Project description:To examine the role of the TGF-beta/Smad3 pathway in cardiac damage by doxorubicin, we performed comparitive RNA sequencing analysis of cardiac endothelial cells isolated from WT and Smad3 knockout mice.
Project description:To examine the role of the TGF-beta/Smad3 pathway in cardiac damage by doxorubicin, we performed comparitive RNA sequencing analysis of human cardiac endothelial cells transfected with Smad3 shRNA
Project description:A knockout clone has been generated for both FAM50A and FAM50B; knockout of the other gene is then performed and the transcriptome is analysed to look at the effect of dual gene loss.
Project description:smad3 is the central component of TGF-beta pathway. We examined the role of Smad3 in ES cell differentiation and teratoma formation. In this data set, we include expression data from Smad3 knockout ES cell and wild type ES cells.
Project description:To measure the immunosuppressive effect of caspase-3 and -7 in apoptosis, we generated B16 sgCTRL and sgCasp3/7 cells and treated them with doxorubicin
Project description:Doxorubicin as a commonly used anthracycline has become the cornerstone of chemotherapy in a wide range of cancers owing to its high efficacy. However, clinical applications of doxorubicin are limited mainly due to its toxic effects on myocardium but the pathogenic mechanism of doxorubicin-induced cardiomyopathy are poorly understood. ADAM17 is known as tumor necrosis factor α converting enzyme (TACE), and the cleavage of TNF-α by ADAM17 is a prerequisite for pro-inflammatory TNF-α activity, which raises a possibility that inhibition of ADAM17 may exert a beneficial effect on disease processes where TNF-α plays an essential role. Our previous research has shown that cardiomyocyte specific knockout of ADAM17 improves diabetic cardiomyopathy by modulating cardiomyocyte apoptosis. However, the relationship between ADAM17 and doxorubicin-induced cardiomyopathy is unclear.Through RNA sequencing analysis, we observed significant changes in the TNF signaling pathway genes in the heart tissue of mice with or without cardiomyocyte ADAM17 knockout.
Project description:Gene expression profiling was carried out in six (wild type, β2SP+/-, β2SP-/-, SMAD3+/-, SMAD3-/- and β2SP+/-/ SMAD3+/-) different mouse knockout embryonic fibroblast (MEF) cells. Beta-2-spectrin (β2SP) is a dynamic intracellular non-pleckstrin homology (PH)-domain protein that belongs to a family of polypeptides that have been implicated in conferring cell polarity. Spectrins have been linked to multiple signaling pathways, including cell cycle regulation, DNA repair and TGFβ signaling. In this study, we report a major role of the TGFβ/Smad3 adaptor β2-Spectrin in conserving genomic integrity from alcohol-induced DNA damage and describe a novel pathway that protects genomes from genotoxic stresses. To determine the mechanism for the oncogenic switch, and whether it is related to the role of β2SP in TGF-β signaling transduction or secondary to its cytoskeletal functions, we analyzed disruption of two elements of the TGF-β pathway by generating double heterozygous Sptbn1+/−/Smad3+/− mice.
