1. Utilização farmacológica de um composto inédito derivado de quinazolina como inibidor potencial da quinase de adesão focal (FAK) no processo de hipertrofia cardíaca em camundongo = : Pharmacological use of a novel compound quinazoline derivative as potential inhibitor of the focal adhesion kinase in the process of cardiac hypertrophy in mice / Pharmacological use of a novel compound quinazoline derivative as potential inhibitor of the focal adhesion kinase in the process of cardiac hypertrophy in mice
Nas doenças do coração ocorre hipertrofia e remodelamento do ventrículo esquerdo com impacto negativo na evolução clínica. Esses fatores influenciam independentemente o risco cardiovascular por elevarem a predisposição a infartos do miocárdio, ao desenvolvimento de insuficiência cardíaca e ao aparecimento de arritmias ventriculares graves. Estrut

2. Vias de sobrevivência e morte em queratinócitos submetidos ao estresse oxidativo e choque hiperosmótico / Survival and death signaling pathways in keratinocytes exposed to oxidative stress and hyperosmotic shock
The epidermis is constantly confronted with multiple environmental stressors. Changes in humidity or exposition to UV radiation affect the redox state and osmotic balance, modifying the physiological characteristics of the skin. In response to different stresses, epidermal keratinocytes can activate distinct signaling pathways and the balance between death a

3. Vias de sinalização intracelular envolvidas no efeito proliferativo de relaxina em células de sertoli / Intracelular signaling pathways involved in the proliferative effect of relaxin in rat Sertoli cells
Relaxin is an insulin-related peptide that activates the G-protein coupled receptor RXFP1. Although relaxin plays an important role in female reproduction its physiological role in the male reproductive system is still unclear. We have previously demonstrated that relaxin and RXFP1 are expressed in testis (FILONZI et al., 2007; CARDOSO et al., 2010). Both re

4. Angiotensin II induces NF-κB, JNK and p38 MAPK activation in monocytic cells and increases matrix metalloproteinase-9 expression in a PKC- andRho kinase-dependent manner
Angiotensin II (ANG II), the main effector of the renin-angiotensin system, is implicated in endothelial permeability, recruitment and activation of the immune cells, and also vascular remodeling through induction of inflammatory genes. Matrix metalloproteinases (MMPs) are considered to be important inflammatory factors. Elucidation of ANG II signaling pathw

5. FGF2 species of 18 and 22.5 kDa: paracrine molecular signaling and biological functions / FGF2 de 18kDa e de 22,5kDa: sinalização molecular parácrina e funções biológias
FGF2 (Fibroblast Growth Factor 2), the founder of the FGF family, has regulatory functions in mitogenesis, differentiation, morphogenesis and tissue repair. Multiple FGF2 molecular species, sharing a C-terminal sequence of 155 amino acids, are translated from different iniciation sites of the same mRNA. The smaller, the FGF2-18kD, is extracellularly released

6. Proteínas quinases: características estruturais e inibidores químicos
Protein kinases are one of the largest protein families and they are responsible for regulation of a great number of signal transduction pathways in cells, through the phosphorylation of serine, threonine, or tyrosine residues. Deregulation of these enzymes is associated with several diseases including cancer, diabetes and inflammation. For this reason, spec

7. 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

8. Study of the BTK (Brutons Tyrosine Kinase) in patients with congenital agammaglobulinemia. / Estudo do gene btk (brutons tyrosine quinase) em pacientes com agamaglobulinemia congênita
X-linked Agammaglobulinemia (XLA) is a primary immunodeficiency characterized by the absence or decreased numbers of mature B cells in peripheral blood, and by a lack of all immunoglobulin isotypes, leading to an increased susceptibility to severe bacterial and enteroviral infections. XLA is caused by mutations in the gene encoding for Brutons tyrosine kinas

9. Natural compounds as modulators of transduction pathways in tumor cells / Copostos naturais como moduladores de vias de transdução de sinal em celulas tumorais
The search for compounds that specifically act on tumors, with low side effects, is a great aim in the studies related to cancer treatment. Many natural compounds isolated from plants have presented promising results as modulating agents of the signal transduction pathways in several types of tumors. Flavonoids, polyphenolic compounds largely distributed in

10. Mecanismos de transdução de sinal envolvidos com a diferenciação de osteoblastos e osteocitos / Signal transduction activated during differentiation of osteoblsts and osteocytes
The main goal of this work was to investigate the signal transduction pathways triggered during the bone cells differentiation. In this way, several molecular aspects of this process were analyzed. Src kinase modulation by the low molecular weight protein tyrosine phosphatase (LMWPTP) was essential for the occurrence of the differentiation induced by ascorbi

11. Serum amyloid A: biological effects on mononuclear cells / Amilóide sérica A: efeitos biológicos sobre células mononucleares
In the past few years, our research group has described various effects of serum amyloid A (SAA) on cells of the immune system regarding the expression and release of pro-inflammatory cytokines. In this study we have focused on the effects of SAA on mononuclear cells. In order to do this, we have used three experimental models. In the murine experimental mod
