Regulation of organic anion transporting polypeptide 1B1 transport function by concurrent phosphorylation and lysine-acetylation: A novel posttranslational regulation mechanism.
Article in Molecular pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Organic anion transporting polypeptide (OATP) 1B1 is crucial for hepatic uptake of many drugs and endogenous substrates. The clinically relevant OATP1B1 c.521 T>C (V174A) polymorphism exhibits reduced transport activity in vitro and in vivo in humans. Previously, we reported increased total phosphorylation of V174A-OATP1B1 compared to wild-type (WT)-OATP1B1, although the differentially phosphorylated sites remain to be identified. Lysine-acetylation, a key posttranslational modification (PTM), has not been investigated in OATP1B1. This study aimed to identify differential PTMs of WT-OATP1B1 and V174A-OATP1B1 by quantitatively comparing the relative abundance of modified peptides using liquid chromatography-tandem mass spectrometry-based proteomics and to assess the impact of these PTMs on OATP1B1 transport function using [
