The ability of skin to support long lasting expression of genes delivered with a particle-mediated system was evaluated in rabbits inoculated with cottontail rabbit papillomavirus (CRPV) DNA. The optimal delivery force for maximal gene expression in rabbit skin was determined in transient beta-galactosidase assays. Forty-five sites in four rabbits were then inoculated at 350-400 p.s.i. with CRPV DNA. All sites (100%) formed papillomas with multiple papillomas at most sites. These results support the feasibility of using a particle-mediated delivery system for gene therapy and suggest that some papillomavirus features, such an origin of replication, may be well suited for use in vectors to target long term expression to skin.
在接种了棉尾兔乳头瘤病毒(CRPV)DNA的兔子中,评估了皮肤支持通过粒子介导系统递送的基因长期表达的能力。通过瞬时β-半乳糖苷酶测定法确定了兔皮肤中实现最大基因表达的最佳递送力。然后,在350-400磅力/平方英寸的压力下,对4只兔子的45个部位接种CRPV DNA。所有部位(100%)均形成了乳头瘤,大多数部位有多个乳头瘤。这些结果支持了使用粒子介导递送系统进行基因治疗的可行性,并表明某些乳头瘤病毒特征,如复制起点,可能非常适合用于载体,以实现皮肤的长期靶向表达。
