The gut microbiota, a dynamic ecosystem of trillions microorganisms, produces secondary metabolites that profoundly influence host health. Recent research has highlighted the significant role these metabolites, particularly short-chain fatty acids, indoles, and bile in modulating immune responses, impacting epigenetic mechanisms, contributing to disease processes. In gastrointestinal (GI) cancers such as colorectal, liver, gastric cancer, microbial can drive tumorigenesis by promoting inflammation, DNA damage, evasion. Conversely, same hold therapeutic promise, potentially enhancing responses chemotherapy immunotherapy even directly suppressing tumor growth. addition, play crucial roles infectious susceptibility resilience, mediating pathways impact pathogen resistance. By consolidating recent insights into microbiota's shaping health, this review underscores potential targeting microbiome-derived for treating GI diseases calls further microbiome-based interventions.

Abstract The causal relationship between gut microbiota (GM) and pancreatic cancer (PC) remains unclear. This study aimed to investigate the potential genes underlying this mechanism. GM Genome‐wide association (GWAS) summary data were from MiBioGen consortium. PC GWAS National Human Genome Research Institute‐European Bioinformatics Institute (NHGRI‐EBI) Catalogue. To detect PC, we implemented three complementary Mendelian randomization (MR) methods: Inverse Variance Weighting (IVW), MR‐Egger Weighted Median, followed by sensitivity analyses. Furthermore, integrated with blood cis‐expression quantitative trait loci (eQTLs) cis‐DNA methylation QTL (mQTLs) using Summary data‐based Randomization (SMR) methods. integration prioritize GM‐affecting through SMR analysis of two molecular traits. cis‐eQTLs cis‐mQTLs summarized Cancer Atlas (TCGA) data. Through colocalization cis‐QTLs data, identified common that influence both PC. Our found a including four protective five risk‐associated [Inverse p < 0.05].

Colorectal cancer (CRC) is one of the most common malignant tumors primarily affecting individuals over age 50 years. Recent studies have suggested that dysbiosis gut microbiota, a community microorganisms in human gut, closely associated with occurrence and development CRC. Additionally, inflammatory factors (IFs) also been reported to play significant role However, causal relationships between IFs, CRC remain unclear. In this study, we performed Mendelian randomization (MR) analysis using publicly available genome-wide association study (GWAS) data explore relationship The microbiota GWAS were obtained from MiBioGen while IFs derived comprehensive three independent cohorts. Causal was conducted appropriate instrumental variables (IVs) statistical models. MR revealed negative correlation Lachnospiraceae species risk, positive observed Porphyromonadaceae species, UCG010 genus, Lachnospira Sellimonas genus risk. IL-10 These findings suggest might be an increased risk specific bacterial groups may crucial Using analysis, as well CRC, provide important clues for potential roles regulation factor control prevention treatment

Abstract Background Colorectal cancer (CRC) is the third most prevalent malignant tumor and second leading cause of cancer-related deaths globally. The genus Parabacteroides an important component gut microbiota. P. distasonis goldsteinii are reported probiotics, their roles in CRC have been investigated related studies. However, association between johnsonii remains unknown. Methods (10–42) Lactococcus formosensis (22–2) were isolated from healthy human feces. 25 mice that demonstrated normal feeding activity randomly assigned to four groups : control (NC group), model (IC (PJ L. (LO group). Colonic tissues IC, PJ, LO colon NC group then collected for HE staining immunohistochemical staining. Fecal samples during hyperproliferative adenoma phases Metagenomic sequencing metabolite analysis. Results intervention reduced number slowed growth colonic tumors, improved histological scores, decreased microenvironmental inflammation levels. composition intestinal flora with cancer, increased microbial species diversity, maintained microbiota stability. Furthermore, abundance Bifidobacterium pseudolongum Lactobacillus, which play a role ameliorating AOM/DSS-induced dysbiosis. affected metabolic pathways, including amino sugar degradation galactose metabolism, sphingolipid synthesis, acid polyphenol synthesis tryptophan metabolism pathway as primary being affected. Conclusion Our study profiled administration reduces tumors lower staging by modulating its metabolites at early stages.
