Antiblastic Drug Resistance (ANDREA)
Antiblastic Drug Resistance (ANDREA)
Treatment failure in cancer is one of the greater problems in the management of human diseases.
The limited efficacy of cancer chemotherapy is due to two main factors:
1. The extremely low therapeutic index of the drugs presently available;
2. The almost invariable occurrence of "innate" or treatment-induced resistance of tumor cells to anticancer drugs.
Antiblastic Drug Resistance (ANDREA)
The aim of the present programme is to attack the problem of anticancer drug resistance through a wide and multidisciplinary research action.
The ultimate goal is to achieve a marked improvement of cancer chemotherapy, thus contributing to realise the objectives of the priority thematic area (1.1.2 – 1.1.2.2).
Antiblastic Drug Resistance (ANDREA)
The strategy of this proposal consists of establishing a network of excellence in which the biomedical, biotechnological and biophysical approaches are integrated in a way that allows a better exploitation of the potentialities of different disciplines such as molecular biology, pharmacology, chemistry optoelectronics, etc.…..
Antiblastic Drug Resistance (ANDREA)
Research will be performed to identify the molecular determinants of chemotherapy with the aim to sensitize tumor cells to the cytotoxic agents of clinical use.
The molecular targets of the biomodulators of
chemoresistance studied will be as follows: proteins that are responsible for drug efflux; proteins involved in drug internalization; DNA repair systems; systems required for modulating the expression of
enzymes involved in the metabolism of cytotoxic drugs; networks involved in cell cycle, apoptosis, as well as
survival in the hypoxic niches occurring in solid tumors.
Antiblastic Drug Resistance (ANDREA)
Pharmacodynamic studies will be performed by Autofluorescence Microspectroscopy (AMS) and Multispectral Imaging Autofluorescence Microscopy (MIAM) techniques, that allow the monitoring of drug intracellular distribution on single living cell.
Ultrasensitive fluorescence techniques for single molecule detection will be applied for studies on molecule diffusion in cell membrane and within the cytoplasm.
Optical tweezers, an optical technique for selective capture and translation of dielectric microparticles, will be applied to study surface interactions.

THEMATIC AREA:THEMATIC AREA:1.1.51.1.5
Diet integrators: therapeutic need, acute and chronic effects, development of suitable analytical tests (DIET)
Life in industrial countries is characterized by high-pressure rhythms and often not enough care is dedicated to the importance of diet.
Nutritionists indicate that incorrect alimentation can cause or increase the risk of many “modern” diseases
Thus, the demand for products improving performance and appearance is increasing exponentially.
Diet integrators: therapeutic need, acute and chronic effects, development of suitable analytical tests. (DIET)
The market offers a wide variety of products to integrate dietary deficiencies and advertising campaigns encourage consumers to use dietary supplements, often without an adequate, expert filter (doctors, nutritionists, etc.).
Moreover, the wide use of diet integrators in zootechnics has great relevance for at least two reasons:
1. the transmission of the substances to the human organisms through the food chain;
2. the development of products for human use on the basis of substances previously utilized for zootechnics.
Diet integrators: therapeutic need, acute and chronic effects, development of suitable analytical tests (DIET)
Products suggested primarily for athletes or subjects performing an intense physical activity are now widely used also by people “not physically stressed”, in order to improve their own fitness and appearance.
At present, we do not have enough information about the risks of a chronic exposure to dietary supplements, assumed both directly and indirectly (through the food chain).
The performed studies have been preferentially directed at a population of sportsmen and mostly concerned acute effects.
A further weak point in the prevention of risks for human health is the scarce quality control performed on these products.
Diet integrators: therapeutic need, acute and chronic effects, development of suitable analytical tests (DIET)
The aim of this programme is to elucidate the real necessity of supplements for “normal” population (if compared to athletes with intense physical activity), to evaluate the efficacy of the treatments, to investigate and monitor acute and long-term effects of integrator intake.
Besides, part of the program will be devoted to develop new detection methods as well as new toxicity tests in vitro (alternative to animals), utilizing suitable experimental models as cell and tissue cultures.

To study the mechanisms of action at the cellular level.

Diet integrators: therapeutic need, acute and chronic effects, development of suitable analytical tests (DIET)
The ultimate goal is to achieve a marked improvement in the knowledge of the complex interaction between integrators intake and metabolism, genetic background, environmental and behavioural factors to identify key risk factors as well as beneficial effects.
