Intracerebral hemorrhage alters α2δ1 and thrombospondin expression in rats.
Article in Experimental and therapeutic medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Calcium voltage-gated channel auxiliary subunit (α2δ1) is a non-essential subunit of the voltage-gated calcium channel complex and is ubiquitously expressed in a number of tissues, including the brain. Thrombospondin (TSP)1 and TSP2 are extracellular matrix proteins and belong to the multi-domain glycoprotein family of macromolecular oligomers. TSP1/2 and α2δ1 promote synapse formation and functional recovery following cerebral infarction. However, to the best of our knowledge, the expression levels of α2δ1 and TSP1/2 in brain tissues, and the effects of intracerebral hemorrhage (ICH) on these levels have not yet been elucidated. The present study established a rat model of hemorrhage induced by injecting collagenase IV into the striatum to determine the changes in α2δ1 and TSP1/2 expression following ICH. The protein expression levels of α2δ1 and TSP1 in the striatum after hemorrhage were significantly increased on day 5 and returned to baseline levels on day 21; however, the protein expression levels of TSP2 were decreased on day 5, whereas they increased on day 14, subsequently returning to baseline levels. In addition, using proteomics analysis of tissues from the sham group (saline injection) and at 24 h post-ICH, it was found that both α2δ1 and TSP1 interacted with neural EGFL like 2. Taken together, these findings suggested that the expression levels of α2δ1 and TSP1/2 were altered in brain tissues in response to ICH.
