چکیده
Aim: The present study was conducted to survey the potential cytotoxic influence of freeze-dried aqueous extract of its fruits on gastrointestinal cell lines, namely AGS (human gastric carcinoma) and KYSE30 (human esophageal squamous cell carcinoma. Background: Rosemary (Rosmarinus officinalis) is a wild medicinal plant shown to have anticancer activity. Carnosic and rosmarinic acids are compounds, obtained from it through several extraction methods. Methods: The aqueous extract of the fruits of R.officinalis was freeze-dried, and KYSE30 and AGS cancer cell lines were treated with crude extract. Cytotoxic effect of the extracts on the cell lines was examined using 3-(4, 5-Dimethylthiazol-2-yl)-2, 5diphenyltetrazolium bromide (MTT) and neutral red assay. Apoptotic cells were detected with ethidium bromide/acridine orange (EB/AO). Cell-cycle distributions were evaluated by flow cytometry. Results: IC50 values were 4.1, 1.8 and 1.3 mg/mL for AGS cell lines after 24, 48 and 72 hours by MTT assay, respectively, and 4.4,2.1 and 1.1 mg/mL by neutral red assay, respectively. IC50 values for KYSE30 cell lines were 600, 180 and 150 mg/mL after 24, 48 and 72 hoursby MTT assay, and 860, 270 and 230 mg/mL by neutral red. EB/AO staining increased in apoptotic cells. After 24 hof treatment at different concentrations, significant increases and decreases in population were shown at G2/M and G1 phases, respectively. Conclusion: The aqueous extract of the fruits of R.officinalis was freeze-dried, and KYSE30 and AGS cancer cell lines were treated with crude extract. Cytotoxic effect of the extracts on the cell lines was examined using 3-(4, 5-Dimethylthiazol-2-yl)-2, 5diphenyltetrazolium bromide (MTT) and neutral red assay. Apoptotic cells were detected with ethidium bromide/acridine orange (EB/AO). Cell-cycle distributions were evaluated by flow cytometry. é 2017 RIGLD.
