    The protein expression of the biomarkers of JAK-STAT signaling pathway. The expression of TNF-α, IFN-β, IL-6 and MCP-1 is all upregulated and IL-4 expression are downregulated in the group treated with miR-142-5p versus the NC group, and it could be rescued by Colivelin.

    Description

    Colivelin is a brain penetrant neuroprotective peptide and a potent activator of STAT3, suppresses neuronal death by activating STAT3 in vitro[1]. Colivelin exhibits long-term beneficial effects against neurotoxicity, Aβ deposition, neuronal apoptosis, and synaptic plasticity deficits in neurodegenerative disease[2]. Colivelin has the potential for the treatment of alzheimer's disease and ischemic brain injury[1]

    In Vitro

    Colivelin completely suppresses death induced by overexpressed FAD-causative genes and Aβ1-43 at a concentration of 100 fm, and keep its neuroprotective action at or above the levels of 1 nm[1].
    Colivelin-induced neuroprotection occurs via two neuroprotective pathways: one mediated by Ca2+/calmodulin-dependent protein kinase IV, triggered by ADNF, and one mediated by signal transducer and activator of transcription 3, triggered by HN[1].
    Colivelin reverses caspase3, Bax and Bcl-2 expressions in HT22 cells medaited by rmMFG-E8 in the co-cultured cells under OGD condition[4].
    Colivelin (50 µg/mL, 4 hours) significantly increases the p-STAT3 protein levels in BV-2 cells[4].

    Western Blot Analysis[4]

    Cell Line: BV-2 cells.
    Concentration: 50 µg/mL.
    Incubation Time: 4 hours.
    Result: Increased p-STAT3 levels.

    Cell Viability Assay[5]

    Cell Line: KYSE70 and TE8 cells.
    Concentration: 0.5 μM.
    Incubation Time: 1 hour (followed by CYT-Rx20 treatment)
    Result: Sgnificantly suppressed the viability in KYSE70 and TE8 cells.
    In Vivo

    Colivelin (intracerebroventricular administration; 10 pmol/3 μl; 3 weeks) suppresses impairment in spatial working memory induced by repetitive intracerebroventricular injection of Aβ25-35 or Aβ1-42, in addition, it antagonizes neuronal loss in the CA1 region of hippocampus induced by hippocampal injection of Aβ1-42[1].
    Colivelin (intraperitoneal administration; 1.4, 7, or 35 nM/0.21 mL; on the Y-maze testday) suppresses memory impairment caused by 3-quinuclidinyl benzilateand restricts functional memory deficit[1].
    Colivelin (intraperitoneal injection; 1 mg/kg; 14 days) results in improved motor and cognitive function with time by performance of mNSS, rotarod, and corner turning test.It also reduces lesion volume and improves neurological deficits after MCAO[3].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
