C9ORF72-ALS/FTD: Transgenic Mice Make a Come-BAC
For five years, since the landmark discovery of the C9ORF72 hexanucleotide repeat expansion in ALS/FTD, a transgenic mouse model has remained elusive. Now, two laboratories (Liu et al., 2016; Jiang et al., 2016) report the development of BAC transgenic mice that recapitulate features of the human disease.
متن کاملExpression of human CAR splicing variants in BAC-transgenic mice.
The nuclear receptor constitutive androstane receptor (CAR) is a key regulator for drug metabolism in liver. Human CAR (hCAR) transcripts are subjected to alternative splicing. Some hCAR splicing variants (SVs) have been shown to encode functional proteins by reporter assays. However, in vivo research on the activity of these hCAR SVs has been impeded by the absence of a valid model. This study...
متن کاملC9orf72 BAC Transgenic Mice Display Typical Pathologic Features of ALS/FTD
Noncoding expansions of a hexanucleotide repeat (GGGGCC) in the C9orf72 gene are the most common cause of familial amyotrophic lateral sclerosis and frontotemporal dementia. Here we report transgenic mice carrying a bacterial artificial chromosome (BAC) containing the full human C9orf72 gene with either a normal allele (15 repeats) or disease-associated expansion (∼100-1,000 repeats; C9-BACexp)...
متن کاملC9orf72 BAC Mouse Model with Motor Deficits and Neurodegenerative Features of ALS/FTD
To define how the C9orf72 GGGGCC expansion mutation causes ALS/FTD and to facilitate therapy development, a mouse model that recapitulates the molecular and phenotypic features of the disease is urgently needed. Two groups recently reported BAC mouse models that produce RNA foci and RAN proteins but, surprisingly, do not develop the neurodegenerative or behavioral features of ALS/FTD. We now re...
متن کاملHuman C9ORF72 Hexanucleotide Expansion Reproduces RNA Foci and Dipeptide Repeat Proteins but Not Neurodegeneration in BAC Transgenic Mice
A non-coding hexanucleotide repeat expansion in the C9ORF72 gene is the most common mutation associated with familial amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). To investigate the pathological role of C9ORF72 in these diseases, we generated a line of mice carrying a bacterial artificial chromosome containing exons 1 to 6 of the human C9ORF72 gene with approximately 5...
