Glioblastoma (GB) is one of the deadliest cancers and the most common form of adult primary brain tumors. SGEF (ARHGEF26) has been previously shown to be overexpressed in GB tumors, play a role in cell invasion/migration, and increase temozolomide (TMZ) resistance.[3] It was hypothesized parental LN229 cell lines with SGEF

Glioblastoma (GB) is one of the deadliest cancers and the most common form of adult primary brain tumors. SGEF (ARHGEF26) has been previously shown to be overexpressed in GB tumors, play a role in cell invasion/migration, and increase temozolomide (TMZ) resistance.[3] It was hypothesized parental LN229 cell lines with SGEF knockdown (LN229-SGEFi) will show decreased metabolism in the MTS assay and decreased colony formation in a colony formation assay compared to parental LN229 cells after challenging the two cell lines with TMZ. For WB and co-immunoprecipitation (co-IP), parental LN229 cells with endogenous SGEF and BRCA were expected to interact and stain in the BRCA1:IP WB. LN229-SGEFi cells were expected to show very little SGEF precipitated due to shRNA targeted knockdown of SGEF. In conditions with mutations in the BRCA1 binding site (LN229-SGEFi + AdBRCAm/AdDM), SGEF expression was expected to decrease compared to parental LN229 or LN229-SGEFi cells reconstituted with WT SGEF (LN229-SGEFi + AdWT). LN229 infected with AdSGEF with a mutated nuclear localization signal (LN229-SGEFi + AdNLS12m) were expected to show BRCA and SGEF interaction since whole cell lysates were used for the co-IP. MTS data showed no significant differences in metabolism between the two cell lines at all three time points (3, 5, and 7 days). Western blot analysis was successful at imaging both SGEF and BRCA1 protein bands from whole cell lysate. The CFA showed no significant difference between cell lines after being challenged with 500uM TMZ. The co-IP immunoblot showed staining for BRCA1 and SGEF for all lysate samples, including unexpected lysates such as LN229-SGEFi, LN229-SGEFi + AdBRCAm, and LN229-SGEFi + AdDM. These results suggested either an indirect protein interaction between BRCA1 and SGEF, an additional BRCA binding site not included in the consensus, or possible detection of the translocated SGEF in knockdown cells lines since shRNA cannot enter the nucleus. Further optimization of CO-IP protocol, MTS assay, and CFA will be needed to characterize the SGEF/BRCA1 interaction and its role in cell survival.

The goal of this project was to design and create a genetic construct that would allow for <br/>tumor growth to be induced in the center of the wing imaginal disc of Drosophila larvae, the <br/>R85E08 domain, using a heat shock. The resulting transgene would be combined with other <br/>transgenes in a single fly that would allow for simultaneous expression of the oncogene and, in <br/>the surrounding cells, other genes of interest. This system would help establish Drosophila as a <br/>more versatile and reliable model organism for cancer research. Furthermore, pilot studies were <br/>performed, using elements of the final proposed system, to determine if tumor growth is possible <br/>in the center of the disc, which oncogene produces the best results, and if oncogene expression <br/>induced later in development causes tumor growth. Three different candidate genes were <br/>investigated: RasV12, PvrACT, and Avli.

My project is designed to provide art education to incarcerated youth in Arizona. This project will address two current issues in Arizona; the underfunding of art programs and high rates of incarceration. As of 2021, there are no state-funded art programs in Arizona. Arizona is tied with Texas for the eighth highest rate of incarceration in the country. In Arizona, 750 out of every 100,000 people are incarcerated. This project is an art course for incarcerated youth. The project includes a packet detailing the course content and assignment details, a class syllabus, a course flyer, and a certificate of completion. The course is intended to be taught at the Adobe Mountain School facility. The course is designed so that it can be implemented in other facilities in the future. The class will be taught by volunteers with a background in studio art, design, or art education. Each student will receive a course packet that they can use to keep track of information and assignments. Instructors will use the course packet to teach the class. The course focuses on drawing with charcoal and oil pastel, which will build a foundation in drawing skills. The course covers a twelve-week semester. The course content packet includes a week-by-week breakdown of the teaching material and project descriptions. The course consists of two main projects and preparatory work. The preparatory work includes vocabulary terms, art concepts, drawing guides, brainstorming activities, and drawing activities. The two main prompts are designed for students to explore the materials and to encourage self-reflection. The class is curated so that students can create art in a low-risk, non-judgemental environment. The course will also focus on establishing problem-solving and critical thinking skills through engaging activities.

Many studies have supported the theory that gain-framed messaging is effective in changing smoking behavior. However, the importance of focusing on long-term positive benefits or short-term positive benefits in this messaging remains a mystery. This study investigated the role that reward-delay within gain-framed messaging has on the self-esteem and behavior of cigarette smokers. Specifically, it sought to answer the question of whether short-term reward-delay messaging is more effective in increasing self-esteem and positive smoking behavior than long-term reward-delay messaging. An intervention was conducted in which participants, 16 female and 17 male, were exposed to either short-term reward-delay information or long-term reward-delay information. Self-esteem scores as well as smoking behavior were measured and compared before and after the intervention. Results from the study showed that participants in the short-term reward-delay group smoked 2 less cigarettes per day and 12 less cigarettes per week on average after the intervention than participants in the long-term reward-delay group. The results were also consistent with the findings of previous studies that suggest females are more heavily influenced by gain-framed messaging than males.

Poetry serves as a window through which we can convey emotions and experiences otherwise difficult to access and express. This chapbook addresses the moments in life that have dramatic transformational effects and those moments and events we wish to deny. Through my poetry, I reveal the honest revelations of hurt and pain, and the raw emotions evoked from the things that have occurred throughout my life. In doing so, I confront these painful experiences from a place of conscious awareness of the way in which they have impacted my life, and I allow others access to my hurt, self-hatred, and imperfection acknowledged throughout. This chapbook symbolizes the movement from a place of denial to a place of awareness and finally to a place of transformation and growth. As my poetry transformed from weak poems only accessible on an abstract level to powerful poems of honest and tangible pain and hurt, I experienced my own transformation. Allowing myself to candidly share my experiences with others has enabled me to grow from these experiences.

Scientists, lawyers, and bioethicists have pondered the impact of scientifically deterministic evidence on a judge or jury when deciding the sentence of a criminal. Though the impact may be one that relieves the amount of personal guilt on the part of the criminal, this evidence may also be the very reason that a judge or jury punishes more strongly, suggesting that this type of evidence may be a double-edged sword. 118 participants were shown three films of fictional sentencing hearings. All three films introduced scientifically deterministic evidence, and participants were asked to recommend a prison sentence. Each hearing portrayed a different criminal with different neurological conditions, a different crime, and a different extent of argumentation during closing arguments about the scientifically deterministic evidence. Though the argumentation from the prosecution and the defense did not affect sentencing, the interaction of type of crime and neurological condition did.

Substance abuse disorders affect 15.3 million people worldwide. The field has primarily focused on dopaminergic drugs as treatments for substance use disorders. However, recent work has demonstrated the potential of serotonergic compounds to treat substance abuse. Specifically, the serotonin 1B receptor (5-HT1BR), a Gi-coupled receptor located throughout the mesocorticolimbic dopamine system, has been implicated in the incentive motivational and rewarding effects of cocaine. Our research suggests that the stimulation of 5-HT1BRs produces different effects at various time points in the addiction cycle. During maintenance of chronic cocaine administration, 5-HT1BR stimulation has a facilitative effect on the reinforcing properties of cocaine. However 5-HT1BR stimulation exhibits inhibitory effects on reinforcement during prolonged abstinence from cocaine. The aim of this study was to examine the possibility of a switch in the functional role of 5-HT1BRs in the locomotor effects of cocaine at different time points of chronic cocaine administration in mice. We found that the 5-HT1BR agonist CP 94,253 increased locomotor activity in mice tested one day after the last chronic cocaine administration session regardless of whether the chronic treatment was cocaine or saline and regardless of challenge injection (i.e., cocaine or saline). Yet after abstinence, CP 94,253 induced a decrease in locomotor activity in mice challenged with saline and attenuated cocaine-induced locomotion relative to cocaine challenge after vehicle pretreatment. These findings suggest that a switch in the functional role of 5-HT1BR is observed at different stages of the addiction cycle and further suggest that clinical applications of drugs acting on 5-HT1BR should consider these effects.

Cancer is one of the leading causes of death in the world and represents a tremendous burden on patients, families and societies. S. Typhimurium strains are specifically attracted to compounds produced by cancer cells and could overcome the traditional therapeutic barrier. However, a major problem with using live attenuated Salmonella as anti-cancer agents is their toxicity at the dose required for therapeutic efficacy, but reducing the dose results in diminished efficacy. In this project, we explored novel means to reduce the toxicity of the recombinant attenuated Salmonella by genetically engineering those virulence factors to facilitate maximal colonization of tumor tissues and reduced fitness in normal tissues. We have constructed two sets of Salmonella strains. In the first set, each targeted gene was knocked out by deletion of the gene. In the second set, the predicted promoter region of each gene was replaced with a rhamnose-regulated promoter, which will cease the synthesis of these genes in vivo, a rhamnose-free environment.

There is preclinical evidence that the detrimental cognitive effects of hormone loss can be ameliorated by estrogen therapy (Bimonte, Acosta, & Talboom, 2010), however, one of the primary concerns with current hormone therapies is that they are nonselective, leading to increased risk of breast and endometrial cancers as well as heart disease. Thus, in order to achieve a successful and clinically relevant long-term hormone therapy option, it is optimal to find an estrogen therapy regimen that is selective to its target tissue. Recently, phytoestrogens have been found to exert selective, beneficial effects on cognition and brain. For example, genistein and diadzein produce neuroprotective effects in cognitive brain regions (Zhao, Chen, & Diaz Brinton, 2002). The purpose of this study was threefold: 1) to examine the cognitive impact of phytoestrogens in young ovariectomized rats, 2) to replicate the dose effects found in the Luine study (Luine et al., 2006), while controlling for manufacturer differences, and 3) to assess if the rodent diet used in our laboratory has an estrogenic-like cognitive impact.The current findings suggest that, at least for object memory, diets containing varying amounts of phytoestrogens can alter cognition, with diets containing high amounts of phytoestrogens showing potential benefits to this type of memory.
