KeywordsAngiogenin / 口腔癌骨浸潤
Outline of Research at the Start

血管新生因子Angiogenin(ANG)は様々な癌細胞から産生され,血管内皮細胞表面の受容体PlexinB2を介して血管新生を促進する.最近我々は,口腔癌の骨浸潤部にANGが高発現していることを確認した.骨微小環境において口腔癌細胞が産生するANGは,破骨細胞形成を促進し,顎骨破壊を促進しているかという点について,ANGノックアウトマウス(KOマウス)および口腔癌骨浸潤動物モデルを用いてその解明を目指す.

Outline of Final Research Achievements

Angiogenin (ANG), an angiogenic factor, is produced by various cancer cells and promotes angiogenesis via the receptor Plexin B2 on the surface of vascular endothelial cells. We recently confirmed that ANG is highly expressed in bone invasion areas of oral cancer and that ANG promotes osteoclast formation.
The question that arises from these findings is whether ANG produced by oral cancer cells in the bone microenvironment promotes osteoclast formation and jaw bone destruction. We aim to elucidate this using an oral cancer bone invasion animal model.

Academic Significance and Societal Importance of the Research Achievements

本研究で骨破壊におけるANGの機能を解析することによって,今まで未知であった骨代謝疾患の原因が見つかるかもしれない.また骨粗鬆症の治療法や乳癌や前立腺癌の骨転移の制御へ応用できる.ANG受容体であるPlexinB2は神経軸索ガイダンス因子Semaphorinの受容体でもある.骨微小環境における血管新生と神経新生のクロストークの一部をANGが担っていると考えられ,新たな学術的潮流を作り出せる可能性がある.
