AIM To understand the mechanism of the transactivation of the epidermal growth factor receptor (EGFR) mediated by the adenosine A(1) receptor (A(1)R). METHODS Primary cultured rat cortical neurons subjected to oxygen-glucose deprivation (OGD) and HEK293/A(1)R cells were treated with the A(1)R-specific agonist N(6)-cyclopentyladenosine (CPA). Phospho-EGFR,(More)
The present study was designed to examine the effects of adenosine A(1) receptor on dopamine D(1) receptor desensitization in a human embryonic kidney 293 cell line stably cotransfected with human adenosine A(1) receptor and dopamine D(1) receptor cDNAs (A(1)D(1) cells) by means of cAMP accumulation assay. Long-term exposure of A(1)D(1) cells to dopamine(More)
In higher plants, ADP-glucose pyrophosphorylase (EC 2.7.7.27, AGPase), a heterotetrameric enzyme comprised of two small and two large subunits, carries out the first committed step of starch synthesis. To characterize the AGPase genes in lotus, we cloned a small subunit and a large subunit of AGPase using the rapid amplification of cDNA ends (RACE)(More)
Western blot has been used to study the time-course effect of the two most popular parkinsonian neurotoxins, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, i.p.) and 6-hydroxydopamine (6-OHDA, intra-substantia nigra), on the expression of several regulators of G-protein signaling (RGS2, 4 and 9) in striatum in rodents. During the few days after MPTP(More)
