1. Evaluation of the Rho-kinase gene expression and polymorphisms in adult patients with acute appendicitis: a differential impact of gender
SUMMARY OBJECTIVE: Acute appendicitis represents one of the most common causes of acute intra-abdominal emergencies worldwide. In this case-control study, we aimed to investigate associations of Rho-kinase gene expression and polymorphisms with acute appendicitis in a Turkish population. We also aimed to study the effects of gender on these parameters. MET

2. Dyslexia risk variant rs600753 is linked with dyslexia-specific differential allelic expression of DYX1C1
Abstract An increasing number of genetic variants involved in dyslexia development were discovered during the last years, yet little is known about the molecular functional mechanisms of these SNPs. In this study we investigated whether dyslexia candidate SNPs have a direct, disease-specific effect on local expression levels of the assumed target gene by usi

3. Prevalence of the rs1801282 single nucleotide polymorphism of the PPARG gene in patients with metabolic syndrome
Objective This study aimed to get the genotypic and allelic frequencies of rs1801282 in 179 volunteer donors and 154 patients with Metabolic syndrome (MetS) in Brasilia, Brazil and also examine the association with anthropometric, biochemical and hemodynamic variables in the latter group. MetS comprises a group of diseases resulting from insulin resistance,

4. Efeito de hipolipemiantes sobre a expressão de genes envolvidos no transporte reverso do colesterol / Statin effects on expression of genes involved in reverse cholesterol transport
The efficacy of statins in reducing the risk of coronary events is not completely explained by their effects in decreasing cholesterol low-density lipoprotein (LDL-C). One of their additional effects may result from the change in concentration of high-density lipoprotein (HDL), recognized as atheroprotective, mainly for the role in reverse cholesterol transp

5. Duffy Genotype and Clinical Manifestations Severity in Sickle Cell Anemia / Genótipo Duffy e Gravidade das Manifestações Clínicas na Anemia Falciforme
INTRODUCTION: Sickle cell anemia (SCA) presents with large clinical variability and previous studies suggest that genetic polymorphisms may act as complications predictors. The Duffy antigen appears to play an important role in the removal of inflammatory chemokines from the circulation, suggesting that Duffy-Negative individuals have lower clearance of cyto

6. A high-throughput data mining of single nucleotide polymorphisms in Coffea species expresed sequence tags suggests differential homeologous gene expression in the allotetrapoloid Coffea arabica.
Polyploidization constitutes a common mode of evolution in flowering plants. This event provides the raw material for the divergence of function in homeologous genes, leading to phenotypic novelty that can contribute to the success of polyploids in nature or their selection for use in agriculture. Mounting evidence underlined the existence of homeologous exp

8. Estudo do padrão de inativação do cromossomo X em tecido extra-embrionário humano / X-chromosome inactivation pattern in human extra-embryonic tissue
Imprinted inactivation of the paternal X chromosome in marsupials is the primordial mechanism of dosage compensation for X-linked genes between females and males in Therians. In Eutherian mammals, X chromosome inactivation (XCI) evolved into a random process in cells from the embryo proper, where either the maternal or paternal X can be inactivated. However,

9. Análise de expressão e splicing alternativo do gene Mdh-1 de Apis mellifera L. (Hymenoptera: Apidae)
Mdh-1 enzyme locus coding for cytoplasmic malate dehydrogenase has three common alleles Mdh-1100 (F), Mdh-180 (M) e Mdh-165 (S) and it has been extensively used as racial marker in populational studies of Apis mellifera. Additional isoforms are detected by electrophoretic analysis during ontogenetic development of A. mellifera, indicating differential expres

10. ABCB1 C1236T, G2677T/A and C3435T polymorphisms in systemic lupus erythematosus patients
P-glycoprotein (Pgp), the ABCB1 gene product, acts as an efflux pump that transports a large variety of substrates and is a mechanism of cell protection against xenobiotics. An increasing number of studies have shown that some ABCB1 polymorphisms may affect Pgp expression and activity, as well as affecting the development and susceptibility to diseases and p

11. Molecular monitoring of patients with chronic myeloid leukemia treated with imatinib mesylate and evaluation of treatment resistance mechanisms: mutation of BCR-ABL and expression of MDR1 and BCRP genes / Acompanhamento molecular de pacientes com leucemia mielóide crônica tratados com mesilato de imatinibe e avaliação dos mecanismos de resistência ao tratamento: mutação do gene BCR-ABL e expressão dos genes MDR1 e BCRP
Chronic myeloid leukemia is characterized by t(9;22) translocation. The chimeric gene BCR-ABL encodes a p210BCRABL protein with constitutive tyrosine kinase activity which is directly related to CML pathogenesis. The imatinib mesylate, a tyrosine kinase inhibitor, is the first-choice treatment for patients in chronic phase but some patients show primary resi
