Secretoneurin, rat
Based on 1 Customer Validation
Secretoneurin, rat is a 33-amino acid neuropeptide produced by proteolytic processing of chromogranin II, widely distributed in the central and peripheral nervous systems, and its release is calcium-dependent. Secretoneurin, rat modulates the activities of caspase-3, caspase-1, the NLRP3 inflammasome, IGF-1R, VEGFR1, VEGFR2, FGFR3, AMPK, ERK1/2/MAPK, and Jak2/Stat3 pathways. Secretoneurin, rat regulates neuronal apoptosis, synaptic structure, inflammation, neurogenesis, angiogenesis, oxidative stress, cardiomyocyte hypertrophy, dopamine release, and cell migration and proliferation. Secretoneurin, rat is used in studies of global cerebral ischemia, myocardial infarction, stroke, and cardiac hypertrophy.

In Vitro
Secretoneurin, rat (1-100 ng/mL) induces dose-dependent chemotactic migration of human coronary artery endothelial cells, with a maximum relative chemotactic index of 2.4 at 100 ng/mL[2].
Secretoneurin, rat (100 pg/mL-100 ng/mL; 6 hours) induces capillary-like tube formation in human coronary artery endothelial cells, with a maximum relative tube formation of 2.2 at 10 ng/mL after 6 hours[2].
Secretoneurin, rat (100 ng/mL; 5-240 minutes) activates both ERK (starting at 20 minutes) and Akt (starting at 40 minutes) in human coronary artery endothelial cells, with activation lasting up to 4 hours[2].
Secretoneurin, rat (100 ng/mL; 40-120 minutes) stimulates phosphorylation of VEGFR1, VEGFR2, FGFR3, and IGF-1R in human coronary artery endothelial cells[2].
Secretoneurin, rat (100 ng/mL) stimulates proliferation of human coronary artery endothelial cells to a relative level of 1.42, dependent on both VEGFR2 and MAPK pathway activity[2].
Secretoneurin, rat (100 ng/mL) increases both the binding capacity and affinity of VEGF to human coronary artery endothelial cells in a heparan sulfate proteoglycan-dependent manner[2].
Secretoneurin, rat (10-100 ng/mL) increases VEGF binding to Heparin (HY-17567) in a cell-free system[2].
Secretoneurin, rat increases VEGF binding to its coreceptor neuropilin-1 in a cell-free system[2].

Secretoneurin, rat (1 μg/L; pretreatment before 2 h OGD) reduced caspase‑3 activity in primary cortical cells from embryonic Sprague‑Dawley rats subjected to oxygen‑glucose deprivation (OGD)[3].
Secretoneurin, rat (1 μg/L; pretreatment before 2 h OGD) decreased the number of activated caspase‑3‑positive cells in primary cortical cells from embryonic Sprague‑Dawley rats subjected to oxygen‑glucose deprivation (OGD)[3].
Secretoneurin, rat (1 μg/L; 12 h pretreatment before OGD) prevented oxygen‑glucose deprivation (OGD)‑induced down‑regulation of the anti‑apoptotic protein Bcl‑2 in primary cortical cells from embryonic Sprague‑Dawley rats.
Secretoneurin, rat (1 μg/L; 20 min pretreatment before 4 h OGD) pre‑treated primary cortical cells of embryonic Sprague‑Dawley rats 20 min before 4‑h OGD decreased LDH release and maintained MAP‑2‑positive neuron density, while post‑OGD treatment showed no efficacy[3].
Secretoneurin, rat (0.01‑10 μg/L; 0.5‑12 h) activated the Jak2/Stat3 pathway in a time‑ and dose‑dependent manner in primary cortical cells derived from embryonic Sprague‑Dawley rats, with each phosphorylated protein (p‑Stat3 and p‑Jak2) showing an approximately 2‑fold maximum increase relative to actin[3].
Secretoneurin, rat (1 μg/L; 1-28 days)‑mediated protection of MAP‑2‑positive neurons under OGD conditions in primary cortical cells from embryonic Sprague‑Dawley rats was abolished by the Jak2 inhibitor AG490 (HY‑12000)[3].
Secretoneurin, rat is widely distributed in postmortem human eye tissues, with the highest concentration in the choroid followed by the retina, iris/ciliary body, sclera, and cornea[5].
Secretoneurin, rat-immunoreactive nerve fibers are widely distributed throughout the anterior segment and choroid of postmortem human eyes, innervating the cornea, limbus, trabecular meshwork, iris, ciliary body, and choroid[5].
