Abstract:
The induction of apoptosis, a highly regulated and clearly defined mode of cell dying, is a vital tenet of modern cancer therapy. In this review we focus on three aspects of apoptosis research which we believe are the most crucial and most exciting areas currently investigated and that will need to be better understood in order to enhance the efficacy of therapeutic measures. First, we discuss which target to select for cancer therapy and argue that not the cancer cell as such, but its interaction with the microenvironment is a more promising and genetically stable site of attack. Second, the complexity of combination therapy is elucidated using the PI3-K-mediated signaling network as a specific example. Here we show that the current clinical approach to sensitize malignancies to apoptosis by maximal, prolonged inhibition of so-called survival pathways can actually be counter productive. Third, we propose that under certain conditions which will need to be clearly defined in future, chronification of a tumor might be preferable to the attempt at a cure. Finally, we discuss further problems with utilizing apoptosis induction in cancer therapy and propose a novel potential therapeutic approach that combines the previously discussed features.
Insights
Targeting cancer
Area of Science:
- Cancer Biology
- Cell Death Research
- Therapeutic Strategies
Background:
- Apoptosis, a regulated cell death, is central to cancer therapy.
- Enhancing apoptosis efficacy requires deeper understanding of key research areas.
- Current therapeutic strategies face challenges in clinical application.
Purpose of the Study:
- To review critical and emerging areas in apoptosis research for improved cancer therapy.
- To explore novel therapeutic targets beyond cancer cells themselves.
- To re-evaluate combination therapy approaches and tumor management strategies.
Main Methods:
- Review of current apoptosis research.
- Analysis of the tumor microenvironment as a therapeutic target.
- Examination of PI3-K signaling in combination therapy.
- Discussion of tumor chronification as a therapeutic option.
Main Results:
- The tumor microenvironment offers a more promising and stable therapeutic target than cancer cells alone.
- Prolonged inhibition of survival pathways in combination therapy can be counterproductive.
- Tumor chronification may be a viable strategy under specific conditions.
Conclusions:
- Novel therapeutic approaches should consider the tumor microenvironment and signaling network complexities.
- Revisiting combination therapy protocols and exploring tumor chronification are crucial for advancing cancer treatment.
- A novel therapeutic strategy integrating these features is proposed.

Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
