Using a subtraction method, we have isolated genes that are induced early in the differentiation of mouse 3T3-L1 preadipocyte cells into adipocytes. These include the genes encoding transcription factors and signalling proteins, as well as unknown genes. Bach1, a transcription factor, and ARA70, a cofactor, were rapidly induced during differentiation. The induction of these two genes was observed only in growth-arrested 3T3-L1 cells, and not in proliferating cells. In NIH-3T3 cells, no induction was observed under either set of conditions. These results strongly indicate that Bach1 and ARA70 have valuable roles at the onset of adipocyte differentiation.
