Our lab is interested to understand the molecular mechanisms of carcinogensinduced by environmental and dietary exposures (e.g. occupational exposure and chemotherapeutic agents, (e.g. personalized treatment for breast cancer), taking advances of the molecular biology of disease (e.g. cell cycle disturbance by endogenous and exogenous carcinogens, metabolism of carcinogens, DNA repair, andapoptosis) and new methodologies (e.g. Sequencing technologies – the next generation), in order to estimate the accurate role of DNA lesion and genetic susceptibility in Human chronic pathologies.
Carcinogens, DNA lesion damage and repair in aging and cancer: A Toxicogenetics approach.
Aging is a multidimensional process, usually with gradual onset, which results from the effects of genetic and environmental interactions, whose understanding is crucial for unravelling the mechanisms of longevity and aging related diseases. The health of an individual depends upon their DNA as well as upon environment factors (exposome). The exposome represents all toxicants to which people are exposed from both exogenous and endogenous sources and needs to be characterized in order to understand environmental causes of aging and disease.
Since aging is a complex physiological process that poses many problems and conundrums to rapidly aging societies, there is also an urgent need for readily accessible and reproducible biological markers of aging and cancer, by the use of new methodologies/ technologies. These results should be correlated with individual’s genome fingerprint, having as final intention the correlation of this exposome/genome relation with aging and breast cancer.
Familial breast cancer: new biomarkers for an early diagnosis/prognosis
Breast cancer (BC) belongs to the most frequent cancer types in women worldwide. The golden standard method for early diagnosis is still mammography despite its low specificity.
The need for better biomarkers for early BC diagnosis and prognosis is undoubtedly necessary. Knowing the importance of gene environment interactions (GxE) related with cancer, studies of these GxE interactions are needed to obtain better estimates of population-attributable risk(s). The group aims to identify reliable biomarkers of familial breast cancer (FBC) using an exposome top-down study evaluating the internal exposure and early biological effects in a group of women through data on metabolic phenotype, microRNA (miRNA) related with BC, candidate gene variations, oxidative status, DNA repair capacity and susceptibility to FBC.
Additionally, we are also interested in the use of Gold nano-particles, in the development of a more specific and highly sensitive biomolecular diagnostic platform, taking advantage of the high specificity and informative use of microRNAs, using a potential non-invasive methodologies (urine samples) in diagnosis/prognosis of breast cancer.
Breast cancer chemotherapeutic agents: DNA repair polymorphisms, drug response and biomarkers.
Compromised DNA repair is an impetus for carcinogenesis and might promote aggressive clinical behaviour in breast cancer. The different response to chemotherapeutic treatment is subject to wide interindividual variability, which is expressed, not only as differences in severity and type of toxicity, but also as differences in effectiveness. It is well known that several drugs used as breast cancer chemotherapeutic agents have as target the DNA molecule, inducing lesions that lead to neoplasic cell death. However, lesions caused by these agents (generally themselves genotoxic) require complex repair mechanisms.
The heterogeneity of patients’ genetic background allow to establish new strategies which to improve the breast cancer disease outcome to therapy increasing survival rate. In such way, would be relevant emphasize that the understanding of how genetics influence the patients cellular response to drugs, will make it easier to develop personalized therapeutic strategies.
