Special Issue Information

Dear Colleagues,

We are pleased to announce a new Special Issue of Current Issues in Molecular Biology that aims to explore the cellular and molecular mechanisms involved in the development and progression of both non-alcoholic fatty liver disease (NAFLD) and alcohol-associated liver disease (ALD).

NAFLD and ALD are significant contributors to the global burden of liver disease. NAFLD, often associated with metabolic syndrome, obesity, diabetes, and cardiovascular disease, has emerged as the most common cause of chronic liver disease worldwide. ALD, on the other hand, is primarily caused by excessive alcohol consumption and encompasses a wide range of liver conditions, including steatosis, alcoholic steatohepatitis, cirrhosis, and hepatocellular carcinoma. NAFLD and ALD are both steatohepatitic processes and share several common features, yet they differ in many aspects. Therefore, understanding the development and progression of both NAFLD and ALD, in addition to uncovering the underlying cellular and molecular mechanisms, is crucial to advancing our knowledge and developing effective therapeutic strategies for the treatment of these liver diseases.

In this Special Issue, we welcome articles that investigate or summarize the cellular and molecular mechanisms that contribute to the pathogenesis and progression of NAFLD, NASH, ALD, and related diseases. We encourage researchers to explore a broad range of topics, including, but not limited to, impaired lipid metabolism, inflammation, oxidative stress, insulin resistance, genetic/epigenetic modifications, and the interplay between alcohol metabolism and liver injury.

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. Current Issues in Molecular Biology 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 2200 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.

RNA methylation plays a critical role in regulating all aspects of RNA function, which are implicated in the pathogenesis of various human diseases. Recent studies emphasize the role of 5-methylcytosine (m5C), an RNA modification, in key biological functions. Metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as the leading chronic liver condition globally. However, the relationship between m5C methylation and MASLD remains unclear. This study aimed to investigate m5C modification in a mouse model of MASLD. In this research, using RNA transcriptome sequencing (RNA-Seq) and methylated RNA bisulfite sequencing (RNA-BS-Seq) in leptin receptor-deficient mice, we found that genes associated with hypermethylation were primarily linked to lipid metabolism. We identified 156 overlapping and differentially expressed genes (DEGs) that changed at both the mRNA expression level and the m5C modification level. Among them, 72 genes showed elevated expression and m5C modification. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses indicated that these genes were significantly associated with lipid metabolism-related signaling pathways. Our results demonstrate that m5C methylation modifications may play an important role in the development of MASLD. Full article
