TRP14 inhibits osteoclast differentiation via its catalytic activity.

We previously reported the inhibitory role of thioredoxin-related protein of 14 kDa (TRP14), a novel disulfide reductase, in nuclear factor-κB (NF-κB) activation, but its biological function has remained to be explored. Here, we evaluated the role of TRP14 in the differentiation and function of osteoclasts (OCs), for which NF-κB and cellular redox regulation have been known to be crucial, using RAW 264.7 macrophage cells expressing wild-type TRP14 or a catalytically inactive mutant, as well as its small interfering RNA.

Protein interactome analysis of 12 mitogen-activated protein kinase kinase kinase in rice using a yeast two-hybrid system.

The mitogen-activated protein kinase (MAPK) cascade is composed at least of MAP3K (for MAPK kinase kinase), MAP2K, and MAPK family modules. These components together play a central role in mediating extracellular signals to the cell and vice versa by interacting with their partner proteins. However, the MAP3K-interacting proteins remain poorly investigated in plants.

Specific detection of Xanthomonas oryzae pv. oryzicola in infected rice plant by use of PCR assay targeting a membrane fusion protein gene.

Successful control of Xanthomonas oryzae pv. oryzicola, the causal agent of bacterial leaf streak, requires a specific and reliable diagnostic tool. A pathovar-specific PCR assay was developed for the rapid and accurate detection of the plant pathogenic bacterium Xanthomonas oryzae pv.

PCR-based specific detection of Ralstonia solanacearum by amplification of cytochrome c1 signal peptide sequences.

A polymerase chain reaction (PCR)-based method was developed to detect the DNA of Ralstonia solanacearum, the causal agent of bacterial wilt in various crop plants. One pair of primers (RALSF and RALSR), designed using cytochrome c1 signal peptide sequences specific to R. solanacearum, produced a PCR product of 932 bp from 13 isolates of R.

Sensitive and specific detection of Xanthomonas campestris pv. vesicatoria by PCR using pathovar-specific primers based on rhs family gene sequences.

The present study describes PCR assay to detect bacterial spot caused by Xanthomonas campestris pv. vesicatoria in pepper and tomato. One set of PCR primer was developed to amplify gene required for an rhs family gene homologous to rhsA, cell envelope biogenesis, outer membrane.

The rice (Oryza sativa) blast lesion mimic mutant, blm, may confer resistance to blast pathogens by triggering multiple defense-associated signaling pathways.

Here we characterized a rice (Oryza sativa L.) blast lesion mimic (blm) mutant, identified previously in an N-methyl-N-nitrosourea-mutagenized population of the cultivar Hwacheong (wild type). The rice blm displayed spontaneous necrotic lesion formation on the leaves during development under long-day condition and temperature shift from 28 to 24 degrees C in the absence of obvious stress/disease, and provided us with a highly reproducible and convenient experimental system in the growth chamber to study blm.

Activation of protein kinase C-delta attenuates kainate-induced cell death of cortical neurons.

We investigated the role of individual protein kinase C (PKC) isoforms during kainate toxicity in cortical neurons. Treatment with 50 microM kainate induced isoform-specific activation of PKC-delta according to the translocation from the soluble to the particulate fraction, while it caused remarkable decreases in PKC alpha, beta, epsilon and zeta in both fractions. Kainate-induced neuronal death was significantly increased by pharmacological inhibition of PKC-delta with rottlerin, suggesting a protective role of PKC-delta against kainate toxicity.
