The winged-helix transcription factor Trident is expressed in cycling cells

Abstract

We describe the cloning and characterization of Trident , a novel member of the fork head/winged-helix family, from murine thymus. In the mouse embryo, the gene was expressed in all tissues, whereas in adult mice expression was only detected in the thymus. Further analysis revealed that Trident expression strictly correlated with cell cycling, independent of cell type. Timing of [3H]thymidine incorporation showed that mRNA and protein expression were strongly upregulated upon entry into the S phase of the cell…
