title: Angiotensin stimulates the expression of interferon-inducible genes in H295R cells.
abstract: Angiotensin-II (A-II) induces proliferation of zona glomerulosa cells and stimulates expression of cytochrome P-450 aldosterone synthase. The genes activated during this adrenal remodeling are not well defined. To clarify this mechanism, we sought to identify the genes whose expression is stimulated by A-II in the H295R cell line. Using a subtractive hybridization technique, we identified one clone whose expression was stimulated by A-II. The sequence of this gene was homologous to the human interferon-inducible genes, 9-27, 1-8D and 1-8U. The 5' portion of the gene was identical to the 1-8D gene product and the 3' was identical to the 9-27 gene product, but the existence of a transcript was not demonstrated by RT-PCR. The expression of these three genes was stimulated by A-II, with the 9-27 gene being most abundant. Potassium and forskolin also stimulated the expression of the 9-27 gene in the H295R cells, but not as effectively as did A-II or interferon-gamma.
