Phosphorylation of alphaB-crystallin in epiretinal membrane of human proliferative diabetic retinopathy.
Article in International journal of ophthalmology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
aimTo examine phosphorylation of alphaB-crystallin (p-αBC), a vascular endothelial growth factor (VEGF) chaperone, and immunohistochemically investigate relationship between p-αBC, VEGF and phosphorylated p38-mitogen-activated protein kinase (p-p38 MAPK) in the epiretinal membrane of human proliferative diabetic retinopathy (PDR).
methodsEleven epiretinal membranes of PDR surgically excised were included in this study. Two normal retinas were also collected from enucleation tissues due to choroidal melanoma. Paraformaldehyde-fixed, paraffin-embedded tissue sections were processed for immunohistochemistry with anti-p-αBC, VEGF, CD31, and p-p38 MAPK antibodies.
resultsImmunoreactivity for p-αBC was observed in all of the epiretinal membranes examined, where phosphorylation on serine (Ser) 59 showed strongest immunoreactivity in over 70% of the membranes. The immunolocalization of p-αBC was detected in the CD31-positive endothelial cells, and co-localized with VEGF and p-p38 MAPK in PDR membranes. Immunoreactivity for p-αBC, however, was undetectable in endothelial cells of the normal retinas, where p-p38 MAPK immunoreactivity was less marked than PDR membranes.
conclusionPhosphorylation of αBC, in particular, phosphorylation on Ser59 by p-p38 MAPK may play a potential role as a molecular chaperon for VEGF in the pathogenesis of epiretinal membranes in PDR.
