Special Issue Information

Dear Colleagues,

Increasing scientific evidence confirms that the combination of reactive oxygen species (ROS) overproduction, oxidative stress (OS), and hyperinflammation can cause endothelial layer damage, which eventually leads to endothelial dysfunction. Oxidative stress occurs due to the imbalance between the production of ROS and the availability of antioxidants or radical scavengers. The excess ROS produced can either oxidize biomolecules or structurally modify lipids, proteins, and genes to trigger signaling cascades, leading to the onset and progression of inflammatory diseases. Inflammation causes immune cells to secrete various cytokines and chemokines to recruit other immune cells to the site of oxidative stress/infection. Reflexively, enhanced ROS generation by immune cells at the site of inflammation causes oxidative stress and tissue injury. The inflammatory-initiated endothelial dysfunction can promote chronic inflammation, thrombosis, atherosclerosis, and lung injury. The generation of a large amount of mitochondrial reactive oxygen species (mtROS) and their excess causes OS, which can promote inflammation and cause chronic endothelial dysfunction.

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.

Dysregulated miR-21/SOD3, but Not miR-30b/CAT, Profile in Elderly Patients with Carbohydrate Metabolism Disorders: A Link to Oxidative Stress and Metabolic Dysfunction

Carbohydrate metabolism disorders (CMDs), including prediabetes and type 2 diabetes mellitus (T2DM), are increasingly prevalent in the aging population. Oxidative stress (OxS) plays a pivotal role in CMD pathogenesis, with extracellular superoxide dismutase (SOD3) and catalase (CAT) serving as critical antioxidant defenses. Additionally, microRNAs (miR-21 and miR-30b) regulate the oxidative and inflammatory pathways, yet their roles in elderly CMD patients remain unclear. This study evaluated miR-21 and miR-30b expression alongside SOD3 and CAT plasma levels in individuals aged ≥ 65 years (n = 126) categorized into control (n = 38), prediabetes (n = 37), and T2DM (n = 51) groups. Quantitative PCR assessed miRNA expression, while ELISA measured the enzyme levels. SOD3 levels were significantly reduced in CMDs, particularly in T2DM, whereas miR-21 was upregulated. A negative correlation between SOD3 and miR-21 was strongest in T2DM, suggesting a regulatory interplay. Neither CAT levels nor miR-30b expression differed among groups. Logistic regression indicated SOD3 as a protective biomarker, with each 1 ng/mL increase reducing the CMD risk by ~5–6%. The ROC analysis supported SOD3’s diagnostic potential, while miR-21 showed a modest association. These findings highlight SOD3 downregulation and miR-21 upregulation as potential contributors to CMD progression in elderly patients, warranting further research into their mechanistic roles and therapeutic potential.
