We found that the levels of p-YAP1-S127, a negative form of YAP1, were significantly downregulated in MYBL2-high expressing PCa tissues compared to those in MYBL2-low tissues (highest vs. lowest quartile, 0.1620 ± 0.09511 versus -0.2084 ± 0.1013, Z-score values, P = 0.008) (Figure 4A). Here, MYBL2 is linked to posterior cortical atrophy.
