Evolutionary relationshipsThe goal of our studies is to comprehensively probe transcriptome complexity across species (especially for human vs. other non-human primates). It has been recognized that several post-transcriptional events such as alternative splicing (including cis- and trans-splicing) and RNA editing can generate many different transcript isoforms from the same genes, increasing the complexity of transcriptome/proteome. Despite the small genetic differences, human and other primates exhibit fairly different phenotypes. Some diseases attracting attention extensively such as Alzheimer's and Parkinson's disease, autism spectrum disorders, hepatitis B/C, AIDS, and cancers either are specific to human or have different symptoms/severity in non-human primates. Therefore, comparative genomics/transcriptomics analyses between human and non-human primates may not only increase our understanding of human (or primate) evolution but also radiate some light on the molecular mechanisms underlying such differences between primates in disease susceptibility. Recently, the next-generation sequencing technologies have been demonstrated to have the tremendous power of both profiling coverage and quantitative accuracy in genomics and transcriptomics studies. Based on such technologies, we analyze transcriptome variations (diversity/divergence) at both the DNA and RNA levels and try to shed light on decryption of different “RNA codes” in primates. Our research directions include:

  • identification of gene structures and post-transcriptionally co-linear/non-co-linear events (including trans-spiced and circular RNAs);
  • functional and evolutionary analysis of post-transcriptional events;
  • investigation of dynamic transcriptomes during neural differentiation of human/non-human primate embryonic stem cells;
  • identification and analysis of genetic variations between human and non-human primates;
  • analysis of impacts of varied biological factors on evolutionary rates; and
  • annotation of crop genomes.
