Special Issue Information

Dear Colleagues,

Epigenetic mechanisms are crucial for the proper development and maintenance of tissue-specific gene expression patterns in mammals. Epigenetic modifications, such as changes in DNA methylation, RNA modifications, and histone alterations, can result in the dysregulation of microRNA (miRNA) genes and malignant cellular transformation. These modifications are both heritable and reversible. Additionally, miRNAs can influence epigenetic-modifying enzymes, creating a three-way regulatory feedback loop known as “epi-miR-epi”. Modifying and reversing pathological miRNA expression holds promise for the development of therapeutic strategies.

This Special Issue is focused on “miRNAs in Cancers: From Molecular Biology to Treatment”. We invite researchers to submit original research and review articles that explore the role of miRNAs in cancer development.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Oral lichen planus (OLP) is a chronic inflammatory disorder of the oral mucosa with a recognized risk of malignant transformation. MicroRNAs, particularly miRNA-21 and miRNA-27b, have been implicated in the pathogenesis and progression of various diseases, including OLP. Their altered expression in saliva may provide diagnostic and prognostic insights for this condition. This systematic review examines the expression profiles of miRNA-21 and miRNA-27b in the saliva of OLP patients to assess their potential as biomarkers. The review was conducted in accordance with PRISMA guidelines and was registered in the PROSPERO database. A comprehensive search was conducted in PubMed, Embase, and Scopus using specific keywords. Retrieved titles and abstracts were screened based on predefined eligibility criteria, and relevant studies were analyzed. The initial search identified 71 studies. After screening, 17 abstracts were selected for full-text review. Following evaluation, 11 studies were excluded, resulting in 6 studies being included. Findings indicate a consistent upregulation of miRNA-21 and a downregulation of miRNA-27b in OLP saliva samples. These alterations suggest a potential role in disease pathogenesis and risk assessment. The dysregulation of miRNA-21 and miRNA-27b in OLP underscores their potential as salivary biomarkers for diagnosis and disease monitoring. Moreover, the non-invasive nature of salivary miRNAs offers promising clinical applications, enhancing early detection and personalized management strategies for OLP. Full article
