MRI-informed muscle biopsies correlate MRI with pathology and DUX4 target gene expression in FSHD

Project description:Facioscapulohumeral muscular dystrophy (FSHD) is a common, dominantly inherited disease caused by the epigenetic de-repression of the DUX4 gene, a transcription factor normally repressed in somatic cells. As targeted therapies are now possible in FSHD, a better understanding of the relationship between DUX4 activity, muscle pathology and muscle MRI changes are crucial both to understand disease mechanisms and for the design of future clinical trials. Here, we performed MRIs of the lower extremities in 36 individuals with FSHD, followed by needle muscle biopsies in safely accessible muscles. We examined the correlation between MRI characteristics, muscle pathology, and expression of DUX4 target genes. Results show that the presence of elevated MRI STIR signal has substantial predictive value in identifying muscles with active disease and DUX4 target gene expression. In addition, DUX4 target gene expression was detected only in FSHD-affected muscles and not in control muscles, and higher levels of DUX4 target expression was associated with more advanced muscle pathology. These results support the use of MRI to identify FSHD muscles with active disease as measured by histopathology and DUX4 target gene expression and might be useful for the design of studies of disease progression and response to intervention.

DNA methylation analysis of melanoma progression to brain metastasis

Project description:Melanoma is one of the most aggressive and treatment-resistant cancers. It represents the most life-threatening neoplasm of the skin, and its incidence has been increasing for the last three decades. Melanoma evolves from the local transformation of melanocytes to primary tumors, which can metastasize to multiple organs. Brain metastases represent one of the most significant causes of death in cutaneous melanoma patients. Despite aggressive multi-modality threapy, patients with melanoma brain metastasis have a median survival of less than a year, with a majority of these patients dying as a result of their intracranial disease. We aimed to find brain metastasis-specific molecular markers. To identify alterations in DNA methylation related to brain metastasis, we used Illumina 450K BeadChips to assess differentially methylated regions in melanocytes, primary melanomas, lymph node metastases, and brain metastases. Bisulphite-converted DNA from 40 specimens was hybridised to the Illumina Infinium 450k Human Methylation BeadChip.

Data in support of Temporal changes of inflammation and endothelial dysfunction in multiple sclerosis related to the evolution of enhancing lesions on frequent brain MRI

Project description:Blood-brain-barrier (BBB) breakdown and active inflammation by relapsing–remitting (RRMS) lesions are hallmarks of multiple sclerosis (MS). Leaky endothelial junctions causes an increased expression of circulating immune cells with associated adhesion molecules on endothelial cell membrane but also an increased production of endothelial derived extracellular microvesicles (EV). Methods: Relapsing–remitting MS (RRMS) patients with no disease-modifying treatment were monitored with weekly intervals using high-resolution 3T MRI scanning. Plasma samples from each measurement were analyzed for protein biomarkers of inflammation by quantitative proteomics, cytokines and chemokines using multiplex immunoassay. Extracellular microvesicles were characterized by an optimized endothelial stress EV Array analysis for detection of soluble secreted microvesicles.
