The main purpose of pharmaceutical production is to produce safe effective medicine for patient use. In an effort to ensure patient safety constant surveillance for viruses takes place. The detection of a viral nucleic acid in a pharmaceutical production setting results in investigations to assess its infectious potential. This is an intensive, expensive process that entails many tests such as the observation of hemadsorption, cytopathic effects (CPE), and more. These tests are typically specific and only capture certain viruses, as factors like CPE can only be observed in some viral species. A new investigational method that is effective on all …

Flaviviruses include several emerging and re-emerging arboviruses that cause millions of infections each year. Although relatively well-studied, much remains unknown regarding the mechanisms and means by which these viruses adapt to different hosts and rapidly alternate between hosts. Different aspects of flaviviral biology impact host switching, viral fitness, and the generation of viral diversity during genome replication by the NS3 and NS5 proteins. Together these factors may impact host plasticity.

Ribosomes have been traditionally viewed as invariable machinery, but in recent years more and more evidence for their heterogeneity has emerged. Core ribosomal proteins, ribosomal-associated proteins, and post-translational modifications all contribute to the variations found within these crucial subcellular components.In our research, we focused on lysine acetylation – a post translational modification found on many ribosomal proteins. We used a chemical inhibitor of acetyltransferases KAT 3A and KAT 3B to observe the effect that inhibiting acetylation may have in the context of translation. By using poliovirus to shut off conventional cellular translation, we were able to look at a narrow …

In 1969, the enrichment of mobile element repeat sequences led Britton and Davidson to propose the hypothesis that gene expression in higher eukaryotes is regulated through the exaptation of mobile elements. In this work, I have explored the hypothesis that mobile elements can also be harnessed by the host to regulate asymmetric cell division, thereby determining cell fate. Retrotransposons are ubiquitous eukaryotic mobile elements that transpose through an RNA intermediate. They are often active in cell types that divide asymmetrically to yield daughter cells with different fates, such as embryonic stem cells, germline stem cells, neuronal stem cells and the …
Regulation Of Gene Expression Through Ribosome-Associated Proteins, Clare Margaret Miller
Regulation Of Gene Expression Through Ribosome-Associated Proteins, Clare Margaret Miller

Translation is a crucial mechanism for generating proteins to carry out cellular processes and for ensuring proper cell functions. Ribosomes are at the center of translation and are complex pieces of machinery. They consist of at least 80 core eukaryotic ribosomal proteins, which are conserved from prokaryotes, and four ribosomal RNAs (rRNAs): 18S, 28S, 5,8A 5S. In addition, numerous translation factors aid the ribosome in protein production. While ribosomes are typically described by these core features, they are known to exist in a heterogenous pool with variations in protein composition, modifications of rRNA, and an assortment of non-ribosomal proteins that …

Human immunodeficiency virus type 1 (HIV-1) is a retrovirus belonging to the lentivirus genus of the orthoretrovirinae family. HIV-1 is widely known for causing acquired immunodeficiency syndrome (AIDS) in humans and being responsible for 1.8 million deaths due to AIDS associated illnesses in 201016.
