Drought is a major threat to plant growth and crop productivity. Calcium-dependent protein kinases (CDPKs, CPKs) are believed to play important roles in plant responses to drought stress. Here, we report that Arabidopsis thaliana CPK8 functions in abscisic acid (ABA)- and Ca(2+)-mediated plant responses to drought stress. The cpk8 mutant was more sensitive(More)
The p38 pathway, which is important in mitogen-activated protein kinase (MAPK) family protein signaling, leads to mitochondrial dysfunction and activation of caspase-3. B-cell lymphoma 2 (Bcl‑2) family members are involved in the regulation of activities associated with the survival and death of neurons through apoptosis and have important functions in most(More)
OBJECTIVE To investigate the effects of the micrometer compound rhizoma coptidis on inflammatory factors and its possible mechanism in rabbit fed with high-lipid food. METHOD The levels of CRP, IL-1 and TNF-alpha were all determinated by ELISA method. The mRNA and activity of NF-kappaB were determinated by RT-PCR and EMSA, respectively. RESULT The level(More)
Alzheimer's disease (AD) is accompanied by enhanced oxidative stress and excess free radicals. Phosphodiesterase 9 inhibitors (PDE-9Is) showed memory improving effects in many pharmacological deficit models. However, whether BAY 73-6691 (a selective PDE-9I) may attenuate the oxidative stress during the development of AD is still unclear. For this purpose,(More)
