What doesn't kill you makes you stranger: Dipeptidyl peptidase-4 (CD26) proteolysis differentially modulates the activity of many peptide hormones and cytokines generating novel cryptic bioactive ligands [PDF]

open access: yes, 2019
Dipeptidyl peptidase 4 (DPP4) is an exopeptidase found either on cell surfaces where it is highly regulated in terms of its expression and surface availability (CD26) or in a free/circulating soluble constitutively available and intrinsically active form.

SUMOylation regulates tumorigenesis and progression: Molecular mechanisms and therapeutic applications

open access: yesInterdisciplinary Medicine, EarlyView.
SUMOylation, a dynamic post‐translational modification, acts as a master regulator at the heart of tumor malignancy. Our work delineates how the SUMOylation cycle—mediated by E1/E2/E3 enzymes and reversed by SENPs—orchestrates multiple hallmarks of cancer. The central pathway converges on three critical pathological axes: 1.

A case-control analysis of common variants in GIP with type 2 diabetes and related biochemical parameters in a South Indian population [PDF]

open access: yes, 2010
Background Glucose-dependent insulinotropic polypeptide (GIP) is one of the incretins, which plays a crucial role in the secretion of insulin upon food stimulus and in the regulation of postprandial glucose level.

In silico prediction and structural characterization of multifunctional bioactive peptides released from olive proteins

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Olive (Olea europaea L.) byproducts, such as seeds and leaves, are abundant agro‐industrial residues and represent underexplored protein sources with potential health relevance. However, the repertoire of bioactive peptides that may be released from olive proteins during gastrointestinal digestion remains poorly characterized.

Glucagon-like peptide-1 (GLP-1) increases in plasma and colon tissue prior to estrus and circulating levels change with increasing age in reproductively competent Wistar rats

open access: yes, 2017

Metabolic Dysfunction‐Associated Steatotic Liver Disease and Obesity: Pathogenesis, Diagnostics, Risk Stratification, and Therapeutic Approach

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Metabolic dysfunction‐associated steatotic liver disease (MASLD) has emerged as the most prevalent chronic liver disease worldwide, closely linked to the global rising incidence of obesity and metabolic syndrome. This review synthesizes current evidence on the pathogenesis, gut–liver axis, and multidisciplinary management of MASLD within the ...

Diabetic Peripheral Neuropathy: Molecular Staging, Risk Factors, Therapeutics, and Emerging Trends

open access: yesMed Research, EarlyView.
The heterogeneous landscape of DPN can be unified through a tripartite pathogenic model encompassing progressive stages of metabolic dysregulation, chronic inflammation, and overt neuronal damage. Within this framework, six clinical subtypes were identified, namely, hyperglycemia‐driven, dyslipidemia‐driven, inflammation‐driven, dysvascularity‐driven ...
