Comparison of Receptor‐Mediated Endocytosis and Its Application to Enhance DNA Transfection by TFAMoplex

Advanced NanoBiomed Research, EarlyView.
We developed an assay to distinguish cellular binding from internalization. Compatible with microscopy and high‐throughput screening, the method identifies ligand‐mediated uptake. Applying top candidates to a protein‐based DNA carrier enhanced transfection efficiency, providing a rational strategy to improve non‐viral gene delivery systems.

C-reactive protein: the nexus between inflammation and protein misfolding diseases

Frontiers in Immunology
C-reactive protein (CRP), an acute-phase protein primarily produced by hepatocytes in response to pro-inflammatory cytokines, is a widely used clinical marker for inflammation and tissue damage. In its native state, CRP exists in a stable pentameric form

Autoimmune Thyroiditis Mitigates the Effect of Metformin on Plasma Prolactin Concentration in Men with Drug-Induced Hyperprolactinemia

Pharmaceuticals
Metformin inhibits the secretory function of overactive anterior pituitary cells, including lactotropes. In women of childbearing age, this effect was absent if they had coexisting autoimmune (Hashimoto) thyroiditis.

A Five-coordinate Metal Center in Co(II)-substituted VanX [PDF]

, 2005
In an effort to structurally probe the metal binding site in VanX, electronic absorption, EPR, and extended x-ray absorption fine structure (EXAFS) spectroscopic studies were conducted on Co(II)-substituted VanX.

Photocaged Oxytocin and Vasopressin Probes to Decipher Neuropeptide Signalling With High Spatiotemporal Resolution

Angewandte Chemie International Edition, EarlyView.
Novel and biocompatible photoactivatable oxytocin and vasopressin probes, utilising state‐of‐the‐art photocages, remain inactive in the dark. Light exposure facilitates rapid spatiotemporal receptor activation and phospholipase C (PLC)‐mediated downstream signalling. Figure created in https://BioRender.com.

Polyfluoroalkyl‐Tagged Cell‐Penetrating Peptide‐Additives Enhance Intracellular Protein Delivery via Sustained Monomeric Lipid Interaction

Angewandte Chemie International Edition, EarlyView.
We introduce cell‐penetrating peptides (CPPs) with polyfluoroalkyl‐tags that drastically enhance intracellular protein delivery by promoting membrane retention. Via the combination of live‐cell imaging, biophysical analysis, and computational simulations, we reveal how fluorous CPPs interact with membranes via monomeric interactions and dynamic tag ...

Time‐Resolved Native Mass Spectrometry Reveals Reversible Light‐Driven Oligomerization of Arabidopsis Cryptochrome 1 and Its Antagonism by BIC1

Angewandte Chemie International Edition, EarlyView.
Time‐resolved native mass spectrometry uncovers the blue‐light‐dependent kinetic mechanism of Arabidopsis CRY1 oligomerization, proceeding sequentially from monomers to dimers and tetramers. ATP promotes assembly, whereas BIC1 actively blocks and disassembles tetramers independent of light, providing mechanistic insight into the regulation of ...

A conformational change of C-reactive protein drives neutrophil extracellular trap formation in inflammation

BMC Biology
Background C-reactive protein (CRP) represents a routine diagnostic marker of inflammation. Dissociation of native pentameric CRP (pCRP) into the monomeric structure (mCRP) liberates proinflammatory features, presumably contributing to excessive immune ...
