The data have been accumulated that demonstrate specific expression patterns and levels of NADPH oxidase homologues (NoXs) and accessory genes in human cancer cell lines and primary tumors as well as modulation of these parameters by extracellular cues. our previous studies revealed that RDSproduction by human colorectal adenocarcinoma HT-29 cells is positively correlated with adaptor protein Ruk/CIN85 expression while increased levels of Ruk/CIN85 in weakly invasive human breast adenocarcinoma MCF-7 cells contribute to their malignant phenotype through the constitutive activation of Src/Akt pathway. In this study, to investigate whether overexpression of Ruk/CIN85 in MCF-7 cells can influence transcriptional regulation of NOXs genes, the subclones of MCF-7 cells with different levels of Ruk/CIN85 were screened for NoX1, NoX2, NoX3, NoX4, NoX5, DUoXl and DUoX2 as well as for regulatory subunitp22Phox mRNA contents by quantitative RT-PCR (qPCR). Systemic multidirectional changes in mRNA levels for NoXl, NoX2, NoX5, DUoX2 and p22Phox were revealed in Ruk/CIN85 overexpressing cells in comparison to control WT cells. Knocking down of Ruk/CIN85 using technology of RNA-interference resulted in the reversion of these changes. Further studies are necessary to elucidate, by which molecular mechanisms Ruk/CIN85 could affect transcriptional regulation of NoXs genes Additional Access Points: Bazalii, A. V. Horak, I. R.
