MUC1 and posterior cortical atrophy: Recently, Somovilla et al. developed a highly sensitive fluorinated-proline-based MUC1 antigen for the detection of anti-MUC1 antibodies from PCa patient serum samples and reported that the detection of anti-MUC1 antibodies in PCa serum samples can be adapted for improved and early diagnosis of PCa compared to healthy individuals [131].
