1 · What the graph read from it

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.

2 · The registry

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

backgroundIt is well established that reactive astrocytes express L-type calcium channels (LTCC), but their functional role is completely unknown. We have recently shown that reactive astrocytes highly express the CaV1.2 α1-subunit around β-amyloid (Aβ) plaques in an Alzheimer mouse model. The aim of the present study was to explore whether Aβ peptides may regulate the mRNA expression of all LTCC subunits in primary mouse astrocytes in culture.

methodsConfluent primary astrocytes were incubated with 10 µg/ml of human or murine Aβ or the toxic fragment Aβ25-35 for 3 days or for 3 weeks. The LTCC subunits were determined by quantitative RT-PCR.

resultsOur data show that murine Aβ42 slightly but significantly increased CaV1.2 and CaV1.3 expression when incubated for 3 days. This acute treatment with murine Aβ enhanced β2 and β3 mRNA levels but decreased α2δ-2 mRNA expression. When astrocytes were incubated for 3 weeks, the levels of CaV1.2 α1 were significantly decreased by the murine Aβ and the toxic fragment. As a control, the protein kinase C-ε activator DCP-LA displayed a decrease in CaV2.1 expression.

conclusionIn conclusion, our data show that Aβ can differentially regulate LTCC expression in primary mouse astrocytes depending on incubation time.
