Progesterone and 1,25-dihydroxyvitamin D₃ inhibit endometrial cancer cell growth by upregulating semaphorin 3B and semaphorin 3F.
Class 3 semaphorins (SEMA), SEMA3B and SEMA3F, are secreted proteins that regulate angiogenesis, tumor growth, and metastasis by binding to their transmembrane receptor complex consisting of plexins and neuropilins (NP). Expression of SEMAs and their receptors was assessed in tissue microarrays by immunohistochemistry. SEMA3B, SEMA3F, and plexin A3 were expressed strongly in normal endometrial ...
متن کاملHormonal regulation and distinct functions of semaphorin-3B and semaphorin-3F in ovarian cancer.
Semaphorins comprise a family of molecules that influence neuronal growth and guidance. Class-3 semaphorins, semaphorin-3B (SEMA3B) and semaphorin-3F (SEMA3F), illustrate their effects by forming a complex with neuropilins (NP-1 or NP-2) and plexins. We examined the status and regulation of semaphorins and their receptors in human ovarian cancer cells. A significantly reduced expression of SEMA...
متن کاملSemaphorin 3A and 3F: key players in myelin repair in multiple sclerosis?
The presence of demyelinated plaques in the central nervous system is the hallmark of multiple sclerosis (MS). Some plaques remyelinate but others do not, leaving permanent damage. The reasons for this failure of repair are many, but one possible reason is the lack of migration of oligodendrocyte precursor cells to the lesion. The guidance molecules Semaphorin 3A and 3F, already known to direct...
متن کاملSemaphorin 3A elevates endothelial cell permeability through PP2A inactivation.
VE-cadherin-mediated cell-cell junction weakening increases paracellular permeability in response to both angiogenic and inflammatory stimuli. Although Semaphorin 3A has emerged as one of the few known anti-angiogenic factors to exhibit pro-permeability activity, little is known about how it triggers vascular leakage. Here we report that Semaphorin 3A induced VE-cadherin serine phosphorylation ...
متن کاملEndothelial cell-derived semaphorin 3A inhibits filopodia formation by blood vascular tip cells.
Vascular endothelial growth factor (VEGF)-A is a well-known major chemoattractant driver of angiogenesis--the formation of new blood vessels from pre-existing ones. However, the repellent factors that fine-tune this angiogenic process remain poorly characterized. We investigated the expression and functional role of endothelial cell-derived semaphorin 3A (Sema3A) in retinal angiogenesis, using ...
