Outline of Research at the Start

ゲノム全体のDNA methylation statusのsurrogate markerであるLINE-1のamplification (転移・挿入)とがん進展との関わりが注目されている。本研究では、肝癌やその前癌病変であるNASHにおけるLINE-1の転移・挿入部位を同定し、発がんやがん進展に関わる遺伝子群や経路の新たな知見を得ることを目的とする。この成果はsurrogate markerとしてのLINE-1の地位の確立と新たな治療ターゲットの発見につながり、肝癌の早期発見、予後予測、及び改善に重要な意義を持つと考える。

Outline of Final Research Achievements

LINE-1 methylation in the nonhepatitis viral background liver was significantly higher than that of hepatitis B infection (74.9 ± 2.6) and hepatitis B and C virus overlap infection cases (70.7 ± 6.9), suggesting an effect of hepatitis virus infection on DNA methylation. Based on the new Inuyama classification, fibrosis was classified as F0 to F4 and divided between two groups, F0-3 and F4. A comparison of the association with LINE-1 methylation in non-cancerous areas between the two groups showed no significant difference (p = 0.47). These results suggest that the level of LINE-1 methylation in the background liver varies according to its ethiology, but is not affected by the degree of fibrosis. When we evaluated the number of LINE-1 copies in noncancerous areas using excisional frozen specimens, we also evaluated the number of LINE-1 copies in each background liver and found no statistically significant difference between the hepatitis virus and nonhepatitis virus groups (p=0.29).

Academic Significance and Societal Importance of the Research Achievements

近年増加傾向にある非肝炎ウイルスによるHCCの理解のために行った研究である。背景肝の炎症と癌の予後予測因子であるDNA メチル化のマーカーであるLINE-1のメチル化を評価した。本研究により、LINE-1のメチル化は肝繊維化によらず、背景疾患(B型肝炎、C型肝炎あるいは非肝炎ウイルス性)により異なることが示唆された。背景肝のLINE-1のcopy number数の検討においては、NBNCが最も低値でHBVが高値を示すことがわかり、背景肝の違いによりLINE-1の増幅が異なることが示唆された。症例を増やして検討することにより、LINE-1の肝炎における重要性を評価しうると考える。
