Subtype and cell type specific expression of lncRNAs provide insight into breast cancer

lncRNA expression according to breast cancer clinicopathological subtypes To identify lncRNAs expressed by specific breast cancer subtypes or associated with clinicopathological features, we analyzed RNA-sequencing data from two large independent breast cancer cohorts: SCAN-B (n = 3455)17 and TCGA-BRCA (n = 1095). We focused on lncRNAs annotated in the Ensembl18 v93 non-coding reference transcriptome…

Single-cell analyses define a continuum of cell state and composition changes in the malignant transformation of polyps to colorectal cancer

Mapping molecular changes across malignant transformation We generated single-cell data for 81 samples collected from eight FAP and seven non-FAP donors (Fig. 1a and Supplementary Tables 1 and 2). For each tissue, we performed matched scATAC-seq and snRNA-seq (10x Genomics). We obtained high-quality single-cell chromatin accessibility profiles for 447,829 cells…

Bio-informatic analysis of CRISPR protospacer adjacent motifs (PAMs) in T4 genome | BMC Genomic Data

The clustered regularly interspaced short palindromic repeats-Cas (CRISPR-Cas) defensive system is an acquired mechanism in prokaryotes which is analogous to RNAi in eukaryotes [1]. The CRISPR machinery is a complex immune strategy that is continually evolving in the bacterial genome to accommodate the rapid changes in the nucleic acids of…

A mammalian methylation array for profiling methylation levels at conserved sequences

Designing the mammalian methylation array The CMAPS algorithm is designed to select a set of Illumina Infinium array probes such that for a target set of species many probes are expected to work in each species (see “Methods” section). Array probes are sequences of length 50 bp flanking a target CpG…

RNA polymerase II trapped on a molecular treadmill: Structural basis of persistent transcriptional arrest by a minor groove DNA binder

Significance Hairpin pyrrole-imidazole (Py-Im) polyamides can be programmed to bind a broad repertoire of DNA sequences. Py-Im small molecules can be used to target cancer-specific coding regions and block transcription elongation. This transcription blockage by Py-Im cannot be rescued by transcription elongation factors, such as TFIIS. The mechanism by which…

Pan-AMPK activator O304 prevents gene expression changes and remobilisation of histone marks in islets of diet-induced obese mice

O304 treatment prevents islet gene expression signature changes induced by HFD We have previously demonstrated that the AMPK activator O304 improves blood glucose homeostasis in both human T2D subjects as well as in high-fat diet induced obese and diabetic mouse models. In the present study, we have now analysed the…

Homer finds same peak multiple times

I am using Homer to identify peaks in RNA-seq data and then determine differential expression by counting reads per peak. Homer has a lovely package that does just this: getDifferentialPeaksReplicates.pl. The issue is that for some reason Homer returns the same peak multiple times in its final output (Bonus question:…

RPKM on TSS using DiffBind

RPKM on TSS using DiffBind 1 Hi everyone, I want to extrapolate RPKM value from Diffbind. Investigated regions are TSS (± 2.5kb) but around 3500 TSS are “lost” because merged. I have read that in the new version of DiffBind is possible to use dbObj_region$config$mergeOverlap with negative value to avoid…

Frontiers | DNA Methylation and RNA-Sequencing Analysis Show Epigenetic Function During Grain Filling in Foxtail Millet (Setaria italica L.)

Introduction Gene expression is not only controlled by DNA sequences but also by epigenetic marks in eukaryotes. DNA methylation as one of the important epigenetic modifications has been demonstrated as closely related to gene expression in biological processes, such as transcriptional activity, developmental regulation, and environmental responses (Maunakea et al.,…

Multiform antimicrobial resistance from a metabolic mutation

Abstract A critical challenge for microbiology and medicine is how to cure infections by bacteria that survive antibiotic treatment by persistence or tolerance. Seeking mechanisms behind such high survival, we developed a forward-genetic method for efficient isolation of high-survival mutants in any culturable bacterial species. We found that perturbation of…
