Project description:We have developed Whole Genome Bisulfite Sequencing (WGBS) of a newborn and a centenarian to address the epigenetic drifts in human aging, which might be an alternative pathway to explain the age-associated alterations. In addition, we have analyzed the methylome of a middle-age donor (26 years). Examination of two DNA methylomes at the most extreme points of their lives to see differences that might contribute to explain the aged phenotype. The methylome of a middle-age donor (26 years) was also analyzed.
Project description:Examination of two DNA methylomes at the most extreme points of their lives to see differences that might contribute to explain the aged phenotype We have performed Whole Genome Bisulfite Sequencing (WGBS) and methylation array technology of newborn and a centenarian samples to address the Epigenetic drifts in Human aging, which might be an alternative pathway to explain the age-associated alterations. In addition, we used SNP array platforms to exclude an influence of copy number changes with age and SNPs on the identification of differentially methylated regions. This Series represents the methylation array data. The WGBS data are available in GSE31263.
Project description:SPO11-promoted DNA double-strand breaks (DSBs) formation is a crucial step for meiotic recombination, and it is indispensable to detect the broken DNA ends accurately for dissecting the molecular mechanisms behind. Here, we report a novel technique, named DEtail-seq (DNA End tailing followed by sequencing), that can directly and quantitatively capture the meiotic DSB 3’ overhang hotspots at single-nucleotide resolution.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
