Abstract

Abstract Hydrogen can be used as an anti-cancer treatment. However, the continuous generation of H2 molecules within the tumor is challenging. Magnesium (Mg) and its alloys have been extensively used in the clinic as implantable metals. Here we develop, by decorating platinum on the surface of Mg rods, a Mg-based galvanic cell (MgG), which allows the continuous generation of H2 in an aqueous environment due to galvanic-cell-accelerated water etching of Mg. By implanting MgG rods into a tumor, H2 molecules can be generated within the tumor, which induces mitochondrial dysfunction and intracellular redox homeostasis destruction. Meanwhile, the Mg(OH)2 residue can neutralize the acidic tumor microenvironment (TME). Such MgG rods with the micro-galvanic cell structure enable hydrogen therapy to inhibit the growth of tumors, including murine tumor models, patient-derived xenografts (PDX), as well as VX2 tumors in rabbits. Our research suggests that the galvanic cells for hydrogen therapy based on implantable metals may be a safe and effective cancer treatment.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Mg2+-activated osteogenic pathways (e.g., Wnt signaling) act synergistically with M2 macrophage-derived reparative factors to promote collagen deposition and bone formation.

    “Concurrently, Mg2+-activated osteogenic pathways (e.g., Wnt signaling) act synergistically with M2 macrophage-derived reparative factors to promote collagen deposition and bone formation [36,66];”

    From Nanocatalytic magnesium osteoimplants with biodegradable self-adaptive interfaces for therapeutic repair of infected bone defects (2026) · cites this paper as [36]

    The Results section on in vivo hydrogen therapy reports changes in tumor immune cells, including fewer MDSCs and more CD8+ T cells, not M2 macrophage-derived repair. Searches of our copy for Wnt signaling, osteogenesis, collagen deposition, and bone formation found no passage addressing the claimed synergy. (LLM, conf=0.78)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
