title: The renin-angiotensin system in hybrid NG108-15 cells. Renin gene is from mouse neuroblastoma, angiotensinogen and angiotensin-converting enzyme genes are of rat glioma origin.
abstract: Angiotensin II (Ang II) increases the level of tyrosine phosphorylation of several proteins in nondifferentiated NG108-15 cells, a hybrid derived from the fusion of mouse neuroblastoma and rat glioma cells. Conversely, incubation of NG108-15 cells with an angiotensin-converting enzyme (ACE) inhibitor decreased the basal level of tyrosine phosphorylation of proteins, suggesting that locally secreted Ang II may act as an autocrine regulator. By RT-PCR, we found that nondifferentiated NG108-15 cells contained the mRNA transcript of the rat angiotensinogen, mouse renin and rat ACE genes, thus confirming that NG108-15 cells contain all the elements of a local renin-angiotensin system.
