Moreover, in the ZA chemo-resistant DU145R80 PCa cells we identified a homogeneous group of 15 proteins differently expressed that were associated, for the most part, with regulation of cell morphology, cytoskeletal organization, cell movement and/or cell-to-cell interaction: one of these significantly deregulated proteins was identified as annexin A1 (ANXA1) [10]. The gene discussed is ANXA1; the disease is posterior cortical atrophy.
