Origin of Peptide | Derived from the membrane-proximal ligand-binding domain of human TGF-β1 type III receptor (β-glycan) | |
Nature of Peptide/Cargo | Interferes with TGF-β1 binding to its cellular receptors on Mv1Lu cells. Potent in vivo anti-fibrotic activity in the liver of rats receiving CCl4 | |
Mechanism | P144 prevented TGF-β1-dependent inhibition of Mv1Lu cell proliferation and, in cultured fibroblasts, it induced a concentration-dependent decrease on TGF-β1-dependent stimulation of a reporter gene under the control of human α2(I) collagen promoter | |
Cargo Sequence/Structure | None | |
Name of cargo | Not applicable | |
Assay | Sircol Collagen Assay kit, histological and immunohistochemical studies | |
Enhancer | Skin sclerosis induced by bleomycin | |
Properties of enhancer | Not mentioned | |
Concentration | 10 g dimethicone, 40 g liquid paraffin, 0.1 g chlorocresol, 0.5 g cetrimide, and 5 g ketostearic alcohol. This mixture was warmed to 70ͦC and emulsified with 44.28 of water plus 0.010 g of P144 previously dissolved in 100 µL of dimethyl sulfoxide | |
Incubation time | Daily application of 100µl of the P144 peptide lipogel preparation onto the shaved skin of the P144 peptide lipogel preparation for 4 weeks | |
Tissue permeability (value with units) | Dermal thickness: Bleomycin treated-180%, Bleomycin plus P144 lipogel emulsion-120%, Bleomycin plus vehicle-200%. Soluble collagen: Bleomycin treated-215%, Bleomycin plus P144 lipogel emulsion-150%, Bleomycin plus vehicle-220%. Data represent mean±SD of 10 mice per group, and the values of PBS-treated mice are set to 100%. | |
Tissue Sample | Shaved skin area of female C3H mice | |
