摘要

Iron is an essential nutrient required for normal cellular functions, growth, and proliferation. Iron homeostasis is maintained at the cellular and systemic levels by strict regulation of genes involved in the process of iron uptake, storage, export, and surveillance of iron levels. Cellular iron homeostasis is dysregulated in cancer to sustain rapid growth and proliferation. Cellular iron levels are increased in cancer by manipulating the expression of genes involved in iron metabolism. Recent studies show that a class of small non-coding RNA known as microRNA (miRNA) play a major role in the control of iron metabolism. This review summarizes the significance of iron in cancer prognosis and how miRNAs regulate the expression of genes involved in iron metabolism to increase the cellular iron availability in cancer.
