While cytotoxic and apoptotic properties have already been reported for some species of the genus there is not any report on cytotoxic effects of A. ciniformis. Petroleum ether (40-60), dichloromethane, ethyl acetate, ethanol and ethanol-water (50:50) extracts of the aerial parts of A. cinformis were subjected to cytotoxic and apoptotic evaluations on two cancer human cell lines (K562 and HL-60) and on J774 normal cells.Among multiple extracts evaluated for cytotoxicity, dichloromethane (CH2Cl2) and petroleum ether (PE) extracts were shown to possess the highest anti-proliferative effects on HL-60 and K562 cells with IC50 values of 31.3 and 25.5 μg/ml respectively. Apoptosis induction verified by sub-G1 peaks was seen in flow cytometry histograms. Increase in the amount of Bax protein, formation of DNA fragments, and cleavage of PARP to 24 and 89kDa sub units all confirmed induction of apoptosis by A. cinformis extracts. Taken together according to the result of the present study some extracts of A. cinformis could be considered as sources for natural cytotoxic compounds and further mechanistic and phytochemical studies are recommended to fully understand the underlying mechanisms of cnacer cell death as well as identification of responsible phytochemicals.}, keywords = {Artemisia ciniformis,asteraceae leukemic cell lines,petroleum ether extract,dichloromethane extract}, url = {https://journal.waocp.org/article_29721.html}, eprint = {https://journal.waocp.org/article_29721_70da7d2c6ff126c93e89418ed07cd4bc.pdf} }
