Mitochondrial dysfunction and apoptosis-related gene activation induced by combined ethyl acetate fractions of Uncaria sp. and Selaginella doederleinii in Saccharomyces cerevisiae.
Article in Molecular biology reports, 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
backgroundThe combination of ethyl acetate fractions from Uncaria sp. and Selaginella doederleinii (EAF-BC) holds potential as an anticancer agent; however, its underlying molecular mechanism remains unclear. This study aimed to determine the anticancer potential of these combinations by evaluating the hallmarks of apoptosis using a Saccharomyces cerevisiae model. METHODS AND
resultsYeast cells were incubated with EAF-BC at concentrations of 5, 10, and 100 ppm for 24 h. The analyzed parameters included petite colony frequency, mitochondrial activity, cell surface morphology, phosphatidylserine externalization, DNA fragmentation, and apoptosis-related gene regulation (FSH3, AIF1, and YCA1). The results showed that EAF-BC induced mitochondria-driven apoptosis in a dose-dependent manner. The 100-ppm concentration caused severe mitochondrial damage, yielding 85% petite colony formation, reduced mitochondrial fluorescence, surface wrinkling, phosphatidylserine externalization, and DNA fragmentation. This concentration significantly upregulated FSH3 (6-fold), YCA1 (3-fold), and AIF1 (2-fold) expression. Lower concentrations (5 and 10 ppm) also induced apoptosis, although the activity was lower.
conclusionEAF-BC induced apoptosis-associated cellular changes accompanied by mitochondrial dysfunction in Saccharomyces cerevisiae, as evidenced by increased petite colony formation and multiple apoptotic hallmarks.
