Research Project

Study of molecular mechanisms of resistance to chemotherapy: importance of tumor microenvironment
In our laboratory we study for several years the molecular basis of resistance to chemotherapeutic drugs using as a model system the human tumor cell line SW613-B3 (colon carcinoma). We have shown that this cell line is resistant to several compounds, including etoposide, doxorubicin, paclitaxel, and 2-metossiestradiolo. The effect of various substances potentially able to inhibit cellular metabolism is currently assessed by analyzing not only the proliferation and cell viability, but also markers of apoptosis and autophagy, two interrelated processes and responsible for the resistance of tumor cells.
Recently, our attention has been focused to substances capable of modulating the intracellular pH and, consequently, to induce cell death in cells intrinsically resistant to external insults. Preliminary studies have shown that cells SW613-B3 are sensitive to substances that inhibit exchangers membrane Na+/H+, causing acidification of the cytoplasm and then allowing to assess the impact of the tumor microenvironment.
It is important, in fact, to focus the purpose of research, not only in the study of the cancer cell per se and of the molecular mechanisms that are triggered in it, but to extend the analysis to the environment surrounding the cell, or soluble factors, signal molecules and extracellular matrices that encouraging interaction with surrounding cells, promoting neoplastic transformation. The tumor environment is in fact first promoter of tumor growth and of the subsequent invasion of the tissue, protects the tumor by the immune system of the host organism, strengthens the chemoresistance and provide for the formation of niches for metastases growth.
The project aims to identify the mechanisms underlying the resistance of tumor cells to chemotherapeutic agents, and pay particular attention to the characteristics of the microenvironment in which cells proliferate and eventually migrate. The use of experimental conditions which mimic the characteristics of the tumor microenvironment could allow to obtain important information about the behavior of cells in vivo.
The study of various parameters involved in the regulation of autophagy and apoptosis, as well as the reciprocal regulation of these two mechanisms will provide important results that will help us understand how cancer cells can escape death induced by drugs commonly used in chemotherapy. The knowledge of the molecular basis of these mechanisms of resistance may, in the near future, allow to design specific strategies that enable it to overcome drug resistance and thus induce the complete regression of tumors which are insensitive to chemotherapy.

The second part of the project, in collaboration with the “Dipartimento di Ingegneria Industriale e dell’Informazione” (Università di Pavia), concern the use of photonic crystals in micromachined silicon such as micro-optical devices used to monitor cellular activity. This study allowed us to demonstrate that miniaturized optical devices in silicon can mimics microincubators to study the growth of cells in three-dimensional environments. The analysis of the devices is carried out with optical fibers useful in order to detect the morphology of cells grown in microincubators (without using markers). This technique will allow us to obtain information about how cells live and what changes occur within them, also as a result of modulations and perturbations induced from the outside. Aspect that turns out to be particularly interesting, especially in oncology, as it is possible to study the effects of a potential chemotherapeutic agent on proliferation, differentiation and cell death.
