低温等离子体(LTP)是临床实践中一种有前途的癌症治疗方法。在这项研究中,使用氦气介电阻挡放电等离子体来产生 LTP。 LTP 处理后,肺癌细胞(CALU-1 和 SPC-A1)的细胞外和细胞内活性物质显着增加。细胞活力和凋亡测定表明,LTP 分别抑制细胞活力和诱导细胞死亡。此外,Western blotting首次揭示LTP通过VEGF/VEGFR2/RAS/ERK轴抑制CALU-1细胞的生长。结果表明,LTP诱导的ROS和RNS可以通过VEGF/VEGFR2/RAS/ERK轴抑制肺癌细胞的生长。这些发现加深了我们对LTP抑制肺癌机制的认识,并有利于其临床应用。
Low temperature plasma (LTP) is a promising cancer therapy in clinical practice. In this study, dielectric barrier discharge plasma with helium gas was used to generate LTP. Significant increases in extracellular and intracellular reactive species were found in lung cancer cells (CALU-1 and SPC-A1) after LTP treatments. Cells viability and apoptosis assays demonstrated that LTP inhibited cells viability and induced cells death, respectively. Moreover, Western blotting revealed that the growth of CALU-1 cells was suppressed by LTP via the VEGF/VEGFR2/RAS/ERK axis for the first time. The results showed that LTP-induced ROS and RNS could inhibit the growth of lung cancer cells via VEGF/VEGFR2/RAS/ERK axis. These findings advance our understanding of the inhibitory mechanism of LTP on lung cancer and will facilitate its clinical application.
