Our results implicate NFIL3/E4BP4 ( nuclear factor regulated by IL-3 /adenovirus E4 promoter binding protein ) in a distinct growth factor-regulated signaling pathway that is responsible for the survival of early B-cell progenitors , and whose alteration by E2A-HLF leads to childhood B lineage leukemia .
 ( protein: E2A-HLF, None) , ( protein: nuclear factor regulated by IL-3 /adenovirus E4 promoter binding protein, None) , ( cell type: early B-cell progenitors, None) , ( protein: IL-3, None) , ( protein: NFIL3/E4BP4, None)
