Drugging DNA Damage Repair Pathways for Trinucleotide Repeat Expansion Diseases. [PDF]

open access: yesJ Huntingtons Dis, 2021
DNA damage repair (DDR) mechanisms have been implicated in a number of neurodegenerative diseases (both genetically determined and sporadic). Consistent with this, recent genome-wide association studies in Huntington’s disease (HD) and other trinucleotide repeat expansion diseases have highlighted genes involved in DDR mechanisms as modifiers for age ...

Replication and Expansion of Trinucleotide Repeats in Yeast [PDF]

open access: greenMolecular and Cellular Biology, 2003
The mechanisms of trinucleotide repeat expansions, underlying more than a dozen hereditary neurological disorders, are yet to be understood. Here we looked at the replication of (CGG)(n) x (CCG)(n) and (CAG)(n) x (CTG)(n) repeats and their propensity to expand in Saccharomyces cerevisiae.

Chronic Exposure to Cadmium and Antioxidants Does Not Affect the Dynamics of Expanded CAG•CTG Trinucleotide Repeats in a Mouse Cell Culture System of Unstable DNA

open access: yesFrontiers in Cellular Neuroscience, 2021
More than 30 human disorders are caused by the expansion of simple sequence DNA repeats, among which triplet repeats remain the most frequent. Most trinucleotide repeat expansion disorders affect primarily the nervous system, through mechanisms of ...

Validation of methylation-specific polymerase chain reaction method and evaluation of FMR1 gene pre-mutations in premature ovarian insufficiency [PDF]

open access: yesمجله پزشکی دانشگاه علوم پزشکی تبریز, 2022
Background. Fragile X-associated premature ovarian insufficiency is clinically defined as a type of early ovarian failure with irregular menstrual cycles, increased follicle-stimulating hormone, premature menopause, and infertility.

Heterogenous Genetic, Clinical, and Imaging Features in Patients with Neuronal Intranuclear Inclusion Disease Carrying NOTCH2NLC Repeat Expansion

open access: yesBrain Sciences, 2023
Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative disorder that is caused by the abnormal expansion of non-coding trinucleotide GGC repeats in NOTCH2NLC.

RTEL1 Inhibits Trinucleotide Repeat Expansions and Fragility [PDF]

open access: goldCell Reports, 2016
Human RTEL1 is an essential, multifunctional helicase that maintains telomeres, regulates homologous recombination, and helps prevent bone marrow failure. Here, we show that RTEL1 also blocks trinucleotide repeat expansions, the causal mutation for 17 neurological diseases.
