Abstract:
Maintaining a tumour cell's resistance to apoptosis (organized cell death) is essential for cancer to metastasize. Signal molecules play a critical function in the tightly regulated apoptotic process. Apoptosis may be triggered by a wide variety of cellular stresses, including DNA damage, but its ultimate goal is always the same: the removal of damaged cells that might otherwise develop into tumours. Many chemotherapy drugs rely on cancer cells being able to undergo apoptosis as a means of killing them. The mechanisms by which DNA-damaging agents trigger apoptosis, the interplay between pro- and apoptosis-inducing signals, and the potential for alteration of these pathways in cancer are the primary topics of this review.
Insights
Cancer cells evade apoptosis to metastasize. This review explores how DNA damage triggers apoptosis, crucial for chemotherapy and tumor removal.
Area of Science:
- Molecular Biology
- Cell Biology
- Oncology
Background:
- Tumorigenesis and metastasis rely on cancer cells resisting apoptosis (programmed cell death).
- Signal molecules are critical regulators of the highly controlled apoptotic process.
- Apoptosis removes damaged cells, preventing tumor development.
Conclusions:
- Understanding apoptosis mechanisms is vital for cancer therapy development.
- Targeting apoptotic pathways holds promise for overcoming cancer drug resistance.
- Further research into the interplay of signaling molecules can reveal new therapeutic strategies.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
