DNA damage induced by the topoisomerase I inhibitor SN38 activates cell cycle checkpoints which promote cell cycle arrest. This arrest can be abrogated in p53-defective cells by the Chk1 inhibitor 7-hydroxystaurosporine (UCN-01). Previously, we compared p53 wild-type MCF10A cells with derivatives whose p53 function was inhibited by over-expression of the tetramerization domain (MCF10A/OD) or ex...
Pancreatic carcinoma is one of themost aggressive tumor entities, and standard chemotherapyprovides only modest benefit. Therefore, specific targeting of pancreatic cancer for early diagnosis and therapeutic intervention is of great interest. We have previously shown that the cellular receptor for Shiga toxin B (STxB), the glycosphingolipid globotriaosylceramide (Gb3 or CD77) is strongly increa...

To investigate the possible involvement of P-glycoprotein (P-gp), multidrug resistance-associated protein (MRP), and/or other glutathione S-conjugate export pump (GS-X pump) family members on the active efflux of irinotecan [(7-ethyl-10-[4-(1-piperidino)-1-pipertidino)-1-piperidino]carb onylox y camptothecin (CPT-11)] and its metabolites, as well as their contribution to the acquisition of resi...
