Special Issue Information
Dear Colleagues,
In late 2012, the ENCODE project results evidenced that most of the human genome is transcribed but that only a reduced proportion of these transcripts are translated. This observation, confirmed also in several other organisms, clearly supports a shift of paradigm in the role that RNAs are playing in many cellular processes: from a simple transporter of information from DNA to proteins to a regulatory molecule that can also be involved in the regulation of genome functions, such as in the case of XIST to silence the X chromosome in eukaryotes or in the case of the CRISPR-CAS system to break exogenous DNA in prokaryotes. It is now widely recognized that both short and long noncoding RNAs may have multiple regulatory functions by controlling nuclear architecture and transcription in the nucleus and by modulating mRNA stability, translation, and post-translational modifications in the cytoplasm. Given their broad functional potentials, the characterization of ncRNAs is still a challenging task. In this perspective, advanced computational approaches are essential in the preliminary screening phase to identify the most probable functions. Whatever their origin, size, structure, or function, it is evident that noncoding RNAs are a dynamic, active, and expanding family of necessary molecules, some of them with deep evolutionary history. They are established as appreciated biotechnological tools (e.g., siRNAs, miRNAs, CRISPR-CAS9) confirming that understanding their function has a great impact not only in basic but also in applied research.
The ENCODE project evidenced the functional importance of improperly defined junk DNA. In fact, also DNA regions not associated with protein coding genes can be transcribed to produce noncoding RNAs with no or limited translation capacity. Noncoding RNAs are becoming the major regulatory molecules to shape the phenotypic complexity and, in many cases, to guide cells in pathological states. This Special Issue is focused on, but not limited to, functions of different classes of noncoding RNAs in eukaryotes and prokaryotes. We invite the submission of both reviews and original research articles, including bioinformatic approaches to study variations in expression, post-transcriptional modifications, and the structure of noncoding RNAs, also considering single cell approaches.

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. Genes is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). 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.
