BACKGROUND A unique immunosuppressant, FTY720, selectively induces apoptosis in activated lymphocytes, but not in other hematopoietic cells. The potential that this unique mechanism could provide anticancer potential by inducing apoptosis in the human renal cancer cell line, ACHN, which is resistant to cisplatin, and its molecular pathway was investigated.(More)
We have developed a novel bladder preservation therapy, balloon-occluded arterial infusion (BOAI) of cisplatin/gemcitabine, concomitantly with hemodialysis, along with concurrent irradiation [the so-called 'OMC (Osaka Medical College) regimen']. The OMC regimen delivers an extremely high concentration of anticancer agent to the site of a tumor without(More)
ComA of Streptococcus is a member of the bacteriocin-associated ABC transporters, which is responsible for both the processing of the propeptide ComC and secretion of the mature quorum-sensing signal. The quorum-sensing system is a bacterial intercellular communication system implicated in various functions including biofilm formation. In this study, the(More)
We investigated the effect of balloon-occluded arterial infusion (BOAI) of anticancer agent (cisplatin/gemcitabine), used concomitantly with hemodialysis, which delivers an extremely high concentration of anticancer agent to the site of a tumor without systemic adverse effects, along with concurrent radiation (referred to as the OMC-regimen) in patients(More)
OBJECTIVES We tested the usefulness of balloon-occluded arterial infusion (BOAI) of anticancer agent (cisplatin/gemcitabine), concomitant with hemodialysis, which delivers an extremely high concentration of anticancer agent to the site of a tumor without systemic adverse effects, along with concurrent radiation [Osaka-Medical College (OMC)-regimen] in(More)
OBJECTIVE We tested the usefulness of combined therapy using balloon-occluded arterial infusion (BOAI) of cisplatin and hemodialysis, which delivers an extremely high concentration of cisplatin to the site of a tumor without systemic adverse effects, with concurrent radiation in patients with locally advanced bladder cancer. METHODS Patients underwent(More)
In this study, we investigated the novel bladder preservation therapy, the balloon-occluded arterial infusion (BOAI) of cisplatin/gemcitabine, concomitantly with hemodialysis, along with concurrent irradiation [the 'Osaka Medical College (OMC)-regimen'] in patients >70 years of age with muscle-invasive bladder cancer. Eighty-three such patients were(More)
We have developed a novel form of bladder preservation therapy [OMC (Osaka Medical College)-regimen] involving balloon-occluded-arterial-infusion (BOAI) of an anticancer agent (cisplatin/gemcitabine), used concomitantly with hemodialysis, which delivers an extremely high concentration of anticancer agent to the site of a tumor without systemic adverse(More)
Nuclear factor-kappaB (NF kappaB) plays a pivotal role in cancer progression. In this study, we developed a decoy cis-element oligo-deoxyribonucleic acid against NF kappaB-binding site (NF kappaB-decoy), which effectively inhibits NF kappaB activity, and tested the effect of combined therapy comprising local transfection of NF kappaB-decoy into the liver(More)
Gamma-aminobutyric acid (GABA) was first discovered as an inhibitory neurotransmitter in the central nervous system (CNS) and has been reported to have a variety of functions, including regulation of cell division, cell differentiation and maturation, and to be involved in the development of certain cancers outside the CNS. In the present study, using the(More)
