To provide an insight into the mechanism of interspecific interactions mediated by allelochemicals, cucumber and figleaf gourd seedlings were compared on their response to cinnamic acid, an autotoxin from root exudates of cucumber. Reactive oxygen species metabolism and plasma membrane H(+)-ATPase activity were examined in roots upon exposure to cinnamic(More)
When one of them was inhibited, the two pathways could compensate with each other to guarantee normal growth. Moreover, the sterol biosynthesis inhibitor miconazole could enhance ginsenoside level. Ginsenosides, a kind of triterpenoid saponins derived from isopentenyl pyrophosphate (IPP), represent the main pharmacologically active constituents of ginseng.(More)
MCP-1-induced protein 1 (MCPIP1) plays an important role in the downregulation of the LPS-induced immune response by acting as an RNase targeting IL-6 and IL-12b mRNAs. A conserved domain located in the N-terminal part of MCPIP1 is thought to be responsible for its RNase activity, but its catalytic mechanism is not well understood due to the lack of an(More)
It remains largely mysterious how the genomes of non-enveloped eukaryotic viruses are transferred across a membrane into the host cell. Picornaviruses are simple models for such viruses, and initiate this uncoating process through particle expansion, which reveals channels through which internal capsid proteins and the viral genome presumably exit the(More)
Hepatitis A virus (HAV) remains enigmatic, despite 1.4 million cases worldwide annually. It differs radically from other picornaviruses, existing in an enveloped form and being unusually stable, both genetically and physically, but has proved difficult to study. Here we report high-resolution X-ray structures for the mature virus and the empty particle. The(More)
Asian ginseng (Panax ginseng) and American ginseng (Panax quinquefolium), are thought to be representative plant of Panax species, have important commercial value and are used in worldwide. Panax species produces triterpene saponins called ginsenosides, which are classified into two groups by the skeleton of aglycones, namely dammarane-type and(More)
Ebolavirus can cause hemorrhagic fever in humans with a mortality rate of 50%–90%. Currently, no approved vaccines and antiviral therapies are available. Human TIM1 is considered as an attachment factor for EBOV, enhancing viral infection through interaction with PS located on the viral envelope. However, reasons underlying the preferable usage of hTIM-1,(More)
To detect the content of 12 heavy metals in blood and hair sample from a general population of Pearl River Delta area, and to analyze the influence of duration of residence, gender, age, smoking and drinking on the heavy metal content. Use inductively coupled plasma mass spectrometry to detect the content of 12 heavy metals lead (Pb), mercury (Hg), cadmium(More)
Coxsackievirus A16 belongs to the family Picornaviridae, and is a major agent of hand-foot-and-mouth disease that infects mostly children, and to date no vaccines or antiviral therapies are available. 2A protease of enterovirus is a nonstructural protein and possesses both self-cleavage activity and the ability to cleave the eukaryotic translation(More)
The aim is to explore the molecular regulation mechanism of the pathogenesis of the esophageal squamous cell carcinoma. The expression data of esophageal squamous cell carcinoma were obtained from the GEO database. The differential expression genes were identified by the BRB-array tools and the pathway was analyzed by DAVID online tools. The class(More)
