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

Rett syndrome (RTT), the second most common cause of mental retardation in females, has been associated with mutations in MeCP2, the archetypical member of the methyl-CpG binding domain (MBD) family of proteins. MeCP2 additionally possesses a transcriptional repression domain (TRD). We have compared the gene expression profiles of RTT- and normal female-derived lymphoblastoid cells by using cDNA microarrays. Clustering analysis allowed the classification of RTT patients according to the localization of the MeCP2 mutation (MBD or TRD) and those with clinically diagnosed RTT but without detectable MeCP2 mutations. Numerous genes were observed to be overexpressed in RTT patients compared with control samples, including excellent candidate genes for neurodevelopmental disease. Chromatin immunoprecipitation analysis confirmed that binding of MeCP2 to corresponding promoter CpG islands was lost in RTT-derived cells harboring a mutation in the region of the MECP2 gene encoding the MBD. Bisulfite genomic sequencing demonstrated that the majority of MeCP2 binding occurred in DNA sequences with methylation-associated silencing. Most importantly, the finding that these genes are also methylated and bound by MeCP2 in neuron-related cells suggests a role in this neurodevelopmental disease. Our results provide new data of the underlying mechanisms of RTT and unveil novel targets of MeCP2-mediated gene repression.
