The Modified Recombinant Proinsulin: A Simple and Efficient Way to Produce Insulin Glargine in E. coli

open access: yesResearch in Molecular Medicine, 2021
Background: Recombinant insulin glargine, a long-acting analog of insulin, is expressed as proinsulin in the host cell and, after purification and refolding steps, is processed to mature insulin by using trypsin and carboxypeptidase B. Because of several

Thrombin induces tumor growth, metastasis, and angiogenesis: Evidence for a thrombin-regulated dormant tumor phenotype.

open access: yesCancer Cell, 2006
The association of idiopathic venous thrombosis with occult cancer is generally recognized. However, it has not been fully appreciated that thrombin generated during thrombosis can augment the malignant phenotype.

De Novo Designed Minibinders Targeting the GDF15–GFRAL Axis Reverse Cancer Cachexia and Restore Anti‐Tumor Immunity

open access: yesAdvanced Science, EarlyView.
Tumor‐derived GDF15 drives cancer cachexia and suppresses antitumor immunity. Here, de novo designed minibinders targeting the GDF15–GFRAL interface achieve picomolar affinity and potent pathway blockade. The minibinders alleviate cachexia, restore CD8+ T‐cell infiltration, enhance anti–PD‐1 responsiveness, and provide survival benefits across tumor ...

Chemoenzymatic Synthesis of Heparan Sulfate Oligosaccharides by a Covalent Catch‐and‐Release Approach

open access: yesAngewandte Chemie, EarlyView.
A glycan having a hydrazide tag enables chemoenzymatic synthesis of HS oligosaccharides. The hydrazide can, under mild acidic conditions, react with an aldehyde‐containing resin to give an immobilized hydrazone that is stable under neutral conditions, allowing washing. The product can be released by transiminolysis using aqueous hydroxylamine to give a

Comparative Investigation of Thromboelastometry and Thrombin Generation for Patients Receiving Direct Oral Anticoagulants or Vitamin K Antagonists

open access: yesDiagnostics
Background. Alterations induced by direct oral anticoagulants (DOACs) or vitamin K antagonists (VKAs) to thromboelastometry and thrombin generation are not well defined.

Quality Thresholds for Angiogenesis Under Acoustic Manipulation in Engineered Vascular Tissues

open access: yesAdvanced Science, EarlyView.
Defined biological and physical quality thresholds achieved through acoustic manipulation regulate cellular alignment and spatial organization, promoting self‐assembling vasculature, extracellular matrix deposition, and angiogenic responses, thereby establishing critical acoustic patterning requirements for engineered vascular tissue development in ...

Direct Regioselective para‐Fluorination via I(I)/I(III) Catalysis

open access: yesAngewandte Chemie, EarlyView.
A direct, para‐selective fluorination by I(I)/I(III) catalysis is disclosed that does not require substrate pre‐functionalization. This strategy leverages the Leonard link inherent to phenylpropanoate and phenylpropanamides to promote a spirocyclization/para‐selective sequence. The C3‐side chain maps onto a range of common drug scaffolds and allows the

Endothelial protease-activated receptor 4: impotent or important?

open access: yesFrontiers in Cardiovascular Medicine
The protease thrombin, which increases its levels with various pathologies, can signal through the G protein-coupled receptors protease-activated receptors 1 and 4 (PAR1/PAR4). PAR1 is a high-affinity receptor for thrombin, whereas PAR4 is a low-affinity

The Transition of Prothrombin to Thrombin

open access: yesJournal of Thrombosis and Haemostasis, 2013
The proteolytic conversion of prothrombin to thrombin catalyzed by prothrombinase is one of the more extensively studied reactions of blood coagulation.

Bioinspired Passive Flow Routing to Mitigate Thrombosis in Prosthetic Heart Valves and Cardiovascular Devices

open access: yesAdvanced Science, EarlyView.
Bioinspired passive flow routing mitigates thrombosis in cardiovascular devices by redirecting a small fraction of forward flow into stagnation‐prone regions. Inspired by avian alula and aircraft slat mechanisms, strategically placed routing channels restore washout around mechanical heart valves, reducing low‐shear exposure by four orders of magnitude
