Local renin angiotensin system and sperm DNA fragmentation

Asian Journal of Andrology, 2022
The renin angiotensin system (RAS) appears to influence male fertility at multiple levels. In this work, we analyzed the relationship between the RAS and DNA integrity.

An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

Limnology and Oceanography: Methods, EarlyView.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

The internal sequence of the peptide-substrate determines its N-terminus trimming by ERAP1.

PLoS ONE, 2008
BackgroundEndoplasmic reticulum aminopeptidase 1 (ERAP1) trims N-terminally extended antigenic peptide precursors down to mature antigenic peptides for presentation by major histocompatibility complex (MHC) class I molecules.

Expression of Aminopeptidase N on Human Choriocarcinoma Cells and Cell Growth Suppression by the Inhibition of Aminopeptidase N Activity [PDF]

Japanese Journal of Cancer Research, 1994
We previously found that an aminopeptidase inhibitor, ubenimex (bestatin), had a growth‐suppressive effect on Choriocarcinoma cell lines in vitro. To clarify the mechanism of this action, we investigated the expression of aminopeptidase N (AP‐N/CD13) on Choriocarcinoma cells and other human tumor cells. Two Choriocarcinoma cell lines, NaUCC‐4 and Be Wo,

Migrasomes, Matrix‐Bound Nanovesicles, and More: Messengers in the Matrix

PROTEOMICS, EarlyView.
ABSTRACT Extracellular vesicles (EVs) and particles (EPs) are diverse micro‐ and nanoparticles that circulate in bodily fluids and can attach to, or be deposited onto, the extracellular matrix (ECM) and other surfaces. To date, the nomenclature and classification of matrix‐bound or matrix‐associated EVs and EPs (MEVPs) have been unclear, largely due to

Development of Hydroxamate Derivatives Containing a Pyrazoline Moiety as APN Inhibitors to Overcome Angiogenesis

Molecules, 2022
Aminopeptidase N (APN) was closely associated with cancer invasion, metastasis, and angiogenesis. Therefore, APN inhibitors have attracted more and more attention of scientists as antitumor agents.

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

Phytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.

Phytochemical‐Based Strategies for Lung Cancer: Clinical Insights Into Pleiotropic Molecular Signaling and Therapeutic Roles

Phytotherapy Research, EarlyView.
Lung cancer (LC) remains the leading cause of global cancer‐related death. Phytochemicals from medicinal plants are increasingly being considered as potential LC treatment agents due to their multi‐targeted action, safety, and accessibility. These have anticancer properties by regulating key molecular signaling pathways.

Anti-Inflammatory and Antitumor Effects of Hydroxytyrosol but Not Oleuropein on Experimental Glioma In Vivo. A Putative Role for the Renin-Angiotensin System

Biomedicines, 2018
Functional roles of the angiotensin peptides of the renin-angiotensin system (RAS) cascade can be analyzed through their corresponding proteolytic regulatory enzymes aspartyl aminopeptidase (ASAP), aminopeptidase A (APA), aminopeptidase B (APB ...

Proteases as Therapeutic Targets Against the Parasitic Cnidarian Ceratonova shasta: Characterization of Molecules Key to Parasite Virulence In Salmonid Hosts

Frontiers in Cellular and Infection Microbiology, 2022
Proteases and their inhibitors play critical roles in host-parasite interactions and in the outcomes of infections. Ceratonova shasta is a myxozoan pathogen that causes enteronecrosis in economically important salmonids from the Pacific Northwest of ...
