BACKGROUND: The prevalences of hypertension, cerebrovascular diseases, etc. are higher in Mongolian population because of the influence of various factors including genetics, geography, diet, etc. Therefore, it is helpful to develop researches on the genetics of various diseases including hypertension in Mongolian population. OBJECTIVE: To analyze the association between the polymorphism of beta1 adrenergic receptor (β1-AR) gene G1165C (Arg389Gly), an important candidate gene for various diseases of cardiovascular system, and essential hypertension in Mongolian population. DESIGN : A cross-sectional study SETTINGS: Department of Neurology, the First Affiliated Hospital of Inner Mongolia Medical College; Wulate Houqi Red Cross Society. PARTICIPANTS: The survey was carried out from February 2003 to March 2005. Totally 239 Mongolian residents, whose blood relations of 3 generations were all Mongolians, were selected from Wulate Houqi, Inner Mongolia, and they were all informed with the survey and detected items. Based on the diagnostic standard of hypertension set by WHO in 1999, the subjects were divided into two groups according to the level blood pressure: ① Normal blood pressure group (n=117): systolic blood pressure (SBP) 〈 140 mm Hg (1 mm Hg =0.133 kPa), diastolic blood pressure (DBP) 〈 90 mm Hg, and those having histories of cerebrovascular disease, heart disease, diseases of liver, kidney and tiroides, and diabetes mellitus were excluded. ② Essential hypertension group (n=122): including 51 patients with simple high SBP. All the enrolled subjects had no blood relationship with each other, and had no history of miscegenation. METHODS : The body height, body mass, waist circumference and blood lipids were measured routinely, and their habits of smoking and drinking were also investigated. Penpheral venous blood (5 mL) was drawn, the genome DNA was extracted, and the polymorphisms of the β1-AR Gl165C (Gly389Arg) genotype were detected with the Sequenom system. Polymerase chain reaction (PCR) experiment and SNP detection were performed in Huada Gene Laboratory of Bejing, then the univariate analysis of variance was applied in the sample comparison among groups, and the chi-square test was used to compare the genotypes and allele frequencies. The odd ratio (OR) and 95% confidence interval (CO were calculated. MAIN OUTCOME MEASURES: The distributions of β1-AR Gl165C (Gly389Arg) genotypes and alleles were observed. RESULTS: A11 the 239 subjects were involved in the analysis of results, and no one missed, ①Comparison of β1-AR G1165C (Gly389Arg) genotypes and allele distnbutions: In Mongolian population, the frequencies of CC and GG+GC genotypes at β1-AR G1165C (Gly389Arg) site in the essential hypertension group (72%, 28%) were not significantly different from those in the normal blood pressure group (67%, 33%) (xz=0.841, P=-0.359; OR 0.773, 95%Cl: 0.445-1.342); The frequencies of C and G alleles also had no significant differences between the essential hypertension group (85%, 15%) and the normal blood pressure group (82%, 18%) (x^2=1.136, P=-0.287; OR: 0.769, 95%Cl: 0.747-1.248). ②The frequencies of CC and GG+GC genotypes at β1-AR G1165C (Gly389Arg) site had no significant differences between the patients with simple high SBP (71%, 29%) and the normal blood pressure group (x^2=0.250, P=-0.617; OR: 0.833, 95%C/: 0.408-1.703); The frequencies of C and G alleles were not significantly different between the patients with simple high SBP (86%, 14%) and the normal blood pressure group (x^2=0.670, P=-0.413; OR 0.766, 95%Cl: 0.404-1.453). CONCLUSION: In Mongolian population, the distributions of the genotypes and alleles of β1-AR Gl165C (Gly389Arg) have no obvious differences between the subjects with normal blood pressure and the patients with essential hypertension (including simple SBP increase), which suggests that G1165C (Glu389Asp) site of β1-AR gene may be not a genetic mark of essential hypertension and simple high SBP in Mongolian population. 展开更多

The changes of beta-adrenergic receptors (AARs) in lung tissue in endotoxin-induced acute lung injury was investigated with radioligand bindig assay in rats. The lipid fluidity and phospholipid content of the cellular membrane of lung tissue were measured with fluorescent polarization and high performance liquid chromatography respectively. The findings were as follows:1- Four hours after endotoxin injection, there was a 47% decrease of the maximal binding capacity of fyARsas compared with the control.2. Endotoxin was able to decrease the lipid fluidity and phospholipid content of the pulmonary cellular membrane markedly and at the same time. There was an elevated activity of phospholipase A2 in the pulmonary tissueThese findings suggest that the decrease of the binding capacity of &ARs results in a decrease of the PAR mediated functions, which plays a ro1e in the pathogensis of endotoxin-induced acute lung injury and the activation of phospholipase A2 which is an important factor to reduce the phospholipid content of cell membrane and subsequently to decrease its lipid fluidity, can result in a reduction of the lateral diffusion and rotatory movement of β-ARs and to decrease the chances of β-ARs to bind with the ligands. 展开更多

Objective:To investigate the relationship between the levels of plasma adrenaline and norepinephrine and gene polymorphism of β1 adrenergic receptor G1165 C in children with enterovirus 71(EV71) infection in hand foot and mouth disease(HFMD). Methods:The polymerase chain reaction(PCR) was used to detect the expression of gene polymorphism of β1 adrenergic receptor G1165 C in vitro. The levels of plasma adrenaline and norepinephrine were measured by enzyme-linked immunosorbent assay(ELISA). Results:The plasma norepinephrine level of severe group was significantly higher than the mild group in children with EV71 infection in HFMD(P<0.05); however,the levels of plasma adrenalinein in two groups had no statistical differences(P>0.05); There was no significant difference in the distribution of β1 adrenergic receptor G1165 C genotype and allele between EV71 infection group and healthy control group(P> 0.05). Further analysis of EV71 infection group by dividing it into mild and severe groups showed that there was no significant difference in the distribution of genotype and allele between these two groups as well(P> 0.05). There was no significant difference in the levels of epinephrine and norepinephrine in different genotypes of EV71 infection group(P> 0.05),and in the levels of plasma epinephrine and norepinephrine in the mild and severe groups(P> 0.05). Conclusions:As the disease gets worse,the plasma norepinephrine level has a rising trend in children with EV71 infection in HFMD,which is an important indicator to evaluate the progress of the disease. However,the gene polymorphism of eptor G1165 C have no significant correlation,not only with the susceptibility and severit β1 adrenergic recy of EV71 infection in hand,foot and mouth disease,but also with the levels of catecholamine. 展开更多

Beta-adrenergic receptors in the brain are involved in modulating cerebral blood flow (CBF) and cerebral energy metabolism (CEM). Because of the difficult availability of brain tissue samples, investigation of the relevant beta-receptor of brain is limited. In the present study, the density of beta-receptors in brain tissues and in circulating lymphocytes was measured by the method of radio-ligand receptor binding (RLBA), in brain injury or brain tumor and a correlation analysis was performed. Our results show that there is linear correlation between the beta-receptors in brain tissue and in peripheral blood lymphocytes (r= 0. 811 , P<0. 01) in cases of increased permeability of bloodbrain barrier during brain injury or brain tumor. 展开更多

Summary: The experimental results showed that the level of CAMP, the ratio of cAPM to cGMP, IL-2R expression and IL-2 production in vitro in lymphocytes immediate and 2 weeks after car- diopulmonary bypass (CPB) were significantly lower than those before anesthetics in the patients undergoing cardiac surgery with CPB. These findings suggested that CPB could cause serious damage to adrenergic beta receptor-adenylate cyclase system on circulating lymphocytes surfaces, which might be one of the mechanisms resulting in immunosuppression after open heart surgery with CPB. 展开更多

Objective To study the effect of β3 adrenergic receptor (β3AR) Trp64Arg and peroxisome proliferator activated receptor gamma 2 (PPAR72) Prol2Ala polymorphisms on insulin resistance. Methods One hundred and eight dizygotic twin pairs were enrolled in this study. Microsatellite polymorphism was used to diagnose zygosity of twins. Insulin sensitivity was estimated with logarithm transformed homeostasis model assessment (HOMA). PCR-RFLP analysis was performed to detect the variants. As a supplement to the sib-pair method, identity by state (IBS) was used to analyze the association of polymorphisms with insulin sensitivity. Results The genotype frequencies of Trp64Trg, Trp64Arg, and Arg64Arg were 72.3%, 23.8%, and 3.9%, respectively, while the genotype frequencies of Pro12Pro, Pro12Ala, and Ala12Ala were 89.9%, 9.6%, and 0.5%, respectively. For β3AR Trp64Arg the interclass co-twin correlations of Waist-to-hip ratio (WHR), blood glucose (GLU), and insulin (INS), homeostasis model assessment insulin resistance index (HOMA-IR) of the twin pairs sharing 2 alleles of IBS were greater than those sharing 0-1 allele of IBS, and HOMA4R had statistic significance. For PPAR3t2 Prol2Ala most traits of twin pairs sharing 2 alleles of IBS had greater correlations and statistic significance in body mass index (BMI), WHR, percent of body fat (PBF) and GLU, but there were low correlations of either insulin or HOMA-IR of twin pairs sharing 1 or 2 alleles of IBS. The combined effects of the two variations showed less squared significant twin-pair differences of INS and HOMA-IR among twins sharing 4 alleles of IBS. Condusions β3AR Trp64Arg and PPAR),2 Pro 12Ala polymorphisms might be associated with insulin resistance and obesity, and there might be slight synergistic effects between this two gene loci, and further studies are necessary to confirm this finding. 展开更多

Adrenergic receptor dysfunction is suggested as a potential cause of hippocampal vulnerability to stress-related pathology. We examined mRNA expression of adrenergic receptor (AR) subtypes α1-AR, α1-AR, and β1-AR in hippocampal subregions (CA1, CA3, dentate gyrus) using in situ hybridization in a depression model induced by chronic unpredictable mild stress and social isolation, α1-AR mRNA expression was significantly increased in the CA3 and dentate gyrus, β1-AR mRNA was significantly increased in the CA1, and α1-AR mRNA remained unchanged in all regions of depression rats compared with controls. Thus, different AR subtypes exhibit a differing pattern of mRNA expression in various hippocampal subregions following depression. 展开更多

There was a significant decrease of beta-receptor density in several tissue struc-tures of asthmatic guinea pig lungs compared with the controls, a 23.73% decrease in beta-recep-tor binding sites in bronchiolar smooth muscles and a 18.65% decrease in bronchial smoothmuscles; a 23 .53%. a 14.23% and a 17. 16% decrease in bronchiolar epithelium, in bronchialepithelium and in alveolar epithelium respectively. The results indicated that the beta-recep-tor decrease in smooth muscles in experimental asthmatic guinea pig lungs might be one ofthe important factors which made the tension of smooth muscles increase. The relationshipbetween the beta-receptor decrease of other sites and bronchial asthma needs to be studiedfurther. 展开更多

Dendrite ramification affects synaptic strength and plays a crucial role in memory. Previous studies revealed a correlation between beta 2-adrenergic receptor dysfunction and Alzheimer's disease (AD), although the mechanism involved is still poorly understood. The current study investigated the potential effect of the selective β2-adrenergic receptor antagonist, ICI 118551 (ICI), on Aβ deposits and AD-related cognitive impairment. Morris water maze test results demonstrated that the performance of AD-transgenic (TG) mice treated with ICI (AD-TG/ICI) was significantly poorer compared with NaCl-treated AD-TG mice (AD-TG/NaCl), suggesting that β2-adrenergic receptor blockage by ICI might reduce the learning and memory abilities of mice. Golgi staining and immunohistochemical staining revealed that blockage of the β2-adrenergic receptor by ICI treatment decreased the number of dendritic branches, and ICI treatment in AD-TG mice decreased the expression of hippocampal synaptophysin and synapsin 1. Western blot assay results showed that the blockage of β2-adrener- gic receptor increased amyloid-β accumulation by downregulating hippocampal a-secretase activity and increasing the phosphorylation of amyloid precursor protein. These findings suggest that blocking the β2-adrenergic receptor inhibits dendrite ramification of hippocampal neurons in a mouse model of AD. 展开更多

Objective: The molecular mechanism of prostate cancer is poorly understood. The aim of the study was to investigate the prevalence and prognostic value of promoter hypermethylation of retinoic acid receptor beta (RARB) and p16 among benign prostatic hyperplasia (BPH) and prostate cancer patients. Methods: In this case-control study, 63 patients were included in three groups; 21 with BPH as the control group, 21 with prostate cancer and good prognostic factors (based on prostate-specific antigen, Gleason score and stage) as good prognosis group, and 21 with prostate cancer and poor prognostic features as poor prognosis group. The prostate biopsy specimen of each individual was examined for hypermethylation of RARB and p16 promoters by methylation specific PCR (MSPCR). Results: Seven (33.3%) patients with good prognosis and 15 (71.4%) patients with poor prognosis were positive for RARB methylation, which were significantly higher than controls (P <0.0001). p16 promoter methylation was shown in 19.0% and 47.6% patients with good and poor prognosis, respectively. The RARB and p16 promoter methylation in the poor prognosis group was significantly higher than that in the good prognosis group (P =0.02 for RARB and P<0.0001 for p16). Conclusion: Hypermethylation of RARB and p16 promoters may predict prognosis in prostate cancer. 展开更多
