A new gene, SRP16, differentially expressed in the spermathecae of honeybee queens (Apis mellifera) related with reproduction status.

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
Honey bee queens have the ability to store sperm in spermathecae for fertilizing eggs throughout their life. To investigate mechanisms for sperm storage in Apis mellifera, we employed suppression subtractive hybridization (SSH) to find differentially expressed fragments in spermathecae between virgin queens and newly mated queens. A new gene, named SRP16, was obtained by joining the SSH products with 5'-RACE and 3'-RACE. SRP16 is predicted to encode a 41 kDa protein with 363 amino acid residues. Its expression was found in the spermathecae dominantly in honey bee queens but not in honey bee workers, with the highest expression found in spermathecae of virgin and newly mated queens. SRP16 expression was weak in other tissues of queens other than in the spermathecae and showed no obvious change with reproductive status of queens. The results suggest that SRP16 may play important roles in sperm storage and honey bee reproduction.
