When seedlings are grown in the dark, proplastids of the developing leaf differentiate into etioplasts. Greening of etiolated plastids is stimulated by light, which is sensed by various types of photoreceptors. Nitric oxide (NO) has been shown to be a bioactive molecule that could take part in this light-mediated process in plants. In this paper, we show(More)
Calluses from two ecotypes of reed (Phragmites communis Trin.) plant (dune reed [DR] and swamp reed [SR]), which show different sensitivity to salinity, were used to study plant adaptations to salt stress. Under 200 mm NaCl treatment, the sodium (Na) percentage decreased, but the calcium percentage and the potassium (K) to Na ratio increased in the DR(More)
With conserved structural scaffold and divergent electrophysiological functions, animal toxins are considered powerful tools for investigating the basic structure-function relationship of voltage-gated sodium channels. Jingzhaotoxin-III (β-TRTX-Cj1α) is a unique sodium channel gating modifier from the tarantula Chilobrachys jingzhao, because the toxin can(More)
The tarantula Chilobrachys jingzhao is one of the most venomous spiders with a specialized organ, venom gland, which synthesizes and secretes the complex and abundant toxin proteins. The components of the venom have been extensively studied. As far as the molecular mechanism of toxin secretion and metabolism is concerned, we still knew a little. To obtain a(More)
To characterize the role of nitric oxide (NO) in the tolerance of Arabidopsis (Arabidopsis thaliana) to heat shock (HS), we investigated the effects of heat on three types of Arabidopsis seedlings: wild type, noa1(rif1) (for nitric oxide associated1/resistant to inhibition by fosmidomycin1) and nia1nia2 (for nitrate reductase [NR]-defective double mutant),(More)
OBJECTIVES To investigate current evidence linking ischemic postconditioning (IPC) to cardioprotection in patients receiving primary percutaneous coronary intervention (PCI). METHODS We performed searches of PubMed, Embase, MEDLINE and Cochrane databases from January 1998 to May 2011 for identifying relevant studies comparing IPC with usual care in(More)
We previously reported that nitric oxide (NO) functions as a signal in thermotolerance. To illustrate its relationship with hydrogen peroxide (H₂O₂) in the tolerance of Arabidopsis (Arabidopsis thaliana) to heat shock (HS), we investigated the effects of heat on Arabidopsis seedlings of the following types: the wild type; three NADPH oxidase-defective(More)
TNF-related apoptosis-inducing ligand (TRAIL) is a tumor-selective cytokine with potential anticancer activity and is currently under clinical testing. Head and neck squamous cell carcinoma (HNSCC), like other cancer types, exhibits varied sensitivity to TRAIL. MLN4924 is a newly developed investigational small molecule inhibitor of NEDD8-activating enzyme(More)
Jingzhaotoxin-34 (JZTX-34) is a 35-residue polypeptide from the venom of Chinese tarantula Chilobrachys jingzhao. Our previous work reported its full-length cDNA sequence encoding a precursor with 87 residues. In this study we report the protein expression and biological function characterization. The toxin was efficiently expressed by the secretary pathway(More)
Autophagy is a cellular lysosomal degradation pathway essential for regulation of cell survival and death to maintain homeostasis. This process is negatively regulated by mammalian target of rapamycin (mTOR) signaling and often counteracts efficacy of certain cancer therapeutic agents. NVP-BEZ235 (BEZ235) is a novel, orally bioavailable dual PI3K/mTOR(More)
