Abstract:
Retinoblastoma (Rb) is the most common ocular pediatric malignancy that arises from the retina and is caused by a mutation of the two alleles of the tumor suppressor gene, RB1. Although early detection provides the opportunity of controlling the primary tumor with effective therapies, metastatic activity is fatal. Non-coding RNAs (ncRNAs) have emerged as important modifiers of a plethora of biological mechanisms including those involved in cancer. They are classified into short and long ncRNAs according to their length. Deregulation of all these molecules has also been shown to play a critical role in Rb pathogenesis and progression. It is believed that ncRNAs can provide new insights into novel regulatory mechanisms associated with clinical pathological characteristics, facilitating the development of therapeutic alternatives for the treatment of Rb. In this review, we describe a variety of ncRNAs, which capable of regulating the most likely candidate genes involved in the tumorigenesis of Rb, could prove useful in analyzing different aspects of this cancer.
Insights
Retinoblastoma, a pediatric eye cancer, involves the RB1 gene. Non-coding RNAs (ncRNAs) are key in its development and progression, offering potential new therapeutic targets.
Area of Science:
- Oncology
- Genetics
- Molecular Biology
Background:
- Retinoblastoma (Rb) is the most frequent pediatric ocular cancer, originating in the retina.
- Rb is caused by mutations in both alleles of the RB1 tumor suppressor gene.
- While early detection aids primary tumor control, metastatic Rb is often fatal.
Purpose of the Study:
- To review the role of non-coding RNAs (ncRNAs) in Retinoblastoma pathogenesis and progression.
- To explore how ncRNAs regulate genes involved in Rb tumorigenesis.
- To highlight the potential of ncRNAs as biomarkers and therapeutic targets for Rb.
Main Methods:
- Literature review of studies on ncRNAs and Retinoblastoma.
- Analysis of ncRNA classification (short and long) and their regulatory functions.
- Examination of the association between ncRNA deregulation and clinical pathological characteristics of Rb.
Main Results:
- Non-coding RNAs (ncRNAs) significantly influence biological mechanisms, including cancer.
- Deregulation of ncRNAs plays a critical role in Rb pathogenesis and progression.
- ncRNAs have the potential to regulate key genes involved in Rb tumorigenesis.
Conclusions:
- ncRNAs offer novel insights into regulatory mechanisms in Rb.
- ncRNAs may serve as valuable tools for analyzing Rb.
- ncRNAs could facilitate the development of new therapeutic strategies for Retinoblastoma.

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,...
