Cleavage of the urokinase receptor (uPAR) on oral cancer cells: regulation by transforming growth factor – β1 (TGF-β1) and potential effects on migration and invasion

BMC Cancer, 2017
Background Urokinase plasminogen activator (uPA) receptor (uPAR) is up-regulated at the invasive tumour front of human oral squamous cell carcinoma (OSCC), indicating a role for uPAR in tumour progression.

Activation of the Urokinase Plasminogen Activator/Urokinase Plasminogen Activator Receptor System in Periodontitis: A Case–Control Study

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Introduction The plasminogen activating (PA) system has a multitude of functions such as wound healing, proteolytic activity, collagen degradation and cell growth, and the role of the urokinase plasminogen activator/urokinase plasminogen activator receptor (uPA/uPAR) system has been studied in many disease states.

Periodontitis and Diabetes: Mechanistic Evidence of a Circular Relationship

Journal of Periodontal Research, EarlyView.
This narrative review aimed to explore the underlying mechanisms that connect periodontitis to diabetes (and vice versa) and that influence disease susceptibility, progression and response to treatment. ABSTRACT The circular relationship between periodontitis and diabetes mellitus is one of the most established oral‐systemic links.

How I Investigate Bleeding Disorders of Unknown Cause: Current Diagnostic Pathways and Gaps in Laboratory Investigation

International Journal of Laboratory Hematology, Volume 48, Issue 6, Page 1289-1297, December 2026.
ABSTRACT Bleeding disorder of unknown cause (BDUC) constitutes the largest group of patients presenting with a mild‐to‐moderate bleeding tendency in tertiary care settings. Their clinical bleeding phenotype is characterized by mucocutaneous bleeding, as well as bleeding following surgical challenges or childbirth, and is associated with impaired health‐

Inhibition of receptor-dependent urokinase signaling by specific Ser to Glu substitutionss

, 2002
We have previously reported that phosphorylation of human urokinase on Ser138/303 abolishes its catalyticindependent motogen and proadhesive abilities, whereas receptor binding is not affected.

Hemostatic balance on the surface of leukemic cells: the role of tissue factor and urokinase plasminogen activator receptor

Haematologica, 2005
BACKGROUND AND OBJECTIVES: The frequency of thrombotic complications is increased in patients with acute leukemia. Since coagulation processes take place on cell membranes, we hypothesized that expression of coagulation proteins on blast membrane could ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, Volume 20, Issue 11, Page 2955-2973, November 2026.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Created Ex Nihilo: A Near‐Infrared Afterglow Luminescent Framework of Imidazole Derivatives for Bioimaging

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
A series of Ir(III) complexes (Ir‐1‐Ir‐4) based on imidazole derivatives provide a new afterglow luminescence mechanism. The work expands the range of afterglow luminescence frameworks to overcome: (i) a lack of new afterglow scaffolds; (ii) the dependence on initial external light activation; and (iii) aggregation‐caused quenching.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, Volume 20, Issue 11, Page 2569-2583, November 2026.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

E4 engages uPAR and enolase-1 and activates urokinase to exert antifibrotic effects

JCI Insight, 2021
Fibroproliferative disorders such as systemic sclerosis (SSc) have no effective therapies and result in significant morbidity and mortality. We recently demonstrated that the C-terminal domain of endostatin, known as E4, prevented and reversed both ...
