Numerical study of cancer cell invasion dynamics using adaptive mesh refinement: the urokinase model [PDF]

arXiv, 2014
In the present work we investigate the chemotactically and proteolytically driven tissue invasion by cancer cells. The model employed is a system of advection-reaction-diffusion equations that features the role of the serine protease urokinase-type plasminogen activator.

From Invaginating Site to Deep Lesion: Spatial Transcriptomics Unravels Ectopic Endometrial Penetration Features in Adenomyosis

Advanced Science, EarlyView.
This work utilizes spatial transcriptomics to map the transcriptional landscape of adenomyosis with obvious invagination structure from the invaginating site to deep lesions. By integrating with single‐cell RNA sequencing, this study elucidates the molecular features of invagination, invasion, and fibrosis, and finds the major participants and vital ...

Studies on a novel serine protease of a ΔhapAΔprtV Vibrio cholerae O1 strain and its role in hemorrhagic response in the rabbit ileal loop model.

PLoS ONE, 2010
Two well-characterized proteases secreted by Vibrio cholerae O1 strains are hemagglutinin protease (HAP) and V. cholerae protease (PrtV). The hapA and prtV knock out mutant, V. cholerae O1 strain CHA6.8ΔprtV, still retains residual protease activity.

Structures of a bi-functional Kunitz-type STI family inhibitor of serine and aspartic proteases: could the aspartic protease inhibition have evolved from a canonical serine protease-binding loop? [PDF]

, 2016
Bi-functional inhibitors from the Kunitz-type soybean trypsin inhibitor (STI) family are glycosylated proteins able to inhibit serine and aspartic proteases.

Conditional Overexpression of Serpine2 Promotes Hair Cell Regeneration from Lgr5+ Progenitors in the Neonatal Mouse Cochlea

Advanced Science, EarlyView.
This study indicates that Serpine2 plays a pivotal role in hair cell (HC) regeneration from Lgr5+ progenitors in the neonatal mouse cochlea. Conditional overexpression of Serpine2 in cochlear Lgr5+ progenitors results in a significantly increased number of ectopic HCs, particularly ectopic inner HCs, and these HCs are likely derived from Lgr5 ...

BC‐11 is a covalent TMPRSS2 fragment inhibitor that impedes SARS‐CoV‐2 host cell entry

Archiv der Pharmazie, Volume 356, Issue 1, January 2023., 2023
Drug repurposing has the potential to accelerate the discovery of TMPRSS2 inhibitors acting as COVID‐19 antivirals. In this regard, a low throughput screening led to the identification of BC‐11 as a covalent TMPRSS2 fragment inhibitor (IC50 = 1.44 µM), displaying significant SARS‐CoV‐2 entry inhibition (EC50 = 66 µM). Abstract Host cell entry of severe

Site-directed mutagenesis of the proposed catalytic amino acids of the Sindbis virus capsid protein autoprotease [PDF]

, 1990
The structural proteins of Sindbis virus are translated as a polyprotein precursor that is cleaved upon translation. The capsid protein is postulated to be a serine protease that releases itself from the N terminus of the nascent polyprotein by ...

DNA‐PKcs‐Driven YAP1 Phosphorylation and Nuclear Translocation: a Key Regulator of Ferroptosis in Hyperglycemia‐Induced Cardiac Dysfunction in Type 1 Diabetes

Advanced Science, EarlyView.
In the context of chronic hyperglycemia, a DDR is initiated, leading to the pathological activation of DNA‐PKcs in the diabetic heart. This activated DNA‐PKcs directly interacts with and phosphorylates YAP1 at Thr226, thereby increasing the nuclear expression of YAP1.
