Identification of mitogen-activated protein kinase phosphatase-1 (MKP-1) protein partners using tandem affinity purification and mass spectrometry.
Article in Pharmacological reports : PR, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAccording to the World Health Organization Report, depressive disorders affect about 10% of the population. The molecular mechanism of the pathogenesis of depression is still not well understood. The new findings point to phosphatases as potential targets for effective depression therapy. The aim of the present work was the development of a method that would enable the identification of mitogen-activated protein kinase phosphatase-1 (MKP-1) protein partners using a proteomic approach.
methodsThe research was carried out using the PC12 cell line, often used as a model for neurobiological research. The use of the procedure for efficient purification of protein complexes-tandem affinity purification (TAP) will facilitate the identification of proteins interacting with MKP-1, a potential goal of effective antidepressant therapy.
resultsIdentified proteins belong to various groups: cytoskeletal, ribosomal, nucleic acid binding, chaperones, and enzymes and may potentially be involved in the molecular mechanism of depression.
conclusionsThe presented protocol for the purification of protein complexes is universal and can be successfully used in different mammalian cell lines. Proteins identified in the present work have been reported in the literature concerning studies on depressive disorders, which speaks in favour of their role in depression.
