Negative Regulation of Semaphorin-3A Expression in Peripheral Blood Mononuclear Cells Using MicroRNA-497-5p
Background: Semaphorin-3A (Sema3A), as a secreted semaphorin, is an immune modulator molecule participating in the pathogenesis of autoimmune diseases. MicroRNAs (miRNAs) modulate the target-gene expression at the post-transcriptional level. It has been proposed that miRNAs may be crucial to the modulation of the function of semaphorins. Previous findings have proven that miR-497-5p is upregula...
متن کاملLentiviral Mediated Expression of Soluble Neuropilin 1 Inhibits Semaphorin 3A-mediated Collapse Activity in Vitro
Introduction: Semaphorin 3A (Sema 3A) is a secreted protein, which plays an integral part in developing the nervous system. It has collapse activity on the growth cone of dorsal root ganglia. After the development of the nervous system, Sema 3A expression decreases. Neuropilin 1 is a membrane receptor of Sema 3A. When semaphorin binds to neuropilin 1, the recruitment of oligodendrocyte precurso...
متن کاملExpression of Semaphorin 3A and Neuropilin 1 in Asthma
Neuropilin 1 (NP1) is a part of essential receptor complexes mediating both semaphorin3A (SEMA3A) and vascular endothelial growth factor (VEGF) which is one of important mediators involved in the pathogenesis of asthma. Therefore, it is possible that SEMA3A plays a role in the pathogenesis of asthma through attenuation of VEGF-mediated effects. In the present study, we aimed to evaluate express...
متن کاملSignificance of semaphorin-3A and MMP-14 protein expression in non-small cell lung cancer
Semaphorin-3A is a chemorepellent guidance protein that is crucial in regulating the tumor microenvironment. MMP-14, a membrane-anchored matrix metalloproteinase, is closely associated with extracellular matrix (ECM) remodeling and cell migration in the progression of cancer metastasis. In the present study, the correlation between the expression levels of semaphorin-3A and MMP-14, and their su...
متن کاملExpression of semaphorin 3A and neuropilin 1 with clinicopathological features and survival in human tongue cancer
OBJECTIVE To investigate the association between semaphorin 3A (SEMA 3A) and its receptor neuropilin 1 (NRP1) and the clinicopathologic characteristics of patients with tongue cancer. STUDY DESIGN Forty-three tongue squamous cell carcinoma specimens were included. Immunohistochemical staining of SEMA3A and NRP1 was performed on 15 normal tongue epithelium specimens and the 43 tumour specimens...
