2. Possible association between a polymorphism of EPAS1 gene and persistent pulmonary hypertension of the newborn: a case-control study
Abstract Objective: To explore possible genes related to the development of persistent pulmonary hypertension of the newborn (PPHN). Methods: The authors identified 285 single nucleotide polymorphisms (SNPs) of 11 candidate genes (BMPR2, EPAS1, PDE3A, VEGFA, ENG, NOTCH3, SOD3, CPS1, ABCA3, ACVRL1, and SMAD9), using an Illumina Asian Screening Array-24 v1.0

3. Hesperidin inhibits the epithelial to mesenchymal transition induced by transforming growth factor-β1 in A549 cells through Smad signaling in the cytoplasm
Hesperidin, a natural compound, suppresses the epithelial-to-mesenchymal transition through the TGF-β1/Smad signaling pathway. However, studies on the detailed effects and mechanisms of hesperidin are rare. The present study showed that, for A549 alveolar epithelial cells, the anti-proliferative effects of hesperidin occurred in a dose-dependent manner, wit

4. The role of KDR in intrauterine adhesions may involve the TGF-β1/Smads signaling pathway
The aim of this study was to investigate the role of kinase-insert domain-containing receptor (KDR) in intrauterine adhesions (IUA) and its mechanism. The Case group consisted of 92 patients diagnosed with IUA, and the Control group included 86 patients with uterine septum who had normal endometrium verified with an uteroscope. In addition, 50 rats were rand

5. Periapical bone response to bacterial lipopolysaccharide is shifted upon cyclooxygenase blockage
Abstract Objectives: Infection, inflammation and bone resorption are closely related events in apical periodontitis development. Therefore, we sought to investigate the role of cyclooxygenase (COX) in osteoclastogenesis and bone metabolism signaling in periapical bone tissue after bacterial lipopolysaccharide (LPS) inoculation into root canals. Methodology

6. Retinoic acid increases the effect of bone morphogenetic protein type 2 on osteogenic differentiation of human adipose-derived stem cells
Abstract Bone morphogenetic protein type 2 (BMP-2) and retinoic acid (RA) are osteoinductive factors that stimulate endogenous mechanisms of bone repair which can be applied on management of osseous defects in oral and maxillofacial fields. Objective Considering the different results of RA on osteogenesis and its possible use to substitute/potency BMP-2 ef

7. Down-Regulation of NFkB, Bax,TGF-β, Smad-2mRNA expression in the Livers of Carbon Tetrachloride Treated Rats using Different Natural Antioxidants
The objective of this study is to examine whether silymarin alone or in combination with chlorogenic acid and/ or melatonin plays a modulatory role against apoptotic damage in rats liver induced by of CCl4. The present work revealed that CCl4 induced elevation of in Bax, Smad, TGF-β and NFkBhepatic mRNA expression, administration of silymarin alone down reg

8. Age-dependent expression of Pten and Smad4 genes in the urogenital system of Wistar rats
PURPOSE: To analyze Pten and Smad4 gene expression in the urogenital system of Wistar rats in differents ages. METHODS: Pten and Smad4 mRNA expression was assessed in the bladder, ventral prostate, testis, ovaries, and uterus by real-time PCR. Statistical analysis using the ANOVA (p<0.05). RESULTS: Pten levels showed a progressive age-dependent increase in

9. Investigação do papel da homeoproteína BARX1 na morfogênese do dente molar em camundongos / Investigation of the role of BARX1 homeoprotein in molar tooth morphogenesis in mice
A dentição não é somente o maior componente do complexo crânio facial dos mamíferos, mas um modelo útil de desenvolvimento, combinado em um sistema de um único órgão, onde ocorrem fenômenos de organização espacial, simetria, aquisição de formas complexas e citodiferenciação órgão-específica. Durante os primeiros estágios do desenvolvimen

10. Addition of bone morphogenetic protein type 2 to ascorbate and β-glycerophosphate supplementation did not enhance osteogenic differentiation of human adipose-derived stem cells
Bone morphogenetic protein type 2 (BMP-2) is a potent local factor, which promotes bone formation and has been used as an osteogenic supplement for mesenchymal stem cells. OBJECTIVES: This study evaluated the effect of a recombinant BMP-2 as well as the endogenous BMP-4 and BMP-7 in the osteogenic differentiation of adipose-derived stem cells (ASCs) in mediu

11. Regulação da via de sinalização de TGF-b pelo microRNA miR- 146b-5p no câncer de tiróide. / Regulation of TGFbeta signaling pathway by microRNA miR-146b-5p in thyroid cancer.
MicroRNAs são pequenos RNAs não codificadores de proteínas envolvidos na regulação pós-transcricional da expressão gênica. Análises de expressão em larga escala identificaram aumento da expressão de miR-146b-5p no carcinoma papilífero (PTC), o subtipo mais prevalente do câncer de tiróide. Uma análise in silico apontou SMAD4, um membro da via d
