Cholesterogenic genes expression in brain and liver of ganglioside-deficient mice.

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
The aim of this study was to determine the effect of changed ganglioside profile on transcription of selected genes involved in cholesterol homeostasis. For that purpose, the expression of 11 genes related to cholesterol synthesis, regulation, and cholesterol transport was investigated in selected brain regions (frontal cortex, hippocampus, brain stem, cerebellum) and liver of St8sia1 knockout (KO) mice characterized by deficient synthesis of b- and c-series gangliosides and accumulation of a-series gangliosides. The expression of majority of the analyzed genes, as determined using quantitative real time PCR, was slightly higher in St8sia1 KO compared to wild-type (wt) controls. More prominent changes were observed in Hmgr, Cyp51, and Cyp46 expression in brain (hippocampus and brain stem) and Srebp1a, Insig2a, and Ldlr in liver. In addition, the expression of master transcriptional regulators, Srebp1a, Srebp1c, and Insig2a, as well as transporters Ldlr and Vldlr differed between liver and brain, and within brain regions in wt animals. Cyp46 expression was expectedly brain-specific, with brain region difference in both wt and St8sia1 KO. The established change in transcriptome of cholesterogenic genes is associated to specific alteration of ganglioside composition which indicates relationship between gangliosides and regulation of cholesterol metabolism.
