Cancer Biomarkers Group (A.Linē lab)
The main focus of our group is the discovery and validation of blood-based biomarkers for the early detection, monitoring and prognosis of cancer. Historically, the first object we were working on was autoantibodies against tumour antigens. We exploited our Cancer Antigen Collection comprising >1800 antigens and antigen microarray technology to evaluate their relevance for detection and prognosis of gastric, thyroid, prostate and breast cancer. Currently, our main research area is the investigation of molecular content, functional role and therapeutic applications of cancer-derived extracellular vesicles (EVs). In parallel, we are working on a project aiming to develop a precision medicine test for molecular profiling of breast cancer that helps to choose the best treatment option for each patient and a personalised liquid biopsy for monitoring the treatment response and early detection of recurrence.
