Considering Microbial Pesticides As A Disease Mitigation Strategy For The Amphibian Fungal Disease, Chytridiomycosis, Denita Mychele Weeks Jan 2018

Considering Microbial Pesticides As A Disease Mitigation Strategy For The Amphibian Fungal Disease, Chytridiomycosis, Denita Mychele Weeks

Electronic Theses and Dissertations Archive

Chytridiomycosis is an infectious amphibian disease caused by the pathogenic fungus Batrachochytrium dendrobatidis (Bd). Bd attaches to keratin on the epidermis of amphibians, invades skin cells, and may lead to pathogenesis in susceptible individuals. However, susceptibility varies within and among species. While this is due to many factors, the skin microbial community is a significant contributor to disease resistance. Amphibians form symbiotic relationships with environmental microbes on the skin surface, some of which produce antifungal agents that inhibit Bd. Interestingly, many agricultural biopesticides utilize the common soil-dwelling bacteria, Bacillus thuringiensis. Through agricultural use, these bacteria likely increase in environmental abundance …

Map3k4 Controls The Chromatin Modifier Hdac6 During Trophoblast Stem Cell Epithelial To Mesenchymal Transition, Robert Jackson Mobley Jan 2018

Map3k4 Controls The Chromatin Modifier Hdac6 During Trophoblast Stem Cell Epithelial To Mesenchymal Transition, Robert Jackson Mobley

Electronic Theses and Dissertations Archive

The first epithelial to mesenchymal transition (EMT) occurs in trophoblast stem (TS) cells during implantation. Inactivation of the serine/threonine kinase MAP3K4 in TS cells (TSKI4 cells) induces an intermediate state of EMT, where cells retain stemness, lose epithelial markers, and gain mesenchymal characteristics. Investigation of relationships among MAP3K4 activity, stemness, and EMT in TS cells may reveal key regulators of EMT. Here, we show that MAP3K4 activity controls EMT through the ubiquitination and degradation of HDAC6. Loss of MAP3K4 activity in TSKI4 cells results in elevated HDAC6 expression and the deacetylation of cytoplasmic and nuclear targets. In the nucleus, HDAC6 …

Role Of Breastfeeding Duration, Maternal Smoking During Pregnancy, And Dna-Methylation For The Risk Of Eczema, Nandini Mukherjee

Electronic Theses and Dissertations Archive

Prior studies linking breastfeeding duration and maternal gestational smoking, respectively, to offspring eczema report contradictory findings. However, it is not known whether maternal gestational smoking and breastfeeding duration can jointly influence eczema and whether these exposures mediate their effect on eczema via DNA Methylation (DNA-M) of CpG (cytosine-phosphate-guanine) sites. With data from the Isle of Wight (IOW) birth cohort, UK, we first evaluated the combined effect of maternal gestational smoking and breastfeeding duration on eczema at ages 1-to-2 (n=980), 4 (n=902), 10 (n=966), and 18 years (n=929) using Generalized estimating equations (GEE).

Biochemical Characterisation Of The Oscillatory Function Of Clock, Nimish Kathale Jan 2018

Biochemical Characterisation Of The Oscillatory Function Of Clock, Nimish Kathale

Electronic Theses and Dissertations Archive

Circadian clocks are oscillator systems that drive rhythms in behavior and physiology in an organism to coordinate with the light-dark cycle. The molecular clock is made up of core clock genes acting in a transcriptional negative feedback loop. Transcriptional activators BMAL1 and CLOCK form a heterodimer which binds to cis E/E-box elements present in the promoter region of target genes including Per1,2,3 and Cry1,2. PER and CRY proteins then translocate to the nucleus to repress BMAL1/CLOCK-mediated transcription. This transcriptional negative feedback mechanism underlies circadian oscillations. BMAL1 and CLOCK are bHLH and PAS domain transcription factors and play a central role …

Multiple Stimuli Responsive Drug Delivery System Based On Magnetic Nanoparticle Embedded Chitosan Microbeads, Ankita Mohapatra

Electronic Theses and Dissertations Archive

Direct drug administration has several shortcomings such as low circulation concentration due to rapid flushing by the immune system, non-specificity to target tissue and inefficient delivery to avascular sites. A widely adopted solution to these limitations is to sterically shield the drug from a harsh in vivo environment by encapsulation in a biocompatible, bio-degradable substrate. These Drug Delivery System (DDS) can be localized at the site and release drug gradually until the drug reserve is exhausted. However, the efficiency of this DDS can be further enhanced by designing them to elute drug in response to an external stimulus. This enhancement …
