The CBL-CIPK signaling pathway represents a central and critical signaling system involved in plant response to abiotic stress and hormone signaling. In this study, we focused on AtCIPK6 gene, which have been shown to be required for development and salt tolerance in Arabidopsis, but the transcriptional regulatory mechanism of AtCIPK6 gene and whether it(More)
High salinity and drought are the major abiotic stresses that adversely affect plant growth and agricultural productivity. To investigate genes that are involved in response to abiotic stresses in Brassica napus, a comprehensive survey of genes induced by high-salinity and drought stresses was done by macroarray analysis. In total, 536 clones were(More)
Androgens via their cognate receptor may be involved in the development and progression of prostate cancer. The aim of this study was to determine whether tea polyphenols have inhibitory effects on androgen action in an androgen-responsive, prostate cancer cell line, LNCaP. The tea polyphenol, EGCG, inhibited LNCaP cell growth and the expression of androgen(More)
Heme oxygenase-1 (HO-1), the rate-limiting enzyme in heme catabolism, has been shown to be induced during oxidative injury, and its induction acts as an important cellular defense mechanism against such injuries. In this study, we examined the functional roles of HO-1 induction in a rat model of d-galactosamine (GalN) and lipopolysaccharide (LPS)-induced(More)
A CBL-interacting protein kinase (CIPK) gene, BnCIPK6, was isolated in Brassica napus. Through yeast two-hybrid screening, 27 interaction partners (including BnCBL1) of BnCIPK6 were identified in Brassica napus. Interaction of BnCIPK6 and BnCBL1 was further confirmed by BiFC (bimolecular fluorescence complementation) in plant cells. Expressions of BnCIPK6(More)
BACKGROUND Although endoplasmic reticulum (ER) stress has been implicated in the pathophysiology of organ ischemia-reperfusion injury (IRI), the underlying mechanisms have yet to be fully elucidated. In particular, because tissue proinflammatory immune response is the key mediator of local IRI, how ER stress impacts liver immune cell activation cascade(More)
Plant salt tolerance is a complex trait involving many genes. To identify new salt tolerance determinants during seed germination, we have screened a population of chemically inducible activation-tagged Arabidopsis mutants. A mutant, designated stg1 (salt tolerance during germination 1), was obtained. The stg1 mutant is less sensitive than the wild type to(More)
Adinbitor was cloned from Agkistrodon halys brevicaudus stejneger and characterized as a novel disintegrin. In this study, total RNA was extracted from venom gland and used in RT-PCR to generate a cDNA which is 219 bp long. The sequence encoded a polypeptide composed of 73 amino acids, including 12 cysteines, an RGD motif, and the signature motif of(More)
UNLABELLED The ubiquitous serine/threonine kinase glycogen synthase kinase 3 beta (Gsk3β) differentially regulates macrophage Toll-like receptor (TLR)-triggered pro- and anti-inflammatory cytokine programs. This study was designed to determine the in vivo role and therapeutic potential of Gsk3β modulation in tissue inflammation and injury in a murine model(More)
Hydrogen peroxide (H2O2) as a widespread molecule plays an important role in plant stress responses. Here, we showed that an Arabidopsis line overexpressing hemoglobin 1 (AtGLB1) can enhance its tolerance to severe hypoxic stress. In our research, Arabidopsis lines with different hemoglobin levels were employed to study the relationship between H2O2 level(More)
