Gene signature of young and replicative senescent human umbilical vein endothelial cells (HUVECs)

ABSTRACT: MicroRNAs regulate various cellular processes. While several genes associated with replicative senescence have been described in endothelial cells, miRNAs that regulate these genes remain largely unknown. The present study was designed to identify miRNAs associated with replicative senescence and their target genes in HUVECs. Gene profiling was established using the same RNA input as that used for miRNA profiing. We have employed Agilent Whole Human Genome microarray platform to evaluate the expressions of 19,596 human genes .

Gene signature of young, replicative and TNF-α-induced premature senescent of human microvascular endothelial cells-lung (HMVEC-L)

Project description:Despite the fact that miRNAs have been extensively investigated for their involvement in diseases, senescence as well as inflammation, miRNAs involved in TNF-α- induced premature senescence remain to be uncovered. Hence, the present study aims to identify unique miRNAs and their respective signaling pathways in TNF-α-induced senescence in lung microvascular endothelial cells and novel targets for prevention or protection against premature senescence and endothelial hyperpermeability. Gene profiling was established using the same RNA input as that used for miRNA profiing. We have employed Agilent Whole Human Genome microarray platform to evaluate the expressions of 19,596 human genes.

Microarray analysis of Replicative senescence and TNF-α induced senescence in Human umbilical vein endothelial cells (HUVECs)

Project description:Cellular senescence is a dynamic tumor suppression mechanism that limits the proliferation of impaired cells, by executing a stable cell cycle arrest. Understanding the molecular pathways and regulatory circuits that are involved in the process of senescence is presently incomplete. In this study, we determined the changes in gene expression during the establishment of replicative senescence, by comparing the expression profiles of young and senescent human umbilical vein endothelial cells (HUVECs). Exploration of array data using ingenuity pathway analysis showed that genes involved in cell cycle regulation, cellular assembly and organization, DNA replication, recombination and repair were significantly down regulated during senescence.

RNA-seq of young and senescent human umbilical vein endothelial cells (HUVECs) under normal or high glucose conditions

Project description:Human endothelial cellular models are useful to disentangle the pathophysiological role of dysfunctional endothelium in the development of cardiovascular (CV) disease and organ damage in T2D. Here, we performed a RNAseq of human umbilical vein endothelial cells (HUVECs) undergoing replicative senescence and exposed to high glucose (25 mM) to investigate the combined effects of replicative senescence and high glucose on the transcriptional landscape of these cells. To gain insight into the molecular mechanisms driving the acquisition of a senescent phenotype following exposure to HG, we performed a RNA-seq assay on control (Ctr) and replicative senescent (Sen) HUVECs cultivated in presence/absence of HG culture medium (total number of samples = 12; number of samples in each cell type-medium condition group = 3) using the NovaSeq 6000 Illumina system. Differential expression analysis was performed in R environment (version 4.2.2) using the limma and edgeR Bioconductor R packages.

Cellular Senescence RT2 Profiler PCR Array of replicative senescent and hyperglycemia treated HUVECs

Project description:Young endothelial cells (CPD >25 and <30; SA-Beta Gal positivity <10%) were exposed to one week of hyperglycemia (25 mmol/L) or sub-cultured until complete growth arrest (CPD > 50). Using real-time PCR, we analyzed the expression of a focused panel of genes involved in cellular senescence.The array includes genes involved in the primary senescence program and known stresses that cause premature senescence.

DNA methylation profiles of human umbilical vein endothelial cells (HUVECs)

Project description:Replicative senescence has major impact on function and integrity of cell preparations. DNA-methylation (DNAm) changes are continuously acquired at specific CpG dinucleotides during in vitro culture. Such modifications can be used to estimate the state of cellular senescence for quality control of cell preparations. It is however unclear how senescence-associated DNAm changes are regulated and if they occur simultaneously throughout cell populations. In this study, we analyzed global DNAm profiles of human mesenchymal stem cells (MSCs) and human umbilical vein endothelial cells (HUVEC) to demonstrate that senescence-associated DNAm changes are overall similar in these different cell types. Subsequently, an Epigenetic-Senescence-Signature, based on six CpGs, was either analyzed by pyrosequencing or by barcoded bisulfite amplicon sequencing. There was a good correlation between predicted and real passage numbers in bulk populations of MSCs (R² = 0.67) and HUVECs (R² = 0.97).

Potential roles of DNA methylation in the initiation and establishment of replicative senescence revealed by array-based methylome and transcriptome analyses [methylation]

Project description:Cellular senescence is classified into two types; replicative and premature senescence. Gene expression and epigenetic changes are different in types of senescence, replicative and premature senescence, and cell types. Normal human diploid fibroblast TIG-3 cells were often used in cellular senescence research, however, their epigenetic profiles were not fully understood. To elucidate how cellular senescence is epigenetically regulated in TIG-3 cells, we analyzed gene expression and DNA methylation profiles among three types of senescent cells, namely, replicative senescent, RAS-induced senescent (RIS) and non-permissive temperature-induced senescent SVts8 cells, using gene expression and methylation microarrays. The expression of genes involved in cell cycle and immune response were commonly either down- or up-regulated among three types of senescent cells, respectively. The sequential alteration of DNA methylation level was observed only in replicative senescent cells in a time-dependent manner, but not in premature senescent cells. The integrated analysis of gene expression and methylation in replicative senescent cells demonstrated that the expression of 759 genes involved in cell cycle and immune response was associated with methylation. Furthermore, hypomethylation occurred at non-CpG island regions (open sea) on the genes with increased expression as well as non-CpG promoter of the genes related to immune response. Several miRNAs regulated by DNA methylation were found to affect the expression of their target genes. Taken together, these results indicate that DNA methylation contributes to introduction and establishment of replicative senescence partly by regulating gene expression.
