Research interests
Proteomics is a collective name of several techniques and methods for global/systemic analysis of proteins. Mass spectrometry (MS) based proteomics is an important research field that drives proteome systems biology and generates phenotypic information at the molecular level.
Our Cancer Proteomics Mass Spectrometry group, headed by Professor Janne Lehtiö, is continuously developing mass spectrometry and bioinformatics methods for proteome and systems biology analysis to understand and improve cancer therapy. We develop methods to increased proteome coverage on clinical samples, including increased peptide coverage/protein to study protein variants. This can be illustrated by our developed high resolution isoelectric focusing (HiRIEF) method, which improves the analytical depth in proteomics substantially and allows for search space reduction to enable human proteogenomics. Proteogenomics is an emerging exciting field in MS-based proteomics that combines sample specific information from genomic sequencing, transcriptomics and MS-based proteomics. We use proteogenomics to gain knowledge on how genome changes in cancer influence the proteome level. We have pioneered in developing proteogenomics methods and applied them for cancer proteomics by demonstrating that the method can be used to discover new protein coding loci, such as new gene variants, expressed pseudogenes and long non-coding RNA proteins. This opens up completely new opportunities to develop and improve cancer therapy e.g. immunotherapy.
Our main application focus using proteomics is within the field of breast cancer, lung cancer and leukemia. In summary, we aim to use the proteome information to develop predictive analytical tools and new molecular biomarkers to enable selection of the most effective therapy for each cancer patient.
