Description of SN50

SN50, the NF-κB cell-permeable inhibitory peptide. It is comprised of the hydrophilic region of the signal peptide of Kaposi fibroblast growth factor as a membrane translocating motif and a nuclear localization sequence derived from the p50 subunit of NF-κB[1].

SN50(20 µg/ml; 12 hs) could induce the microglia differentiation into M2 type through the NF-κB pathway. The SN50-induced microglia can protect neurons from hypoxic injury[2]. SN50 (25 µg/ml; 24 hs) could induce robust differentiation of GSCs, and the differentiated daughter cells lose the neuroglobular motility, invasiveness, and treatment insensitivity tumorigenicity of tumor stem cells[4].

SN50(100µl,10,30,60µg/ml; i.p.;1h) attenuated alveolar hypercoagulation and fibrinolysis inhibition in ARDS via inhibition of NF-κB p65 translocation[5].SN50(1µM) protected against LPS-induced lung injury in isolated rat lungs by inhibiting NF-κB nuclear translocation[6]. Topical SN50 (10µM; 12 days) suppressed nuclear factor-κB activation in local cells and reduced the incidence of epithelial defects/ulceration in C57BL/6 mice healing corneas[7].

Protocol of SN50

Cell experiment [1]:

Cell lines

Glioma stem-like cells GSC11 and GSC23 cells

Preparation Method

Cells were cultured in medium containing 2% B-27, 20 ng/mL EGF, and 20 ng/mL β-FGF in the presence or absence of SN50 (25 µg/mL) for twenty-four hours.

Reaction Conditions

25 µg/ml; 24 hours

Applications

SN50 can induce GSC differentiation.

Animal experiment [2]:

Animal models

Male Balb/c mice(8-12 weeks)

Preparation Method

Mice was made by 50 µl of lipopolysaccharide (LPS) (4 mg/ml) inhalation. Mice were intraperitoneally injected with different does of SN50 1 h before LPS inhalation.

Dosage form

100µl,10,30,60µg/ml; i.p.;1h

Applications

SN50 inhibited expressions of TF and PAI-1 in mRNA and in protein levels in LPS-induced acute respiratory distress syndrome (ARDS) mice.
