Regulation of Cellular Signaling Pathways in the Metabolic Syndrome

Dear Colleagues,

Metabolic syndrome (MetS), which describes a cluster of interrelated conditions that includes central obesity, dyslipidemia, lipid resistance, hypertension, diabetes, and cancer, has become a global public health concern. The pathophysiology of MetS is tightly regulated by a complex network of cellular signaling pathways, including insulin-, AMPK-, MAPK-, mTOR-, PKA-, NF-κB-, and adipokine-mediated signaling, among others. These pathways coordinate metabolic processes such as glucose and lipid metabolism, inflammation, oxidative stress response, and mitochondrial function. Dysregulation of these signaling networks plays a central role in the onset and progression of MetS and its associated complications, including type 2 diabetes, cardiovascular disease, metabolic dysfunction-associated steatotic liver disease (MASLD), and many cancer types. A deeper mechanistic understanding of how these pathways are regulated—both under physiological and pathological conditions—may yield novel biomarkers and therapeutic targets.

Therefore, Life is pleased to announce this Special Issue titled “Regulation of Cellular Signaling Pathways in the Metabolic Syndrome”. This Special Issue aims to bring together cutting-edge research that enhances our understanding of how cellular signaling pathways contribute to the development, progression, and potential treatment of MetS. We invite original research articles, reviews, and short communications that explore the regulation, crosstalk, and therapeutic modulation of cellular signaling in the context of MetS.

Topics of interest include, but are not limited to, the following:

• Molecular mechanisms of insulin signaling and resistance in MetS;
• Crosstalk between nutrient-sensing pathways (e.g., AMPK, mTOR, and SIRT) in metabolic regulation.
• Role of inflammation and immune signaling (e.g., NF-κB and JAK-STAT) in adipose tissue dysfunction;
• Oxidative stress, mitochondrial signaling, and redox imbalance in metabolic disorders;
• Adipokine and cytokine signaling in obesity and MetS;
• ER stress and unfolded protein response pathways in metabolic regulation;
• Mechanisms by which hallmarks of MetS (e.g., increased IGF signaling, chronic inflammation, adipokine imbalance, oxidative stress, and hormonal changes) impact the etiology and progression of various cancers;
• Tissue-specific signaling dynamics in liver, muscle, adipose tissue, heart, and brain;
• Microbiota-derived metabolites and their influence on host signaling in MetS;
• Emerging therapeutic targets and pharmacological modulators of key signaling nodes;
• Systems biology and multi-omics approaches to signaling network analysis in MetS.

We look forward to your contributions.

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. Life 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.
