While IL-4 does not activate STAT5 , it induces expression of STAT5 -regulated genes in CTLL-2 , i.e. beta-casein , a cytokine-inducible SH2-containing protein ( CIS ), and oncostatin M ( OSM ), suggesting that STAT6 activated by IL-4 substitutes for the function of STAT5 in T cells .
 cell line: CTLL-2; cell type: T cells; protein: oncostatin M; protein: IL-4; protein: CIS; protein: IL-4; protein: cytokine-inducible SH2-containing protein; protein: STAT5; protein: beta-casein; protein: STAT5; protein: OSM; protein: STAT5; DNA: STAT5 -regulated genes
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2". 
Option: cell line, protein, RNA, DNA, cell type
