Outline of Final Research Achievements |
We investigated the clinical significance of p38 MAPK in bladder cancer, in particular focusing on the impact of states of p38 MAPK on chemotherapy resistance.Our findings revealed that p38 MAPK was activated in gemcitabine resistant cell lines. p38 MAPK might contribute chemoresistant manner and have high potential as a therapeutic target of chemo-resistant urotherial carcinoma.

Academic Significance and Societal Importance of the Research Achievements |
転移を有する進行性尿路上皮癌の治療は主に化学療法が用いられるが、最終的には化学療法耐性となり十分な治療効果を得ているとは言い難い。我々は尿路上皮癌におけるp38の発現と化学療法耐性に着目し解析を行い、尿路上皮癌におけるp38のリン酸化は化学療法耐性と関係しp38のリン酸化を標的とする治療は抗がん剤耐性を克服する新規治療法となる可能性があると考えられた。
