MAPK8IP3 and posterior cortical atrophy: Univariate and multivariate Cox regression analyses were performed on MAPK8IP2 and its partner genes (MAPK8IP1, MAPK8IP3, MAP2K7, and MAP3K11), and the results showed that MAPK8IP2 and MAPK8IP3 were significantly associated with the progression-free interval of PCa patients (Table S4).
