Abstract:
miRNAs are non-coding RNAs that bind to mRNA targets and disturb their stability and/or translation, thus acting in gene posttranscriptional regulation. It is predicted that over 30% of mRNAs are regulated by miRNAs. Therefore these molecules are considered essential in the processing of many biological responses, such as cell proliferation, apoptosis, and stress responsiveness. As miRNAs participate of virtually all cellular pathways, their deregulation is critical to cancer development. Consequently, loss or gain of miRNAs function may contribute to tumor progression. Little is known about the regulation of miRNAs and understanding the events that lead to changes in their expression may provide new perspectives for cancer treatment. Among distinct types of cancer, melanoma has special implications. It is characterized as a complex disease, originated from a malignant transformation of melanocytes. Despite being rare, its metastatic form is usually incurable, which makes melanoma the major death cause of all skin cancers. Some molecular pathways are frequently disrupted in melanoma, and miRNAs probably have a decisive role on these alterations. Therefore, this review aims to discuss new findings about miRNAs in melanoma fields, underlying epigenetic processes, and also to argue possibilities of using miRNAs in melanoma diagnosis and therapy.
Insights
MicroRNAs (miRNAs) regulate gene expression and are crucial in biological responses. This review explores their role in melanoma, focusing on epigenetic regulation for potential diagnosis and therapy.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNAs (miRNAs) are non-coding RNAs regulating gene posttranscriptional processes, impacting cell proliferation, apoptosis, and stress responses.
- Dysregulation of miRNAs is implicated in cancer development, with altered miRNA function potentially driving tumor progression.
- Melanoma, a complex skin cancer with a high mortality rate for metastatic forms, exhibits disrupted molecular pathways where miRNAs likely play a key role.
Purpose of the Study:
- To review recent findings on microRNAs in melanoma.
- To discuss epigenetic processes influencing miRNA expression in melanoma.
- To explore the potential of miRNAs in melanoma diagnosis and therapy.
Main Methods:
- Literature review of current research on miRNAs and melanoma.
- Analysis of epigenetic mechanisms affecting miRNA expression.
- Discussion of diagnostic and therapeutic applications of miRNAs in melanoma.
Main Results:
- miRNAs are critical regulators of gene expression and are involved in numerous cellular pathways.
