In adult T-cell leukemia/lymphoma (ATL), it is difficult to achieve remission and the reason for the resistance to chemotherapeutic agents may be linked to the presence of multidrug resistance (MDR) proteins. Lung resistance-related protein (LRP), multidrug resistance-associated protein and P-glycoprotein are three MDR proteins which we examined in ATL cells using multiparametric flow cytometry...

objective(s): acquisition of tnf-α resistance plays role in the onset and growth of malignant tumors. previous studies have demonstrated that mcf-7 cell line and its doxorubicin resistant variant mcf-7/adr are resistant against the cytotoxic effects of tnf-α. in this study, we investigated the role of akt activation in resistance of mcf-7 and mcf-7/adr against tnf-α cytotoxicity. materials and ...

yersinia enterocolitica is rapidly emerging worldwide as an enteric pathogen and has become a major cause of diarrhea even in developed countries. the aim of this study was to characterize and genetic diversity analysis among y. enterocolitica strains isolated from fish and chicken sources.from 44 strains, 55% (24 strains) found to be positive for y. enterocolitica by colony morphology, biochem...

BACKGROUND To identify novel proteins involved in multidrug resistance in chronic myeloid leukemia (CML). MATERIALS AND METHODS Comparative proteomics was used to screen multidrug resistance-related proteins from K562 and K562/A02; the differently expressed proteins were further confirmed by western blot and real-time PCR. short hairpin RNA (shRNA) assay was applied to determine the relations...

The aim of this study was to investigate the effect of treatment of experimental ovarian cancers with targeted cytotoxic analogs as single compounds and in combination. Targeted cytotoxic analogs of bombesin (AN-215), somatostatin (AN-238), and luteinizing hormone-releasing hormone (AN-207) consisted of 2-pyrrolinodoxorubicin (AN-201) linked to the respective peptide carrier. AN-238 at 200 nmol...
