Abstract:
Long non-coding RNAs (lncRNAs), with transcript lengths exceeding 200 nucleotides and little or no protein-coding capacity, have been found to impact colorectal cancer (CRC) through various biological processes. LncRNA expression can regulate autophagy, which plays dual roles in the initiation and progression of cancers, including CRC. Abnormal expression of lncRNAs is associated with the emergence of chemoresistance. Moreover, it has been confirmed that targeting autophagy through lncRNA regulation could be a viable approach for combating chemoresistance. Two recent studies titled "Human β-defensin-1 affects the mammalian target of rapamycin pathway and autophagy in colon cancer cells through long non-coding RNA TCONS_00014506" and "Upregulated lncRNA PRNT promotes progression and oxaliplatin resistance of colorectal cancer cells by regulating HIPK2 transcription" revealed novel insights into lncRNAs associated with autophagy and oxaliplatin resistance in CRC, respectively. In this editorial, we particularly focus on the regulatory role of lncRNAs in CRC-related autophagy and chemoresistance since the regulation of chemotherapeutic sensitivity by intervening with the lncRNAs involved in the autophagy process has become a promising new approach for cancer treatment.
Insights
Long non-coding RNAs (lncRNAs) regulate autophagy and chemoresistance in colorectal cancer (CRC). Targeting lncRNAs offers a promising strategy to overcome drug resistance in CRC treatment.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Long non-coding RNAs (lncRNAs) are key regulators in various biological processes, including cancer development.
- lncRNA expression significantly influences autophagy, a cellular process with a dual role in cancer initiation and progression.
- Aberrant lncRNA expression is linked to the development of chemoresistance in colorectal cancer (CRC).
Discussion:
- lncRNAs modulate autophagy, presenting a potential therapeutic target for overcoming chemoresistance in CRC.
- Recent studies highlight specific lncRNAs (TCONS_00014506 and PRNT) involved in CRC cell autophagy and oxaliplatin resistance.
- Intervening with lncRNAs that regulate autophagy is emerging as a novel strategy to enhance chemotherapeutic sensitivity in CRC.
Key Insights:
- lncRNAs play a critical role in regulating autophagy in colorectal cancer.
- Specific lncRNAs are associated with chemoresistance, particularly to oxaliplatin, in CRC.
- Modulating lncRNA-mediated autophagy can potentially reverse or overcome chemoresistance in CRC.
Outlook:
- Further research into lncRNA-autophagy interactions could uncover new therapeutic targets for CRC.
- Developing lncRNA-based strategies to modulate autophagy may improve treatment outcomes for chemoresistant CRC.
- This approach holds promise for personalized medicine in colorectal cancer treatment by targeting specific lncRNA pathways.

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.
