CXCR2 and posterior cortical atrophy: To determine the effect of CXCR1 and CXCR2 overexpression in MDA-PCa-2b cells tumorigenesis, we generated MDA-PCa-2b cell lines, stably overexpressing human CXCR1 (MDA-PCa-2b-CXCR1) or CXCR2 (MDA-PCa-2b-CXCR2), as well as control cells expressing the vector alone (MDA-PCa-2b-Vec).
