Unusual Cytology Features of A DICER1‐Mutated Thyroid Nodule: Raising Awareness of A Potential Diagnostic Pitfall During Fine Needle Aspiration

Cytopathology, EarlyView.
This article describes the unusual cytology features of a DICER1‐mutated thyroid nodule. Fine needle aspiration revealed predominantly cell debris/degenerated cells and rare viable follicular cells with mild cytologic atypia. Surgical resection revealed a nodule with nearly complete infarction, which is one specific feature of DICER1‐mutated thyroid ...

Beyond PD‐1: Mechanisms of Resistance to Checkpoint Blockade in Classical Hodgkin Lymphoma and Next‐Generation Immune Strategies

European Journal of Haematology, EarlyView.
ABSTRACT PD‐1 inhibitors have reshaped the treatment landscape of classical Hodgkin lymphoma, yet a substantial proportion of patients exhibit primary or acquired resistance driven by tumor‐intrinsic alterations, immunosuppressive microenvironmental signals, metabolic constraints, and EBV‐mediated modulation.

Poly (I:C) increases the expression of galectin 1, 3, 9 and HGF genes in exosomes isolated from human Wharton's jelly mesenchymal stem cells

Heliyon
Background: Mesenchymal stem cells (MSCs) are commonly employed as a powerful tool for the treatment of immune-mediated problems owing to their capacity to regulate the immune system and differentiate into different tissues.

TGFβ enhances platelet–breast‐cancer‐cell interaction and promotes platelet aggregation

The FEBS Journal, EarlyView.
TGFβ stimulation promotes EMT in MCF7 cells, increasing their ability to bind, activate, and aggregate PLT. This effect involves the upregulation of adhesion molecules Integrin‐αv and Galectin‐3. Inhibiting Integrin‐αv or Galectin‐3, through Cilengitide and GB1103, reduces PLT adhesion to MCF7 and PLT aggregation, suggesting a mechanism linking TGFβ ...

Transglutaminase‐mediated cytokeratin modifications implicated in bile‐acid‐induced hepatocyte death

The FEBS Journal, EarlyView.
Cholestasis and bile‐acid exposure enhance expression and activity of protein crosslinking enzymes TG1 and TG2 in hepatocytes. Substrate proteins were identified by mass spectrometry using biotin‐labeled peptides (pepK5/pepT26) or amine donor (biotinylated pentylamine; BPA). Crosslinking‐induced aggregation and fragmentation of keratin 18 and 8 (K18/K8)

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.

Ampk regulates IgD expression but not energy stress with B cell activation. [PDF]

, 2019
Ampk is an energy gatekeeper that responds to decreases in ATP by inhibiting energy-consuming anabolic processes and promoting energy-generating catabolic processes.

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

Linderalactone mitigates diabetic renal injury by inhibiting macrophage inflammation via the Dectin1/Syk/CARD9/IRF5/NF‐κB pathway

Journal of Diabetes Investigation, EarlyView.
ABSTRACT Background Inflammation plays an essential role in the pathogenesis of diabetic nephropathy (DN). Linderalactone (LNL), as a natural sesquiterpene lactone, has been discovered to have anti‐inflammatory activation. However, the effects of linderalactone on diabetes‐associated renal damage remain unclear.
