Abstract
Carotenoids have anti-inflammatory and antioxidant properties, being a potential bioactive compound for gut health. The objective of this systematic review was to investigate the effects of carotenoids on gut microbiota, gut barrier, and inflammation in healthy animals. The systematic search from PubMed, Scopus, and Lilacs databases were performed up to March 2023. The final screening included thirty studies, with different animal models (mice, rats, pigs, chicks, drosophila, fish, and shrimp), and different carotenoid sources (β-carotene, lycopene, astaxanthin, zeaxanthin, lutein, and fucoxanthin). The results suggested that carotenoids seem to act on gut microbiota by promoting beneficial effects on intestinal bacteria related to both inflammation and SCFA production; increase tight junction proteins expression, important for reducing intestinal permeability; increase the mucins expression, important in protecting against pathogens and toxins; improve morphological parameters important for digestion and absorption of nutrients; and reduce pro-inflammatory and increase anti-inflammatory cytokines. However, different carotenoids had distinct effects on gut health. In addition, there was heterogeneity between studies regarding animal model, duration of intervention, and doses used. This is the first systematic review to address the effects of carotenoids on gut health. Further studies are needed to better understand the effects of carotenoids on gut health.

Alginate Oligosaccharides Prevent Dextran-Sulfate-Sodium-Induced Ulcerative Colitis via Enhancing Intestinal Barrier Function and Modulating Gut Microbiota. Foods 2023; 12:foods12010220. [PMID: 36613442 PMCID: PMC9818813 DOI: 10.3390/foods12010220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 12/22/2022] [Accepted: 12/27/2022] [Indexed: 01/05/2023] Open
Abstract
Alginate oligosaccharides are degradation products of alginate and have attracted increasing attention due to their versatile biological functions. In the present study, C57BL/6 mice were used to assess the ameliorative effects and mechanisms of guluronate oligosaccharides (GAOS), mannuronic oligosaccharides (MAOS), and heterozygous alginate oligosaccharides (HAOS), which are the three alginate oligosaccharides of dextran sulfate sodium (DSS)-induced ulcerative colitis. The study showed that alginate oligosaccharides alleviated pathological histological damage by slowing down weight loss, inhibiting colonic length shortening, and reducing disease activity index (DAI) and histopathological scores. Alginate oligosaccharides modulated the colonic inflammatory response by reducing colonic MPO levels and downregulating the expression of IL-6 and IL-1β. Alginate oligosaccharides reduced intestinal permeability and reversed intestinal barrier damage by increasing the number of goblet cells, decreasing LPS levels, downregulating Bax protein levels, upregulating Bcl-2 protein levels, and enhancing the expression of the E-cadherin. Furthermore, alginate oligosaccharides modulated the composition of the gut microbiota and restored the production of short-chain fatty acids (SCFAs), especially acetate and butyrate. In conclusion, our study provides a scientific basis for the role of alginate oligosaccharides in relieving ulcerative colitis.

Triacylglycerol rich in docosahexaenoic acid regulated appetite via the mediation of leptin and intestinal epithelial functions in high-fat, high-sugar diet-fed mice. J Nutr Biochem 2021; 99:108856. [PMID: 34517098 DOI: 10.1016/j.jnutbio.2021.108856] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 04/25/2021] [Accepted: 08/10/2021] [Indexed: 12/13/2022]
Abstract
High-fat, high-sugar diet (HFHS) induced leptin resistance and intestinal epithelial dysfunction is implicated in hyperphagia and metabolic disorders. Numerous studies have demonstrated the efficacy of dietary interventions for reducing appetite. This study aims to investigate whether triacylglycerol rich in DHA (DHA-TG) could regulate appetite in mice fed with a HFHS diet and the mechanism by which it achieves that. DHA-TG could reduce food intake and regulate neuropeptides (POMC, AgRP, and NPY) expression in HFHS diet-fed mice. Hypothalamic transcriptome analysis reveals that these effects might be attributed to the role of DHA-TG in modulating hormone secretion and digestive system process. According to ELISA and RT-qPCR analysis, DHA-TG ameliorated leptin secretion and attenuated central leptin resistance induced by HFHS diet feeding. Besides, DHA-TG prevented the damage of intestinal epithelial barrier in nutritive obese mice by improving leptin sensitivity. Based on jejunal transcriptome analysis, DHA-TG also protected intestinal endocrine function, especially the secretion of another anorectic hormone, cholecystokinin (CCK), in HFHS diet-fed mice. Furthermore, DHA-TG was ineffective in repressing appetite, and improving gut leakage in leptin-deficient mice (ob/ob mice). In conclusion, DHA-TG has a potential to regulate appetite with the action of leptin, and intestinal epithelial functions in HFHS diet-fed mice.

Identification of curcumin as a potential α-glucosidase and dipeptidyl-peptidase 4 inhibitor: Molecular docking study, in vitro and in vivo biological evaluation. J Food Biochem 2021; 46:e13686. [PMID: 33817806 DOI: 10.1111/jfbc.13686] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 02/09/2021] [Accepted: 02/15/2021] [Indexed: 12/13/2022]
Abstract
Natural compounds have tremendous potential to regulate glucose metabolism, but conventional methods for studying their bioactivities are usually labor intensive. Here, hypoglycemic properties in 22 selected food-derived compounds were examined using molecular docking. The results indicated that curcumin is an inhibitor of both α-glucosidase and dipeptidyl-peptidase 4 (DPP-4), which are important for glycemic control. These effects of curcumin were also confirmed by enzymatic determination in vitro. Furthermore, curcumin significantly improved diet-induced hyperglycemia (e.g., fasting plasma glucose levels and glycogen storage in muscle or liver) in mice. This might be attributed to its inhibitory effects on the activities of α-glucosidase and DPP-4 in vivo. Curcumin also upregulated the expression of genes (e.g., glucagon-like peptide 1) related to DPP-4 activity in the small intestine. In conclusion, curcumin is a potential ingredient of functional foods used for diet-induced hyperglycemia management. PRACTICAL APPLICATIONS: Curcumin has been widely used as a colorant in the food industry. Moreover, a growing number of studies have described its diverse biological functions, such as anti-inflammatory, anti-oxidant, and anti-angiogenic activities. Thus, curcumin is regarded as a potential ingredient in functional foods. Our results highlighted the hyperglycemic effect of curcumin, suggesting that curcumin may be included in food products for hyperglycemic patients.

Abstract
This study aims to understand the treatment of stomach ulcers with FLD and to identify its potential target genes as well as related pathways by transcriptomic analysis. Rat stomach mRNA from a blank group (BG), a model group (MG), an untreated-model group (u-MG), and a treated group (TG) was sequenced. A partial least-squares discriminant analysis (PLS-DA) was used to differentiate the MG from the BG, and the Deseq2 R Package was used to identify differentially expressed genes between these groups. Furthermore, t-tests based on transcripts per million (TPM) were used to select different genes between MG and BG and significantly retrieved genes in TG, except for self-retrieved genes in u-MG. Finally, pathways regulated by retrieved genes were analyzed with KEGG database. Results showed that 327 of the 32,623 total detected genes were different (p < 0.05) between the MG and BG. Among these genes, eighteen genes were significantly retrieved after rats were treated with FLD in TG, and they were considered as target genes on which FLD acted. In conclusion, FLD was deduced to cure stomach ulcers by affecting glycerolipid metabolism, fatty acid degradation, circadian entrainment, circadian rhythm, and dopaminergic synapse.

Abstract
This study aimed to evaluate the functional and probiotic properties of Lactobacillus acidophilus SJLH001 (La-SJLH001) isolated from fermented food via mechanism analysis based on transcriptomics and culturomics. La-SJLH001 exhibited good tolerance to acid and bile salt conditions with anti-diabetic ability and cholesterol assimilation activity in vitro. Supplementation with La-SJLH001 also resulted in a significant reduction in host oral glucose and serum total cholesterol levels in vivo. Transcriptome profiles and qPCR analysis suggested that La-SJLH001 significantly regulated the transcription of key genes involved in glucose transportation, cholesterol metabolism, ion channels, and immune response, resulting in improved glucose homeostasis and cholesterol metabolism. La-SJLH001 significantly affected the structure of intestinal microbiota when analyzed by using culturomics coupled with MALDI-TOF MS. These results indicated that La-SJLH001 may be a mechanistic target for the control of diabetes with great potential in the application of probiotic products.
