The delivery of molecular hydrogen (H2) is increasingly recognized for its potential in precision immunomodulation, primarily through multiple pathways such as antioxidant action, modulation of inflammatory factors, and inhibition of apoptosis. These effects contribute to a balanced and functional immune system, highlighting the therapeutic promise of H2 in various inflammatory conditions. However, t

Inulin consumption and dihydrogen (H2) administration both exert antitumor effects on preclinical models as well as in clinical trials. As H2 is one of the major byproducts of inulin fermentation by bacterial species of the gut microbiota (GM), we hypothesized that H2 could mediate the antitumor effects of inulin. To provide evidence in favor of this hypothesis, we first determined the pattern of

Molecular hydrogen is gaining increasing attention as an antioxidant, anti-
inflammatory, and antiapoptotic agent. Once considered an inert gas, it reveals current
therapeutic potential among others in inflammatory diseases, cancer, and sports medicine,
among others. The present review aims to provide a consistent summary of the findings
of the last twenty years on the use of molecular hydrogen in

Background: Cancer remains a challenging target to cure, with present therapeutic methods unable to exhibit restorative outcomes without causing severe negative effects. Molecular hydrogen (H2) has been reported to be a promising adjunctive therapy for cancer treatment, having the capability to induce anti-proliferative, anti-oxidative, pro-apoptotic and anti-tumoural effects.

Objective. Molecular hydrogen (H2) has been considered a potential therapeutic target in many cancers. Therefore, we sought to assess the potential effect of H2 on colorectal cancer (CRC) in this study.
Methods. The effect of H2 on the proliferation and apoptosis of RKO, SW480, and HCT116 CRC cell lines was assayed by CCK-8, colony formation, and flow cytometry assays. The effect of H2 on tumor growt

As previously reported, hydrogen gas improves the prognosis of patients with cancer by restoring exhausted CD8+ T cells into active CD8+ T cells, possibly by activating mitochondria. As mitochondrial activators exhibit synergistic effects with nivolumab, the current study investigated whether hydrogen gas also affects the clinical outcomes of nivolumab. A total of 42 of 56 patients with lung cance

In recent years, many studies have shown that hydrogen has therapeutic and preventive effects on various diseases. Its selective antioxidant properties were well noticed. Most of the ionizing radiation-induced damage is caused by hydroxyl radicals (.OH) from radiolysis of H2O . Since hydrogen can mitigate such damage through multiple mechanisms, it presents noteworthy potential as a novel radio-pro

Exhausted cluster of differentiation (CD)8+ T cells lose immunological activity due to mitochondrial dysfunction caused by peroxisome proliferator‑activated receptor γ coactivator 1α (PGC‑1α) inactivation, resulting in a poor prognosis in patients with cancer.

Studies on molecular hydrogen have evolved tremendously from its humble beginnings and have continued to change throughout the years. Hydrogen is extremely unique since it has the capability to act at the cellular level. Hydrogen is qualified to cross the blood brain barrier, to enter the mitochondria, and even has the ability to translocate to the nucleus under certain conditions. Once in these i

Background: Mitochondria are the major source of oxidative stress. Acute oxidative stress causes serious damage to tissues, and persistent oxidative stress is one of the causes of many common diseases, cancer and the aging process; however, there has been little success in developing an effective antioxidant with no side effect.

Radiotherapy is an important modality of cancer treatment. Radiation pneumonitis is a major obstacle to increasing the radiation dose in radiotherapy, and it is important to prevent this radiation-induced complication.

Purpose: Cisplatin is a widely used anti-cancer drug in the treatment of a wide range of tumors; however, its application is limited by nephrotoxicity, which is affected by oxidative stress. We have reported that molecular hydrogen (H(2)) acts as an efficient antioxidant (Ohsawa et al. in Nat Med 13:688-694, 2007). Here we show that hydrogen efficiently mitigates the side effects of cisplatin by r
