Outline of Research at the Start

角化は生物学的に細胞死のひとつであり皮膚組織構築のなかで重要な位置を占める。我々はこれまでにプロフィラグリンのN末領域(proFLG-ABT)が角化の過程で核内に移行しDNAを分解することを報告した。しかし、その詳細なメカニズムについては未だ明らかではない。本研究ではproFLG-ABTの核内移行におけるカルパイン1の役割、各種DNaseとproFLG-ABTとの関連、proFLG-ABTと核内で結合する蛋白質の探索に焦点をあて、表皮の角化におけるDNA分解機序の全容の解明を試みる。さらに、この研究で得られた知見をもとに効果的でかつ安全性の高い皮膚有棘細胞癌の新規治療法の開発に展開していく。

Outline of Final Research Achievements

In this study, we examined the mechanism of DNA degradation by the N-terminus of profilaggrin (proFLG-ABT). We first investigated the involvement of DNase1L2, DNase2, TREX2, and CAD in this process. However, no involvement was observed. In contrast, in differentiated keratinocytes, the N terminus of proFLG and apoptosis inducing factor (AIF) were colocalized within the nucleus and the cells were positive for TUNEL staining. Furthermore, DNA degradation was significantly inhibited by the suppression of AIF.
In the analysis of proteins that can bind to proFLG-ABT within the nucleus, we investigated the expression of ERH, SOCS7, and eIF6, which were confirmed to be expressed in the normal epidermis. Furthermore, in cutaneous squamous cell carcinoma (SCC), ERH was strongly expressed in the nucleus of tumor cells, and the proliferation of SCC cells (HSC-1 cells) was inhibited by the suppression of ERH.

Academic Significance and Societal Importance of the Research Achievements

本研究の特色は角化において重要な役割を担うフィラグリンを中心に表皮角化細胞のDNA分解機序を解析したことである。近年表皮角化細胞の細胞死はコルネオトーシスと呼ばれる特殊な細胞死であることが提唱され、この細胞死の機序の全容解明は表皮細胞生物学の発展のみならず様々な疾患の病態の解明や新規治療の開発にもつながると思われる。本研究ではカルパイン1-AIF系の細胞死への関与やフィラグリンと核内で結合する分子の機能など多くの新知見が見出されており、学術的にも社会的にもこの領域の発展に大きく寄与するものと期待される。
