About this Research Topic
Next-Generation Sequencing (NGS) technology has been successfully applied in disease diagnostics, oncological immunotherapy, and drug repurposing, especially for precision medicine where optimized medication is tailored to individual patients. Recently, the development of single cell techniques makes it possible to examine gene expression and mutation at individual cell resolution, which provides an unprecedented opportunity to study cell development and differentiation, and reveal cell-to-cell heterogeneity during disease development, treatment and drug response for individual patients. With the exponential increase of single cell sequencing data, it is critical to develop appropriate bioinformatics and machine learning tools to mine the rules behind them. However, due to the technical barriers in single cell sequencing and the noisy nature of raw sequencing data, this task is challenging especially in the context of disease diagnosis and drug development.
To promote the translation and efficient usage of single cell sequencing data to precision medicine, it is necessary to develop new analysis tools for analyzing and integrating multi-level single cell data including DNA, RNA, protein and so on, comparing existing methods and results derived from different studies, and enhancing disease diagnostics and drug development. For example, the quality control, normalization, differential gene calling and clustering methods are quite different between single cell sequencing and traditional bulk cell sequencing. Thus, it is critical to develop a best practice specifically for dealing with single cell sequencing data. For disease treatment, it is also important to identify disease driver genes common to all cell types as well as those specific to a particular cell type or subgroup as revealed by single cell techniques, based on existing or novel network and machine learning-based methods. Finally, more translational work should be done to bridge the bioinformatics analyses and clinical applications for single cell researchers.
