The Nerve Growth Factor Precursor Prongf Exhibits Neurotrophic Activity Similar to That of Mature Nerve Growth Factor
Nerve growth factor (NGF) promotes neuronal survival and differentiation and stimulates neurite outgrowth. NGF is synthesized as a precursor, proNGF, which undergoes post-translational processing to generate mature $-NGF. It has been assumed that, in vivo, NGF is largely processed into the mature form and that mature NGF accounts for the biological activity. However, we recently showed that pro...
متن کاملThe nerve growth factor precursor proNGF exhibits neurotrophic activity but is less active than mature nerve growth factor.
Nerve growth factor (NGF) promotes neuronal survival and differentiation and stimulates neurite outgrowth. NGF is synthesized as a precursor, proNGF, which undergoes post-translational processing to generate mature beta-NGF. It has been assumed that, in vivo, NGF is largely processed into the mature form and that mature NGF accounts for the biological activity. However, we recently showed that ...
متن کاملNerve growth factor in human semen: Effect of nerve growth factor on the normozoospermic men during cryopreservation process
Objective(s):Althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. Adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm DNA fragmentation and infertility. The post-thaw survival of sperm...
متن کاملBiological activity of nerve growth factor precursor is dependent upon relative levels of its receptors.
Nerve growth factor (NGF) is produced as a precursor called pro-nerve growth factor (proNGF), which is secreted by many tissues and is the predominant form of NGF in the central nervous system. In Alzheimer disease brain, cholinergic neurons degenerate and can no longer transport NGF as efficiently, leading to an increase in untransported NGF in the target tissue. The protein that accumulates i...
متن کاملEffects of Nerve Growth Factor, Insulin- Like Growth Factor-I and Collagen Gel on Peripheral Nerve Channel: Sensory, Functional and Regeneration Through Piezoelectric Electrophysiologicalal Study
Purpose: The limited availability of donor sites for nerve grafts continues to stimulate research toward finding suitable alternatives. Material and Methods: In the following study, the effects of direct administration of Nerve Growth Factor (NGF), Insulin - Like Growth Factor - I (IGF-I) , or / and collagen gel into Polyvinylidene Fluride (PVDF) gap was tested in a rat sciatic nerve model. A ...
