Figure 2B shows an average increase in YBX1 protein levels in AURKA-C4-2 cells from three independent experiments. Likewise, AURKA knockdown using corresponding shRNAs decreased YBX1 levels in C-42 cells (Figure 2C,D). Similar results were observed in 22Rv1 cells (Figure 2E–H), suggesting that AURKA positively controls YBX1 in PCa cells. This evidence concerns the gene AURKA and posterior cortical atrophy.
