RNA from U937 cells cocultured with H pylori NCTC11638 (wild type, w) or 11638-△ vacA (mutant type, m) or RNA from normal cells (c) were sepa-rated by agarose electrophoresis, transferred onto nylon membranes, and probed with the human cDNAs as follows: NM_002817 (PSMD13), and NM_004517 (ILK). Control blots with human β-actin were provided.
