RESUMO
<p><b>OBJECTIVE</b>To investigate the expression of rat protamine (RP) gene in MEL cells and the effect on cell growth.</p><p><b>METHODS</b>Eukaryotic expression plasmid pCR-3.1-RP was constructed and transfected into MEL cells. The changes of cell growth rate, mitotic index and colony-forming rate in semi-solid medium were investigated.</p><p><b>RESULTS</b>Transfected MEL cells showed lower growth rate, mitotic index and colony-forming rate. Volumes of cells were reduced and reduction of RNA transcription was observed.</p><p><b>CONCLUSION</b>These results suggest that expression of RP in MEL cell may inhibit the cell growth and proliferation.</p>
