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

Hypoxia-induced Pyrroline-5-Carboxylate Reductase 1 (PYCR1) is implicated in bladder cancer (BC), but its specific role remains elusive. This study investigated how PYCR1 promotes BC progression through glycolysis, histone H3 Lysine 18 Lactylation (H3K18la), and Solute Carrier Family 6 Member 14 (SLC6A14)-driven glutamine catabolism. Here, BC cell lines were cultured under hypoxia to evaluate changes in PYCR1 expression, glycolysis, and lactate production. The xenograft and metastasis models in nude mice were used to validate the role of the PYCR1/H3K18la/SLC6A14 axis in BC progression. GEPIA Bioinformatics database data showed that PYCR1 was upregulated in BC and was associated with poor prognosis. The PYCR1 positive expression rate in BC tissues was increased. Hypoxia induced PYCR1 expression in BC cells, enhancing glycolysis and lactate production, which increased H3K18la levels. Upregulated SLC6A14 expression promoted glutamine catabolism and enhanced BC cell proliferation, migration, and invasion. PYCR1 knockdown inhibited H3K18la levels, SLC6A14 expression, and BC cell aggressiveness; SLC6A14 overexpression reversed these effects.
