摘要:
Disclosed herein are methods and compositions for modulating the levels and/or activity of S-nitrosoglutathione reductase (GSNOR) in vivo or in vitro. Specifically disclosed are GSNOR deletion constructs, host cells and non-human mammals comprising GSNOR deletions, and methods of screening employing GSNOR deletion mutants. Also specifically disclosed are reagents and procedures for measuring, monitoring, or altering GSNOR levels or activity (as well as nitric oxide and S-nitrosothiol levels) in connection with various medical conditions.
摘要:
Patients needing NO donor therapy or inhibition of pathologically proliferating cells or increased NO bioactivity are treated with a therapeutically effective amount of an inhibitor of glutathione-dependent formaldehyde dehydrogenase.
摘要:
The presently disclosed subject matter provides methods for increasing perfusion in hypoxic regions of tissues in subjects. Also provided are methods for treating diseases and/or disorders associated with hypoxia in subjects, methods for increasing sensitivity of tumors to radiation and/or chemotherapy treatments, methods for delaying tumor growth in subjects, and methods for inhibiting tumor blood vessel growth in subjects. In some embodiments, the presently disclosed methods involve administering to subjects in need thereof a first composition selected from the group consisting of a nitrosylated hemoglobin and an agent that induces nitrosylation of endogenous hemoglobin in the subject and a second composition comprising a hyperoxic gas. In some embodiments, the presently disclosed methods also include treating a tumor with radiation therapy, chemotherapy, photodynamic therapy, immunotherapy, or combinations thereof. Also provided are inhalable gases that can be employed in the presently disclosed methods.

摘要:
Genomic actions and/or proteomic interactions for pathophysiological processes and for physiological processes are determined at associated redox state conditions. Protein interactions are correlated with oxygen tensions. Identification of markers for disease including epitopes is effected in the presence of simulated redox state perturbations. Screening for previously unknown receptors and activating ligands is carried out in the presence of alteration of redox state.
摘要:
The present invention provides compositions comprising a gas and a gastrointestinal smooth muscle relaxing agent comprising ethyl nitrite in a therapeutically effective amount. The present invention also provides methods of relaxing gastrointestinal smooth muscle, alleviating contraction or spasm of gastrointestinal smooth muscle to facilitate a diagnostic medical procedure and treating or preventing a gastrointestinal disorder using the compositions of the invention.
摘要:
Amount of combined nitric oxide or nitric oxide present as iron nitrosyls in a blood sample is determined by directing a low power electromagnetic radiation beam at a blood sample to liberate nitric oxide gas, dissolving the liberated nitric oxide gas and electrochemically detecting amount of dissolved nitric oxide gas.
摘要:
Nitrosylhemoglobin can be produced by introducing gaseous NO into an aqueous solution of hemoglobin. It has been demonstrated that nitrosylhemoglobin in aqueous solution can be converted to SNO-hemoglobin upon introduction of oxygen to the solution, as is postulated to occur in the lungs. Nitrosylhemoglobin can be used in methods to produce the physiological effects of NO, for example, to reduce vasoconstriction and to inhibit platelet aggregation.
摘要:
S-nitrosohemoglobin can liberate NO by transfer to a low molecular weight thiol in the circulatory system, allowing the delivery of NO to the tissues. The effect of administering isolated S-nitrosohemoglobin and low molecular weight thiol to a mammal is to increase delivery of oxygen and NO.
