OBJECTIVETo investigate the mechanism by which heat shock protein 90 (HSP90) regulates 26S proteasome in hyperthermia.
METHODSHyperthermic HepG2 cell models established by exposure of the cells to 42 degrees celsius; for 3, 6, 12, and 24 h were examined for production of reactive oxygen species (ROS) and cell proliferation, and the changes in Hsp90α and 26S proteasome were analyzed.
RESULTSROS production in the cells increased significantly after hyperthermia (F=28.958, P<0.001), and the cell proliferation was suppressed progressively as the heat exposure time extended (F=621.704, P<0.001). Hyperthermia up-regulated Hsp90α but decreased the expression level (F=164.174, P<0.001) and activity (F=133.043, P<0.001) of 26S proteasome. The cells transfected with a small interfering RNA targeting Hsp90α also showed significantly decreased expression of 26S proteasome (F=180.231, P<0.001).
CONCLUSIONThe intracellular ROS production increases as the hyperthermia time extends. Heat stress and ROS together cause protein denature, leading to increased HSP90 consumption and further to HSP90 deficiency for maintaining 26S proteasome assembly and stability. The accumulation of denatured protein causes unfolded protein reaction in the cells to eventually result in cell death.

OBJECTIVETo investigate the mechanism and the suppression effect of human cytomegalovirus (HCMV) on hematopoietic system.
METHODSSemi-solid culture system was used to observe the effect of HCMV AD169 strain on colony forming unit granulocyte/macrophage (CFU-GM), CFU-erythroid (CFU-E), CFU-multipotent (CFU-Mix) and CFU-megakaryocyte (CFU-MK) growth. The techniques of in situ polymerase chain reaction (IS-PCR) and polymerase chain reaction (PCR) were used to demonstrate the existence of HCMV DNA in the colony cells of cultured CFU-GM, CFU-Mix, CFU-MK and CFU-E, respectively. The immediate early antigen (IEA) mRNA in CFU-MK and late antigen (LA) mRNA in CFU-E were detected by reverse transcriptase-polymerase chain reaction (RT-PCR). HCMV early protein P52 was detected with immunohistochemical technique.
RESULTSHCMV AD169 suppressed the differentiation and proliferation of CFU-GM, CFU-E, CFU-Mix and CFU-MK in vitro significantly (P < 0.05). The suppression was dose-dependent. HCMV DNA was successfully detected in CFU-GM, CFU-Mix, CFU-MK colony cells from viral infection groups by IS-PCR, and was detected in CFU-E by PCR, while it was negative in blank control or mock control groups. CFU-MK colony cells expressed HCMV IEA mRNA with the size of 340 bp in virus infection groups of 10(3) plague forming unit (PFU), 10(4) PFU and 10(5) PFU, respectively. The HCMV LA mRNA was detected by RT-PCR and was 263 bp long in positive control group of HCMV-infected human embryonic fibroblasts. The expression of HCMV LA mRNA in CFU-E was negative. The early protein P52 of HCMV in 10(4) PFU group was also identified by immunohistochemical staining.
CONCLUSIONHCMV AD169 strains inhibited the differentiation and proliferation of CFU-GM, CFU-E, CFU-Mix and CFU-MK by the infection of the hematopoietic progenitors. HCMV might cause the suppression of hematopoiesis by direct infection, which is thought to be one of the reasons of HCMV infection associated with thrombocytopenia, neutropenia and anemia.

OBJECTIVETo compare the therapeutic effect and adverse effects of two regimens, namely cisplatin and docetaxel (DC) regimen and fluorouracil (PF) regimen, both with concurrent radiotherapy, in the treatment of advanced esophageal squamous cancer.
METHODSForty-eight patients with esophageal squamous cancer were randomly assigned in DC regimen and PF regimen groups. All the patients received conventional radiotherapy at a total dose of 60 Gy (in 30 fractions) for 6 weeks. In DC regimen group, the patients received intravenous infusion of docetaxel (75 mg/m(2)) for 1 h on day 1 and DDP (25 mg/m(2) daily) on days 1-3, with every 28 days as one cycle. PF regimen consisted of cisplatin (25 mg/m(2)) on days 1-3 and continuous intravenous infusion of fluorouracil (500 mg/m(2)) for 5 days, with every 28 days as one cycle. All the patients were suggested to have no less than 2 cycles.
RESULTSThe 3-year median survival time in DC regimen was slightly longer than that in PF regimen group (26 vs 23 months, Χ2=3.4041, P=0.065). The same result was also found in the short-term effect and adverse reactions including ?myelosuppression and gastrointestinal reactions. Only the adverse reaction of radiotherapy-induced esophagitis showed a significant difference between the two groups (P=0.049).
CONCLUSIONDC regimen with synchronous radiotherapy is effective and safe for treating advanced esophageal squamous cancer.

Objective To explore whether alcohol promotes the development of breast cancer in TA2 mice and the possible potential mechanism. Methods Thirty-two 6-8-week old nulliparous female TA2 mice were randomly divided into control and ethanol-exposure groups, 16 mice in each group. The mice of the ethanol-exposure group were given 2%ethanol in drinking water, and the mice of control group received regular drinking water. Serum ethanol concentration in the TA2 mice was measured using an ANALOX AM1 alcohol analyzer. The incidence of breast cancer, tumor growth rate and tumor size of the ethanol-exposure and control groups were observed and compared. The estrogen levels of the two groups was detected by enzyme-linked immunosorbent assay ( ELASA) . Results Compared with the control group, the tumor for-mation rate of spontaneous breast cancer in the alcohol-exposure group was significantly increased (62. 5% vs. 43. 75%, P<0. 05), the average number of days of tumor formation was shortened (285 days vs. 335 days, P<0. 05), the tumor weight and volume were increased but not significant ( P>0. 05 ) , and the level of estrogen in the ethanol-exposure mice was significantly higher than that in the control group ( P>0. 05 ) . Conclusions Alcohol promotes the tumorigenesis of spontaneous breast cancer in TA2 mice, which may be associated to the increase of estrogen levels.

BACKGROUNDNa + /Ca 2+ exchanger (NCX) plays a crucial role in pentylenetetrazol-induced convulsion. However, it is unclear whether NCX is critically involved in hyperthermia-induced convulsion. In this study, we examined the potential changes in NCX3 in the hippocampus and cerebrocortex of rats with hyperthermia-induced convulsion.
METHODSTwenty-one Sprague Dawley rats were randomly assigned to control group, convulsion-prone group and convulsion-resistant group (n = 7 in each group). Whole-cell patch-clamp method was used to record NCX currents. Both the Western blotting analysis and immunofluorescence labeling techniques were used to examine the expression of NCX3.
RESULTSNCX currents were decreased in rats after febrile convulsion. Compared to the control group, NCX3 expression was decreased by about 40% and 50% in the hippocampus and cerebrocortex of convulsion-prone rats, respectively. Furthermore, the extent of reduction in NCX3 expression seemed to correlate with the number of seizures.
CONCLUSIONSThere is a significant reduction in NCX3 expression in rats with febrile convulsions. Our findings also indicate a potential link between NCX3 expression, febrile convulsion in early childhood, and adult onset of epilepsy.
