TY - JOUR. T1 - Localization of multiple pleiotropic genes for lipoprotein metabolism in baboons. AU - Rainwater, David L.. AU - Cox, Laura A.. AU - Rogers, Jeffrey. AU - VandeBerg, John L.. AU - Mahamey, Michae L.C.. PY - 2009/7/1. Y1 - 2009/7/1. N2 - We employed a novel approach to identify the key loci that harbor genes influencing lipoprotein metabolism in approximately 2,000 pedigreed baboons fed various diets differing in levels of fat and cholesterol. In this study, 126 overlapping traits related to both LDL and HDL metabolism were normalized and subjected to genome-wide linkage screening. As was expected, the traits were highly, but not completely, correlated. We exploited the information in these correlated traits by focusing on those genomic regions harboring quantitative trait loci (QTL) for multiple traits, reasoning that the more influential genes would impact a larger number of traits. This study identified five major QTL clusters (each with at least two significant logarithm of ...
A multivariate genome-wide association test is proposed for analyzing data on multivariate quantitative phenotypes collected from related subjects. The proposed method is a two-step approach. The first step models the association between the genotype and marginal phenotype using a linear mixed model. The second step uses the correlation between residuals of the linear mixed model to estimate the null distribution of the Fisher combination test statistic. The simulation results show that the proposed method controls the type I error rate and is more powerful than the marginal tests across different population structures (admixed or non-admixed) and relatedness (related or independent). The statistical analysis on the database of the Study of Addiction: Genetics and Environment (SAGE) demonstrates that applying the multivariate association test may facilitate identification of the pleiotropic genes contributing to the risk for alcohol dependence commonly expressed by four correlated phenotypes.

Pleiotropic traits had been previously recognized in the scientific community but had not been experimented on until Gregor Mendels 1866 pea plant experiment. Mendel recognized that certain pea plant traits (seed coat color, flower color, and axial spots) seemed to be inherited together; however, their correlation to a single gene has never been proven. The term pleiotropie was first coined by Ludwig Plate in his Festschrift, which was published in 1910.[3] He originally defined pleiotropy as occurring when several characteristics are dependent upon ... [inheritance]; these characteristics will then always appear together and may thus appear correlated.[4] This definition is still used today. After Plates definition, Hans Gruneberg was the first to study the mechanisms of pleiotropy.[3] In 1938 Gruneberg published an article dividing pleiotropy into two distinct types: genuine and spurious pleiotropy. Genuine pleiotropy is when two distinct primary products arise from one locus. ...

One PLOS paper details a study of pleiotropy in C. Elegans, finding that 50% of genes involved in embryogenesis are pleiotropic. Whats more, these genes tend to occupy central (rather than initial or final) positions in protein pathways10. Pleiotropy, when viewed in the light of evolution, is usually discussed as a constraining factor. That is, a single mutation may be beneficial or neutral in one tissue, but harmful in another, increasing the likelihood that pleiotropic gene mutations would be selected against. The effect of pleiotropy neednt always be one of constraint, however. For example, in the case of parsimonious pleiotropy11, knowing that a mutation that fails to harm sperm is also unlikely to harm the brain, the sperm may relax strict mutation checking controls a tad. Note that evolutionary pressures favoring pleiotropy tend to negate the popular notion of modularity in gene expression ...

There is growing evidence of shared risk alleles for complex traits (pleiotropy), including autoimmune and neuropsychiatric diseases. This might be due to sharing among all individuals (whole-group pleiotropy) or a subset of individuals in a genetically heterogeneous cohort (subgroup heterogeneity). Here we describe the use of a well-powered statistic, BUHMBOX, to distinguish between those two situations using genotype data. We observed a shared genetic basis for 11 autoimmune diseases and type 1 diabetes (T1D; P , 1 x 10(-4)) and for 11 autoimmune diseases and rheumatoid arthritis (RA; P , 1 x 10(-3)). This sharing was not explained by subgroup heterogeneity (corrected P-BUHMBOX , 0.2; 6,670 T1D cases and 7,279 RA cases). Genetic sharing between seronegative and seropostive RA (P , 1 x 10(-9)) had significant evidence of subgroup heterogeneity, suggesting a subgroup of seropositive-like cases within seronegative cases (P-BUHMBOX = 0.008; 2,406 seronegative RA cases). We also observed a shared ...
Alcohol and other substance use disorders (AUD and SUD) is a complex disease that postulates have a polygenic inheritance and frequent comorbidity with other disorders.

Cave animals have adapted to the challenges of life in perpetual darkness by losing their eyes and pigmentation and enhancing other sensory systems, such as taste, smell, and tactile senses. Although the sensory gains are easily explained by natural selection, the losses are more difficult to explain because they seem to have no immediate benefits. Recent studies in the Mexican cavefish (Astyanax mexicanus) show that eye degeneration is developmentally linked to adaptive gains in the gustatory system via evolutionary changes in a pleiotropic gene called sonic hedgehog. Thus, cavefish may illustrate a general phenomenon in biology in which pleiotropy and indirect selection guide the course and extent of evolution. Another benefit for cavefish living in dark caves is the absence of predators, which promotes survival by evolving an unusual suite of feeding behaviors. These behaviors would be risky in more complex, well-lit environments, such as exist on the Earths surface, illustrating the ...

In the early days of genetics, genes were thought to be solitary entities. Now its well understood that genes operate in complex networks and that gene mutations can have multiple detrimental effects. A new study reconfirms mutations are a major roadblock for evolution.1. Before the advent of modern molecular biology, scientists defined a gene as a single unit of inheritance. If a gene was found to influence multiple externally visible traits, it was said to be pleiotropic-a term first used in 1910.2 During this early period of genetic discovery, pleiotropy was considered to be quite rare because scientists assumed most genes only possessed a single function-a simplistic idea that remained popular throughout most of the 20th century. However, as our understanding of genetics grew through DNA science, it became clear that genes operate in complex interconnected networks. Furthermore, individual genes produce multiple variants of end products with different effects through a variety of intricate ...
It is recognized that the immune system, comprising both innate (nonspecific) and acquired (specific) components, is an intricate defence system that is highly conserved across vertebrate species, and has, from an evolutionary perspective, undergone strong pressures to maximize survival to allow procreation. The significant improvements in human survival and lifespan to well beyond childbearing ages have been totally unpredicted by evolution. As a consequence, human immune systems are exposed to considerable additional antigenic exposure outside the forces of natural selection. It is in this situation that immunity begins to exert negative effects on human ageing (antagonistic pleiotropy), leading to gradual systemic failures. Research into age-related changes of the immune system is gathering pace as its importance within the context of multiple pathologies in ageing populations is realized. As part of this advance, [researchers] described the phenomenon of inflammaging at the turn of the ...

The joint analysis of multiple traits has recently become popular since it can increase statistical power to detect genetic variants and there is increasing evidence showing that pleiotropy is a widespread phenomenon in complex diseases. Currently, most of existing methods use all of the traits for testing the association between multiple traits and a single variant. However, those methods for association studies may lose power in the presence of a large number of noise traits. In this paper, we propose an

Approach and Results-We adapted Egger regression, a technique frequently used in Mendelian randomization studies to detect genetic pleiotropy, to reanalyze the available randomized control trial data of statin therapy. For cardiovascular end points, each 1 mmol/L change in LDL-C with statin therapy was associated with a hazard ratio of 0.77 (95% confidence interval, 0.71-0.84) with an intercept that was indistinguishable from zero (intercept, −0.0032; [95% confidence interval, −0.090 to 0.084]; P=0.94), indicating no pleiotropy. For incident diabetes mellitus, a 1 mmol/L change in LDL-C with statin therapy was associated with a hazard ratio of 1.07 (95% confidence interval, 0.99-1.16) and an intercept nondistinguishable from zero (intercept, −0.015; [95% confidence interval, −0.30 to 0.27]; P=0.91), again indicating no pleiotropy. ...
Pleiotropic genes can influence the course of evolution by producing correlated responses to selection and potentially hindering adaptive evolution if alternative alleles have antagonistic effects on fitness traits.

Infections occur as early as the first year of life and may impact the immune system and cancer risk. The increase in antigenic exposure, after birth through viral/bacterial infections, may be essential for newborns to switch from a Th2 biased [19] to a balanced Th1/Th2 immunity as well as to develop immunological memory [20]. Also, childhood diseases may activate specific anti-tumoral responses. For instance, mumps may lead to immune recognition of TAA present on ovarian cancer cells, resulting in an effective immunosurveillance [21]. However, childhood diseases could be associated with inflammation, and the persistence of this inflammatory process in adulthood may increase the risk of mutations in normal cells, giving an example of antagonistic pleiotropy4. In fact, individuals that have experienced major childhood illness are twice at risk to develop a cancer [22]. Leukemia is a specific example where childhood infections seem to play an ambiguous role [23]. A protective role of infections ...
Scientists in the life science field have long been seeking genetic variants associated with complex diseases (or traits) to advance our understanding of complex genetic disorders and to provide effective disease treatment. However, many complex diseases are driven by the combined effect of many genetic variants, each of which may have only a small effect. To identify these genetic variants, large sample sizes are required but meeting such a requirement is usually beyond the capacity of a single GWAS. Exploring the pleiotropy across multiple related diseases is a promising strategy for identifying genetic variants with small effects, thereby uncovering the mystery of biological mechanisms in complex diseases. In this work we introduce a new approach, latent low rank model (LLR), to leverage pleiotropy across multiple traits to increase power for fine-mapping. LLR uses a latent variable Z to indicate the null and non-null states of loci for each trait. Meanwhile, the prior probability of the ...

Traditional genome-wide scans for positive selection have mainly uncovered selective sweeps associated with monogenic traits. While selection on quantitative traits is much more common, very few signals have been detected because of their polygenic nature. We searched for positive selection signals underlying coronary artery disease (CAD) in worldwide populations, using novel approaches to quantify relationships between polygenic selection signals and CAD genetic risk. We identified new candidate adaptive loci that appear to have been directly modified by disease pressures given their significant associations with CAD genetic risk. These candidates were all uniquely and consistently associated with many different male and female reproductive traits suggesting selection may have also targeted these because of their direct effects on fitness. We found that CAD loci are significantly enriched for lifetime reproductive success relative to the rest of the human genome, with evidence that the ...

The RNAi screen was performed in 96-well plates as described in Fernandez et al. (2010) and Cipriani and Piano (2011). We administered RNAi by feeding, using publically available bacterial RNAi clone libraries (Kamath et al. 2003; Rual et al. 2004). In summary, 0.5 ml of RNAi cultures were grown overnight in 96-well plates, induced for 3 hr using 1 mM IPTG, then pelleted and resuspended in 0.5 mL S medium supplemented with 100 μg/mL ampicillin and 1 mM IPTG. Twenty microliters of each resuspension was dispensed into the equivalent position of each of three new 96-well plates. To collect large quantities of homozygous mel-28 L1 larvae, we used a method called laFACS, in which a FACS machine is used to sort and collect large quantities of live worms of a specific genotype (Fernandez et al. 2010, 2012). Once collected, mel-28 homozygotes from strain PF405 were diluted in S medium + 100 μg/mL ampicillin + 1 mM IPTG to a concentration of 5−10 L1 larvae per 30 μL, then 30 μL of worm resuspension ...
The maternal D-raf serine/threonine kinase acts downstream of Torso (Tor) for specification of cell fates at the embryonic termini. D-raf activity is also required in other signal transduction pathways and consistent with its pleiotropic role, we find accumulation of a 90-kD D-raf protein throughout embryonic development. We also characterize the accumulation of maternal D-raf proteins in 0-2-hr embryos derived from females with germ cells lacking D-raf activity. Accumulation of a 90-kD or truncated mutant D-raf protein is observed for some of these embryos, while others lack the maternal D-raf protein. Then, to determine whether rescue of the Tor pathway is influenced by pools of nonfunctional maternal D-raf, wild-type D-raf mRNA was injected into embryos that inherit maternal stores of inactive 90-kD or truncated D-raf protein. For embryos lacking the maternal D-raf protein, a high level of terminal rescue is obtained. In contrast, rescue is reduced or not observed for embryos that accumulate ...

The revolution in social insect genomics [12-14] now allows rates of evolution and levels of polymorphism to be determined for all loci across multiple genomes. Thus, population genetic predictions arising from kin selection theory can be tested using newly emerging genomic data.. The model presented here makes three predictions. First, antagonistic selection across castes is unlikely to maintain polymorphism. Consequently, loci affecting traits in multiple castes are not expected to show high levels of polymorphism compared with other loci. Overall, this suggests that factors other than caste-antagonistic pleiotropy may be responsible for the maintenance of genetic polymorphism in social species.. Second, the model predicts that the evolution of antagonistic alleles that are favoured in workers, but disfavoured in queens, is impeded by multiple mating by queens. Such worker-beneficial alleles are strong candidates for alleles that would lead to distinct worker phenotypes. Consequently, these ...

Antagonistic selection-where alleles at a locus have opposing effects on male and female fitness (sexual antagonism), or between components of fitness (antagonistic pleiotropy)-might play an important role in maintaining population genetic variation, and in driving phylogenetic and genomic patterns of sexual dimorphism and life-history evolution. While prior theory has thoroughly characterized the conditions necessary for antagonistic balancing selection to operate, we currently know little about the evolutionary interactions between antagonistic selection, recurrent mutation, and genetic drift, which should collectively shape empirical patterns of genetic variation. To fill this void, we developed and analyzed a series of population genetic models that simultaneously incorporate these processes. Our models identify two general properties of antagonistically selected loci. First, antagonistic selection inflates heterozygosity and fitness variance across a broad parameter range-a result that ...

Two independent regions within HNF1B are consistently identified in prostate and ovarian cancer genome-wide association studies (GWAS); their functional roles are unclear. We link prostate cancer (PC) risk SNPs rs11649743 and rs3760511 with elevated HNF1B gene expression and allele-specific epigenetic silencing, and outline a mechanism by which common risk variants could effect functional changes that increase disease risk: functional assays suggest that HNF1B is a pro-differentiation factor that suppresses epithelial-to-mesenchymal transition (EMT) in unmethylated, healthy tissues. This tumor-suppressor activity is lost when HNF1B is silenced by promoter methylation in the progression to PC. Epigenetic inactivation of HNF1B in ovarian cancer also associates with known risk SNPs, with a similar impact on EMT. This represents one of the first comprehensive studies into the pleiotropic role of a GWAS-associated transcription factor across distinct cancer types, and is the first to describe a conserved
In this prospective cohort study, we demonstrated that higher levels of prediagnostic circulating adiponectin were associated with adverse survival among patients with colorectal cancer, with an approximately 2-fold higher risk of colorectal cancer-specific mortality and 1.7-fold higher risk of overall mortality, after adjusting for other potential determinants of mortality, including BMI. These results suggest that plasma adiponectin is likely to be an independent prognostic factor. Further subgroup analyses revealed that participants with metastatic disease appeared to have the greatest increase in risk of colorectal cancer-specific mortality.. The potential pleiotropic roles of adiponectin have generated much controversy. Adiponectin has been demonstrated to possess anticarcinogenic effects via both direct and indirect mechanisms. In vitro studies have shown that activation of the AMPK pathway in cancer cells, with consequent downregulation of mTOR and increased expression of cyclin-dependent ...
The HLA-F adjacent transcript 10 (FAT10) is a member of the ubiquitin-like gene family that alters protein function/stability through covalent ligation. Although FAT10 is induced by inflammatory mediators and implicated in immunity, the physiological functions of FAT10 are poorly defined. We report the discovery that FAT10 regulates lifespan through pleiotropic actions on metabolism and inflammation. Median and overall lifespan are increased 20% in FAT10ko mice, coincident with elevated metabolic rate, preferential use of fat as fuel, and dramatically reduced adiposity. This phenotype is associated with metabolic reprogramming of skeletal muscle (i.e., increased AMP kinase activity, β-oxidation and -uncoupling, and decreased triglyceride content). Moreover, knockout mice have reduced circulating glucose and insulin levels and enhanced insulin sensitivity in metabolic tissues, consistent with elevated IL-10 in skeletal muscle and serum. These observations suggest novel roles of FAT10 in immune ...

Synopsis:. With reference to the report issued by the specialists, the scope of the global Genomics Market was appraised at US$ 17.2 billion in 2019. It is estimated to increase by a CAGR of 7.7% during the period of forecast and touch US$ 31.1 billion by the completion of 2027.. The genome is the hereditary material of a creature. It comprises together the noncoding DNA and genes, along with chloroplast DNA and mitochondrial DNA. The learning of genomes is known as genomics. The genomics industry is attaining grip due to its uses in a number of arenas of study for example intragenomic phenomenon comprising heterosis, epistasis, , pleiotropy and additional interactions amongst alleles and loci contained by the genome. In this age of medicinal and life science modernizations affecting itself such as an unavoidable acceptance for sustainability of manhood, the research of genomic is composed for exponential development due to authoritative hereditary revolutions serving it..

ssion of cytokines - the process is strictly controlled, ie,these factors are usually produced only by activated cells in response to extracellular signals.Typically, this process occurs rapidly at all regulated gene expression levels, depending on the cell type and status of the cells.Thus, the cytokines are fairly large heterogeneous group of water-soluble polypeptide mediators involved in the immune response, inflammatory response, promoting proliferation, cell growth and hematopoiesis.Their impact is carried out at very low (nanomolar or peak) concentrations.Same cytokine can be produced by different cells, and the mediator, generated in one of the cell populations , may affect the function of various cell types.Different cytokines often exhibit the same biological activity.This is due to pleiotropy and multifunctional action of cytokines.. cytokine system has considerable stability thanks to the interchangeability, the duplication of mediators, their diversity, the presence of synergists ...
After construction of RRC, NMC in consultation with CCET would like to operate the constructed RRC in a PPP model where the operator will be selected through the open bidding process. Regarding the construction of RRC, the city has completed the construction of the foundation of the RRC in early March 2021 and it is now working on the completion of overall RRC. As a pilot wards, NMC had proposed to focus on three selected wards (Bazar II, Munnakkaraya and Kadolkale) for conducting a survey and awareness-raising programs. In this regard, CCET has already conducted a survey in pilot wards during July, 2020. Based on the survey results, the awareness program was designed and being conducted in pilot wards with the assistance of Janathakshan in coordination with NMC and CCET. The survey aims to aware and encourages pilot wards to segregate their waste into organics, recyclables, and non-recyclables where they can sell the recyclables to the RRC and handover the organics and non-recyclables to the ...
