|title=Interactions between social/ behavioral factors and [[ADRB2]] genotypes may be associated with health at advanced ages in China.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/24016068
|abstract=Existing literature indicates that [[ADRB2]] gene is associated with health and longevity, but none of previous studies investigated associations of carrying the [[ADRB2]] minor alleles and interactions between [[ADRB2]] genotypes and social/behavioral factors(GxE) with health outcomes at advanced ages. This study intends to fill in this research gap. We conducted an exploratory analysis, using longitudinal survey phenotype/genotype data from 877 oldest-old aged 90 . To estimate association of GxE interactions with health outcome, adjusted for the potential correlation between genotypes and social/behavioral factors and various other potentially confounding factors, we develop and test an innovative three-step procedure which combines logistic regression and structural equation methods. Interaction between regular exercise and carrying rs1042718 minor allele is significantly and positively associated with good cognitive function; interaction between regular exercise and carrying rs1042718 or rs1042719 minor allele is significantly and positively associated with self-reported good health; and interaction between social-leisure activities and carrying rs1042719 minor allele is significantly and positively associated with self-reported good health. Carrying rs1042718 or rs1042719 minor alleles is significantly and negatively associated with negative emotion, but the [[ADRB2]] SNPs are not significantly associated with cognitive function and self-reported health. Our structural equation analysis found that, adjusted for the confounding effects of correlation of the [[ADRB2]] SNPs with negative emotion, interaction between negative emotion and carrying rs1042718 or rs1042719 minor allele is significantly and negatively associated with cognitive function. The positive association of regular exercise and social-leisure activities with cognitive function and self-reported health, and negative association of negative emotion with cognitive function, were much stronger among carriers of rs1042718 or rs1042719 alleles, compared to the non-carriers. The results indicate significant positive associations of interactions between social/behavioral factors and the [[ADRB2]] genotypes with health outcomes of cognitive function and self-reported health, and negative associations of carrying rs1042718 or rs1042719 minor alleles with negative emotion, at advanced ages in China. Our findings are exploratory rather than causal conclusions. This study implies that near-future health promotion programs considering individuals' genetic profiles, with appropriate protection of privacy/confidentiality, would yield increased benefits and reduced costs to the programs and their participants.

|title=[[ADRB2]], brain white matter integrity and cognitive ageing in the Lothian Birth Cohort 1936.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/23229623
|abstract=The non-synonymous mutations arg16gly (rs1042713) and gln27glu (rs1042714) in the adrenergic β-2 receptor gene ([[ADRB2]]) have been associated with cognitive function and brain white matter integrity. The current study aimed to replicate these findings and expand them to a broader range of cognitive and brain phenotypes. The sample used is a community-dwelling group of older people, the Lothian Birth Cohort 1936. They had been assessed cognitively at age 11 years, and undertook further cognitive assessments and brain diffusion MRI tractography in older age. The sample size range for cognitive function variables was N = 686-765, and for neuroimaging variables was N = 488-587. Previously-reported findings with these genetic variants did not replicate in this cohort. Novel, nominally significant associations were observed; notably, the integrity of the left arcuate fasciculus mediated the association between rs1042714 and the Digit Symbol Coding test of information processing speed. No significant associations of cognitive and brain phenotypes with [[ADRB2]] variants survived correction for false discovery rate. Previous findings may therefore have been subject to type 1 error. Further study into links between [[ADRB2]], cognitive function and brain white matter integrity is required.

|title=Common genetic variants of the β2-adrenergic receptor affect its translational efficiency and are associated with human longevity.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/23020224
|abstract=β-adrenoceptors are the common pharmacological targets for the treatment of cardiovascular diseases and asthma. Genetic modifications of β-adrenergic system in engineered mice affect their lifespan. Here, we tested whether genes encoding for key components of the β-adrenergic signaling pathway are associated with human longevity. We performed a 10-year follow-up study of the Chinese longitudinal healthy longevity survey. The Han Chinese population in this study consisted of 963 long-lived and 1028 geography-matched young individuals. Sixteen SNPs from [[ADRB1]], [[ADRB2]], [[ADCY5]], [[ADCY6]], and [[MAPK1]] were selected and genotyped. Two SNPs, rs1042718 (C/A) and rs1042719 (G/C), of [[ADRB2]] in linkage disequilibrium (D' = 1.0; r2 = 0.67) were found to be associated with enhanced longevity in men in two geographically isolated populations. Bonferroni-corrected P-values in a combined analysis were 0.00053-0.010. Men with haplotype A-C showed an increased probability to become centenarians (the frequency of A-C in long-lived and young individuals are 0.332 and 0.250, respectively, OR = 1.49, CI 95% = 1.17-1.88, P = 0.0007), in contrast to those with haplotype C-G (the frequency of C-G in long-lived and young individuals are 0.523 and 0.635, respectively, OR = 0.63, CI 95% = 0.51-0.78, P = 0.000018). The permuted P-values were 0.00005 and 0.0009, respectively. [[ADRB2]] encodes the β2-adrenergic receptor; the haplotype A-C markedly reduced its translational efficiency compared with C-G (P = 0.002) in transfected HEK293 cells. Thus, our data indicate that enhanced production of β2-adrenergic receptors caused by genetic variants is inversely associated with human lifespan.

|title=Beta2-adrenergic receptor gene polymorphisms as systemic determinants of healthy aging in an evolutionary context.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/20399803
|abstract=The Gln(27)Glu polymorphism but not the Arg(16)Gly polymorphism of the beta2-adrenergic receptor ([[ADRB2]]) gene appears to be associated with a broad range of aging-associated phenotypes, including cancers at different sites, myocardial infarction (MI), intermittent claudication (IC), and overall/healthy longevity in the Framingham Heart Study Offspring cohort. The Gln(27)Gln genotype increases risks of cancer, MI and IC, whereas the Glu(27) allele or, equivalently, the Gly(16)Glu(27) haplotype tends to be protective against these diseases. Genetic associations with longevity are of opposite nature at young-old and oldest-old ages highlighting the phenomenon of antagonistic pleiotropy. The mechanism of antagonistic pleiotropy is associated with an evolutionary-driven advantage of carriers of a derived Gln(27) allele at younger ages and their survival disadvantage at older ages as a result of increased risks of cancer, MI and IC. The [[ADRB2]] gene can play an important systemic role in healthy aging in evolutionary context that warrants exploration in other populations.

|title=White matter integrity in the splenium of the corpus callosum is related to successful cognitive aging and partly mediates the protective effect of an ancestral polymorphism in [[ADRB2]].
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/20087642
|abstract=It has recently been reported that the evolutionarily ancestral alleles of two functional polymorphisms in the beta(2)-adrenergic receptor gene ([[ADRB2]]) were related to higher cognitive ability in the 70 year old participants of the Lothian Birth Cohort 1936 (LBC1936). One emerging important factor in cognitive aging is the integrity of white matter tracts in the brain. Here, we used diffusion tensor MRI-based tractography to assess the integrity of eight white matter tracts in a subsample of the LBC1936. Higher integrity of the splenium of the corpus callosum predicted better cognitive ability in old age, even after controlling for IQ at age 11. Also, the ancestral allele of one [[ADRB2]] SNP was associated with both splenium integrity and better cognitive aging. While the effects of the SNP and splenium integrity on cognitive aging were largely independent, there was some evidence for a partial mediation effect of [[ADRB2]] status via splenium integrity.

|title=A Functional polymorphism under positive evolutionary selection in [[ADRB2]] is associated with human intelligence with opposite effects in the young and the elderly.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/18855131
|abstract=Comparative genomics offers a novel approach to unravel the genetic basis of complex traits. We performed a two stage analysis where genes ascertained for enhanced protein evolution in primates are subsequently searched for the presence of non-synonymous coding SNPs in the current human population at amino acid sites that differ between humans and chimpanzee. Positively selected genes among primates are generally presumed to determine phenotypic differences between humans and chimpanzee, such as the enhanced cognitive ability of our species. Amino acid substitutions segregating in humans at positively selected amino acid sites are expected to affect phenotypic differences among humans. Therefore we conducted an association study in two family based cohorts and one population based cohort between cognitive ability and the most likely candidate gene among the five that harbored more than one such polymorphism. The derived, human-specific allele of the beta-2 adrenergic receptor Arg16Gly polymorphism was found to be the increaser allele for performance IQ in the young, family based cohort but the decreaser allele for two different measures of cognition in the large Scottish cohort of unrelated individuals. The polymorphism is known to affect signaling activity and modulation of beta-2 adrenergic signaling has been shown to adjust memory consolidation, a trait related to cognition. The opposite effect of the polymorphism on cognition in the two age classes observed in the different cohorts resembles the effect of [[ADRB2]] on hypertension, which also has been reported to be age dependent. This result illustrates the relevance of comparative genomics to detect genes that are involved in human behavior.

|title=Polymorphism of beta-adrenergic receptors and susceptibility to open-angle glaucoma.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/16785856
|abstract=The human trabecular meshwork and ciliary body, which express beta-adrenergic receptors ([[ADRB1]] and [[ADRB2]]), control aqueous humor dynamics. We investigated associations of ADRB polymorphisms with open-angle glaucoma (OAG), because ADRB gene polymorphisms alter receptor function. We studied 240 Japanese controls and 505 Japanese OAG patients including 211 with primary open-angle glaucoma (POAG), and 294 with normal-tension glaucoma (NTG). Associations of four polymorphisms (Ser49Gly and Arg389Gly in the [[ADRB1]] gene; Arg16Gly and Gln27Glu in the [[ADRB2]] gene) were compared between patients and controls. Age, intraocular pressure (IOP), and visual field defects at diagnosis were examined for associations with polymorphisms. The Arg389Gly polymorphism in the [[ADRB1]] gene showed significantly different allele and genotype frequencies in patients with NTG than in controls (p = 0.004 and 0.006, respectively). Other polymorphisms did not show a significant frequency difference. In POAG patients, carriers of Gly16 in the [[ADRB2]] gene were significantly younger at diagnosis than noncarriers (p<0.001). The IOP at diagnosis was significantly higher in OAG patients carrying 27Glu in the [[ADRB2]] gene than in patients without this allele (p<0.001). Clinical characteristics of OAG patients did not differ significantly in relation to other polymorphisms. Certain polymorphisms of the [[ADRB1]] and [[ADRB2]] genes influence the pathophysiology of OAG in Japanese patients.

|title=Interactive effects of common beta2-adrenoceptor haplotypes and age on susceptibility to hypertension and receptor function.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/16027244
|abstract=Few studies have examined to what extent genetic variants of the beta2-adrenoceptor ([[ADRB2]]) are involved in the development of hypertension with age, although beta2-adrenergic receptor responsiveness declines in older subjects. To investigate this, 10 common single-nucleotide polymorphisms (SNPs) in the promoter and coding regions of the [[ADRB2]] gene were genotyped in an unrelated population consisting of 2 ethnic groups: European American (EA; n=610) and African American (AA; n=420). [[ADRB2]] haplotypes were estimated by expectation maximization (EM) algorithm-based methods. In the general population for EAs and AAs, the variants of the [[ADRB2]] gene, including the individual SNPs and their haplotypes, were not associated with hypertension. However, there was a significant interaction between age and one of the common haplotypes (haplotype 1) in EAs (P=0.01). Haplotype 1 was associated with protection against hypertension in young (< or =50 years of age) but not in old (>50 years of age) EAs (odds ratio, 0.5; 95% confidence interval, 0.27 to 0.91; P=0.02). This age-specific effect was further supported by the observations that young subjects carrying > or =1 copy of haplotype 1 had significantly lower diastolic blood pressure and nearly 2-fold higher [[ADRB2]] binding density than the noncarriers (P<0.05). With aging, their [[ADRB2]] numbers decreased to the level of the noncarriers, along with increased body mass index (7%; P<0.05) and decreased heart rate (7%; P<0.001). Our study suggests that age is an important modifier for the effects of [[ADRB2]] polymorphisms on [[ADRB2]] function and the development of hypertension.
