Abstract:
Retinoblastoma represents 3% of all childhood cancers and is the most common intraocular malignant tumor with a highly aggressive and metastatic phenotype. While recent genetic and epigenetic studies have reported new insights into the mechanism of retinoblastoma development, the involvement of regulatory non-coding RNAs remains unclear. Long non-coding RNAs (lncRNAs) are a group of endogenous non-protein-coding RNAs with the capacity to regulate gene expression at multiple levels. Recent evidence has shown that lncRNAs can regulate many cellular processes, such as cell proliferation, differentiation, migration, and invasion. Several lncRNAs, including BANCR, AFAP1-AS1, NEAT1, XIST, ANRIL, PlncRNA-1, HOTAIR, PANDAR, DANCR, and THOR, promote the progression and metastasis of retinoblastoma. However, some lncRNAs, such as MEG3, MT1JP, and H19, play a tumor suppressive role. Our review summarizes the functional role of lncRNAs in retinoblastoma and their potential clinical applications for diagnosis, prognosis, and treatment.
Insights
Long non-coding RNAs (lncRNAs) are key regulators in retinoblastoma, influencing its aggressive nature. This review explores their roles in cancer progression and potential as diagnostic and therapeutic targets.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Retinoblastoma is a common childhood cancer with aggressive metastatic potential.
- While genetic factors are studied, the role of regulatory non-coding RNAs in retinoblastoma remains largely unexplored.
- Long non-coding RNAs (lncRNAs) are critical regulators of gene expression involved in various cellular processes.
Purpose of the Study:
- To review the functional roles of lncRNAs in retinoblastoma development and progression.
- To explore the dual role of specific lncRNAs as oncogenes or tumor suppressors in retinoblastoma.
- To discuss the potential clinical applications of lncRNAs in retinoblastoma diagnosis, prognosis, and treatment.
Main Methods:
- Literature review of studies investigating lncRNAs in retinoblastoma.
- Analysis of identified lncRNAs promoting or suppressing retinoblastoma progression.
- Synthesis of current knowledge on lncRNA mechanisms in retinoblastoma.
Main Results:
- Multiple lncRNAs (e.g., BANCR, HOTAIR) promote retinoblastoma progression and metastasis.
- Other lncRNAs (e.g., MEG3, H19) exhibit tumor-suppressive functions in retinoblastoma.
- lncRNAs regulate key cellular processes including proliferation, migration, and invasion in retinoblastoma cells.
Conclusions:
- lncRNAs play significant, multifaceted roles in retinoblastoma.
- lncRNAs represent promising biomarkers for retinoblastoma diagnosis and prognosis.
- Targeting lncRNAs may offer novel therapeutic strategies for retinoblastoma treatment.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
