RIC8A expression levels associated with different molecular parameters. A: Gene expression in the Miller et al. 2005 data : The 251 breast tumours separated based on ER, PR and TP53 status. TP53 mutated group includes all tumours with a signature of TP53 inactivation . B: Gene expression in the Naume et al. 2007 data : The 115 breast tumours separated based on ER, PR and TP53 status. C: RIC8A expression by TaqMan qRT-PCR. The 38 tumours separated based on TP53 mutation status. Each square represents the expression level of RIC8A in one tumour. Red bars indicate group medians.
