Induction of MEL cell differentiation by enforced HERF1 expression. MEL cells expressing the tetracycline-regulated Tet-VP16 fusion protein, either with an empty plasmid vector (parental) or with a tetracycline-regulated HERF1-containing plasmid (clones 1 to 3), were grown in the presence (+) or absence (−) of tetracycline (tet). Following the indicated treatments, cells were isolated and analyzed by Northern blot analysis (A) and morphology (B). Northern blots were sequentially hybridized with probes specific for the genes listed on the right side.
