Antiangiogenic Activity of n-hexane Insoluble Fraction and Its Tylophorine Component from Ficus septica Leaves in Chicken Chorioallantoic Membrane Induced by bFGF.
Article in Asian Pacific journal of cancer prevention : APJCP, 2023. 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
objectiveFicus septica is an Indonesian medicinal plant traditionally used to treat various illness, including cancer. The n-hexane insoluble fraction of the ethanolic extract of F. septica leaves (HIFFS) shows a potential anticancer activity against breast cancer cell line T47D. Considering that angiogenesis is a pivotal factor in malignant cancer growth, progression, and invasion, we aimed to investigate the antiangiogenic effect of HIFFS on chicken chorioallantoic membrane (CAM) induced by bFGF. We also evaluated tylophorine, the cytotoxic alkaloid of F. septica.
methodsChicken CAM was used to assess the antiangiogenic effect. Fertilized chicken eggs were induced with basic fibroblast growth factor (bFGF) ex ovo. Prior to bFGF induction, HIFFS (2.33, 4.65, 6.98, and 9.30 μg/mL) or tylophorine (9.20 µM) was added (10 µL) to a paper disk and implanted to the CAM. After 48 h of incubation, each treatment group was photographed, and the number of new blood vessel was calculated and compared with that in the solvent-treated group to determine the antiangiogenic activity. Histology of the CAM was evaluated after hematoxylin-eosin and Mallory acid fuchsin staining.
resultsWe found that HIFFS at low concentrations (2.33, 4.65, 6.98, and 9.30 μg/mL) inhibited angiogenesis activity (31.87, 41.99, 53.65, and 70.08, respectively) in chicken CAM induced by bFGF. Tylophorine (9.20 µM) also showed similar antiangiogenesis activity in the same model. Histopathology analysis revealed that HIFFS and tylophorine reduced the number of new blood vessels in CAM induced by bFGF.
conclusionHIFFS and tylophorine showed antiangiogenic effect on chicken CAM induced by bFGF. This finding emphasized the potential of F. septica as a candidate anticancer agent.
