ObjectiveTo study the effect of 8-Br-cAMP and isopentenyl pyrophosphate (IPP) on the ex pression tau protein in various neural cell lines at the level of signal transdu ction. MethodsNG108-15, PC12 and SH-SY5Y cells were treated with 8-Br-cAMP and IPP in the 37?C incubator for 30 min, then the tau-enriched samples were analyzed by West ern blot. ResultsSH-SY5Y cells only expressed the isoform of tau protein with the lowest molecul ar weight; PC12 cells mainly expressed high molecular weight tau, and several ot her isoforms of tau; NG108-15 expressed a little of isoform of tau. In the expe rimental conditions, the expression of tau was altered with 8-Br-cAMP and IPP in NG108-15, SH-SY5Y and PC12 cells. Conclusions8-Br-cAMP and IPP does not alter the expression of tau in NG108-15, SH-SY5Y and PC12 cells.

AIM: To study the effect of selective A1 adenosine receptor agonist, 2-chloroadenosine (2-CA), and non-peptide phosphoantigen isopentenyl pyrophosphate (IPP) on the intracellular reactive oxygen species (ROS) at the level of signaling event. METHODS: M1 cell line, derived from a subclone of the SV40-transformed xeroderma pigmentosum (XP) cell line, was treated with 2-CA, 8-br-cAMP, IPP at 37 ℃ incubator for 30 min, and intracellular ROS was measured by flow cytometry and CytoFluorometer. RESULTS: Under an appropriate control, 2-CA and IPP reduced intracellular ROS by 20%-30%. CONCLUSION: The data revealed that 2-CA and IPP inhibited cellular oxidant formation at the level of signaling event, suggesting both may have some anti-oxidant properties in vivo.
