Expression of a dominant negative fragment of the spectrin family member Syne-1 causes an accumulation of binucleate cells, suggesting a role for this protein in cytokinesis. An association of this fragment with the C-terminal tail domain of the kinesin II subunit KIF3B was identified by yeast two-hybrid and co-precipitation assays, suggesting that the role(More)
Asian swamp eel is a highly commercial fish, primarily for China and other Asian countries. The aim of this paper is to evaluate the genetic diversity of wild and cultured samples of Asian swamp eel Monopterus albus using ISSR markers. A total of 129 individuals belonging to three wild samples, Xiantao (XT), Huanggang (HG), Xinyang (XY) and three cultured(More)
Explaining the determinants involved in regulating the equilibrium between different chromatin structural states is fundamental to understanding differential gene expression. Histone variant H2A.Z is essential to chromatin architecture in higher eukaryotes but its role has not yet been explained. We show here that H2A.Z facilitates the intramolecular(More)
We isolated an activation-tagged Arabidopsis (Arabidopsis thaliana) line, constitutive disease susceptibility2-1D (cds2-1D), that showed enhanced bacterial growth when challenged with various Pseudomonas syringae strains. Systemic acquired resistance and systemic PATHOGENESIS-RELATED GENE1 induction were also compromised in cds2-1D. The T-DNA insertion(More)
Controlling the degree of higher order chromatin folding is a key element in partitioning the metazoan genome into functionally distinct chromosomal domains. However, the mechanism of this fundamental process is poorly understood. Our recent studies suggested that the essential histone variant H2A.Z and the silencing protein HP1alpha may function together(More)
A newly emerged H7N9 virus has caused 132 human infections with 37 deaths in China since 18 February 2013. Control measures in H7N9 virus-positive live poultry markets have reduced the number of infections; however, the character of the virus, including its pandemic potential, remains largely unknown. We systematically analyzed H7N9 viruses isolated from(More)
Although it is believed that the interconversion between permissive and refractory chromatin structures is important in regulating gene transcription, this process is poorly understood. Central to addressing this issue is to elucidate how a nucleosomal array folds into higher-order chromatin structures. Such findings can then provide new insights into how(More)
Many tumor cells rely on aerobic glycolysis instead of oxidative phosphorylation for their continued proliferation and survival. Myc and HIF-1 are believed to promote such a metabolic switch by, in part, upregulating gene expression of pyruvate dehydrogenase (PDH) kinase 1 (PDHK1), which phosphorylates and inactivates mitochondrial PDH and consequently(More)
H9N2 subtype influenza viruses have been detected in different species of wild birds and domestic poultry in many countries for several decades. Because these viruses are of low pathogenicity in poultry, their eradication is not a priority for animal disease control in many countries, which has allowed them to continue to evolve and spread. Here, we(More)
Human immunodeficiency virus (HIV)/AIDS continues to spread worldwide, and most of the HIV-infected people living in developing countries have little or no access to highly active antiretroviral therapy. The development of efficient and low-cost microbicides to prevent sexual transmission of HIV should be given high priority because there is no vaccine(More)
