Project description:Adult cardiac progenitor/stem cells (CPC/CSC) are multipotent resident populations involved in cardiac homeostasis and heart repair. Assisted by complementary RNAseq analysis, we defined the proteome fraction associable to specific CPC functions by comparison with human mesenchymal stem cells (MSC), the reference population for cell therapy. Label-free proteomics analysis identified 526 proteins expressed differentially in CPC. Quantitative iTRAQ analysis confirmed differential expression of a substantial proportion of these proteins expressed specifically in CPC relative to MSC. Systems biology analysis defined a clear overrepresentation of several categories related to enhanced angiogenic potential. The CPC plasma membrane compartment is comprised by 1595 proteins including a minimal signature of 167 proteins expressed preferentially in CPC. Of these core CPC functions, we selected a panel of 15 predicted cell surface markers and validated high differential expression of CDH5, CD200 and F11R in CPC.

Project description:Background: Basal-like breast cancer (BLBC) is a rare aggressive subtype that is less likely to be detected through mammographic screening. Identification of circulating markers associated with BLBC could have promise in detection and management of this deadly disease. Methods: Using samples from the Polish Breast Cancer study, a high-quality population-based case-control study of breast cancer, we screened 10,000 antigens on protein arrays using 45 BLBC patients and 45 controls, and identified 748 promising plasma autoantibodies (AAbs) associated with BLBC. ELISA assays of promising markers were performed on a total of 145 BLBC cases and 145 age-matched controls. Sensitivities at 98% specificity were calculated and a BLBC classifier was constructed. Results: We identified a 13-AAbs (CTAG1B, CTAG2, TP53, RNF216, PPHLN1, PIP4K2C, ZBTB16, TAS2R8, WBP2NL, DOK2, PSRC1, MN1, TRIM21) that distinguished BLBC from controls with 33% sensitivity and 98% specificity. We also discovered a strong association of TP53 AAb with its protein expression (p=0.009) in BLBC patients. Conclusions: These AAbs warrant further investigation in clinical studies to determine their value for further understanding the biology of BLBC and possible detection. The immunoreactivity was compared between 45 BLBC cases and 45 controls against 10,000 human proteins that printed on microscopic slides
