Objective
Our aim was to explore whether heat stress protein (HSP) 9 preferentially expresses under heat stress and affects the expression of other heat stress proteins as well as to explore the effect of HSPB9 overexpression and knockdown on apoptosis in DF-1.Methods
We used gene cloning to construct an overexpression vector of the target gene, and synthesized the target gene interference fragment to transfect the chicken fibroblast cell line. Gene and protein expression, as well as apoptosis, were detected by RT-qPCR, Western blot, and flow cytometry.Results
Chicken DF-1 cells showed an early state of apoptosis in the early stages of HSPB9 overexpression. In the later stages, as HSPB9 expression increased, the cells showed inhibition of apoptosis. When the cells were under heat stress, HSPB9 expression was much higher and earlier than the expression of HSPB1 and HSPA2. In addition, high expression of HSPB9 had a negative effect on HSPB1 and HSPA2 expression. This negative feedback decreased the percentage of early stages of apoptotic cells and promoted cell survival.Conclusion
HSPB9 expression, although rapid, is detrimental to cell survival early during its overexpression. In heat stress, HSPB9 overexpression, while inhibiting the expression of HSPA2 and HSPB1, is beneficial to cell survival. 相似文献2.
Objective
To observe the regulation of electroacupuncture on gene expression at calcium signaling pathways in mice with cerebral ischemia reperfusion.Methods
Sixty male, inbred Kunming mice were randomly assigned to three groups: repeated cerebral ischemia reperfusion group (RG, n = 24), sham-operated group (SG, n = 12), and electroacupuncture group (EG, n = 24). Mice in RG and EG groups were modeled by repeated cerebral ischemia reperfusion surgery, and EG mice were treated with electroacupuncture for 30 min after recovery from anesthesia. Changes in gene expression profile of mice hippocampi were analyzed by global expression profile microarray. Genes that were up-regulated or down-regulated greater than 1.5 folds were considered to be biologically meaningful. Real-time quantitative polymerase chain reaction (q-PCR) method was used to verify the expression of selected genes based on the algorithm [2^ (12Ct)].Results
Compared with SG mice, 242 genes showed different in expressions in RG mice: 107 down-regulated and 135 up-regulated. Compared with RG mice, 609 genes showed a difference of expression in EG mice: 315 down-regulated and 375 up-regulated. Gene ontology and Kyoto Encyclopedia of Genes and Genomes analyses indicated two pathways: calcium signaling and long-term potentiation in which 11 differentially expressed genes selected. Six of the 11 genes in the calcium signaling pathway were verified after real-time q-PCR testing.Conclusion
Electroacupuncture treatment of cerebral ischemia reperfusion appears to regulate Atp2a2, Cacna1e, Camk2a, Gnas, Grm1, Rapgef3 genes in the calcium signaling pathway. 相似文献3.
OBJECTIVE
To investigate the effect of brain functional recovery decoction (BFRD) on expression of vascular endothelial growth factor (VEGF) and angiopoietin-1 (Ang-1) protein in rats with cerebral ischemia reperfusion injury, and to explore the mechanism of action of BFRD.METHODS
Using the suture-occlusion method, a Wistar rat model of focal cerebral ischemia reperfusion was established. The rats were randomly divided into treatment group, model group, and sham operation group. The treatment group was administered BFRD. In situ hybridization was used to detect VEGF mRNA expression. Immunohistochemistry was used to observe expression of Ang-1 protein.RESULTS
VEGF mRNA expression was greater in the model group compared with the sham operation group (P < 0.05); Ang-1 protein expression was more obvious in the treatment group than the model group (P< 0.05).CONCLUSION
BFRD promoted VEGF mRNA and Ang-1 protein expression in the brains of rats with cerebral ischemia, suggesting increased angiogenesis. 相似文献4.

Objective
To evaluate the effects of baicalin in human gastric cancer cells, including apoptosis-inducing effects, and to investigate its underlying mechanisms of action.Methods
Cell proliferation and apoptosis assays were performed to investigate the anti-proliferation effects of baicalin in human gastric cancer BGC-823 and MGC-803 cells. Real time-quantitative polymerase chain reaction and Western blotting analysis were performed to elucidate the molecular mechanisms underlying the anti-tumor properties of baicalin.Results
In BGC-823 and MGC-803 gastric cancer cells treated with 80, 120, and 160 µmol/L baicalin for 48 h, a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay showed that baicalin significantly inhibited cell proliferation in a dose-dependent manner, while flow cytometric analysis demonstrated that baicalin could induce apoptosis, also in a dose-dependent manner. Moreover, baicalin up-regulated the expression of caspase-3, caspase-9, and B cell lymphoma (Bcl-2)-associated X protein and down-regulated the expression of Bcl-2 at both the mRNA and protein level.Conclusion
Baicalin has potential as a therapeutic agent for gastric cancer by inducing apoptosis in cancer cells. 相似文献5.

Objective
The aim of this study is identify the intervention mechanism of the effects of electro-acupuncture on the expression of Ang/Tie-2 mRNA and protein in rats with acute cerebral infarction induced by middle cerebral artery occlusion (MCAO).Methods
Altogether 120 Wistar rats were subjected to MCAO by inserting a nylon filament, and then divided into 3 groups: control group, injured group and electro-acupuncture group. The injured and electro-acupuncture groups were further divided into the following 7 subgroups according to the time after MCAO: 3, 6, 12, 24 h, 3, 7 and 12 day, with 8 rats in each subgroup. The electro-acupuncture group was given electro-acupuncture treatment at Shuigou (GV 26) instantly after operation. The rats were killed at different time points according to their groups, and then the expression levels of Ang/Tie-2 mRNA and protein were detected using Real-Time PCR and immunohistochemical staining.Results
The mRNA and protein expression levels of Ang/Tie-2 in the electro-acupuncture group were significant higher than that in the injured group.Conclusion
The results suggested that electro-acupuncture could significantly regulate the expression of Ang/Tie-2 mRNA and protein in the rats with acute cerebral infarction induced by MCAO, and enhance angiogenesis after ischemic penumbra. 相似文献7.

Objective
To investigating the molecular mechanism of herbal pairs in three types of Chinese medicinals: Qi-tonifying, blood activation, blood-stasis breaking in treatment of coronary heart disease (CHD).Methods
The components of six herbs were searched in Chinese medicine dictionary and their target proteins were found in PubChem. CHD genes were obtained from PubMed gene database. Ingenuity Pathways Analysis was used to build the pharmacological network of three herbal pairs and CHD molecular network. The canonical pathways between each herbal pair network and CHD network was compared to decipher the molecular mechanism on three herbal pairs in treating CHD.Results
The network analysis showed that there were the common signal pathways of three herbal pairs in treating CHD including hypoxia signaling in the cardiovascular system, Hypoxia-inducible factor 1-alpha signaling, glucocorticoid receptor signaling, G-Protein coupled receptor signaling and pregnane X receptor/retinoid X receptor (PXR/RXR) activation. Further to analyze cardiovascular signaling, cytokine signaling and cytokine signaling, the effective molecules for three herbal pairs in treating CHD included HIF1α and estrogen receptor 1, Qi-tonifying herbal pair included albumin and matrix metallopeptidase 2, and blood-activation herbal pair included estrogen receptor 2 and peroxisome proliferator-activated receptor-γ.Conclusion
Each herbal pair can affect some respective CHD-related functions and pathways, meanwhile three herbal pairs exert some mutual effects on CHD-related functions and pathways. Mutual effects of three herbal pairs may be the key components of their total molecular mechanisms and respective effects of each herbal pair may be the characteristic components of their respective molecular mechanism. 相似文献8.

Objective
To evaluate the effects of tetrandrine plus arsenic trioxide on HCC1937 cells, a triple negative breast cancer cell line, and to explore possible mechanisms.Methods
The 3-(4,5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide method was used to compare the antiproliferative effects of tetrandrine, arsenic trioxide alone and tetrandrine plus arsenic trioxide on HCC1937 cells. The median-effect principle (Chou-Talalay combination index method) was used to examine the interaction between the two drugs. Flow cytometry was used to evaluate effects of treatment with tetrandrine, arsenic trioxide or the combination of both on HCC1937 cell apoptosis. Real-time polymerase chain reaction and western blotting were performed to evaluate changes in apoptosis-related gene expression and protein levels.Results
Tetrandrine and arsenic trioxide each inhibited HCC1937 cell proliferation in a dose-dependent manner. The cell inhibition rate of HCC1937 cells treated with a combination of tetrandrine and arsenic trioxide was significantly higher than with either compound alone. The two drugs produced a synergistic effect when the inhibition rate was 20%-40%. Flow cytometry results showed that treatment with the two drugs increased the proportion of apoptotic cells. In the combination treated group, caspase-3 activation and PARP cleavage were significantly higher than in the other groups. Moreover, Bcl-2 and survivin expression were decreased, whereas that of both Bid and Bax was increased.Conclusion
These findings demonstrated that tetrandrine plus arsenic trioxide had synergistic efficacy on induction of apoptosis in HCC1937 cells. 相似文献12.

Objective
To investigate the effect of Sharbat-e-Deenar (SD) on acetaminophen (APAP)-induced hepatotoxicity in rat model.Methods
Albino rats were treated with SD at the doses of 1, 2 and 4 mL/kg, p.o. against hepatotoxicity after APAP (2 g/kg, p.o. once only) intoxication. The blood, tissue biochemical parameters and histopathological observation were performed. TheResults
APAP exposure in rats significantly increased the level of biochemical parameters such as aspartate aminotransaminase, alanine aminotransaminase, lactate dehydrogenase, serum alkaline phosphatase, bilirubin, urea and creatinine into blood circulation which were reversed towards normal by SD therapy at all doses. The tissue biochemical parameters such as lipid peroxidation, reduced glutathione, adenosine tri-phosphatase and glucose-6-phosphatase were significantly restored after SD treatment against hepatotoxity. Histological analysis confirmed that SD-treated rats significantly alleviated of liver damage and reduced lesions caused by APAP intoxication. The biochemical changes are in good correlation with the histopathological observations.Conclusion
On the basis of these results, it can be concluded that SD exerts hepatoprotective activity against APAP-induced liver injury. 相似文献14.

Objective
To identify the constituents in Shuanghuanglian injection (SHLI) that correlate with anaphylactoid reaction.Methods
Chemical fingerprints of 10 batches SHLI samples were determined by High Performance Liquid Chromatography (HPLC), and further investigated by similarity analysis. Combined with optical microscopy, both anaphylactoid experiments and confirmatory assay were displayed in Rat basophil leukemia cells (RBL-2H3) to obtain the histamine release inducing by SHLI. The content of histamine was tested by Enzyme-Linked Immuno Sorbent Assay method. Partial least squares regression (PLSR) method and HPLC-DAD-ESI-MSn technology were conducted to analyze constituents in SHLI involving anaphylactoid reaction.Results
The results of spectrum and effect relationships showed that the eight constituents were positively correlated with anaphylactoid reaction. Among which, nearly 90% of them were identified as baicalin and rutin with PLSR and HPLC-DAD-ESI-MSn. This result was in accordance with confirmatory assay on RBL-2H3 cells.Conclusion
Baicalin and rutin from SHLI were the main constituents involving anaphylactoid reaction. 相似文献15.

Objective
To examine the influence of cupping on the quality of life of healthy people who referred to traditional Persian medicine clinics in Tehran.Methods
All participants were examined by Traditional Persian Medicine specialists and their temperaments were determined. The area between the shoulders was cleaned, and cupping was performed with a disposable cupping glass for a few minutes. The questionnaire used in this project was the Persian version of the SF-36 questionnaire which assesses people's understanding of their health status. Before cupping and then one month after cupping, all participants were called and the questionnaires were completed again. Finally, all given data was analyzed.Results
From a total of 290 questionnaires completed in the first phase of the project, 112 patients were excluded. Ultimately, the data of 178 participants was analyzed. After one month, the quality of life score of 155 participants (88%) increased, remained unchanged for 21 participants (11.7%), and decreased for 2 participants (1.1%). Asked about possible complications from cupping, 160 participants reported no side effects (89.9%).Conclusion
Our findings suggest that cupping therapy can improve the scores of quality of life in the participants in Tehran. 相似文献19.
