Activation of ATM-c-IAP1 Pathway Mediates the Protective Effects of Estradiol in Human Vascular Endothelial Cells Exposed to Intermittent Hypoxia.
Article in Nature and science of sleep, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeChronic intermittent hypoxia (CIH) contributes to the increased risk of cardiovascular diseases in obstructive sleep apnea (OSA). We previously reported the anti-apoptotic effects of estradiol (E2) on IH-exposed human umbilical vein endothelial cells (HUVECs). Herein, we employed a proteomic analysis to elucidate the mechanisms of the protective effects of E2 under IH exposure.
methodsHUVECs were divided into three groups: control, IH, and IH+E2 group. Isobaric tags for relative and absolute quantification (iTRAQ) were performed to compare protein profiles among the groups. Some of the identified proteins were validated by Western blotting.
resultsA total of 185 proteins were differentially expressed in the IH+E2 group compared to the IH group. Bioinformatics analysis indicated that the effects of E2 may be linked to the regulation of cellular stress response. Among the differentially expressed proteins, we identified that serine-protein kinase ataxia telangiectasia mutated (ATM) and its downstream target, cellular inhibitor of apoptosis protein 1 (c-IAP1), were up-regulated by E2. We also observed that E2 decreased the level of cleaved caspase-3 and inhibited cell apoptosis in IH-exposed HUVECs. The inhibition of ATM abolished the anti-apoptotic effect of E2.
conclusionThe ATM-c-IAP1 pathway is involved in the cardioprotective effects of E2 in HUVECs exposed to IH.
