Nobuya Haysahi, Changes in seed surface molecular structures due to oxygen plasma irradiation, The 7th International Symposium on Plasma & Fine Bubbles to Agriculture and Aquaculture (7th ISPFB 2023) , 2023.05, In this study, oxygen plasma irradiation to seeds was applied to the cultivation of agricultural products. So far, by irradiating the seeds of typical agricultural products such as carrots, cucumbers, and radishes with oxygen plasma, the effects of growth enhancement and shortening the cultivation time have been obtained.

Sterilization effect depends on the ozone treatment time when the ozone concentration is fixed at high concentration. IR spectra of fruits surface indicate that the reduction reaction is occurred in fruits surface by the plasma treatment.

The RANKL that is the differentiation inducer in the culture medium is modified by the plasma irradiation, and lose the function. Oxygen plasma irradiation to the cells without the culture medium at lower discharge voltage leads to the increase of the cell number.

When the cells are irradiated with oxygen plasma, the intracellular active oxygen in cancer cells increases comparing with that in normal cells. Activity of caspase-3/7 in oral cancer cells, which is a kind of major biological reactions of the apoptosis, increases after oxygen plasma irradiation..

61. 林 信哉、小野大帝、米須 章、田代康介、合島怜於奈, Growth enhancement and gene expression of plants induced by oxygen plasma irradiation, International Toki Conference 2017, 2017.12, 植物種子の遺伝子発現解析とDNAメチル化定量分析を行い、プラズマ照射効果の発現機構としてのエピジェネティクスを確認した。シロイヌナズナの葉面積と全長の増加は、活性酸素種の照射線量に関係する。プラズマ照射された種子から生長した植物の生長速度は、生育期間中の未処理の種子の生育速度よりも速い。シロイヌナズナの種子の遺伝子発現は、酸素プラズマ照射のために数十の遺伝子がアップレギュレートされていることを示している。クロマチン構造およびDNAメチル化などの染色体領域の構造が改変されることが見出され、エネルギー産生系の増強を示す。ヒストンH1.2の減少およびDMEの増加は、ヒストン周辺の遺伝子巻取りおよび遺伝子の脱メチル化をそれぞれ緩やかに誘発する。したがって、遺伝子のエピジェネティックな改変により、酸素プラズマの照射効果の継承が起こることが明らかとなった。.

63. 林 信哉,中野 陸,小野大帝,田代康介,久原 哲,合島怜於奈, Modification of gene expression of plants induced by active oxygen species in oxygen plasma, IUMRS-ICAM 2017, 2017.09, 遺伝子発現解析とDNAメチル化定量解析を行い、エピジェネティクスがプラズマ照射効果の遺伝機構であることを確認した。 ヒストンH1.2の減少およびDMEの増加から、ヒストンの周りの遺伝子巻取りの緩和および遺伝子の脱メチル化が明らかとなった。 DNA脱メチル化が緩慢であることから、遺伝子発現の増加が示唆された。 また、DNAメチル化量とプラズマ中の励起酸素量が酸素ガス圧力に関して同様の傾向を有することが分かった。 以上の結果から、活性酸素種の照射により遺伝子のエピジェネティックな改変が生じ、増殖促進効果の遺伝機構がエピジェネティクスに起因すると結論づけられた。.
