OBJECTIVE Brain injury induces an acute increase in the expression of gap junction protein connexin43 (Cx43). It also leads to cerebral edema, probably due to the swelling and proliferation of astrocytes reactive to the injury. Antisense oligodeoxynucleotides (AS-ODN) targeting Cx43 were tested for their ability to reduce reactive astrocytosis and cerebral(More)
Neurofibrillary tangles are aggregates of hyperphosphorylated tau that are one of the pathological hallmarks of Alzheimer's disease (AD). Tau phosphorylation is regulated by a balance of kinase and phosphatase activities. Our previous study has demonstrated that ginsenoside Rd, one of the principal active ingredients of Pana notoginseng, inhibits okadaic(More)
Olfactory ensheathing cells (OECs), the major glia cells in the olfactory system, have been extensively studied because of their ability to promote axonal growth and regeneration. Whether it could facilitate synaptogenesis is an important, but remains as yet an unanswered question. We have identified a subgroup of Wnt signaling-activated OECs,(More)
Our previous clinical and basic studies have demonstrated that ginsenoside Rd (GS-Rd) has remarkable neuroprotective effects after cerebral ischemia but the underlying mechanisms are still unknown. In our latest studies, we revealed that GS-Rd could prevent mitochondrial release of apoptosis-inducing factor (AIF) and reduce inflammatory response following(More)
N-myc downstream-regulated gene 2 (Ndrg2) is well-known for its involvement in tumor cell proliferation and differentiation. This promotes us to investigate whether Ndrg2 also functions in neurogenesis, during which some cellular events are similar to that of tumorigenesis. As the first step in exploring the role of Ndrg2 in neurogenesis, here we performed(More)
Lead is a heavy metal and important environmental toxicant and nerve poison that can destruction many functions of the nervous system. Lead poisoning is a medical condition caused by increased levels of lead in the body. Lead interferes with a variety of body processes and is toxic to many organs and issues, including the central nervous system. It(More)
Filamentous actins (F-actins) play a vital role in epidermal cell morphogenesis. However, a limited number of studies have examined actin-dependent leaf epidermal cell morphogenesis events in rice. In this study, two recessive mutants were isolated: less pronounced lobe epidermal cell2-1 (lpl2-1) and lpl3-1, whose leaf and stem epidermis developed a smooth(More)
Stomata are highly specialized epidermal structures that control transpiration and gas exchange between plants and the environment. Signal networks underlying stomatal development have been previously uncovered but much less is known about how signals involved in stomatal development are transmitted to RNA polymerase II (Pol II or RPB), which plays a(More)
