Project description:Chondrocytes can potentially perceive mechanical stimuli via Piezo channels. We investigated the effect of the Piezo1 agonist Yoda1 on chondrocyte-like ATDC5 cells. Chondrocytes can potentially perceive mechanical stimuli via Piezo channels. We investigated the effect of the Piezo1 agonist Yoda1 on chondrocyte-like ATDC5 cells. Chondrocytes can potentially perceive mechanical stimuli via Piezo channels. We investigated the effect of the Piezo1 agonist Yoda1 on chondrocyte-like ATDC5 cells. Chondrocytes can potentially perceive mechanical stimuli via Piezo channels. We investigated the effect of the Piezo1 agonist Yoda1 on chondrocyte-like ATDC5 cells. We used microarray analysis to detail the global gene expression of ATDC5 cells in response to 6 hours of treatment with 5µM Yoda1.
Project description:Limb development is a well-established model for understanding cell fate decisions, and the formation of skeletal elements is coordinated through a sequence of events that control chondrogenesis spatiotemporally. It has been established that epigenetic control participates in cartilage maturation. Our research has shown for the first time that the inhibition of DNA methylation in interdigital tissue with 5-azacytidine results in the formation of an ectopic digit. This discovery suggested that DNA methylation dynamics could regulate the fate of cells between chondrogenesis and cell death during autopod development. We sequenced WGBS libraries from in-vivo interdigital tissue treated with 5-azacytidine or DMSO to identify genome-wide methylation changes during the early stages of 5-azacytidine-induced chondrogenesis.
Project description:We performed genome-wide transcriptome profiling in stable Kmt2d-/- (bi-allelic deletion of the catalytic SET domain) and Kmt2d+/+ ATDC5 chondrocyte cell lines 7 days after induction of differentiation and in stable Kmt2d-/- and Kmt2d+/+ undifferentiated ATDC5 cells.
Project description:Five SAGE libraries were generated from A. thaliana leaf tissue collected at time points ranging from 30 minutes to one week of low temperature treatment (4°C). Over 240,000 high quality SAGE tags, corresponding to 16,629 annotated genes, provided a comprehensive survey of changes in the transcriptome in response to low temperature, from perception of the stress to acquisition of freezing tolerance. Keywords: SAGE; time course; stress response; cold acclimation; freezing tolerance
