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

Project description:Differential hyper- and hypo-methylation regions in G0 versus G4/G5 CMP The goal of this study is to evaluate changes in CpG methylation profilings of telomere dysfunctional common myeloid progenitor cells (CMP) as compared to their wild type controls Genomic DNA was extracted from sorted CMP populations isolated from 3 pools of G0 or 2 pools of G5 mice using UltraPure Phenol:Chloroform:Isoamyl Alcohol according to manufacturer’s instructions (Life Technologies). 14,000 to 30,000 cells were available for each sample, resulting in a minimum of 45ng of DNA. Genome-wide DNA methylation profiling was performed by RRBS. Library preparation and sequencing were performed at the UT MD Anderson Cancer Center’s DNA Methylation Analysis Core and Sequencing and Microarray Facility, according to published protocols. RRBS sequencing data were aligned and methylation was called using Bismark v0.7.119. In brief, bisulphite-treated DNA was aligned to UCSC Genome Browser mm10 reference genome using Bowtie. In total 29-38 million reads were generated per sample with alignment rates around 63%. Next, MethylKit10 implemented with Fisher’s exact test was used to compare the cytosine methylation profiles of G0 and G5 CMP. Gene promoter regions were calculated based on RefSeq gene annotations with regions starting 1 kb upstream of the annotated transcription start site (TSS) and extending 500 base pairs downstream of TSS. Exons, introns, and CpG islands coordinates were collected from the UCSC Genome Browser mm10 version.

Project description:The epigenetic regulation on gene transcription affected by Electronic-cigarette (E-cig) to human gingival mesenchymal (GMSC) is not fully understood. Here, we collected GMSCs from systemically healthy patients due to the premolars and extracted for orthodontic reasons, and treated with E-cig smoke with original flavor (G2), E-cig smoke with menthol flavor (G3), E-cig liquid with original flavor (G4), and E-cig liquid with menthol flavor (G5) by the optimal conditions of LC50, and conducted H3K27me3 ChIP-seq to compare with untreated control (G0).

Project description:The change of transcriptome and related biological functions affected by tobacco smoke and Electronic-cigarette (E-cig) to human gingival mesenchymal (GMSC) and periodontal ligament stem cells (PDLSCs) are not fully understood. Here, we collected GMSCs and PDLSCs from systemically healthy patients due to the premolars and extracted for orthodontic reasons, and treated with tobacco smoke (G1, P1), E-cig smoke with original flavor (G2, P2), E-cig smoke with menthol flavor (G3, P3), E-cig liquid with original flavor (G4, P4), and E-cig liquid with menthol flavor (G5, P5) by the optimal conditions of LC50, and conducted RNA-seq to compare with untreated control (G0, P0).
