In addition, clorgyline induces secretory epithelial cell-specific cell surface antigens including CD6, CD2, and CD79B, and represses basal cell-specific cell surface antigens including CD44, CD49B, and CD49C [24] (Table 2), suggesting that clorgyline promotes secretory differentiation in PCa cells. This evidence concerns the gene ITGA2 and posterior cortical atrophy.
