AIM Dilated cardiomyopathy (DCM) has a variety of causes, and no useful approach to predict left ventricular (LV) remodelling and long-term outcome has yet been established. Myocardial tenascin-C (TNC) is known to appear under pathological conditions, possibly to regulate cardiac remodelling. The aim of this study was to clarify the significance of myocardial TNC expression in LV remodelling an...

Extracellular matrix (ECM) molecules influence the ability of the central nervous system of adult mammals to regenerate after injury. The ECM component tenascin-C (TNC) can both promote and restrict neurite outgrowth in vitro and interact with growth factors and other ECM components. To evaluate the role of TNC in vivo, we anterogradely labeled corticospinal tract axons in wild-type (TNC+/+) an...

Thymic stromal cells play important roles in thymocyte differentiation and selection. Thymic nurse cells (TNC) are thymic epithelial stromal cells that envelop two to 200 CD4+CD8+ thymocytes (TNC-T). The mechanism by which TNC complexes form and their role in thymocyte development are unknown. TNC have been implicated as specialized microenvironments for proliferation, positive selection, negat...

BACKGROUND Pancreatic cancer (PDAC) is characterized by an abundant fibrous tissue rich in Tenascin-C (TNC), a large ECM glycoprotein mainly synthesized by pancreatic stellate cells (PSCs). In human pancreatic tissues, TNC expression increases in the progression from low-grade precursor lesions to invasive cancer. Aim of this study was the functional characterization of the effects of TNC on bi...

Tenascin-C (TNC) is a mechano-regulated, morphogenic, extracellular matrix protein that is associated with tissue remodeling. The physiological role of TNC remains unclear because transgenic mice engineered for a TNC deficiency, via a defect in TNC secretion, show no major pathologies. We hypothesized that TNC-deficient mice would demonstrate defects in the repair of damaged leg muscles, which ...

An important step in epithelial organ development is size maturation of the organ lumen to attain correct dimensions. Here we show that the regulated expression of Tenectin (Tnc) is critical to shape the Drosophila melanogaster hindgut tube. Tnc is a secreted protein that fills the embryonic hindgut lumen during tube diameter expansion. Inside the lumen, Tnc contributes to detectable O-Glycans ...

Multiple Sclerosis (MS) is an autoimmune disease, which is characterized by demyelination and neuroinflammation. Extracellular Matrix (ECM) have important role in the central nervous system (CNS). Alterations are happening to the ECM after the CNS disorder like MS, Alzheimer and other neural injury. Tenasin-C (TnC) is a glycoprotein that is highly expressed in inflammatory conditions of the CNS...

Neuropeptide S receptor 1 (NPSR1, GPRA 154, GPRA) has been verified as a susceptibility gene for asthma and related phenotypes. The ligand for NPSR1, Neuropeptide S (NPS), activates signalling through NPSR1 and microarray analysis has identified Tenascin C (TNC) as a target gene of NPS-NPSR1 signalling. TNC has previously been implicated as a risk gene for asthma. We aimed therefore to study th...

After a specific point in history, hominin evolution accelerated to level that could not be accounted for by natural selection alone. An alternative mechanism has been proposed based on mutual interaction among neural, cognitive, and ecological niches positive feedback loop (triadic niche construction [TNC]). Nevertheless, the trigger events cognitive revolution of Homo sapiens as well reasons ...
