Changes in aquaporins mRNA expression and liquid storage at 17°C: A potential biomarker of boar sperm quality?
Article in Reproduction in domestic animals = Zuchthygiene, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Artificial insemination (AI) for pigs relies on liquid storage of extended semen at 17°C, which preserves sperm quality and ensures its fertilizing capacity. Routine quality controls include the evaluation of sperm motility, viability and capacitation status. The physiological functions of all these features depend on transmembrane aquaporins (AQPs), proteins playing key roles in osmoadaptation. In this study, we made a relative quantification, using RT-qPCR, of the mRNA of several sperm AQPs in AI-liquid semen doses before and after a 48-hr incubation period, aiming to determine possible quantitative compromising expression changes during the process that could serve as a diagnostic tool. Our results showed a decrease in classical sperm motility variables (total and progressive motility and velocity) and sperm viability after 48-hr storage, whereas capacitation status increased overtime. mRNA expression increased in the orthodox AQP4 and AQP6 after 48-hr incubation, relative to control (0 hr) and 24-hr time-points. Moreover, mRNA expression of aquaglyceroporins AQP3, AQP7 and AQP10 was higher after 48-hr incubation, confirmed by AQP7-protein validation using Western blot. Our results indicate that expression levels of AQPs-mRNA can change in ejaculated pig spermatozoa under conditions of ex-vivo incubation that could modify sperm homeostasis, suggesting it could eventually become a relevant molecular biomarker to assess the efficiency of liquid storage of pig semen.
