Abstract:
Esophageal cancer (EC) is a serious digestive malignancy and is a leading cause of cancer-related mortality. Apart from genetic mutations, many epigenetic alterations including DNA methylation and histone modifications associated with chromatin remodeling have been identified in the regulation of gene expression in EC. Recently, noncoding RNAs, and mainly lncRNAs and miRNAs, have been revealed to be involved in the epigenetic regulation of EC. In this review, we focus on describing new insights on epigenetic processes associated with noncoding RNAs, which have been characterized to be responsible for the development and progression of EC.
Insights
Noncoding RNAs, like long noncoding RNAs (lncRNAs) and microRNAs (miRNAs), play a key role in the epigenetic regulation of esophageal cancer (EC). This review highlights their involvement in EC development and progression.
Area of Science:
- Oncology
- Epigenetics
- Molecular Biology
Background:
- Esophageal cancer (EC) is a significant cause of cancer mortality.
- Epigenetic alterations, including DNA methylation and histone modifications, are implicated in EC gene expression.
- Noncoding RNAs (ncRNAs) are emerging as critical players in EC's epigenetic landscape.
Purpose of the Study:
- To review recent advancements in understanding the epigenetic roles of noncoding RNAs in esophageal cancer.
- To elucidate how lncRNAs and miRNAs contribute to EC development and progression through epigenetic mechanisms.
Main Methods:
- Literature review focusing on recent studies.
- Analysis of research on noncoding RNA functions in esophageal cancer epigenetics.
- Synthesis of findings on DNA methylation, histone modifications, and ncRNA interactions.
Main Results:
- Noncoding RNAs, particularly lncRNAs and miRNAs, are integral to epigenetic regulation in EC.
- These ncRNAs influence gene expression patterns critical for EC pathogenesis.
- Specific ncRNAs have been identified as key mediators of epigenetic changes in EC.
Conclusions:
- Noncoding RNAs represent a crucial layer of epigenetic control in esophageal cancer.
- Targeting ncRNA-mediated epigenetic pathways offers potential therapeutic strategies for EC.
- Further research into ncRNA-epigenetic interactions is vital for advancing EC treatment.
