Treatment of the acute promyelocytic (APL) cell line NB4 with interferon alpha ( IFN(alpha) ), as well as IFN ( beta ) and gamma , results in an increased expression of the transcripts coding for retinoic-acid receptor type alpha ( RAR(alpha) ) and the leukemia-specific retinoic acid receptor PML-RAR .
 protein: retinoic-acid receptor type alpha; protein: leukemia-specific retinoic acid receptor; protein: interferon alpha; protein: RAR(alpha); protein: IFN(alpha); cell line: acute promyelocytic (APL) cell line; protein: PML-RAR; cell line: NB4
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2".
