Probing transcription factor subsets in gene regulatory networks.
Article in Algorithms for molecular biology : AMB, 2026. 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
Transcription factors (TFs) are essential players in the regulation of gene expression and thus have been the subject of interest in the context of diseases and the manipulation of specific cell functions or pathways. The complex interplay of TFs and genes can be modeled as a network, in which each edge represents a regulatory influence. A challenge in such networks is the identification of a set of TFs with the maximum regulatory influence, which is of particular importance in the context of perturbation studies. We model the task of finding a set of TFs to maximize the influence on a set of genes as a probing problem in a bipartite graph. We test different adaptive and non-adaptive algorithms on simulated graphs and discuss their properties and adaptivity gap. Then, we apply the algorithms on real-life data to find TFs regulating genes involved in T-cell mediated immunity and lymphoid leukemia. The approach has minimal data requirements and can be readily applied to all other types of bipartite networks.
