Effects Atra on MMP-9 Activity and Integrin Expression in Choriocarcinoma Culture Cell Line Bewo (ATCC CCL-98).
Article in Asian Pacific journal of cancer prevention : APJCP, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveChoriocarcinoma is characterized by aggressive growth and metastasis, and integrins and matrix metalloproteinase-9 (MMP-9) play crucial roles in its progression. ATRA (All-trans retinoic acid) has been shown to have anti-tumor effects in various cancers, poses a 15-20% malignancy risk. This study investigates the effects ATRA on MMP-9 activity and integrin expression in the choriocarcinoma cell line BeWo, and to explore the potential mechanisms underlying these effects.
methodsThis is an experimental study using choriocarcinoma cell line BeWo. Six treatment groups were established to varying concentrations of ATR and one group served as a control without ATRA exposure. The groups were labelled with fluorescence and performed with flowcytometry to determine MMP-9 and integrin expression. Data was presented as mean ± SD and analyzed using one-way ANOVA with post-hoc tests in which p-value <0.05.
resultATRA at the doses of 100, 200, 400, and 800 μg/ml significantly decreased the MMP-9 activity compared to those in the control group. Furter, ATRA at the doses of 100, 200, 400, and 800 μg/ml significantly increased the integrin expression compared to those in the control group.
conclusionATRA might decrease the MMP-9 activity as an invasive factor and increase integrin expression as an adhesive factor in the BeWo choriocarcinoma cell line that might play a role in the metastasis mechanism.
