He has made substantial contributions to (1) characterization, modeling, and prediction of cancer evolution from genomics (Nat Genet 2016; Nat Genet 2017; Nat Commun 2021); (2) discovery, elucidation, and clinical application of MGMT fusion (Nat Genet 2016; Nat Commun 2020) and METex14 in adult gliomas (Nat Genet 2018; Cell 2018); (3) discovery of MAP3K3-I441M in CCM (AJHG 2021) and elucidation of EndMT in bAVM (Circ Res 2021); (4) reconstruction of RNA Exosome-regulated non-coding transcriptomes (Nature 2014; Cell 2015). He won the Excellent Young Scientist Award of NSFC (2019), the School of Engineering Young Investigator Research Award (2019), the School of Science Research Award (2021), and the Zhong Nanshan Youth Science and Technology Innovation Award (2021).


 


Research Question


 


Recent advances in next-generation sequencing are revolutionizing numerous areas in life science and medicine. Prof. Wang's research is focused on discovering and elucidating functional genomic alterations in complex human diseases, such as intracranial cancers and vascular malformations, by developing and/or applying computational methods based on multi-omics integration, statistics, and machine learning, aiming to bridge the gaps among data, bench, and bedside. More specifically, Prof. Wang's team has been mainly working on the following two scientific questions.


 


Question 1: How does clonal evolution drive cancer progression that leads to malignant transformation and therapeutic resistance?


 


Clonal evolution of cancer is a major challenge leading to treatment failure, but the molecular mechanisms of how cancer cells evolve and gain the capability of surviving intensive chemo- and/or radio- therapies remain elusive. Therefore, it is critically important to characterize the spatial and temporal dynamics of cancer cells and thereby mathematically modelling this process via big data integration. We have been working on diffuse gliomas, the most common and aggressive forms of primary tumors in adult brain whose treatment outcome is still very poor. Current therapies inevitably lead to tumor recurrence and the recurrent gliomas commonly become treatment resistance and incurable. Analyzing longitudinal and single-cell multi-omics data on this disease, our team aims to address the following questions: a) why cancer cells always display complex patterns of intratumoral heterogeneity; b) what is the temporal order of multiple somatic mutations detected in various cancer clones; c) how to predict the evolutionary path and clinical response of cancer cells under a certain therapy based on the sign seen earlier; and d) what are the key factors in tumor and its microenvironment that shape cancer evolution and determine cancer cell response under clinical intervention. In the process of addressing these questions, we will be able to unravel the mysteries of cancer evolution and it might provide a theoretical foundation for designing new means of treatment or diagnostics for better precision cancer medicine via targeting cancer dynamics.


 


Question 2: What is the role of genetic interaction between germline variants and somatic mutations in initializing and regulating the development of cancer and other genetic disorders?


 


Somatic genomic and epigenomic mutations are regarded as the direct drivers of cancer initialization and evolution, whereas de novo and inherited germline alterations could predispose the cancer risk and regulate population-specific disease incidence and treatment response. However, the underlying genetic interactions between germline variants and somatic mutations remain unclear, and the biological and medical implications of these interactions have not been extensively explored. New technologies of genomic sequencing allow low-cost profiling of somatic and germline mutations in not only case-unaffected-parental trios but also disease lesions at a high resolution, providing a unique opportunity to systematically investigate disease-relevant genomes by uncovering the joint contribution of the germline variants and somatic mutations in the process of disease development. Understanding whether and how the germline risk alleles interact with somatic mutations in terms of pathway activation and/or cellular interaction will help us to better understand disease etiology for the purpose of developing novel methods for genome-guided disease risk evaluation and personalized clinical intervention.
