Department of Biochemistry: Faculty Publications

Advances in quantitative biology data collection and analysis across scales (molecular, cellular, organismal, and ecological) have transformed how we understand, categorize, and predict complex biological systems. This surge of quantitative data creates an opportunity to apply, develop, and evaluate mathematical models of biological systems and explore novel methods of analysis. Simultaneously, thanks to increased computational power, mathematicians, engineers, and physical scientists have developed sophisticated models of biological systems at different scales. Novel modeling schemes can offer deeper understanding of principles in biology, but there is still a disconnect between modeling and experimental biology that limits our ability to fully realize …

Standardizing Resident Education On Gi Service, Jennifer Halma, Kenneth Schmidt

Posters

Introduction: The pediatric residency curriculum at Children’s Mercy Hospital is standardized to offer each trainee the same rotational experience. As a result, each resident spends one month on the inpatient gastroenterology (GI) service during training. This invites variability in the quantity and quality of GI education that residents receive. Therefore, there is a need to design a standard curriculum to provide comprehensive GI education. The aim of this project is to standardize resident education by identifying most requested topics and providing didactic education to increase resident general GI knowledge. Methods: Each month, residents were provided with a survey to assess …

Effects Of A N2-Fixing Biofertilizer On The Rhizosphere Microbiome And The Influence Of Biochar On Soil Fertility And Microbial Communities, Sarbjeet Niraula Dec 2021

Effects Of A N2-Fixing Biofertilizer On The Rhizosphere Microbiome And The Influence Of Biochar On Soil Fertility And Microbial Communities, Sarbjeet Niraula

Biology Dissertations - Archive

The rhizosphere microbiota and endosymbionts are the major contributors to biogeochemical cycling and significantly impact the associated host plant. Their association with plant roots is inevitable for plant health and development. The application of bio inoculants that promote plant growth and productivity is a promising alternative to chemical fertilizers in agricultural fields because of their nutrient solubilization activity, and are considered environmentally safe. However, their impact on the soil microbiome has been least studied. The use of bio-inoculants may have favorable or unfavorable impacts on the native microbial community in the rhizosphere. Therefore, we attempt to evaluate the effects of …

Of Single Nucleotides And Single Cells: Charting The Genotype-Phenotype Map At High Resolution Using Drosophila Melanogaster, Sneha Shreekant Mokashi Dec 2021

Of Single Nucleotides And Single Cells: Charting The Genotype-Phenotype Map At High Resolution Using Drosophila Melanogaster, Sneha Shreekant Mokashi

All Dissertations

Understanding the mechanisms by which genetic variation brings about phenotypic variation is essential for understanding variation in complex traits. Drosophila melanogaster is a powerful model organism for such studies. Flies are easy to raise in the laboratory under controlled genetic and environmental conditions and many genetic tools are widely available. To chart the genotype-phenotype map, we need to study how individual genetic variants contribute to phenotypic variation, as well as how environmental perturbations influence gene expression.

Regarding the former, I generated single nucleotide substitutions in Obp56h in a common genetic background. Obp56h, a member of the Odorant binding protein …

Humboldt Journal of Social Relations

Deaths from unintentional injuries are the seventh leading cause of death among older adults and falls account for the largest percentage of these deaths, with individuals aged ≥85 particularly vulnerable. Physical activity can reduce frailty and prevent falls; however, many elders are not physically active and women, ethnic minorities, and those with low education levels are the least active. Moreover, experiences of racial discrimination can lead to increased stress and unhealthy adaptive behaviors, and the cumulative effects of age and race related stressors have been shown to negatively impact the physical and mental health of elderly African Americans. Thus, participation …

Zinc is an essential cofactor for bacterial metabolism, and many Enterobacteriaceae express the zinc transporters ZnuABC and ZupT to acquire this metal in the host. However, the probiotic bacterium Escherichia coli Nissle 1917 (or “Nissle”) exhibits appreciable growth in zinc-limited media even when these transporters are deleted. Here, we show that Nissle utilizes the siderophore yersiniabactin as a zincophore, enabling Nissle to grow in zinc-limited media, to tolerate calprotectin-mediated zinc sequestration, and to thrive in the inflamed gut. We also show that yersiniabactin’s affinity for iron or zinc changes in a pH-dependent manner, with increased relative zinc binding as the …

Obesity is primarily a consequence of consuming calories beyond energetic requirements, but underpinning drivers have not been fully defined. 5-Hydroxytryptamine (5-HT) neurons in the dorsal Raphe nucleus (5-HTDRN) regulate different types of feeding behavior, such as eating to cope with hunger or for pleasure. Here, we observed that activation of 5-HTDRN to hypothalamic arcuate nucleus (5-HTDRN → ARH) projections inhibits food intake driven by hunger via actions at ARH 5-HT2C and 5-HT1B receptors, whereas activation of 5-HTDRN to ventral tegmental area (5-HTDRN → VTA) projections inhibits non-hunger-driven feeding via actions at 5-HT2C receptors. Further, hunger-driven feeding gradually activates ARH-projecting 5-HTDRN …

Despite good adherence to supervised endurance exercise training (EET), some individuals experience no or little improvement in peripheral insulin sensitivity. The genetic and molecular mechanisms underlying this phenomenon are currently not understood. By investigating genome-wide variants associated with baseline and exercise-induced changes (∆) in insulin sensitivity index (Si) in healthy volunteers, we have identified novel candidate genes whose mouse knockouts phenotypes were consistent with a causative effect on Si. An integrative analysis of functional genomic and transcriptomic profiles suggests genetic variants have an aggregate effect on baseline Si and ∆Si, focused around cholinergic signalling, including downstream calcium and chemokine signalling. …


A Solution To The Hard Problem Of Soft Law, Keagan Potts Dec 2021

A Solution To The Hard Problem Of Soft Law, Keagan Potts

Michigan Journal of Environmental & Administrative Law

Administrative Agencies often rely on guidance documents to carry out their statutory mandate. Over the past few decades, the Food and Drug Administration (FDA) has been criticized for using soft law guidance documents to exercise powers beyond those authorized by Congress. Since attacks on the use of guidance documents persist and agencies need soft law to respond quickly and flexibly to rapid technological growth, it is essential to develop a solution that preserves this crucial regulatory mechanism and prevents its abuse. The most likely alternative to soft law guidance is formal regulation, which must be developed through the notice-and-comment process. …

Division of Basic Science Faculty Publications

Due to its pivotal role in autonomic networks, the vagus attracts continuous interest from both basic scientists and clinicians. In particular, recent advances in vagus nerve stimulation strategies and their application to pathological conditions beyond epilepsy provide a good opportunity to recall basic features of vagal peripheral and central anatomy. In addition to the “classical” vagal brainstem nuclei, i.e., dorsal motor nucleus, nucleus ambiguus and nucleus tractus solitarii, the spinal trigeminal and paratrigeminal nuclei come into play as targets of vagal afferents. On the other hand, the nucleus of the solitary tract receives and integrates not only visceral but also …

Contrasting to the established role of the hypothalamic agouti-related protein (AgRP) neurons in feeding regulation, the neural circuit and signaling mechanisms by which they control energy expenditure remains unclear. Here, we report that energy expenditure is regulated by a subgroup of AgRP neurons that send non-collateral projections to neurons within the dorsal lateral part of dorsal raphe nucleus (dlDRN) expressing the melanocortin 4 receptor (MC4R), which in turn innervate nearby serotonergic (5-HT) neurons. Genetic manipulations reveal a bi-directional control of energy expenditure by this circuit without affecting food intake. Fiber photometry and electrophysiological results indicate that the thermo-sensing MC4RdlDRN neurons …

Objective: Obesity and upper-body fat elevates cardiometabolic risk. However, mechanisms predisposing to upper-body fat accumulation are not completely understood. In males, low testosterone (T) frequently associates with obesity, and estrogen deficiency may contribute to upper-body adiposity. This study examines the effects of overfeeding-induced weight gain on changes in gonadal hormones in healthy males and its association with regional fat depots. Methods: Twenty-five males (age: 29.7 ± 6.9 years; BMI: 24.7 ± 3.1 kg/m2) were overfed for 8 weeks to gain approximately 5% body weight. Changes in total and regional fat depots were assessed using dual-energy x-ray absorptiometry and abdominal computed …

The initial sensing of dietary methionine restriction (MR) occurs in the liver where it activates an integrated stress response (ISR) that quickly reduces methionine utilization. The ISR program is regulated in part by ATF4, but ATF4’s prototypical upstream regulator, eIF2α, is not acutely activated by MR. Bioinformatic analysis of RNAseq and metabolomics data from liver samples harvested 3 h and 6 h after initiating MR shows that general translation is inhibited at the level of ternary complex formation by an acute 50% reduction of hepatic methionine that limits formation of initiator methionine tRNA. The resulting ISR is induced by selective …


Nt-Pgc-1Α Deficiency Attenuates High-Fat Diet-Induced Obesity By Modulating Food Intake, Fecal Fat Excretion And Intestinal Fat Absorption, Jihyun Kim, Jiyoung Moon, Chul Hong Park, Jisu Lee, Helia Cheng, Z. Elizabeth Floyd, Ji Suk Chang Dec 2021

Nt-Pgc-1Α Deficiency Attenuates High-Fat Diet-Induced Obesity By Modulating Food Intake, Fecal Fat Excretion And Intestinal Fat Absorption, Jihyun Kim, Jiyoung Moon, Chul Hong Park, Jisu Lee, Helia Cheng, Z. Elizabeth Floyd, Ji Suk Chang

Division of Basic Science Faculty Publications

Transcriptional coactivator PGC-1α and its splice variant NT-PGC-1α regulate metabolic adaptation by modulating many gene programs. Selective ablation of PGC-1α attenuates diet-induced obesity through enhancing fatty acid oxidation and thermogenesis by upregulation of NT-PGC-1α in brown adipose tissue (BAT). Recently, we have shown that selective ablation of NT-PGC-1α reduces fatty acid oxidation in BAT. Thus, the objective of this study was to test our hypothesis that NT-PGC-1α−/− mice would be more prone to diet-induced obesity. Male and female NT-PGC-1α+/+ (WT) and NT-PGC-1α−/− mice were fed a regular chow or 60% high-fat (HF) diet for 16 weeks. Contrary to our expectations, …
