Trichothecenes NIV and DON modulate the maturation of murinedendritic cells [PDF]

, 2010
Nivalenol (NIV) and Deoxynivalenol (DON), mycotoxins of the trichothecene family are considered very common food contaminants. In this work, we investigated whether the immunotoxic effects ascribed to these trichothecenes may be mediated by perturbations

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.

Inhibition of jasmonic acid‐isoleucine conjugating enzyme JAR1 shifts the local and systemic leaf signals and metabolic profiles in Arabidopsis

New Phytologist, EarlyView.
Summary Jasmonates (JAs)‐mediated pathways are central signaling hubs in plant defense responses. However, the identification of mobile and nonmobile signals involved in downstream systemic signaling is still less studied. Here, we investigate the role of the jasmonic acid‐isoleucine (JA‐Ile) conjugating enzyme, JAR1, in shifting wound‐induced local ...

The mitochondrial‐targeted antioxidant SkQ1 prevents skeletal muscle mitochondrial‐apoptotic but not necroptotic signalling during ovarian cancer

The Journal of Physiology, EarlyView.
Abstract figure legend An evaluation of the degree to which mitochondrial hydrogen peroxide emission (mH2O2)‐mediated apoptotic and necroptotic signalling contributes to skeletal muscle atrophy in an orthotopic epithelial ovarian cancer (EOC) model. To determine whether attenuating mH2O2 could prevent regulated cell death signalling and mitigate muscle
