Project description:Malignant melanoma might develop from melanocytic nevi in which the growth-arrested state has been broken. We analyzed the gene expression of young and senescent human melanocytes in culture. In this dataset we include the expression data of young and senescent human melanocytes.
Project description:LncRNAs and mRNAs expression profile of MEFs comparing senescent cells with young cells. The microarray with coverage of 41597 mouse lncRNAs and 35291 mouse mRNAs. In the study presented here, six samples were analyzed. Biological replicates: three Senescent MEFs, three Young MEFs, independently grown and harvested.
Project description:We utilized whole genome sequencing of mRNA (RNA-seq) to understand the extent to which the senescence-associated secretory phenotype is regulated by p38MAPK Examination of replicates of young, senescent or p38MAPK-inhibited senescent BJ human foreskin fibroblasts.
Project description:Senescence occurs in a programmed manner to dismantle the vegetative tissues and redirect the nutrients towards metabolic pathways supporting reproductive success. External factors can trigger the senescence program as an adaptive strategy, indicating that this terminal program is controlled at different levels. Using bisulphite conversion followed by sequencing, we interrogated changes in the methylome of senescent Arabidopsis leaves induced by darkness, and their impact on gene and transposable element (TE) expression with transcriptome sequencing. Two biological replicates were sequenced for each condition: S as senescent and NS as non senescent.
Project description:Cytokinins are plant hormones with biological functions ranging from coordination of plant growth and development to the regulation of senescence. A series of 2-chloro-N6-(halogenobenzylamino)purine ribosides was prepared and tested for cytokinin activity in selected bioassays. Several compounds showed significant activity, especially in delaying senescence in detached wheat leaves. We used microarrays to gather information about the reprogramming of gene transcription when senescent Arabidopsis leaves were treated with selected C2-substituted aromatic cytokinin ribosides that showed high activity in the senescence bioassay. Arabidopsis senescent leaves were treated with cytokinins and subsequently used for RNA extraction and hybridization on Affymetrix microarrays. 21-days old Arabidopsis leaves were treated with the appropriate cytokinin or left untreated (DMSO only).
Project description:We carried out the analysis using human skin fibrobllast HCA2 (MJ90) cells. Cells were indcued to be senescent cells by treatment with RO3306 and Nutlin3a. The transcriptome analysis between young cells (uniduced cells) nd senescent cells revealed lonrf2, a ubiqutin E3 ligase, is one of the genes highly expressed in senescnet cells.
