The R6/2 mouse is the most frequently used model for experimental and preclinical drug trials in Huntington's disease (HD). When the R6/2 mouse was first developed, it carried exon 1 of the huntingtin gene with ~150 cytosine-adenine-guanine (CAG) repeats. The model presented with a rapid and aggressive phenotype that shared many features with the human condition and was particularly similar to ...
The genetic mutation in Friedreich ataxia (FRDA) is a hyperexpansion of the triplet-repeat sequence GAA·TTC within the first intron of the FXN gene. Although yeast and reporter construct models for GAA·TTC triplet-repeat expansion have been reported, studies on FRDA pathogenesis and therapeutic development are limited by the availability of an appropriate cell model in which to study the mechan...
To investigate a possible involvement of expanded triplet repeats of genome in the genomes of patients with endogenous psychoses, we examined a CAG repeat polymorphism in the coding region of the KCNN3 gene in schizophrenia, schizoaffective disorder, bipolar disorder and controls of the Japanese population. There were no significant differences in the CAG repeat number of longer or shorter alle...
friedreich’s ataxia (fa) is the commonest genetic cause of ataxia and is associated with the expansion of a gaa repeat in intron 1 of the frataxin gene. iron accumulation in the mitochondria of patients with fa results in hypersensitivity to oxidative stress. mitochondrial dna (mtdna) could be considered a candidate modifier factor for fa disease since mitochondrial oxidative stress is thought ...
The association between polymorphism of androgen receptor gene CAG (AR-CAG) and male infertility in several studies was controversial. Based on studies on association between AR-CAG repeat length and male infertility in recent years, an updated meta-analysis is needed. We aimed to evaluate the association between AR-CAG repeat length and male infertility in advantage of the data in all publishe...
OBJECTIVE Despite technical difficulties due to mediastinal fibrosis, repeat mediastinoscopy can be a valuable tool in the restaging of lung cancer. It provides essential pathological information on mediastinal invasion when selecting patients for surgical resection after induction chemotherapy in stage IIIa disease. The aim of our study was to evaluate the feasibility, sensitivity and accuracy...
we reportedhere data from a productivity veterinary service that was participatory planned and delivered on farms at the kanihari union belongs to mymensingh district of bangladesh. we used a set of five forms and a breeding calendar on farm visit once in a month to guide service delivery and acquisition of data and to keep the records on general cattle health, reproduction, udder health and fe...
