Ketohexokinase-A acts as a nuclear protein kinase that mediates fructose-induced metastasis in breast cancer

Abstract

Apart from the enzymatic role of ketohexokinase isoform A (KHK-A) in fructose metabolism the alternative physiological functions of the enzyme are unclear. Here, the authors show that KHK-A mediates fructose-induced metastasis in breast cancer through a nuclear role in repressing the transcriptional activity of the cell-adhesion molecule CDH1.
