Abstract

RESUMO: Apresentamos uma revisão dos diferentes aspectos relacionados aos mamíferos artiodáctilos nativos da Bacia do Alto Paraguai (BAP), área que compreende a planície pantaneira e os planaltos adjacentes, representados por duas espécies da família Tayassuidae (Tayassu pecari e Pecari tajacu) e quatro da família Cervidae (Blastocerus dichotomus, Mazama americana, Mazama gouazoubira e Ozotoceros bezoarticus). Embora originalmente estas seis espécies possuíssem ampla distribuição geográfica, atualmente, algumas delas se encontram global ou regionalmente ameaçadas. Diferentemente do que ocorre nas áreas de planalto, em avançado estágio de degradação ambiental, a planície pantaneira ainda mantém populações viáveis destas espécies, sendo um local importante tanto para a sua conservação quanto para a realização de estudos considerando a ampla heterogeneidade ambiental existente. Procuramos compilar e sintetizar as principais informações relacionadas a história natural, taxonomia, morfologia, estrutura populacional, ecologia e conservação destas espécies, priorizando a utilização de dados gerados por estudos conduzidos nas diferentes regiões da BAP. Para fins de comparação, dados levantados em ecorregiões vizinhas também foram considerados. Esperamos que este trabalho contribua para o aumento do conhecimento destas espécies no Brasil e auxilie na formulação de políticas públicas e na implementação de estratégias de conservação de longo prazo dos taiassuídeos e cervídeos neotropicais. ABASTRACT: Abstract: We present a review of the different aspects related to native artiodactyl mammals from the Upper Paraguay Basin (UPB) and Brazilian Pantanal Basin and highlands, represented by two species from the Tayassuidae family (Tayassu pecari and Pecari tajacu) and four from the Cervidae family (Blastocerus dichotomus, Mazama americana, Mazama gouazoubira, and Ozotoceros bezoarticus). Originally these six species had a wide geographic distribution, but currently, some of them are globally or regionally threatened. However, unlike the deforested Pantanal highlands, the Pantanal basin still maintains healthy populations of these species, making it an ideal area for research and their conservation in this dynamic heterogeneous environment. In this review, we compiled and synthesized the main information related to their natural history, morphology, taxonomy, population structure, ecology and conservation. We prioritized data generated by studies conducted in different regions of the UPB. For comparative purposes, we also include data from neighboring ecoregions. We hope that this review contributes information on these Brazilian species and ultimately contributes to public policies that implement conservation strategies for the long-term conservation of native neotropical peccaries and deer.

Abstract

Cerebellar hypoplasia, mild mental retardation, skeletal abnormalities, and ataxia were present in a 40 years old patient with a complex chromosome rearrangement (CCR). Chromosomes 2, 5, 16, and 17 were involved in the CCR. For the definition of the eight breakpoints leading to the rearrangement FISH with whole chromosomes paintings and specific telomeric probes was employed. Gene disruption, positional effect variegation, and sub-microscopic deletions are all possible causes for the abnormal phenotype observed in the patient.

Abstract

DNA undermethylation is a characteristic feature of ICF syndrome and has been implicated in the formation of the juxtacentromeric chromosomal abnormalities of this rare syndrome. We have previously shown that in female ICF patients the inactive X chromosome (Xi) is also undermethylated. This result was unexpected since female ICF patients are not more severely affected than male patients. Here we show that CpG island methylation is abnormal in some ICF patients but in other ICF patients, the difference in methylation pattern between Xi and Xa (active X) is maintained. The consequences of Xi undermethylation on gene expression were investigated by enzyme assays. They showed that significant gene expression did not correlate with CpG island methylation status. The widespread Xi undermethylation does not affect overall Xi replication timing and does not prevent Barr body formation suggesting that a normal methylation pattern is not required for normal chromatin organization of Xi. Molecular investigation of some X-chromosome intron regions showed that the methylation changes in ICF female patients extend to non CpG islands sequences. Our results suggest that the genetic alteration of DNA methylation in ICF syndrome has little consequence on X chromosome gene expression and chromatin organization. [ABSTRACT FROM AUTHOR]

44. Immunodeficiency, centromeric heterochromatin instability of chromosomes 1, 9, and 16, and facial anomalies: the ICF syndrome.

Author

Maraschio, P, Zuffardi, O, Dalla Fior, T, and Tiepolo, L

Abstract

Instability of the heterochromatic centromeric regions of chromosomes 1, 9, and 16 associated with immunodeficiency was found in a four year old girl. Similar phenotypic and chromosomal abnormalities were described in a previous patient studied by us and in four other published cases. All these patients have facial anomalies in addition to combined immunodeficiency and chromosomal instability. Stretching of the heterochromatic centromeric regions of chromosomes 1, 16, and to a lesser extent, 9 and homologous and non-homologous associations of these regions were the most common cytogenetic findings in all the patients. Multi-branched configurations and whole arm deletions of chromosomes 1 or 16 or both were also found. Comparing clinical and chromosomal data we conclude that immunodeficiency, centromeric heterochromatin instability, and facial anomalies form a new syndrome, for which we propose the acronym ICF. A mutation interfering with the normal process of condensation of part of the centromeric heterochromatin is postulated as the basic chromosome defect in this syndrome. [ABSTRACT FROM PUBLISHER]

46. Differential expression of the ICF (immunodeficiency, centromeric heterochromatin, facial anomalies) mutation in lymphocytes and fibroblasts.

Author

Abstract

Fibroblasts from a patient with ICF syndrome were grown in the presence of excess of nucleotides, in media with different amounts of folic acid, and with caffeine in an attempt to induce the chromosomal anomalies observed in lymphocytes. We induced despiralisation and breakages in the centromeric heterochromatin of chromosomes 1 and 16 but not associations and multibranching. We suggest that the absence of the major chromosomal anomalies in fibroblasts from patients with ICF might be the result of both a longer G2 in these cells and differential patterns of interphase heterochromatin associations in the two tissues.
