Abstract:
DNA damage response and repair (DDR) is a tightly controlled process that serves as a barrier to tumorigenesis. Consequently, DDR is frequently altered in human malignancy, and can be exploited for therapeutic gain either through molecularly targeted therapies or as a consequence of therapeutic agents that induce genotoxic stress. In select tumor types, steroid hormones and cognate receptors serve as major drivers of tumor development/progression, and as such are frequently targets of therapeutic intervention. Recent evidence suggests that the existence of crosstalk mechanisms linking the DDR machinery and hormone signaling pathways cooperate to influence both cancer progression and therapeutic response. These underlying mechanisms and their implications for cancer management will be discussed.
Insights
The DNA damage response (DDR) pathway is crucial in preventing cancer. Its interaction with hormone signaling impacts tumor growth and treatment effectiveness, offering new therapeutic strategies.
Area of Science:
- Molecular Oncology

- Cancer Therapeutics
Background:
- The DNA damage response and repair (DDR) is a critical safeguard against cancer development.
- Alterations in DDR pathways are common in human cancers and represent therapeutic targets.
- Steroid hormones and their receptors are key drivers in certain cancers, making them targets for treatment.
Purpose of the Study:
- To explore the crosstalk mechanisms between DDR and hormone signaling pathways.
- To understand how these interactions influence cancer progression.
- To discuss the implications for cancer management and therapeutic strategies.
Main Methods:
- Review of recent scientific literature.
- Analysis of molecular mechanisms linking DDR and hormone signaling.
- Discussion of clinical implications.
Main Results:
