In muscle ATP is primarily known for its function as an energy source and as a mediator of the "excitation-transcription" process, which guarantees muscle plasticity in response to environmental stimuli. When quickly released in massive concentrations in the extracellular space as in presence of muscle membrane damage, ATP acts as a...

TSFM is a nuclear gene encoding the elongation factor Ts (EFTs), an essential component of mitochondrial translational machinery. Impaired mitochondrial translation is responsible for neurodegenerative disorders characterized by multiple respiratory chain complex defects, multisystemic involvement, and neuroradiological features of Leigh-like...

AIM: Since the immune system plays a role in the pathogenesis of several muscular dystrophies, we aim to characterize several muscular inflammatory features in α- (LGMD R3) and γ-sarcoglycanopathies (LGMD R5). MATERIALS AND METHODS: We explored the expression of major histocompatibility complex class I molecules (MHCI), and we analyzed the...

Mitochondrial disorders are a heterogeneous group of diseases sharing a defect of the oxidative phosphorylation system. Point mutations in the mitochondrial DNA are a common cause of mitochondrial disorders and frequently affect the sequences encoding mitochondrial transfer RNAs. The m.3271T>C mutation in the mitochondrial tRNALeu(UUR) is...

The acronym IBMPFD denotes a syndrome including inclusion body myopathy, Paget's disease of the bone (PDB) and frontotemporal dementia (FTD) as cardinal features, which is caused by missense mutations in the VCP gene. We studied the clinical characteristics and the histopathological features in two siblings and their mother who presented with...
