Taken together these data indicate that carboxylesterase gene transcription in THP-1 cells starts at multiple initiation sites and that Sp1 and IRBP may be critical factors for modulating the differentiation-dependent transcription of this human carboxylesterase gene .
 ( DNA: human carboxylesterase gene, None) , ( protein: Sp1, None) , ( cell line: THP-1 cells, None) , ( protein: human carboxylesterase, None) , ( protein: IRBP, None)
