1 · What the graph read from it

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.

2 · The registry

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

Among the multiple cellular effects mediated by lysophosphatidic acid (LPA), the effect on cell proliferation has extensively been investigated. A recent study showed that LPA-mediated proliferation of colon cancer cells requires activation of beta-catenin. However, the majority of colon cancer cells have deregulation of the Wnt/beta-catenin pathway. This prompted us to hypothesize the presence of additional pathway(s) activated by LPA resulting in an increase in the proliferation of colon cancer cells. Krüppel-like factor 5 (KLF5) is a transcriptional factor highly expressed in the crypt compartment of the intestinal epithelium. In this work, we investigated a role of KLF5 in LPA-mediated proliferation. We show that LPA stimulated the expression levels of KLF5 mRNA and protein in colon cancer cells and this stimulation was mediated by LPA(2) and LPA(3). Silencing of KLF5 expression by small interfering RNA significantly attenuated LPA-mediated proliferation of SW480 and HCT116 cells. LPA-mediated KLF5 induction was partially blocked by inhibition of the mitogen-activated protein kinase kinase and protein kinase C-delta. Moreover, we observed that LPA regulates KLF5 expression via eukaryotic elongation factor 2 kinase (eEF2k). Inhibition of calmodulin or silencing of eEF2k blocked the stimulation in KLF5 expression. Knockdown of eEF2k specifically inhibited KLF5 induction by LPA but not by fetal bovine serum or phorbol 12-myristate 13-acetate. These results identify KLF5 as a target of LPA-mediated signaling and suggest a role of KLF5 in promoting proliferation of intestinal epithelia in response to LPA.
