The objective of the Molecular BioMedicine Program is to investigate mechanisms of diseases and develop necessary tools with potential translational outcome in therapy or in medical biotechnology. The program currently focuses on a medically important family of genes associated with regulating mRNA stability and translation which are perturbed as a result of disease. The program has a unique and internationally known research platform which is applicable to the study of several chronic disease conditions including inflammatory, infectious, and cancer states.
- Post-transcriptional control of gene expression: screening of drug-like compounds and modulation in cancer cells
- Post-transcriptional host response to intracellular bacterial pathogens.
- The AU-rich interactome in cancer
- The effect of cytokinome on interferon response
- Interferons and Cytokines
- Disease System Biology
- Translational Biotechnology
