Abstract Tumor cells mirrored the high proliferative capacity and phenotypic plasticity of stem cells. The stem cell-like phenotype of various cancer subtypes is directly correlated with increased aggressiveness, resistance to therapies, and worst overall prognosis. However, it is unclear if different subtypes of late-stage cancer vary in stemness properties and whether or not these subtypes are molecularly similar to normal stem cells. Recent molecular characterization studies have benefited from the availability of the datasets generated by The Cancer Genome Atlas (TCGA) enabling more precise molecular-based classification of tumors and relating molecular signatures with prognosis. Notably, DNA methylation has been shown to play important contribution to tumor biology and classification. In this scientific proposal, by using DNA methylation data from 10,000 samples available at TCGA, across 33 different types of tumors, we aim to identify tumors with stem cells signatures and correlate with clinical features in order to expand our comprehension of tumor biology. The identification of tumors with stem cell phenotype may improve the current tumor classification and in turn may allow better prediction of tumor behavior and ultimately may lead to preventive therapies for individuals at high risk of developing cancer. By integrating stem cell signatures and cancer, we expect our findings will enrich our understanding of tumor biology and open opportunities for improved therapeutic protocols. In addition, the resulting collaboration in this initiative have complementary expertise that will ensure a robust exchange of expertise and the accomplishment of this current proposal. (AU) | |
