dc.description.abstractThe aim of this study is to determine the incorporations of radiolabeled bleomycin (I-131-BLM) and bleomycin-glucuronide (I-131-BLMGLU) on PC-3 (human prostate carcinoma cell line), Caco-2 (human colon adenocarcinoma cell line), Hutu-80 (Human Duodenum adenocarcinoma cell line), and A549 (Human lung adenocarcinoma epithelial cell line) cancerous cell lines. For this purpose, BLM and BLMGLU enyzmatically synthesized were labeled with I-131, quality control studies were done and the incorporation yields of I-131-BLM and I-131-BLMGLU on these cell lines were measured. Quality-control studies showed that the radiolabeling yields were obtained as 95% and 90% for I-131-BLM and I-131-BLMGLU, respectively. Also, as a result of the cell culture studies, it was found that I-131-BLM and I-131-BLMGLU had higher incorporation on PC-3 cells than that of other cell lines. In addition to this, it was reported that the incorporation yield of I-131-BLMGLU was higher than that I-131-BLM. At the end of the study, cytotoxicities of BLM and BLMGLU on PC-3 cancerous cell line were inspected and fluorescent images of BLM and BLMGLU were taken on PC-3 cells by using fluorescein isothiocyanate. In conclusion, cell culture studies demonstrated that the incorporation values of I-131-BLMGLU on the four cell lines were about five to six times higher than I-131-BLM. Radiolabeled glucuronide derivatives can be used in cancer therapy and tumor imaging, depending on the properties of radioiodine for the beta-glucuronidase-rich tissues because glucuronidation leads to rapid and higher incorporation on adenocarcinoma cells.
