Abstract

Objectives We sought to assess tenascin-C (TN-C) expression and its possible pathobiological impact in human aortic valve stenosis.Background Tenascin-C, a large extracellular matrix glycoprotein, has lately been increasingly connected to cardiovascular pathologies. As TN-C is a multifunctional protein implicated in cell proliferation, migration and differentiation, we investigated the pattern of its expression in diseased human aortic valves.Methods Fifty-five tricuspid, non-rheumatic stenotic aortic valves were collected from patients undergoing aortic valve replacement, and the controls consisted of four normal valves from individuals who had suffered traumatic death and one from a patient operated on because of a noncalcified purely regurgitant valve. A monoclonal mouse antibody to human TN-C (143DB7) was used as the primary antibody in immunostaining. To study the source of TN-C messenger RNA synthesis, some tissue samples were also examined using in situ hybridization. In order to identify smooth muscle cell differentiation, commercially available antibodies against alpha-smooth muscle actin were used, and immunophenotypic analysis of inflammatory cells was carried out by using the monoclonal mouse antibodies UCHL-1, L26 and PGM-1.Results In normal valves, TN-C expression was associated with the basement membrane beneath the endothelial cells, whereas stenotic valves showed no such expression but rather immunoreactivity in the deeper layers of the valves. This reactivity was associated with the characteristics typical of the stenosing process and the increased mechanical loading caused by hypertension.Conclusions We hypothesize that the overexpression of TN-C in stenotic human aortic valves may emphasize that this disease is an active rather than a degenerative process.

  • Increased production of extracellular matrix components, including periostin, tenascin, and proteoglycans, contributes to aortic valve remodelling during aortic stenosis.

    “In addition, the increased production of several components of the extracellular matrix, including periostin, tenascin (also called tenascin-c) and proteoglycans contributes to the remodelling of the aortic valve during AS35;36.”

    From Calcific aortic stenosis (2016) · cites this paper as [36]

    The Immunohistochemistry of TN-C and cellular composition section (page not specified in our copy) reports increased tenascin-C mRNA expression in stenotic valves, supporting the tenascin-C part of the claim. The paper does not establish increased periostin or proteoglycan production, and its discussion proposes rather than demonstrates that tenascin-C contributes to valve changes. (LLM, conf=0.88)

  • Many of the most differentially expressed genes in severe forms of CAVS were previously reported in smaller studies.

    “As expected, many of the most differentially expressed genes in severe forms of CAVS were previously reported in smaller studies (PDK4, BTG2, SLC16A9, GPR68, FAP, CNTFR, PLEKHS1, THY1, SCG2, CXCL5, TNC, TDO2, LINC01614).9,12,13,28, 29, 30, 31, 32, 33”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
