Points of the Announcement
- We found that electrolyzed hydrogen water (EHW) may affect the sensitivity of specific cancer cells to anticancer drugs.
- It was suggested that the suppression of autophagy in cancer cells related to mTORC1 signaling may affect the sensitivity to anticancer drugs by EHW.
- Further research development into cell tests, animal tests, and human clinical research is important for practical application.
Background
It has been clarified that the function of "autophagy *1," an intracellular component recycling system by which cancer cells protect themselves, is involved in the mechanism by which anticancer drugs become less effective in certain types of cancer cells. In fact, it has been reported that suppressing the function of autophagy may enhance the effect of anticancer drugs. In a joint study, Lecturer Satoshi Yano and Professor Taichi Hara of Waseda University's Faculty of Human Sciences, and Mr. Shigeru Kabayama of Nihon Trim Co., Ltd., demonstrated through RNA-seq *5 analysis and cellular experiments that electrolyzed hydrogen water *2 suppresses autophagy in association with the mTORC1 signal involved in the metabolic control of cells, potentially increasing sensitivity to 5-fluorouracil *3 and paclitaxel *4. Note that this result is based on cellular experiments and does not indicate efficacy, safety, reduction of side effects, or recommended intake methods in patients.

(1) What was known from previous research
Autophagy is a mechanism that breaks down and reuses intracellular components to maintain homeostasis. Cancer cells tend to have increased autophagy activity in the process of adapting to stress environments such as malnutrition and hypoxia, and this change has been reported to be involved in cell survival and drug resistance. Therefore, appropriately controlling autophagy activity has attracted attention as one of the factors influencing anticancer drug sensitivity. On the other hand, although antioxidant and anti-inflammatory effects have been reported for molecular hydrogen and electrolyzed hydrogen water, their relationship with autophagy control and anticancer drug sensitivity in cancer cells has not been fully clarified. In this study, we focused on this point and investigated the mechanism of action.
(2) What we tried to achieve newly this time, what was revealed, and the new methods developed for that purpose
In this study, we focused on autophagy as one of the factors involved in anticancer drug sensitivity and verified whether electrolyzed hydrogen water affects this process. First, when cellular responses to the administration of electrolyzed hydrogen water were comprehensively analyzed by gene expression analysis (RNA-seq), fluctuations in gene groups related to the mTORC1 pathway, which is involved in cell growth and metabolic control, were observed (Figure 1A). Furthermore, an increase in the phosphorylation of p70 S6K, a representative downstream molecule of mTORC1, was also confirmed, indicating the possibility that electrolyzed hydrogen water is associated with the activation of mTORC1 signaling (Figure 1B).
