frataxin deficiency in neonatal rat ventricular myocytes leads to mitochondrial dysfunction and oxidative stress, which would affect lipid metabolism.
Title: Frataxin deficiency in neonatal rat ventricular myocytes targets mitochondria and lipid metabolism.
Frataxin depletion caused mitochondrial membrane potential decrease, neurite degeneration and apoptotic cell death.
Title: Apoptotic cell death and altered calcium homeostasis caused by frataxin depletion in dorsal root ganglia neurons can be prevented by BH4 domain of Bcl-xL protein.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
