Consequently, we cloned the full-length versions of PIK3CD-S from AA PCa cell line MDA PCa 2b, and PIK3CD-L from MDA PCa 2b as well as EA PCa cell lines VCaP and LNCaP using standard molecular approaches (5′- and 3′-RACE (rapid amplification of cDNA ends)34). This evidence concerns the gene PIK3CD and posterior cortical atrophy.
