Butyrate and acetyl‐carnitine inhibit the cytogenetic expression of the fragile X in vitro

Pomponi, Maria Grazia, Neri, Giovanni·1994·American Journal of Medical Genetics

Abstract

Cytogenetic expression of the fragile site at Xq27.3 is only found in those patients who have a full mutation of the FMR1 gene, i.e., a large amplification of the CGG repeat. However, an expansion of this repeat, although necessary, does not seem to be sufficient to cause expression of fra (X)(q27.3). Other factors are clearly needed, e.g., thymidylate stress. Little or no attention has been paid to the possible role of histones in the expression of the fragile sites, in spite of their structural and regulatory role in the chromatin complex. Histones can be modified by treating intact cells in vitro with butyrate, a substance that causes histone acetylation. The purpose of the present work is to test the effect of butyrate and of the acetylating compound acetyl‐L‐carnitine on the expression of fra (X)(q27.3) by treating peripheral lymphocytes of fragile X syndrome patients with these substances in vitro. we show that this treatment causes a significant inhibition of fra (X)(q27.3) expression. © 1994 Wiley‐Liss, Inc.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Acetyl-l-carnitine inhibits cytogenetic expression of the fragile X site in patient-derived cultured lymphocytes.

    “Acetyl-l-carnitine (Nicetile, a natural compound improving cell metabolism), shown to inhibit cytogenetic expression of the fragile X site in patient-derived cultured lymphocytes (98), was administered to boys with FXS (99).”

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.
