【研究プロジェクト名および概要】
我々の講座では、泌尿器悪性腫瘍の発がん機構と治療抵抗性獲得を解明し、新規治療戦略を開発することを目標に、臨床・基礎の両面から研究を行っています。具体的な取り組みは次のとおりです。
当科は、日常臨床を通じて医師としての知識の習得、外科医としての技術の習得を目指していますが、同時に科学者としての視点も大切にしており、研究と向きあう姿勢が日々の診療で遭遇する疑問の解決に大いに役立つものと考えています。
Our department conducts both clinical and basic research with the overarching goal of elucidating the mechanisms of tumorigenesis and treatment resistance in urologic malignancies and developing novel therapeutic strategies. Our specific initiatives are as follows:
Analysis of Renal Cancer Tumorigenesis
We focus on the angiopoietin-like protein (ANGPTL) family, which promotes angiogenesis. In particular, we are investigating how ANGPTL2, known to act on vascular endothelial cells and monocytes, influences tumor progression using mouse models.
Genome-Wide Screening with CRISPR/Cas9
Using our proprietary screening system, we discovered that the transcriptional regulator Mediator complex plays a crucial role in the development of TFE3- rearranged renal cell carcinoma. We are currently investigating the detailed mechanism.
The same technology is also being applied to elucidate the molecular bases of castration resistance and PARP-inhibitor resistance in prostate cancer.
Novel Immunotherapy Targeting Tumor Immunity
We are evaluating natural compounds that activate macrophages in regional lymph nodes. Their ability to stimulate antitumor immunity is being tested in a subcutaneous bladder cancer xenograft mouse model.
Biomarker Discovery Using Clinical Specimens
Although immune-checkpoint inhibitors show remarkable efficacy in urologic cancers, non-responders and severe adverse events remain challenges. We therefore seek biomarkers that predict therapeutic response and adverse-event risk.
Through routine clinical practice, we strive to hone our medical knowledge and surgical skills while valuing a scientist’s perspective. We believe that a researchoriented mindset greatly aids in solving the clinical questions we encounter each day.
