A single-injection protein kinase A-directed antisense treatment to inhibit tumour growth

Abstract
Expression of the RIα subunit of cAMP-dependent protein kinase type I is enhanced in human cancer cell lines, in primary tumours, in cells after transformation and in cells upon stimulation of growth. We have investigated the effect of sequence-specific inhibition of RIα gene expression on in vivo tumour growth. We report that single injection RIα antisense treatment results in a reduction in RIα expression and inhibition of tumour growth. Tumour cells behaved like untransformed cells by making less protein kinase type I. The RIα antisense, which produces a biochemical imprint for growth control, requires infrequent dosing to halt neoplastic growth in vivo.
