RASSF9 and cancer: Consistent with our results, RASSF7 was found to localize to the centrosome and knockdown of RASSF7 led to a failure in the formation of mitotic spindle and caused mitotic arrest of cells.[24] On the contrary, two recent studies have shown that RASSF9 was reduced in breast and gastric cancers and RASSF9 inhibits these cancer cell proliferation.[27, 37] The reason for this discrepancy may be due to the different cell types.
