Title Single-sample networks for deciphering individual features in disease
Abstract
Recently, extracting inherent biological system information (e.g., cellular networks) from genome-wide expression profiles for developing personalized diagnostic and therapeutic strategies has become increasingly important. However, accurately constructing single-sample networks (SINs) to capture individual characteristics and heterogeneity in disease remains challenging. Here, we present a sample-specific weighted correlation network (SWEET) method to model SINs by integrating the genome-wide sample-to-sample correlation (i.e., sample weights) with the differential network between perturbed and aggregate networks [1]. Integrating SWEET SINs with a network proximity measure facilitates characterizing individual features and therapy in diseases, such as identifying repurposable drugs and predicting drug sensitivity in specific cancer cell lines. Moreover, the SWEET method can not only effectively discriminate different cancer types (or cell line types) but also identify two potential subtypes of lung adenocarcinoma with distinguishing clinical features. In this talk, I will introduce currently used SIN inference methods and how these methods compensate for the current analysis of omics data and offer a view of biological network systems to enable the development of next-generation personalized medicine and clinical decision support systems.
