Project description:Alpha-parvin (PARVA) is known to involve in the linkage of integrins, regulation of actin cytoskeleton dynamics, and cell survival. However, the role of PARVA in cancer progress is still unclear. Here, we identify PARVA as a potential oncogene from a lung cancer invasion cell line model by expression microarrays. Overexpression of PARVA enhances cell invasion, colony formation ability, and endothelial cell tube formation but knockdown of PARVA inhibits invasion and tube formation in vitro. PARVA also promotes tumorigenicity, angiogenesis, metastasis and mortality by in vivo tumorigenesis and metastasis mouse models. To explore the underlying mechanism, the PARVA-regulated signaling pathways were analyzed in PARVA-overexpressing cells compare with mock controls by expression microarrays. We used microarrays to profile the global gene expression of PARVA-overexpressing cells compared with mock control cells and identified the pathways involved in PARVA-induced biofunctional alterations.
Project description:Podocyte specific knockout mice for Parva (Parva-fl/fl*hNPHS2Cre) were generated. Transcriptome profiling (RNA-Seq) and differential gene expression analysis of isolated renal glomeruli from KO and WT mice was performed. Parva KO mice showed transcriptional changes associated with podocyte and glomerular disease.
