One-Carbon Metabolism: Biological Players in Epithelial Ovarian Cancer

International Journal of Molecular Sciences
Andrea RizzoDelia Mezzanzanica

Abstract

Metabolism is deeply involved in cell behavior and homeostasis maintenance, with metabolites acting as molecular intermediates to modulate cellular functions. In particular, one-carbon metabolism is a key biochemical pathway necessary to provide carbon units required for critical processes, including nucleotide biosynthesis, epigenetic methylation, and cell redox-status regulation. It is, therefore, not surprising that alterations in this pathway may acquire fundamental importance in cancer onset and progression. Two of the major actors in one-carbon metabolism, folate and choline, play a key role in the pathobiology of epithelial ovarian cancer (EOC), the deadliest gynecological malignancy. EOC is characterized by a cholinic phenotype sustained via increased activity of choline kinase alpha, and via membrane overexpression of the alpha isoform of the folate receptor (FRα), both of which are known to contribute to generating regulatory signals that support EOC cell aggressiveness and proliferation. Here, we describe in detail the main biological processes associated with one-carbon metabolism, and the current knowledge about its role in EOC. Moreover, since the cholinic phenotype and FRα overexpression are unique properties of ...Continue Reading

Cancer Epigenetics & Metabolism (Keystone)

Epigenetic changes are present and dysregulated in many cancers, including DNA methylation, non-coding RNA segments and post-translational protein modifications. The epigenetic changes may or may not provide advantages for the cancer cells. This feed focuses on the relationship between cell metabolism, epigenetics and tumor differentiation.

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.
