Transforming growth factor-β1 (TGF-β1) is an important player in chronic liver diseases inducing fibrogenesis and hepatocellular carcinoma (HCC) development. TGF-β1 promotes pleiotropic modifications at the cellular and matrix microenvironment levels. TGF-β1 was described to enhance production of type I collagen and its associated cross-linking enzyme, the lysyl oxidase-like2 (LOXL2). In addition, TGF-β1 and type I collagen are potent inducers of invadosomes. Indeed, type I collagen fibers induce the formation of active linear invadosomes through the discoidin domain receptor 1 (DDR1)...

Osteoarthritis (OA) is the most common form of arthritis disorders, but the identification of therapeutic targets to effectively prevent OA has been increasingly difficult. The goal of this investigation is to provide experimental evidence that discoidin domain receptor 2 (DDR2) may be an ideal target for the development of disease-modifying OA drugs. Ddr2 was conditionally deleted from articular cartilage of adult mouse knee joints. Aggrecan-CreERT2;floxed Ddr2 mice, which were generated by crossing Aggrecan-CreERT2 mice with floxed Ddr2 mice, then received tamoxifen injections at the age of 8 weeks...

Pancreatic ductal adenocarcinomas (PDAC) are highly malignant cancers characterized by extensive invasion into surrounding tissues, metastasis to distant organs, and a limited response to therapy. A main feature of PDAC is desmoplasia, which leads to extensive deposition of collagen I. We have demonstrated that collagen I can induce epithelial-mesenchymal transition (EMT) in pancreatic cancer cells. A hallmark of EMT is an increase in the expression of the mesenchymal cadherin N-cadherin. Previously we showed up-regulation of N-cadherin promotes tumor cell invasion and collagen I-induced EMT is mediated by two collagen receptors, alpha2beta1-integrin and discoidin domain receptor 1 (DDR1)...

Increasing evidence has suggested that discoidin domain receptor 2 (DDR2) plays an important role in cancer development and metastasis. However, the correlation between DDR2 expression and clinical outcome in ovarian cancer has not been investigated. In this study, DDR2 expression was examined by Real-time PCR in surgically resected ovarian cancer and normal ovary tissues. Besides, DDR2 expression was analyzed immunohistochemically in 103 ovarian cancer patients, and the correlation between DDR2 expression with clinicopathologic factors was analyzed...

Effector T cell migration through the tissue extracellular matrix (ECM) is an important step of the adaptive immune response and in the development of inflammatory diseases. However, the mechanisms involved in this process are still poorly understood. In this study, we addressed the role of a collagen receptor, the discoidin domain receptor 1 (DDR1), in the migration of Th17 cells. We showed that the vast majority of human Th17 cells express DDR1 and that silencing DDR1 or using the blocking recombinant receptor DDR1:Fc significantly reduced their motility and invasion in three-dimensional (3D) collagen...

Insulin-like growth factor-I (IGF-I)/IGF-I receptor (IGF-IR) system has been largely involved in the pathogenesis and development of various tumors. We have previously demonstrated that IGF-IR cooperates with the G-protein estrogen receptor (GPER) and the collagen receptor discoidin domain 1 (DDR1) that are implicated in cancer progression. Here, we provide novel evidence regarding the molecular mechanisms through which IGF-I/IGF-IR signaling triggers a functional cross-talk with GPER and DDR1 in both mesothelioma and lung cancer cells...

Discoidin (DS) domains are found in eukaryotic and prokaryotic extracellular and transmembrane multidomain proteins. These small domains play different functional roles and can interact with phospholipids, glycans, and proteins, including collagens. DS domain-containing proteins are often involved in cellular adhesion, migration, proliferation, and matrix-remodeling events, while some play a major role in blood coagulation. Mutations in DS domains have been associated with various disease conditions. This review provides an update on the structure, function, and modulation of the DS domains, with a special emphasis on two circulating blood coagulation cofactors, factor V and factor VIII, and the transmembrane neuropilin receptors that have been targeted for inhibition by biologics and small chemical compounds...

Genetic screening identifies the atypical tetraspanin TM4SF1 as a strong mediator of metastatic reactivation of breast cancer. Intriguingly, TM4SF1 couples the collagen receptor tyrosine kinase DDR1 to the cortical adaptor syntenin 2 and, hence, to PKCα. The latter kinase phosphorylates and activates JAK2, leading to the activation of STAT3. This non-canonical mechanism of signaling induces the expression of SOX2 and NANOG; sustains the manifestation of cancer stem cell traits; and drives metastatic reactivation in the lung, bone, and brain...

Idiopathic pulmonary fibrosis (IPF) is a lethal human disease with short survival time and few treatment options. Herein, we demonstrated that discoidin domain receptor 2 (DDR2), a receptor tyrosine kinase that predominantly transduces signals from fibrillar collagens, plays a critical role in the induction of fibrosis and angiogenesis in the lung. In vitro cell studies showed that DDR2 can synergize the actions of both transforming growth factor (TGF)-β and fibrillar collagen to stimulate lung fibroblasts to undergo myofibroblastic changes and vascular endothelial growth factor (VEGF) expression...

The quantity and quality of collagen fibrils in the extracellular matrix (ECM) have a pivotal role in dictating biological processes. Several collagen-binding proteins (CBPs) are known to modulate collagen deposition and fibril diameter. However, limited studies exist on alterations in the fibril ultrastructure by CBPs. In this study, we elucidate how the collagen receptor, discoidin domain receptor 1 (DDR1) regulates the collagen content and ultrastructure in the adventitia of DDR1 knock-out (KO) mice. DDR1 KO mice exhibit increased collagen deposition as observed using Masson's trichrome...

Accumulation of type I collagen fibrils in tumors is associated with an increased risk of metastasis. We recently demonstrated that the collagen sensor discoidin domain receptor 1 (DDR1) interacts with type I collagen fibrils to allow proteolysis-based cancer cell invasion through the formation of a new class of invadosomes, termed linear invadosomes.

High levels of collagen deposition in human and mouse breast tumors are associated with poor outcome due to increased local invasion and distant metastases. Using a genetic approach, we show that, in mice, the action of the fibrillar collagen receptor discoidin domain receptor 2 (DDR2) in both tumor and tumor-stromal cells is critical for breast cancer metastasis yet does not affect primary tumor growth. In tumor cells, DDR2 in basal epithelial cells regulates the collective invasion of tumor organoids. In stromal cancer-associated fibroblasts (CAFs), DDR2 is critical for extracellular matrix production and the organization of collagen fibers...

The structure-based design of 1, 2, 3, 4-tetrahydroisoquinoline derivatives as selective DDR1 inhibitors is reported. One of the representative compounds, 6j, binds to DDR1 with a Kd value of 4.7 nM and suppresses its kinase activity with an IC50 value of 9.4 nM, but it is significantly less potent for a panel of 400 nonmutated kinases. 6j also demonstrated reasonable pharmacokinetic properties and a promising oral therapeutic effect in a bleomycin-induced mouse pulmonary fibrosis model.

This study reports how extracellular matrix (ECM) ligand self-assembly on biomaterial surfaces and the resulting nanoscale architecture can drive stem cell behavior. To isolate the biological effects of surface wettability on protein deposition, folding, and ligand activity, a polydimethylsiloxane (PDMS)-based platform was developed and characterized with the ability to tune wettability of elastomeric substrates with otherwise equivalent topology, ligand loading, and mechanical properties. Using this platform, markedly different assembly of covalently bound type I collagen monomers was observed depending on wettability, with hydrophobic substrates yielding a relatively rough layer of collagen aggregates compared to a smooth collagen layer on more hydrophilic substrates...

Tumor cells are confronted to a type I collagen rich environment which regulates cell proliferation and invasion. Biological aging has been associated with structural changes of type I collagen. Here, we address the effect of collagen aging on cell proliferation in a three-dimensional context (3D).We provide evidence for an inhibitory effect of adult collagen, but not of the old one, on proliferation of human fibrosarcoma HT-1080 cells. This effect involves both the activation of the tyrosine kinase Discoidin Domain Receptor 2 (DDR2) and the tyrosine phosphatase SHP-2...

Discoidin domain receptor I (DDR1) is confirmed as a receptor tyrosine kinase (RTK), which plays a consequential role in a variety of cancers. Nevertheless, the influence of DDR1 expression and development in renal clear cell carcinoma (RCCC) are still not well corroborated. In our research, we firstly discovered that the expression level of DDR1 was remarkable related to TNM stage (p = 0.032), depth of tumor invasion (p = 0.047), and lymph node metastasis (p = 0.034) in 119 RCCC tissue samples using tissue microarray...
