Colorectal cancer stem cell: a potential therapeutic target.
Summary of "Colorectal cancer stem cell: a potential therapeutic target."
The discovery of cancer stem cells has improved our understanding of tumour occurrence and development. Colorectal cancer stem cells may be derived from mutations in normal intestinal epithelial stem cells. CD133+ and aldehyde dehydrogenase 1 (ALDH1)+ cells have strong tumorigenic capacities and may represent different subpopulations of colorectal cancer stem cells. Multiple signalling pathways, especially the Wnt pathway, are important in colorectal cancer occurrence and development, and maintaining the stemness of colorectal cancer stem cells. Identifying colorectal cancer stem cells and understanding the related signalling pathways are important for developing new targeted interventions for colorectal cancer.

Medical and Biotech [MESH] Definitions
Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).
Aberrant Crypt Foci
Clusters of colonic crypts that appear different from the surrounding mucosa when visualized after staining. They are of interest as putative precursors to colorectal adenomas and potential biomarkers for colorectal carcinoma.
Colorectal Neoplasms, Hereditary Nonpolyposis
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
INTRODUCTION: Despite the various therapeutic combinations and the emergence of new targeted therapies, there is still no curative treatment for all stages of colorectal cancer. Through the query for...
While cancer treatment modalities are gradually improving due to increased knowledge about tumor heterogeneity and the cancer stem cell hypothesis, there remains a disconnect between tumor detection a...
Over 50% of patients with colorectal cancer (CRC) will progress and/or develop metastases. Biomarkers capable of predicting progression, risk stratification and therapeutic benefit are needed. Cancer...
Normal tissue homeostasis involves a careful balance between the normal cell loss and renewal. Stem and progenitor cells help maintain this precise and fine balance through their ability of self-renew...
AIM: In this study, we present our patients with metachronous colorectal cancer. PATIENTS AND METHODS: In the period between 1990 and 2009, 670 patients with colorectal cancer were treated. RESULTS: M...
The addition of RAD001, an mTOR inhibitor, to irinotecan and anti-EGFR antibody cetuximab may increase efficacy for patients with metastatic colorectal cancer who progressed on prior chemo...
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. Peripheral...
The study induces an immune response towards the stem-cell like part of glioblastomas in combination with standard therapy. The aim is to define and characterize the feasibility, potential...
This observational study will assess the treatment duration, progression-free survival, reason for stopping treatment and patient and tumor characteristics of bevacizumab [Avastin] treatme...
Rationale: Studying samples of blood from HIV-positive patients with cancer in the laboratory may help doctors learn more about changes that occur in the immune system after stem cell tran...
