Tfm Lac: A second isolation of testicular feminization in mice

Politch, J. A., Fox, T. O., Houben, P., Bullock, L., Lovell, D.·1988·Biochemical Genetics

Abstract

TfmLac, a new occurrence of the X-linked mutation testicular feminization, has been isolated in a stock of mice and mapped to the same region as the original TfmH mutation. We compared these two mutants to determine if there are differences in their putative residual androgen receptors or androgen responsiveness. Such differences have been reported for Tfm mutations in humans. We found no evidence for induction of ornithine decarboxylase (ODC) activity in TfmLac despite androgen treatment for up to 3 weeks. This is in agreement with findings for TfmH. Both of these mutants expressed small amounts of androgen binding activity which shared some properties with the normal androgen receptors in mouse kidney. The binding was distinguishable between the two mutants, however, as determined by hormone saturation experiments utilizing DNA-cellulose chromatography. These findings confirm the independence of the two mutations and are consistent with their being allelic: both result in severe deficits of androgen binding and response.

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.
