Repeated, intermittent exposure to psychostimulants or stressors results in long-lasting, progressive sensitization of the behavioral effects of a subsequent amphetamine (AMPH) challenge. Although behavioral sensitization has also been observed following a single drug pretreatment, the sensitizing potential of a single exposure to stress is not clear. Both(More)
Mitochondria are involved in many essential cellular activities. These broad functions explicate the need for the well-orchestrated biogenesis of mitochondrial proteins to avoid death and pathological consequences, both in unicellular and more complex organisms. Yeast as a model organism has been pivotal in identifying components and mechanisms that drive(More)
The mitochondrial protein AFG3L2 forms homo-oligomeric and hetero-oligomeric complexes with paraplegin in the inner mitochondrial membrane, named m-AAA proteases. These complexes are in charge of quality control of misfolded proteins and participate in the regulation of OPA1 proteolytic cleavage, required for mitochondrial fusion. Mutations in AFG3L2 cause(More)
The content of mitochondrial proteome is maintained through two highly dynamic processes, the influx of newly synthesized proteins from the cytosol and the protein degradation. Mitochondrial proteins are targeted to the intermembrane space by the mitochondrial intermembrane space assembly pathway that couples their import and oxidative folding. The folding(More)
APE1 is a multifunctional protein with a fundamental role in repairing nuclear and mitochondrial DNA lesions caused by oxidative and alkylating agents. Unfortunately, comprehensions of the mechanisms regulating APE1 intracellular trafficking are still fragmentary and contrasting. Recent data demonstrate that APE1 interacts with the mitochondrial import and(More)
Mitochondria are central power stations in the cell, which additionally serve as metabolic hubs for a plethora of anabolic and catabolic processes. The sustained function of mitochondria requires the precisely controlled biogenesis and expression coordination of proteins that originate from the nuclear and mitochondrial genomes. Accuracy of targeting,(More)
