Abstract:
Downregulated expression of anti-tumor miR-383 has been found in many kinds of cancer. MiR-383 family members can directly target the 3'-untranslated region (3'-UTR) of the mRNA of some pro-tumor genes to attenuate several cancer-related processes, including cell proliferation, invasion, migration, angiogenesis, immunosuppression, epithelial-mesenchymal transition, glycolysis, chemoresistance, and the development of cancer stem cells, whilst promoting apoptosis. Functionally, miR-383 operates as a tumor inhibitor miRNA in many types of cancer, including breast cancer, hepatocellular carcinoma, gastric cancer, pancreatic cancer, colorectal cancer, esophageal cancer, lung cancer, head and neck cancer, glioma, medulloblastoma, melanoma, prostate cancer, cervical cancer, oral squamous cell carcinoma, thyroid cancer, and B-cell lymphoma. Both pro-tumor and anti-tumor effects have been attributed to miR-383 in ovarian cancer. However, only the pro-tumor effects of miR-383 were reported in cholangiocarcinoma. The restoration of miR-383 expression could be considered a possible treatment for cancer. This review discusses the anti-tumor effects of miR-383 in human cancers, emphasizing their downstream target genes and potential treatment approaches.
Insights
MicroRNA-383 (miR-383) acts as a tumor suppressor by inhibiting cancer cell growth and promoting apoptosis. Restoring miR-383 expression shows potential as a novel cancer therapy.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Downregulated expression of miR-383 is observed in numerous human cancers.
- miR-383 functions as a tumor suppressor miRNA, inhibiting key oncogenic pathways.
Purpose of the Study:
- To review the anti-tumor effects of miR-383 across various human cancers.
- To highlight miR-383's downstream target genes and potential therapeutic applications.
Main Methods:
- Literature review of studies investigating miR-383 in cancer.
- Analysis of miR-383's targeting mechanisms and functional roles.
Main Results:
- miR-383 inhibits cancer cell proliferation, invasion, migration, angiogenesis, and chemoresistance.
- It also suppresses epithelial-mesenchymal transition, glycolysis, and cancer stem cell development, while promoting apoptosis.
- miR-383 exhibits tumor-inhibitory roles in breast, lung, colorectal, and many other cancers, with exceptions in ovarian and cholangiocarcinoma.
