Special Issue Information

Dear Colleagues,

Whether men or women, various metabolic changes tend to occur after the age of 50 due to hormonal changes. Especially in women, hormonal changes, such as decreased levels of estrogen and increased levels of circulating androgens, can lead to the development of cardiovascular disease and metabolic syndrome, including type 2 diabetes. In women, estrogen deficiency can lead to a chronic inflammatory state, including increased proinflammatory cytokines, impaired Treg/Th17 cell balance, and impaired osteogenic differentiation capacity of bone marrow mesenchymal stem cells (BMSCs). Inadequate bone formation by BMSC-derived osteoblasts to compensate for bone resorption by osteoblasts is a major cause of osteoporosis in postmenopausal women. In men, a decrease in androgens and an increase in estrogen accelerate muscle loss and decrease basal metabolic rate, increasing the risk of abdominal obesity.

Metabolic syndrome is defined as a group of disorders characterized by impaired glucose metabolism, hypertension, central obesity, low LDL-C, and high triglyceride levels. It also promotes a chronic systemic inflammatory state characterized by glucose intolerance and immune cell infiltration, and this immune system activation increases the risk of serious illness following viral infection. Additionally, studies have been reported on the increase in diseases related to various metabolic diseases such as non-alcoholic fatty liver disease, psoriasis, and inflammatory bowel disease. Metabolic diseases tend to progress quietly and gradually rather than showing acute symptoms.

There is an urgent need for molecular biological research that can prevent and alleviate metabolic diseases caused by hormonal changes that naturally occur with aging.

We request the cooperation of fellow researchers to maintain a better quality of life.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

The inflammatory state is a significant factor associated with diabetic kidney disease (DKD), making it one of the significant causes of chronic kidney disease. Despite the availability of data, there is a lack of targeted treatment strategies for diabetes-related kidney disorders. The aim of our study was to determine the impact of cannabigerol (CBG) on lipid precursors for inflammatory mediators during DKD development. A six-week experiment was conducted on male Wistar rats fed standard (Control) or high-fat high-sucrose (HFHS) diets. For the last 14 days of the experiment (5th and 6th weeks), half of the rats from the Control and HFHS groups intragastrically received CBG solution. Gas–liquid chromatography (GLC) was used to measure the activities of n-6 and n-3 polyunsaturated fatty acid (PUFA) metabolic pathways and the concentrations of arachidonic acid (AA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) in selected lipid fractions. Immunoblotting was performed to assess the expression of proteins involved in the regulation of the inflammatory state. A multiplex immunoassay kit was used to determine kidney toxicity biomarker levels. Our results revealed that CBG administration to rats fed an HFHS diet decreased n-6 PUFA biosynthetic pathway activity in phospholipid (PL) and triacylglycerol (TAG) and increased n-3 PUFA biosynthetic pathway activity in TAG and free fatty acid (FFA). We also observed a reduction in the AA concentration in PL, FFA, and diacylglycerol (DAG). CBG supplementation reduced the level of kidney damage biomarkers, such as osteopontin (OPN). Our observations confirm that CBG has potential anti-inflammatory properties and may be successfully used for further research to seek targeted therapies of inflammatory disorders, including diabetic kidney disease progression.
