Disease
ANGI_HUMAN Defects in ANG are the cause of susceptibility to amyotrophic lateral sclerosis type 9 (ALS9) [MIM:611895. ALS is a degenerative disorder of motor neurons in the cortex, brain stem and spinal cord. ALS is characterized by muscular weakness and atrophy.[1] [2] [3] [4] [5] [6]
Function
ANGI_HUMAN May function as a tRNA-specific ribonuclease that abolishes protein synthesis by specifically hydrolyzing cellular tRNAs. Binds to actin on the surface of endothelial cells; once bound, angiogenin is endocytosed and translocated to the nucleus. Angiogenin induces vascularization of normal and malignant tissues. Angiogenic activity is regulated by interaction with RNH1 in vivo.[7] [8]
Publication Abstract from PubMed
Angiogenin (Ang) is a potent angiogenic protein that is overexpressed in many types of cancer at concentration values correlated to the tumor aggressiveness. Here, by means of an integrated multi-technique approach based on crystallographic, spectrometric and spectroscopic analyses, we demonstrate that the anti-cancer drug oxaliplatin efficiently binds angiogenin. Microscopy cellular studies, carried out on the prostate cancer cell (PC-3) line , show that oxaliplatin inhibits the angiogenin prompting effect on cell proliferation and migration, which are typical features of angiogenesis process. Overall, our findings point to angiogenin as a possible target of oxaliplatin, thus suggesting a potential novel mechanism for the antineoplastic activity of this platinum drug and opening the avenue to novel approaches in the combined anti-cancer anti-angiogenic therapy.
