Abstract

The endometrium is prepared for implantation by the actions of estradiol (E2) and progesterone (P4). In mice the luminal epithelium (LE) only becomes fully receptive to the attaching blastocyst in response to the nidatory estrogen surge on d 4 of pregnancy. The cytokine leukemia-inhibitory factor (LIF) is rapidly induced by nidatory estrogen and has been shown to be the primary mediator of its action. Implantation fails in the absence of LIF, and injection of LIF on d 4 of pregnancy can substitute for the nidatory estrogen. In this study, we sought to identify genes regulated by LIF in the uterine epithelium. We used oligonucleotide microarrays to compare the transcript profiles of paired uterine horns from LIF-deficient MF1 mice after intraluminal injection of LIF or PBS on d 4 of pseudopregnancy. IGF-binding protein 3 was identified as a gene up-regulated by LIF; this was confirmed by RT-PCR. In situ hybridization showed that the primary site of IGF-binding protein 3 expression is the luminal epithelium (LE), the known site of LIF action in the uterus. We identified two other genes: amphiregulin and immune response gene-1, the expression of which were also up-regulated by LIF. Immune response gene 1 has recently been shown to be essential for implantation. Expression of all three of these genes in the LE is known to be regulated by P4. The expression of osteoblast-specific factor 2 and leukocyte 12/15 lipoxygenase, which are also expressed in LE under the control of P4, were not increased by LIF. This suggests that one of the actions of LIF on LE may be to enhance the expression of a subset of P4-regulated genes.

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.
