mtDNA structure : the women who formed the Brazilian Northeast
Schaan, Ana Paula; Costa, Lorenna; Santos, Diego; Modesto, Antonio; Amador, Marcos; Lopes, Camile; Rabenhorst, Silvia Helena Barem; Montenegro, RaquelBackground: The distribution of mitochondrial DNA (mtDNA) lineages in Brazil is heterogeneous due to different regional colonization dynamics. Northeastern Brazil, although being an important region in terms of human imigration and ethnic admixture, has little information regarding its population mtDNA composition. Here, we determine which mitochondrial lineages contributed to the formation of the Northeastern ...
Association of IL10 , IL4 , IFNG , and CTLA4 gene polymorphisms with efavirenz ...
Rodrigues, Raphael de Oliveira; Rabenhorst, Silvia Helena Barem; Carvalho, Paulo Germano de; Sasahara, Greyce Luri; Vasconcelos, Luciana Mabel FerreiraSUMMARY: We evaluated interleukin-10 ( IL10 ) － 592 C / A, IL4 － 589 C / T, interferon gamma ( IFNG ) ＋ 874 A / T, cytotoxic T-lymphocyte-associated antigen 4 ( CTLA4 ) ＋ 49 A / G gene polymorphisms associated with efavirenz hypersensitivity reaction. A total of 63 human immunodeficiency virus-positive patients under treatment at a public hospital were included in the study, of whom 21 presented with efavirenz ...
Polymorphism of IL10, IL4, CTLA4, and DAO genes in cross-reactive nonsteroidal ...
Vasconcelos, Luciana Mabel Ferreira; Rodrigues, Raphael de Oliveira; Albuquerque, Andressa Almeida; Barroso, Gabrielle Dantheias; Sasahara, Greyce LuriOur aim was to evaluate genetic polymorphism of molecules involved in immunoregulatory/allergic processes in patients who presented with cutaneous hypersensitivity caused by chemically unrelated nonsteroidal anti-inflammatory drugs. Polymorphisms at IL10 (–1082 G>A), IL4 (–589 C>T), CTLA4 (+49A>G), and DAO (+8956 C>G) genes were studied in 55 cases and 97 controls by the polymerase chain reaction-restriction fr...
Association of the polymorphism in DNA repair enzymes and E-Cadherin gene with ...
Pereira, Eliane dos Santos; Silva-Fernandes, Isabelle Joyce de Lima; Costa, Débora Menezes da; Burbano, Rommel Mario RodriguezSNPs have been associated with gastric cancer susceptibility. Thus, we evaluated the influence of SNPs in DNA repair genes APE1 2197(T>G) and MLH1 -93(G>A), as well as in CDH1 at positions -160 (C>A) and -347 (G>GA) in gastric cancer risk. Analyses were performed on 264 GC patients and 391 healthy controls matched by age and sex from two regions in Brazil, Ceará and Pará. In the general analysis, a protective w...
Characterization of gastric cardia tumors : differences in Helicobacter pylori ...
Costa, Débora Menezes da; Pereira, Eliane dos Santos; Silva- Fernandes, Isabelle Joyce de Lima; Ferreira, Márcia Valéria PitombeiraBackground Gastric cancer results from a multifactorial process and is one of the most common causes of death worldwide. These tumors can arise in the distal stomach (non-cardia) and in the cardia region, presenting different characteristics and frequency of occurrence worldwide. Aims To search for differences between tumors of dif- ferent locations that could explain the presence of cardia tumors, considering ...

Relationship between methylenetetrahydrofolate reductase (C677T), factor V leid...
Freire, Thiago F. V.; Holanda, Gervina B. M.; Costa, Debora M. da; Sampaio, Zuleika S.; Feitosa, Francisco E. L.; Rabenhorst, Silvia Helena BaremObjectives: To better understand the etiologic factors that can influence preeclampsia, we investigated hereditary factors for thrombosis, FV Leiden, F II 20210A mutation and the polymorphism C677T of the MTHFR, as singly and as in association, in a group of women from Ceará state- Northeast Brazil with severe preeclampsia. Material and Methods: We conducted a case-control study. 101 cases of severe preeclampsi...
Association between human papillomavirus (HPV) and the oral squamous cell carci...
Lima, Marcos Antonio Pereira de; Silva, Cláudio Gleidiston Lima da; Rabenhorst, Silvia Helena BaremThe human papillomavirus (HPV) is an epitheliotropic agent whose high-risk genotypes have a well-established link with the development of cervical cancer. Although the relation of HPV to the oral squamous cell carcinoma (OSCC) has been studied since the beginning of the 1980s, its role in the oral carcinogenesis and the probable underlying molecular mechanisms are still not fully elucidated. We performed a syst...
