1 · What the graph read from it

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.

2 · The registry

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

Serine/threonine kinases of the TSSK (Testis-Specific Serine/Threonine Kinase) family play crucial roles in spermatogenesis and male fertility across species, but the underlying regulatory mechanism remains incompletely understood. In this study, we identified and characterized a novel TSSK homolog in Drosophila, named dTSSK2 (CG9222), which functions as the ortholog of human TSSK4. dTSSK2 is specifically expressed in the testis and localizes to individualization complexes during spermiogenesis. Disruption of dTSSK2 severely compromises sperm motility, leading to failed sperm transit into the seminal vesicle and male infertility. Phosphoproteomic analyses reveal that dTSSK2 coordinates sperm flagella assembly and motility by phosphorylating proteins involved in microtubule organization, organelle assembly, and flagella structure. Notably, dTSSK2 phosphorylates the substrate Gudu at Ser9, which partially contributes to individualization complex integrity and sperm motility. These findings elucidate the critical role of dTSSK2-mediated phosphorylation in regulating Drosophila male fertility.
