Nerve growth factor from cobra venom.
The chemical and biological properties of the nerve growth factor isolated from Naja naja venom are described. The nerve growth promoting activity appears to be distinct from the most commonly known enzymes and toxins present in the venom. The purified nerve growth factor from cobra venom has properties remarkably similar to those of the nerve growth factor isolated from mouse submaxillary glan...
متن کاملCobra Venom Factor and Ketoprofen Abolish the Antitumor Effect of Nerve Growth Factor from Cobra Venom
We showed recently that nerve growth factor (NGF) from cobra venom inhibited the growth of Ehrlich ascites carcinoma (EAC) inoculated subcutaneously in mice. Here, we studied the influence of anti-complementary cobra venom factor (CVF) and the non-steroidal anti-inflammatory drug ketoprofen on the antitumor NGF effect, as well as on NGF-induced changes in EAC histological patterns, the activity...
متن کاملNerve Growth Factor from Cobra Venom Inhibits the Growth of Ehrlich Tumor in Mice
The effects of nerve growth factor (NGF) from cobra venom (cvNGF) on growth of Ehrlich ascites carcinoma (EAC) cells inoculated subcutaneously in mice have been studied. The carcinoma growth slows down, but does not stop, during a course of cvNGF injections and restores after the course has been discontinued. The maximal anti-tumor effect has been observed at a dose of 8 nmoles cvNGF/kg body we...
متن کاملNerve growth factor from Chinese cobra venom stimulates chondrogenic differentiation of mesenchymal stem cells
Growth factors such as transforming growth factor beta1 (TGF-β1), have critical roles in the regulation of the chondrogenic differentiation of mesenchymal stem cells (MSCs), which promote cartilage repair. However, the clinical applications of the traditional growth factors are limited by their high cost, functional heterogeneity and unpredictable effects, such as cyst formation. It may be adva...
متن کاملEffect of Cobra Venom Factor Treatment
Squirrel monkeys were significantly depleted of complement by a nontoxic protein constituent of cobra venom, and the influence of cobra factor (CoF) treatment on the course of Escherichia coli bacteremia was studied. Striking neutropenia occurred rapidly in control animals while the rate of occurrence of neutropenia was 20 to 30 times slower in the CoF-treated animals, suggesting that the E. co...
