– The glia maturation factor gamma (GMFG) is a cytokine-responsive protein in erythropoietin-induced and granulocyte-colony stimulating factor-induced hematopoietic lineage development. It may mediate the pluripotentiality and lineage commitment of human hematopoietic stem cells. GMFG expression independently predicts poorer prognosis in patients with EOC. Ectopic overexpression of GMFG contributes to the malignant biological behavior of ovarian cancer cells.
