Abstract: The present invention relates to the use of PSGR, a member of the G-protein-coupled olfactory receptor family which is over-expressed in prostate cancer tissue, as a marker suitable for an urine-based diagnostic test for prostate cancer which require only typical prostate manipulation and sample acquisition scenarios avoiding invasive tissue collection.
Abstract: The invention relates to the identification of aprataxin (APTX) expression levels as a marker for the response to topoisomerase I inhibitor-based therapies in patients with cancer and, more particularly, colon cancer. The invention also relates to methods for treating patients with cancer who have low APTX expression levels by means of administering a topoisomerase I inhibitor to said patients.
