Abstract:
Splicing of mRNA precursor (pre-mRNA) is a mechanism to generate multiple mRNA isoforms from a single pre-mRNA, and it plays an essential role in a variety of biological phenomena and diseases such as cancers. Previous studies have demonstrated that cancer-specific splicing events are involved in various aspects of cancers such as proliferation, migration and response to hormones, suggesting that splicing-targeting therapy can be promising as a new strategy for cancer treatment. In this review, we focus on the splicing regulation by RNA-binding proteins including Drosophila behavior/human splicing (DBHS) family proteins, serine/arginine-rich (SR) proteins and heterogeneous nuclear ribonucleoproteins (hnRNPs) in hormone-related cancers, such as breast and prostate cancers.
Insights
Messenger RNA (mRNA) splicing generates diverse protein isoforms, crucial in cancer development. Targeting splicing mechanisms offers a promising new cancer therapy strategy, particularly for hormone-related cancers.
Area of Science:
- Molecular Biology
- Cancer Research
- Genetics
Background:
- Alternative splicing of messenger RNA precursors (pre-mRNA) generates multiple mRNA isoforms from a single gene.
- Aberrant splicing is implicated in various cancers, influencing proliferation, migration, and hormone response.
- Splicing-targeting therapies represent a novel and promising strategy for cancer treatment.
Purpose of the Study:
- To review the role of RNA-binding proteins in regulating splicing events.
- To focus on splicing regulation in hormone-related cancers like breast and prostate cancer.
- To highlight the potential of splicing-targeting therapies.
Main Methods:
- Review of existing scientific literature on mRNA splicing and cancer.
- Analysis of the roles of specific RNA-binding protein families (DBHS, SR proteins, hnRNPs).
- Focus on splicing alterations in hormone-dependent cancers.
Main Results:
- Cancer-specific splicing events are integral to cancer progression.
- RNA-binding proteins, including DBHS, SR proteins, and hnRNPs, are key regulators of these splicing events.
- Dysregulated splicing in hormone-related cancers impacts key biological processes.
Conclusions:
- Splicing regulation by RNA-binding proteins is critical in hormone-related cancers.
- Understanding these mechanisms can lead to the development of targeted cancer therapies.
- Splicing-targeting strategies hold significant therapeutic potential for breast and prostate cancers.
