Adhesion of Immunoglobulins to Band3 Promotes Increased Erythrocyte Sedimentation Rate in Multiple Myeloma

Cell Proliferation, EarlyView.
Decreased sialic acid increases the adhesion of RBC membranes to immunoglobulins leading to an increased erythrocyte sedimentation rate (ESR). The increase in reactive oxygen species (ROS) damages the sialic acid glycosyl chains on the surface of RBC membrane proteins, causing the membrane proteins to be overexposed to the plasma environment due to the

Biostimulants in plant brassinosteroid hormone receptor BRI1 activation—a new system to evaluate activation capacity

The FEBS Journal, EarlyView.
A novel assay evaluates plant biostimulants targeting the brassinosteroid receptor BRI1, a central component in plant growth and development. By expressing BRI1 in fission yeast, functional activation by brassinolide (BL) was enabled. Transcriptomic profiling identified BL‐responsive genes, leading to a GFP‐based reporter system. This platform offers a

CLEC18A interacts with sulfated glycosaminoglycans and controls clear cell renal cell carcinoma progression

The FEBS Journal, EarlyView.
CLEC18A is a previously poorly characterized C‐type lectin. We mapped the expression of CLEC18A to the proximal tubule of the kidney and found CLEC18A to interact with sulfated glycosaminoglycans on proteoglycans. Furthermore, we found that CLEC18A plays an important role in hindering the progression of clear cell renal cell carcinomas in humans and in

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Structural and functional characterization of the newly identified Photorhabdus laumondii tumor necrosis factor‐like lectin

The FEBS Journal, EarlyView.
We characterize the PLTL lectin from Photorhabdus laumondii, which adopts a unique TNF‐like fold. Binding assays reveal a preference for branched histo‐blood group oligosaccharides. Protein crystallography uncovers a novel hexameric assembly and identifies key residues involved in carbohydrate recognition.

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

Behind the scenes: how the EMILIN/Multimerin family shapes the cancer landscape

The FEBS Journal, EarlyView.
The EMILIN/Multimerin family members regulate key hallmarks of cancer—including apoptosis, angiogenesis, metastasis, and tumor microenvironment remodeling. As indicated, their function in immune evasion, drug resistance, and metabolic reprogramming remains largely unexplored.

The fc fragment of IgMs binds C1q to activate the first step of the classical complement pathway, while inhibiting complement‐dependent cytotoxicity

The FEBS Journal, EarlyView.
Multimeric IgM‐fragment crystallizable region (Fc) fragments retain the ability to bind C1q and initiate the classical complement pathway, leading to C4 activation and deposition in vitro. However, the Fc cores can also inhibit complement‐dependent cytotoxicity by competing with surface‐bound antibodies for C1q engagement.

Ligand‐specific tuning of CLEC10A signalling strength and dendritic cell responses through engagement of different GalNAc‐containing glycan structures

The FEBS Journal, EarlyView.
The authors investigated the effects of various glycan ligands for CLEC10A, a lectin receptor expressed on dendritic cells (DCs). Monocyte‐derived DCs were stimulated with glycan‐conjugated dendrimers in combination with the TLR1/2 ligand Pam3CysK4, and responses were investigated at the mRNA and protein level.
