Evaluation of aptamers binding ability towards bovine X-specific sperm.
Article in Molecular biology reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSemen sexing is a much sought-after technique in the livestock industry. Current research focuses on selecting DNA aptamers (Synthetic single-stranded DNA) against X-sorted sperm. METHODS AND
resultsFour rounds of Cell-SELEX were performed, where the DNA aptamer library was incubated with X-sorted semen. Subsequently, affinity-depicting aptamers were sequenced. Fourteen out of thirty-four identified sequences were tested for specificity towards X-sorted sperm. The magnetic bead-based experiment revealed that the aptamers interacted preferentially with the acrosome region (sperm head) of sperm. We investigated the specificity of aptamers for X-spermatozoa by conducting real-time PCR assays targeting sex-specific genes. Aptamers X8, X19, X22 & X27 exhibited higher affinity for X-sorted sperm than Y in bovine semen. Western blot analysis showed an interaction between the aptamer and sperm protein at 35 kDa. The results underwent further analysis using in-gel mass spectrometry (MS) that predicted SPACA1 protein as the potential/putative aptamer binding protein on the sperm surface. Competitive western blot further confirmed aptamers' differential specificity for X-sperm.
conclusionsThe current work helps in creating new knowledge for the separation of Y-chromosome-bearing sperm from XY sperm populations that have the potential to produce good-quality cattle (cows). The work also generates proof of concept (POC) of using aptamers, which is cost-effective and could be used in sorting sex-specific spermatozoa without causing any ill effect on sperm.
