Research ArticleOpen accessIn the abstractQuantitative Analysis of Hypothalamic Proline-Rich Peptide-1 in Blood Serum of Patients with Malignant TumorsNarine Tumasyan, Silva Abrahamyan, Nune Kocharyan et al.The proline-rich-peptides are a class of neurosecretory hypothalamic bioactive polypeptides derived from cattle and comprise the content of bovine posterior pituitary neurosecretory granules. These peptides are co-validated through a single precursor protein neurophysin-vasopressin-associated glycoprotein. Proline-Rich-Polypeptide-1 (PRP-1) is a 15-amino acid peptide with anti-neurodegenerative, immunoregulatory, hematopoietic, antimicrobial, and antitumor activity. The aim of this study, accordingly, is to elaborate an assay … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 27 Nov 2025 · 2,287 accessesView PDFCite

Research ArticleOpen accessIn the abstractsuPAR as an Inflammatory and Preclinical Atherosclerotic Marker in Hypovitaminosis DShravan Ajith Panchwadkar, Sudha Kuthethur, Neelam Manjunath Pawar et al.The mechanistic link between inflammation and atherosclerosis highlights the critical role of immune modulation in cardiovascular disease. The soluble urokinase plasminogen activator receptor (suPAR), an immune-derived factor, has recently emerged as a non-specific inflammatory marker across chronic diseases and infections. All cells within the atherosclerotic arterial wall can express uPAR and release urokinase, which plays a key role in the … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 30 Mar 2026 · 1,126 accessesView PDFCite
