Approximately 25% of colorectal cancer (CRC) patients will develop metastatic (m)CRC despite treatment interventions. In this setting, tumor cells are attracted to the epidermal growth factor receptor () oncogene. Kirsten rat sarcoma (RAS) 2 viral oncogene homolog () mutations were reported to drive CRC by promoting cancer progression in activating Wnt/β-catenin and RAS/extracellular signal-regulated kinase (ERK) pathways.

Gamma-mangostin isolated from garcinia mangostana suppresses colon carcinogenesis and stemness by downregulating the GSK3β/β-catenin/CDK6 cancer stem pathway.

Background: Despite advances in chemotherapies and targeted drugs, colorectal cancer (CRC) remains challenging to treat due to drug resistance. Emerging evidence indicates that cancer-associated fibroblasts (CAFs) facilitate the generation of cancer stem-like cells (CSCs) and drug resistance. Glycogen synthase kinase-3 (GSK) associated signaling pathways have been implicated in the generation of CSCs and represent a target for therapeutics development.

Comprehensive Omics Analysis of a Novel Small-Molecule Inhibitor of Chemoresistant Oncogenic Signatures in Colorectal Cancer Cell with Antitumor Effects.

Tumor recurrence from cancer stem cells (CSCs) and metastasis often occur post-treatment in colorectal cancer (CRC), leading to chemoresistance and resistance to targeted therapy. is a transcription factor in the nuclei that modulates cell growth and development, and regulates immune response in an antitumor direction by mediating programmed death ligand 1 () and promoting CRC tumor recurrence after adjuvant chemotherapy. However, the molecular mechanism through which maintains stemness and confers treatment resistance still remains elusive in CRC.

Preclinical investigation of ovatodiolide as a potential inhibitor of colon cancer stem cells via downregulating sphere-derived exosomal β-catenin/STAT3/miR-1246 cargoes.

Patients with advanced-stage colon cancer often exhibit resistance against treatment and distant metastasis, both key contributors to poor prognosis. Emerging evidence indicates that cancer stem cells (CSCs), characterized by the enhanced ability to self-renew, resist therapeutics, and promote metastasis, represents a clinical challenge to target. Alternative therapeutic approaches are urgently required.

Preclinical Evaluation of the Novel Small-Molecule MSI-N1014 for Treating Drug-Resistant Colon Cancer via the LGR5/β-catenin/miR-142-3p Network and Reducing Cancer-Associated Fibroblast Transformation.

Colorectal cancer represents one of the most prevalent malignancies globally, with an estimated 140,000 new cases in the United States alone in 2019. Despite advancements in interventions, drug resistance occurs in virtually all patients diagnosed with late stages of colon cancer. Amplified epidermal growth factor receptor (EGFR) signaling is one of the most prevalent oncogenic drivers in patients and induces increased Janus kinase (JAK)/signal transduction and activator of transcription (STAT) and β-catenin functions, all of which facilitate disease progression.
