Project description:To clarify the mechanism of Efp/TRIM25 in breast cancer, breast cancer cells (MDA-MB-231 and TNBC-PDC) were transfected with siRNAs targeting Efp (siEfp_1 and siEfp_3) and control siRNA targeting firefly luciferase (siCont). We used microarrays to detail the global programme of Efp-mediated gene expression and identified up- and down-regulated genes.
Project description:To examine the role of Efp in endometrial cancer cells, Ishikawa and HEC-1A cells were treated with siRNA targeting Efp (siEfp) or control siRNA (siControl). Microarray analysis showed that Efp knockdown represses NF-κB-signaling pathway-associated genes.
Project description:To examine the role of Efp in endometrial cancer, patient-derived cells were treated with siRNA targeting Efp (siEfp) or control siRNA (siControl). siRNA-mediated Efp silencing resulted in suppressed spheroid proliferation and altered gene expression profile, featuring downregulation of genes related to cell cycle and inflammation/immune responses. This study provides an insight into alternative endometrial cancer therapeutic strategies targeting Efp.
Project description:Ribosome profiling is a powerful method for globally assessing the activity of ribosomes in a cell. Despite its application in many organisms, ribosome profiling studies in bacteria have struggled to obtain the resolution necessary to precisely define translational pauses. Here we report improvements that yield much higher resolution in E. coli profiling data, enabling us to more accurately assess ribosome pausing and refine earlier studies of the impact of polyproline motifs on elongation. We comprehensively characterize pausing at proline-rich motifs in the absence of elongation factor EFP. We find that only a small fraction of genes with strong pausing motifs have reduced ribosome density downstream and identify features that explain this phenomenon. These features allow us to predict which proteins likely have reduced output in the efp knockout strain. Ribosome profiling of E. coli MG1655 and mutants lacking EFP or its three modifiying enzymes
Project description:We used MYOSIN10 shRNA to stably silence the expression of endogenous MYOSIN10 in Breast cancer cell MDA-MB-231. To investigate the inner change of cells with silenced MYOSIN10, we conducted a genome-wide screening for all potential genes affected by MYOSIN10 shRNA using Affymetrix Human Genome U133 plus 2.0 array. We showed genes affected by MYOSIN10 knockdown in breast cancer cell MDA-MB-231
