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

backgroundProlactin (PRL) is a key reproductive hormone that regulates follicular development through endocrine and paracrine mechanisms. However, its specific role in porcine follicular development remains unclear.

methodsIn the in vivo experiments, follicular fluid and tissue cells were obtained from small (1-2 mm), medium (3-4 mm), and large (5-6 mm) porcine follicles. PRL levels in follicular fluid were measured by ELISA. The expression levels of genes and proteins related to follicular development were assessed using quantitative real-time PCR (RT-qPCR) and Western blotting (WB). In the in vitro experiments, CCK-8, RT-qPCR, and WB were used to detect the effects of different concentrations (0, 30, and 300 ng/mL) of recombinant porcine prolactin (prPRL) on granulosa cell (GC) proliferation, steroid hormone synthesis, and angiogenesis, and transcriptome sequencing was performed.

resultsThe PRL concentration was significantly higher in large follicles compared to small and medium follicles. During follicular development, expression levels of PRL, PRL receptor (PRLR), proteolytic enzymes (CTSD, MMP2, MMP14, and BMP-1), and angiogenic factors (VEGFA and FGF-2) increased and then decreased. Moreover, prPRL promoted GC proliferation, increased the expression of PCNA and cyclin D1, upregulated steroidogenesis-related genes

conclusionsPRL may regulate porcine follicle development by affecting cell proliferation and angiogenesis in GCs through the Hippo, JAK/STAT and Rap1 signaling pathways.
