Objective Chronic hypercortisolism leads to a phenotype resembling metabolic syndrome. We aimed investigate the association between gut microbiota and abnormalities in endogenous (Cushing’s syndrome). Methods A total of 23 patients with Cushing’s syndrome (18 female 5 men, aged 47.24 ± 12.99 years) 30 age-, sex-and BMI-matched healthy controls 12 45.03 6.69 were consecutively recruited. Differences plasma short-chain fatty acid (SCFAs) concentrations analyzed by 16S rRNA sequencing gas chromatography-mass spectrometry (GC-MS). Results Compared controls, Simpson Pielou indices α diversity dramatically decreased ( P < 0.05). The community structure differed significantly controls. bacterial communities enriched Proteobacteria Escherichia-Shigella , depleted Firmicutes including Agathobacter Blautia Anaerostipes Eubacterium_eligens_group Lachnospira . Spearman analysis demonstrated that HbA1c, SBP, DBP, cortisol levels positively correlated whereas negatively Agathobacter, Blautia, Anaerostipes, Eubacterium_hallii_group, etc. also had lower propionic concentration (0.151±0.054 vs. 0.205±0.032 µg/mL, =0.039) than Furthermore, level was systolic pressure <0.05).

Abstract Background Gut microbiome is a community of microorganisms that lives in the human intestine and exerts various functions on host, including metabolic, immunoregulatory, control over cell proliferation. alterations have been associated with pathological conditions, such as diabetes mellitus, obesity, cardiovascular diseases.

ABSTRACT Microorganisms are a crucial component of lake ecosystems and significant contributors to biogeochemical cycles. However, the understanding how primary microorganism groups (e.g., bacteria fungi) distributed constructed within different habitats is lacking. We investigated bacterial fungal communities Hulun Lake using high-throughput sequencing techniques targeting 16S rRNA Internal Transcribed Spacer 2 genes, including range ecological statistical methodologies. Our findings reveal that environmental factors have high spatial temporal variability. The composition community structures vary significantly depending on differences in habitats. Variance partitioning analysis showed geographical accounted for <20% variation. Canonical correlation among factors, temperature, pH, dissolved oxygen had strong control over microbial communities. (bacterial fungal) were primarily controlled by dispersal limitations stochastic processes. This study offers fresh perspectives regarding maintenance mechanism biodiversity ecosystems, especially responses under identical stress. IMPORTANCE an important part freshwater ecosystem. microorganisms play role material circulation energy flow owing their unique enzymatic metabolic capacity. In this study, we observed varied widely water sediments Lake. factor affecting formation was identified as limitation during Environmental variation communities, with being factors. provide new insights into fungi environment, shed light processes building, deepen our ecosystems. results reference management conservation, particularly respect monitoring response changes.

Several studies have indicated that the gut microbiome and tumor microbiota may affect tumors. Emerging metabolomics research illustrates need to examine variations in microbial metabolite composition between patients with cancer healthy individuals. Microbial metabolites can impact progression of tumors immune response by influencing a number mechanisms, including modulation system, or immune‑related signaling pathways, epigenetic modification proteins DNA damage. also alleviate side effects drug resistance during chemotherapy immunotherapy, while effectively activating system exert immunotherapy. Nevertheless, on immunity be both beneficial harmful, potentially influenced concentration specific type. The present review summarizes roles various different solid tumors, alongside their influence treatment. Additionally, clinical trials evaluating therapeutic related microbes been listed. In summary, studying metabolites, which play crucial role interaction could lead identification new supplementary treatments for cancer. This has potential improve effectiveness treatment enhance patient prognosis.

Cancer remains a leading cause of global mortality. The tumor microbiota has increasingly been recognized as key regulator cancer onset and progression, in addition to shaping responses immunotherapy. Microbes, including viruses, bacteria, fungi, other eukaryotic species can impact the internal homeostasis health humans. Research focused on gut microflora intratumoral microbiome revolutionized current understanding how tumors grow, progress, resist therapeutic interventions. Even with this research, however, there relatively little that is known respect abundance microbes their effects microenvironment. Engineered exosomes are class artificial extracellular nanovesicles actively transport small molecule drugs nucleic acids, which have broad prospects cell therapy. present review offers an overview recent progress challenges associated engineered context research. These discussions used inform construction novel framework for exosome-mediated targeted drug delivery, taking advantage diversity strategic asset thereby providing new opportunities more effectively treat manage clinic.
