The properties of NIH 3T3 cells transfected with Shope fibroma virus (SFV) DNA were investigated. Six focus-derived cell lines were established that display the following properties: a) They all contained SFV DNA sequences at early passages, b) five of them also expressed SFV RNA at early passages a

โฆ Synopsis
This study reports high incidence tumourigenic activity of the pSV2neo plasmid demonstrated by transfection of NIH 3T3 cells. The plasmid is frequently used as a dominant selectable marker for confirming successful gene transfection, and the findings indicate a need for caution in interpretation and design of assays for oncogenes which use co-transfection and subsequent selection with neomycin.

The single-copy fibroblast growth factor 2 (FGF-2) gene encodes four coexpressed isoforms of different molecular masses. The 18-kDa FGF-2 is primarily localized in the cytoplasm, whereas the higher molecular mass isoforms (HMW FGF-2) localize to the nucleus and nucleolus. The overexpression of eithe
