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 .
 CTLL-2, T cells, oncostatin M, IL-4, CIS, IL-4, cytokine-inducible SH2-containing protein, STAT5, beta-casein, STAT5, OSM, STAT5, STAT5 -regulated genes
