Project description:SILAC analysis of human primary bladder smooth muscle cells treated with platelet-derived growth factor for 0, 4, and 24 h. Platelet-derived growth factor-BB (PDGF-BB) is a mitogen and motogen that has been implicated in the proliferation, migration and synthetic activities of smooth muscle cells (SMC) that characterize pathologic tissue remodeling in hollow organs. To explore the signals induced by PDGF on a global scale, we performed expression profiling and quantitative proteomics analysis of PDGF-treated human visceral SMC. 1695 genes and 241 proteins were identified as differentially expressed in PDGF-treated primary bladder SMC versus non-treated cells. Analysis of gene expression data revealed MYC, JUN, EGR1, MYB and RUNX1 as the transcription factors most significantly networked with upregulated genes; DDIT3, NFAT5, and SOX5 were most networked with downregulated genes. For protein identification and quantification, raw mass spectrometric data were analyzed with MaxQuant software (version 1.0.13.13). The parameters were set as follows. In the Quant module, SILAC triplets was selected; oxidation (M) and acetyl (Protein N-term) were set as variable modification; carbamidomethyl (C) was set as fixed modification; concatenated IPI human database (version 3.52) (74,190 forward sequences and 74,190 reverse sequences) was used for database searching; all other parameters were default. Tandem mass spectra were searched by Mascot (version 2.2.0.4) (Matrix Science, Boston, MA). In the Identify module, all parameters were default, except that maximal peptide posterior error probability was set as 0.05. False discovery rates for protein and peptide identifications were both set at 0.01.
Project description:Pulmonary artery smooth muscle cells were either mock transfected, transfected with scramble control or transfected with pre-miR-143. After 24 hours the cells were harvested with Qiazol and processed for a microarray experiment. The experiment was performed in order to identify potential targets of miR-143.
Project description:Analysis of miRNAs associated with NCL via RNA immunoprecipitation in pulmonary artery smooth muscle cells using NCL antibodies to identify a distinct set of miRNAs regulated by NCL. Results provide insight into the regulatory mechanism of RNA binding proteins in vascular smooth muscle cells.
Project description:Investigation of RBPMS role in post-transcriptional control of mRNAs in rat PAC1 pulmonary artery smooth muscle cells (SMCs). PolyA mRNA-Seq was carried out after RBPMS knockdown in differentiated PAC1 cells and after inducible RBPMS-A overexpression in dedifferentiated (proliferative) PAC1 cells.
