Oxidative Stress Drives Cell Cycle Stalling, Apoptosis and Metabolic Suppression in Cystatin B Deficient EPM1 Patient iPSCs

Cell Proliferation, EarlyView.
CSTB deficient EPM1 iPS cells manifest increased lysosomal activity and oxidative stress, which lead to DNA damage, cell cycle defects and increased apoptosis. As a protective response, metabolism is suppressed. Image created by BioRender https://BioRender.com/t44oc6h.

Multi‐Parametric Magnetic Resonance Imaging to Assess Empagliflozin Effect on the Kidneys in People With Type 2 Diabetes Mellitus: A Pilot Clinical Trial

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Empagliflozin is renoprotective in Type 2 diabetes mellitus (T2DM). Our primary aim was to assess empagliflozin's effect on glomerular filtration rate and renal vascular resistance using multiparametric MRI (MpMRI). Our secondary aim was to assess the impact of empagliflozin on additional MpMRI‐derived metrics including markers of tissue ...

A five-residue motif for the design of domain swapping in proteins

Nature Communications, 2019
Designing interfaces that can induce protein-protein interactions is a challenging problem. Here the authors show that a five amino acid sequence known to mediate domain swapping in cystatins can drive oligomerization when grafted onto functionally and ...

The origin and evolution of plant cystatins and their target cysteine proteinases indicate a complex functional relationship

BMC Evolutionary Biology, 2008
Background Cystatins and their putative targets, the families of cysteine proteinases C1A and C13 play key roles in plants. Comparative genomic analyses are powerful tools to obtain valuable insights into the conservation and evolution of the proteinases

Hepatic Safety of Orforglipron in Adults With Obesity or Overweight and/or Type 2 Diabetes: A Pooled Analysis of the Orforglipron Phase 3 Clinical Trials

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Orforglipron is a novel small‐molecule, once daily oral non‐peptide GLP‐1 receptor agonist. The hepatic safety profile in adults with obesity or overweight and/or type 2 diabetes (T2D) across seven orforglipron Phase 3 clinical trials was assessed.

Leishmania infantum: Antiproliferative effect of recombinant plant cystatins on promastigotes and intracellular amastigotes estimated by direct counting and real-time PCR

, 2009
Two recombinant barley cystatins, HvCPI5 and HvCPI6, have been tested in vitro against promastigotes and intracellular amastigotes of Leishmania infantum in the J774 monocytic cell line. Toxicity of cystatins for J774 cells was also determined.

Ectromelia virus suppresses expression of cathepsins and cystatins in conventional dendritic cells to efficiently execute the replication process

BMC Microbiology, 2019
Background Cathepsins are a group of endosomal proteases present in many cells including dendritic cells (DCs). The activity of cathepsins is regulated by their endogenous inhibitors – cystatins.

Extracellular matrix and proteolysis: mechanisms driving irreversible changes and shaping cell behavior

The FEBS Journal, EarlyView.
Irreversible ECM proteolysis by remodeling enzymes shapes development, homeostasis, and disease. ECM‐degrading proteases display cell specificity and are governed by shared mechanisms, exhibiting functional redundancy in generating matrikines, growth factors, and cytokines.

Cloning and characterisation of novel cystatins from elapid snake venom glands

, 2011
Snake venoms contain a complex mixture of polypeptides that modulate prey homeostatic mechanisms through highly specific and targeted interactions. In this study we have identified and characterised cystatin-like cysteine-protease inhibitors from elapid ...

A guide to the types, structures, and multifaceted functions of matrix metalloproteinases in cancer

The FEBS Journal, EarlyView.
Matrix metalloproteinases (MMPs) orchestrate cancer progression and metastasis through proteolytic and non‐proteolytic actions. By remodeling the tumor microenvironment, enhancing growth factor availability, and modulating cell behavior, MMPs promote proliferation, migration or invasion, and epithelial‐to‐mesenchymal transition. Alongside extracellular
