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 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 lung 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].
