Colorectal cancer is one of the most prevalent and deadly cancers worldwide. MicroRNAs are short single stranded non-coding RNAs that play important roles in carcinogenesis, tumor growth and tumor survival. Circulating microRNAs are increasingly becoming efficient and important biomarkers for several types of cancers. Herein, we aim to evaluate the diagnostic potentials of plasma microRNA-211 and microRNA-25 in colorectal cancer patients. Forty-four patients diagnosed with colorectal cancer and 40 healthy controls were recruited for the present study. Expressions of circulating microRNAs -211 and 25 were assessed by quantitative real-time polymerase chain reaction (RT-qPCR). Expression of transforming growth factor-beta, a key factor in tumorigenesis and a key inducer of epithelial to mesenchymal transition was assessed by enzyme-linked immunosorbent assay (ELISA) in patients' tissue and plasma. Our results demonstrated upregulated expressions of plasma microRNAs-211 and 25 correlated with the high transforming growth factor-beta (TGF-β1) expression in patients. In addition, plasma levels were positively correlated with lymph node metastasis. Moreover, receiver operating characteristic analysis demonstrated the reliability of microRNAs-211 and 25 for discriminating colorectal cancer patients from healthy individuals. MicroRNA-211 and microRNA-25 might have a tumorigenic role in colorectal cancer and their plasma levels could be potential biomarkers in its diagnosis.

Probiotics exert a diverse range of immunomodulatory effects on the human gut immune system. These mechanisms encompass strengthening the intestinal mucosal barrier, inhibiting pathogen adhesion and colonization, stimulating immune modulation, and fostering the production of beneficial substances. As a result, probiotics hold significant potential in the prevention and treatment of various conditions, including inflammatory bowel disease and colorectal cancer.

Background: This study investigates the association of single nucleotide polymorphism in glutathione S transferase P1 (rs1695 and rs1138272) and phosphatase and TENsin homolog (rs701848 and rs2735343) with the risk of colorectal cancer (CRC).

Patients And Methods: In this case-control study, 250 healthy controls and 200 CRC patients were enrolled. All subjects were divided into 3 groups: healthy control, patients, and overall (control + patients).

Department of General Surgery (Colorectal Surgery), The Sixth Affiliated Hospital, Sun Yat-sen University, Guangzhou, Guangdong, China.

Background: Immunotherapy is beneficial for some colorectal cancer (CRC) patients, but immunosuppressive networks limit its effectiveness. Cancer-associatedfibroblasts (CAFs) are significant in immune escape and resistance toimmunotherapy, emphasizing the urgent need for new treatment strategies.

Methods: Flow cytometric, Western blotting, proteomics analysis, analysis of public database data, genetically modified cell line models, T cell coculture, crystal violetstaining, ELISA, metabonomic and clinical tumour samples were conducted to assess the role of EDEM3 in immune escape and itsmolecular mechanisms.
