To sustain the high proliferative rate, tumor cells have an increased demand for biosynthetic precursors used in the synthesis of macromolecules that will compose the daughter cells. For this, tumors consume a large amount of glucose and glutamine, mainly. The alteration in nutrient metabolism has been related to enzyme filamentation, a process conserved from yeast to mammalian cells, but…
Cancer is a disease that has as main characteristic the continuous cellular proliferation. To support the high proliferative rate, tumor cells have increased demand for biosynthetic precursors used in the synthesis of macromolecules that will make up the daughter cells. For that, tumors consume a lot of glucose and glutamine, mainly. The increase in glutamine consumption, in addition to c…
Molecular mechanisms related to the tumorigenic process are traditionally related to oncogenes and tumor supressors deregulation, which control the signaling pathways responsible for the cell cycle regulation, cell growth, cell proliferation and cell death. On the other hand, new evidences point to an alternative mechanism where the primary role of the oncogenes and tumor supressors are t…
Cell proliferation is a crucial process for the embryogenesis and organism growth, being also essential for the proper function of several adult tissues. Although important for the homeostasis of the organism, its deregulation composes the driving force of tumor development. In the past twenty years the relationship between the processes of signal transduction stimulated by growth factors…

One of the central problems of cell biology is how cells organize biochemical reactions in space and time. Traditionally, studies of this problem have focused on reactions concentrated within membrane compartments and organelles. Recently, however, there has been a growing appreciation that the dynamic partitioning of proteins into novel non-membranous compartments can be used to regulate…
Neoplastic cells share characteristics acquired during tumor development that are essential for Cancer progression. In particular, metabolism reprogramming is of paramount importance to meet the high energy and biosynthetic demand of these cells, in addition to being closely linked to epigenetic remodeling and aggressiveness gain. Recently, it has been discovered that Cancer cells live in…
Breast Cancer is the second most common Cancer in incidence and mortality among females and according to national and international health organizations, this number has increased in recent years. The development of new therapies for the treatment of Cancer is necessary because of this increasing number of cases and the difficulty of effective treatments. Among the molecular mechanisms in…
Lymphocytes and macrophages infiltrated in the tumor microenvironment reflect the biology of the tumor and impact its prognosis. However, these cells are challenged with a hostile microenvironment and, during the process of tumor development, multiple mechanisms of suppression of the immune system come into play, favoring the growth of the tumor and gaining malignancy. In conjunction with…
Cancer cells have increased glycolytic and glutaminolytic pathways and consume glucose and glutamine at accelerated rates. The intensification of the glycolytic pathway, coined as the Warburg Effect, and the glutaminolytic pathway, provide several intermediates for different synthesis routes and are a hallmark of malignant transformation. Glutamine, in addition to providing biosynthetic i…
Breast cancer is the most diagnosed type of cancer in women, with an estimated incidence of approximately 3.2 million cases a year by 2050. The triple-negative subtype (Triple Negative Breast Cancer, TNBC), characterized by low expression / no detection of hormone receptors estrogen (ER), progesterone (PR) and growth factors (Her2) is the most common among young women, whose characteristi…

Our main goal is to understand the role of GLS2 on breast cancer progression. For such, we want to answer the following questions:Do M1 and M2 macrophages influence in vitro metastasis of GLS2 expressing cells? GLS2 has been more often linked to anti-tumorigenic effects, mainly in hepatocarcinomas and gliomas. We found a link between GLS2 expression and diminished breast cancer patient s…
Cancer is a major public health problem in many parts of the world, and is the leading cause of death in developed countries and the second leading cause of death in developing countries. Understanding the mechanisms related to tumor development and progression is essential for the improvement of therapeutic approaches to cancer and mobilizes scientific community worldwide. Different huma…
Tumor cells are exposed to multiple nutrients simultaneously, but it is the intensive consumption of glucose and glutamine, the most abundant amino acid in blood plasma, one of the hallmarks of tumor transformation. The uptake and metabolism of glucose with significant secretion of lactate even in the presence of oxygen, known as aerobic glycolysis or Warburg effect, as well as increased …
