1. A rare case of deafness and renal abnormalities in HDR syndrome caused by a de novo mutation in the GATA3 gene
Abstract HDR syndrome is a rare autosomal dominant disorder caused by mutations in the GATA3 gene and characterized by hypoparathyroidism, sensorineural deafness and renal abnormalities. Here we report a Brazilian family, from which the proband, his mother and his grandfather were diagnosed with bilateral sensorineural hearing loss. Molecular screening of th

2. Single-cell qPCR facilitates the optimization of hematopoietic differentiation in hPSCs/OP9 coculture system
Human pluripotent stem cells (hPSCs)/OP9 coculture system is a widely used hematopoietic differentiation approach. The limited understanding of this process leads to its low efficiency. Thus, we used single-cell qPCR to reveal the gene expression profiles of individual CD34+ cells from different stages of differentiation. According to the dynamic gene expres

3. Intramyocardial implantation of differentiated rat bone marrow mesenchymal stem cells enhanced by TGF-β1 improves cardiac function in heart failure rats
The present study tested the hypotheses that i) transforming growth factor beta 1 (TGF-β1) enhances differentiation of rat bone marrow mesenchymal stem cells (MSCs) towards the cardiomyogenic phenotype and ii) intramyocardial implantation of the TGF-β1-treated MSCs improves cardiac function in heart failure rats. MSCs were treated with different concentrat

4. The epigenetic modifiers 5-aza-2'-deoxycytidine and trichostatin A influence adipocyte differentiation in human mesenchymal stem cells
Epigenetic mechanisms such as DNA methylation and histone modification are important in stem cell differentiation. Methylation is principally associated with transcriptional repression, and histone acetylation is correlated with an active chromatin state. We determined the effects of these epigenetic mechanisms on adipocyte differentiation in mesenchymal ste

5. Novel GATA5 loss-of-function mutations underlie familial atrial fibrillation
OBJECTIVE: This study aimed to identify novel GATA5 mutations that underlie familial atrial fibrillation. METHODS: A total of 110 unrelated patients with familial atrial fibrillation and 200 unrelated, ethnically matched healthy controls were recruited. The entire coding region of the GATA5 gene was sequenced in 110 atrial fibrillation probands. The availabl

6. Embryonic stem-like cells derived from in vitro produced bovine blastocysts
The aim of this work was to study the derivation of bovine embryonic stem-like (ES-like) cells from the inner cell mass (ICM) of in vitro produced blastocysts. The ICMs were mechanically isolated and six out of seventeen (35%) ICMs could attach to a monolayer of murine embryonic fibroblasts (MEF). Ten days after, primary outgrowths were mechanically dissecte

7. Genetic polymorphisms of Rh, Kell, Duffy and Kidd systems in a population from the State of Paraná, southern Brazil
BACKGROUND: Red blood group genes are highly polymorphic and the distribution of alleles varies among different populations and ethnic groups. AIM: To evaluate allele polymorphisms of the Rh, Kell, Duffy and Kidd blood group systems in a population of the State of Paraná METHODS: Rh, Kell, Duffy and Kidd blood group polymorphisms were evaluated in 400 unrel

8. Novel mutations in the TBX5 gene in patients with Holt-Oram Syndrome
The Holt-Oram syndrome (HOS) is an autosomal dominant condition characterized by upper limb and cardiac malformations. Mutations in the TBX5 gene cause HOS and have also been associated with isolated heart and arm defects. Interactions between the TBX5, GATA4 and NKX2.5 proteins have been reported in humans. We screened the TBX5, GATA4, and NKX2.5 genes for

9. Expressão diferencial de genes em células foliculares de suínos
O objetivo neste trabalho foi identificar genes candidatos relacionados à ovulação em suínos. Para tanto, investigou-se a expressão diferencial dos genes STAR (steroidogenic acute regulator), GATA (GATA-binding protein 4), PGF2α (prostaglandin F2α), P4R (progesterone receptor), FSHR (follicle-stimulating hormone receptor) e CYP19 (cytochrome P450 arom

10. Análise do perfil de expressão de fatores de transcrição e miRNAs em reticulócitos de pacientes com talassemia beta intermediária e anemia falciforme / Expression of micoRNAs and transcription factors in reticulocytes from beta thalassemia intermedia and sickle cell disease patientes
As variantes de hemoglobina e as Talassemias estão entre as hemoglobinopatias hereditárias mais frequentes no Brasil. A hemoglobina S é resultante de uma mutação de ponto no gene que codifica a cadeia beta da globina e que em homozigose caracteriza a Anemia Falciforme. Outras variantes neste gene podem ocasionar redução parcial ou completa da síntese

11. Frequência alélica de 14 locos do cromossomo X de indivíduos da região Sul do Brasil
Dois sistemas para amplificação simultânea de short tandem repeats (STRs) do cromossomo X foram desenvolvidos neste trabalho. O Multiplex 1 foi composto por HPRTB, DXS101, DXS7424, DXS6807, DXS6800 e GATA172D05 e o Multiplex 2 foi composto por DXS8378, DXS7133, DXS9898, DXS7423, DXS6809, DXS6789, DXS8377 e DXS6801. Além do desenvolvimento de dois sistema

12. Hsp60 e imunorregulação: estratégias para identificação de peptídeos imunorreguladores / Hsp60 and immunorregulation: strategies for the identification of immunoregulatory peptides
As proteínas de choque térmico (Hsp) apresentam importantes funções homeostáticas e podem induzir respostas imunológicas tanto inflamatórias como reguladoras. Por essas propriedades, as Hsp e seus peptídeos têm grande potencial como agentes imunomoduladores. Neste estudo, o nosso objetivo foi identificar peptídeos da Hsp60 com potencial imunorregul
