Evaluation of CD34+ - and Lin- -selected cells from peripheral blood stem cell grafts of patients with lymphoma during differentiation in culture ex vivo using a cDNA microarray technique.

abstract：:Activation of the N-ras gene via coding region mutations has been previously documented in 25% of patients with acute myeloid leukemia (AML). Since overexpression of normal N-ras is also transforming in vitro, the N-ras promoter of AML patients was analyzed for the presence of promoter mutations that may affect expres...

abstract：:A functional method for estimation of plasminogen activator (PA) activity is described. The end-point method follows the PA-dependent conversion of the inactive plasminogen to the potent protease plasmin. The formation of plasmin is monitored by its activity on 14C-globin to form acid-soluble radioactive products. The...
