Study: The prenatal nicotine exposure leads to epigenetic alterations in nervous system signaling genes in the rat [MeDIP]
show Abstracthide Abstract
Background. Prenatal exposure to nicotine has been documented to impose numerous deleterious effects on fetal development. However, the epigenetic changes promoted by nicotine exposure on germ cell are still not well understood. Objectives. In this study, we focused on elucidating the impact of prenatal nicotine exposure on regulatory epigenetic mechanisms important for the germ cells development. s important for the germ cells development Overall design: Sprague-Dawley rats were exposed to nicotine during pregnancy and male progeny was analyzed at age of 11 weeks. A genome-wide DNA methylation was analyzed using MEDIP-seq.
Sample: rat testis, MEDIP control 3

Name: GSM8023946
Instrument: NextSeq 2000
Strategy: MeDIP-Seq
Source: GENOMIC
Selection: 5-methylcytidine antibody
Layout: PAIRED
Construction protocol: DNA was extracted from 6 biological replicates using DNA Easy Blood and Tissue Kit (Qiagen, 69506) according to instructions provided by manufacturer. DNA concentration was measured by fluorescent method using fluorescent reader (Promega). 10 µgs of DNA was used for MeDIP using methylated DNA Enrichment Kit (NEB, #E2600S). DNA was diluted and sonicated in Qsonica sonicator using following conditions: 20 s pulse on, 20 sec pulses off, total sonication time is 8 min. After that, sonicated DNA was incubated with MBD2-Fc -protein A Magnetic beads. The beads were washed 4 times with 1XBind/Wash Buffer. The enriched methylated DNA was eluted from beads with miliQ water and and the concentration of methylated DNA was again determined by fluorescence. 6 ng of methylated DNA or input were taken for library preparation. Sequencing libraries were prepared using NEBNext Ultra DNA Library Prep Kit for Illumina (E7645S; NEB). We performed 15 cycles for the library amplification.
