Background/Objectives:
In the fight against ovarian cancer, various therapies have been employed, with a strong focus on developing novel derivatives of existing substances.
Methods:
In this study, we continue our research on novel xanthone derivatives in combination with mild hyperthermia, targeting ovarian cancer cell lines TOV-21G and SK-OV-3. Using qPCR arrays, we analyzed 84 cellular stress-related genes categorized into anti-oxidant and pro-oxidant enzymes, molecular chaperones, and xenobiotic metabolism including the cytochrome P450 group. Furthermore, we conducted in silico analyses to investigate the pathways of the most affected genes, gene set enrichment, and gene ontology.
Results:
The most significant changes were observed in SOD2, SOD3, CYP2F1, CYP1B1, and HMOX1. Additional changes related to drug toxicity and the postulated mechanism of action were also identified. Based on in silico analyses, we concluded that the primary node of hyperthermia-induced changes is HSPA1A. Heat-induced alterations predominantly revolve around misfolded proteins, monooxygenase activity, and ATPase activity.
Conclusions:
To summarize, the combined therapy of novel xanthone derivatives and mild hyperthermia shows promising results and warrants further investigation to fully elucidate the mechanisms of action underlying these effects.
Insights
Novel xanthone derivatives combined with mild hyperthermia show promise against ovarian cancer. This therapy impacts cellular stress genes, including antioxidant enzymes and cytochrome P450, suggesting a potential new treatment strategy.
Area of Science:
- Oncology
- Pharmacology
- Biochemistry
Background:
- Ovarian cancer treatment focuses on novel therapeutic agents.
- Xanthone derivatives are being explored for their anti-cancer potential.
Purpose of the Study:
- To investigate the efficacy of novel xanthone derivatives combined with mild hyperthermia against ovarian cancer.
- To analyze the impact of this combined therapy on cellular stress-related genes.
Main Methods:
- Utilized qPCR arrays to assess 84 cellular stress genes in ovarian cancer cell lines (TOV-21G, SK-OV-3).
- Analyzed genes involved in antioxidant/pro-oxidant activity, molecular chaperones, and xenobiotic metabolism (cytochrome P450).
- Performed in silico analyses for pathway investigation, gene set enrichment, and gene ontology.
Main Results:
- Significant alterations observed in SOD2, SOD3, CYP2F1, CYP1B1, and HMOX1 gene expression.
- Identified HSPA1A as a primary node for hyperthermia-induced changes.
- Heat-induced alterations linked to misfolded proteins, monooxygenase activity, and ATPase activity.
Conclusions:
- Combined therapy of xanthone derivatives and mild hyperthermia demonstrates therapeutic promise for ovarian cancer.
- Further research is needed to fully understand the underlying mechanisms of action.
- This approach may offer a novel strategy for ovarian cancer treatment.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
