Project description:This work determined the POH1 regulated genes in the absence or presence of TGF-β in SMMC-7721 cells through genome-wide transcriptome sequencing.
Project description:Expression profiling in hippocampal neurons to identify activity-regulated genes controlled by MEF2; Experiments were conducted to identify activity-regulated MEF2 target genes. Experiment Overall Design: Neurons were depolarized with 55mM extracellular KCl for one or six hours in the presence of control or MEF2-specific shRNAs
Project description:RATIONALE: Studying the genes expressed in samples of tissue from patients with cancer may help doctors identify biomarkers related to cancer.
PURPOSE: This laboratory study is using gene expression profiling to evaluate normal tissue and tumor tissue from patients with colon cancer that has spread to the liver, lungs, or peritoneum.
Project description:Here, by combining transcriptome and proteome profiling, we identified 228 post-transcriptionally regulated genes with strict regulation at the protein level in PSCs. Among them, 84 genes were found necessary for the survival of several cell types including PSCs, and 20 genes were identified as specific for the survival of PSCs. These 20 proteins were upregulated only in PSCs and not in differentiated cells derived from the three germ layers. Subcellular fractionation of the mRNA showed that the expression level of most of the 20 proteins was regulated at the mRNA localization stage from the nucleus to the cytoplasm in PSCs, but their translation efficiency was unchanged compared with other cell types. Together, these results reveal a critical function of post-transcriptionally regulated genes on PSC survival.
