Jones, John Matthew
- Abstract/Description

Minichromosome maintenance complex 2-7 (MCM2-7) is a fundamental component of the replicative CMG helicase (CDC45-MCM-GINS) characteristic of active eukaryotic replication forks. MCM2-7 is composed of 6 subunits, some of which are capable of receiving Dbf4-Cdc7 kinase (DDK) phosphorylation. Specifically, one of the six MCM2-7 subunits, MCM2, is associated with CMG complex activation upon MCM2 phosphorylation from DDK.

MCM2-7 is composed of 6 subunits, some of which are capable of receiving Dbf4-Cdc7 kinase (DDK) phosphorylation. Specifically, one of the six MCM2-7 subunits, MCM2, is associated with CMG complex activation upon MCM2 phosphorylation from DDK. Dr. Daniel Kaplan of Florida State University has developed an MCM2 phosphomutant (MCM2 11e) shown to mimic DDK phosphorylated MCM2, and therefore MCM2 that is present in active CMG helicase complexes [19]. Recent research of MCM2 has suggested accessory activities of the MCM2 protein aside from participation in the MCM2-7 ring of the CMG helicase complex. One particular function is histone chaperoning of H3-H4 dimers, a characteristic shared by chromatin assembly factor 1 (CAF-1). CAF-1 is known to deposit H3-H4 dimers at the replication fork, providing enough suspicion to investigate MCM2-CAF-1 interactions. In this Honors Thesis, GST pull-down assays were conducted to test MCM2 wild type (wt) and 11e binding efficiencies for 2 of 3 CAF-1 subunits, RLF2 and CAC2. Results indicate significant MCM2 wt affinity for RLF2, affinity not reciprocated by MCM2 11e. However, neither MCM2 wt nor 11e exhibit binding efficiencies greater than solely GST tag controls do for CAC2. The preferential binding of MCM2 wt to RLF2 and the shared repulsion of CAC2 by MCM2 wt and 11e identify MCM2 binding specificity to CAF-1 subunits not previously identified.

This project discusses performance and gender issues in the social comedies of Oscar Wilde. Despite his strong identification as an aesthete, privileging art for its own sake separate from the natural realm, Wilde's social comedies deal with very real challenges of women during a transitional period in the history of European feminism, just before suffrage in England became an issue and the role of women began to shift to the public sphere.

Show moreThis project discusses performance and gender issues in the social comedies of Oscar Wilde. Despite his strong identification as an aesthete, privileging art for its own sake separate from the natural realm, Wilde's social comedies deal with very real challenges of women during a transitional period in the history of European feminism, just before suffrage in England became an issue and the role of women began to shift to the public sphere. Wilde's comedies often been analyzed solely on the basis of text, rather than as pieces of art meant to be both viewed and read. My argument is that a full understanding of Wilde's plays requires both textual and performative analyses, and that Wilde's female characters, rather than the oft-studied male figures, are the characters that best exemplify the necessity of this dualistic study. In addition to looking at Wilde through the lens of performance theorists such as Judith Butler and Eve Sedgwick, this project analyzes adaptations of The Importance of Being Earnest and Lady Windermere's Fan from the silent film era to the present.

The former argues that it is never morally right to believe or accept a proposition beyond its evidential support; the latter defends the moral permissibility of a specific class of beliefs, including religious faith-commitments. I present interpretations of both essays, critiques of some contemporary arguments they have inspired and my own account of how to morally evaluate forming belief and acting on propositions. My thesis is that we must take seriously the moral consequences of belief when evaluating and choosing between alternative belief-forming practices and deciding to accept and act upon a proposition.

An important factor that can influence an individual to accept training is motivation. One aspect of motivation is the Socio-emotional Selectivity Theory framework that Carstensen, Isaacowitz, and Charles (1999) proposed. It sees time as fundamental to motivation, suggesting that people with shorter time frames will seek emotional gratifications and those with longer frames will prefer information seeking gratification to further their careers. I tested predictions from this framework. Individuals with shorter time frames until retirement should be less willing to participate in job-related training than those with longer time frames. After running regressions using data from Workforce Ageing in the New Economy (WANE) data set and taking into account additional factors such as the correlation of age with time until retirement and excluding those with extreme amounts of training, there was little support for this assumption. However, there is a trend in the right direction. Further studies need to be done to investigate types of training given, reasons for retirement at chosen time, personality, within different industries and firm sizes.

Show moreThis paper is an analysis on the autonomy and depiction of women in the Later Middle Ages. It will cover a period of over a hundred years with specific attention paid to the literature in this time period, which will be further supported by secondary sources to resolve gaps of knowledge. This was also the period in which the Hundred Years War (1337-1453) was waged and from where the English and French case studies of this paper originate. This century is important for context in the Later Middle Ages as this was a point in history that had a number of key events such as the Black Death as well as being one of the best preserved in terms of sources available.What this paper uncovered was that while in the Later Middle Ages women from both upper and lower classes were able to a certain extent act as independent agents; this was not reflected in the contemporary literature until towards the end of this period. By the end of this period however there was an increasing number of women that were detailed and credited for their actions without being compared to their male relatives, as being described as virtuous (as opposed to evil) because of their feminine traits, and that more classes of women were being represented within the literature.

The role of 19th century Japanese women is often misinterpreted by the West. While the late Tokugawa period was certainly a patriarchy, women of the samurai class were commonly taught how to wield weapons and defend their homes. This is particularly evident in the Battle of Aizu Wakamatsu during the Boshin War where women were very active in the fighting.

Show moreThe role of 19th century Japanese women is often misinterpreted by the West. While the late Tokugawa period was certainly a patriarchy, women of the samurai class were commonly taught how to wield weapons and defend their homes. This is particularly evident in the Battle of Aizu Wakamatsu during the Boshin War where women were very active in the fighting. This study hopes to understand the culture around these women at the time of the battle, and also look at their place in contemporary popular culture. To investigate this, I have gathered and read secondary sources regarding women in Japan and their role among warriors. In addition, I traveled to Japan to find primary sources and to visit sites pertinent to my research, such as the Tsurugajo Castle in Aizu Wakamatsu. I have also begun reading the translation of the memoirs of one of the women who fought at Aizu, Yamamoto Yaeko. To learn of their portrayal in popular culture, I have read a manga and watched a Taiga Drama, both of which focus on telling the story of Yamamoto Yaeko. Thus far, my research demonstrates that it was fairly common for women of the samurai class to learn martial arts. However, it was less common that they would participate in actual battles and the women of Aizu and others like them appear to be the exception to the rule.

Show moreThis thesis analyzes applications of Writing Across the Curriculum (WAC) and Writing in the Discipline (WID) initiatives in undergraduate Studio Art curriculum as a heuristic tool to improve student’s visual art practice and prepare them for graduate-level writing. Scholars involved in Studio Art MFA programs have noted graduate students’ difficulty at adopting writing as a part of their creative practice, but they focus on addressing the issue at the graduate level rather than scaffolding undergraduate curriculum to support students’ transition to upper division writing. This thesis argues that writing instruction should be incorporated into Studio Art undergraduate study to prepare students for careers and further study in the arts while improving their art practice through introspective journaling, research, and revision. This research features assignments and exercises from WAC/WID scholarship that meet the needs of visual art students based on various rhetorical situations, genres, and discourse communities. I included a public writing assignment, reflection exercises, and exphrastic writing as appropriate writing assignments for studio art undergraduates because they allow students to explore their own art within the broader cultural landscape as well as develop their own critical voice as participants in their discourse community.

Show moreAlzheimer’s Disease affects millions of patients throughout the world and has widespread, debilitating impacts on patients and their loved ones.1 Current efforts to study the accumulation of the peptide amyloid-beta in interneural spaces and possible mechanisms of amyloid clearance appear promising for the development of future therapies.2 Several small biomolecules with anti-inflammatory and anti-oxidative properties have been shown to impact the aggregation of amyloid-beta and are thus candidates for future drug development, targeting the amyloidogenic, inflammatory, and oxidative stress components of Alzheimer’s pathology.3-6 This study aims to determine the regions on amyloid-beta to which Vitamin B12 binds using X-ray crystallography and diffraction analysis. Literature reviews were conducted to find optimal solution conditions to solubilize amyloid-beta and previously documented interactions between the two molecules. Buffer screens were then carried out and a buffer was selected for subsequent crystallization trials. Crystals of Vitamin B12 and Vitamin B12 with amyloid-beta were generated via hanging drop vapor-diffusion crystallization. Crystals were diffracted using the AMX-17ID-1 beamline of the National Synchrotron Light Source II at Brookhaven National Laboratory, and a structure was determined from one of our crystals of Vitamin B12 and amyloid-beta. Though no amyloid-beta was observed in the unit cell of Vitamin B12 determined from the sample, significant observed heterogeneity in the unit cell warrants further study of these potential complexes. We are currently pursuing the determination of structures from our remaining crystals and the generation of new samples of amyloid-beta and various other small biomolecules demonstrated to impact amyloid-beta’s aggregation.

Show moreIn my thesis, I propose a new theory of wages as deserved income. I take a look at two prominent philosophers’ discussions on the subject, and find they are both lacking. George Sher believes that desert in wages can best be explained by appealing to the violation of moral standards that dictate how we believe the world should be. He says that, because subordinating our labor to another’s ends (i.e. ‘working’) violates some “independent standard,” wages are deserved to offset this loss of autonomy. A wage is “uniquely suited” to allow a worker to pursue his own goals in turn, says Sher. Joel Feinberg argues that, as far as wages are deserved at all, they are deserved only as compensation for especially difficult, dangerous or unpleasant work, and that they can only explain deserved differentials in pay. He rejects the idea that deserved wages can be explained as a reward. My own theory, briefly, is this: wages are deserved as a reward after a worker has (1) put forth an effort that (2) has been directed toward the end of another and (3) is socially valuable. Finally, I survey the literature in the living wage movement. Finding it lacking in the language of desert, I propose that the proponents of a living wage adopt an argument like mine. That is, I suggest they give to desert a more central role in their discussions about why workers should receive a living wage.

Show moreThe multipotent ability of mesenchymal stem cells (MSC) to differentiate into a large variety of mature cell types gives them a high potential for use in a variety of therapeutic purposes. Recently, it was discovered that bone marrow derived MSC could be induced to take on a neuronal phenotype through the addition of cobalt chloride (CoCl2) to the growth media. It is also well known that the trace element zinc is vital for both neuronal proliferation and differentiation from neuronal precursor cells. Thus, this work tested the hypothesis that zinc plays a role in the differentiation of MSC into neurons. Secondly, because zinc is unable to enter or exit cells without the assistance of zinc transport proteins (ZnT), this work tested the hypothesis that two transport proteins, ZnT-1 and ZnT-4, would be regulated both by zinc and by treatment with cobalt. This work used both cell morphology and markers of neuronal differentiation (TuJ1 and neuronal specific enolase) to show that zinc deficiency (ZD) combined with CoCl2 treatment appeared to induce differentiation of rat MSC. Furthermore, the zinc transporters were differentially regulated such that ZnT-4 was increased on the cell membrane by zinc deficiency, while ZnT-1 levels at the membrane were highest in the combined zinc deficiency-cobalt treatment group. These data implicate zinc in the mechanisms associated with MSC function.

Zymosan is a component the fungal cell wall that induces an innate immune response. After THP1 were treated with zymosan, we hypothesized that the fungal infection would initiate an inflammatory response by altering nucleosome redistribution and/or altering chromatin structure in a time dependent manner. Based on previous results that showed rapid, widespread, transient changes in nucleosome distribution in the innate immune response, we chose to look at multiple time points at high temporal resolution: 0 (control), 20', 40', 60', 80', 100', 2h, 3h, 4h and 12h. We measured nucleosome distribution at each of these time points at hundreds of genes transcription start sites involved in the immune response. nucleosome distribution changes in the innate immune response to fungal infection.

In initial studies, my lab created a knockout of two E3 ubiquitin ligases thought to be essential to the clock, βTRCP1/2, in a mouse model in order to study the proteasomal degradation machinery in mammals. Upon characterizing the circadian phenotype of this mouse, we noticed an unprecedented, metabolic phenotype after deletion of these vital ligases. These novel mutant mice lose over 30% of their body weight within 5 days while still maintaining an eating and drinking regime similar to wild-type mice. In this project, in vivo and sequence analysis studies aimed to look further into the causes of this phenomenon and the molecular mechanisms underlying them.

Show moreA critical consideration in the process of de novo protein architecture design and protein evolution is the folding pathway and behavior a protein undertakes in transitioning to its functional tertiary structure. Of particular interest is a cryptic element within protein primary structure that enables an efficient folding pathway, and is postulated to be a heritable element in the evolution of protein architecture, the "folding nucleus" (FN). However, almost nothing is known regarding how the FN changes as simpler peptide motifs join to form more complex polypeptides. To this effect, the structure and folding properties of foldable intermediates along the evolutionary trajectory of the β-trefoil protein type were tested. This study specifically used and compared data from Symfoil-4T (an engineered β-trefoil protein) to several mutants to show that the FN is acquired during gene fusion events, incorporating novel turn structure generated by gene fusion. Furthermore, the FN of β-trefoils are adjusted by circular permutation in response to destabilizing functional mutations to allow the survival of FN (which is made possible by the intrinsic C3 cyclic symmetry of β-trefoil architecture) identifying a selective advantage that helps explain extant cyclic structural symmetry in the proteome.

Recent literature has demonstrated that if someone studies one list of word pairs followed by another list of word pairs in which the second half of some of the pairs have changed (e.g., they saw “knee-bone” on the first list and “knee-bend” on the second list), this change can remind them of the pair’s presence on the original list and improve memory performance for both of the pairs.

Show moreRecent literature has demonstrated that if someone studies one list of word pairs followed by another list of word pairs in which the second half of some of the pairs have changed (e.g., they saw “knee-bone” on the first list and “knee-bend” on the second list), this change can remind them of the pair’s presence on the original list and improve memory performance for both of the pairs. Previously, this kind of design would lead researchers to observe interference, which would cause memory performance to suffer; the discovery of the memory enhancing effects of reminders inspired further research to understand how their underlying mechanisms and what makes them more likely to occur. The presented research examines whether picture-word pairs will trigger more remindings than word-word pairs on the presumption that the picture superiority effect will play an important role. The results indicate that participants did experience more remindings for the picture-word pairs than for the word-word pairs and that better memory performance for picture-word pairs is due to a combination of this effect and an encoding effect.
