Development of molecular markers related to cellular resistance after photodynamic therapy in breast carcinomas

Abstract

Breast cancer is an extremely complex disease and clinically heterogeneous, characterized by very different prognoses among patients. The heterogeneity of these tumors is also evidenced by the large number of genes that are related to control of growth, death and differentiation. The main problem of such disorder is the recurrence rate after therapy, where more than half of affected patients suffer recurrence. Several clinical, pathological and molecular techniques have been proposed for predicting the recurrence of this tumor. However, to date, the ability to predict the risk of recurrence in patients with breast cancer is not fully effective in an individual. Recently, photodynamic therapy is an alternative that is being used successfully in the treatment of many solid tumors, may be an alternative for tumor reduction. However, despite the important innovations, the mechanism of cellular resistance and subsequent recurrence is also frequently observed in most tumors undergoing this therapy. Thus, to understand the tumor biology, complementing the classical clinicopathological analysis and thereby ensure a better characterization and treatment of breast tumors, further studies on the effect of the application of PDT are needed Considering these aspects, this project have as objective detected markers or molecular pathways that may be related to cellular resistance and subsequent recurrence of tissues undergoing photodynamic therapy, besides to studying the cellular mechanism of this therapy through the combination of analysis gene expression, protein expression and morphological analysis, thus enabling a better understanding of the effect of the application of PDT and thereby provide a better characterization and treatment of breast tumors.
