Background: Ischemia reperfusion (IR) injury leads to activation of dynamin-re- lated protein (Drp-1), causing mitochondrial fission and generation of reactive oxy- gen species (ROS), but the molecular mechanisms that activate Drp-1 are not known. The …

Hypertensive cardiac remodeling is a constellation of abnormalities that includes cardiomyocyte hypertrophy and death and tissue fibrosis. Adenosine is a long-known vasodilator, through interacting with its four cell surface receptor subtypes in …

Chelating Cu from tumors has been verified as an effective and promising strategy for cancer therapy through antiangiogenesis. However, systematic removal Cu by injecting with Cu chelators will result unavoidable side effects, since Cu is indispensable to …

More than a quarter of a million individuals in the US live with spinal cord injury (SCI). SCI disrupts neural circuitry to vital organs in the body. Despite severe incidences of long-term peripheral complications from SCI, the cardio-metabolic …

Angiotensin-converting enzyme 2 (ACE2) is critically involved in cardiovascular physiology and pathology, and is currently clinically evaluated to treat acute lung failure. Here we show that the B38-CAP, a carboxypeptidase derived from Paenibacillus sp. …

Hypoxia inactivates hypoxia-inducible factor (HIF) prolyl 4-hydroxylases (HIF-P4Hs), which stabilize HIF and upregulate genes to restore tissue oxygenation. HIF-P4Hs can also be inhibited by small molecules studied in clinical trials for renal anemia. …

Malignant proliferation of tumor cells induces abnormal tissue microenvironments, leading to therapeutic resistance and poor therapeutic outcome. In this paper, manganese dioxide (MnO2) nanoshells are coated on a porphyrinic metal–organic framework of …

Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease exhibiting the poorest prognosis among solid tumors. The efficacy of conventional therapies has been hindered largely due to the insufficient chemotherapeutic delivery to the dense …

Group 2 innate lymphoid cells (ILC2s) regulate inflammation and immunity in mammalian tissues1,2. Although ILC2s are found in cancers of these tissues3, their roles in cancer immunity and immunotherapy are unclear. Here we show that ILC2s infiltrate …

Sepsis-induced myocardial dysfunction is a critical cause of high mortality among patients with sepsis. Previously, insulin has been suggested to protect against lethal endotoxemia, while uncoupling protein 2 (UCP2) has been reported to exert beneficial …
