Exposure to amitraz, fipronil and permethrin affects cell viability and ABC transporter gene expression in an Ixodes ricinus cell line

Background: Bromelain enhances anticancer impacts to chemotherapeutic agents. The question as to whether bromelain does promote in-vitro cytotoxic and proapoptotic effects of cisplatin on human prostatic carcinoma PC3 cell line was investigated. Materials and Methods: PC3 (human prostatic carcinoma) cells were treated either single or in combination with bromelain and/or cisplatin. MTT, clonogenic assay, flow cytometry and real-time quantitative polymerase chain reaction were used to investigate cell viability, colony formation, proapoptotic potential and p53 gene expression, respectively. Results: Cisplatin (IC10) combined with bromelain (IC40) significantly affected PC3 cell viability, inhibited colony formation, as well increased p53 proapoptotic gene expression compared to cisplatin single treatment. Nevertheless, bromelain-cisplatin chemoherbal combination did not display any additive proapoptotic effect compared to single treatments. Conclusion: Bromelain-cisplatin chemoherbal combination demonstrated synergistic in-vitro anticancer effect on human prostatic carcinoma cell line, PC3, that drastically reduced required cisplatin dose.

Background: To increase the therapeutic effect of drugs to combat diseases, combination therapy with current chemical drugs and new medicines derived from medicinal plants is necessary. Objectives: The present work aimed to investigate the effect of hydroalcoholic extract of two medicinal plants, Ephedra major and Momordi cacharantia (Carla), and resveratrol drug on cell viability and expression levels of caspase-3 gene in MCF-7 cell line. Methods: In this experimental study, the hydroalcoholic extraction of tested plants was done with a Soxhlet extractor. The MTT assay and real-time PCR were used to determine cell toxicity and caspase-3 gene expression levels, respectively. Results: The highest and lowest cytotoxic effects of plant extracts and resveratrol were observed at concentrations of 500 and 150 µg/mL, respectively. The highest level of the caspase-3 gene expression was observed after 72 h of incubation by different concentrations of plant extracts and resveratrol. Conclusions: It can be concluded that both plant extracts could influence cell viability in MCF-7 cells via the increase of cell toxicity and expression of caspase3 gene. Thus, these species could be used in the pharmaceutical industry.
