RESEARCH AND STUDY CENTRE


RESEARCH AND EDUCATION IN BIOMEDICINE FROM GENES TO HUMAN

Molecular and functional genomics group (V. Rovīte lab)

The activities of our emerging research group are aimed to discover molecular markers and mechanisms of human disease development and progression to discover potentially actionable targets to improve diagnostics, prognostics and disease management. The studies conducted by our group are fully exploiting close connection to the Latvian national biobank – Genome Database of Latvian population (LGDB), Genome Centre sequencing unit and connection to largest hospitals and medical institutions that enable us to carry out a full cycle of research from patient-derived sample collection to omics analysis, functional studies and final data interpretation. The main projects in our group are related to the discovery of new molecular markers of tumors and the study of cancer development mechanisms in order to find prognostic factors or improve therapy. Currently, our group is implementing projects in the field of gastrointestinal and brain tumors, and endocrine system tumors, as well as in the research of autoimmune diseases. Currently, our team is developing new next-generation sequencing methods and developing experience in functional studies to be able to implement modern research in the field of translational medicine. In our research, we are the first to have successfully implemented single-cell sequencing and spatial transcriptomics methods in Latvia.
