The involvement of miRNA in mesial temporal lobe epilepsy (MTLE) pathogenesis has increasingly become a focus of epigenetic studies. Despite advances, the number of known miRNAs with a consistent expression response during epileptogenesis is still small. Addressing this situation requires additional miRNA profiling studies coupled to detailed individual expression analyses. Here, we perform a miRNA microarray analysis of the hippocampus of Wistar rats 24 hours after intra-hippocampal pilocarpine ...[more]

miRNA post transcriptional control of umbilical cord mesenchymal stem cell osteogenic differentiation.

Project description:Umbilical cord mesenchymal stem cells were stimulated to osteogenesis by 24h, 48h and 7 days. Undifferentiated and treated cells have their total RNA extracted and 25 ug were used to extract micro RNAs by Flash PAGE Fractionator (Ambion). These miRNA were labeled and used to hybridize to 662 oligo arrays corresponding to miRNA sequences from human, rat and mouse. The hybridized slides were scanned in the Amersham Automatic Slide Processor, quantified by TIGR Spotfinder software and submitted to stathiscal treatment in TIGR MEV software.

Expression data from C. elegans during L3 and L3-lethargus

Project description:To identify genes differentially expressed during L3 lethargus, we collected RNA during the third larval stage (L3) lethargus period, 37 hours after feeding developmentally-arrested L1 animals. Animals in lethargus were identified based on quiescence of locomotion and feeding. Additional time point for RNA collection was in the mid-L3 stage, 32 hours after feeding developmentally-arrested L1 animals. These samples were interrogated with the Affymetrix C. elegans Genome Array. A total of 153 gene transcripts were up regulated, and 48 gene transcripts were down regulated, during the L3 lethargus period compared to the L3 stage (false discovery rate (FDR) < 0.05). There were 2 groups and 3x replication for each group, for 6 total samples. The groups were (1) L3 and (2) L3-lethargus. We compared L3-lethargus vs L3 using R/maanova. The permutation based p-values for each test were significant for FDRM-bM-^IM-$5%.

Prostate miRNA expression profiles

Project description:Comparison of miRNA expression profiles in normal and malignant prostate tissues. Keywords: microarray analysis of microRNA expression profiles MicroRNA expression was compared between normal prostate tissue from either young subjects that died of trauma, or normal adjacent to tumor, and prostatic tumors in older prostate cancer patients. RNA was isolated from frozen tissue sections, enriched for the miRNA fraction, which was subsequently labeled and hybridized to miRNA microarrays for expression profiling analysis.

B. subtilis response to rotten meat volatiles.

Project description:To find a promoter upregulated in the presence of rotten meat, we exposed B. subtilis 168 to the volatiles of rotten meat (mixed beef/pork) and performed a microarray comparing it to B. subtilis which was not exposed to the meat. The results where used to build iGEM Groningen 2012s Food Warden, a spoiled meat detector. Find more information at: 2012.igem.org/Team:Groningen One condition design; including dye swap, two technical replicates and two experimental replicates

RNA-seq transcriptional profiling of peripheral blood leukocytes from cattle infected with Mycobacterium bovis

Project description:In the present study, we have analyzed the peripheral blood leukocyte (PBL) transcriptome of eight natural M. bovis-infected and eight age- and sex-matched non-infected control Holstein-Friesian animals using RNA-seq. In addition, we compared gene expression profiles generated using RNA-seq with those previously generated using the high-density AffymetrixM-BM-. GeneChipM-BM-.

shoots and roots treated with methotrexate and 5-formyl-thf-Transcriptomic and metabolic changes in Arabidopsis thaliana supplemented with 5-CHO-THF and its relationship with the accumulation and transformation to THF active derivatives

Project description:au11-02_cho-thf - shoots and roots treated with methotrexate and 5-formyl-thf - Folates and 1C metabolism - The objective of this study is to investigate the changes on the plant expression profiles due to 5-CHO-THF assimilation and transformation. Additionally, plants supplemented with methotrexate (MTX) (an inhibitor of folate biosynthesis) will complement the study. Results from this work will serve to better understand the effects of folate accumulation in plants. 12 dye-swap - treated vs untreated comparison

miRNA expression in fast and slow skeletal muscle of wild type and SOD1-G93A mice

Project description:Amyotrophic lateral sclerosis (ALS) is a lethal motor neuron disease that progressively debilitates neuronal cells that control voluntary muscle activity. In a mouse model of ALS that expresses mutated human superoxide dismutase 1 (SOD1-G93A) skeletal muscle is one of the tissues affected early by mutant SOD1 toxicity. Fast-twitch and slow-twitch muscles are differentially affected in ALS patients and in the SOD1-G93A model, fast-twitch muscles being more vulnerable. We used miRNA microarrays to investigate miRNA alterations in fast-twitch (EDL) and slow-twitch (soleus) skeletal muscles of symptomatic SOD1-G93A animals and their age-matched wild type littermates. At age of 90 days RNA was extracted from extensor digitorum longus (EDL) and soleus (SOL) muscles of male SOD1-G93A animals and their age-matched wild type male littermates. RNA was hybridized on Affymetrix Multispecies miRNA-2_0 Array.
