LPS-treatment of bovine endometrial epithelial cells causes differential DNA methylation of genes associated with inflammation and endometrial function. BMC Genomics. BackgroundLipopolysaccharide LPS endotoxin stimulates pro-inflammatory pathways and is a key player in the pathological mechanisms involved in the development of endometritis. When comparing DNA methylation results at 24h to time 0h, a larger proportion of hypomethylated regions were identified in the LPS-treated groups, whereas the trend was opposite in controls. Differential methylation analysis revealed that effects of LPS treatment were associated with methylation changes for genes involved in regulation of immune and inflammatory responses, cell adhesion, and external stimuli.Comparing Differential Gene Expression Of The European - exact answer

Phenotype-based compound screening has advantages over target-based drug discovery, but is unscalable and lacks understanding of mechanism of drug action. A chemical-induced gene expression profile provides a mechanistic signature of phenotypic response; however, the use of such data is limited by their sparseness, unreliability and relatively low throughput. Few methods can perform phenotype-based de novo chemical compound screening. Here we propose a mechanism-driven neural network-based method, DeepCE—which utilizes a graph neural network and multihead attention mechanism to model chemical substructure—gene and gene—gene associations—for predicting the differential gene expression profile perturbed by de novo chemicals. Moreover, we propose a novel data augmentation method that extracts useful information from unreliable experiments in the L dataset. The experimental results show that DeepCE achieves superior performances to state-of-the-art methods. Comparing Differential Gene Expression Of The European
Background
Metrics details. Despite the increasing use of RNAseq for transcriptome analysis, microarrays remain a widely-used methodology for genomic studies.
We previously developed a methodology, the Sscore algorithm, for probe-level identification of differentially expressed genes DEGs between treatment and control samples with oligonucleotide microarrays. The Sscore algorithm was validated for sensitive detection of DEGs by comparison with existing methods. Here we describe Diffedential GCSscore link, which utilizes the GC-content of a given oligonucleotide probe to estimate non-specific binding using antigenomic background probes found on new generations of arrays.
We implemented this algorithm in an improved GCSscore R package for analysis of modern oligonucleotide microarrays. By utilizing the direct probe-level intensities, the GCSscore algorithm was able to detect DEGs under stringent statistical criteria for all Clariom-based arrays. Despite the advent of RNAseq for transcriptomics analysis, microarrays continue to be widely used with an average of over PubMed listings per year in — for this technology.
Associated Data
A major commercial platform for microarray analysis, produced originally by Affymetrix and now by Thermo-Fisher, utilizes collections of oligonucleotides distributed across cognate genes to probe RNA expression by hybridization. This entailed comparing individual oligonucleotide probes within each probeset between two samples, after applying a heteroscedastic error correction model. The Sscore method Comparing Differential Gene Expression Of The European an easily interpretable standard normal distribution GGene expression differences between two samples for a given probeset, akin to a z-score transformation. Prior work demonstrated the advantage of the Sscore method over probe summarization techniques such as RMA for Affymetrix microarray analysis, particularly for experiments having smaller numbers of replicates [ 23 ].
This advantage prompted development of a Bioconductor R package, sscorefor application of the original Sscore method on Affymetrix microarrays [ 4 ].
Access options
The original Sscore relies on the difference between perfect match PM and cognate mismatch MM probes to correct for non-specific hybridization while calculating a measure of expression difference between two samples. MM probes were designed to capture array background noise rawQ and non-specific binding NSB of off-target transcripts. However, MM probes were subsequently shown to be an inconsistent measure source non-specific binding [ 13 ].]
