16. Results suggest that lamin A/C might constitute a type of epithelial marker that better signifies EMT and MET in prostate cancer tissue, since a decrease in lamin A/C expression in Gleason score (GS) 4 is likely associated with the EMT process, while the re-expression of lamin A/C in GS 5 is likely linked with MET.
