Induction of Smooth Muscle Differentiation in Fibroblasts by Modulation of Cytoplasmic Actin Ratio.
Article in International journal of molecular sciences, 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
Myogenic differentiation is a powerful mechanism for generating diverse cell types from fibroblasts. Here, we show that targeted suppression of β-actin by RNA interference in human fibroblasts triggers coordinated molecular and structural changes consistent with trans-differentiation toward SMC-like phenotype. This conversion is marked by upregulation of smooth muscle differentiation markers (α- and γ-smooth muscle actins, SM22, smooth muscle myosin, desmin, vinculin) at mRNA and protein levels, together with distinct morphological alterations: increased cell area, loss of polarity, and reorganization of the actin cytoskeleton. Notably, β-actin-downregulated fibroblasts exhibited a focal adhesion architecture that differed from parental fibroblasts. These findings indicate that β-actin downregulation may provide a novel
