Comethyl: a network-based methylome approach to investigate the multivariate nature of health and disease

This article was originally published here Brief Bioinform. 2022 Jan 17:bbab554. doi: 10.1093/bib/bbab554. Online ahead of print. ABSTRACT Health outcomes are frequently shaped by difficult to dissect inter-relationships between biological, behavioral, social and environmental factors. DNA methylation patterns reflect such multivariate intersections, providing a rich source of novel biomarkers and…

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…

An intronic transposon insertion associates with a trans-species color polymorphism in Midas cichlid fishes

Conflicting results suggest a missing variant In order to narrow down candidates for the causal genetic variant, we performed genome-wide association mapping separately in individual lake populations (previously, association mapping was only performed across the whole species flock5). Interestingly, despite clear association peaks in the crater lakes (Fig. 1a, b), the…

RedChIP identifies noncoding RNAs associated with genomic sites occupied by Polycomb and CTCF proteins

Abstract Nuclear noncoding RNAs (ncRNAs) are key regulators of gene expression and chromatin organization. The progress in studying nuclear ncRNAs depends on the ability to identify the genome-wide spectrum of contacts of ncRNAs with chromatin. To address this question, a panel of RNA–DNA proximity ligation techniques has been developed. However,…

Parallel genomic responses to historical climate change and high elevation in East Asian songbirds

Extreme environments present profound physiological stress. The adaptation of closely related species to these environments is likely to invoke congruent genetic responses resulting in similar physiological and/or morphological adaptations, a process termed “parallel evolution” (1). Existing evidence shows that parallel evolution is more common at the phenotypic level than at…

High-purity production and precise editing of DNA base editing ribonucleoproteins

Abstract Ribonucleoprotein (RNP) complex–mediated base editing is expected to be greatly beneficial because of its reduced off-target effects compared to plasmid- or viral vector–mediated gene editing, especially in therapeutic applications. However, production of recombinant cytosine base editors (CBEs) or adenine base editors (ABEs) with ample yield and high purity in…

An epigenetic basis of inbreeding depression in maize

INTRODUCTION Charles R. Darwin documented inbreeding depression as growth disadvantages from self-fertilization compared to outcrossing in many plants (1). Prevailing hypotheses suggest that inbreeding depression results from the exposure of deleterious recessive alleles and/or loss of overdominant alleles due to increased homozygosity (2, 3) or reduced recombination frequency in some…

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…

Nature Papers Present 3D Maps of Single-Cell DNA Organization, Structure of Conserved SARS-CoV-2 Element, More

Aiming to address the technical challenges of measuring three-dimensional genome organization at the single-cell level, a group of California Institute of Technology researchers has developed a method to generate high-resolution, genome-wide maps of 3D DNA organization in thousands of individual cells. The approach — called single-cell split-pool recognition of interactions…

Could amino acid finding from Cambridge scientists help predict our personal risk of common diseases?

Inside our cells are mitochondria, which act as their powerhouses – generating about 90 per cent of the energy required for the biochemical reactions required for them to function. This is just one of the vital biological functions of these organelles, which are unique in having their own genetic code….

Pericentromeric noncoding RNA changes DNA binding of CTCF and inflammatory gene expression in senescence and cancer

Significance During the aging process, senescent cells secrete inflammatory factors, causing various age-related pathologies. Thus, controlling the senescence-associated secretory phenotype (SASP) can tremendously benefit human health. Although SASP seems to be induced by the alteration of chromosomal organization, its underlying mechanism remains unclear. Here, it has been revealed that noncoding…
