Genotype–Phenotype Correlations in Iranian Myotonic Dystrophy Type I Patients
Objectives: Myotonic Dystrophy type I (DM1) is a dominantly inherited disorder with a multisystemic pattern affecting skeletal muscle, heart, eye, endocrine and central nervous system. DM1 is associated with the expansion and instability of CTG repeat in the 3chr('39') untranslated region of the myotonic dystrophy protein kinase (DMPK) gene located on chromosome 19q13.3. The aim of this study w...
متن کاملNuclear RNA foci in the heart in myotonic dystrophy.
The disease mechanism underlying myotonic dystrophy type 1 (DM1) pathogenesis in skeletal muscle may involve sequestration of RNA binding proteins in nuclear foci of expanded poly(CUG) RNA. Here we report evidence for a parallel mechanism in the heart. Accumulation of expanded poly(CUG) RNA in nuclear foci is associated with sequestration of muscleblind proteins and abnormal regulation of alter...
متن کاملOral administration of erythromycin decreases RNA toxicity in myotonic dystrophy
OBJECTIVE Myotonic dystrophy type 1 (DM1) is caused by the expansion of a CTG repeat in the 3' untranslated region of DMPK. The transcripts containing an expanded CUG repeat (CUG (exp)) result in a toxic gain-of-function by forming ribonuclear foci that sequester the alternative splicing factor muscleblind-like 1 (MBNL1). Although several small molecules reportedly ameliorate RNA toxicity, none...
متن کاملPlasma microRNAs as biomarkers for myotonic dystrophy type 1
Myotonic dystrophy type 1 (DM1) lacks non-invasive and easy to measure biomarkers, still largely relying on semi-quantitative tests for diagnostic and prognostic purposes. Muscle biopsies provide valuable data, but their use is limited by their invasiveness. microRNA (miRNAs) are small non-coding RNAs regulating gene expression that are also present in biological fluids and may serve as disease...
متن کاملTranscriptome changes induced by toxic RNA in myotonic dystrophy
RNA-binding proteins play critical roles in RNA alternative processing during tissue development and maintenance. A striking example of the importance of developmental functions of these proteins is provided by the muscleblindlike (MBNL) protein family, which function as alternative splicing factors at multiple developmental stages from embryonic stem cell differentiation to postnatal switches ...
