gastric fluid due to low pH levels (1.6). As a result, the findings are conclusive and suggest that GS possesses prebiotic properties.

Toll-like receptor 9 is involved in the induction of galectin-9 protein by dietary anti-allergic compound fucoidan
Toll-like receptor 9 is involved in the induction of galectin-9 protein by dietary anti-allergic compound fucoidan
Dietary intervention of fucoidan extracted from Saccharina japonica brown seaweed has been ascertained to favor an increase of galectin-9 protein in the intestine of allergic mice, resulting in the attenuation of the food allergy symptoms. The molecular mechanism underpinning that galectin-9 secretion remains unclear. Recently, some evidence has suggested an implication of Toll-like receptor 9 (TLR9) in galectin-9 secretion. However, no investigation has been done. For this study, we aimed to understand the relationship between galectin-9 production and fucoidan intake, which will improve the therapeutic use of fucoidan in allergy treatment. Intestinal epithelial cells (IECs) were cultured in solid or transwell plates and apically exposed to fucoidan solutions and/or synthetic TLR9 agonist (CpG-ODN). The transcriptional response of the cells to galectin-9 (lgals9) and the TLR9 gene was evaluated by using q-RTPCR, and the protein expression of galectin-9 was analyzed by conducting an ELISA test. Knockdown of TLR9 in IECs was performed by targeting TLR9 siRNA, and its effect on galectin-9 release was assessed. We found that the interaction of fucoidan and IECs resulted in the upregulation of galectin-9 released in a dose- and time-dependent manner. The increase was further potentiated in combination with the TLR9 agonist. Fucoidan exposure to IECs tended to increase the mRNA expression of TLR9 in a way similar to that of the TLR9 agonist effect, and knockdown of TLR9 in IECs resulted in a decreased tendency of fucoidan-induced galectin-9 protein. TLR9 activation is therefore involved in the increased release of galectin-9 protein observed in IECs upon fucoidan exposure.

The role of type 2 diabetes in the association between habitual glucosamine use and dementia a prospective cohort study Alzheimer's Research & Therapy Full Text
Background Growing evidence has showed an association between habitual glucosamine use and type 2 diabetes (T2D). However, the effect of habitual glucosamine use on risk of dementia remains poorly understood. Our study aimed to examine the association between glucosamine use and risk of dementia and further to identify the mediating role of T2D in the association. Methods A total of 495,942 participants from UK Biobank who completed a questionnaire on habitual glucosamine use were included at baseline (2006–2010) and then followed up for incidence of dementia until 2020. Cox proportional hazard regressions were performed to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for incident dementia. Markov multi-state models were used to explore the role of incidence of T2D during the follow-up in the association. Results Overall, 18.80% of the participants reported habitual use of glucosamine at baseline. A total of 6831 dementia events were recorded during a median follow-up of 11 years. In fully adjusted models, habitual glucosamine use was associated with a significantly lower risk of dementia (HR = 0.87, 95% CI: 0.82–0.93). Multi-state models showed that the association between glucosamine use and dementia was mediated by the incidence of T2D during the follow-up (HR of dementia without T2D: 0.92, 95% CI: 0.86–0.99; HR of post-T2D dementia: 0.79, 95% CI: 0.67–0.93). Conclusions Our findings reveal that habitual use of glucosamine supplement is associated with a lower risk of dementia, which might be explained by incidence of T2D.
