Interconnection between DNA damage, senescence, inflammation, and cancer

Area of Science:

• Cellular Biology
• Cancer Research
• Immunology

Background:

• Cells possess intricate mechanisms like DNA damage response, senescence, cell death, and inflammation to counteract endogenous and exogenous threats.
• These cellular processes are increasingly recognized for their dual role in cancer: promoting its development and progression, while also offering avenues for prevention and treatment.

Purpose of the Study:

• To review the fundamental mechanisms of DNA damage induction, detection, and repair.
• To outline the processes of cell death, senescence, and inflammation, including their induction and abrogation.
• To explore the relationship between senescence, inflammation, and cancer, and their potential as therapeutic targets.

Main Methods:

• Literature review of cellular defense mechanisms.
• Analysis of DNA damage response pathways.
• Examination of senescence and inflammatory processes.
• Review of cancer biology literature connecting these pathways.

Main Results:

• Cellular defense mechanisms are crucial for maintaining genomic stability and organismal health.
• Interconnections exist between DNA damage response, senescence, cell death, and inflammation.
• These pathways are implicated in both cancer development and its potential therapeutic targeting.

Conclusions:

• Individual cellular pathways (DNA damage response, senescence, cell death, inflammation) are promising therapeutic targets in cancer.
• A multimodal therapeutic approach targeting the interconnections between these pathways may offer enhanced cancer treatment strategies.
• Understanding and manipulating senescence and inflammation holds significant potential for improving cancer therapies.
