SNAI1 and posterior cortical atrophy: Similar to the immunofluorescence staining results, an additive inhibitory effect of Snail and N-cadherin and additive upregulated effect of E-cadherin was observed in all EA and AA PCa cells under combined treatment (miR-99b-5p/Enz or miR-99b/Abi) vs. single agent (miR-99b-5p, Enz, or Abi alone).
