Commun., 14, 1, 550, 2023.02, Myofibroblasts cause tissue fibrosis by producing extracellular matrix proteins,such as collagens. Humoral factors like TGF-β, and matrix stiffness areimportant for collagen production by myofibroblasts. However, themolecularmechanisms regulating their ability to produce collagen remain poorly characterised.Here, we show that vestigial-like family member 3 (VGLL3) is specificallyexpressed in myofibroblasts from mouse and human fibrotic heartsand promotes collagen production. Further, substrate stiffness triggers VGLL3translocation into the nucleus through the integrin β1-Rho-actin pathway. Inthe nucleus, VGLL3 undergoes liquid-liquid phase separation via its lowcomplexitydomain and is incorporated into non-paraspeckle NONO condensatescontaining EWS RNA-binding protein 1 (EWSR1). VGLL3 binds EWSR1and suppresses miR-29b, which targets collagen mRNA. Consistently, cardiacfibrosis aftermyocardial infarction is significantly attenuated in Vgll3-deficientmice, with increased miR-29b expression. Overall, our results reveal anunrecognised VGLL3-mediated pathway that controlsmyofibroblasts’ collagenproduction, representing a novel therapeutic target for tissue fibrosis.. 2. 仲矢 道雄, 渡健治, 田島充, TAKEO NAKAYA, 松田翔一, 西原弘朗, 山口裕嗣, 橋本明子, 西田光甫, AKIOMI NAGASAKA, 堀井雄馬, 小野達貴, Gentaro Iribe, Ryuji Inoue, TSUDA MAKOTO, Kazuhide Inoue, Akira Tanaka, Masahiko Kuroda, Shigekazu Nagata, Cardiac myofibroblast engulfment of dead cells facilitates recovery after myocardial infarction, JOURNAL OF CLINICAL INVESTIGATION, 10.1172/JCI83822, 127, 1, 383-401, 2017.01, 心筋梗塞時に心臓の線維化を担うのみと考えられていた筋線維芽細胞が、心筋梗塞時の死細胞を貪食する機能を持つことを世界に先駆けて見出した。そして、その貪食がMFG-E8という分子を介して行われていることを見出した。さらに、そのMFG-E8タンパク質を心筋梗塞後の心臓に投与すると、心筋梗塞後の死細胞の貪食が亢進し、心筋梗塞後の病態が改善することを見出した。. 3.

Commun. , 287, 1532, 2013.02, 生体内で死んだ細胞はマクロファージなどの貪食細胞によって積極的に取り込まれ、消化されて無くなってしまいます。この速やかな貪食は、死んだ細胞からの内容物の流出を防ぐ等、生体の恒常性を維持する上で極めて重要な役割を担っています。九州大学大学院薬学研究院薬効安全性学分野の黒瀬等教授と仲矢道雄准教授を中心とする研究グループ（九州大学大学院薬学研究院薬理学分野の井上和秀主幹教授、東京医科大学分子病理学講座の黒田雅彦主任教授、徳島大学疾患酵素学センター疾患プロテオミクス研究部門の小迫英尊准教授ら）は、このアポトーシス細胞の貪食にGRK6というタンパク質が関与している事を世界で初めて見出しました。GRK6を欠損したマウスは貪食能の低下が原因で全身性エリテマトーデスや鉄過剰症様の症状を呈しました。従って、GRK6はこれら疾患の治療に関する新たなターゲット分子となることが期待されます。　本研究成果は、平成25年2月26日（火）（現地時間）に英国科学雑誌 「Nature Communications」オンライン版に掲載されました。. 5.
