CSNK2A2 and ovarian cancer: However, the shear stress stimulation protocol also decreased expression of the CSNK2A2 (OVCAR-3 and SKOV-3; Figure 7A): the same target was identified among a gene expression panel correlating with ovarian cancer progression in vivo and in vitro, hence supporting the complexity of the physically induced signature and the difficulty to draw conclusions on the bases of one single protein or target.
