Project description:Telomere dysfunctional CMP/GMP have deregulated pathways that are associated with DNA damage signaling We compared differentially expressed genes in the G4/G5 CMP relative to the G0 control to identify pathways that may affect CMP differentiation. Bone marrow CMP and GMP cells were sorted from two paired pools of G0 TERTER/+ or G4/G5 TERTER/ER mice (5,000-20,000 cells per sample) using the Influx Cell Sorter. Every paired pool includes CMP or GMP sorted from 4 age and gender matched G0 or G4/G5 mice. RNA from the respective sorted cells was extracted using Trizol (Ambion) and profiled on 2100 Bioanalyzer (Agilent). Gene expression profiling was performed at the Sequencing and Non-coding RNA Program at MD Anderson Cancer Center. Briefly, the GeneChip® 3 IVT Express Kit (Affymetrix) was used to generate biotin-labeled cRNA, which were purified and fragmented, before target hybridization on the GeneChip® Mouse Genome 430 2.0 Array (Affymetrix) according to the manufacturer's instructions. Affymetrix raw data (CEL files) were normalized using Affymetrix Microarray Suite (MAS) version 5.0 using a TGT=100. Paired pools used in the study were: CMP pool 1: G0-1 and G4/5-1 CMP pool 2: G0-2 and G4/G5-2 GMP pool 1: G0-1 and G4/G5-1 GMP pool 2: G0-2 and G4/G5-2

Umbilical cord blood methylome analysis of IVF neonates that underwent embryo culture in G5 or HTF medium

Project description:Follow-up study of IVF neonates who underwent embryo culture in G5 (Vitrolife) or HTF (Lonza) medium. Genome-wide DNA methylation profiling of IVF neonates (umbilical cord blood samples) who had undergone embryo culture in G5 medium (Vitrolife) or HTF medium (Lonza). The EPIC array was used to profile the methylome at approximately 850,000 CpG sites across the human genome.
