Abstract:
Dysregulation of iron metabolism and aberrant iron deposition has been associated with multiple sclerosis. However, the factors that contribute to this pathological state remain to be understood. In this study, human multiple sclerosis and mice brain samples were analyzed through mass spectrometry as well as histological and immunoblot techniques, which demonstrated that iron deposition is associated with increased levels of nuclear prelamin A recognition factor (NARF). NARF is a protein associated with the mitochondria which has also been linked to mitochondrial defects in multiple sclerosis. We report NARF to be associated in multiple sclerosis pathology and aberrant iron deposition.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
