Abstract:
During evolution, connections between the major signalling pathways were established to provide cells with an ability to deal with perturbations of homeostasis. However, these feedback and crosstalk mechanisms can become a liability in the treatment of cancer, as the inhibition of one cancer-relevant signalling pathway can lead to the activation of a secondary survival pathway that interferes with cancer drug efficacy. In this review, we discuss connections between signalling pathways in relation to cancer therapy and we evaluate the use of genetic approaches to identify pathway crosstalk. We also discuss how insight into connections between signalling pathways can be exploited to design powerful synthetic lethal drug combination therapies for the treatment of cancer.
Insights
Cancer cells exploit interconnected signaling pathways for survival. Understanding these connections, particularly pathway crosstalk, is crucial for developing effective combination cancer therapies and overcoming drug resistance.
Area of Science:
- Molecular Biology
- Cancer Biology
- Pharmacology
Background:
- Cellular homeostasis is maintained by interconnected signaling pathways.
- Pathway crosstalk and feedback mechanisms, while adaptive, can hinder cancer treatment.
- Inhibiting one cancer pathway may activate compensatory survival pathways, reducing drug efficacy.
Purpose of the Study:
- To review signaling pathway connections in cancer therapy.
- To evaluate genetic approaches for identifying pathway crosstalk.
- To explore exploiting pathway insights for synthetic lethal drug combinations.
Main Methods:
- Literature review of signaling pathway interactions in cancer.
