Full textSe estudiaron los marcadores del DNA mitocondrial (mtDNA) a partir de restricción enzimática de fragmentos en la región codificante y de la secuenciación de un segmento de la región hipervariable I. Los distintos análisis se realizaron observando un estricto control de los criterios de autenticidad en relación a las condiciones de laboratorio, el uso de controles, la caracterización de los investigadores, diversidad genética, sentido filogenético y total correspondencia entre los marcadores mitocondriales, concordancia que es reconocida como un criterio de autenticidad cuando se analiza el mtDNA proveniente de restos antiguos.
De los ciento dos individuos estudiados, ochenta y siete fueron clasificados entre los cuatro principales haplogrupos descritos para nativos americanos (A, B, C y D) y tres no segregaron para ninguno de estos haplogrupos, ni siquiera para el quinto y menos frecuente linaje americano, el haplogrupo X; a la luz de los datos de que se dispone hasta el momento es probable de que se trate de individuos cuyo linaje maternal pertenezca a alguno de los haplogrupos africanos (L1, L2 y L3), siendo la primera evidencia genética del aporte africano en época colonial. En los doce individuos restantes no se lograron amplificaciones positivas para más de un sitio de restricción, por lo cual fueron excluidos de la investigación.
Los análisis de comparación entre las tres series antiguas permiten deducir una continuidad entre los linajes mitocondriales anteriores al contacto europeo y los linajes de la época colonial, no observándose diferencias significativas entre ellas. Sin embargo, la presencia de secuencias únicas en la serie de contacto permite hipotetizar un colapso poblacional en algunos núcleos indígenas. Los resultados obtenidos tanto a nivel de haplogrupos como de secuencias también han sido comparados con datos de poblaciones actuales y antiguas de América y Asia obtenidos de la literatura; y de esta manera, situar en el contexto poblacional americano las muestras antiguas del Valle Central mexicano.
Los procedimientos de reconstrucción filogenética nos permiten deducir que las series antiguas del Valle Central de México tienen un vínculo por vía matrilineal con el resto de las poblaciones americanas, y especialmente con la población mexicana contemporánea de referencia. Además, está virtualmente ausente el aporte europeo en las muestras analizadas, debido posiblemente, a que el proceso de mestizaje que se produjo durante los siglos XVI y XIX fue de tipo unidireccional, hombre europeo-mujer indígena y el mtDNA sólo nos permite el análisis del aporte genético materno.
This paper is a contribution to the genetic diversity study in ancient American populations. DNA from Mesoamerican human skeletal remains from three different periods, which cover from the pre-Hispanic Aztec epoch (late post-classical) to the Viceroyalty of New Spain at the colonial period were analyzed, with the purpose to infer, with the information that the maternal lineages can provide us, Mexico's Central Valley population dynamics; and the possible genetic contribution of the Spanish and African contingents that arrived to the Americas, specifically to Mexico, since the last period of the XVIth century.
Mitochondrial DNA (mtDNA) markers have been studied by both specific restriction enzyme analysis in the coding region and by sequencing of the hypervariable region I segment. The analyses were carried out with a strict control of the authenticity criteria, focusing on: laboratory conditions, use of blank controls, mtDNA characterization of laboratory researchers, genetic diversity, phylogenetic sense and total correspondence among mitochondrial markers, which is recognized as an authenticity criterium where mtDNA analysis from ancient remains is concerned.
Of the hundred two individuals studied, eighty-seven were classified among the four major founding mtDNA haplogroups described for American natives (A, B, C, and D), three individuals didn't segregate for any of these haplogroups, not even for the fifth and less frequent American founding lineage, the haplogroup X; and it is probable that their maternal lineage belong to one of the African haplogroups (L1, L2 or L3), being the first genetic evidence of the African contribution in the colonial epoch. Finally, in twelve individuals positive amplifications were achieved in no more than one restriction site, reason by which they were excluded of the investigation.
The analysis comparison among the three ancient series showed that there is continuity between mitochondrial lineages previous to the European contact and colonial lineages, and that there is not a significant difference among them. Nevertheless, the presence of exclusive lineages in contact series allows us to hypothesize a population collapse in some native groups. The results obtained using both methods of the mtDNA analysis have also been compared with ancient and current populations data from America and Asia available in the literature; and in this way, we have been able to place in the American context the Mexico's Central Valley samples.
Phylogenetic reconstruction procedures permit to deduce that Mexico's Central Valley ancient series have a maternal link with the remaining American populations, and especially with the Mexican current population of reference. In addition the European contribution in the samples analyzed is virtually absent possibly owing to that the mestizaje process that was produced during the XVIth and XIXth centuries was of one-directional: European man - Native woman and mtDNA only permits maternal genetic analysis.

Full textThe zona pellucida is a extracellular matriz that surrounds vertebrate oocytes, and plays important roles in the recognition and interaction of gametes specie- specific, induction of Acrosome Reaction (AR) of the spermatozoa, block to polyspermy, keeps th integrity of the early embryo through its transicion by the oviduct; It is composed of three glycoproteins: ZP3 that induces RA; ZP1, structural, crosslink ZP3 and ZP2. ZP2 acts as a secondary sperm receptor that is necessary for the maintenance of sperm binding to the egg, its proteolytical modification after fertilization permits the block to polyspermy ZP2 participates also in the organization, development, maturation of the oocyte beacuse it keeps consistently the matrix and the interaction between peripherical cells with the germ cell. We isolated and analized in silico a partial coding secquence of the glycoprotein of type 2 (aZP2) in alpacas, we determined that this protein is express exclusively in the ovaries. Also this amalized partial secquence is conserved, constituting a monophyletic group between Cetarteodactyla. This thesis work provides basic knowledge on the glycoprotein a ZP2 in alpacas, a protein implicitly involved in fertilization, to know it benefits the improvement of existing reproductive biotechnology techniques such as the follicular-oocyte maturation, cryopreservation of gametes and embryos in vitro fertilization and injection of intracytoplasmic sperm, techniques that are trying to be implemented with many difficulties in camelids.

Full textTen microsatellites for alpacas and llamas were used to evaluate paternity in 47 alpacas registered at IVITA Research Station Maranganí, Canchis Province (Cusco – Perú). Analysis was carried out using both methodologies: Automatic Sequencer (ABI 377 DNA sequencersâ) and silver staining techniques. Microsatellites were amplified in three multiplex reactions and ten single PCR reactions. They were polymorphic for all alpaca samples using both methodologies. The number of alleles varied between 4 and 20, the allelic frequencies and the exclusion probability were calculated using Cervus 2.0. All loci, except for two, were within the range published by Lang et al. (1996) and Penedo et al. (1998). The accumulated exclusion probability for the ten loci was 0.9999. For each multiplex reaction the accumulated exclusion probability was more than 0.90. Both methodologies yielded the same results. It was possible obtain the same results using both methodologies. The results confirmed paternity in 17 cases of parent-offspring pairs, however in a further 22% of cases alternative adults were identified as parents compared with the register.

Full textEl ADN mitocondrial como marcador genético uniparental ha sido utilizado con éxito para estudiar el poblamiento, historia y orígenes de distintas poblaciones. Es dentro de este contexto, donde el estudio del poblamiento americano, y en particular el continente suramericano cobran vital importancia debido a una serie de eventos que han marcado una heterogeneidad geográfica, cultural, y una estructuración genética que es diferenciada, destacando zonas como los Andes y el Amazonas. Bajo la premisa anterior, el sector del Norte Grande de Chile dentro del contexto sur andino se convierte en un punto válido de interés de estudio, ya que evidencias arqueológicas, etnohistóricas e históricas lo vinculan fuertemente en el área circumpuneña. Desde un punto de vista genético, las investigaciones en materias moleculares en población chilena han usado el ADN mitocondrial como herramienta de estudio para caracterizar mayoritariamente a las poblaciones del centro y sur del país, a diferencia de las poblaciones del Norte Grande. En base al análisis de la región hipervariable del ADN mitocondrial de muestras de saliva de individuos provenientes de las ciudades de Antofagasta y Calama; se registró la predominancia de haplogrupos amerindios y, en particular, una alta proporción del haplogrupo B2, siendo las localidades aledañas a Calama las que muestran una mayor representación de linajes derivados de B2. La ejecución del presente estudio permitió inferir que las ciudades de la costa de la región de Antofagasta se relacionan genéticamente con otras poblaciones nativas del centro y sur del país, mientras que los pueblos aledaños a Calama son cercanos genéticamente a poblaciones nativas del norte de Chile, Noroeste de Argentina (NOA) y Andes bolivianos

Full text--- The use of microsatellites, as molecular markers of human DNA, are important in the studies of affiliation and identification in forensic practices. These studies are based on allelic frequencies in certain populations. For example, in Peru the frequencies reported are often for Hispano-Americans. This research attempts to determine if significant differences among allelic frequencies of the microsatellite D16S539 exist between two populations: a Peruvian Ancash sample and a general sample of Hispano-Americans. Genetic populations studies were carried out in a sample of 33 norelated individuals using PCR followed by 8% polyacrilamide gel electrophoresis and silver staining. The population presented 5 alleles of the 9 found for the D16S539 microsatellite, with the respective frequencies: 9 (0.242), 10 (0.258), 11 (0.288), 12 (0.106) and 13 (0.106). The population in study was found to be in Hardy-Weinberg equilibrium with regard to this marker and there were no significant differences between the allelic frequencies of the population of Ancash origin, and general sample of Hispano-Americans.

Full textIn recent years, several studies have focused on understanding the role of nuclear and, to a lesser extent, mitochondrial genetic determinants, in cardiovascular diseases to prevent clinical events. Although most studies have tried to predict cardiovascular risk using a genetic risk scores based on nuclear variants, so far no risk score was developed using the mitochondrial genome. The main goals of this thesis are summarized in the following three points: 1) to analyse the state of mortality and hospital morbidity from the most relevant cardiovascular diseases in Spain; 2) to determine the possible association of control region variants of the mitochondrial genome with the susceptibility to develop a myocardial infarction and stroke; and 3) to assess whether the incorporation of mitochondrial variants in a genetic risk score, based in nuclear SNPs, improves the ability to discriminate and predict cardiovascular risk. The methods as well as the presentation of the results and the discussion were organized in 4 chapters aimed to answer the defined objectives. In chapter 1, a descriptive epidemiological study that responds to the need to update the mortality and morbidity data of the main subtypes of cardiovascular disease, by age and sex, in all the Spanish autonomous communities over the last 15 years has been carried out. The results obtained show that cardiovascular diseases continue to be one of the main causes of mortality and morbidity in Spain. However, there is also a decrease in standardized mortality rates by age. Bearing this in mind, mitochondrial DNA has been considered for analysis in individuals residing in in the Spanish autonomous community of Castile and Leon who come from cross-sectional, observational and descriptive study. For this reason, in chapter 2 of this thesis the link between mitochondrial haplogroups and two cardiovascular diseases, myocardial infarction and stroke, and the classic cardiovascular risk factors, was investigated. The data obtained showed suggestive evidence that haplogroup H can act as a genetic risk factor for myocardial infarction. Additionally, in relation to classic risk factors, the results also suggested a beneficial role of haplogroup J against hypertension. In chapter 3, for the same Castile and Leon population, the role of fixed and heteroplasmy mutations of the mitochondrial DNA control region, which act as independent risk factors from haplogroups, was analysed. In this case, significant differences were also observed, reporting that the variants m.16.145G> A and m.16.311T> C could act as possible risk factors in the development of stroke, while variants m.72T>C, m.73A>G and m.16.356T>C could act as possible beneficial genetic factors for myocardial infarction. Taking into account the results obtained, a final analysis (chapter 4) was carried out in order to evaluate the magnitude of the mitochondrial genetic information in improving the ability to discriminate cardiovascular diseases. A risk score was created based on the additive model that adds the susceptibility alleles from the 11 nuclear SNPs and the 5 mitochondrial positions described above. The addition of mitochondrial variants improves, in this population, the ability to discriminate cardiovascular diseases beyond the set of classic risk factors and nuclear SNPs. In summary, the results presented in this thesis show the influence of mitochondrial variants on cardiovascular diseases. This is the first work to evaluate the use of a risk score that incorporates the mitochondrial genome and that significantly improves the ability to discriminate cardiovascular events.

Full text-- The Random Amplified Polymorphic DNA (RAPD) is applied on the molecular study of Lama pacos (Alpaca), this methodology is proposed because the microsatellites and DNA mitochondrial techniques, which are used commonly, don't have a practical utility when is necessary to analyze great quantity of samples. Genomic DNA obtained from total blood and primers of 10 nucleotides were used to standardize the RAPD technique following the standardized protocols, and concentration of MgCl2 was modified at 2.5 mM which allowed an increase at the intensity and a better visualization of the bands. After the standardization, the identification of informative primers was realized, beginning with 23 primers, selecting only 7 (OPF 05, OPI 04, OPB 03, OPI 18, OPB 11, OPA 18 and OPI 14), because the presence of several bands for the analyzed samples. These primers let obtain different profiles between hybrid and pure alapacas; in the sample were not found alpacas with a similar bands profiles to those presented by the pure animals, this would explain the hybridization grade that exists due to an inadequate care in the crossing, this results in, for example a low quality in the fiber production from the hybrid alpacas and llamas, diminishing the economic entrance for the rural families. In 8 alpacas the primers OPB-03 and OPA-18 showed polymorphic bands of 650 pb and 1000 pb respectively, this polymorphism could indicate some mutation or intraespecific variability, since these animals don't present evident phenotypic differences.

Full text--- Bostryx scalariformis (Mollusca, Gastropoda) is a land snail species from central Peru. It is endemic to coastal "lomas" ecosystem and inhabits mainly in sand formations. Alive individuals have only been found in Ancon, Pasamayo, Lachay and Cerro de Agua lomas from Lima department. This species has two morphotypes, which in turn are geographically isolated, one morphotype inhabits in Ancon-Pasamayo lomas and the other one in Lachay-Cerro de Agua. Habitat fragmentation and decreasing of population size could have lead to reduction of genetic diversity and to genetic differentiation between its populations. The aim of this research was to evaluate genetic diversity in B. scalariformis comparing it with both its geographical distribution and morphotypes, in order to know about its population genetic structure.
