Tumor microenvironment activation amplify oxidative stress promoting tumor energy remodeling for mild photothermal therapy and cuproptosis.

Tumor metabolic reprogramming requires high levels of adenosine triphosphate (ATP) to maintain treatment resistance, which poses major challenges to chemotherapy and photothermal therapy. Especially, high levels of ATP promote copper ion efflux for limiting the curative effect of cuproptosis. Here, an HS-responsive mesoporous CuCl(OH)-loading chemotherapeutic cisplatin (CDDP) was synthesized, and the final nanoparticle, CDDP@CuCl(OH)-CDs (CDCuCDs), was encapsulated by electrostatic action with carbon dots (CDs).

HS-driven chemotherapy and mild photothermal therapy induced mitochondrial reprogramming to promote cuproptosis.

The elevated level of hydrogen sulfide (HS) in colon cancer hinders complete cure with a single therapy. However, excessive HS also offers a treatment target. A multifunctional cascade bioreactor based on the HS-responsive mesoporous CuCl(OH)-loaded hypoxic prodrug tirapazamine (TPZ), in which the outer layer was coated with hyaluronic acid (HA) to form TPZ@CuCl(OH)-HA (TCuH) nanoparticles (NPs), demonstrated a synergistic antitumor effect through combining the HS-driven cuproptosis and mild photothermal therapy.

Oxfendazole Induces Apoptosis in Ovarian Cancer Cells by Activating JNK/MAPK Pathway and Inducing Reactive Oxygen Species Generation.

Ovarian cancer (OC) is one of the most common and high mortality type of cancer among women worldwide. The majority of patients with OC respond to chemotherapy initially; however, most of them become resistant to chemotherapy and results in a high level of treatment failure in OC. Therefore, novel agents for the treatment of OC are urgently required.

Improves Lipid Metabolism Disorder and Insulin Resistance in Type 2 Diabetic Mice.

Additional effective therapeutic strategies for Type 2 diabetes (T2D) patients are urgently needed Gut microbiota plays an important role in T2D development and is a promising treatment strategy for T2D patients. Faecalibacterium prausnitzii () is regarded as one of the most important bacterial indicators for a healthy gut, but the mechanisms of its anti-diabetic properties are still unclear. The abundance of in feces of patients with T2D was detected by using qPCR.

KCNH3 Predicts Poor Prognosis and Promotes Progression in Ovarian Cancer.

Background: Ovarian cancer (OC) is one of the most common causes of cancer-related death among women; accordingly, new biomarkers of OC are urgently needed. Potassium voltage-gated channel sub-family H member 3 (KCNH3) is a voltage-gated potassium channel member involved in cognitive function and diabetes. Here, we aimed to elucidate the role and potential molecular mechanisms of KCNH3 in OC.
