Ang has a prominent role in the pathology of cancer due to its functions in angiogenesis and cell survival. Since Ang possesses angiogenic activity, it makes Ang a possible candidate in therapeutic treatments of cancer. Studies of Ang and tumor relationships provide evidence for a connection between the two. The translocation of Ang to the nucleus causes an upregulation of transcriptional rRNA, while knockdown strains of Ang cause downregulation. The presence of Ang inhibitors that block translocation resulted in a decrease of tumor growth and overall angiogenesis. HeLa cells translocate Ang to the nucleus independent of cell density. In human umbilical vein endothelial cells (HUVECs), translocation of Ang to the nucleus stops after cells reach a specific density, while in HeLa cells translocation continued past that point. Inhibition of Ang affects the ability of HeLa cells to proliferate, which proposes an effective target for possible therapies.
