Neuropilin-1 (NRP-1) is a non-tyrosine kinase receptor for vascular endothelial growth factor (VEGF) that was recently found to play a role in tumor functions. Previous studies demonstrated that NRP-1 was overexpressed in a number of human tumors, including glioblastoma (GBM). However, the role of NRP-1 in glioma progression has yet to be adequately elucidated. Thus, we examined the expression ...

Signal processing and integration is critical in physiology, as it is in disease conditions. Conversion of extracellular signals into appropriate biological responses by cell membrane receptors, and subsequent extinction of signaling events is critical to cellular hemostasis. Defective trafficking, internalization or degrardation of transmembrane receptors (TMRs) result in perturbed activation ...

Neuropilin-1 (NRP-1) is a type 1 membrane protein that binds the axon guidance factors belonging to the class-3 semaforin family. In endothelial cells, NRP-1 serves as a co-receptor for vascular endothelial growth factor (VEGF) and regulates VEGF receptor 2 (VEGFR-2)– dependent angiogenesis. Although genetargeting studies documenting embryonic lethality in NRP-1 null mice have demonstrated a cr...

OBJECTIVE To investigate soluble neuropilin-1 (sNRP-1) in circulating and NRP-1 protein in cervical tissues from patients with cervical cancer or cervical intraepithelial neoplasia (CIN). METHODS sNRP-1 was measured in 64 preoperative patients and 20 controls. NRP-1 protein in cervical tissue was detected in 56 patients and 20 controls. RESULTS Both sNRP-1 and NRP-1 proteins were correlated...

Metastasis, the leading cause of cancer death, requires tumor cell intravasation, migration through the bloodstream, arrest within capillaries, and extravasation to invade distant tissues. Few mechanistic details have been reported thus far regarding the extravasation process or re-entry of circulating tumor cells at metastatic sites. Here, we show that neuropilin-2 (NRP-2), a multifunctional n...

Protein immobilization plays a key role in the development of all protein-based biosensors in order to achieve good performances. Conventional techniques such as physical adsorption or randomly chemical coupling usually lead to low activity and reproducibility. Therefore there is an essential need for uniformly oriented, covalent immobilization approaches. In this study, the nanobody targeting ...

The adipocyte-derived cytokine leptin acts as a metabolic switch, connecting the body's metabolism to high-energy consuming processes such as reproduction and immune responses. Accumulating evidence suggests that leptin plays a role in human pathologies, such as autoimmune diseases and cancer, thus providing a rationale for the development of leptin antagonists. In the present study, we generat...

objective: the objective of this study is to develop and assess targeted pamam-peg nanocarrier with anti-tag72 nanobody for t-bid gene coding construct delivery into the human colonic adenocarcinoma cells. materials and methods: nanobody (nb) coding sequence was subcloned into psj expression vector for large-scale production and then nb was purified by ni++ affinity chromatography. sds-page an...
