- چکیده:
- چکیده انگلیسی: Objective: Eleutherine palmifolia (L.) Merr. extract (EPE) containing isoliquiritigenin and oxyresveratrol is believed to be an anticancer agent. This study evaluates colon histopathology, TNF-α, TGF-β, and hepatotoxicity on BALB/c mice colitis-associated colon cancer (CAC) model treated with EPE. Methods: In vivo study was performed on BALB/c mice CAC model induced by 10 mg/kgBW AOM on the first day followed by administration that each cycle consisted of 5% DSS in water for seven days and regular water for seven days. The indicators of the formation of CAC were observed by a fecal occult blood test (FOBT) and serum amyloid α (SAA) test. The treatment was conducted once a week started from the seventh week up to the twentieth week with six treatment groups: I was administrated by regular water only (negative control), II was administrated by AOM and DSS only (positive control), III was administrated by doxorubicin, IV-VI were treated by EPE (0.25 mg/kg BW, 0.50 mg/kg BW, and 1.00 mg/kg BW) respectively. The colon and liver’s histopathology was observed using hematoxylin-eosin (HE) staining, TNF-α with immunohistochemistry (IHC), and level measurement of TGF-β colon with ELISA reader. The data were used one-way ANOVA followed by post hoc as statistical analysis. Results: The administration of EPE increased the expression of TNF-α, the total of goblet cells of the colon, and decreased the level of TGF-β. Administration of EPE 0.50 mg/20g BW decreased a liver histopathological score but induced a histopathological alteration of the liver at a dose of 1.00 mg/20g BW. Conclusion: This study indicate that EPE could be recommended as a colon anticancer through increase the goblet cells, induce apoptosis through increase TNF-α, and decrease TGF-β.

- چکیده:
- چکیده انگلیسی: Objective: This study aims to isolate the active anticancer compound from ethyl acetate fraction extracted from
the roots of Calotropis gigantea and to determine the operating mechanism of the isolates towards WiDr colon cancer
cells. Methods: the isolation was conducted by using bioassay guided isolation approach method. The cytotoxic
potential was determined by using MTT method. The chemical structure was identified by using UPLCMS/MS and
NMR-1H spectroscopy. The cell cycle arrest and apoptosis induction were determined by flow cytometry method.
The expression of caspase-8 was determined by immunocytochemistry method. Results: The results showed that
the active compounds are obtained calotroposid A compound which is glycosides terpenoids. Calotroposide A
is capable of inhibiting the growth of WiDr colon cancer cells at IC50 17.23μg/ml. Cell apoptosis induction took place
and was indicated by cell apoptosis increase, S and G2/M accumulation and by caspase-8 expression. Conclusion:
Calotroposide A induces anticancer activity against WiDr colon cancer cells by means of apoptosis induction mechanism
through extrinsic pathway with increased expression of caspase-8.- انتشار مقاله: 28-02-1396
