Outline of Final Research Achievements

The prognosis of osteosarcoma has not changed over the past two decades; the prognosis for patients with lung metastasis is still poor and the development of new treatments is urgently required. Cold plasma-stimulated medium are promising novel anti-cancer tools due to their strong anticancer activities and high tumor-selectivity.Here we assessed the anti-tumor activity of another PSM prepared using transfusion(PLAST)toward osteosarcoma cell lines. PLAST strongly suppressed the growth of mouse and human and murine osteosarcoma cell lines while it had smaller effects on that of human and murine osteoblast cell lines. PLAST-induced cell death was not inhibited by caspase inhibitors and accompanied by minimum autophagic flux. Moreover, the cytotoxic effects of PLAST were not suppressed by various pharmacological apoptosis or autophagy inhibitors. It could be a candidate for a novel treatment for osteosarcoma with apoptosis resistance, though further elucidation of mechanism is necessary.

Academic Significance and Societal Importance of the Research Achievements

以前よりプラズマを腫瘍細胞に直接照射した研究は報告されてきたが、直接照射できる腫瘍は限られる。我々を含むいくつかの研究チームは、プラズマ照射溶液を使用した抗腫瘍効果を報告した。本研究では、活性化培養液が常温でも殺細胞効果を示したのは臨床応用に向け意義あるものであった。
さらに、プラズマ照射液は骨芽細胞株に比較して、骨肉腫細胞株に有意に強い細胞増殖の抑制効果をみるため、正常細胞への侵襲の少ない抗腫瘍効果を持つ可能性が示唆される。このことは、実臨床において安全度が高いものと考える。プラズマ活性化補液療法の確立は、骨肉腫患者の予後を改善すると同時に、より副作用の少ない治療法として期待される。
