The polysaccharides from seeds of Glycyrrhiza uralensis ameliorate metabolic disorders and restructure gut microbiota in type 2 diabetic mice
This study aims to investigate the effects of GUP on glucose and lipid metabolism as well as the intestinal microbiota in HFD/STZ-induced T2D. The results demonstrated that GUP could significantly ameliorate hyperglycemia, insulin resistance, oxidative stress, and reduce liver lipid levels in T2D mice. Furthermore, it also enhanced the integrity of the intestinal barrier in T2D mice by reducing the levels of pro-inflammatory cytokines and serum LPS levels. Interestingly, GUP treatment significantly lowered serum creatinine and urea nitrogen levels, mitigating renal function deterioration and interstitial fibrosis. Addition...

Urbanization influences the indoor transfer of airborne antibiotic resistance genes, which has a seasonally dependent pattern
Environ Int. 2024 Mar 1;185:108545. doi: 10.1016/j.envint.2024.108545. Online ahead of print.ABSTRACTOver the last few years, the cumulative use of antibiotics in healthcare institutions, as well as the rearing of livestock and poultry, has resulted in the accumulation of antibiotic resistance genes (ARGs). This presents a substantial danger to human health worldwide. The characteristics of airborne ARGs, especially those transferred from outdoors to indoors, remains largely unexplored in neighborhoods, even though a majority of human population spends most of their time there. We investigated airborne ARGs and mobile gene...

Factors Underlying the Difference in Response to Fecal Microbiota Transplantation Between IBS Patients with Severe and Moderate Symptoms
ConclusionsThere was no difference in the response to FMT between severe and moderate IBS when a 90-g transplant was administered to the small intestine. The difference in the bacterial profile between severe and moderate IBS may explain the difference in symptoms between these patients. (www.clinicaltrials.gov: NCT04236843).

The critical role of toll-like receptor 4 in bone remodeling of osteoporosis: from inflammation recognition to immunity
Osteoporosis is a common chronic metabolic bone disorder. Recently, increasing numbers of studies have demonstrated that Toll-like receptor 4 (TLR4, a receptor located on the surface of osteoclasts and osteoblasts) plays a pivotal role in the development of osteoporosis. Herein, we performed a comprehensive review to summarize the findings from the relevant studies within this topic. Clinical data showed that TLR4 polymorphisms and aberrant TLR4 expression have been associated with the clinical significance of osteoporosis. Mechanistically, dysregulation of osteoblasts and osteoclasts induced by abnormal expression of TLR4...

Microbiota enterotoxigenic Bacteroides fragilis-secreted BFT-1 promotes breast cancer cell stemness and chemoresistance through its functional receptor NOD1
Protein Cell. 2024 Mar 4:pwae005. doi: 10.1093/procel/pwae005. Online ahead of print.ABSTRACTTumor-resident microbiota in breast cancer promote cancer initiation and malignant progression. However, targeting microbiota to improve the effects of breast cancer therapy has not been investigated in detail. Here, we evaluated the microbiota composition of breast tumors and found that enterotoxigenic Bacteroides fragilis (ETBF) was highly enriched in the tumors of patients who did not respond to taxane-based neoadjuvant chemotherapy. ETBF, albeit at low biomass, secreted the toxic protein BFT-1 to promote breast cancer cell stem...

Dysfunction of cecal microbiota and CutC activity in mice mediating diarrhea with kidney-yang deficiency syndrome
ConclusionDiarrhea with kidney-yang deficiency syndrome significantly affects the physiological status, digestive enzyme activity, CutC activity, TMAO levels, and inflammatory response in mice. Additionally, there are changes in the composition and function of cecal microbiota, indicating an important impact of diarrhea with kidney-yang deficiency syndrome on the host intestinal microbiota balance. The occurrence of diarrhea with kidney-yang deficiency syndrome may be associated with dysbiosis of intestinal microbiota, increased CutC activity, elevated TMAO levels, and heightened inflammatory factor levels.

Effects of Chronic Unpredictable Mild Stress on Gut Microbiota and Fecal Amino Acid and Short-Chain Fatty Acid Pathways in Mice
In this study, we used 16S rDNA to examine changes in gut microbiota and predict related pathways in depression-like mice. Additionally, we employed liquid chromatography-mass spectrometry (LC-MS) to identify changes in amino acids and gas chromatography-mass spectrometry (GC-MS) to identify changes in short-chain fatty acids (SCFAs) in fecal samples. We conducted Pearson/Spearman correlation analysis to investigate the associations between changes in amino acids/SCFAs and behavioral outcomes. The 16S rDNA sequencing revealed significant alterations in gut microbiota at the phylum and genus levels in mice subjected to chro...

Clinical evidence of the link between gut microbiome and myalgic encephalomyelitis/chronic fatigue syndrome: a retrospective review
AbstractMyalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a heterogeneous disorder with elusive causes, but most likely because of clinical and other biological factors. As a vital environmental factor, the gut microbiome is increasingly emphasized in various refractory diseases including ME/CFS. The present study is aimed to enhance our understanding of the relationship between the gut microbiome and ME/CFS through data analysis of various clinical studies. We conducted a literature search in four databases (PubMed, Cochrane Library, Web of Science, and Google Scholar) until May 31, 2023. Our analysis encompa...

Alterations in gut microbiome associated with severity of atopic dermatitis in infants
CONCLUSION: Discrepancies in gut microbial composition and functional pathways were observed in infants with mild-to-severe AD. Alterations in butyrate-producing bacteria (Clostridium sensu stricto), sphingolipid-producing bacteria (Parabacteroides, Bacteroides), and related functional pathways were associated with the severity of AD infants.PMID:38419203 | DOI:10.1111/ajd.14237 (Source: The Australasian Journal of Dermatology)
