Abstract Objectives: Cancer treatment relies heavily on accurate diagnosis and effective monitoring of the disease. These processes often involve invasive procedures, such as colonoscopy, to detect malignant tissues, followed by molecular analyses to determine relevant biomarkers. This study aimed to evaluate the clinical performance of droplet digital PCR (ddPCR) for detecting Kirsten Rat Sarcoma Viral Proto-Oncogene (KRAS), Neuroblastoma RAS Viral Oncogene Homolog (NRAS), and B-Raf Murine Sarcoma Viral Oncogene Homolog B (BRAF) mutations in circulating tumor DNA (ctDNA) from colorectal cancer patients using liquid biopsy. Methods: ctDNA was isolated from colorectal cancer (CRC) patients (n = 110) and analyzed for KRAS, BRAF,… More >

Abstract Colorectal cancer (CRC) is the third most common malignancy worldwide and the second leading cause of cancer-related deaths, accounting for approximately 10% of all cancer cases. By 2050, CRC incidence is expected to rise substantially, driven by population aging and greater exposure to risk factors in developing countries. Despite advances in medicine and pharmacy, the effectiveness of available treatments remains limited, underscoring the urgent need for innovative therapeutic strategies. This review summarizes and critically evaluates currently available CRC therapies and explores new emerging directions. Particular attention is given to the role of immunotherapy, targeted therapies,… More >

Abstract Objectives: The mechanism by which specific tumor subsets in colorectal cancer (CRC) use alternative metabolic pathways, particularly those modulated by hypoxia and fructose, to alter the tumor microenvironment (TME) remains unclear. This study aimed to identify these malignant subpopulations and characterize their intercellular signaling networks and spatial organization through an integrative multi-omics approach. Methods: Leveraging bulk datasets, single-cell RNA sequencing, and integrative spatial transcriptomics, we developed a prognostic model based on hypoxia-and fructose metabolism-related genes (HFGs) to delineate tumor cell subpopulations and their intercellular signaling networks. Results: We identified a specific subset of stanniocalcin-2 positive (STC2+)… More > Graphic Abstract

Abstract Background: Colorectal cancer (CRC) is common and deadly, often leading to metastasis, challenging treatment, and poor outcomes. Understanding its molecular basis is crucial for developing effective therapies. Aims: This study aimed to investigate the role of Myosin Heavy Chain 11 (MYH11) in CRC progression, especially its effects on epithelial-mesenchymal transition (EMT) and cell behavior, and to explore its potential regulation by the EMT transcription factor zinc finger E-box binding homeobox 1 (ZEB1). Methods: Differential expression analysis was performed in the GSE123390 and TCGA-READ datasets, and 317 intersection genes were identified. The hub gene MYH11 was identified… More >

Abstract Background: VPS37A (VPS37A subunit of ESCRT-I), a component of the ESCRT-I (endosomal sorting complex required for transport I) complex, mediates vesicular trafficking through sorting endocytic ubiquitinated cargos into multivesicular bodies (MVBs). Although accumulating evidence indicates that VPS37A deficiency occurs in numerous malignancies and exerts tumor-suppressive effects during cancer progression, its functional significance in colorectal cancer (CRC) pathogenesis remains poorly characterized. Therefore, this study aims to further investigate the functional and molecular mechanisms by which VPS37A downregulation contributes to malignant biological phenotypes in CRC, with a specific focus on how its dysregulation affects cell death pathways.… More > Graphic Abstract

Abstract Objectives: Colorectal cancer (CRC) is one of the most common cancers all over the world. The progression of CRC is associated with inflammation and disruptions in intestinal flora. 3-O-Acetyl-11-keto-β-boswellic acid (AKBA) has been noted for its potent anti-inflammatory properties. However, the effect of AKBA on colon cancer caused by inflammation and its mechanism are not unclear. The study is to explore the effect of AKBA on CRC and its mechanism. Materials and Methods: Cell proliferation, (5-ethynyl-2^′-deoxyuridine, EdU)-DNA synthesis assay and colony formation were used to assess the effect of AKBA on the proliferation of CRC cells.… More >

Abstract Background: Tumor angiogenesis is related to solid tumor occurrence. Ubiquitin-specific peptidase 13 (USP13) is a deubiquitinating enzyme with a pivotal effect on tumor proliferation, metastasis, and tumorigenesis. Nonetheless, its effect on colorectal cancer (CRC) angiogenesis remains poorly understood. Methods: Human umbilical vein endothelial cells (HUVECs) and CRC cells were cultivated, followed by USP13 knockdown/overexpression using shRNA lentiviral vectors or plasmids. Conditioned media (CM) from treated CRC cells were collected to assess HUVEC migration, invasion, and tube formation. Phosphatase and tensin homolog (PTEN) overexpression and recombinant vascular endothelial growth factor A (VEGFA) rescue experiments were performed.… More >

Abstract Lynch syndrome (LS), also known as hereditary non-polyposis colorectal cancer (HNPCC), is an inherited condition associated with a higher risk of colorectal cancer (CRC) and other cancers. It is caused by germline mutations in DNA mismatch repair (MMR) genes, including MLH1, MSH2, MSH6 and PMS2. These mutations lead to microsatellite instability (MSI) and defective DNA repair mechanisms, resulting in increased cancer risk. Early detection of LS is crucial for effective management and cancer prevention. Endoscopic surveillance, particularly regular colonoscopy, is recommended for individuals with LS to detect CRC at early stages. Additionally, universal screening of CRC for More > Graphic Abstract

Abstract Background: Colorectal cancer (CRC) holds the third position in global cancer prevalence mortality. Although chemotherapy is a conventional treatment, recent investigations have shed light on the therapeutic potential of the cGAS cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway in CRC management. Despite the primary role of the death domain-associated protein (Daxx) in cellular apoptosis, its influence on the regulation of cGAS-STING activation remains elusive. Methods: The Daxx degradation and speck formation were conducted using immunofluorescence and Western blotting. The Daxx knock-down and over-expression in CRC cells were performed to detect in vivo and in vitro… More >

Abstract Background: Chitosan oligosaccharide (COS) is the major degradation product of chitosan by enzymatic processes. COS, with complete water solubility, exerts significant biological effects, including anti-cancer activity. We investigated the anti-tumor effects of COS on colorectal cancer as effective therapeutic methods with low side effects are lacking. Methods: COS was obtained from low molecular weight chitosan by an enzymatic method and the anti-cancer effects were measured by cell viability assay, flow cytometry analysis, Western blotting, and xenograft. Results: COS suppressed the proliferation of SNU-C5 cells compared to other colorectal cancer cells, but higher concentrations were required in… More > Graphic Abstract
