The Role Of Adenovirus Serotype 5 E4 11k In The Relocalization Of The Cellular P Body Proteins, Kasey A. Karen, La`Quita Randolph, Kevin Neubrecht, Heather Vincent
The Role Of Adenovirus Serotype 5 E4 11k In The Relocalization Of The Cellular P Body Proteins, Kasey A. Karen, La`Quita Randolph, Kevin Neubrecht, Heather Vincent
Georgia Journal of Science
Human adenoviruses are a useful tool to understand basic cellular biology in addition to viral infections. Historically, cellular splicing was first discovered in adenovirus, but other cellular processes, such as double-strand break repair and aggresome formation, have been further elucidated through adenoviral infection. The adenovirus protein E4 11k has been shown to disrupt cytoplasmic processing bodies (p bodies), which are not well-understood but are involved in mRNA metabolism. Several p body proteins were found to be reorganized in the cytoplasm with adenovirus serotype 5 (Ad5) able to cause the colocalization of these p body proteins with aggresomes. The p body …
Integrated Regulation Of Class Ii Human Endogenous Retroviruses In A Breast Cancer Cell Line, Yingguang Liu, Tam D. Nguyen
Integrated Regulation Of Class Ii Human Endogenous Retroviruses In A Breast Cancer Cell Line, Yingguang Liu, Tam D. Nguyen
Proceedings of the International Conference on Creationism
Endogenous retroviruses (ERVs) are still regarded as foreign invaders by most biologists. Because of structural and positional homology of ERVs in human and ape genomes, they have been considered molecular evidences of common ancestry. Using a breast cancer cell line, we analyzed the regulatory features of a group of human endogenous retroviruses (HERV-K), and found that they contain multiple sequence motifs subjecting them to regulation by sex hormones, a stem cell-specific transcription factor (OCT4), and DNA methylation. Mutation of the OCT4 motif abrogates their response to sex hormones, while methylation of a progesterone-response element enhances receptor-binding. We also found that …
Effects Of Adenovirus Infection On The Localization Of Cellular Protein Pat1b, Emilee Friedman, Kasey A. Karen
Effects Of Adenovirus Infection On The Localization Of Cellular Protein Pat1b, Emilee Friedman, Kasey A. Karen
Georgia Journal of Science
Adenoviruses are a diverse family of nonenveloped, double-stranded DNA viruses with a variety of vertebrate hosts including humans. Over 50 serotypes of human adenovirus have been identified, and cause a number of illnesses, including conjunctivitis, gastroenteritis, and respiratory infections. The life cycle of adenovirus is divided into immediate early, early, and late phases, with immediate early proteins controlling transcription and the cell cycle, early proteins being largely regulatory, and late proteins being structural. Early proteins such as E4 11k have been demonstrated to relocalize key cellular proteins, including proteins found within mRNA processing bodies (p-bodies). It is hypothesized that E4 …
Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane
Chronic Inflammation As A Result Of Hepatitis C Virus Infection: A Review Of The Literature, Samantha L. Lane
DePaul Discoveries
Approximately 170 million people are infected with Hepatitis C virus (HCV) worldwide5,6. It is estimated that roughly 80% of those infected suffer from persistent infection with the virus; this persistence of infection is progressive, and over time can lead to fibrosis, cirrhosis, and hepatocellular carcinoma7. Chronic inflammation and apoptotic deregulation are both hallmarks of chronic HCV infection, and many molecular pathways are initiated in both the innate and adaptive immune responses during infection with this viral pathogen. The aim of this review was to survey some of the major molecular mechanisms responsible for the induction of …
Combating Bioterrorism: Purification And Structural Analysis Of The E3 Proteins Of The Venezuelan Equine Encephalitis Virus And The Chikungunya Virus, Tyshia Gwin
The Journal of Purdue Undergraduate Research
Outbreaks of the Venezuelan Equine Encephalitis Virus (VEEV) and the Chikungunya Virus (CHIKV) continue to emerge in Central and South America, Africa, and Asia, but there are currently no vaccines or anti-virals for these viruses. Given their ease of transmission, debilitating symptoms, and genetic alterability, VEEV and CHIKV have great potential for development into biological weapons. Therefore, there is an urgent need to determine possible methods of treatment or prevention. One possibility of prevention lies in determining the structure and biological function of the E3 protein that plays a key role in the infectivity of the viruses. In this research, …
