Abstract

Klotho mutant mice exhibit a set of phenotypes resembling human ageing. Although the function of Klotho remains unclear, mediation of its pleiotropic functions by putative humoral factor(s) has been presumed. Newly established antibodies against Klotho allowed the detection of secreted Klotho, a candidate for the putative humoral factor, in sera and cerebrospinal fluid. Surprisingly the secreted Klotho was 130 kDa, in contrast to the 70 kDa predicted form from klotho gene transcripts. The secreted as well as the membrane‐bound Klotho proteins were suggested to form oligomerized complex. These results delineate post‐translation processing of Klotho and possible regulatory mechanisms for secretion of Klotho in vivo.

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.
