Outline of Final Research Achievements

Adult mice with reduced expression of Fibulin-4 in the dermis were generated. The back skin of these mice was harvested for phenotypic analysis of the dermis. The back skin of mice with reduced dermal Fibulin-4 expression showed a tendency towards defective formation of elastic and collagen fibres and reduced dermal thickness compared to normal mouse back skin.
Although we were able to show that reduced Fibulin-4 expression results in the hypoplasia of collagen fibres during normal dermal development, further studies are needed to determine whether the suppression of Fibulin-4 expression during wound healing suppresses fibrosis.

Academic Significance and Societal Importance of the Research Achievements

異常なコラーゲン線維形成の原因の一つと考えられる線維化を抑制するために、コラーゲン架橋酵素LOXの酵素活性を制御するための治療標的分子として、Fibulin-4が候補となりうる可能性を示唆する結果が得られた。
LOXの酵素活性化を阻害する分子として、古くからβアミノプロピオニトリル(BAPN)が知られてが、BAPNには神経毒性などの副作用があるため臨床使用することは難しい。そこで、LOXの酵素活性化に必須の分子Fibulin-4を標的としてLOXの機能を阻害することができれば、線維化治療の標的分子になりうる。繊維化病変に対する治療薬は少ないので、治療薬ができればその社会的意義は大きいと思われる。
