Abstract

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 expression of Low Weight Molecular Protein Tyrosine Phosphatase (LMWPTP). This proposal will address two important points in cancer field: validation of a newbiomarker (LMWPTP and/or molecules related to LMWPTP) and biological characterization of a small molecule (3-bromopyruvate) that has a potential to re-educate platelets and consequently, inhibits the first step ofhematogenous dissemination of CRC cells. Therefore, the aims will cover: 1) for diagnosis: identify LMWPTP ormiRNAs modulated by this enzyme in fecal samples from patients and used it as a biomarker. Since, the mostused diagnostic testing for colorectal cancer has low sensitivity (fecal occult blood testing), or it is expensive andinvasiveness (colonoscopy), new biomarker that overcomes these problems is urgently needed; and 2) fordecreasing metastasis efficiency: 3-bromopyruvate is able to decrease the interaction between CRC cellsplatelets.This finding indicates that this small molecule has a greater potential to block the metastasis. At this stage, we will scrutinize the molecular mechanism by which it occurs. (AU)
