There are two types of cyclic AMP (cAMP)-dependent protein kinase (PKA), type I (PKA-I) and type II (PKA-II), which share a common catalytic (C) subunit but contain distinct regulatory (R) subunits, RI versus RII, respectively. Evidence suggests that increased expression of PKA-I and its regulatory subunit (RIalpha) correlates with tumorigenesis and tumor growth. We investigated the effect of sequence-specific inhibition of RIalpha gene expression at the initial phase of 7,12-dimethylbenz(alphaa)anthracene (DMBA)-induced mammary carcinogenesis.
