Torres said there are some cancer clinical trials testing kinesin inhibitors, but so far they have not proved very successful. The inhibitors do stop cell division, but they don't damage the cell enough to induce a quick cell death and eventually the cells begin dividing again.
STARD9, however, not only arrests cells during division, it causes so much disruption in spindle formation and function that the cells die quickly. The cells, in effect, become too broken to repair themselves, Torres said.
