Maternal and infant gut microbiome

iMeta, EarlyView.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

Organ‐Specific Human Microbiomes and Dysbiosis: Mechanistic Links to Disease and Emerging Therapeutic Strategies

Journal of Clinical Laboratory Analysis, EarlyView.
Schematic overview of the human microbiome and major microbiota‐derived metabolites across body sites, highlighting the gut–brain, gut–heart, and gut–kidney axes in host physiology and disease. ABSTRACT Background The human microbiome is a dynamic and diverse community of microorganisms that affects susceptibility to illness and promotes wellness ...

Navigating the Complexity: A Comprehensive Review of GSK‐3 Inhibition in Regenerative Medicine

Medicinal Research Reviews, EarlyView.
ABSTRACT Glycogen synthase kinase‐3 (GSK‐3) is a central regulator of numerous cellular signaling pathways, with critical roles in metabolism, proliferation, differentiation, and tissue regeneration. This review explores the multifaceted effects of pharmacological GSK‐3 inhibition across multiple body districts, focusing on its highly context‐dependent

Foldamer-mediated manipulation of a pre-amyloid toxin

Nature Communications, 2016
Intrinsically disordered proteins that form amyloid fibrils are hard to target with traditional therapeutic approaches. Here, the authors report on an oligoquinoline derivative that binds the human islet amyloid polypeptide, stabilising an alpha-helical ...

Impact of Stabilizing Osmolytes on the Conformational Dynamics of Human and Rat Islet Amyloid Polypeptides

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The aggregation of human islet amyloid polypeptide (hIAPP) into cytotoxic oligomers and amyloid fibrils is a hallmark of type 2 diabetes mellitus (T2DM), leading to pancreatic β‐cell dysfunction. In contrast, rat IAPP (rIAPP) is largely non‐amyloidogenic. Osmolytes such as glucose, glycerol, and sorbitol are known to stabilize globular protein

Membrane permeabilization by Islet Amyloid Polypeptide [PDF]

Chemistry and Physics of Lipids, 2009
Membrane permeabilization by Islet Amyloid Polypeptide (IAPP) is suggested to be the main mechanism for IAPP-induced cytotoxicity and death of insulin-producing beta-cells in type 2 diabetes mellitus (T2DM). The insoluble fibrillar IAPP deposits (amyloid) present in the pancreas of most T2DM patients are not the primary suspects responsible for ...

The triphenylmethane dye brilliant blue G is only moderately effective at inhibiting amyloid formation by human amylin or at disaggregating amylin amyloid fibrils, but interferes with amyloid assays; Implications for inhibitor design.

PLoS ONE, 2019
The development of inhibitors of islet amyloid formation is important as pancreatic amyloid deposition contributes to type-2 diabetes and islet transplant failure.

Molecular Mechanisms of Amylin Turnover, Misfolding and Toxicity in the Pancreas

Molecules, 2022
Amyloidosis is a common pathological event in which proteins self-assemble into misfolded soluble and insoluble molecular forms, oligomers and fibrils that are often toxic to cells.

Identification and Discrimination of Sulfated and Unsulfated Gut‐Hormone Biomarkers in Human Serum by Nanopore

Small, EarlyView.
This study discriminates between sulfated and unsulfated cholecystokinin‐8 gut‐hormone forms at single‐molecule‐level resolution. Using an aerolysin nanopore embedded in a hybrid lipid‐polymer membrane, the system produces distinct electrical signatures enabling highly sensitive detection, even in 20% human serum.

Role of Aromatic Interactions in Amyloid Formation by Islet Amyloid Polypeptide [PDF]

Biochemistry, 2012
Aromatic-aromatic and aromatic-hydrophobic interactions have been proposed to play a role in amyloid formation by a range of polypeptides, including islet amyloid polypeptide (IAPP or amylin). IAPP is responsible for amyloid formation in patients with type 2 diabetes. The polypeptide is 37 residues long and contains three aromatic residues, Phe-15, Phe-
