NHEK cells were plated at a density of 8 x 10 000/cm2 and the cell cultures were grown for 24 hours before addition of 2 mM N-Acetyl-L-Cystein. RNA obtained from cultures grown for 1, 12 and 24 hrs after NAC treatment were compared to RNA from untreated cells at the corresponding time points. I.e 1 hour NAC treated vs 1 hour untreated cells etc. Each EXTRACT represents an individual mRNA extraction and subsequent cDNA synthesis from a batch of totalRNA originating from one cellculture dish.

RNA obtained from cultures grown for 1, 12 and 24 hrs after NAC treatment were compared to RNA from untreated cells at the corresponding time points. I.e 1 hour NAC treated vs 1 hour untreated cells etc. Each "SAMPLE" represents a biological replicate (i.e. separate cellcultures treated similarily) although I have given identical SAMPLE numbers in pairs.

View SamplesWe extracted RNA from whole cells and RNA from the cytoplasm and performed RNA sequening to compare differences in gene expression level and investigate what is the most appropriate estimate of the amount of mRNA present in a given cell population. The study was based on three human cell lines. Overall design: Analyze of transcriptome in 3 human cell lines (U-2 OS, A-431, U-251MG). Each cell line was prepared with four biological replicates for total RNA and four for cytoplasmic RNA.

View SamplesDevelopment and function of tissues and organs are powered by the activity of mitochondria. In humans, inherited genetic mutations that lead to progressive mitochondrial pathology often manifest during infancy and can lead to death, reflecting the indispensable nature of mitochondrial function and biogenesis. Here, we describe a zebrafish mutant for the gene mia40a, the life-essential homologue of the evolutionarily conserved Mia40 oxidoreductase which drives the biogenesis of cysteine-rich mitochondrial proteins. We report that mia40a mutant animals undergo progressive cellular respiration defects and develop enlarged mitochondria in skeletal muscles before their ultimate at the larval stage. We generated a rich transcriptomic and proteomic resource that allowed us to identify abnormalities in the development of endodermal organs, in particular the liver and pancreas. We identify the acinar cells of the exocrine pancreas to be severely affected by mutations in the MIA pathway. Our data contribute to a better understanding of the molecular, cellular and organismal effects of mitochondrial deficiency, important for the accurate diagnosis and future treatment strategies of these diseases. Overall design: Embryos obtained from an in-cross of heterozygous mia40awaw1/+ siblings were genotyped at 3 dpf. Pools of five mia40+/+ or mia40waw1/waw1 larvae, derived from the same clutch, were collected at indicated time-points for RNA extraction and transcriptomic profiling. Larvae used in 8 dpf experiments were subjected to external feeding from 5dpf before being collected for the analysis at 8dpf.

View SamplesForkhead box class O (FoxO) transcription factors regulate whole body energy metabolism, skeletal muscle mass and substrate switching. To elucidate the role of FOXO in skeletal muscle, dominant negative (dn) constructs for FOXO1 (FOXO1dn) or FOXO3 (FOXO3dn) were transfected by electroporation into mouse tibialis anterior muscle and glucose uptake, signal transduction, and glucose stimulated gene expression profiles were assessed. Results were compared against contralateral control transfected muscle.

View SamplesThe amount of RNA sequencing data on skeletal muscle is very limited. We have analyzed a large set of human muscle biopsy samples and provide extensive information on the baseline skeletal muscle transcriptome, including completely novel protein-coding transcripts. Overall design: Analyze of transcriptome in 23 skeletal muscle biopsy samples from six individuals. Four biopsies from each subject, two biopsies from each leg (except subject 6 which has only three biopsies in total).

View SamplesA subpopulation of pericytes expressing the Glast-CreERT2 transgene (Type A pericytes) has recently been identified as the main source of stromal scar tissue that forms after SCI. Identification of molecules associated with pericyte-derived scarring may offer new therapeutic targets to facilitate axon regeneration following central nervous system (CNS) injury. We conducted genome-wide RNA sequencing of (i) uninjured spinal cord segments and (ii) lesion sites presenting full or attenuated pericyte-derived scarring 14 days after SCI. Overall design: Adult Glast-Rasless-YFP (Glast-CreERT2 x R26R-YFP x Rasless) mice receiving vehicle (Veh) or tamoxifen (Tam) underwent dorsal hemisection at high thoracic level. Fourteen days after SCI, injury sites were dissected out, homogenized and total RNA was isolated from lesions presenting (i) dense (Veh, n=4) and (ii) attenuated (Tam, n=4) pericyte-derived scarring. Age-matched Glast-Rasless-YFP mice served as uninjured controls (n=4).

View SamplesAlthough the locations of promoters and enhancers have been identified in several cell types, we have yet limited information on their connectivity. We developed HiCap, which combines Hi-C with promoter sequence capture, to enable genome-wide identification of regulatory interactions with single-enhancer resolution. HiCap analyses of mouse embryonic stem cells (mESC) identified promoter-enhancer interactions predictive of gene expression change upon perturbation, opening up for genomic analyses of long-range gene regulation. Overall design: HiCap was designed by combining Hi-C with with sequence capture (for all promoters) and carried out in mouse embryonic stem cells (mESC)
