Abstract:
Drug resistance is one of the most critical challenges facing researchers in treating breast cancer. Despite numerous treatments for breast cancer, including conventional chemical drugs, monoclonal antibodies, and immunotherapeutic drugs known as immune checkpoint inhibitors (ICI), many patients resist various approaches. In recent years, the relationship between gene expression profiles and drug resistance phenotypes has attracted much attention. Non-coding RNAs (ncRNAs) are regulatory molecules that have been shown to regulate gene expression and cell transcriptome. Two categories, microRNAs and long non-coding RNAs have been more considered and studied among these ncRNAs. Studying the role of different ncRNAs in chemical drug resistance and ICI resistance together can be beneficial in selecting more effective treatments for breast cancer. Changing the expression and action mechanism of these regulatory molecules on drug resistance phenotypes is the main topic of this review article.
Insights
Drug resistance in breast cancer is a major hurdle. This review explores how non-coding RNAs (ncRNAs) influence resistance to chemical drugs and immune checkpoint inhibitors (ICIs), offering insights for better treatment strategies.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Drug resistance presents a significant challenge in breast cancer treatment, limiting the efficacy of conventional therapies, monoclonal antibodies, and immune checkpoint inhibitors (ICIs).
- Understanding the molecular mechanisms underlying drug resistance is crucial for developing more effective therapeutic strategies.
- Non-coding RNAs (ncRNAs) have emerged as key regulators of gene expression and cellular processes, potentially playing a role in drug resistance phenotypes.
Purpose of the Study:
- To review the current understanding of non-coding RNAs (ncRNAs) in the context of breast cancer drug resistance.
- To investigate the role of microRNAs and long non-coding RNAs in resistance to both chemical drugs and immune checkpoint inhibitors (ICIs).
- To highlight the potential of targeting ncRNAs for overcoming treatment resistance in breast cancer.
Main Methods:
- Literature review of studies investigating ncRNAs and drug resistance in breast cancer.
- Analysis of research focusing on microRNAs and long non-coding RNAs.
- Synthesis of findings related to chemical drug resistance and ICI resistance.
Main Results:
- Non-coding RNAs (ncRNAs), including microRNAs and long non-coding RNAs, are implicated in regulating gene expression profiles associated with drug resistance.
- Altered expression and mechanisms of ncRNAs contribute to resistance against various breast cancer treatments.
- Studying ncRNAs collectively for both chemical and ICI resistance provides a comprehensive view of their regulatory roles.
Conclusions:
- Non-coding RNAs (ncRNAs) are critical regulators in breast cancer drug resistance.
- Targeting specific ncRNAs may offer novel therapeutic avenues to overcome resistance to chemical drugs and ICIs.
