In-Depth Analysis of Bacillus anthracis 16S rRNA Genes and Transcripts Reveals Intra- and Intergenomic Diversity and Facilitates Anthrax Detection

Various ratios of 16S-BA/BC-alleles constitute possible explanations for differences in FISH signals of cells of diverse B. anthracis strains (Fig. 1). Indeed, we found a significant correlation between 16S-BA/BC-allele ratios in sequenced genomes and mean intensities of the Cy3 FISH signals targeting the16S-BA-allele (tested with the cor.test function in R, Pearson’s…

Identification of a regulatory pathway inhibiting adipogenesis via RSPO2

Integration of APC scRNA-seq data reveals heterogeneity of adipocyte progenitor cells In a previous study9, we defined Lin−Sca1+CD142+ APCs as adipogenesis regulatory (Areg) cells and demonstrated that these cells are both refractory toward adipogenesis and control adipocyte formation of APCs through paracrine signaling. In contrast, Merrick et. al.4 observed that Lin−CD142+ cells…

The role of ATXR6 expression in modulating genome stability and transposable element repression in Arabidopsis

Significance The plant-specific H3K27me1 methyltransferases ATXR5 and ATXR6 play integral roles connecting epigenetic silencing with genomic stability. However, how H3K27me1 relates to these processes is poorly understood. In this study, we performed a comprehensive transcriptome analysis of tissue- and ploidy-specific expression in a hypomorphic atxr5/6 mutant and revealed that the…

Discovery and Biosynthesis of Natural Products from New Zealand Soil Metagenome Libraries

Antibiotic discovery rates dramatically declined following the “golden age” of the 1940’s to the 1960’s.

Trouble running Cyclum for my scRNA-seq analysis

I have been analyzing some mouse T cell scRNA-seq data for a few months now using mostly the Seurat pipeline run with default parameters, and I have noticed that regressing out the ‘S.Score’ and ‘G2M.Score’ obtained from default Seurat::CellCycleScoring seems to be insufficient to remove (seemingly large) variation originating from…

Bacterial endosymbionts protect beneficial soil fungus from nematode attack

A healthy soil nourishes plants and animals, purifies water and air, and promotes sustainable agriculture. Characteristic for highly complex and competitive soil ecosystems are the frequent and direct interactions between all soil-dwelling microorganisms, animals, and plants (1, 2), all of which need to be provided with minerals and carbon sources….

Defects in 8-oxo-guanine repair pathway cause high frequency of C > A substitutions in neuroblastoma

Significance The collection of large amounts of whole-genome sequencing data allowed for identification of mutational signatures, which are characteristic combinations of substitutions in the context of neighboring bases. The clinical significance of these mutational signatures is still largely unknown. In neuroblastoma, we showed that high levels of cytosine > adenine…

Emergence of the Coexistence of mcr-1, blaNDM-5, and blaCTX-M-55 in Kl

Introduction Klebsiella pneumoniae (K. pneumoniae) is an opportunistic pathogen and the leading cause of healthcare-associated infections.1 Multidrug-resistant (MDR) K. pneumoniae isolates are rapidly spreading, thus limiting the choice of antimicrobial agents for empiric treatment of infections caused by these microorganisms; hence, this is a public health challenge.2 Polymyxins are last-resort…

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…

Genome-wide synthetic lethal screen unveils novel CAIX-NFS1/xCT axis as a targetable vulnerability in hypoxic solid tumors

Abstract The metabolic mechanisms involved in the survival of tumor cells within the hypoxic niche remain unclear. We carried out a synthetic lethal CRISPR screen to identify survival mechanisms governed by the tumor hypoxia–induced pH regulator carbonic anhydrase IX (CAIX). We identified a redox homeostasis network containing the iron-sulfur cluster…
