A data mining framework for genomics biomarker and signature identification

点击翻译按钮获取中文摘要

Biomarkers are indicators used to objectively measure and evaluate normal biological processes, pathogenic processes or pharmacological responses to therapeutic interventions. In medical practice, biomarkers facilitate diagnosis and prognosis of disease, as well as monitoring clinical response to therapy. In environmental studies, biomarkers can be used to assess the health states of animals and plants, with respect to, for instance, the amounts of toxic materials they are exposed. Advancements in the fields of genomics and proteomics have revolutionized novel biomarker discovery with new tools for high throughput strategies. In this proposal, we present a comprehensive framework for using large amounts of genomics and proteomics data for identifying biomarkers and signatures. The proposal has three key focuses: (A) data cleansing and pre-processing; (B) biomarker and signature identification; and (C) validation with real data sets.
