Bullying scenarios become more common at a similar time where peer relationships become more important in the daily lives of students as they begin to spend more time interacting with their peers. Positive peer relationships have been associated with positive outcomes for students and thus may serve …

The Glutamine-Asparagine Interplay: Exploring The Role Of Asparagine Synthetase In Hepatocellular Cancer Cells, Babatunde George Olawuni

Graduate Research Theses & Dissertations

Hepatocellular Carcinoma (HCC) is a liver cancer that accounts for a significant proportion of cancer-related deaths globally; likewise, as the primary metabolic regulatory center in the body, the liver undergoes profound metabolic shifts in carcinogenesis, with net glucose and glutamine consumption. Much attention has been focused on the myriad roles of glutamine in supporting cellular growth over the past several decades, but more recently, the relationship between glutamine and the other amide-bearing amino acid, asparagine, has garnered attention. Asparagine is synthesized from glutamine, aspartic acid, and ATP via the enzyme Asparagine Synthetase (ASNS). Extracellular asparagine reliance has been targeted in …

Race-Based Stressors And Racial Trauma: The Moderating Role Of Parental Racial Socialization, Jessica S. Philip

Graduate Research Theses & Dissertations

Experiences of race-based stressors are linked with worse psychological outcomes for racial/ethnic minority individuals (e.g., Ferdinand et al., 2015). The way in which parents talk to their children about race (i.e., racial/ethnic socialization; RES) may exacerbate or buffer against the strength of this link (e.g., Keum & Ahn, 2021). Therefore, the present study examined the links between race-based stressors, RES, and psychological outcomes (i.e., depression, anxiety, stress, racial trauma) across multiple racial/ethnic minority groups. The present study also explored the different RES messages as potential moderators for the link between race-based stressors and outcomes, as well as differences in these …
