The contribution of two phosphorylated surface modifications on the pathogenesis of Campylobacter upsaliensis
DownloadFall 2012
Campylobacter upsaliensis is a human pathogen most commonly associated with self-limiting gastroenteritis. Despite extensive epidemiological data indicating C. upsaliensis as an emerging pathogen, few studies have examined possible mechanisms of its virulence. The surface of C. upsaliensis is...

The Cpx and Rcs responses signal envelope stress through independent mechanisms but are coordinated through the RprA sRNA in the cytoplasm
DownloadFall 2018
Bacteria have several mechanisms which play a major role in adaptation to environmental stresses. One method involves the use of signal sensing pathways that activate transcription of specific genes encoding proteins to alleviate bacterial stress. Upon sensing an inducing cue, an inner...

The fitness and survival of bacteria depends on their ability to adapt and survive in different ecological niches during its life cycle. Bacteria must therefore be able to sense the different changes in the environment during the transition between different ecological niches to enhance survival....

The Cpx envelope stress response of Escherichia coli regulates and is regulated by the small RNA RprA
DownloadFall 2015
When bacteria sense changes in their environment, they adapt by altering the expression of their genes in such a way that accommodates the change. To do this, bacterial cells can modulate the activity of their genes at either the level of transcription, or at the post-transcriptional level....

Bacteria need to adapt to the ever-changing conditions in the environment and Escherichia coli employs the Cpx two-component system to protect the envelope, which consists of the inner membrane, periplasm, peptidoglycan, and outer membrane. Cpx is known to sense and respond to protein misfolding...

The Cpx stress response regulates turnover of respiratory chain proteins at the inner membrane of Escherichia coli
DownloadSpring 2022
The cell envelope of Gram-negative bacteria is a unique multilayered structure that protects them from the constantly changing and often times inhospitable environments, and significantly contributes to their virulence. Having a complex structure, it requires an extensive regulatory network to...

The development and biomechanics of theropod teeth and comparisons with other reptiles: a functional analysis
DownloadSpring 2012
Teeth are important for taxonomic studies. They are often the only remains found of certain vertebrates in the fossil record. This is because they are more resistant to weathering than most bones, they are small, and they are generally abundant. Most reptiles have homodont dentition, and the...

Hagfish are considered the oldest living representatives of the vertebrates and as such are of interest for studies in evolutionary biology. Moreover, hagfish occupy a unique trophic niche wherein they are active predators and benthic scavengers of a wide range of invertebrate and vertebrate...
