Class 3 semaphorins in cardiovascular development
Secreted class 3 semaphorins (Sema3), which signal through holoreceptor complexes that are formed by different subunits, such as neuropilins (Nrps), proteoglycans, and plexins, were initially characterized as fundamental regulators of axon guidance during embryogenesis. Subsequently, Sema3A, Sema3C, Sema3D, and Sema3E were discovered to play crucial roles in cardiovascular development, mainly a...
متن کاملRole of class 3 semaphorins and their receptors in tumor growth and angiogenesis.
Class 3 semaphorins (SEMA3) were first identified as glycoproteins that negatively mediate neuronal guidance by binding to neuropilin and repelling neurons away from the source of SEMA3. However, studies have shown that SEMA3s are also secreted by other cell types, including tumor cells, where they play an inhibitory role in tumor growth and angiogenesis (specifically SEMA3B and SEMA3F). SEMA3s...
متن کاملClass 3 semaphorins expression and association with innervation and angiogenesis within the degenerate human intervertebral disc
Nerve and blood vessel ingrowth during intervertebral disc degeneration, is thought to be a major cause of low back pain, however the regulation of this process is poorly understood. Here, we investigated the expression and regulation of a subclass of axonal guidance molecules known as the class 3 semaphorins, and their receptors; plexins and neuropilins within human NP tissue and their regulat...
متن کاملExpression of class 3 semaphorins and neuropilin receptors in the developing mouse tooth
The semaphorins are a large family of secreted or cell-bound signals needed for the development of the nervous system. We compared mRNA expression of class 3 semaphorins (Sema3A, 3B, 3C and 3F) and their two receptors (Neuropilin-1 and -2) in the embryonic mouse first molar tooth germ (E10-18) by radioactive in situ hybridization. All genes showed distinct developmentally regulated expression p...
متن کاملClass 3 semaphorins and their receptors in physiological and pathological angiogenesis.
Class 3 semaphorins (Sema3) are a family of secreted proteins that were originally identified as axon guidance factors mediating their signal transduction by forming complexes with neuropilins and plexins. However, the wide expression pattern of Sema3 suggested additional functions other than those associated with the nervous system, and indeed many studies have now indicated that Sema3 protein...
