基礎研究

腎泌尿器科基礎研究室では、泌尿器科癌、特に尿路上皮癌、腎癌、精巣腫瘍に対する分子生物学的研究並びに、トランスレーショナルリサーチを行っています。さらに、排尿障害、生殖医療、再生医療、人工知能の研究にも積極的に取り組んでいます。

Major Scientific Interests of the Group
The molecular pathogenesis in urologic cancers, especially urothelial carcinoma, renal cell carcinoma and testicular tumor, and their translational research. Fields of bladder dysfunction, infertility, regenerative medicine and artificial intelligence as well.

Projects for Regular Students in Doctoral or Master’s Programs
1) Identification of novel oncogene signals and tumor immune micro-environment in urothelial cancer.
2) The effect and mechanism of ELOVL (Elongation of very long chain fatty acids) in the proliferation of renal cancer.
3) The antitumor immunity of cationized liposomal trehalose-6,6-dimycolate isolated from Mycobacterium in a syngeneic murine bladder cancer model.
4) Elucidation of carcinogenesis and invasion mechanisms in bladder cancer via ASIC (Acid-sensing ion channels) and ENaC (epithelial sodium channels).
5) The molecular mechanism of bladder dysfunction due to sleep/circadian rhythm disorder.
6) Repair and regeneration of bladder dysfunction using purified Human Skeletal Muscle-Derived Stem Cells.
7) Detection of urologic cancer risk using serum trace elements.

Study Programs for Short Stay Students (one week – one trimester)
Clinical clerkship/Elective: surgery (robotic, laparoscopic, reduced port, open, transurethral, micro etc), clinical conference, outpatient/inpatient care and laboratory meeting.
