KLK4 and posterior cortical atrophy: The clinical parameters concerning miR-378 in PCa analysis have been reported by Margaritis Avgerish et al., who indicated that the KLK2 and KLK4 genes are highly correlated with miR-378 levels in PCa patients; particularly, a lower expression of miR-378 in PCa patients is significantly related to short-term recurrence when compared with control subjects (p value = 0.005) [30].
