Generating a knockdown transgene against Drosophila heterochromatic Tim17b gene encoding mitochondrial translocase subunit.
Article in PloS one, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Heterochromatic regions of eukaryotic genomes contain multiple functional elements involved in chromosomal dynamics, as well as multiple housekeeping genes. Cytological and molecular peculiarities of heterochromatic loci complicate genetic studies based on standard approaches developed using euchromatic genes. Here, we report the development of an RNAi-based knockdown transgenic construct and red fluorescent reporter transgene for a small gene, Tim17b, which localizes in constitutive heterochromatin of Drosophila melanogaster third chromosome and encodes a mitochondrial translocase subunit. We demonstrate that Tim17b protein is required strictly for protein delivery to mitochondrial matrix. Knockdown of Tim17b completely disrupts functions of the mitochondrial translocase complex. Using fluorescent recovery after photobleaching assay, we show that Tim17b protein has a very stable localization in the membranes of the mitochondrial network and that its exchange rate is close to zero when compared with soluble proteins of mitochondrial matrix. These results confirm that we have developed comprehensive tools to study functions of heterochromatic Tim17b gene.
