Expression of the AZU1-PRTN3-ELA2-ADN cluster of genes in cell lines studied. Northern analysis was performed on U-937 cells, U-937 cells treated with 25 ng/mL TPA for 3 days (TPA), COLO 201 (COLO), HUT 78 (HUT), Jurkat, and K-562 cell lines and hybridized to32P-labeled human ELA2, AZU1, PRTN3, ADN, and human β-actin cDNA probes as indicated for each blot.
