Role of ldb1 in adult intestinal homeostasis.
Article in International journal of biological sciences, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ldb1 is an essential co-regulator of transcription in embryonic development. It acts in conjunction with nuclear LIM-homeodomain and LIM-only proteins to control key events of organogenesis as precursor cells enter lineage specification. Here we ask whether Ldb1 exerts control over stem cell activation and differentiation throughout the life of the organism as required for tissue homeostasis. To help answer this question, we have generated conditional Ldb1 mouse mutants with an Ldb1 floxed/floxed;ROSA26CreER genotype. Tamoxifen treatment of 60 day-old mutant animals results in near-ubiquitous Cre-mediated Ldb1 inactivation. As a consequence, the stem cell microenvironment of intestinal crypts is drastically affected. Cells that normally express Ldb1 together with markers that identify them as lineage progenitors cease to retain bromodeoxyuridine and are gradually lost. Ldb1 inactivation in intestinal crypts and/or in neighboring mesenchymal cells also triggers activation of Wnt signaling in the stem cell niches of the small intestine. Cell proliferation is markedly increased in the epithelia of the small intestine, and Lgr5-expressing stem cells disappear from the base of the crypts. This perturbation of the normal process of tissue homeostasis causes apoptosis, and the animals do not survive. We conclude that Ldb1-mediated transcriptional regulation plays a major role in adult intestinal homeostasis.
