Background/Aim:
Cervical cancer remains a significant global challenge, necessitating novel therapeutic strategies beyond conventional radiotherapy and chemotherapy. The anticancer potential of natural compounds has recently garnered increased recognition. This study aimed to expand this knowledge by exploring the molecular mechanisms by which spinach extract (SE) influences the growth and survival of HeLa cervical cancer cells.
Materials And Methods:
HeLa cells were exposed to SE or medium alone. A clonogenic survival assay was performed following SE exposure, followed by a quick cell proliferation assay. RT-PCR was used to assess the expression of key proliferative and anti-proliferative molecules, and IHC was used to elucidate protein expression. TUNEL staining and caspase-3 assays measured apoptosis in the HeLa cells.
Results:
SE resulted in increased apoptosis and decreased proliferation of HeLa cells. SE reduced the expression of pro-proliferative molecules, including cyclin B and cyclin D, in HeLa cells. It also reduced the expression of the anti-apoptotic molecule FLIP. Unexpectedly, the expression of p18 was decreased.
Conclusion:
SE is a low-cost nutritional supplement that was able to significantly slow the growth and promote apoptosis of HeLa cervical cancer cells by decreasing proliferative and anti-apoptotic molecules.
Insights
Spinach extract (SE) significantly slows cervical cancer cell growth and promotes apoptosis. This natural compound reduces key molecules that drive proliferation and inhibit cell death in HeLa cells.
Area of Science:
- Oncology
- Natural Compounds Research
- Molecular Biology
Background:
- Cervical cancer presents a significant global health challenge, driving the search for novel therapeutic agents.
- Natural compounds are increasingly recognized for their potential anticancer properties.
- Conventional treatments like radiotherapy and chemotherapy have limitations, necessitating alternative strategies.
Purpose of the Study:
- To investigate the molecular mechanisms underlying the effects of spinach extract (SE) on HeLa cervical cancer cell growth and survival.
- To explore SE as a potential therapeutic strategy for cervical cancer.
Main Methods:
- HeLa cells were treated with spinach extract (SE).
- Assays included clonogenic survival, cell proliferation, RT-PCR for gene expression, immunohistochemistry (IHC) for protein expression, TUNEL staining, and caspase-3 activity assays.
- Key molecules related to proliferation and apoptosis were analyzed.
Main Results:
- Spinach extract (SE) significantly decreased HeLa cell proliferation and increased apoptosis.
- SE reduced the expression of pro-proliferative molecules (cyclin B, cyclin D) and the anti-apoptotic molecule FLIP.
- A decrease in p18 expression was observed, which warrants further investigation.
Conclusions:
- Spinach extract (SE), a cost-effective nutritional supplement, demonstrates significant anticancer effects against HeLa cervical cancer cells.
- SE effectively inhibits cancer cell growth and induces apoptosis by modulating key molecular pathways.
- These findings support the exploration of SE as a complementary therapeutic approach for cervical cancer.
