Project description:Through digital rectal examinations and routine prostate-specific antigen (PSA) screening, early treatment of prostate cancer has become possible. However, prostate cancer is a complex and heterogeneous disease. In many patients, cancer cells can invade adjacent tissues and metastasize to other tissues, resulting in difficultly to cure. For the treatment of primary and metastatic prostate cancer, a significant problem is how to improve its survival time. Here, we collect 7 untreated primary and metastatic prostate cancer and 6 benign prostate hyperplasia samples under ultrasound guidance by experienced radiologists using the 18-G needle. Through mass spectrometry, we have completely depicted the protein atlas of primary and metastatic prostate cancer and benign prostate hyperplasia. Through bioinformatics analysis, experimental verification, and combined clinical data, we discover that the ribosome signaling pathway promotes the progression of prostate cancer and is associated with a poor prognosis. Among them, Mrpl1, Mrpl4, and Mrpl16 may be biomolecular markers for diagnosis and prognosis.
