GSK3B and posterior cortical atrophy: WB further showed that upregulated LIFR‐K620 acetylation, LIFR‐S1044 phosphorylation and AKT‐S473 phosphorylation were followed by PCa progression and acted on the AKT signalling pathway, as shown by changes in the downstream effectors of PI3K/AKT signalling, phospho‐S6 and phospho‐GSK3β (Figure 3G).
