1. Revisiting the roles of VHR/DUSP3 phosphatase in human diseases
Protein tyrosine phosphatases have long been considered key regulators of biological processes and are therefore implicated in the origins of various human diseases. Heterozygosity, mutations, deletions, and the complete loss of some of these enzymes have been reported to cause neurodegenerative diseases, autoimmune syndromes, genetic disorders, metabolic di

2. Prevalence of pancreatic autoantibodies in non-diabetic patients with autoimmune thyroid disease and its relation to insulin secretion and glucose tolerance
ABSTRACT Objective We evaluated the prevalence of glutamic acid decarboxylase (GADA) and tyrosine phosphatase-protein antibodies (IA2A), their titers and their relation to first phase insulin response (FPIR) and glucose tolerance in autoimmune thyroid diseases (ATDs) patients. Subjects and methods Graves’ disease (GD; n = 181) and Hashimoto’s thyroid

3. Modelagem molecular proteica dos marcadores genéticos do câncer de tireoide
RESUMO Introdução: Os avanços nos estudos de biologia molecular da tireoide não fornecem apenas uma visão sobre as doenças tireoidianas, mas um diagnóstico preciso do câncer de tireoide. Objetivo: Realizar um tutorial sobre modelagem molecular proteica dos marcadores genéticos do câncer de tireoide. Métodos: As proteínas foram selecionadas uti

4. Beneficial effects of Ginkgo biloba extract on insulin signaling cascade, dyslipidemia, and body adiposity of diet-induced obese rats
Ginkgo biloba extract (GbE) has been indicated as an efficient medicine for the treatment of diabetes mellitus type 2. It remains unclear if its effects are due to an improvement of the insulin signaling cascade, especially in obese subjects. The aim of the present study was to evaluate the effect of GbE on insulin tolerance, food intake, body adiposity, lip

5. PTK2 and PTPN11 expression in myelodysplastic syndromes
OBJECTIVE: The aim of this study was to evaluate the expression of protein tyrosine kinase 2 and protein tyrosine phosphatase non-receptor type 11, which respectively encode focal adhesion kinase protein and src homology 2 domain-containing protein-tyrosine phosphatase 2, in hematopoietic cells from patients with myelodysplastic syndromes. METHODS: Protei

6. Clinicopathological significance of PTPN12 expression in human breast cancer
Protein tyrosine phosphatase non-receptor type 12 (PTPN12) is a recently identified tumor suppressor gene (TSG) that is frequently compromised in human triple-negative breast cancer. In the present study, we investigated the expression of PTPN12 protein by patients with breast cancer in a Chinese population and the relationship between PTPN12 expression leve

7. Trypanosoma rangeli protein tyrosine phosphatase is associated with the parasite's flagellum
Protein tyrosine phosphatases (PTPs) play an essential role in the regulation of cell differentiation in pathogenic trypanosomatids. In this study, we describe a PTP expressed by the non-pathogenic protozoan Trypanosoma rangeli (TrPTP2). The gene for this PTP is orthologous to the T. brucei TbPTP1 and Trypanosoma cruzi (TcPTP2) genes. Cloning and expression

8. 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

9. A transient increase in total head phosphotyrosine levels is observed upon the emergence of Aedes aegypti from the pupal stage
Phosphorylation and dephosphorylation of protein tyrosine residues constitutes a major biochemical regulatory mechanism for the cell. We report a transient increase in the total tyrosine phosphorylation of the Aedes aegypti head during the first days after emergence from the pupal stage. This correlates with an initial reduction in total head protein tyrosin

10. Calix[6]arene, a novel compound acting as a strong inhibitor of the low molecular weight protein tyrosine phosphatase.
Calix[6]arene is a macrocyclic compound of phenolic units linked by methylene group at the 2,6-positions. Besides being used as platform for the development of new drugs and as a carrier of drugs, recently some important pharmacological properties of calixarenes have been reported. The goal of this work was to examine the effect of calix[6]arene on the low m

11. Effect of tyrosine phosphatase Shp2 silencing on phenotypic changes of cardiomycytes and effect of mutations and deletion of Shp2 in the hearts of mjice subjected to mechanical stress / Efeito do silenciamento da tirosino-fosfatase Shp2 nas alterações fenotípicas dos miócitos cardíacos e efeito da deleção e mutações da Shp2 em corações de camundongos submetidos ao estresse mecânico
Estudos do nosso laboratório demonstraram que a quinase de adesão focal (FAK) é ativada e contribui para a regulação dos mecanismos de sinalização que determinam as alterações fenotípicas de cardiomiócitos submetidos a estímulos mecânicos. Em estudo anterior demonstramos através da inibição farmacológica da Shp2, que a mesma contribui para a

12. Caracterização da transmissão do sinal da insulina e da leptina em hipotalamo de roedores durante a anorexia induzida pelo cancer / Characterization of insulin and leptin signaling in the hypothalamus of rodents during cancer induced anorexia
The anorexia-cachexia syndrome is observed in 80% of patients with advanced cancer and contributes directly to increased morbidity and mortality of these patients. It is postulated that the pathogenesis of cancer anorexia is mediated by persistent anorexigenic signs in the hypothalamus, contributing to the reduction of food intake and body weight. In this st
