Special Issue Information

Dear Colleagues,

It will soon be 20 years since the advent of massively parallel sequencing (MPS) technology and the introduction of the first devices enabling the acquisition of large quantities of nucleic acid sequences in a relatively short time and at a low cost. Over these years, the technology has evolved, creating new research possibilities and becoming accessible to a broad community of researchers. As a result, sequence databases are expanding at an unprecedented rate. This technological revolution has also brought a widening range of applications for MPS techniques. An important aspect of this process is the diversity of available large-scale sequencing technologies, which allows for tailoring the chosen technology to the research objective and compiling data obtained using various technologies to enhance the quality of results or their validation.

The substantial progress in sequencing technology also underlies significant shifts in our understanding of processes occurring within living organisms, particularly at the molecular level. The ability to elucidate complete genome sequences or their selected segments, coupled with technologies enabling the analysis of the expression of entire gene sets and the detection of various types of polymorphisms, at both the single-nucleotide and whole-chromosome levels, has led to a proliferation of publications detailing the workings of specific molecular mechanisms underlying the functioning of living organisms.

Our aim in preparing this Special Issue is to compile scientific articles describing various aspects of the applications of large-scale sequencing technology in molecular biology research. We are particularly keen on presenting publications that showcase methods and experimental approaches that ingeniously and pioneeringly harness the potential of available devices, setting new trends in the utilization of MPS technology within the field of molecular biology.

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.

MicroRNAs (miRNAs) are small non-coding RNAs involved in gene regulation and are potential biomarkers for several diseases, including canine enteropathies. While metabolite profiling and microbiome in canine enteropathies have been previously explored, data on miRNA expression remain limited. This study aimed to profile miRNA expression in Yorkshire Terrier canine enteropathy using Illumina sequencing and quantitative PCR (qPCR) to compare miRNA levels between sick and healthy dogs from fecal samples. Despite the hypothesis that disease-related alterations in miRNA levels would differentiate sick dogs from controls, no significant differences were observed between the groups in either sequencing or qPCR analyses. These findings suggest that miRNA profiles may not vary significantly in the context of Yorkshire Terrier enteropathy and indicate that other molecular or metabolomic markers may be more indicative of disease state. This study also indicates that fecal samples may not be an ideal sample type for miRNA profiling. This study contributes to the understanding of molecular signatures in canine enteropathies and provides a basis for further research into alternative biomarkers for diagnosis and monitoring.
