NODULIN HOMEOBOX is required for heterochromatin homeostasis in Arabidopsis

NDX is a heterochromatin-associated factor To understand the genome-wide regulatory roles of NDX, we first analyzed its genomic distribution. For this, we performed chromatin immunoprecipitation sequencing (ChIP-seq) in 10-day old Arabidopsis seedlings expressing N-terminally and C-terminally tagged NDX fusion proteins (flag-NDX/ndx1-1(FRI)/flc-2 and NDX-GFP/ndx1-1(FRI)/flc-2, respectively) expressed from their endogenous promoter21,32. The…

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…

DMRs, how common are they and how long?

DMRs, how common are they and how long? 1 Hi! Does anyone know how common differentially methylated regions (DMRs) (or just methylated regions) are? Say, in a 10,000bp region how many DMRs can one expect? Also, does anyone know about the distribution of the size/length of DMRs, i.e. how many…

Placenta has clues for an early diagnosis of ASD

The researchers of the‘UC Davis MIND during their research they used the genomic sequencing to find a DNA methylation signature in the placenta of infants diagnosed with autism. This hallmark has been linked to early fetal neurodevelopment. Thanks to this study, a new human gene linked to fetal brain development…

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.,…

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…

Integrated bioinformatics analysis to identify abnormal CC

Introduction In recent years, the morbidity and mortality of colon cancer have increased rapidly, both being ranked fourth worldwide. Although surgery-based comprehensive treatments improve the prognosis of colon cancer, because of the lack of available means for early diagnosis, the mortality level remains high for patients with advanced-stage cancer. The…
