Tra2alpha promotes RA induced neural differentiation of P19 cells.
The present study demonstrates a high level of the nuclear Transformer 2alpha (Tra2alpha) protein in adult mouse brain relative to other tissues, including muscle, heart, liver, lungs, kidney and small intestine, suggesting the potential importance of Tra2alpha in neural function. The level of Tra2alpha in mouse cerebrum is developmentally regulated, peaking at neonate stage. In P19 carcinoma cells, Tra2alpha is transiently up-regulated upon retinoic acid (RA) treatment. Although over-expression of Tra2alpha protein alone does not elicit P19 differentiation, under these conditions the response of P19 cells to RA is significantly increased. The results suggest that Tra2alpha proteins may act as a mediator in the signal pathway associated with RA-induced differentiation in P19 cells.
