Loss of cadherin-11 in atherosclerosis immune response: altered macrophage migration and T cell activation

Project description:The objective of this study was to understand the impact of losing cadherin-11 (CDH11) on the immune response in atherosclerosis. CDH11 has previously been demonstrated to be associated with a number of fibrotic diseases, but its exact role in inflammation remains relatively unknown. In vivo models of atherosclerosis demonstrated altered immune cell profiles with CDH11-deficiency, including decreased circulating myeloid cell populations. In vitro studies of CDH11-deficient macrophages revealed increased expression of genes associated with migration, despite a functional decrease in migration, possibly due to compensatory mechanisms. RNAseq analysis also showed increased expression of MHC class II molecule genes in CDH11-/- macrophages, indicating that loss of CDH11 in macrophages could alter T cell populations through increased activation of CD4+ helper T cells. These results together indicate that CDH11 can alter the immune response, in part by impairing macrophage migration and by affecting T cell activation.

Cadherin-11 depletion in aggressive MDA-MB-231 breast cancer cells.

Project description:Cadherin-11 expression is associated with tumor progression and metastasis in various cancers, including basal-like breast carcinoma and advanced prostate cancer, and invasive cell lines, yet is absent in normal epithelium. We now show cadherin-11 attenuation in aggressive breast and prostate cancer cells results in marked decreases in proliferation, migration, and invasion. Cadherin-11 depletion in MDA-231 cells prevents tumor growth in mice and alters gene expression associated with poor prognosis malignancies. Additionally, a novel small molecule inhibitor targeting its unique adhesive interface significantly inhibits the growth and migration of cadherin-11 positive cells. Cadherin-11 is essential for malignant progression of MDA-231 basal-type cells, and may serve as both an aggressive tumor marker and viable therapeutic target for poor prognosis carcinomas expressing it.

VE-cadherin is essential for trophoblast migration and endovascular invasion

Project description:Vascular endothelial (VE-)cadherin is a homotypic adhesion protein that is expressed selectively by ECs in which it enables formation of tight vessels and regulation of vascular permeability. Since VE-cadherin is also strongly expressed in placental trophoblasts, it is a prime candidate for a molecular mechanism of vascular mimicry by those cells. Here, we show that the VE-cadherin is required for trophoblast migration and endovascular invasion into the maternal decidua. VE-cadherin deficiency results in loss of spiral artery remodeling due to a lack of invasive trophoblasts, leading to decreased flow of maternal blood into the placenta, fetal growth retardation and death. Loss of trophoblast invasion prevents decidualization, extracellular matrix remodeling, and immune cell clearance. These studies identify VE-cadherin as essential for trophoblast migration and coordination of decidual changes during endovascular invasion. They further suggest endothelial proteins such as VE-cadherin that are expressed by trophoblasts may play functionally distinct roles that do not simply mimic those in ECs.

Macrophage DCLK1 promotes atherosclerosis via binding to IKKβ and inducing inflammatory responses

Project description:Atherosclerosis is a chronic inflammatory disease with high morbidity and mortality rates worldwide. Doublecortin-like kinase 1 (DCLK1), a microtubule-associated protein kinase, is involved in neurogenesis and human cancers. However, the role of DCLK1 in atherosclerosis remains undefined. In this study, we identified up-regulated DCLK1 in macrophages in atherosclerotic lesions of ApoE-/- mice fed an HFD and determined that macrophage-specific DCLK1 deletion attenuates atherosclerosis by reducing inflammation in mice. Mechanistically, RNA sequencing analysis indicated that DCLK1 mediates oxLDL-induced inflammation via NF-κB signaling pathway in primary macrophages. Co-immunoprecipitation followed by LC-MS/MS analysis identified IKKβ as a binding protein of DCLK1. We confirmed that DCLK1 directly interacts with IKKβ and phosphorylates IKKβ at S177/181, thereby facilitating subsequent NF-κB activation and inflammatory gene expression in macrophages. Finally, a pharmacological inhibitor of DCLK1 prevents atherosclerotic progression and inflammation both in vitro and in vivo. Our findings demonstrated that macrophage DCLK1 promotes inflammatory atherosclerosis by binding to IKKβ and activating IKKβ/NF-κB. This study reports DCLK1 as a new IKKβ regulator in inflammation and a potential therapeutic target for inflammatory atherosclerosis.

Expression profile of PC-3-derived cell lines after transendothelial migration

Project description:Metastatic colonization involves cancer cell lodgment or adherence in the microvasculature and subsequent migration of those cells across the endothelium into a secondary organ site. To study this process further, we analyzed transendothelial migration of human PC-3 prostate cancer cells in vitro. We isolated a subpopulation of cells, TEM4-18, that crossed an endothelial barrier more efficiently, but surprisingly, were less invasive than parental PC-3 cells in other contexts in vitro. Importantly, TEM4-18 cells were more aggressive than PC-3 cells in a murine metastatic colonization model. Microarray and FACS analysis of these cells showed that the expression of many genes previously associated with leukocyte trafficking and cancer cell extravasation were either unchanged or down-regulated. TEM4-18 cells exhibited characteristic molecular markers of an epithelial-to-mesenchymal transition (EMT), including frank loss of E-cadherin expression and upregulation of the E-cadherin repressor ZEB1. Silencing ZEB1 in TEM4-18 cells resulted in increased E-cadherin and reduced transendothelial migration. TEM4-18 cells also express N-cadherin, which was found to be necessary, but not sufficient for increased transendothelial migration. Our results extend the role of EMT in metastasis to transendothelial migration and implicate ZEB1 and N-cadherin in this process in prostate cancer cells.

Oct4 affects E-cadherin expression via regulating Rnd1 associated cytoskeleton rearrangement in breast cancer cells

Project description:Oct4, a key transcription factor for maintaining the pluripotency and self-renewal of stem cells has been reported previously. It also plays an important role in tumor proliferation and apoptosis, but the role of Oct4 been in tumor metastasis is still not very clear. Here, we found that ectopic expression of Oct4 in breast cancer cells can inhibit their migration and invasion. Detailed examinations revealed that Oct4 up-regulates expression of E-cadherin, indicative of its inhibitory role in epithelial-mesenchymal transition (EMT). RNA-sequence assay showed that Oct4 down-regulates expression of Rnd1. As an atypical Rho protein, Rnd1 can affect cytoskeleton rearrangement and regulate cadherin-based cell-cell adhesion by antagonizing the typical Rho protein, RhoA. Ectopic expression of Rnd1 in MDA-MB-231 cells changes cell morphology which influences cell adhesion and increases migration. It is reported that EMT is accompanied by cytoskeleton remodeling, we hypothesized that Rnd1 may play a role in regulating EMT. Over-expression of Rnd1 can partly rescue the inhibitory effects induced by Oct4, not only migration and invasion, but also in E-cadherin level and cellular morphology. Furthermore, silencing of Rnd1 can up-regulate the expression of E-cadherin in MDA-MB-231 cells. These results present evidence that ectopic expression of Oct4 increases E-cadherin and inhibits metastasis, effects which may be related to Rnd1 associated cell-cell adhesion in breast cancer cells.
