Abstract
SURF6 is a bona fide nucleolar protein comprising an evolutionary conserved family that extends from human to yeast The expression of the mammalian SURF6 has been recently found to be regulated during the cell cycle In order to determine the importance of SURF6 in mammalian cells we applied the TetOn system to regulate conditionally in response to tetracycline the expression of an antisense RNA asRNA that targets Surf6 mRNA in mouse NIH/3T3 cells Induced Surf6 asRNA caused an effective depletion of SURF6 protein resulted in cell death and in an apparent arrest in the G1 phase of the cell cycle These results provide for the first time evidence that expression of SURF6 is essential for mammalian cell viability and suggest that SURF6 might participate in the progression of cell cycleWe are grateful to thank SV Khaidukov for flow cytometry The pUHrT621 vector was a generous gift from Prof Wolfgang Hillen University Erlangen Germany M Polzikov has been supported by INTAS Grant No 03550570 This work was supported by the Russian Foundation for Basic Research Grant No 040448391
