1. Isolation, cultivation and immunofluorescence characterization of lamellar keratinocytes from equine hoof by using explants
RESUMO: É notória a importância do casco na saúde dos equinos, mas o conhecimento em nível celular é pouco entendido. Estudos envolvendo o cultivo de queratinócitos equinos são escassos. Sabe-se que o desenvolvimento de cultivos de queratinócitos in vitro é uma condição para estudos sobre a biologia molecular, crescimento e diferenciação celula

2. Trypanosoma cruzi transcriptome during axenic epimastigote growth curve
BACKGROUND Trypanosoma cruzi is an important protozoan parasite and the causative agent of Chagas disease. A critical step in understanding T. cruzi biology is the study of cellular and molecular features exhibited during its growth curve. OBJECTIVES We aimed to acquire a global view of the gene expression profile of T. cruzi during epimastigote growth.

3. Deferoxamine synergizes with transforming growth factor-β signaling in chondrogenesis
Abstract Osteoarthritis, also known as degenerative arthritis or degenerative joint disease, is an epidemic disease that affects millions of people worldwide. Despite extensive recent work on the cellular biology of osteoarthritis, the precise mechanisms involved are still poorly understood and there is no effective treatment for this disease. The role of tr

4. Molecular biology of human epidermal receptors, signaling pathways and targeted therapy against cancers: new evidences and old challenges
ABSTRACT Human epidermal receptors (HER1/2/3/4) belong to the class of receptor-type tyrosine kinases. After binding a ligand, dimerization, it will ocurr activation of intracellular kinases after two-dimensional and cytoplasmic tail reciprocal transphosphorylation. This transphosphorylation recruits signaling pathways such as Ras/Raf/MEK/Erk1-2, PI3-K/AKT a

5. Avaliação do modelo de hiperargininemia sobre parâmetros neuroquímicos, moleculares e compartamentais em peixe-zebra (Danio rerio): uma abordagem sobre o sistema purinérgico
Hyperargininemia is a rare disease caused by an innate error of the metabolism (EIM) biochemically characterized by the accumulation of arginine in body tissues due to arginase deficits. Mental retardation and other neurological symptoms are common in hyperargininemic patients. Several mechanisms have been proposed to describe the neurotoxicity of hiperargin

6. Recombinant vaccines and the development of new vaccine strategies
Vaccines were initially developed on an empirical basis, relying mostly on attenuation or inactivation of pathogens. Advances in immunology, molecular biology, biochemistry, genomics, and proteomics have added new perspectives to the vaccinology field. The use of recombinant proteins allows the targeting of immune responses focused against few protective ant

7. Identification of significant pathways in gastric cancer based on protein-protein interaction networks and cluster analysis
Gastric cancer is one of the most common and lethal cancers worldwide. However, despite its clinical importance, the regulatory mechanisms involved in the aggressiveness of this cancer are still poorly understood. A better understanding of the biology, genetics and molecular mechanisms of gastric cancer would be useful in developing novel targeted approaches

8. Study of molecular prognostic factors in clear cell renal cell carcinoma by tissue microarray / Estudo de fatores prognósticos moleculares no carcinoma renal de células claras pela técnica de tissue microarray
INTODUCTION: Renal cell carcinoma is an aggressive disease and its incidence is rising. The clear cell variant is the most common, and also the most aggressive. Recent advances in the understanding of the tumors molecular biology indicate that the oncogenesis of each histologic subtype is controlled by distinct cellular mechanisms. Current prognostic models

9. Localização genômica e subcelular dos membros da família de fosfatidilinositol quinases em Trypanosoma cruzi / Genomic and subcellular localization of the members of phosphatidylinositol kinase family in Trypanosoma cruzi
The identification of signaling molecules and the elucidation of signal transduction processes of Trypanosoma cruzi are required for understanding the host-parasite interaction and physiological processes of the parasite. However, little is yet known about signal transduction and signaling pathways that occur in the parasite, since most efforts focused on si

10. 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

12. Receptores A3 da adenosina: uma nova abordagem terapêutica no câncer
Cancer is a multi-factorial disease linked with different initiating causes, cofactors and promoters, and several types of cellular damage. Advancing knowledge on the cellular and molecular biology of the processes that regulate cell proliferation, cell differentiation and cellular responses to external signals, has provided a wealth of information about the
