Tao 2011, H3K4me3 in Lsh WT and Lsh-/- MEFs, GSE29393

Description

High-resolution cytosine methylation map of the murine genome modulated by Lsh, a chromatin remodeling family member that has previously been shown to regulate CpG methylation at repetitive sequences. Lsh also controls genome-wide cytosine methylation at nonrepeat sequences and relate those changes to alterations in H4K4me3 modification and gene expression.

Samples

From Mouse Jul. 2007 (NCBI37/mm9) Assembly

Filename Description Feature GEO-ID
1 H3K4me3_wt.sga MEF(Lsh+/+) H3K4me3 H3K4me3 GSM726806
2 H3K4me3_Lsh_ko.sga MEF(Lsh-/-) H3K4me3 H3K4me3 GSM726807

Technical Notes

The SGA files were gerenerated from GEO accessory text files provided in Eland export format. Mapped sequence reads with alignment scores lower than 10 were discared. The source genome coordidnates were remapped from mouse genome assembly Feb. 2006 (NCBI36/mm8) to July 2007 (NCBI37/mm9) using the liftOver software from UCSC.
