The invention relates to the use of a skin permeating compound such as phloretin for controlling transgene expression under control of the Pseudomonas putida DOT-T1 E-derived bacterial repressor TtgR, to a vector comprising the genetic code for the repressor TtgR fused to a transactivation or a transrepressor domain, to a vector comprising a TtgR-specific operator sequence (OTtgR), a promoter and a polynucleotide coding for an endogenous or exogenous protein, and to a mammalian cell transiently or constitutively transfected with the mentioned vectors, and to mammals comprising such cells in nano- or microcontainers.
本发明涉及一种皮肤渗透性化合物(如phloretin)用于控制由假单胞杆菌 DOT-T1 E 衍生的细菌抑制因子 TtgR 控制的转
基因表达,涉及一种载体,该载体包含与反式激活结构域或反式抑制结构域融合的抑制因子 TtgR 的遗传密码、由 TtgR 特异性操作序列 (OTtgR)、启动子和编码内源或外源蛋白质的多核苷酸组成的载体,以及用上述载体瞬时或组成型转染的哺乳动物细胞,以及由纳米或微型容器中的此类细胞组成的哺乳动物。
