Our data suggest that differentiation dependent increase of lysosomal acid lipase ( LAL ) expression in THP-1 cells is mediated by a concerted action of Sp1 and AP-2 .
 ( protein: LAL, None) , ( cell line: THP-1 cells, None) , ( protein: Sp1, None) , ( protein: AP-2, None) , ( protein: lysosomal acid lipase, None)
