Abstract:
Colorectal cancer (CRC) is the third prevalent cancer worldwide, the morbidity and mortality of which have been increasing in recent years. As molecular targeting agents, anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (McAbs) have significantly increased the progression-free survival (PFS) and overall survival (OS) of metastatic CRC (mCRC) patients. Nevertheless, most patients are eventually resistant to anti-EGFR McAbs. With the intensive study of the mechanism of anti-EGFR drug resistance, a variety of biomarkers and pathways have been found to participate in CRC resistance to anti-EGFR therapy. More and more studies have implicated non-coding RNAs (ncRNAs) primarily including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), are widely involved in tumorigenesis and tumor progression. They function as essential regulators controlling the expression and function of oncogenes. Increasing data have shown ncRNAs affect the resistance of molecular targeted drugs in CRC including anti-EGFR McAbs. In this paper, we have reviewed the advance in mechanisms of ncRNAs in regulating anti-EGFR McAbs therapy resistance in CRC. It provides insight into exploring ncRNAs as new molecular targets and prognostic markers for CRC.
Insights
Non-coding RNAs (ncRNAs) are implicated in colorectal cancer (CRC) resistance to anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (McAbs). Understanding these ncRNAs offers new targets for improving CRC treatment outcomes.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Colorectal cancer (CRC) is a leading cause of cancer mortality worldwide, with increasing incidence.
- Anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (McAbs) have improved outcomes for metastatic CRC (mCRC), but resistance remains a significant challenge.
Purpose of the Study:
- To review the mechanisms by which non-coding RNAs (ncRNAs) regulate resistance to anti-EGFR McAbs in CRC.
- To highlight the potential of ncRNAs as biomarkers and therapeutic targets for overcoming anti-EGFR therapy resistance in CRC.
Main Methods:
- Literature review of studies investigating ncRNAs (miRNAs, lncRNAs, circRNAs) and their role in CRC.
- Analysis of ncRNA involvement in tumorigenesis, tumor progression, and drug resistance mechanisms.
Main Results:
- ncRNAs, including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), are key regulators of gene expression in CRC.
- These ncRNAs play a crucial role in the development of resistance to anti-EGFR McAbs in CRC patients.
- Specific ncRNAs have been identified as critical mediators of resistance pathways.
Conclusions:
- ncRNAs are integral to the mechanisms underlying CRC resistance to anti-EGFR therapy.
- Targeting ncRNAs presents a promising strategy for developing novel therapeutic approaches and prognostic markers for mCRC.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
