Compelling evidences have shown that diverse environmental insults arising during early life can either directly lead to a reduction in the number of dopaminergic neurons or cause an increased susceptibility to neurons degeneration with subsequent environmental insults or with aging alone. Oxidative stress is considered the main effect of neurotoxins(More)
Methylmercury (MeHg) is a long-lasting organic pollutant primarily found in the aquatic environment. The developing brain is particularly sensitive to MeHg due to reduced proliferation of neural stem cell. Although several mechanisms of MeHg-induced apoptosis have been defined in culture models, it remains unclear whether mitochondrial DNA (mtDNA) mutation(More)
Paraquat (PQ), one of the most widely used fast-acting and non-selective herbicides in the world is believed to act as a neurotoxicant, which increases the risk of developing Parkinson's disease (PD) by selectively impairing dopaminergic neurons. However, the mechanism of PQ on neural progenitor cells remains unclear. As regulator of mRNA expression, miRNA(More)
Organizational ambidexterity, defined as the simultaneously pursuit of both exploitation and exploration activities, is essential for organizations’ survival, thrive and mature. However, the building of this capability is still ambiguous in prior literatures. This paper draws on the organizational learning theories, presents how two types of learning (i.e.(More)
OBJECTIVE To investigate the role of Wnt signaling pathway on paraquat (PQ)induced PC12 cells damage. METHODS Using PC12 cells, in this study CCK8 assay was used to detect the effect of cell viability. The cell apoptosis and cell cycle was detected by flow cytometry. The real-time polymerase chain reaction (RT-PCR) was used to measure the mRNA expression(More)
Mitochondria are essential organelles and important targets for environmental pollutants. The detection of mitochondrial biogenesis and generation of reactive oxygen species (ROS) and p53 levels following low-dose methylmercury (MeHg) exposure could expand our understanding of underlying mechanisms. Here, the sensitivity of immortalized human neural(More)
