Abstract:
The progress made in understanding the molecular basis of mammalian cell transformation has led to the unifying concept of growth regulation and its disorders in cancer cells. Today it is well recognized that many products of "cancer genes" encode for proteins that regulate normal mitogenesis and apoptosis. Taken together, this indicates that the carcinogenic process may be viewed as a progressive disorder of signal transduction (1-6). In fact, many of the genes that are mutated or lost in cancer cells, including both the oncogenes and tumor suppressors, encode proteins that are crucial regulators for intra- as well as intercellular signal transduction (1-6). This conceptual framework has provided a basis for the development of novel anticancer strategies and therapeutic modalities with the aim to inhibit cancer growth either by blocking mitogenic signal transduction or to specifically induce apoptosis of cancer cells. Although these various approaches have not been validated clinically, these strategies are likely to identify compounds with less side effects compared to standard chemotherapeutic agents.
Insights
Cancer cell growth is a disorder of signal transduction, involving key proteins regulating cell division and death. New strategies target these pathways for less toxic cancer therapies.
Area of Science:
- Molecular Biology
- Oncology
- Cancer Research
Background:
- Mammalian cell transformation research reveals cancer involves disrupted growth regulation.
- Cancer genes encode proteins critical for cell division (mitogenesis) and programmed cell death (apoptosis).
- Carcinogenesis is increasingly understood as a progressive disorder of cellular signal transduction pathways.
Purpose of the Study:
- To present the unifying concept of growth regulation and its disorders in cancer cells.
- To highlight the role of cancer gene products in regulating normal cell proliferation and apoptosis.
- To establish a framework for developing novel anticancer strategies targeting signal transduction.
Main Methods:
- Review of molecular basis of mammalian cell transformation.
- Analysis of the role of oncogenes and tumor suppressors in signal transduction.
- Conceptualization of cancer as a signal transduction disorder.
Main Results:
- Cancer gene products are key regulators of intra- and intercellular signal transduction.
- Mutated or lost genes in cancer cells impact critical signaling pathways.
- Disordered signal transduction is central to cancer development and progression.
Conclusions:
- Cancer can be viewed as a progressive disorder of signal transduction.
- Novel therapeutic strategies aim to inhibit cancer growth by blocking mitogenic signals or inducing apoptosis.
- Targeting signal transduction pathways offers potential for anticancer agents with fewer side effects than traditional chemotherapy.
