Objective The molecular basis for opiate tolerance and dependence remains poorly understood despite extensive investigation in several preparations, including the hippocampus. Recent studies have implicated that the hippocampus played a central role in opiate tolerance, dependence and withdrawal. The current study is to explore the change in guanine nucleotide binding protein-inhabitant (Gi_2) protein in primary cultured hippocampal neurons with morphine treament. Methods The hippocampus was harvested from newborn Sprague-Dawley rats. Primary hippocampal neuronal cultures of 7 days in vitro were used and divided randomly into six groups (n=6), i.e. morphine treatment 4h group (M4), 8h group (M8), 16h group (M16), 24h group (M24), 48h group (M48) and control group (C). All morphine treatment groups were treated with morphine (10?mol/L). C group was treated with saline. The G protein levels were determined with immunofluorscence and laser scanning confocal microscope (LSCM) imaging techniques. Results Gi_2 protein levels in M16, M24 and M48 groups decreased significantly compared with that in C group (P0.05). Among M16, M24 and M48 groups, Gi_2 protein level was lowest in the M48 group. Conclusion The results indicated that Gi_2 protein levels decreased significantly in primary cultured hippocampal neurons with morphine treatment, which might be a potential molecular mechanism of opioid tolerance and dependence.

Aim To assess the effects of N -[2-p-bromo-cinnamylamino-ethyl]-5-isoquinoline-sulfonamide (H-89), a potentially selective inhibitor of Protein Kinase A (PKA), on cardiac membrane ion channels and transporters, which will further fulfill our understanding of pharmacology of PKA inhibitors.Methods Whole-cell patch clamp was used to investigate the effects of H-89 on cardiac L-type Ca~(2+) current (I_(Ca-L)), Na~+ current (I_(Na)), inward rectifier K~+ current (I_(K1)), transient outward K~+ current (I_(to)) and Na~+-Ca~2+ exchanger current (I_(Na/Ca)) in enzymatic dissociated SD rat ventricular myocytes.Results H-89 at 1~10 μmol·L~(-1) could inhibit I_(Ca-L) , I_(Na) , and Ito in a concentration-relative manner (P <0.05). At low concentra-tion (5 μmol·L~(-1)), H-89 completely inhibited I_(K1) (P <0.05) just as the action of 0.5 mmol·L~(-1) BaCl_2.Further, H-89 at 1~10 μmol·L~(-1) had no significant effect on I_(Na/Ca) (P >0.05).Conclusion The direct or PKA-mediated indirect action maybe involved in the effects of H-89 on ion currents and transporter.

Objective To observe the permeability and stability of the transfection of antisense oligonucleotide (ASODN) hybridized epidermal growth factor receptor (EGFR) to retinal glial cells (RG). Methods Phosphorothioate and unmodified EGFR ASODN conjugated with 5′ isothiocyanate (5′ FITC) were encapsulated with or without lipofectin, and then added into human retinal glial cells culture media. The cellular permeability and stability of the transfection were observed by fluorescence microscopy in fixed cells. Results In the absence of lipofectin, phosphorothioate and unmodified EGFR ASODN were found in a few RG cells at 30 minutes, and in about 50% RG cells at 4 hours. Phosphorothioate EGFR ASODN were kept in RG cells for 3 4 hours and disappeared at about 8 hours. In the presence of lipofectin, phosphorothioate and unmodified EGFR ASODN were found in a few RG cells at 15 minutes and about 70% 80% RG cells at 4 hours. Phosphorothioate EGFR ASODN were kept in cells for 10 12 hours, and phosphorothioate and unmodified EGFR ASODN were disappeared at about 14 hours and 4 hours respectively. Conclusion 5′ FITC EGFR ASODN encapsulated with lipofectin could enter RG cells and express stably in RG cells.
