Investigating The Escape Mechanism Of Sre Bearing Mrna Transcripts During Viral Host Shutoff, Daniel Macveigh-Fierro

During viral infection, the virus and host clash for control over gene expression in an evolutionarily arms race that has raged for thousands of years. During lytic replication, Kaposi’s sarcoma associated herpesvirus (KSHV) triggers a massive RNA decay event known as host shut off. This causes over 70% of all RNA to be degraded suppressing the host antiviral response while freeing resources for viral replication. Our lab focuses on a subset of transcripts that escape from this viral degradation event using a cis acting 3’ UTR element known as a “SOX resistant element” or SRE. Although we have identified a …

Detection And Control Of Environmentally Transmissible Viruses, Anand R. Soorneedi
Doctoral Dissertations
Viruses, owing to their ubiquitous nature and ability to infect almost every other species, have long been a subject of interest for scientists. Some of the virus species can be very deadly to humans and animals alike and can impose a huge economic and health burden across the world. The recent CoVID-19 pandemic underscores the importance of timely detection for developing effective intervention strategies. Unfortunately, some of the virus species that cause significant health and economic impacts do not have robust and reliable detection methods due to several reasons. In some cases, despite having gold standard methods for detection of …

During viral infection, virus and host clash for control of the cell in a conflict that ultimately drives the evolution of both sides and has lasting consequences in the form of pathogenesis. At the heart of this struggle is a contest for control of cellular gene expression, a struggle epitomized by an evolutionary tug-of-war for supremacy over RNA fate. During lytic replication, Kaposi’s sarcoma-associated herpesvirus (KSHV) triggers a massive RNA decay event known as viral “Host Shutoff” which decimates greater than 70% of the host transcriptome, simultaneously suppressing the cellular anti-viral response and freeing host resources for viral replication. However, …

The divergence of the two superfamilies belonging to the Infraorder Catarrhini –Cercopithecoidea (Old World monkeys) and Hominoidea (apes, including humans) – is generally assumed to have occurred during the Oligocene, between 38 and 20 million years ago. Genetic studies indicate that this time period was one of active genetic evolution under strong purifying selection for catarrhine primates. This includes selective pressures on the glycoprotein galactosyltransferase 1 (GGTA1) gene and subsequent inactivation “clocked” at approximately 28 ma, possibly prior to the Cercopithecoidea/Hominoidea split. The GGTA1 gene codes for an a1,3 galactosyltransferase (GT) enzyme that synthesizes a terminal disaccharide, …
