The ENmix DNA methylation analysis pipeline for Illumina BeadChip and comparisons with seven other preprocessing pipelines | Clinical Epigenetics

Methylation analysis pipelines The ENmix pipeline performs data preprocessing in a stepwise way, including ENmix background correction [1], RELIC dye bias correction [3], optional inter-array normalization, RCP probe-type bias correction [2], quality control, filtering of low-quality data points, and imputation. ENmix background correction employs a mixture of exponential and truncated…

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…
