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

Sex determination and differentiation in ectotherms are very complicated affairs and usually affected by both genetic and environmental factors. Because of their temperature-sensitive expression, heat shock proteins (HSPs) are good candidates for temperature-dependent sex determination (TSD). Similar to most thermosensitive fish species, the male to female ratio increases with temperature in yellow catfish (Pelteobagrus fulvidraco). Yellow catfish is also a type of sexual size dimorphic fish, and the male individuals grow much faster than females of the same age. Therefore, research of sex differentiation in yellow catfish is important in aquiculture. In this attempt, a total of seven HSPs and related genes were identified from transcriptomes of yellow catfish by 454 pyrosequencing and Solexa sequencing that we did previously, including five genes with complete open reading frame (ORF). Phylogenetically, all these genes were compared with their counterparts from other vertebrates. All these genes were sex-biased expressed in gonads. Hspa5, Hip, and Cdc37 were expressed more highly in ovary than in testis, whereas Hsp90α, Hspb2, Hspb8, and Hspbp1 were expressed more highly in testis than in ovary. Additionally, the expression of these genes was assessed after 17α-methyltestosterone (MT) and 17α-ethinylestradiol (EE2) treatment, respectively. Our result showed that working as co-chaperones, these HSPs and related genes may regulate sex steroid receptor activities to influence gonad development in yellow catfish. Our work would help in the understanding of the mechanism of sexual differentiation in teleosts.
