Folate metabolism in myelofibrosis: a missing key?
Folates serve as key enzyme cofactors in several biological processes. Folic acid supplementation is a cornerstone practice but may have a “dark side”. Indeed, the accumulation of circulating unmetabolized folic acid (UMFA) has been associated with various chronic inflammatory conditions, including cancer. Additionally, by engaging specific folate receptors, folates can directly stimulate cancer cells and modulate the expression of genes coding for pro-inflammatory and pro-fibrotic cytokines.
This evidence could be extremely relevant for myelofibrosis (MF), a chronic myeloproliferative neoplasm typified by the unique combination of clonal proliferation, chronic inflammation, and progressive bone marrow fibrosis. Folate supplementation is frequently associated with conventional or investigational drugs in the treatment of MF-related anemia to tackle ineffective erythropoiesis. In this review, we cover the different aspects of folate metabolism entailed in the behavior and function of normal and malignant hematopoietic cells and discuss the potential implications on the biology of myelofibrosis.
期刊介绍：
Annals of Hematology covers the whole spectrum of clinical and experimental hematology, hemostaseology, blood transfusion, and related aspects of medical oncology, including diagnosis and treatment of leukemias, lymphatic neoplasias and solid tumors, and transplantation of hematopoietic stem cells. Coverage includes general aspects of oncology, molecular biology and immunology as pertinent to problems of human blood disease. The journal is associated with the German Society for Hematology and Medical Oncology, and the Austrian Society for Hematology and Oncology.
