BCL2 and posterior cortical atrophy: In PCa cells, HSP70 inhibits the mammalian STE20-like protein kinase 1(MST-1) mediated apoptosis [87] and promotes the overexpression of anti-apoptotic proteins such as myeloid leukemia cell differentiation protein-1 (Mcl-1 or Bcl2-L-3), apoptosis regulator Bcl-2 (BCL2), and Bcl-2-like protein 1 (Bcl2- L-1 or Bcl-X(L) [88].
