Outline of Final Research Achievements |
Molecular mechanism of cancer development and malignant progression is still unknown. We identified a CDCP1 protein as a potential regulator of acute response leading to compensatory adaptations after renal failure. CDCP1 is stably expressed in proximal renal tubules, where it promotes compensatory regrowth through cell growth and extracellular matrix rearrangement by spatial activation of STAT3-MMP axis. Meanwhile, CDCP1 is highly expressed in some renal cancer cells and induces cancer development and collective migration/invasion by upregulation of the STAT3-MMP pathway. These findings suggest that CDCP1 can facilitate renal repair, but promote cancer development and malignancy by activation of same signaling axis.

Academic Significance and Societal Importance of the Research Achievements |
がんは死因の一位であり、現在もその割合が増加し続けている。腎臓がん発症の原因のひとつに、腎臓病の進行が考えられているが、2つの疾患をつなぐメカニズムは不明のままであった。申請者は、腎臓の機能維持に重要なタンパク質CDCP1を同定した。その一方で、このタンパク質が過剰に増えた場合にはがん細胞の発生と悪性化を引き起こすことを明らかにした。以上の結果から、CDCP1の異常な発現が細胞がん化を引き起こす要因のひとつであることを明らかにした。このことは、腎臓病時のCDCP1の発現のコントロールががん化抑制に重要である可能性を示唆している。
