Insulin-stimulated GLUT4 translocation is central to glucose homeostasis. Functional assays to distinguish individual steps in the GLUT4 translocation process are lacking, thus limiting progress toward elucidation of the underlying molecular mechanism. Here we have developed a robust method, which relies on dynamic tracking of single GLUT4 storage vesicles(More)
[1] In this paper, we analyzed interannual variations of normalized difference vegetation index (NDVI) and their relationships with climatic variables (temperature and precipitation) and human activity in China between 1982 and 1999. Monthly and seasonal NDVI increased significantly at both the country and biome scales over the study period. NDVI shows the(More)
Plant roots are the primary site of perception and injury for saline-alkaline stress. The current knowledge of saline-alkaline stress transcriptome is mostly focused on saline (NaCl) stress and only limited information on alkaline (NaHCO3) stress is available. Using Affymetrix® Soybean GeneChip®, we conducted transcriptional profiling on Glycine soja roots(More)
MicroRNAs (miRNAs) are small single-stranded RNAs with a length of about 21 nt; these non-coding RNAs regulate developmental and stress responses in plants by cleaving mRNAs. Cold stress is one of the most severe abiotic stresses and adversely affects rice yields by restraining sowing time, causing tissue damage, and stunting growth. Although many miRNAs(More)
The WRKY-type transcription factors are involved in plant development and stress responses, but how the regulation of stress tolerance is related to plant development is largely unknown. GsWRKY20 was initially identified as a stress response gene using large-scale Glycine soja microarrays. Quantitative reverse transcription-PCR (qRT-PCR) showed that the(More)
The Ca2+ release-activated Ca2+ (CRAC) channel pore is formed by Orai1 and gated by STIM1 after intracellular Ca2+ store depletion. To resolve how many STIM1 molecules are required to open a CRAC channel, we fused different numbers of Orai1 subunits with functional two-tandem cytoplasmic domains of STIM1 (residues 336-485, designated as S domain).(More)
A total of 171 Streptococcus pneumoniae isolates causing invasive disease were isolated from Chinese children. The serotype distribution and antimicrobial resistance were tested. The results suggested that the 7-valent pneumococcal conjugate vaccine has a preventive effect among children and that there should be long-term surveillance for serotype 19A.
Salinity and alkalinity are the two main environmental factors that limit rice production. Better understanding of the mechanisms responsible for salinity and alkaline stress tolerance would allow researchers to modify rice to increase its resistance to salinity and alkaline stress. MicroRNAs (miRNAs) are ~21-nucleotide RNAs that are ubiquitous regulators(More)
Two proteins, STIM1 in the endoplasmic reticulum and Orai1 in the plasma membrane, are required for the activation of Ca(2+) release-activated Ca(2+) (CRAC) channels at the cell surface. How these proteins interact to assemble functional CRAC channels has remained uncertain. Here, we determine how many Orai1 and STIM1 molecules are required to form a(More)
