Differential expression of SOCS-2 in human leukemic cell lines.
(A,B) Northern blot of human leukemic cell lines exposed (+) or not (−) to 1 μM STI571 for 3 to 24 hours. Numbers below the blots represent the densitometric analysis of SOCS-2 levels, expressed as the ratio SOCS-2/β-actin before (−) and after (+) exposure to STI571.
