Brief Introduction of Prof WANG

Research interests: The rapid progress of genome science in recent years has made revolutionary impact on biology and medicine. Analyzing life process at the genome level provides systems information to understand the biological basis of physiology and diseases. I have worked on multiple genomics topics as exemplified by the followings:

Transcriptome studies: Gene expression reflects biological activities of the genome under physiological and pathological conditions. We studied transcriptome in the areas of annotating the transcribed regions in the genomes of human, Drosophila and rice, normal gene expression in early hematopoiesis including stem/progenitor cells, pre-B cells, pre-T cells, myeloid progenitors, NK progenitors, erythroid progenitors, abnormal gene expression in myeloid cells in acute myeloid leukemia, and fusion genes in normal-karyotype acute myeloid leukemia. We are performing genome-scale promoter mapping analysis to identify the altered gene expression regulation in multiple diseases.

Genomic study of familial breast cancer: Breast cancer is a leading cancer in women worldwide. Approximately 10% of breast cancers are clustered in family setting with multiple members affected (familial breast cancer), caused by the genetic predispositions inherited in the disease family. This is best demonstrated by the BRCA1 germline mutations (BRCA1+) in disease families that a woman who inherits a pathogenic BRCA1 pathogenic mutation has 70-80% chance of developing breast cancer by the age of 70. However, genetic predispositions have been identified in about 40% of the disease families. Since joining UNMC, my laboratory has been studying familial breast cancer, aiming to better understand genetic basis of the disease, and to provide new genetic markers for early prevention, diagnosis and personalized treatment of the disease. We are using next generation sequencing-based approaches to study the nature of genome instability in BRCA1+ families, and unknown genetic predisposition in the disease families without known predisposition (BRCAx). We are persuading the study through campus-wide, national-wide, and international-wide collaborations.

Prof WANG’s study has been supported by grants from the National Human Genome Research Institute and National Cancer Institute of National Institute of Health, the Department of Defense, and multiple foundations.
