Purpose:
The limitations in cancer treatment and the inadequacy of classical methods have made it necessary to discover therapeutics in cancer treatment. The cytotoxicity of thymoquinone, which has quite different properties in terms of biological activities, in ovarian cancer cells, and the changes in the expression levels of apoptotic genes (p53/caspase-3 (casp-3)) were investigated.
Methods:
In the study, thymoquinone (5, 50, 100, 250 and 500 µM and 24, 48, 72 hours) were applied to ovarian adenocarcinoma cancer cell line (OVCAR3), at different concentrations. Cytotoxic effect of thymoquinone on OVCAR-3 cells were analyzed by MTT method, and apoptotic and pro-apoptotic gene expression levels (p53, Casp-3) of thymoquinone in cancer cells were analyzed by quantitative real-time polymerase chain reaction.
Results:
Thymoquinone, whose effect has been revealed in many types of cancer, was shown to significantly reduce the viability of OVCAR3 cancer cells depending on the dose and time (p < 0.05). It was also determined that Casp-3 and p53 gene expressions increased in OVCAR3 cells.
Conclusions:
Considering the in-vitro cytotoxic activity and apoptotic gene expressions of thymoquinone, an important treatment agent, since it is a promising agent for the future of cancer treatment, more comprehensive studies may pave the way for its clinical use.
Insights
Thymoquinone effectively reduced ovarian cancer cell viability and increased apoptotic gene expression (p53 and Caspase-3). This suggests thymoquinone is a promising therapeutic agent for ovarian cancer treatment.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Classical cancer treatments have limitations.
- Novel therapeutic agents are needed for effective cancer treatment.
- Thymoquinone exhibits diverse biological activities.
Purpose of the Study:
- To investigate the cytotoxic effects of thymoquinone on ovarian cancer cells.
- To analyze the impact of thymoquinone on apoptotic gene expression (p53 and Caspase-3) in ovarian cancer.
- To evaluate thymoquinone as a potential therapeutic agent for ovarian cancer.
Main Methods:
- Ovarian adenocarcinoma cells (OVCAR3) were treated with varying concentrations of thymoquinone over different time periods.
- Cell viability was assessed using the MTT assay.
- Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to analyze the expression levels of p53 and Caspase-3 genes.
Main Results:
- Thymoquinone demonstrated a significant dose- and time-dependent reduction in OVCAR3 cell viability (p < 0.05).
- The expression of both Caspase-3 and p53 genes was found to increase in OVCAR3 cells treated with thymoquinone.
- These findings indicate thymoquinone's cytotoxic and pro-apoptotic effects on ovarian cancer cells.
Conclusions:
- Thymoquinone exhibits significant in-vitro cytotoxic activity against ovarian cancer cells.
- The observed increase in apoptotic gene expression supports thymoquinone's role in inducing apoptosis.
- Thymoquinone is a promising agent for future ovarian cancer treatment, warranting further comprehensive studies for potential clinical application.
