Evaluation of In Vitro Anticancer Activity and Apoptotic Potential of Wrightia Tinctoria Bark Extracts on Oral Cancer Cell Lines.
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. 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
BACKGROUND AND
objectivesBioprospecting of indigenous plants for biological/cytotoxic properties has become an area of growing interest in cancer research. Wrightia tinctoria is a lesser-studied plant widely distributed in India which is commonly used in traditional medicinal systems like Ayurveda and Siddha and holds potential as a source for novel therapeutic agents. In this study, the cytotoxic effects of Wrightia tinctoria bark extracts on oral cancer (KB) cell lines were evaluated, focusing on three different extraction solvents ethanol, ethyl acetate, and water. The present study aimed to evaluate and compare the cytotoxic effects of Wrightia tinctoria bark extracts, while also investigating their potential to induce apoptosis which can contribute into exploration of new plant based anticancer agents.
methodsCytotoxic effects of ethanol, ethyl acetate, and aqueous extracts of Wrightia tinctoria bark were evaluated on human oral cancer cells (KB cell line). Cell viability was assessed by 3-(4,5-dimethylthiazoline- 2-yl)-2,5-diphenyltetrazolium bromide (MTT assay). Apoptosis was evaluated by acridine orange (AO) and ethidium bromide (EB) double staining method and expression of apoptotic enzymes Caspase 3 and Caspase 7 were measured by quantitative indirect ELISA technique.
resultsEthanol extract of Wrightia tinctoria bark exhibited highest cytotoxic activity towards oral cancer cell lines. The half-maximum inhibitory concentration (IC50) values of the ethanol, ethyl acetate, aqueous extracts were 75.084µg/ml, 179.743µg/ml and 115.258 µg/ml respectively. IC 50 concentration of ethanol and ethyl acetate extracts stimulated significant apoptosis in KB cells. Indirect ELISA showed increased expression of caspase 3 and caspase 7 among the cells on treatment with ethanol and ethyl acetate extracts.
conclusionEthanol extract of Wrightia tinctoria bark exhibited highest cytotoxic activity towards oral cancer cell lines and induced apoptotic changes. Further research may help us to identify newer, better anti cancer agents against oral cancer from Wrightia tinctoria bark.
