Alterations in the expression of the anti-apoptotic factor HAX-1 upon seizures-induced hippocampal injury in the neonatal rat brain.

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
HS1-associated protein X1 (HAX-1) is a mitochondrial protein which interacts with a diverse group of molecules such as inflammatory cytokines; interleukin-1, hematopoietic lineage specific protein-1 and vimentin. It has been reported that HAX-1 may act as antiapoptotic protein in HeLa- and Jurkat cells after Fas-treatment, irradiation or serum deprivation. This underlines the evidence that HAX-1 might be involved in both receptor- and mitochondria-mediated apoptosis pathways. However, the role of HAX-1 in neuronal death induced by status epilepticus in the immature brain has not been reported. In this study, we performed a status epilepticus in rats and investigated the dynamic changes of HAX-1 expression, HtrA2 distribution and caspase-3 activation in the hippocampus. Western blot and immunohistochemistry analysis revealed that HAX-1 was expressed at very low levels in the hippocampus. Status epilepticus in the immature brain significantly induced increased cytosolic accumulation of HAX-1 in a biphasic manner, induced an upregulation of HtrA2 and enhanced caspase-3 activity in the selectively vulnerable hippocampal CA1-subfield. Taken together, these results suggested that HAX-1 is probably involved in the pathophysiology of cell death induced by epilepsy.
