Transcriptome profiling of fgps1 mutant inflorescence stem
Ontology highlight
ABSTRACT: Total RNA was isolated from 35-d old inflorescence stems of plants. For microarray analysis, three biological replicates were included for both WT control and fpgs1 mutant.
Project description:We used microarrays to characterize the gene expression changes in liver caused by high fat diet feeding to C57BL/6 WT and miR-155-/- mice. Livers were collected from male mice at 24 weeks of age for RNA extraction and hybridization on Affymetrix mouse gene 1.0 ST array . We extracted RNA from 3 animals/group for microarray analysis (total N = 6 samples)
Project description:Paired synovial and peripheral blood CD14+ cells were obtained from patients with active rheumatoid arthritis and compared to each other
Project description:Multiciliated cells possess multiple motile cilia on the cell surface and are widely distributed throughout the vertebrate body to perform important physiological functions by regulating fluid movement in the intercellular space. However the molecular mechanisms underlying multiciliogenesis are not well understood. Although dysregulation of members of the miR-34 family plays a critical role in the progression of various cancers, the physiological function of miR-34b, especially in regulating multiciliogenesis, is largely unknown. Here we focus on the multiciliated cells in the zebrafish kidney to study whether and how miR-34b regulate multiciliogenesis. We performed genome-wide gene expression profiling of zebrafish kidney multiciliated cells in the absence (miR-34b morpholino) or presence of miR-34b (control morpholino). RNA samples for microarray gene expression profiling were collected at 3 days post fertilization.
Project description:Canine distemper virus (CDV)-induced demyelinating leukoencephalitis (CDV-DL) in dogs is a translational animal model for human demyelinating diseases such as multiple sclerosis. The aim of this study was to perform an assumption-free microarray analysis of gene expression in different subgroups of CDV-DL as compared to normal controls. Dogs were classified into normal controls (group 1), acute CDV-DL lesions with CDV within the brain but without demyelination and inflammation (group 2), subacute lesions with demyelination but without inflammation (group 3), and subacute to chronic lesions with demyelination and inflammation (group 4).
Project description:We performed a comparative genomics approach between im mutant and TM-1 in order to understand the function of im gene reducing the degree of fiber cell wall development. We compared transcriptome profiles of developing fibers (10, 17, and 28 days post anthesis (DPA)) between two NILs using Affymetrix cotton array chip containing 21,854 transcripts.
Project description:Transcriptional profiling of upper flanks and lower flanks of Arabidopsis inflorescence stems after gravistimulation. Candidate genes which were up-regulated in the lower flanks relative to the upper falanks after gravi-stimulation at 30 min were identified. Two time-points experiments, at 10 min and 30 min. Biological replicates: 2 replicates for each experiments (as color swapped data)
Project description:Homozygous T4 SND2-overexpressing Arabidopsis plants were grown alongside the wild type and the lower 100 mm of primary inflorescence stems sampled at 4 and 8 weeks of age A direct comparison was used (box plot). Three biological replicates and two technical replicates (dye swaps) were included for each experiment
Project description:A comparison of human cardiac gene expression profile in paired samples of right atrium and left ventricle extracted in vivo from female patients. With the purpose to compare results from the corresponding dataset from male patients (E-MEXP-3396)
Project description:To investigate whether the transcriptional response to carbon (C) depletion and sucrose re-addition depend on the duration of C-depletion, Arabidopsis thaliana seedlings growing in liquid culture in weak continuous light were harvested 3, 6, 12, 24, 48 and 72 h after removing sucrose from the medium, and 30 min after resupplying sucrose at each of these times. After removing sucrose, soluble sugars fell strongly within 3 h, and starch was gradually depleted over 24 h, and hexose phosphates and ATP declined gradually over 72 h. Expression profiling using ATH arrays pointed to Overall the transcriptional response pointed to early transcriptional remodelling of metabolism to conserve C, followed by induction of photosynthesis and pathways that recycle C, and repression of growth-related processes. The time-dependent transcriptional response to C-depletion differed from that during a light/dark cycle and an extended night. Re-supplying sucrose for 30 min led to near-complete recovery of seedling sucrose levels, partial recovery of reducing sugars and phosphorylated intermediates, but no immediate change of starch or ATP. The rapid transcriptional response to sucrose readdition was conserved across the entire C-depletion time course, became larger with time. , and was highly enriched for regulatory genes. Whilst there was a rapid decrease of many C-depletion-induced transcripts, fewer transcripts increased. The majority of the transcripts that responded rapidly after resupplying sucrose also decreased after treating C-depleted seedlings with the transcriptional inhibitor cordycepin A, pointing to an important role for transcript turnover in the rapid response to sucrose.
