GNA12 and GNA13 are highly expressed in aggressive cancer cells. (A) Immunoblot showing the GNA12 and GNA13 protein expression in different breast cancer cell lines. Tubulin is used as loading control. (B) Basal and FCS-induced invasion of MCF-10a and MDA-MB-231 cells. All values are expressed as fold change relative to basal invasion of MCF-10a cells.
