Dysregulation of Iron Metabolism in Cancer Stem Cells.

Summary of "Dysregulation of Iron Metabolism in Cancer Stem Cells."

Cancer stem cells (CSCs) are a distinct subpopulation of tumor cells endowed with stem-like properties. Importantly, CSCs can survive current standard therapies, resulting in metastatic disease and tumor recurrence. Here we describe the alterations of iron homeostasis occurring in CSCs, which in general are characterized by high intracellular iron content. Importantly, abnormalities of iron metabolism correlate with faster tumor growth and adverse prognosis in cancer patients. In line with the dependence of cancer on iron, we also discuss iron-dependent mechanisms as druggable pathways, as iron chelators have been considered for tumor therapy and new molecules currently proposed and studied as antineoplastic drugs may impinge on iron and its capacity to promote oxidative stress to have therapeutic value in cancer.

Iron and Cancer.

This review explores the multifaceted role that iron has in cancer biology. Epidemiological studies have demonstrated an association between excess iron and increased cancer incidence and risk, while ...

A promising new approach to cancer therapy: Targeting iron metabolism in Cancer Stem Cells.

Iron is an essential nutrient that facilitates cell proliferation and growth. Iron can be detrimental, however. The ability of iron to cycle between oxidized and reduced forms contributes to the forma...

Regulation of cellular iron metabolism: Iron-dependent degradation of IRP by SCF ubiquitin ligase.

Because of essentiality and toxicity of iron in our body, iron metabolism is tightly regulated in cells. In mammalian cells, iron regulatory protein 1 and 2 (IRP1 and IRP2) are the central regulators ...

Iron levels, genes involved in iron metabolism and antioxidative processes and lung cancer incidence.

Lung cancer is the most common adult malignancy accounting for the largest proportion of cancer related deaths. Iron (Fe) is an essential trace element and is a component of several major metabolic pa...

TAp73 modifies metabolism and positively regulates growth of cancer stem-like cells in a redox-sensitive manner.

Stem-like cancer cells, with characteristic self-renewal abilities, remain highly refractory to various clinical interventions. As such, stemness-inhibiting entities, such as tumor suppressor p53, are...

Medical and Biotech [MESH] Definitions

A multifunctional iron-sulfur protein that is both an iron regulatory protein and cytoplasmic form of aconitate hydratase. It binds to iron regulatory elements found on mRNAs involved in iron metabolism and regulates their translation. Its rate of degradation is increased in the presence of IRON.

A multifunctional iron-sulfur protein that is both an iron regulatory protein and cytoplasmic form of aconitate hydratase. It binds to iron regulatory elements found on mRNAs involved in iron metabolism and regulates their translation. Its RNA binding ability and its aconitate hydrolase activity are dependent upon availability of IRON.

Specialized stem cells that are committed to give rise to cells that have a particular function; examples are MYOBLASTS; MYELOID PROGENITOR CELLS; and skin stem cells. (Stem Cells: A Primer [Internet]. Bethesda (MD): National Institutes of Health (US); 2000 May [cited 2002 Apr 5]. Available from: http://www.nih.gov/news/stemcell/primer.htm)

The reaction of potassium ferrocyanide with ferric iron to yield a dark blue precipitate at the sites of the ferric iron. Used to determine ferric iron in tissues, particularly in the diagnosis of disorders of iron metabolism.

Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
