Developmentally-related candidate retinoic acid target genes regulated early during neuronal differentiation of human embryonal carcinoma.

Embryonal carcinoma is a model of embryonic development as well as tumor cell differentiation. In response to all-trans retinoic acid (RA), the human embryonal carcinoma (EC) cell line, NT2/D1, differentiates toward a neuronal lineage with associated loss of cell growth and tumorigenicity. Through the use of cDNA-based microarrays we sought to identify the early downstream targets of RA during differentiation commitment of NT2/D1 cells.
