Core Tip

Core Tip: In colorectal cancer (CRC) cells, we found that parathyroid hormone-related peptide (PTHrP) promotes survival, cell cycle progression, proliferation, migration and chemoresistance and also modulates markers expression associated with invasion, angiogenesis, epithelial to mesenchymal transition and cancer stem cells features. In vivo tests indicate that PTHrP administration increases the expression of several markers related to tumorigenic events. Recently, we observed that PTHrP influences on tumor microenvironment cells, inducing events associated with the progression of CRC. Our project focuses in understanding the biology of CRC and the underlying mechanisms related to the aggressive behavior of CRC cells with the aim to identify new markers that improve the diagnosis, prognosis and therapy of CRC.
