Distinct Mitochondrial Recovery Dynamics Following Taxol Removal in Triple-Negative Breast Cancer Cells.
Article in Cells, 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
Drug resistance in TNBC is associated with metabolic plasticity, yet little is known about how mitochondrial and cellular states evolve after chemotherapeutic withdrawal. We used optical redox imaging (ORI) microscopy and complementary functional measurements to characterize post-Taxol recovery in two TNBC cell lines with different Taxol sensitivities. Whole-dish nuclear counting following 48 h Taxol treatment confirmed that HCC1806 cells responded at lower Taxol concentrations than MDA-MB-436 cells. Recovery was subsequently monitored following extracellular Taxol withdrawal using mitochondrial redox indices, mitochondrial reactive oxygen species (mito-ROS), mitochondrial membrane potential (MMP), multinucleation, and live- and dead-cell counts. HCC1806 cells showed substantial recovery of several mitochondrial parameters and resolution of multinucleation by 96 h; however, a late reductive shift in the optical redox ratio (ORR), reduced MMP, and attenuated live-cell population expansion indicated incomplete redox and functional recovery. In contrast, MDA-MB-436 cells exhibited persistent elevations in Fp and ORR through 144 h, residual multinucleation, and little sustained live-cell population expansion. These findings demonstrate that mitochondrial, multinucleation, and population-level recovery can proceed on different timescales and that post-treatment recovery differs markedly between TNBC models with different Taxol sensitivities. Longitudinal ORI provides a non-destructive approach for characterizing persistent post-treatment metabolic states and, together with functional measurements, may facilitate investigation of recovery-associated phenotypes relevant to therapeutic response.
