All NK clones and cell lines studied were found to express hGATA-3-specific mRNA , suggesting that hGATA-3 may be involved in the regulation of the unrearranged TcR delta gene expression in NK cells .
 ( DNA: TcR delta gene, None) , ( RNA: hGATA-3-specific mRNA, None) , ( cell type: NK cells, None) , ( protein: hGATA-3, None) , ( cell line: NK clones, None)
