ARL11 and posterior cortical atrophy: Using DAVID GO functional clustering, (http://david.abcc.ncifcrf.gov/tools.jsp) [25], [26] a strong association with nucleus and zinc-finger protein processes was illustrated when all the genes positively correlating with ARLTS1 expression (n = 36) in the PCa cell line cohort were taken into account (with a more stringent correlation value >0.50).
