Author Response: Increased mtDNA Copy Number Protects Against LHON.
Although we appreciate the major interest of Josef Finsterer and Sinda Zarrouk-Mahjoub in our recent publication in Investigative Ophthalmology and Visual Science entitled ‘‘High Mitochondrial DNA Copy Number Is a Protective Factor from Vision Loss in Heteroplasmic Leber’s Hereditary Optic Neuropathy (LHON),’’ we wish to clarify two issues. First, in our published studies, our findings strongly...
متن کاملIncreased mtDNA Copy Number Does Not Protect Against LHON.
We read with interest the article by Bianco et al. about the mitochondrial DNA (mtDNA) copy number in 12 patients with Leber’s hereditary optic neuropathy (LHON) and 18 asymptomatic carriers of the primary LHON mutations m.11778G>A and m.3460G>A, respectively. The authors interpreted the increased mtDNA copy number in lymphocytes as a protective effect in LHON mutation carriers. We have the fol...
متن کاملMitochondrial transcription factor A regulates mtDNA copy number in mammals.
Mitochondrial DNA (mtDNA) copy number regulation is altered in several human mtDNA-mutation diseases and it is also important in a variety of normal physiological processes. Mitochondrial transcription factor A (TFAM) is essential for human mtDNA transcription and we demonstrate here that it is also a key regulator of mtDNA copy number. We initially performed in vitro transcription studies and ...
متن کاملTwinkle helicase is essential for mtDNA maintenance and regulates mtDNA copy number.
Mechanisms of mitochondrial DNA (mtDNA) maintenance have recently gained wide interest owing to their role in inherited diseases as well as in aging. Twinkle is a new mitochondrial 5'-3' DNA helicase, defects of which we have previously shown to underlie a mitochondrial disease, progressive external ophthalmoplegia with multiple mtDNA deletions. Mouse Twinkle is highly similar to the human coun...
متن کاملTy1 copy number dynamics in Saccharomyces.
To understand long terminal repeat (LTR)-retrotransposon copy number dynamics, Ty1 elements were reintroduced into a "Ty-less" Saccharomyces strain where elements had been lost by LTR-LTR recombination. Repopulated strains exhibited alterations in chromosome size that were associated with Ty1 insertions, but did not become genetically isolated. The rates of element gain and loss under genetic a...
