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 …

The role of steroid hormones is critical in cellular function. Previous studies have found a positive correlation between the endogenous estrogen 17β-estradiol and cellular protection. Conversely, exogenous conjugated equine estrogens provide less protective mechanisms than endogenous hormones, and little is known about the role of estrogens in cellular protection during a stress response. In the present study, we compare the effects of short-term estrogen pretreatments (alone and in combination) on cell viability when cells with glial cell morphology are exposed to either epinephrine or cortisol. Results showed that 1 µM 17β-estradiol resulted in decreased cell viability following the epinephrine treatment; …

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 …
