Stomach cancer is fifth in incidence and third in mortality worldwide. The leading cause of gastric carcinogenesis is infection with Helicobater pylori, a bacterium which infects almost half the human population. Differences in virulence strains, other environmental factors and patient (genetic) characteristics contribute to cancer progression among those individuals infected with H pylor…
Over the past decade, the groups led by Prof. Carmen Veríssima Ferreira and Prof. Maikel Peppelenbosch have explored signal transduction pathways in order to define the action mechanisms of antitumor candidates and for identifyng molecular targets related with the aggressiveness and resistance of tumor cells. In this context, we have investigated cell lines and biopsies of patients with p…
The progress of knowledge about the molecular basis of cancer, has reinforced the concept of this multifactorial disease. The challenge in the coming years is to develop strategies to understand the molecular framework of tumor cells, therapeutic approaches to establish "smart" and personalized therapy in order to increase efficiency, specificity and quality of life of patients. In this c…
Melanomas are extremely aggressive tumors that originate from mutations in melanocytes. The high metastatic potential of melanomas is the main obstacle to treatment efficacy. Recently, several studies have increasingly pointed to the relevant role played by the microenvironment in various processes associated with tumor development and progression. Among the components of the tumor microe…
Melanoma is the most lethal type of skin cancer due to its high proliferative rate and capacity for metastasis. Additionally, this tumor displays low response to treatment, which in part is due to a high basal rate of autophagic flow. Therefore, the study of these cellular mechanisms and for the screening of compounds, the 3D culture models have been shown to be effective, as it allows gr…
Colorectal cancer is still top 3 in the cause of cancer death worldwide. The late diagnosis together with the resistance acquisition of this cancer, are responsible for the low efficiency of the therapeutic protocols available. Thus, more effective therapeutic strategies are desirable. To this end, the molecular knowledge of cancer biology and the use of cellular models with a complexity …
About 15-20% of colorectal cancer cases progress to metastasis in other organs reducing the efficiency of current therapy regimens and reducing patient survival. In recent years, research groups have focused on the study of the contribution of Extracellular Vesicles (EVs) in the tumor process. EVs are no longer understood as reservoirs for unwanted proteins and have now been considered as…
Tumor cells must assemble cellular components necessary for the synthesis of macromolecules (nucleotides, proteins, lipids) and much energy to double their genome and enlarge their biomass. To that end, tumors alter cellular metabolism to contribute to tumorigenesis and malignancy. The metabolic characteristics and pathways through which tumor cells acquire and replenish their metabolic n…

The success of cancer prevention and treatment involves efficiency diagnosis and therapy. Over the past years, the Prof. Ferreira-Halder and Prof. Peppelenbosch research groups have investigated cancer cells metabolism to clarify resistance and aggressiveness processes. It was found a correlation between resistance/aggressiveness in leukemia, prostate and colorectal cancer (CRC) and high …
