Glial cell line-derived neurotrophic factor (GDNF) has potentially great clinical importance in the treatment of Parkinson's disease and several other neurodegenerative diseases, however its intracellular signaling mechanisms are poorly understood. Here we show that upon GDNF binding glycosyl-phosphatidylinositol (GPI)-linked GDNF receptor alpha1(More)
Neuronal cell death is in many cases regulated by competitive interactions between pro- and antiapoptotic proteins of the Bcl-2 family. In this study we have identified two splice variants of the rat proapoptotic molecule Bad, which differ in their carboxy-terminal regions. Both splice variants of Bad interacted with the antiapoptotic molecule Bcl-w as(More)
We have identified and characterized N-Bak, a neuron-specific isoform of the pro-apoptotic Bcl-2 family member Bak. N-Bak is generated by neuron-specific splicing of a novel 20-base pair exon, which changes the previously described Bak, containing Bcl-2 homology (BH) domains BH1, BH2, and BH3, into a shorter BH3-only protein. As demonstrated by reverse(More)
Hydrogen peroxide (H2O2) and nitric oxide (NO) function as signal molecules in plant cells. Recently, hydrogen sulfide (H2S) has been found to have similar functions, but their interactions in the acquisition of thermotolerance in plants remain elusive. In current work, pretreatment with H2O2 rapidly induced endogenous H2O2 accumulation, which in turn(More)
Plant C2 domain proteins play important roles in diverse cellular processes including growth, development, and membrane targeting, as well as in abiotic and biotic stress adaptations by sensing intracellular Ca2+ signals. In this study, we isolated a novel C2 domain protein gene, TaERG3, from wheat infected by Puccinia striiformis f. sp. tritici. TaERG3 was(More)
Nitric oxide (NO) and 5-aminolevulinic acid (5ALA) play fundamental roles in plant responses to environmental stresses, but their cross-talk in antioxidant defense in cold-stressed Elymus nutans Griseb. have not been investigated. We herein report that 5ALA and NO donor, sodium nitroprusside (SNP), alleviated cold stress-induced plant growth inhibition and(More)
