Over-expression of HSPA12B protects mice against myocardium ischemic/reperfusion injury through a PPARγ-dependent PI3K/Akt/eNOS pathway.
Article in American journal of translational research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 4 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
Acute myocardial ischemia/reperfusion (MIR) injury leads to severe arrhythmias and a high lethality. We aim to determine the effect of heat shock protein A12B (HSPA12B), a newly discovered member of the Hsp70 family, on heart injury parameters following MIR surgery. We used HSPA12B transgenic mice to determine its effects on heart function parameters, infarct size and cellular apoptosis following MIR surgery. Proinflammatory cytokines, oxidative products and anti-oxidative enzymes in the myocardium were measured to evaluate the anti-inflammatory and anti-oxidative effects of HSPA12B over-expression. The role of PPARs/eNOS/PI3k/Akt pathway was investigated using their inhibitors. The alteration of hemodynamic parameters, histopathological, apoptotic and infarct size caused by MIR was greatly attenuated in HSPA12B over-expressed mice. HSPA12B also greatly mitigated the inflammatory response, demonstrated by the decrease in the levels of IL-1β, IL-6, TNF-a and MPO. Anti-oxidative enzymes (SOD, Catalase and GPx) were restored by HSPA12B; oxidative products (8-OHdG, MDA and protein carbonyl) were decreased. HSPA12B activated the PPARγ-dependent eNOS/PI3k/Akt pathway, and the influence of HSPA12B on cardiac function was reversed by the inhibitors of eNOS, PPARγ, Akt and PI3K. Our results present a novel signaling mechanism that HSPA12B protects MIR injury through a PPARγ-dependent PI3K/Akt/eNOS pathway.
