Marina Melixetian and her colleagues suppressed the expression of Geminin protein in human cells by treating the cells with small interfering RNAs (siRNAs) complementary to Geminin messenger RNA. Fortyâeight hours after treatment with siRNA, the Gemininâdepleted cells were enlarged and contained a single giant nucleus. Analysis of DNA content showed that many of these Gemininâdepleted cells were 4n or greater.
