Abstract:Recent genomic studies suggest that potential novel long noncoding RNAs (lncRNAs) are specifically expressed and far outnumber annotated ncRNA sequences. To identify and characterize novel lncRNAs in sequencing data from new samples, we have developed a bioinformatics software package (http://software.ncrnalab.org) that includes 3 modules: RNAfinder, RNAstructurome and RNAtarget. We have applied them to many biological (i.e., plant) and medical (i.e., cancer) applications. For instance, based on RNAfinder, we have identified ~8K novel lncRNAs in HCC (liver cancer) samples. Many of them were further validated as metastasis associated lncRNA biomarkers.

Currently, the main research focus of our lab is to identify and study novel extra-cellular RNA (exRNA) biomarkers in bio-fluids associated with tumorigenesis and cancer development, using machine learning (AI) approaches and high-throughput sequencing technologies. By analyzing dynamic expression and variants, we hope to find novel exRNA species related to tumorigenesis and/or cancer progression from cell-free plasma/serum, micro-vesicles, exosomes, and RNPs. The identified exRNA biomarkers are applied to the most lethal cancer in China. Finally, we will deliver an accurate, reproducible and robust method for cancer early diagnosis and/or prognosis.
