PURPOSE This study investigated the effects of loss of tenascin C (TNC) in the development of neovascularization in a corneal stroma in mice. Cell culture study was also conducted to clarify the roles of TNC in the expression of vascular endothelial growth factor (VEGF) and transforming growth factor (TGF)β1 in fibroblasts and macrophages. METHODS Ocular fibroblasts and macrophages from wild-...
The extracellular matrix glycoprotein tenascin-C (TNC) has been implicated in neural development and plasticity but many of its functions in vivo remain obscure. Here we addressed the question as to whether the constitutive absence of TNC in mice affects cortical physiology and structure. Defined major cell populations (neurons and inhibitory neuronal subpopulations, astrocytes, oligodendrocyte...
PURPOSE Our study is performed to find out clinicopathlogic and immunohistochemical (IHC) characteristics of triple negative invasive lobular carcinoma (ILC), as has been demonstrated in their invasive ductal counterparts. MATERIALS AND METHODS Retrospective analysis of variable clinicopathlogic parameters and IHC stains for androgen receptor, estrogen receptor, progesterone receptor, p53, c-...
EPR of spin labeled TnC at Cys98 was used to explore the possible structural coupling between TnC in the thin filament and myosin trapped in the intermediate states of ATPase cycle. Weakly attached myosin heads (trapped by low ionic strength, low temperature and ATP) did not induce structural changes in TnC as compared to relaxed muscle, as spin labeled TnC displayed the same narrow orientation...
INTRODUCTION The aim of this study was to examine whether circulating levels of the pro-inflammatory glycoprotein tenascin-C (TNC) are elevated in musculoskeletal disorders including rheumatoid arthritis (RA) and to assess in RA whether levels are related to clinical disease status and/or patient response to treatment. METHODS TNC in serum or plasma was quantified by ELISA. Samples from 4 coh...
Here, we present mechanisms for the inhibition of oligodendendrocyte precursor cell (OPC) differentiation, a biological function of neural extracellular matrix (ECM). The differentiation of oligodendrocytes is orchestrated by a complex set of stimuli. In the present study, we investigated the signaling pathway elicited by the ECM glycoprotein tenascin C (Tnc). Tnc substrates inhibit myelin basi...
Tenascin-C (TNC), a large extracellular matrix glycoprotein, has been reported to be associated with metastasis and poor prognosis in pancreatic cancer. However, the effects and mechanisms of TNC in pancreatic cancer metastasis largely remain unclear. We performed Transwell assays to investigate the effects of TNC on Capan-2, AsPC-1 and PANC-1 cells. In addition, western blot and RT-qPCR assays...
The extracellular matrix molecule tenascin-C (TNC) is a major component of the cancer-specific matrix, and high TNC expression is linked to poor prognosis in several cancers. To provide a comprehensive understanding of TNC's functions in cancer, we established an immune-competent transgenic mouse model of pancreatic β-cell carcinogenesis with varying levels of TNC expression and compared stocha...
We have isolated a full length complementary DNA clone (pCTnC1) from a 19-day embryonic chicken heart library corresponding to cardiac troponin C (TnC). Sequence analysis demonstrated varying homologies with TnC complementary DNA clones isolated from developing chick skeletal muscle. Using pCTnC1 as a hybridization probe, we have determined that cardiac TnC is constitutively expressed in both a...
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...
