“…pDARP-PE40 plasmid, containing encoding sequences of the targeted module DARPin_9-29 and a cytotoxic module based on PE40 fragment of Pseudomonas exotoxin A in one reading frame under the control of inducible promoter T7 has been previously created by us [17]. Encoding sequence of the fluorescent protein mCherry was obtained by treating pIG6-4D5scFv-mCherry with AscI restriction endonuclease [18] and ligated with plasmid pDARP-PE40 [17], pretreated with the same endonuclease. Plasmid pDARP-mCherry-PE40 containing in one reading frame under the control of inducible promoter T7 encoding sequences of the targeted module DARPin_9-29, fluorescent protein mCherry, and PE40 fragment of Pseudomonas exotoxin A (Figure 1 (a)) was obtained.…”

“…They do not contain cysteine; hence, they are resistant to protease and can be expressed in bacteria. Because of their small size, penetrate better in tumour cells . A recombinant toxin fused DARPins was used against HER2 + Breast cancer xenograft mouse.…”

“…Ранее нами были разработаны направленные токсины DARPin-PE40 [4] и DARPin-LoPE [5], селективно уничтожающие клетки с повышенным содержанием онкоспецифического рецептора ERBB2. Этот рецептор часто используется при разработке различных направленных противоопухолевых агентов [6].…”
