Shift In Conformational Equilibrium Underlies The Oscillatory Phosphoryl Transfer Reaction In The Circadian Clock, Pyonghwa Kim, Neha Thati, Shreya Peshori, Hye-In Jang, Yongick Kim
Shift In Conformational Equilibrium Underlies The Oscillatory Phosphoryl Transfer Reaction In The Circadian Clock, Pyonghwa Kim, Neha Thati, Shreya Peshori, Hye-In Jang, Yongick Kim
Chemistry Faculty Research
Oscillatory phosphorylation/dephosphorylation can be commonly found in a biological system as a means of signal transduction though its pivotal presence in the workings of circadian clocks has drawn significant interest: for example in a significant portion of the physiology of Synechococcus elongatus PCC 7942. The biological oscillatory reaction in the cyanobacterial circadian clock can be visualized through its reconstitution in a test tube by mixing three proteins—KaiA, KaiB and KaiC—with adenosine triphosphate and magnesium ions. Surprisingly, the oscillatory phosphorylation/dephosphorylation of the hexameric KaiC takes place spontaneously and almost indefinitely in a test tube as long as ATP is present. This …
Potential Counter Regulatory Effects Of A Gut Microbiota Metabolite In Alleviating Down-Regulation Krüppel-Like Factor 4 In Intestinal Inflammation, Ylva Forslund
Theses, Dissertations and Capstones
Inflammatory bowel disease (IBD) is a medical condition characterized by chronic inflammation of the intestinal epithelium. Krüppel-like factor 4 (KLF4), a zinc finger transcription factor, is vital for maintaining intestinal epithelial homeostasis. KLF4 promotes differentiation of goblet cells that generate the protective mucus layer. Reduced goblet cell number and defective mucus layer are associated with IBD. Shortchain fatty acids (SCFA) are known to play an important role in the maintenance of a strong and healthy intestinal epithelial layer and also in goblet cell differentiation. However, whether the positive effects of SCFAs on goblet cells are mediated, at least partly, via …
The Effects Of Endocrine Disrupting Chemicals On Plants, Christian Mathew Pridemore
The Effects Of Endocrine Disrupting Chemicals On Plants, Christian Mathew Pridemore
Theses, Dissertations and Capstones
Endocrine disrupting chemicals (EDCs) are a diverse group of chemicals which can have a detrimental effect on human health, affecting any physiological body system sensitive to hormonal changes. Human exposure to EDCs is inevitable due to their prevalence in modern living; EDCs are integral compounds found in everyday items with which humans interact and ingest. These, along with other indirect avenues leading to EDC exposure, pose a threat to both human health and to the health of wildlife and agricultural environments. Studies on the effects of EDCs on plants can be substantially informative and necessary for progress towards solving the …
