Randomized trial reveals decreased mitochondrial protein synthesis in Huntington disease striatal models, indicating translation regulation issues.

This research aims to investigate the regulation of mitochondrial mRNA translation in Huntington disease and its effects on protein synthesis.
Utilized ribosome profiling (Ribo-Seq) to analyze ribosome occupancy on mitochondrial mRNA transcripts in HD and control striatal models.
Applied tandem mass tag-based mass spectrometry to identify mitochondrial proteins and correlate ribosome occupancy with protein abundance.
Compared ribosome occupancy and protein products in HD versus healthy control models.
Found diminished protein synthesis in HD mitochondria compared to control striatal cell models.
Ribosome occupancy was dramatically increased for mitochondrially encoded oxidative phosphorylation mRNAs in HD, while occupancy of nuclear-encoded mRNAs remained largely unaltered.
Detected a widespread dichotomous effect of increased ribosome occupancy but decreased mitochondrial protein products in HD.
