Numerous epidemiological studies have associated exposure to ambient particulate matter (PM) with pulmonary and cardiovascular health effects. Macrophages as a part of the primary pulmonary defence system play a crucial role by generating p...
Air pollution-associated fly ash particles induce fibrotic mechanisms in primary fibroblasts [0.03%]

Air pollution is associated with a variety of respiratory and cardiovascular disorders, including fibrosis. To understand the possible molecular mechanisms underlying this observation, we examined the effect of particulate matter on primary...
Regulatory effects of the mitochondrial energetic status on mitochondrial p66Shc [0.03%]
线粒体能量状态对线粒体p66Shc的调节作用

Francesca Orsini et al.
p66(Shc) promotes apoptosis and controls the intracellular redox balance. A fraction of p66(Shc) exists within mitochondria, where it oxidizes cytochrome c to form hydrogen peroxide, which in turn induces mitochondrial permeability and apop...
Singlet oxygen inactivates protein tyrosine phosphatase-1B by oxidation of the active site cysteine [0.03%]
单线态氧通过氧化活性位点半胱氨酸使蛋白质酪氨酸磷酸酶-1B失活
