Cuprizone is a copper chelator that induces demyelination in the central nervous system when fed to mice. This compound is thought to target Complex IV and disrupt mitochondrial metabolism leading to loss of myelin-producing oligodendrocytes. In this proposal, we further examine the chemical and toxicological properties of cuprizone. Immunofluorescence imaging and microarray data on MO3.13 cells treated with cuprizone revealed the possibility of alterations in lysosomal function, as well as mitochondrial disruption via mTOR and Electron Transport Chain (ETC) related pathways. Cell viability assays conducted suggest that addition of Branched-Chain Amino Acids, most commonly used from literature, leucine, can increase …
Developmental Expression Of Rat Target Of The Antiproliferative Antibody (Rtapa) Protein In The Brain, Clyde Dale Sullivan
Developmental Expression Of Rat Target Of The Antiproliferative Antibody (Rtapa) Protein In The Brain, Clyde Dale Sullivan
Theses and Dissertations (ETD)
The present study defines the expression pattern of rTAPA (CD81) in the developing rat brain. rTAPA is a member of the tetramembrane spanning family of proteins, and like other members of this family, appears to be associated with the stabilization of cellular contacts. On immunoblots of the brain, rTAPA is present in higher levels than any other tissue examined: muscle, tendon, peripheral nerve, cartilage, liver, kidney, skin, and testicle. Immunohistochemical methods were used to define the distribution of rTAPA in the brain. This protein is expressed by ependyma, choroid plexus, astrocytes, and oligodendrocytes, and rTAPA is dramatically upregulated at the …
