Area of Interest
Approximately 1/4 of all human cancers are of viral origin or require viral infection as an essential cofactor. The main goal of our research is to understand cancers that are caused by Kaposi sarcoma-associated herpesvirus (KSHV). In the U.S., KS is seen in the context of HIV or transplant patients. In Sub-Saharan Africa, KS is the most common cancer in males and is also seen in children.
(1) We have developed transgenic mice expressing the viral proteins and micro RNAs. These provide an animal model for understanding KS biology and drug testing.
(2) Exosomes are a new and exciting area of research in the lab. Exosomes are on 50-120 nm particles, which like viruses, carry proteins and miRNAs to neighboring cells and are intricately linked to viral pathogenesis.
(3) We established the UNC Vironomics core to apply cutting-edge genomic technologies, such as next-generation sequencing, to viral genomes, viral and human gene expression, and BCR/TCR sequencing. This includes single-cell measurements and utilizes samples from clinical trials in the U.S., South Africa, and Malawi.
The UNC Vironomics core operates several NGS instruments, such as the PacBio Sequel II, Ion Torrent Genexus, and BD Rhapsody.
