CAS Key Laboratory of Genome Sciences & Information
After the institute actively participated in the International Human Genome Project (HGP), the institute also led the Chinese Super-hybrid Rice Genome Project. Approved by CAS, the institute founded the CAS Key Laboratory of Genome Sciences and Information on November 2006 under the background of propulsion stage of CAS Knowledge Innovation Project propulsion and rapid development of genome science and bioinformatics. During the past several years, the laboratory has also made significant breakthroughs in the inheritance and reprogramming of epigenetic information in animals. In 2019, National Genomic Science Data Center of China was established.
2. Research direction
Based on the frontier fields of genomics and information technology, our library focuses on the national strategic demands of population health and biosecurity. We will develop new theories about genome structure, mutation, function and evolution, and we will also build new methods and technologies about the massive biological data acquisition, integration and mining. We aim to enhance the cross-fertilization of genomics and other disciplines and to promote integration and forward-looking research by data-driven genomic problem. Our major goal is to address key life sciences and technology issues such as public safety, biosecurity and data security. The research direction: (1) New mechanisms and theories in function genomics, (2) New technologies and methods for genomics, (3) Integration and mining of big data.

4. Annual research progress
We constructed an experimental framework to observe re-establishment of long-range chromatin interactions on nascent chromatin, and established an analysis pipeline to view interactions involving more than two regulatory elements. In addition, we utilized zebrafish to investigate DNA methylation reprogramming during juvenile germ cell development and adult female-to-male sex transition.
We revealed that primordial germ cells (PGCs) undergo significant DNA methylation reprogramming during germline development and Tet3 is involved in the process. Notably, we find that inhibiting DNMTs activity can prevent the female-to-male sex transition. Therefore, DNA methylation plays important roles in zebrafish germline development and sexual plasticity.
We proposed quasi-paired cohort strategy reveals the impaired detoxifying function of microbes in the gut of autistic children. (Science Advances, 2020).
Based on peripheral blood expression spectrum and machine learning framework, we established a detection model that can be applied to the detection of chronic and complex diseases including cardiovascular diseases, tumors and metabolic diseases. This model could eliminate batch effect, platform difference and ethnic difference. This method would improve the sensitivity of non-invasive screening and has been patented (Brief Bioinform, 2020).
We first reported a ST1265/K1 carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-HvKP) and revealed that the CR-HvKP evolved from HvKP through acquiring an antimicrobial-resistance plasmid (J Glob Antimicrob Resist, 2020).
The novel DNA storage technology developed by our group can reduce the cost and significantly improved the accuracy. We have applied for the patent (202010688281.X).
We present the dynamics of chromatin reprogramming during IVF, PA and AG embryogenesis. And we observed unsynchronized establishment of chromatin architecture between the uniparental embryos and IVF. (Genome Biology, 2020).
We developed a new trans-splicing detection tool (TSD), and revealed spatial clustering feature of trans-splicing (Science China -Life Sciences, 2020).
In 2020, the National Genomics Data Center developed 8 new databases (2019nCoVR, Aging Atlas, BrainBase, CGIR, GTDB, LncExpDB, scMethBank and TransCirc), and updated a series of resources, involving multiple biological contexts such as disease, aging, regulation and biodiversity (Nucleic Acids Res, 2021).
