Abstract
Purpose: This narrative review aims to summarize current evidence on antisense oligonucleotide (ASO)-based strategies targeting oncogenic long non-coding RNAs (lncRNAs) and to evaluate their therapeutic potential in cancer initiation, progression, metastasis, and treatment resistance.
Methods: A narrative review of preclinical studies was conducted, focusing on ASO-mediated silencing of cancer-associated lncRNAs, including MALAT1, PVT1, NEAT1, and other emerging lncRNAs, across multiple malignancies such as lung, breast, ovarian, gastrointestinal, and head-and-neck cancers. Advances in ASO chemical design and delivery strategies-including lipid and polymeric nanoparticles, ligand-directed conjugates, peptide-based carriers, and gymnotic uptake-were also examined.
Results: Preclinical evidence consistently demonstrates that lncRNA-targeted ASOs effectively suppress tumor growth, invasion, metastasis, and chemoresistance while promoting apoptosis. Improvements in ASO chemical modifications and delivery platforms have significantly enhanced ASO stability, biodistribution, and intracellular uptake, thereby improving therapeutic efficacy across diverse cancer models.
Conclusion: Targeting oncogenic lncRNAs using ASO-based approaches represents a promising and rapidly evolving strategy in precision oncology. Although substantial progress has been achieved in ASO design and delivery, further optimization and well-structured clinical trials are required to facilitate the translation of these therapies into routine cancer treatment.
期刊介绍：
Biotechnology Letters is the world’s leading rapid-publication primary journal dedicated to biotechnology as a whole – that is to topics relating to actual or potential applications of biological reactions affected by microbial, plant or animal cells and biocatalysts derived from them.
All relevant aspects of molecular biology, genetics and cell biochemistry, of process and reactor design, of pre- and post-treatment steps, and of manufacturing or service operations are therefore included.
Contributions from industrial and academic laboratories are equally welcome. We also welcome contributions covering biotechnological aspects of regenerative medicine and biomaterials and also cancer biotechnology. Criteria for the acceptance of papers relate to our aim of publishing useful and informative results that will be of value to other workers in related fields.
The emphasis is very much on novelty and immediacy in order to justify rapid publication of authors’ results. It should be noted, however, that we do not normally publish papers (but this is not absolute) that deal with unidentified consortia of microorganisms (e.g. as in activated sludge) as these results may not be easily reproducible in other laboratories.
Papers describing the isolation and identification of microorganisms are not regarded as appropriate but such information can be appended as supporting information to a paper. Papers dealing with simple process development are usually considered to lack sufficient novelty or interest to warrant publication.
