Outline of Final Research Achievements

It is critical to clarify the molecular mechanism of colitic caner for improving the prognosis of ulcerative colitis. We have elucidated the impact of extra-pulmonary surfactant protein d (SP-D) on UC. This experiment aims for clarifying the correlation of SP-D with colitic caner.
Comparing SP-D knockout (KO) mouse and wild mouse by using colitic caner mouse model with dextran sulphate sodium and azoxymethane, higher incidence and more number of tumor were observed in SP-D KO mouse. Consequently, SP-D is suggested to play a role on colitic cancer.

Academic Significance and Societal Importance of the Research Achievements

難治性炎症性腸疾患である潰瘍性大腸炎において,2次的に発症する炎症性発癌は予後に影響を与える問題点の1つであり,早期発見,発症予防は非常に重要である.本研究結果からSP-Dが潰瘍性大腸炎の病勢だけでなく,炎症性発癌にも関与していることが示唆され,例えばバイオマーカーや予防治療に応用することで,先述の課題解決に1筋の光を照らす可能性が期待できる.
