There is increasing evidence that non-enzymatic post-translational protein modifications might play key roles in various diseases. These protein modifications can be caused by free radicals generated during oxidative stress or by their products generated during lipid peroxidation. 4-Hydroxynonenal (HNE), a major biomarker of oxidative stress and lipid(More)
Protein adhesion and cell response to plasma-treated polymer surfaces were studied. The polymer polyethylene terephthalate (PET) was treated in either an oxygen plasma to make the surface hydrophilic, or a tetrafluoromethane CF(4) plasma to make the surface hydrophobic. The plasma source was radiofrequency (RF) discharge. The adsorption of albumin and other(More)
The reactive aldehyde, 4-hydroxynonenal (HNE), is recognized as a product of lipid peroxidation, which binds to macromolecules, in particular proteins. HNE-modified proteins (HNE-MP) have been shown to accumulate during ageing, generally by using polyclonal antibodies, which increase the possibility of detecting false positives. Therefore, we have used a(More)
INTRODUCTION The aim of this study was to assess the expression and production of inflammation mediators in basal condition and after angiotensin II (AngII) in otosclerosis. MATERIALS AND METHODS Human stapedial cell cultures (6 otosclerosis and 6 controls) were incubated with AngII (10(-7)M, 24 h) or vehicle. Cytokines and their mRNA expression were(More)
Conventional anticancer therapies such as radiotherapy and chemotherapies are associated with oxidative stress generating reactive oxygen species (ROS) and reactive aldehydes like 4-hydroxynonenal in cancer cells that govern them to die. The main mechanism activated due to exposure of the cell to these reactive species is the Nrf2-Keap1 pathway. Although(More)
