Beskrivning

The MAb 26-2F recognizes human angiogenin. Angiogenin is a secreted ribonuclease (RNASE)-family member and is important for the formation of new blood vessels as well as the stimulation of cell proliferation and survival. Cellular stress signals direct angiogenin to stress granules where angiogenin functions by hydrolyzing cellular tRNA resulting in modulation of protein translation and promotion of cell survival. Cytoplasmic angiogenin can bind to actin, forming complexes that activate protease cascades which can degrade laminin and fibronectin allowing endothelial cells to penetrate the basement membrane and migrate. In cancer cells, growth signals direct angiogenin translocation to the nucleus where binding of DNA promotor regions stimulates rRNA transcription resulting in a downstream increase in protein synthesis driving cell growth and survival. Angiogenin is upregulated in multiple cancers including breast, prostate, cervical, colorectal, lymphoma, and melanoma. During development and in adulthood, angiogenin is highly expressed in the spinal cord and contributes to motor neuron survival. Angiogenin is important for neuronal survival and is depleted in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and Parkinson's disease. This 26-2F antibody is reported to have both in vivo and in vitro neutralizing activity to angiogenin.

Angiogenin (ANG or ANG I) is important for the process of neovascularization and formation of new blood vessels. ANG is similar to pancreatic ribonuclease A and functions as a tRNA-specific ribonuclease that abolishes protein synthesis by specifically hydrolyzing cellular tRNAs. It interacts with endothelial cell-surface actin and may cause changes in the cell cytoskeleton. ANG is thought to be involved in the development of solid tumors and its antagonists are capable of inhibiting tumor growth. Defects in ANG are the cause of susceptibility to amyotrophic lateral sclerosis type 9 (ALS9). Angiogenin is a genetic link between ALS and PD.
