Ruk/CIN85 is an adaptor protein that plays important roles in the regulation of cellular processes such as cell death, proliferation and motility. It was recently shown that overexpression of Ruk/CIN85 increases the oncogenic potential of human breast adenocarcinoma MCF-7 cells. It was the aim of the present study to investigate whether inhibition of Ruk/CIN85 expression has an effect on the biological properties of the cells. In order to down-regulate Ruk/CIN85 expression of small interfering RNA-based approach was used. For down-regulation of Ruk/CIN85 lentiviral constructs encoding Ruk/CIN85-specific small hairpin RNA sequences were generated. By using the obtained recombinant lentiviruses it was shown that inhibition of Ruk/CIN85 expression influences biological properties (motility, proliferation, ABCG2 expression, and ROS generation) of various tumour cell types such as human breast adenocarcinoma MCF-7, human colorectal adenocarcinoma HT-29, and Lewis mouse lung carcinoma cells.

Key words: adapter proteins, Ruk/CIN85, RNAinterference, lentiviral vectors, cell motility, active oxygen forms.
