3,5,3'-Triiodo-L-Thyronine Regulates Actin Cytoskeleton Dynamic in The Differentiated PC-12 Cells during Hypoxia through An αvβ3 Integrin.
Article in Cell journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveThyroid hormones are involved in the pathogenesis of various neurological disorders. Ischemia/hypoxia that induces rigidity of the actin filaments, which initiates neurodegeneration and reduces synaptic plasticity. We hypothesized that thyroid hormones via alpha-v-beta-3 (αvβ3) integrin could regulate the actin filament rearrangement during hypoxia and increase neuronal cell viability. MATERIALS AND
methodsIn this experimental study, we analysed the dynamics of actin cytoskeleton according to the G/F actin ratio, cofilin-1/p-cofilin-1 ratio, and p-Fyn/Fyn ratio in differentiated PC-12 cells with/without T3 hormone (3,5,3'-triiodo-L-thyronine) treatment and blocking αvβ3-integrin-antibody under hypoxic conditions using electrophoresis and western blotting methods. We assessed NADPH oxidase activity under the hypoxic condition by the luminometric method and Rac1 activity using the ELISA-based (G-LISA) activation assay kit.
resultsThe T3 hormone induces the αvβ3 integrin-dependent dephosphorylation of the Fyn kinase (P=0.0010), modulates the G/F actin ratio (P=0.0010) and activates the Rac1/NADPH oxidase/cofilin-1 (P=0.0069, P=0.0010, P=0.0045) pathway. T3 increases PC-12 cell viability (P=0.0050) during hypoxia via αvβ3 integrin-dependent downstream regulation systems.
conclusionThe T3 thyroid hormone may modulate the G/F actin ratio via the Rac1 GTPase/NADPH oxidase/ cofilin1signaling pathway and αvβ3-integrin-dependent suppression of Fyn kinase phosphorylation.
