Project description:Ezrin, an actin-binding protein, plays a crucial role in organizing the cellular cortical cytoskeleton and plasma membrane during cell migration, adhesion, and proliferation. While there is a good understanding of ezrin's function in cell types such as epithelial cells and lymphocytes, its role in monocytes/macrophages (MΦs) is less understood. Here, we used a monocyte/MΦ-specific ezrin knock-out mouse model to investigate the contribution of ezrin to monocyte recruitment and adaptation to the lung extracellular matrix (ECM) in response to lipopolysaccharide (LPS). Our study revealed that LPS induces ezrin expression in monocytes/MΦs, and that ezrin is essential for monocytes to adhere to lung ECM, proliferate, and differentiate into tissue-resident interstitial MΦs. Notably, ezrin is not required for monocyte extravasation into the lung parenchyma. Mechanistically, the loss of ezrin in monocytes disrupts activation of FAK and AKT signaling, which are necessary for lung-recruited monocytes and monocyte-derived MΦs to adhere to the ECM, proliferate, and survive. In summary, our data suggest that ezrin plays a role beyond structural cellular support, influencing diverse monocytes/MΦ processes and signaling pathways in response to infections, driving their adaptation to the lung microenvironment.

In summary, our data show that ezrin plays a role beyond structural cellular support, influencing diverse monocytes/MΦ processes and signaling pathways during inflammation, facilitating their differentiation into tissue-resident macrophages.

Project description:Ezrin (EZR), a cell membrane to cytoskeleton linker protein, plays key roles in maintaining cellular homeostasis. Its deregulation at various levels strongly correlates with cancer progression, metastasis and higher patient mortality. However, the precise mechanistic basis for its role remains unknown. Recently, we demonstrated that Ezrin participates in EGFR/AKT signaling pathways. Importantly, transitions between active (phosphorylated open) and inactive (dephosphorylated closed) forms of Ezrin is crucial for its function in cancer. Gene expression analysis suggested dysregulation of genes that are functionally linked to cell energetic metabolism with potential implications for cell proliferation, survival and apoptosis. Total RNA was extracted from n=4 for each experimantal group: Transcriptomic analysis was performed on HeLa WT and HeLa Ezrin KO cells.

Project description:It has been shown that up regulation activity of CD81(TAPA-1, the portal of entry of Hepatitis C virus) by agonistic antibody results in phosphorylation of Ezrin. We have previously shown that in liver, Ezrin phosphorylation occurs via Syk kinase, causing suppression of hippo intensity, therefore increases sequential Yap activity. The opposite occurs when Glypican-3 (GPC3) or E2 protein of HCV bind to CD81. Mice over-expressing GPC3 in hepatocytes have decreased p-Ezrin(Thr567) and Yap, increased Hippo activity and suppressed liver regeneration. The role of Ezrin in these processes has been speculated, but not proven. We now provide dynamic picture of Ezrin regulates Hippo pathway and Yap. Forced expression of plasmids expressing mutant Ezrin (T567D) (which mimics p-Ezrin(Thr567)) suppressed Hippo activity and activated Yap signaling. And this mutant Ezrin drive more cell proliferation to cell division through up regulated Yap activity in vitro and in vivo. CD81 loses expression, while p-Ezrin(Thr567) increases in JM1 and JM2 hepatocellular carcinoma (HCC) cells. Administration with compound NSC668394, a characterized p-Ezrin(Thr567) antagonist, caused significant decrease in HCC cell proliferation. We additionally present evidence that pEzrin(T567) is also controlled by EGFR and MET. Conclusions: Ezrin phosphorylation, mediated by CD81 associated Syk kinase, is directly involved in regulation of Hippo pathway, Yap levels and growth rates of normal and neoplastic hepatocytes. The finding has mechanistic and potentially therapeutic applications in understanding and regulating growth of hepatocytes and HCC and HCV pathogenesis. We used microarrays to detail the global programme of gene expression in GFP positive hepatocytes of FVB mice adminstration with EzrinT567D plasmids

Project description:Ezrin belongs to the ezrin¨Cradixin¨Cmoesin (ERM) family proteins, which cross-link actin cytoskeleton and plasma membrane, and is actively involved in regulating the growth and metastatic capacity of cancer cells. Esophageal squamous cell carcinoma (ESCC) is one of the most fatal malignancies in the world and the expression of ezrin in ESCC has been described only recently, but its roles and mechanism still remained unclear. we have used the pSUPER RNAi system to stably suppress the expression of the ezrin gene in EC109, an esophageal squamous carcinoma cell line, and then cDNA microarray was performed to explore some changed genes with ezrin silence. Keywords: Gene expression after RNAi
