MicroRNA 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. We have employed Agilent Human MicroRNAs microarray platform to evaluate the expressions of 866 human miRNAs and 89 human viral miRNAs, based on Sanger miRNA database release 12.0

miRNA 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. We have employed Agilent Human MicroRNAs microarray platform to evaluate the expressions of 866 human miRNAs and 89 human viral miRNAs, based on Sanger miRNA database release 12.0.

miRNA Profiling from total blood of Multiple Sclerosis and control samples

Project description:This project aims at the detection of specific patterns of miRNAs in peripheral blood samples of MS patients. As controls, blood of donors without known affection have been tested. Using the miRNA patterns we hope to detect a diagnostic pattern for the non-invasive diagnosis of MS. In this study, we compared 20 Multiple Sclerosis samples to 21 control samples using the sanger miRBAse 12.0 miRNA biochip manufactured by febit. Samples were analyzed with the Geniom Realtime Analyzer (GRTA, febit gmbh, Heidelberg, Germany) using the Geniom Biochip miRNA homo sapiens. Each array contains 7 replicates of 866 miRNAs and miRNA star sequences as annotated in the Sanger miRBase 12.0. To benchmark the platform, we tested technical replicates using bought total RNA of brain and liver samples (ambion), achieving a correlation of 0.97.

Microarray analysis of the miRNA levels in plasma from healthy donors

Project description:To further understanding of mature microRNA in plasma from healthy people, we have employed microRNA microarray as a discovery platform with the potential to identify the plasma microRNA levels of healthy people. Human peripheral blood was drawn from 4 healthy donors, and plasma was obtained by two-step centrifugation. Equal of total RNA from the plasma was detected by microRNA microarray including 866 human and 89 human viral miRNAs (Sanger miRBase, release 12.0). About 170 miRNAs could be detected by microarray in all 4 samples of plasma. Among them, 6 microRNAs (miR-451, miR-16, miR-133a, miR-1, miR-499 and miR-208a) were detected in the RNA from the same plasma by real-time PCR. Freshly peripheral bloods from 4 healthy donors were drawn into EDTA tubes, and were processed within 1 hour by two-step centrifugation to remove the blood cells and the cellular debris. Small RNA was prepared using the mirVana PARIS kit, and was quantified using a NanoDrop-1000 spectrophotometer. Equal of RNA from the plasma was detected by microRNA microarray to identify the microRNAs levels in plasma of healthy people.

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.

Transcription profiling of human mammary epithelial cells HMECs in replicative senescence vs fibroblasts

Project description:Telomere shortening in populations of human mammary epithelial cells (HMECs) that survive early replicative arrest (M0) by the inactivation of p16INK4A during cell culture on plastic dishes leads to a state of permanent replicative arrest termed senescence. While culture of HMECs on feeder layers abrogates M0 and p16INK4A inactivation, progressive telomere attrition in these cells also eventually results in permanent replicative arrest. Expression of telomerase prevents both senescence on plastic (S-P) and senescence on feeder layers (S-FL) in HMECs, as it does also in cultured primary human fibroblasts. We report here that the gene expression profiles of senescence in HMECs of the same lineage maintained under different culture conditions showed surprisingly little commonality. Moreover, neither of these senescence-associated profiles in HMECs resembles the profile for senescence in human fibroblasts. These results indicate that senescence-associated alterations in gene expression resulting from telomere attrition are affected by culture conditions as well as by cell origins, and argue that replicative senescence at the molecular level is a diverse rather than unique cellular process.
