Abstract
Nanosecond Pulsed Electric Fields (nsPEFs) treatment has demonstrated anti-tumor effects on various cancer cell lines. However, the use of this treatment in pancreatic cancer is limited. This study demonstrated that nsPEFs treatment effectively suppressed the proliferation and metastasis of pancreatic cancer cells, while also inducing DNA damage. Meanwhile, animal experiments have shown that nsPEFs effectively suppressed the growth of pancreatic cancer, even in cases where the tumor volume exceeded 500–600 mm3 at the initiation of treatment. Notably, a single treatment session was found to significantly inhibit tumor growth, while also showing no adverse effects on the main organs of the mice. RNA sequencing and bioinformatics revealed that seven key genes (CDK1, CENPA, UBE2C, CCNB2, PLK1, CCNA2, and CCNB14) were significantly correlated with the overall survival rate of patients with pancreatic cancer. Through the application of the competing endogenous RNA (ceRNA) hypothesis, two miRNAs (has-let-7b-5p and hsa-miR-193b-3p) and four lncRNAs (MIR4435-2HG, ZNF436-AS1, LINC01089, and MIR4435-2HG) were identified as significantly impacting the overall survival of pancreatic cancer patients. We have effectively developed an mRNA-miRNA-lncRNA network that has the potential to stimulate further investigation into the underlying mechanisms of nsPEFs on pancreatic cancer.
