Abstract:
miR-145-5p is a microRNA whose role in diverse disorders has been verified. This miRNA is encoded by MIR145 gene on chromosome 5. This miRNA is mainly considered as a tumor suppressor miRNA in diverse types of cancers, including bladder cancer, breast cancer, cervical cancer, cholangiocarcinoma, renal cancer, and gastrointestinal cancers. However, few studies have reported up-regulation of this miRNA in some cancers. Moreover, it has been shown to affect pathogenesis of a number of non-malignant conditions such as aplastic anemia, asthma, cerebral ischemia/reperfusion injury, diabetic nephropathy, rheumatoid arthritis and Sjögren syndrome. In the current review, we summarize the available literature about the role of miR-145-5p in these conditions.
Insights
MicroRNA-145-5p (miR-145-5p) acts as a tumor suppressor in many cancers but can be upregulated in others. This microRNA also impacts non-malignant conditions like asthma and arthritis.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNA-145-5p (miR-145-5p), encoded by the MIR145 gene on chromosome 5, is implicated in various diseases.
- It is primarily recognized as a tumor suppressor in multiple cancers, including bladder, breast, cervical, cholangiocarcinoma, renal, and gastrointestinal cancers.
Purpose of the Study:
- To review the current literature on the multifaceted roles of miR-145-5p.
- To consolidate understanding of its involvement in both malignant and non-malignant conditions.
Main Methods:
- Literature review of studies investigating miR-145-5p.
- Analysis of its expression patterns and functional roles in disease pathogenesis.
Main Results:
- miR-145-5p generally functions as a tumor suppressor, but its upregulation has been observed in certain cancers.
- Evidence suggests miR-145-5p influences the pathogenesis of non-malignant conditions such as aplastic anemia, asthma, cerebral ischemia/reperfusion injury, diabetic nephropathy, rheumatoid arthritis, and Sjögren syndrome.
Conclusions:
- miR-145-5p exhibits complex roles in disease, acting as a tumor suppressor in many cancers while also affecting non-malignant disorders.
- Further research is warranted to fully elucidate the therapeutic potential of targeting miR-145-5p.
