Colorectal cancer (CRC) is a common malignancy requiring early screening to improve patient outcomes. Current methods such as colonoscopy and fecal occult blood tests have several limitations including high cost, poor specificity, invasiveness, inconvenience. Recent research has identified specific bacterial communities associated with CRC, notably Parvimonas micra (P. micra), which serves biomarker for diagnosis owing its accumulation in the malignant tissues feces of CRC patients. Herein, we employed whole-bacterium systematic evolution ligands by exponential enrichment (SELEX) method isolate high-affinity aptamers against P. using 17 selection cycles. These were subsequently bound Au@Fe3O4 nanoparticles, interaction inhibited peroxidase-like activity thereby blocking 3,3',5,5'-tetramethylbenzidine (TMB) chromogenic reaction resulting measurable reduction absorbance. This colorimetric detection strategy demonstrated linear response across range 100-108 CFU/mL limit 11 CFU/mL. Using aptasensor, assessed abundance clinical samples found significantly higher levels patients compared that healthy individuals, was consistent quantitative polymerase chain results. study therefore represents first successful identification an aptamer affinity specificity micra, leading development highly sensitive aptasensor detection. The presented approach significant potential diagnosis.

Over the last two decades, molecular biology advances have revealed gut microbiota's active and crucial role in colorectal cancer (CRC) pathogenesis its dysregulation during tumorigenesis. This understanding has underscored urgency of exploring novel therapeutic approaches to address challenges posed by CRC. Among these approaches, nanosynergistic therapies, with their potential modulate microbiota, increase drug bioavailability stability, reduce side effects, emerged as a promising avenue. Furthermore, efficacy nanotechnology-based can be enhanced combining them different methods, including chemotherapy, radiotherapy, immunotherapy, photothermal therapy, sonodynamic therapy. Herein, recent progress nano synergistic therapy been reviewed, focusing on synergy between microbiota nanotechnology CRC treatment. Additionally, diverse applications nanoparticles analyzed provide innovative ideas effective solutions for developing highly treatment strategies.

ABSTRACT The incidence of colorectal cancer (CRC) has been increasing in recent decades. Current methods for CRC screening have their own drawbacks, thus there is an urgent need to identify the key microbes that drive development wider application early detection and prevention CRC. To address this issue, we performed fecal microbiome analysis by high-throughput sequencing 16S rRNA gene combined with blood biochemical indicators patients stages I, II, III, IV, healthy people, polyps. Fecal microbiota was disturbed, as evidenced significantly reduced α-diversity stage IV markedly different β-diversity. random forest model identified top 25 genera from 174 training data, resulting a diagnostic accuracy 87.95%. Further, combining differential analysis, screened out 11 biomarkers changed groups.

Summary Background Colorectal cancer (CRC) results from the accumulation of mutations and epigenetic changes in gut epithelial cells likely due to microbiota dysbiosis. However, limited research has been done explore link between host tumour dysbiosis disease outcome. Methods The mechanisms influencing outcomes 97 colorectal patients, including 13 with Lynch syndrome, 20 inflammatory bowel (IBD), 64 sporadic cases, were analyzed using a multiomics approach. These patients categorized into two groups: “disease-free/stable disease” “progression survival outcomes. analysis included tumor adherent composition (16S rRNA), somatic gene (WES), expression (RNAseq), immune markers (RNAscope), infiltrate (immunohistochemistry). Results IBD-CRC had worse than those or CRC, regardless TNM staging treatment. Symbiotic bacteria like Lactococcus lactis significantly reduced tissues. Patient influenced by abundance virulent ( Escherichia coli ) relative beneficial ). Although no significant increase deleterious was found IBD-CRC. 16sRNA revealed increased virulent- decreased anti-inflammatory symbiotic-bacteria correlating upregulation oncogenes downregulation anti-oncogenes PHLPP1. multiplex situ hybridization CD8, IFNγ PHLPP1 an anti-oncogene decrease detectable tissues as compared CRCs. Conclusion poor are cell alterations, possibly triggered microbiota-related pathways.
