Dissecting the pet18 mutation in Saccharomyces cerevisiae: HTL1 encodes a 7-kDa polypeptide that interacts with components of the RSC complex.

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 yeast pet18 mutant exhibits three distinct phenotypes: temperature-sensitive lethality, failure to maintain a dsRNA virus, and respiration deficiency. We have isolated a yeast mutant, H53, with phenotypes identical to those of pet18. Based on PCR and Southern hybridization analysis, H53 was found to result from a large chromosomal deletion extending from YCR019w to YCR028c on chromosome III. Genetic analysis was carried out on H53 to correlate individual loci with each of the observed phenotypes. Disruption of YCR020c-a/MAK31 brought about a loss of dsRNA without affecting the temperature sensitive phenotype. The loss of YCR020w-b/HTL1, which encodes a hypothetical protein of 78 amino acids in length, was shown to be responsible for the temperature-sensitive lethality of the H53 mutant. Using immunoblotting, we demonstrated that a 7-kDa protein was indeed expressed in wild-type yeast, but not in a HTL1 deletion mutant. Moreover, the significance of HTL1 was investigated by isolating genes that are functionally associated with HTL1. We demonstrated that Rsc8p interacts physically with Htl1p, and that the genes RSC3, STH1 and RSC30 interact with HTL1. Thus, HTL1 may play a role in the function of the RSC complex.
