The sense cell lines ( U alpha S and its clonal derivative alpha G2S ) showed increased sensitivity to RA , while the antisense cell lines ( U alpha A and its clonal derivative alpha B5A ) showed decreased sensitivity to RA , as demonstrated by growth inhibition and by regulation of an RA -responsive reporter gene .
 cell line: U alpha A; cell line: U alpha S; cell line: B5A; cell line: antisense cell lines; cell line: G2S; cell line: sense cell lines; DNA: RA -responsive reporter gene
