The road to clinical success is littered with great ideas that have come a cropper along the way, including two other RNA-based therapies, antisense and ribozymes, both of which showed promise at the bench but have largely stumbled before reaching the bedside.
“There was a lot of clinical naïveté” in the early days of antisense and ribozymes, according to Nassim Usman, Vice President for Research and Development at Sirna Therapeutics in Boulder, Colorado.
In vivo studies have supported the conclusion that CBP/p300 are components of the hormonal-regulation of transcription in fibroblasts isolated from a p300-/- mouse; and loss of the p300 gene severely affects retinoic acid (RA)-dependent transcription [ 91 ] . In a separate study using hammerhead ribozymes that specifically cleave CBP or p300 mRNA, Kawasaki et al [ 92 ] reported that reduced cellular CBP or p300 levels resulted in compromised expression of endogenous RA-inducible genes such as p21/Waf1 and p27 cdk inhibitors.
Growing disillusionment with antisense and ribozymes coincided with the discovery of RNAi and the realization that it was a far more potent way to silence gene expression.
High levels of OPN in breast tumor cell lines appear to correlate with a more aggressive in vivo phenotype [ 2 20 ] . Transfection of OPN expression constructs into cells producing noninvasive mammary epithelial tumors has been reported to convert them to a malignant phenotype [ 8 21 ] . Furthermore, transfection of antisense OPN constructs or OPN-targeting ribozymes into transformed tumorigenic cells can result in impaired anchorage-independent growth, as well as in diminished tumor-forming ability in vivo [ 22 23 ] . OPN is also typically overexpressed in human tumors, including breast cancer [ 15 24 ] . However, the source of OPN in primary breast tumors was originally thought to be infiltrating macrophages rather than tumor cells themselves [ 15 ] .
