Latent virus life cycles are no exception to this definition, as viruses are still reliant on host machinery for continued proliferation and maintenance of viral genomes, even in the absence of lytic replication. In this thesis, I used essentiality screening to identify host factors on which Kaposi's Sarcoma Associated Herpesvirus (KSHV) relies for the proliferation and survival of latently infected cells. KSHV is the etiological agent of Kaposi's Sarcoma (KS), an endothelial cell-based tumor where more than 90% of the endothelial cells in the tumor are latently infected with KSHV. While traditional therapies for herpesviruses target lytic replication, the prevalence of latency in KS necessitates exploration of options for intervening in this stage of the viral life cycle. I performed CRISPR/Cas9 screening using lentiviral vec- tors encoding a library of single guide RNAs (sgRNAs) targeting every protein coding gene in the human genome. I compared mock infected and KSHV infected endothelial cells eight days post infection to identify genes essential to latent KSHV infection.

  • New CRISPR-Based Test for COVID-19 Uses a Smartphone Camera 5 December 2020
    New CRISPR-based test for COVID-19 uses a smartphone camera 5 December 2020 spread the virus. In a new study published in the scientific journal Cell, the team from Gladstone, UC Berkeley, and UCSF has outlined the technology for a CRISPR- based test for COVID-19 that uses a smartphone camera to provide accurate results in under 30 minutes. "It has been an urgent task for the scientific community to not only increase testing, but also to provide new testing options," says Melanie Ott, MD, Ph.D., director of the Gladstone Institute of Virology The new COVID-19 test uses CRISPR gene-editing and one of the leaders of the study. "The assay we technology and a smartphone to provide a positive or developed could provide rapid, low-cost testing to negative test result and measure viral load.
