The Role Of Line-1 Transposable Element In Methamphetamine Neurotoxicity In The Neurogenic Zones, Dongyue Yu
The Role Of Line-1 Transposable Element In Methamphetamine Neurotoxicity In The Neurogenic Zones, Dongyue Yu
Wayne State University Theses
Methamphetamine (METH) is a widely abused psychostimulant, which can cause neurotoxicity in the striatum and hippocampus. Several epigenetic changes were identified after binge METH exposure, including histone modification, DNA methylation, and changes in miRNA levels. We have shown that binge METH increases expression and activity of Long INterspersed Element (LINE-1), a transposable element, in doublecortin-positive neurons within rat neurogenic zones [1]. The goal of the present study was to identify which type(s) of cells show increases in LINE-1 following binge METH exposure, and determine whether binge METH-induced increases in LINE-1 are associated with cell death. To achieve this goal, male …

The Role Of E3 Ligase Parkin In Trafficking Of Monoamine Storage Vesicles In Rat Model Of Methamphetamine Neurotoxicity, Heli Dineshchandra Chauhan
Wayne State University Theses
Methamphetamine (METH), a psychostimulant, is a widely used drug of abuse. METH is toxic to dopaminergic (DAergic) and serotonergic (5-HT) nerve terminals in the striatum when administered at high doses. METH releases Dopamine (DA) from vesicular monoamine transporter 2 (VMAT2) containing synaptic vesicles and induces oxidative stress by auto-oxidation of DA. The VMAT2 plays a neurprotective role by sequestering cytoplasmic DA into vesicles for storage and protection from auto-oxidation. It has previously been shown that METH toxicity is associated with impaired VMAT2 trafficking and oxidative damage to the E3 ligase parkin. CDCrel1, a protein found to inhibit exocytosis, is regulated …
