RNA interference (RNAi) is a widely used molecular biology technique to investigate the importance of specific genes in molecular pathways. Since mammalian cells are equipped with endogenous RNAi processing machinery, it has become common practice to transfect constructs that encode for short hairpin RNAs that are then cleaved to form the active RNAi(More)
Brain derived neurotrophic factor (BDNF) levels and signaling via the tyrosine receptor kinase B (TrkB) have been shown to be altered in Alzheimer’s Disease. In addition, it has been reported that the isoforms of TrkB can differentially affect metabolism of amyloid precursor protein (APP). Conversely, A, a neurotoxic cleavage product of APP, has been shown(More)
Selenium is an essential trace element that is incorporated into 25 human proteins as the amino acid selenocysteine (Sec). The incorporation of this amino acid turns out to be a fascinating problem in molecular biology because Sec is encoded by a stop codon, UGA. Layered on top of the canonical translation elongation machinery is a set of factors that exist(More)
Selenocysteine (Sec) is a critical residue in at least 25 human proteins that are essential for antioxidant defense and redox signaling in cells. Sec is inserted into proteins cotranslationally by the recoding of an in-frame UGA termination codon to a Sec codon. In eukaryotes, this recoding event requires several specialized factors, including a dedicated,(More)
