Abstract:

Background and objectives: Ziziphora tenuior is considered as an appropriate protoscolicidal agent yet the mechanism of such effect is not known so far. The aim of this study was to evaluate the apoptotic effect of Z. tenuior extract on protoscolices of hydatid cyst. Methods: Protoscolices were collected aseptically and the Bradford test was employed to determine the number required for the experiments. Various concentrations of Z. tenuior extract (5, 50, and 100 mg/mL) was incubated with hydatid cyst protoscolices at 37 oC and 5% Co2 for 4 h. The apoptotic effect of Z. tenuior extract on hydatid cyst protoscolices and the evaluation of caspases 3, 8, and 9 activities were ditermined using ELISA-based commercial diagnostic kits. Results: In the present study, 50 and 100 mg/mL of Z. tenuior extract produced apoptosis in the protoscolices of hydatid cyst significantly (p<0.05). Also, the activity of caspase 3 at 50 and 100 mg/mL significantly increased by 29.99% and 36.01%, respectively (p<0.05). Similarly, caspase 9 also demonstrated a significant increased activity up to 15.23%, and 45.31% at the same concentrations used for caspase 3, respectively (p<0.05). Conclusion: Our findings in this study indicated that, Z. tenuior extract can induce apoptotic cell death on hydatid cyst protoscolices by increasing the activity of caspases 3 and 9 via the internal apoptotic pathway.

Rhein induces apoptosis of human gastric cancer SGC-7901 cells via an intrinsic mitochondrial pathway

Rhein is a primary anthraquinone found in the roots of a traditional Chinese herb, rhubarb, and has been shown to have some anticancer effects. The aim of the present study was to investigate the effect of rhein on the apoptosis of the human gastric cancer line SGC-7901 and to identify the mechanism involved. SGC-7901 cells were cultured and treated with rhein (0, 50, 100, 150, and 200 µM) for ...

Cisplatin-induced apoptosis in p53-deficient renal cells via the intrinsic mitochondrial pathway.

Nephrotoxicity is the major limiting factor for the use of cisplatin in cancer therapy. Recent studies have demonstrated an important role for p53 in cisplatin-induced renal injury. Nevertheless, pharmacological and genetic blockade of p53 only provides partial renoprotective effects, suggesting the presence of p53-independent injury mechanisms. To understand the p53-independent mechanisms, we ...
