TL;DR
Electrolyzed hydrogen water suppressed autophagy via mTORC1 activation and enhanced the anticancer effects of chemotherapy drugs in cancer cell models.
Key Finding
Electrolyzed hydrogen water suppressed autophagy in cervical and colorectal cancer cells and enhanced the cancer-killing effects of chemotherapy drugs in laboratory studies.
Summary
Researchers studied how electrolyzed hydrogen water (water treated with electricity to add hydrogen gas) affects cancer cells in laboratory dishes. They found that this water suppressed autophagy—a cellular recycling process that helps cancer cells survive chemotherapy drugs. When combined with common cancer drugs like 5-fluorouracil or paclitaxel, the hydrogen water made cancer cells more vulnerable and easier to kill.
Practical Takeaway
This is early laboratory research in cancer cells only—not human studies. While the results are interesting and suggest hydrogen water may help chemotherapy work better, it's far too preliminary to consider it a cancer treatment or supplement. Anyone undergoing cancer treatment should discuss any new substances with their oncologist before use.
Abstract
Autophagy is an intracellular recycling system that contributes to the maintenance of cellular homeostasis. However, by providing tolerance to various stressors, autophagy promotes the survival and proliferation of cancer cells and confers resistance to chemotherapy. Anticancer drugs activate autophagy, leading to drug resistance in cancer cells. Autophagy inhibitors, such as chloroquine and hydroxychloroquine, enhance the antitumor effects of anticancer drugs when used in combination with them. However, these inhibitors are associated with several adverse effects. Here, using genome-wide RNA sequencing analysis, we deciphered a novel function of electrolyzed hydrogen water (EHW) in suppressing autophagy by activating mammalian target of rapamycin complex 1 signalling. The combination of EHW with anticancer drugs, such as 5-fluorouracil or paclitaxel, which activate autophagy, significantly decreased the viability of cervical and colorectal cancer cells. Mechanistically, molecular hydrogen and trace elements in EHW may suppress autophagy and potentiate anticancer effects. Considering its safety, we propose that EHW can act as a novel adjuvant to anticancer therapy.
