NCX1 immunoprecipitates with the NHE1, as determined by KB-R7943 (HyKBR), silencing of the NCX1 (HysiNCX1) in SiHa cells (A) and by proximity ligation assay in RCC4 cells (B). Effectivity of silencing of the NCX1 was approximately 50%, as determined by Western blot analysis. No—normoxia, NC—negative control, Hy—hypoxia for 48 h.
