Drug-tolerant persister cells in cancer: the cutting edges and future directions

Area of Science:

• Oncology
• Microbiology
• Pharmacology

Background:

• Drug-tolerant persister (DTP) cells were first identified in antibiotic-resistant bacterial biofilms.
• Similar DTP cell populations exhibiting treatment resistance, independent of genomic alterations, have been found in cancer.
• While DTP cells' biological roles in cancer are increasingly understood, their clinical impact on treatment resistance requires further investigation.

Purpose of the Study:

• To define the drug-tolerant persister (DTP) cell phenotype.
• To explore the characteristics, biomarkers, and vulnerabilities of DTP cells.
• To encourage research for improved anticancer therapies targeting DTP cells.

Main Methods:

• Literature review and synthesis of existing research on DTP cells in bacteria and cancer.
• Analysis of biological characteristics and potential biomarkers of DTP cells.
• Discussion of therapeutic strategies targeting DTP cell vulnerabilities.

Main Results:

• DTP cells represent a non-genetically altered population contributing to treatment resistance in both bacterial and cancer contexts.
• Understanding DTP cell biology is crucial for developing novel therapeutic approaches.
• Specific vulnerabilities and biomarkers for DTP cells are emerging areas of research.

Conclusions:

• DTP cells pose a significant challenge to effective cancer treatment due to their inherent resistance mechanisms.
• Further research into DTP cell biology, biomarkers, and vulnerabilities is essential for clinical translation.
• Targeting DTP cells holds promise for overcoming treatment resistance and improving patient outcomes in oncology.
