Article Abstract
Purpose: The receptor for advanced glycation end products (RAGE) upregulated during the onset and progression of cancer and bone-related pathologies. In this study, we aimed to investigate the role of serum advanced glycation end products (AGEs), soluble RAGE (sRAGE) and high mobility group box 1 (HMGB1), in multiple myeloma (MM).
Methods: AGEs, sRAGE and HMGB1 concentrations of 54 newly diagnosed MM patients and 30 healthy volunteers were measured by ELISA. The estimations were done only once at diagnosis. The medical records of the patients were evaluated.
Results: There was no significant difference between the AGEs and sRAGE levels between the patient and control groups (p = 0.273, p = 0.313). In ROC analysis, a HMGB1 cutoff value of > 9170 pg/ml accurately discriminated MM patients (AUC = 0.672, 95% CI 0.561-0.77, p = 0.0034). AGEs level was found to be significantly higher in early-stage disease and HMGB1 in advanced disease (p = 0.022, p = 0.026). High HMGB1 levels were detected in patients whose with better first-line treatment response (p = 0.019). At 36 months, 54% of patients with low AGE were alive, compared to 79% of patients with high AGE (p = 0.055). Patients with high HMGB1 levels tended to have a longer PFS (median 43 mo [95% CI; 20.68-65.31] ) compared to patients with low HMGB1 levels (median 25 mo [95% CI; 12.39-37.6], p = 0.054).
Conclusion: In this study, a significant elevation of serum HMGB1 level was found in MM patients. In addition, the positive effects of RAGE ligands on treatment response and prognosis were determined.

: Polycystic ovary syndrome (PCOS) is an endocrine disorder characterized by metabolic and hormonal imbalances in women of reproductive age. Various studies have emphasized that a diet high in advanced glycation end products (AGEs) and high serum AGE levels may be associated with reproductive and metabolic dysfunction in PCOS. Recently, the role played by dietary and serum AGE levels in the pathogenesis of PCOS was emphasized.

Unlabelled: In diabetes- and age-related osteopenia/osteoporosis, a pathogenetic role of advanced glycation end-products and their soluble receptors (RAGE) is implicated. We studied how these compounds relate to bone health in girls with anorexia nervosa. We found that higher levels of endogenous secretory RAGE were associated with poorer bone quality, warranting further research.

Advanced glycation end-products (AGEs) are formed by the non-enzymatic glycation of proteins, lipids, and nucleic acids due to the consumption of high-carbohydrate diets; their production is also promoted by a sedentary lifestyle as well as cigarette smoking. Elevated levels of AGEs in the circulatory system and internal organs of the body are commonly observed in a number of cardiovascular diseases such as hypertension, diabetes, atherosclerosis, coronary artery disease, aortic aneurysm, atrial fibrillation, myocardial infarction, and heart failure, which are associated with the development of oxidative stress and myocardial inflammation. The adverse effects of AGEs on the cardiovascular system are elicited by both non-receptor mechanisms involving the cross-linking of extracellular and intracellular proteins, and by receptor-mediated mechanisms involving the binding of AGEs with advanced glycation end-product receptors (RAGEs) on the cell membrane.

Telomere attrition stands as a fundamental hallmark of cardiovascular aging, driving cellular senescence and dysfunction across endothelial, cardiomyocyte, and vascular smooth muscle compartments. This review systematically examines: (1) molecular mechanisms linking telomere shortening to oxidative stress (NOX2/PRDX1 axis), epigenetic dysregulation (subtelomeric methylation, H3K9me3 loss), and mitochondrial dysfunction; (2) clinical evidence positioning leukocyte telomere length and telomere-associated proteins (eg, TRF2, POT1) as predictive biomarkers for coronary artery disease, heart failure, and hypertension; and (3) emerging therapeutic strategies ranging from telomerase activation (TA-65, GRN510) to senolytic cocktails (dasatinib + quercetin) and CRISPR (regularly interspersed short palindromic reportsclustered regularly interspaced short palindromic repeats)-based editing (6-29% efficiency in Chinese hamster ovary models). The review further addresses methodological challenges in telomere measurement (quantitative polymerase chain reaction (PCR) vs Flow-FISH standardization) and proposes an integrated risk assessment model combining leukocyte telomere length, oxidative markers (AGEs/sRAGE ratio), and epigenetic clocks.

Systemic lupus erythematosus (SLE) is a multifaceted autoimmune disease with a heterogeneous organ involvement, for which reliable biomarkers are still being studied. The implication of advanced glycation end products (AGEs), resulting from oxidative stress, and their interaction with the receptor for AGEs (RAGE) has been studied in pathologies with chronic proinflammatory status, offering potential relevance in SLE. This systematic review aimed to evaluate the utility of skin autofluorescence (SAF)-a non-invasive proxy for AGE accumulation-as a biomarker for disease severity, activity, and impact in SLE patients.
