tokens: 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 .
