PIDD1 and posterior cortical atrophy: Remarkly, KIF14 depletion induced cell cycle arrest, reduced proliferation and apoptosis in PCa cells at least partially through upregulating GADD45A, GADD45B, p21, PIDD and Shisa5, which contribute to growth arrest and apoptosis induction, and downregulating CCNB1 that promotes cell cycle progression.
