Four groups of Sprague-Dawley rats were given Ferastral, an iron-poly(sorbitol-gluconic acid) complex (IPSG) or Imferon, an iron-dextran complex, intramuscularly twice a week for 17 weeks. The experiment lasted for 95 weeks. Each compound was given to two groups, one low dose group and one high dose

Colorectal cancer (CRC), which occurs at the junction of the rectum and sigmoid colon, is a common malignancy associated with poor prognosis and high mortality worldwide. The exopolysaccharide (EPS1-1), isolated from the fermentation broth of Rhizopus nigricans

Doxorubicin is widely used anticancer drug; however, use of doxorubicin is limited. Under externally applied magnetic field, magnetic agents can help to transport drug directly to tumor. Folate receptor is overexpressed in ovarian carcinomas. In this study, we aimed to develop magnetically

Efficient drug delivery into tumor cells while bypassing many biological barriers is still a challenge for cancer therapy. By taking advantage of the palladium (Pd)-mediated in situ activation of a prodrug and the glucose oxidase (GOD)-based β-D-glucose oxidation reaction, we developed a

Emerging nanocatalytic tumor therapies based on nontoxic but catalytically active inorganic nanoparticles (NPs) for intratumoral production of high-toxic reactive oxygen species have inspired great research interest in the scientific community. Nanozymes exhibiting natural enzyme-mimicking catalytic

Over the past 3 years, glucose oxidase (GOx) has aroused great research interest in the context of cancer treatment due to its inherent biocompatibility and biodegradability, and its unique catalytic properties against β-d-glucose. GOx can effectively catalyze the oxidation of glucose into gluconic

Nanozymes as artificial enzymes that mimicked natural enzyme-like activities have received great attention in cancer diagnosis and therapy. Biomimetic nanozymes require more consideration regarding complicated tumor microenvironments to mimic biological enzymes, thus achieving superior nanozyme

Starvation therapy to slow down the tumor growth by cutting off its energy supply has been proposed to be an alternative therapeutic strategy for cancer treatment. Herein, glucose oxidase (GOx) is loaded into stealth liposomes and act as the glucose and oxygen elimination agent to trigger the

Chaos and natural evolution of tumor system have become two reasons of the failure of tumor therapies. Selectively targeting chaotic tumor systems to induce a "butterfly effect" is promising in constructing non-interventional and effective strategy for tumor therapy. Herein, we demonstrate

Synergistic cancer starvation/ROS-mediated/chemo-therapy is developed through a cascade reaction with enzyme glucose oxidase (GOX) modified on the surface of an Fe-based metal organic framework (MOF(Fe)) and drug camptothecin (CPT) loaded into the cavities of MOF(Fe). Once internalized by tumor

Intratumoral glucose depletion-induced cancer starvation represents an important strategy for anticancer therapy, but it is often limited by systemic toxicity, nonspecificity, and adaptive development of parallel energy supplies. Herein, we introduce a concept of cascaded catalytic nanomedicine by

Tumor-activatable ultrasmall nanozyme generation is an unprecedented strategy to overcome intrinsically fatal defects of traditional reactive oxygen species (ROS)-based nanoagents for deep tumor penetration, including limited tissue-penetrating depth of external energy, heavy reliance on oxygen and

Traditional tumor treatments suffer from severe side effects on account of their invasive process and inefficient outcomes. Featuring unique physical microenvironment, the tumor microenvironment (TME) provides a new research direction for designing more efficient and safer treatment paradigm. In

Glucose oxidase (GOX) can convert glucose into gluconic acid and hydrogen peroxide (H2O2), which is potentially useful for synergistic cancer-starving and oxidation therapy. Herein we demonstrate a glucose-responsive nanomedicine made of GOX-polymer nanogels to regulate H2O2 production for

The tumor microenvironment (TME) has been increasingly recognized as a crucial contributor to tumorigenesis. Based on the unique TME for achieving tumor-specific therapy, here a novel concept of photothermal-enhanced sequential nanocatalytic therapy in both NIR-I and NIR-II biowindows is proposed,
