Autophagy and enhanced chemosensitivity in experimental pancreatic cancers induced by noninvasive radiofrequency field treatment.
This study tested noninvasive 13.56 MHz radiofrequency electric fields as a treatment adjunct for pancreatic ductal adenocarcinoma in cell lines and mouse xenograft models. The authors report RF exposure caused cytotoxicity in PDAC cells via autophagy (not apoptosis) and that normal pancreatic ductal epithelial cells did not show these effects. RF combined with subtoxic gemcitabine enhanced antitumor effects in mice compared with either treatment alone, with no systemic toxicity observed in histopathology.
Key points
- The study evaluated 13.56 MHz RF electric fields alone and combined with gemcitabine against PDAC.
- RF exposure was reported to induce autophagy in PDAC cells and produce substantial cytotoxicity.
- Apoptosis was not observed as the primary mechanism in the reported RF effect.
- Normal pancreatic ductal epithelial cells reportedly did not show the RF-associated effects seen in cancer cells.
- Autophagosomes persisted for 24β48 hours after RF exposure before declining.
- Adding subtoxic gemcitabine reportedly inhibited recovery from RF-induced autophagy and increased cytotoxicity.
- In mouse xenograft models, RF plus gemcitabine showed superior antitumor effects versus either alone.
- No evidence of systemic toxicity was reported based on histopathology.
