Commercially available PGC-1α antibodies vary greatly in specificity and sensitivity.
Article in microPublication biology, 2024. 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
Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) is an inducible transcriptional coactivator protein involved in mitochondrial biogenesis and metabolism. PGC-1α exhibits a short half-life and low abundance, rendering its detection challenging by immunoblotting. This study compared the specificity and sensitivity of seven commercially available PGC-1α antibodies towards the full-length mouse PGC-1α1 isoform, using overexpression and knockdown in primary mouse hepatocytes. While all antibodies identified overexpressed PGC-1α1, only one detected endogenous PGC-1α1. This study demonstrates wide variability in sensitivity and specificity of PGC-1α antibodies and suggests that controls should be used to differentiate PGC-1α protein from non-specific bands.
