Project description:Human peripheral blood T cells (total CD3+) were stimulated for 12 and 24 h with plate bound CD3/CD28 or CD3/CD63 mAbs in the presence or absence of the D2-domain of the cytoplasmic tail of CD45. Total RNA was purified and gene expression profiles were obtained.

Project description:Integrins, the principal extracellular matrix (ECM) receptors of the cell, promote cell adhesion, migration, and proliferation, which are key events for cancer growth and metastasis. To date, most integrin-targeted cancer therapeutics have disrupted integrin-ECM interactions, which are viewed as critical for integrin functions. However, such agents have failed to improve cancer patient outcomes. We show that integrin b1, a highly expressed subunit in lung epithelium, is required for lung adenocarcinoma development in a carcinogen-induced mouse model. Likewise, human lung adenocarcinoma cell lines with integrin b1 deletion failed to form colonies in soft agar and tumors in mice. Mechanistically, we demonstrate that these effects do not require integrin b1-mediated adhesion to ECM but are dependent on integrin b1 cytoplasmic tail-mediated activation of focal adhesion kinase (FAK). Together, these studies support a critical role for integrin b1 in lung tumorigenesis that is mediated through constitutive, ECM-binding independent signaling involving the cytoplasmic tail.

Project description:Human p97/VCP is a vital AAA ATPase (ATPase associated with diverse cellular activity) plays critical roles in autophagy, endosomal trafficking, and the ubiquitin-proteasome system. Mutations in p97 cause inclusion body myopathy associated with paget’s disease of bone and frontotemporal dementia. P97 is overexpressed in several cancers. The selective active site inhibitor CB-5083 targets p97’s D2 domain and shows potential as an anti-cancer therapeutic, though it has faced clinical setbacks due to off-target effects. To investigate the protein levels changed of HL60 cells (acute myeloid leukemia cell line) by CB-5083 in cytoplasmic, nuclear, and insoluble membrane compartments, we employed fractionation and label-free proteomic analysis. Results reveal distinct compartment-specific protein regulation, providing insight into CB5083’s cellular mechanisms and potential for more targeted therapeutic applications.

Project description:The role of cells of the hematopoietic lineage in fibrosis is controversial. Here we evaluate the contribution of Col I+/CD45+ cells (fibrocytes) to lung fibrosis. Systemic bleomycin treatment was used to induce fibrosis in a bone marrow transplant and two transgenic mouse models. Lung cells from these mice were analyzed by flow cytometry, both immediately upon release from the tissue or following growth on tissue-culture plastic. Fibrotic and control human lung tissue were also used. Fibroblasts and fibrocytes derived from a transgenic mouse model were compared in terms of their morphology, growth, and adhesion to fibronectin. Single cell RNAseq was performed with the analysis focusing on CD45-/Col I+ “fibroblasts” and CD45+/Col I+ “fibrocytes” in control and fibrotic mouse lung tissue. Finally, we inhibited fibrosis in mice using a novel, water-soluble version of caveolin scaffolding domain (CSD) called WCSD.

Project description:TC-510 is a novel cell therapy that consists of autologous genetically engineered T cells expressing two synthetic constructs: first, a single-domain antibody that recognizes human Mesothelin, fused to the CD3-epsilon subunit which, upon expression, is incorporated into the endogenous T cell receptor (TCR) complex and second, a PD-1:CD28 switch receptor, which is expressed on the surface of the T cell, independently from the TCR. The PD-1:CD28 switch receptor comprises the PD-1 extracellular domain fused to the CD28 intracellular domain via a transmembrane domain. Thus, the switch is designed to produce a costimulatory signal upon engagement with PD-L1 on cancer cells.

Project description:ADAMs are transmembrane metalloproteases that control cell behavior by cleaving both cell adhesion and signaling molecules. The cytoplasmic domain of ADAMs can regulate the proteolytic activity by controlling the subcellular localization and/or the activation of the protease domain. Here we show that the cytoplasmic domain of ADAM13 is cleaved and translocates into the nucleus. Preventing this translocation renders the protein incapable of promoting cranial neural crest (CNC) cell migration in vivo, without affecting its proteolytic activity. In addition, the cytoplasmic domain of ADAM13 regulates the expression of multiple genes in the CNC. This study shows that the cytoplasmic domain of ADAM metalloproteases can perform essential functions in the nucleus of cells and may contribute substantially to the overall function of the protein.

Project description:Kindlin-1, -2, and -3, directly bind integrin β cytoplasmic tails to regulate integrin activation and signaling. Despite their functional significance and link to several diseases, structural information on full-length kindlin proteins remains unknown. Here, we report the crystal structure of human full-length kindlin-3, which reveals a novel homotrimer state. Unlike kindlin-3 monomer, which is the major population in insect and mammalian cell expression systems, kindlin-3 trimer does not bind integrin β cytoplasmic tail as the integrin-binding pocket in the F3 sub-domain of one protomer is occluded by the PH domain of another protomer, suggesting that kindlin-3 is auto-inhibited upon trimer formation. This is also supported by functional assays in which kindlin-3 knockout K562 erythroleukemia cells re-constituted with the mutant kindlin-3 containing trimer-disrupting mutations exhibited an increase in integrin-mediated adhesion and spreading on fibronectin compared to those re-constituted with wild type kindlin-3. Taken together, our findings reveal a novel mechanism of kindlin auto-inhibition that involves its homotrimer formation.

Total RNA from cranial neural crest explants dissected from Xenopus laevis embryos at stage 15 to 17. Embryos were injected with either control morpholino (CMO), morpholino to ADAM13 (MO13) or MO13 and a fusion between GFP- and the cytoplasmic domain of ADAM13 (GFP-C13). Triplicate microarray correspond to independent experiments labeled DA4, DA5 and DA2. For each sample 1 is CMO, sample 2 is MO13 and sample 3 is MO13+C13. Embryos were injected with 10 ng of morpholino and 0.5 ng of GFP-C13 mRNA. Supplementary files: [1] matrix2_sig-genes.txt CNC array: Genes significantly affected by the loss of ADAM13 p<0.01.
