Brown NA, Wiger R.
PMID: 20732099

This study compares the responses of rat and chick limb bud micromass cultures to chemical treatment. Eight chemicals, of diverse structure, potency and mechanism, were tested, using two endpoints: extractable alcian blue stain as a measure of differentiation to...

Induction of large cerebral aneurysms by intraperitoneal administration of β-aminopropionitrile fumarate in male rats.

Journal of neurosurgical sciences

Shimoda Y, Nakayama N, Moriwaki T, Abumiya T, Kawabori M, Kurisu K, Gekka M, Hokari M, Ito Y, Houkin K.
PMID: 32031355
J Neurosurg Sci. 2020 Feb 04; doi: 10.23736/S0390-5616.19.04819-7. Epub 2020 Feb 04.

BACKGROUND: It is necessary and useful to obtain an experimental model which steadily and rapidly induces aneurysms for investigation of the pathogenesis of cerebral aneurysm. We attempted to examine whether intraperitoneal administration of β-aminopropionitrile fumarate (BAPN-F) with additional treatments...

Lysyl-Oxidase Dependent Extracellular Matrix Stiffness in Hodgkin Lymphomas: Mechanical and Topographical Evidence.

Cancers

Alfano M, Locatelli I, D'Arrigo C, Mora M, Vozzi G, De Acutis A, Pece R, Tavella S, Costa D, Poggi A, Zocchi MR.
PMID: 35008423
Cancers (Basel). 2022 Jan 05;14(1). doi: 10.3390/cancers14010259.

PURPOSE: The biochemical composition and architecture of the extracellular matrix (ECM) is known to condition development and invasiveness of neoplasms. To clarify this point, we analyzed ECM stiffness, collagen cross-linking and anisotropy in lymph nodes (LN) of Hodgkin lymphomas...

Sildenafil (Viagra) Aggravates the Development of Experimental Abdominal Aortic Aneurysm.

Journal of the American Heart Association

Zhang C, Mohan A, Shi H, Yan C.
PMID: 34984916
J Am Heart Assoc. 2022 Jan 05;e023053. doi: 10.1161/JAHA.121.023053. Epub 2022 Jan 05.

Background cGMP-hydrolyzing phosphodiesterase type 5 (PDE5) regulates vascular smooth muscle cell (SMC) contraction by antagonizing cGMP-dependent protein kinase I (PKGI)-dependent SMC relaxation. SMC contractile dysfunction is implicated in the pathogenesis of aortic aneurysm. PDE5 inhibitors have been used for...

Neuraminidase 1 Exacerbating Aortic Dissection by Governing a Pro-Inflammatory Program in Macrophages.

Frontiers in cardiovascular medicine

Wang Q, Chen Z, Peng X, Zheng Z, Le A, Guo J, Ma L, Shi H, Yao K, Zhang S, Zheng Z, Zhu J.
PMID: 34869700
Front Cardiovasc Med. 2021 Nov 18;8:788645. doi: 10.3389/fcvm.2021.788645. eCollection 2021.

Inflammation plays an important role in aortic dissection (AD). Macrophages are critically involved in the inflammation after aortic injury. Neuraminidases (NEUs) are a family of enzymes that catalyze the cleavage of terminal sialic acids from glycoproteins or glycolipids, which...

BAPN-induced rodent model of aortic dissecting aneurysm and related complications.

Journal of thoracic disease

Chen T, Jiang N, Zhang S, Chen Q, Guo Z.
PMID: 34277056
J Thorac Dis. 2021 Jun;13(6):3643-3651. doi: 10.21037/jtd-21-605.

BACKGROUND: The aim of this study was to investigate the effects of beta-aminopropionitrile (BAPN) on the arterial walls of rodents, and to analyze the gross or pathological changes of arterial and other tissues of rodents treated with BAPN at...

Curr Med Sci. 2021 Oct;41(5):901-908. doi: 10.1007/s11596-021-2425-z. Epub 2021 Oct 13.

OBJECTIVE: Abdominal aortic aneurysm (AAA) is a significant medical problem with a high mortality rate. Nevertheless, the underlying mechanism for the progression and regression of AAA is unknown.METHODS: Experimental model of AAA was first created by porcine pancreatic elastase...

LOXL2 Inhibitors and Breast Cancer Progression.

Antioxidants (Basel, Switzerland)

Ferreira S, Saraiva N, Rijo P, Fernandes AS.
PMID: 33669630

LOX (lysyl oxidase) and lysyl oxidase like-1-4 (LOXL 1-4) are amine oxidases, which catalyze cross-linking reactions of elastin and collagen in the connective tissue. These amine oxidases also allow the cross-link of collagen and elastin in the extracellular matrix...
