1. From yeast to humans: Understanding the biology of DNA Damage Response (DDR) kinases
Abstract The DNA Damage Response (DDR) is a complex network of biological processes that protect cells from accumulating aberrant DNA structures, thereby maintaining genomic stability and, as a consequence, preventing the development of cancer and other diseases. The DDR pathway is coordinated by a signaling cascade mediated by the PI3K-like kinases (PIKK) A

2. 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

3. 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.

4. 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

5. 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

6. Auxinic herbicides, mechanisms of action, and weed resistance: A look into recent plant science advances
Auxin governs dynamic cellular processes involved at several stages of plant growth and development. In this review, we discuss the mechanisms employed by auxin in light of recent scientific advances, with a focus on synthetic auxins as herbicides and synthetic auxin resistance mechanisms. Two auxin receptors were reported. The plasma membrane receptor ABP1

7. Neuropeptide Y, substance P, and human bone morphogenetic protein 2 stimulate human osteoblast osteogenic activity by enhancing gap junction intercellular communication
Bone homeostasis seems to be controlled by delicate and subtle “cross talk” between the nervous system and “osteo-neuromediators” that control bone remodeling. The purpose of this study was to evaluate the effect of interactions between neuropeptides and human bone morphogenetic protein 2 (hBMP2) on human osteoblasts. We also investigated the effects

8. Study of Vaccinia and Cowpox viruses' replication in Rac1-N17 dominant-negative cells
Interfering with cellular signal transduction pathways is a common strategy used by many viruses to create a propitious intracellular environment for an efficient replication. Our group has been studying cellular signalling pathways activated by the orthopoxviruses Vaccinia (VACV) and Cowpox (CPXV) and their significance to viral replication. In the present

9. Protein profile of rice (Oryza sativa) seeds
Seeds are the most important plant storage organ and play a central role in the life cycle of plants. Since little is known about the protein composition of rice (Oryza sativa) seeds, in this work we used proteomic methods to obtain a reference map of rice seed proteins and identify important molecules. Overall, 480 reproducible protein spots were detected b

10. 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

11. 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

12. 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
