OBJECTIVETo study the influence of human cytomegalovirus (HCMV) infection on cell cycle and the expression of replication licensing factor Cdt1 in human embryonic lung fibroblastic (HEL) cells and to explore the pathogenesis of HCMV infection.
METHODSHEL cells were synchronized in the G0/G1 phase by the serum starvation method. The synchronized HEL cells were infected with HCMV, and those that were not subjected to HCMV infection were used as the control group. The HEL cells were harvested at 12, 24, 48, 72 and 96 hrs of HCMV infection. The cell cycle of HEL cells was detected by the flow cytometry. The expression of Cdt1 mRNA in HEL cells was determined by reverse transcription-polymerase chain reaction (RT-PCR).
RESULTSThe cells in the G1 phase in the control group was significantly more than in the HCMV-infected group 12 and 24 hrs after infection (P < 0.01). The expression of Cdt1 mRNA in the HCMV-infected group was significantly lower 12 and 24 hrs after infection but increased significantly 48 hrs after infection compared with the control group (P < 0.05). The expression of Cdt1 mRNA reached a peak at 12 hrs of infection in the control group, but at 48 hrs of infection in the HCMV-infected group, which markedly lagged behind the control group.
CONCLUSIONSHCMV infection arrests the cell cycle of HEL cells at the G1 phase. HCMV infection makes Cdt1 expression delay. HCMV infection can interfere cell cycle of HEL cells possibly through affecting the expression of Cdt1.

The purpose of this study was to determine whether the Ca2+ signaling pathway is involved in the ability of osteoprotegerin (OPG) to inhibit osteoclast differentiation and maturation. RAW264.7 cells were incubated with macrophage colony-stimulating factor (M-CSF) + receptor activator of nuclear factor-kappaB ligand (RANKL) to stimulate osteoclastogenesis and then treated with different concentrations of OPG, an inhibitor of osteoclast differentiation. The intracellular Ca2+ concentration [Ca2+]i and phosphorylation of Ca2+/calmodulin-dependent protein kinase II (CaMKII) in the different treatment groups were measured by flow cytometry and Western blotting, respectively. The results confirmed that M-CSF + RANKL significantly increased [Ca2+]i and CaMKII phosphorylation in osteoclasts (p < 0.01), and that these effects were subsequently decreased by OPG treatment. Exposure to specific inhibitors of the Ca2+ signaling pathway revealed that these changes varied between the different OPG treatment groups. Findings from the present study indicated that the Ca2+ signaling pathway is involved in both the regulation of osteoclastogenesis as well as inhibition of osteoclast differentiation and activation by OPG.

OBJECTIVETo investigate the cytotoxic mechanism of cadmium (Cd) on cerebral cortical neurons.
METHODSThe primary cultures of rat cerebral cortical neurons were treated with different concentrations of cadmium acetate (0, 5, 10, and 20 micromol/L), and then the cell viability, apoptosis, ultrastructure, intracellular [Ca2+], and reactive oxygen species (ROS) levels, mitochondrial membrane potential (delta psi), activities of catalase (CAT) and superoxide dismutase (SOD) were measured.
RESULTSA progressive loss in cell viability and an increased number of apoptotic cells were observed. In addition, Cd-induced apoptotic morphological changes in cerebral cortical neurons were also demonstrated by Hoechst 33258 staining. Meanwhile, ultrastructural changes were distortion of mitochondrial cristae and an unusual arrangement. Simultaneously, elevation of intracellular [Ca2+]i and ROS levels, depletion of Delta Psi were revealed in a dose-dependent manner during the exposure. Moreover, CAT and SOD activities in the living cells increased significantly.
CONCLUSIONExposure of cortical neurons to different doses of Cd led to cellular death, mediated by an apoptotic mechanism, and the apoptotic death induced by oxidative stress may be a potential reason. And the disorder of intracellular homeostasis caused by oxidative stress and mitochondrial dysfunction may be a trigger for apoptosis in cortical neurons.
