Ectopic overexpression of haem oxygenase-1 protects kidneys from carboplatin-mediated apoptosis.
Article in British journal of pharmacology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
background and purposeWe previously reported that the activation of the nuclear factor of activated T-lymphocyte-3 (NFAT3) by carboplatin leads to renal apoptosis as a result of oxidative stress, which is reversed by N-acetylcysteine. Herein, we extend our previous work to provide evidence of the molecular mechanisms of haem oxygenase (HO)-1 in protecting against injury. EXPERIMENTAL APPROACH: Protective mechanisms of HO-1 in carboplatin-mediated renal apoptosis were examined in C57BL/6 mice and rat renal tubular cells (RTC) with HO-1 induction or inactivation/knockdown. KEY
resultsThe HO-1, induced by cobalt protoporphyrin, protected against carboplatin-induced renal injury in vivo. This protection was decreased by an inhibitor of HO-1 action, tin protoporphyrin. In cultures of RTC, carboplatin-induced apoptosis was similarly affected by HO-1 overexpression or knockdown. Carboplatin-mediated NFAT3 activation and apoptosis involve activation of the signalling kinases, extracellular signal regulated kinase, Jun N-terminal kinase and protein kinase C, and such activation was reversed in cells overexpressing HO-1. Both products of the HO-1 reaction, CO and bilirubin, inhibited (by 30-40%) NFAT3 activation and production of the pro-apoptotic proteins Bcl-XS/Bax. Additionally, the activation of NFκB was markedly decreased by HO-1 induction. CONCLUSION AND IMPLICATIONS: HO-1 and its reaction products show anti-apoptotic effects in carboplatin-mediated renal injury. A novel functional NFAT3 binding site identified in the rat HO-1 promoter region was involved in producing a 1.5-fold to 2.5-fold increase in HO-1 induction by carboplatin. Nevertheless, only HO-1 overexpression and activation prior to the carboplatin challenge provided protection against carboplatin-induced injury.
