MiRNAs are small noncoding RNA molecules that are often aberrantly over- or underexpressed in tumors, including colorectal cancer (CRC). Due to their capacity to regulate and thus fine-tune the expression of multiple target genes relevant in tumorigenesis,tumor progression, angiogenesis, metastasis and sensitivity towards chemotherapy, they influence various pivotal cellular processes with prognostic and therapeutic relevance in CRC.This review provides a comprehensive overview of miRNAs with established functional relevance in colorectal cancer, their established target genes and the resulting cellular and pathological phenotype(s). Furthermore, approaches towards therapeutic miRNA-based intervention are discussed. Those include viral or non-viral approaches of miRNA replacement therapy in the case of tumor-suppressing miRNAs, and multiple strategies for the inhibition of oncogenic miRNAs. Beyond the analysis of the functional relevance of a given miRNA as target molecule or a miRNA-based drug, several studies in preclinical in vivo models are described that provide the basis for possible future therapeutic intervention in man.

Objective: The clinical benefits of neoadjuvant bevacizumab plus chemotherapy in locally advanced gastric cancer patients are controversial. This study intended to evaluate the efficacy and safety of neoadjuvant bevacizumab plus chemotherapy in these patients.
Methods: In this retrospective study, 71 locally advanced gastric cancer patients receiving neoadjuvant bevacizumab plus chemotherapy or neoadjuvant chemotherapy alone were divided into bevacizumab plus chemo group (N = 23) and chemo group (N = 48).

Background: DNA hypomethylation and uracil misincorporation into DNA, both of which have a very important correlation with colorectal carcinogenesis. Folate plays a crucial role in DNA synthesis, acting as a coenzyme in one-carbon metabolism, which involves the synthesis of purines, pyrimidines, and methyl groups. MTHFR, a key enzyme in folate metabolism, has been widely studied in relation to neural tube defects and hypertension, but its role in colorectal cancer remains underexplored.

Background: Early detection and diagnosis of cancer are vital to improving outcomes for patients. Artificial intelligence (AI) models have shown promise in the early detection and diagnosis of cancer, but there is limited evidence on methods that fully exploit the longitudinal data stored within electronic health records (EHRs). This review aims to summarise methods currently utilised for prediction of cancer from longitudinal data and provides recommendations on how such models should be developed.

Objectives: To address the issue that most microsatellite-stable (MSS) and proficient mismatch repair (pMMR) metastatic colorectal cancer (mCRC) patients have minimal response to immunotherapy, this meta-analysis evaluated the efficacy and safety of durvalumab and tremelimumab with concomitant treatment in treating MSS/pMMR metastatic colorectal cancer.
Methods: All included trials were prospective studies with a median patient age of 63 years, of which 94.2% were MSS/pMMR mCRC patients, with a male to female ratio of 1.

Hyperactivation of the YAP/TEAD transcriptional complex in cancers facilitates the development of an immunosuppressive tumor microenvironment. Herein, we observed that the transcription factor SP1 physically interacts with and stabilizes the YAP/TEAD complex at regulatory genomic loci in colorectal cancer (CRC). In response to serum stimulation, PKCζ (protein kinase C ζ) was found to phosphorylate SP1 and enhance its interaction with TEAD4.
