Abstract:
Target-based therapy has been a promising anti-cancer strategy in the preclinical setting, but its efficacy is still limited in clinical practice. The latter was probably due to the lack of identification of molecular targets in order to predict clinical response and for the existence of multiple survival compensatory downstream pathways. Therefore, the use of downstream targets could be useful in order to avoid these overcoming pathways. One of these targets is Raf-kinase. In this review we describe the structure and functions of the components of Raf-kinase family and their relevance in proliferation and survival of tumor cells. Moreover, we illustrate the signal transduction pathways regulated by Raf-kinases. The main preclinical and clinical results obtained with the use of the Raf-kinase inhibitor BAY 43-9006 or sorafenib are also described. The multi-target function of sorafenib is also explained and the disclosure of new therapeutic opportunities based on the dual inhibition of cancer proliferation and neo-angiogenesis is discussed. In conclusion, Raf-kinase appears an appealing therapeutic target, even it other preclinical and clinical studies are warranted in order to evaluate the activity of sorafenib both in monotherapy and in combination with other agents.
Insights
Targeting Raf-kinase, a key pathway in tumor cell survival, offers promise for cancer therapy. Inhibitors like sorafenib show potential by blocking proliferation and neo-angiogenesis, warranting further clinical studies.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Target-based cancer therapies show promise but face limitations in clinical settings.
- Compensatory downstream pathways can hinder the efficacy of traditional anti-cancer strategies.
- Identifying molecular targets is crucial for predicting clinical response.
Purpose of the Study:
- To review the structure, function, and relevance of the Raf-kinase family in tumor cell proliferation and survival.
- To illustrate signal transduction pathways regulated by Raf-kinases.
- To discuss preclinical and clinical results of the Raf-kinase inhibitor sorafenib (BAY 43-9006).
Main Methods:
- Literature review of Raf-kinase family components and signaling pathways.
- Analysis of preclinical and clinical data for sorafenib (BAY 43-9006).
- Discussion of sorafenib's multi-target function and therapeutic potential.
Main Results:
- Raf-kinase family members play a significant role in tumor cell proliferation and survival.
- Sorafenib (BAY 43-9006) has demonstrated preclinical and clinical activity.
- Sorafenib exhibits multi-target functions, inhibiting both cancer proliferation and neo-angiogenesis.
Conclusions:
- Raf-kinase represents an attractive therapeutic target for anti-cancer strategies.
- Sorafenib's dual inhibition of proliferation and neo-angiogenesis offers new therapeutic opportunities.
- Further preclinical and clinical studies are needed to evaluate sorafenib's efficacy in monotherapy and combination treatments.
