Interleukin-17A and interleukin-17F (IL-17A and IL-17F) are candidate genes for chronic inflammatory disease. We investigated the association between IL17A/F gene polymorphisms and susceptibility to and clinical features of inflammatory bowel disease (IBD). A total of 270 ulcerative colitis (UC) patients, 82 Crohn’s disease (CD) patients and 268 healthy(More)
BACKGROUND Previous studies implicated that IL23R and IL17 genes play an important role in autoimmune inflammation. Genome-wide association studies have also identified multiple single nucleotide polymorphisms (SNPs) in the IL23R gene region associated with inflammatory bowel diseases. This study examined the association of IL23R and IL17A gene SNPs with(More)
BACKGROUND AND AIMS Uncoupling protein-2 (UCP-2) is a negative regulator of reactive oxygen species (ROS) production. We investigated the effect of UCP-2 on disease progression in a murine dextran sodium sulfate (DSS)-induced colitis model, and the expression and distribution of tight junction (TJ) proteins, such as occludin, zonula-1 (ZO-1), claudin-4, and(More)
Copper (Cu) is an important environmental pollutant that exerts harmful effects on all living organisms when in excess. In an effort to remove this toxin in situ, a bacterial Cu-binding protein gene CusF was engineered to target CusF for secretion to the cell wall and vacuoles and for accumulation in the cytoplasm. Analysis of transgenic Arabidopsis plants(More)
Cadmium (Cd) is a transition metal that is highly toxic in biological systems. Anthropogenic emissions of Cd have increased biogeochemical cycling and the amount of Cd in the biosphere. Here we studied the utility of a bacterial Cd-binding protein, CadR, for the remediation of Cd contamination. CadR was successfully targeted to chloroplasts using a(More)
The periplasmic protein CusF acts as a metallochaperone to mediate Cu resistance in Escherichia coli. CusF does not contain cysteine residues and barely binds to divalent cations. Here, we addressed effects of cysteine-substitution mutant (named as mCusF) of CusF on zinc/cadmium (Zn/Cd) accumulation and resistance. We targeted mCusF to different subcellular(More)
Systemin (SYS), an octadecapeptide hormone processed from a 200-amino-acid precursor (prosystemin, PS), plays a central role in the systemic activation of defense genes in tomato in response to herbivore and pathogen attacks. However, whether PS mRNA is transferable and its role in systemic defense responses remain unknown. We created the transgenic tomato(More)
