WebSep 25, 2024 · Complementarily, AuPtAg nanozymes with catalase-like activity can ameliorate tumor hypoxia, significantly improving the GOx activity. As a result, the combination of AuPtAg-GOx with self-augmented photothermal ability and PD-L1 antibody can further escalate the antitumor efficacy. WebJun 3, 2024 · Upon initial dissociation of the host-guest interactions and hence Au NVs by cancer-specific reactive oxygen species (ROS), GOx is released to consume glucose and oxygen, generate H2O2 and induce the hypoxic TME, which act as the two keys for triggering burst payload release and promoter activation, thus allowing synergistic …
WebFurthermore, by transferring H 2 O 2 to O 2, the GOx/CAT-NCs could be applied to spatiotemporally controlled cancer therapy by reducing tumor hypoxia. Therefore, cutting off the glucose metabolism of cancer cells by long-term starvation therapy and damaging intracellular components by powerful PDT was a highly efficient strategy for synergistic ... WebJun 15, 2024 · Here, the prodrug tirapazamine (TPZ)-loaded human serum albumin (HSA)–glucose oxidase (GOx) mixture is prepared and modified with a …
WebGOX-immobilized hydrogels to induce hypoxia for in vitro culture of anchorage-independent acute myeloid leukemia cells Molm14 and anchorage-dependent hepatocellular carcinoma cells Huh7. We evaluated the effects of GOX-immobilized hydrogels on cancer cell fate, including viability, proliferation, and hypoxia-associated gene expression. 2. Web1 day ago · Hence, a possible hypoxia-reversal-dominated mechanism was proposed from the perspective of etiology that Pt-AuNS-GOx catalyzed the overexpressed H 2 O 2 in TME for O 2 replenishment to facilitate the decomposition of HIF-1α, and reinforce the oxygen-dependent OXD-like and GOx activities for synergistic cancer therapy (Fig. 7 g). Through ...
WebFeb 1, 2024 · GOx is a natural occurring oxido-reductase that can catalyze glucose into gluconic acid and hydrogen peroxide in the presence of oxygen. Therefore, the addition of GOx can not only cut off the nutrition of tumor tissues but also consume the oxygen in tumor tissues, making the tumor environment (TME) more hypoxic [23], [24].
