A evolução do aparelho mastigatório dos primatas do Novo Mundo (16 gêneros correntemente reconhecidos para fauna recente, além de 4 formas fósseis) é abordada através de uma análise cladística. A informação contida neste complexo morfológico foi sintetizada em 80 hipóteses de homologia primária, e reunidas em uma matriz junto a outros atributos biológicos reunidos por HOROVITZ (1990), compreendendo um total de 131 séries de transformação. A matriz de caracteres correspondente a este universo de informações fenotípicas foi submetida a uma análise de parcimônia através da combinação de branch swapping (m* bb*) do programa Hennig86, considerando todos os caracteres como não-ordenados e o fóssil Aegyptopithecus como a referência de enraizamento. Obteve-se como resultado 40 árvores igualmente parcimoniosas de 289 passos, com ci = 0.48 e ri = 0.67. Após esta etapa, a ponderação sucessiva foi implementada, resultando em uma única árvore com 889 passos, ci = 0.72 e ri = 0.85. Este foi considerado o resultado principal deste estudo...
This Thesis studied the evolution of the masticatory apparatus of the New World monkeys as part of a broader cladistic research program on primate evolution. All the 16 currently recognized extant genera currently plus 4 fossil taxa were investigated. The information content in this morphological complex is summarized in 80 hypotheses of primary homology. Additionally, the final matrix also included 25 biological attributes assembled by HOROVITZ (1990), bringing a total of 131 transformation series. The branch swapping algorithm was chosen for the heuristic parsimony analysis (m* bb* - Hennig86 software). All characters were treated as unorder and Aegyptopithecus was used as the rooting reference. The analysis yielded 40 equally parsimonious trees (289 steps, CI = 0.48 and RI = 0.67). Howevre, after using the successive weighting option, the reanalysis os the same data matrix resulted on a single tree (889 steps, CI = 72 and RI= 85) that was considered the major result of the Thesis...

Full textGenes involved in pathogen-host interactions are strongly affected by positive natural selection. The gene of blood Duffy antigen, also known as DARC (Duffy Antigen Receptor for Chemokines), has an important role in the invasion of red blood cells by the parasites that cause malaria, Plasmodium vivax in humans and Plasmodium knowlesi in other primates. The structure of the DARC gene is known, it was mapped in 1q22-q23 region of chromosome 1, and is composed by two exons separated by a large intron. In an African population a nucleic acid deletion in GATA-1 of the gene promoter is responsible for the non-expression of DARC on red blood cells and the resistance to invasion by P. vivax. Moreover, the DARC antigen acts as a promiscuous receptor for chemokines and is expressed in red blood cells, endothelial venules cells and other tissues. Because of this dual role, in this study we sequenced homologous regions of the DARC gene in monkeys of the New and Old World and using statistical methods we tried to detect positive natural selection in their evolutionary history. New mutations were not found at promoter or in coding region. The phylogenetic trees by the methods of maximum parsimony, maximum likelihood and neighbor-join showed similar topologies with three large monophyletic clades recognizable and with the Macaca fascicularis showing a poliphyletic profile. The test of positive selection by the methods of Nei-Gojobori, maximum likelihood by branchs and maximum likelihood by sites not shown, statistically, the action of positive selection on the DARC gene. But the maximum likelihood test using sites divided in domains showed that some regions of the DARC gene are subject to different selective pressures, but also failed to detect the signature of positive selection. The results indicate the presence of darwinian selection on P. vivax binding region, but the maximum likelihood tests used, apparently, do not have enough power to detect its signature. Moreover, the results suggest that P. vivax binding region is under the influence of two opposing selective pressures (positive selection exerted by the parasite and purifying selection exerced by chemokines) that can also explain the non-detection of positive selection.

Full textDuring the past years, many evidences from scientific literature have ascribed several actions over animal behaviour to the nonapeptidic hormone oxytocin (OXT). For a better understanding of this association, it was aimed on this research an assay on molecular evolution of the coding sequence of the oxytocin receptor gene (OXTR) on species from the order Primates, and also the design of an oxytocin gene network and its analysis through several vertebrate lineages. We obtained the partial sequence of cDNA from gene OXTR for nine species of New World monkeys, an unpublished data until present. Blending these informations to the sequence of other primates, available at genomic databases, we compared the coding regions of OXTR: among 12 primate species for exon 3, and 17 species for exon 4. We described 30 non-synonyms changes, distributed along 22 different sites. We found that intracellular domain 4 (IC4) has the lowest conservation rate of the OXTR protein, being responsible for 46,6% (14/30) of the observed variations. Likewise, this domain presented the highest number of moderately radical substitutions, according to chemical criteria (Grantham score). We identified three characteristic sites changes, located besides aminoacids highconserved for its great functional importance. A maximum-likelihood analysis by codon of the OXTR gene sequence on 38 vertebrate species showed that negative selection is the strongest power acting over the OXTR gene, although 10% of the sites are presented as possibly relaxed. Methodologies from systems biology were combined for design of an oxytocin functional network, composed by genes AVP, AVPR1A, AVPR1B, ESR1, FOS, HCRT, OXT, OXTR, PRL, PRLH, PRLR and TRH. Conservation levels from those 12 genes were studied on 36 vertebrate species by comparing the translated protein with its human homologous. Two assembling of genes showed conservation pattern significantly different: a more conserved group, associated to oxytocin (OXT), and a more diverse one, related to prolactin (PRL).

Full textEndogenous retroviruses (ERVs) are remains of ancient viral infection in the germ line cells and subsequent vertical transmission. The K family are integrated only in humans and the Old World monkeys. ERVs play a fundamental role on genome evolution and foster variability. The aim of this work was to investigate their distribution and evolutionary dynamics in primate hosts. We found 55 ERV-K genomes in the human genome, 38 in chimpanzee, 35 in orangutan and 19 in Rhesus monkey. Two main groups were recovered by phylogenetic inference, Group O/N, comprising the newest and the oldest proviruses and, Group I, enclosing those with intermediate integration time. Although the primary integration took place in the ancestral lineage of all primates investigated, their evolutionary dynamic was different among them. I propose that ERV-K dynamics depends on the host demography experienced throughout their evolution. This work also investigated the putative source of proviral transcripts detected in HIV carries and cancer patients. The differential expression found under these conditions suggested a biological role of the ERV-K overexpression. Finally, the results showed that the ERV-K overexpression depends on the integrity of specific promoters in their LTR.

Os genes Periods (Per1-3) são importantes na geração da ritmicidade circadiana. Mutações nestes genes têm fortes efeitos sobre o ritmo circadiano e estão associados com distúrbios de sono em humanos. Dentre estes genes, o Per3 tem uma característica peculiar, a presença de uma repetição em tandem de número variável na região codificadora. Esta repetição em tandem está associada com o cronotipo (matutino / vespertino), com Síndrome da fase atrasada e homeostase do sono. Sabe-se que o tamanho dessas repetições em tandem varia entre espécies diferentes, sendo que cada repetição tem o tamanho de 54 nucleotídeos. No genoma de sagüi (Callithrix jacchus), esta região possui sete repetições, enquanto que em outros primatas, esta mesma região possui diferentes tamanhos e pode variar de três a cinco repetições. A caracterização e anotação do gene Per3 em outros primatas (como em Homo sapiens) já é bem conhecida, entretanto, tem-se a falta de caracterização e anotação completa do gene Period3 em Callithrix jacchus. Dado o cenário e fatores descritos, e considerando o organismo sagüi um primata de interesse para uso como organismo modelo em diversos estudos na área de ritmos biológicos, apresenta-se neste projeto a caracterização completa do gene Per3 em Callithrix jacchus. Nesta caracterização inclui: a definição de regiões de éxons e regiões de íntrons, pesquisa de polimorfismo, análise de neutralidade, identificação e análise de elementos transponíveis e RNA não-codificante, e comparação do comprimento da região de repetição em tandem entre os primatas do novo mundo. O gene Per3 em sagüi tem 74.739 pares de basess e tem uma pontuação de alinhamento de 77, quando alinhada com a seqüência do gene humano, e 97, quando alinhada com a seqüência de sagüi disponível na plataforma da Universidade da Califórnia Santa Cruz. Há três ilhas CpG e 20 sítios de ligação de fatores de transcrição, identificadas por análises in silico, na região promotora deste gene em sagüi. Ainda foram identificadas 115 inserções de elementos transponíveis no gene Per3, sendo os Long interspersed nuclear elements e os Short interspersed nuclear elements as classes dominantes. Sobre RNA não codificantes foram obtidos 102 possíveis candidatos por meio da predição feita via técnicas de bioinformática que usam a abordagem de análise comparativa com outros primatas. Na região da repetição em tandem, foram encontrados cinco polimorfismos de nucleotídeo único e quatro destes são não-sinônimos. Quando esta região de repetição foi examinada para se verificar polimorfismos de comprimento, apenas um sagüi (em oitenta) apresentou heterozigozidade (sete e seis repetições). Nenhuma repetição em tandem foi encontrada em mamíferos não-primatas. Em primatas do novo mundo existem variações no comprimento desta região de repetição que vão de duas a onze repetições. O seqüenciamento e caracterização do gene Per3 em sagüi permitirá a diversos outros futuros estudos comportamentais usando este animal como organismo modelo.
The Periods genes (Per1-3) are important in the generation of circadian rhythms. Mutations in these genes have strong effects on the circadian rhythm and are associated with sleep disorders in humans. Among these genes, Per3 has a special feature, the presence of a variable number in tandem repeat in the coding region. This repeat in tandem is associated with diurnal preference (morning / afternoon), with DSPS and sleep homeostasis. It is known that the length of these repeats in tandem varies among different species; being that the length of each repetition is 54 nucleotides. In the genome of marmosets (Callithrix jacchus), this region has seven repeats, whereas in other primates, this same region has different lengths and can vary from three to five repetitions. The characterization and annotation of Per3 gene in other primates (as in Homo sapiens) is already well known, however, there has been a lack of characterization and annotation of the Period3 in Callithrix jacchus. In this scenario and considering marmoset as a primate of interest for use as a model organism in several studies in the field of biological rhythms, this project presents a complete characterization of Per3 gene in Callithrix jacchus. In this characterization was included: the definition of exons´ and introns´ regions, the search for polymorphism, the analysis of neutrality, the identification and analysis of transposable elements and non-coding RNA, and comparing the length of the variable number in tandem repeat between New World primates. The Per3 in marmoset has 74,739 base pairs and has an alignment score of 77, when aligned with the sequence of the human gene, and 97, when aligned with the sequence of marmoset available on the platform of the University of California Santa Cruz. Three CpG islands and 20 transcription factors binding sites were identified, by in silico analysis, in the promoter region of this gene in the marmoset. Were also identified 115 insertions of transposable elements in Per3 gene, and the long interspersed nuclear elements and short interspersed nuclear elements of the dominant classes. About non-coding RNA, 102 possible candidates were obtained through the prediction via bioinformatics techniques that use the analysis approach of comparison with other primates. In the region of repeat in tandem, were found five single nucleotide polymorphisms and four of these are non-synonymous. When this region of repeat was examined to verify the polymorphism length, only one marmoset (in eighty) showed to be heterozygous (seven and six replicates). No variable number repeat in tandem was found in non-primate mammals. In the new world primates there are variations in the length of this repeat region, ranging from two to eleven repeats. The sequencing and characterization of the gene Per3 in marmoset will allow several other future behavioral studies using this animal as a model organism.

Full textThe search for the genetic repertoire behind behavioral and reproductive features of Primate species has challenged our research group. The principal premise in this kind of study is based on the hypothesis that a phenotypic trait (either physiological, behavioral, etc.) shared by an entire taxonomic group should be determined by a genetic repertoire common to these taxa. Considering the complexity of many of these features, we have expanded our studies for several genes of the OXT - AVP - PRL network, using in silico, in vitro, and in vivo approaches. In the present Thesis, the set of genes for the study was selected by a methodology based on biological ontology, with features like maternal behavior, breastfeeding, and reproductive aspects, such as mating and courtship behavior. This selection resulted in 12 candidate genes for the study: AVP, AVPR1A, AVPR1B, ESR1, FOS, HCRT, OXT, OXTR, PRL, PRLH, PRLR, and TRH. We explored here this gene set of the OXT – AVP – PRL network through data mining, searching for their orthologues in many Primate species and other mammals, as well as through new sequence data from the PRLR and PRLH coding region in a set of New World Monkey (NWM) species. Additionally, sequences from the PRLR coding regions were also obtained in marsupial species. To elucidate evolutionary patterns of the genes of interest, we used the NsSites and Branch Sites tests from PAML package, as well as several classic population tests, for different sample sets. In addition, we predicted the secondary structure of target proteins, using a specific methodology of the PSIPRED program, as well as PONDER-FIT for prediction of intrinsically disordered amino acids. Our in silico results suggest that the genes of the vasopressin receptor family (AVPR1A, AVPR1B, and AVPR2) present a pattern compatible with positive selection in placental mammals. Some of the sites with selection signals have linear motifs (SLiMS) predicted in the AVPR2 receptor, which may have facilitated the emergence of adaptive novelties, as was suggested for the kangaroo rat Dipodomys ordii, which inhabits arid regions. Analyses of the original PRLR coding region data on 17 NWM species revealed several sites present in the long form of the receptor with a high probability of being under positive selection, some of them (positions 507, 532 and 572) being associated with twin births, a characteristic of Callitrichidae species. Additionally, we verified in the Siimiformes branch a linear interaction motif that recognizes SH3 domains (Src Homology 3). The SH3 domains and their ligands were described for hundreds of proteins; they provide a particularly convenient and adaptable medium of specific protein-protein interaction to the cell, which can be of functional importance. This work as a whole contributed to the knowledge of the genetic repertoire connected to the complex network of neuroendocrine mechanisms associated to the emergence of physiological and behavioral adaptive traits in different mammalian clades.

Full textModularity is a characteristic property biological systems exhibit regarding the distribution of interactions between their composing elements; in this context, a module is a subset of elements which interact more among themselves than with other subsets. Regarding morphological systems, such property usually refers to the structure of the linear component of the genotype/phenotype map; however, the genetic, developmental, and functional interactions that produce phenotypes are often best described by non-linear dynamics, and a full appreciation of the complexity of such interactions is necessary for understanding phenotypic variational properties. Furthermore, given methodological advances in the field of morphometrics, one may choose different ways to represent morphological variation, and differences between representations may impact inferences made regarding variational properties. The present dissertation aims at exploring the relationship between morphometric representations and the characterization of variational properties, focusing on the comparative analysis of such properties on a macroevolutionary timeframe; Anthropoid Primates are used as a model lineage, given the availability of a large database of skull measurements. This relationship was evaluated under three different perspectives. First, an estimation of the error rates associated with tests for hypothesis that describe modularity patterns related to three different morphometric representations; such evaluation is also associated with an exploration of a subset of the database used here, considering the dynamical properties of developmental interactions that produce the Anthropoid skull. The results of this chapter imply that one of such representations, Procrustes residuals, fails to capture modularity patterns in this setting, considering its particular mathematical underpinnings. Other two representations, interlandmark distances and local shape variables, produce similar results which are directly associated with developmental dynamics, and the differences they exhibit are consistent with their different properties; error rates for tests over both representations are also acceptable. The next chapter deals with comparing these two representations with respect to these different properties, focusing on estimating allometric relationships over local shape variables and the relationship between such estimates and modularity patterns estimated for interlandmark distances. The results found stress out that modularity patterns observed in interlandmark distances are a consequence of allometry; lineages such as Homo and Gorilla, which exhibit distinct modularity patterns in interlandmark distances are associated with substantial changes in allometric relationships for skull traits. The last chapter explores the phylogenetic structure of changes in phenotypic variational properties across Anthropoid diversification, considering local shape variables alone, since this chapter also aims at reinforcing previous results obtained from interlandmark distances, considering a different type of morphometric representation. This chapter shifts the focus from testing a priori-defined modularity patterns to estimating the uncertainty related to covariance matrix structure decomposed over the Anthropoid phylogeny. The results obtained demonstrate that changes in covariance structure on this lineage are localized in the same skull regions across the entire evolutionary history of Anthropoidea, while other regions maintain stable associations. Thus, when one considers the different properties of morphometric representations carefully, inferences made from such representations regarding variational properties are in fact compatible

Full textHere we examined the mitochondrial (control region and cytb gene) and microsatellites genetic diversity of the New World primate, endemic of Atlantic Forest, Alouatta guariba, in order to uncover its genetic structure and evolutionary history as well as it bearing on its taxonomic status. The mtDNA phylogeny shown a deep divergence between clade A (southern of the Santa Catarina state) and the northern part of the distribution, and the latter diverged in a more central clade B (Rio de Janeiro state) and a northernmost clade C (Espírito Santo state), although a population from São Paulo state present haplotypes from the three clades with 16 of 102 individuals in the clade A, 11 of 16 in the clade B and 14 of 32 in the clade C. The divergence time estimated between A and B/C clades was approximately 750 thousand years ago (kya) and between B and C clades was ~600 kya. Microsatellite data showed a clear isolation between the southern and the central+northern areas, in agreement with the mtDNA results. Therefore, our data consistently refute the hypothesis of a northern subspecies or species separated from a largely distributed central+southern one (A. g. clamitans). However, although the two isolated groups identified here certainly deserve appropriate conservation strategies, the absence of: complete concordance between the mtDNA and microsatellite data, reciprocal monophyly in the mtDNA, and clear cut non-genetic diagnostic characters advice against presently erecting then at subspecies or species status. The Bayesian Skyride plot showed that A. guariba underwent a sudden population expansion started ~50 kya followed by a recent reduction ~7 kya. This expansion was only observed in clade A. This fluctuation in population size may have occurred due to climate changes or to competition with A. caraya due to the high niche overlap of these species.
Nós examinamos a diversidade genética do DNA mitocondrial (região controle e gene citocromo b) e locos de microssatélites do primata do Novo Mundo, endêmico da Mata Atlântica, Alouatta guariba, para descobrir a sua estruturação genética e história evolutiva bem como seu status taxonômico. A filogenia mitocondrial mostra uma profunda divergência entre o clado A (sul de Santa Catarina) e a parte norte da distribuição e um segundo grupo divergente entre o clado B (Rio de Janeiro), mais central, e o clado C(Espírito Santo) mais ao norte, embora a população de São Paulo apresente haplótipos nos três clados com 16 de 102 indivíduos presentes no clado A, 11 de 16 no clado B e 14 de 32 no clado C. O tempo de divergência estimado entre os clados A e B/C foi de aproximadamente 750 mil anos atrás e entre os clados B e C foi de aproximadamente 600 mil anos atrás. Em concordância com os resultados do DNA mitocondrial, os dados de microssatélites mostram um claro isolamento das áreas sul e central+norte. Portanto, nossos dados consistentemente refutam a hipótese de uma subespécie ou espécie ao norte separada da central+sul (A. g. clamitans). Entretanto embora os dois grupos isolados identificados aqui certamente mereçam apropriadas estratégias de conservação, a ausência de: completa concordância entre dos dados de DNA mitocondrial e microssatélites, recíproca monofilia no DNA mitocondrial e claro caracteres não genéticos aconselham contra elevar ao status de espécie ou subespécie. A análise de "Bayesian Skyride plot" mostrou que A. guariba sofreu uma expansão populacional há aproximadamente 50. 000 anos atrás seguida por uma recente redução do tamanho populacional a 7. 500 anos. Esta expansão foi somente observada no clado A. Esta flutuação no tamanho populacional pode ter ocorrido devido a mudanças climáticas ou competição com A. caraya devido a alta sobreposição de nicho destas espécies.
