Abstract:
Multiple studies have demonstrated chemoresistance in multiple types of tumor, which limits the effectiveness of cancer treatments. Chemoresistance often contributes to cancer relapse. Non‑coding RNAs, are a group of regulatory RNAs, that are involved in tumor drug resistance. Exosomes, membranous vesicles secreted by cells, are reported to mediate cell‑to‑cell communication, including in cancer. Furthermore, exosomal non‑coding RNAs have been reported to mediate chemoresistance via exchange of biological information. In the present review, the main roles of exosomal non‑coding RNAs, including micro(mi) RNAs, long non‑coding (lnc) RNAs, and circular (circ) RNAs in cancer are described and their potential roles in chemoresistance in various types of cancer are also discussed.
Insights
Non-coding RNAs within exosomes play a crucial role in mediating chemoresistance in various cancers. Understanding these exosomal non-coding RNAs (ncRNAs) is key to overcoming drug resistance and improving cancer treatment outcomes.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Chemoresistance limits cancer treatment efficacy and often leads to relapse.
- Non-coding RNAs (ncRNAs) are regulatory molecules implicated in tumor drug resistance.
- Exosomes facilitate cell-to-cell communication, transferring biological information, including ncRNAs.
Purpose of the Study:
- To review the roles of exosomal ncRNAs in cancer.
- To discuss the involvement of exosomal microRNAs, long non-coding RNAs, and circular RNAs in chemoresistance.
- To highlight the potential of targeting exosomal ncRNAs for overcoming cancer drug resistance.
Main Methods:
- Literature review of studies on exosomal ncRNAs and chemoresistance.
- Analysis of the mechanisms by which exosomal ncRNAs mediate drug resistance.
- Synthesis of current knowledge on microRNAs, lncRNAs, and circRNAs in exosomal communication.
Main Results:
- Exosomal ncRNAs, including miRNAs, lncRNAs, and circRNAs, are key mediators of intercellular communication in cancer.
- These exosomal ncRNAs can be transferred between cancer cells, influencing their drug response.
- Specific exosomal ncRNAs have been identified that promote or inhibit chemoresistance in various tumor types.
Conclusions:
- Exosomal non-coding RNAs represent a significant mechanism driving chemoresistance in cancer.
- Targeting the exchange of these exosomal ncRNAs offers a promising therapeutic strategy to combat cancer drug resistance.
- Further research into exosomal ncRNA function is crucial for developing novel cancer treatment approaches.
