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

Retinoic acid receptor α (RARA), a retinoic acid-dependent transcription factor, is expressed in both somatic and germ cells of the testis. Rara-null male mice with global Rara mutations displayed severely degenerated testis and infertility phenotypes. To elucidate the specific responsibility of germ cell RARA in spermatogenesis, Rara was deleted in germ cells, generating germ cell-specific Rara conditional knockout (cKO) mice. These Rara cKO animals exhibited phenotypes of quantitatively reduced epididymal sperm counts and disorganized germ cell layers in the seminiferous tubules, which worsened with aging. Abnormal tubules lacked lumen, contained vacuoles, and showed massive germ cell sloughing, all characteristics similar to those observed in Rara-null tubules. Spermatocyte chromosomal spreads revealed a novel role for germ cell RARA in modulating the integrity of synaptonemal complexes and meiotic progression. Furthermore, the initiation of spermatogenesis from spermatogonial stem cells was decreased in Rara cKO testes following busulfan treatment, supporting a role of germ cell RARA in spermatogonial proliferation. Collectively, the evidence in this study indicates that RARA produced in male germ cells has a broad spectrum of functions throughout spermatogenesis, which includes the maintenance of seminiferous epithelium organization, the integrity of the meiotic genome, and spermatogonial proliferation and differentiation. The results further suggest that germ cell RARA has dual functions: intrinsically in germ cells, balancing proliferation and differentiation of spermatogonia, and controlling genome integrity during meiosis; and extrinsically in the crosstalks with Sertoli cells, controlling the cell junctional physiology for coordinating proper spatial and temporal development of germ cells during spermatogenesis.
