Strigolactones (SLs) are a group of newly identified plant hormones that control plant shoot branching. SL signalling requires the hormone-dependent interaction of DWARF 14 (D14), a probable candidate SL receptor, with DWARF 3 (D3), an F-box component of the Skp-Cullin-F-box (SCF) E3 ubiquitin ligase complex. Here we report the characterization of a(More)
Previous studies on diabetes have reported controversial results with regard to transporters in liver. The present study aimed to explore changes in hepatic breast cancer resistance protein (BCRP) expression and functions, as well as the possible underlying mechanisms, in type 2 diabetic patients, type 1 (streptozotocin-induced), and type 2 (Goto Kakizaki)(More)
The effects of Li(+) and polyethylene glycol (PEG) on the genetic transformation of Saccharomyces cerevisiae were investigated by using fluorescence microscopy (FM) to visualize the binding of plasmid DNA labeled with YOYO-1 to the surface of yeast cells, scanning electron microscopy (SEM) and atomic force microscopy (AFM) to image the change in surface(More)
Gracilaria lemaneiformis was exposed to 0, 25, 50, 100, 250 and 500 microg x L(-1) of Cu2+ to study its physiological responses to Cu2+ stress. When the Cu2+ concentration was > or = 50 microg x L(-1), the relative growth rate (RGR) of G. lemaneiformis decreased significantly, and the optimal quantum yield (Fv/Fm), the maximum relative electron transfer(More)
The in vivo and in vitro metabolism of mangiferin was systematically investigated. Urine, plasma, feces, contents of intestinal tract and various organs were collected after oral administration of mangiferin to healthy rats at a dose of 200mg/kg body weight. For comparison, mangiferin was also incubated in vitro with intestinal flora of rats. With the aid(More)
To clarify the role of the intestinal flora in the absorption and metabolism of mangiferin and to elucidate its metabolic fate and pharmacokinetic profile in diabetic rats, a systematic and comparative investigation of the metabolism and pharmacokinetics of mangiferin in conventional rats, pseudo-germ-free rats, and streptozotocin (STZ)-induced diabetic(More)
The present study was designed to reveal the potential role of let-7c-5p, a highly conserved miRNA in stroke. We found that the content of let-7c-5p was significantly decreased in the plasma of patients with ischemic stroke as well as in experimental animals. Moreover, we also observed a significant decrease of let-7c-5p in ipsilateral cortex and striatum(More)
Heat shock proteins (HSPs) play crucial roles in protecting cells against environmental stresses, such as heat shock, heavy metals and pathogenic bacteria. Among the HSP family, the 70-kDa HSPs are most responsible for intracellular chaperone and extracellular immunoregulatory functions. The full-length HSP70 cDNA of Mytilus coruscus (designated as McHSP70,(More)
Superoxide dismutases (SODs) are ubiquitous family of metalloenzymes involved in protecting organisms from excess reactive oxygen species damage. In this paper, a novel intracellular Cu/ZnSOD from Sepiella maindroni (designated as SmSOD) was identified and characterized. The full-length cDNA sequence of SmSOD (GenBank accession No. KF908850) was 709 bp(More)
