lab 03

Our main research interest is to study genotype-phenotype correlation and to reveal combined modulatory role of different genes in respiratory (COPD, CF, asthma) and cardiovascular (thrombosis, cardiomyopathies) diseases, and solid tumors (pancreatic adenocarcinoma, colorectal cancer, lung carcinoma). Selected genes participate in regulation of hemostasis, inflammatory processes, tissue remodeling, signal pathways, cellular proliferation and protection from oxidative stress. We are also involved in investigation of the role of cystic fibrosis (CFTR) gene mutations and polymorphisms in CFTR related disease (CBAVD, chronic pancreatitis and disseminated bronchiectasis).

In order to decipher molecular mechanisms underlying striated muscle disorders we are exploring structural and regulatory roles of stress sensors Ankrd1 and Ankrd2, which link the elastic I-band region of the sarcomere with transcriptional control in the nucleus. The aim is to identify signaling pathways in which they play a role, their downstream targets, as well as regulators of their expression. We search for Ankrd1 mutations associated with hypertrophic cardiomyopathy and evaluate Ankrd2 status in neuromuscular disorders.

Zebrafish (Daniorerio) animal model system is used in our laboratory for cardiovascular research and genotoxicology testing. Zebrafish offers many advantages such as high genetic and organ system homology to humans, high fecundity, easy genetic manipulation and transparency that enable powerful imaging.

Molecular diagnosis of cystic fibrosis, thrombophilia and α1-antitrypsin deficiency, as well as farmacogenetic testing for individual response to anticoagulant therapy are performed and offered as a service.
