In 786-O and ACHN derived tumors, constitutive expression of PLA2R1 was found to affect tumor growth both by decreasing cell proliferation (as estimated by Ki-67 staining, Figure 3E-F and Supplementary Figure S4A-B) and increasing cell death (as estimated in TUNEL assays, Figure 3G-H and Supplementary Figure S4C-D). Here, MKI67 is linked to neoplasm.
