Effects of Empagliflozin on Intermittent Hypoxia-Induced TRAF3IP2-Dependent Human Aortic Smooth Muscle Cell Proliferation.
Article in Medical research archives, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Aims: Chronic intermittent hypoxia (IH), a characteristic feature of obstructive sleep apnea (OSA), contributes to cardiovascular diseases, including atherosclerosis, potentially through persistent oxidative stress and inflammation. TRAF3IP2 (TRAF3 Interacting Protein 2) is an oxidative stress-responsive proinflammatory adapter molecule and plays a causal role in a preclinical model of atherosclerosis. Since SGLT2 (Sodium/Glucose Cotransporter 2) inhibitors have shown protective effects in CVD by inhibiting oxidative stress and inflammation, we hypothesized that IH promotes the crosstalk between oxidative stress and TRAF3IP2, resulting in IL-6-dependent human aortic smooth muscle cell (SMC) proliferation, and that these effects are inhibited by the SGLT2 inhibitor empagliflozin. Materials and methods: Primary human aortic SMC were exposed to various cycles of IH. Normoxia served as a control. To understand the molecular mechanisms underlying IH-induced nitroxidative stress, TRAF3IP2 and IL-6 induction, and SMC proliferation and those targeted by empagliflozin were determined by treating SMC with various pharmacological inhibitors and viral vectors. Results: IH upregulated TRAF3IP2 expression, TRAF3IP2-dependent superoxide, hydrogen peroxide and nitric oxide generation, NF-κB and HIF-1α activation, IL-6 induction, and SMC proliferation. Exposure to IL-6 by itself induced SMC proliferation in part via TRAF3IP2, IL-6R, gp130, JAK, and STAT3. Further, SMC express SGLT2 at basal conditions, and is upregulated by both IH and IL-6. Importantly, empagliflozin inhibited IH-induced TRAF3IP2 upregulation, reactive oxygen and nitrogen species generation, TRAF3IP2-dependent HIF-1α and NF-κB activation, IL-6 induction, and IL-6-dependent JAK-STAT3-mediated SMC proliferation. Moreover, empagliflozin inhibited IL-6-induced STAT3-dependent SMC proliferation. Conclusions: These results suggest the therapeutic potential of empagliflozin in IH and inflammatory vascular proliferative diseases associated with OSA.
