Characterizing Stiffness Dynamics Of Normal And Malignant Breast Spheroids Using Brillouin Microscopy, Razanne Rafat Zaghloul, Karlin Hilai, Chenjun Shi, Jitao Zhang

Medical Student Research Symposium

Background: Breast cancer progression and metastasis are closely linked to alterations in the mechanical properties of tumor cells and their microenvironment. Softer, more deformable cells are often associated with higher metastatic potential. While atomic force microscopy (AFM) is the current gold standard for mechanical characterization, it is limited to surface measurements and can damage 3D cultures. It remains unclear how the mechanical properties evolve over time in normal versus malignant spheroids. This study utilizes Brillouin light-scattering microscopy, a non-contact and label-free optical technique, to assess stiffness changes in normal and malignant breast epithelial spheroids over time. Understanding these mechanical signatures …

Environmental Mercury Alters Immune Pathways Linked To Autoimmune Risk In Mice Mirroring Humans, Maurgan Lee, Paul Stemmer, Randall Gill, Allen Rosenspire, Anil Aranha, Heather Gibson

Medical Student Research Symposium

Background and Purpose: Mercury is a pervasive environmental contaminant, and human epidemiologic studies have linked chronic low-level exposure to increased autoimmune disease-risk. Dysregulated lymphocyte activation and impaired signaling tolerance are central mechanisms in human autoimmunity. Protein phosphorylation governs lymphocyte differentiation and function, alterations in phosphoproteomic networks may represent a signature of immune disruption. This study evaluates how low dose mercury exposure modifies B and T cell abundance and intracellular signaling patterns in BALB/c and Diversity Outbred (DO) mice.

Methods: BALB/c and DO mice were exposed to low dose HgCl2 in their water for two weeks or provided standard water controls. …

Medical Student Research Symposium

VARIATION IN BARORECEPTOR SENSITIVITY PREVENTS GENERALIZED ANXIETY. Alexander Weaver, Jack Summers, Judy Taha, Zak Miklja, Warren Lockette. Division of Endocrinology, Wayne State University School of Medicine, Detroit, MI.

Key words: anxiety, baroreceptors, cardiovascular disease, PIEZO 1, humans, instantaneous baroreceptor sensitivity

BACKGROUND

We reported ex vivo measurements of PIEZO 1 channel activity in erythrocytes can predict those individuals with high levels of generalized anxiety. Because PIEZO 1 channels are expressed in cardiac baroreceptors, we next tested our hypothesis that contrasts in generalized anxiety in the population could be due to individual differences in PIEZO 1-dependent instantaneous baroreceptor sensitivity.

Medical Student Research Symposium

Background: Avapritinib, a selective inhibitor of mutated class III receptor tyrosine kinases (RTKs), shows promise in PDGFRA-altered pediatric glioma. We studied its efficacy in a glioblastoma (GBM) model (HF3253) containing two PDGFRA alterations: constitutive activation via an indel mutation and extrachromosomal DNA (ecDNA) amplification. We hypothesized that Avapritinib would preferentially improve survival in PDGFRA-amplified tumors.

Methods: Orthotopic xenografts derived from HF3253 PDGFRA ecDNA(+) (n=19) and ecDNA(-) (n=10) cells were treated with 40 mg/kg Avapritinib (5 days/week). To validate the role of PDGFRA expression, wild-type PDGFRA was overexpressed in ecDNA(-) cells, generating high PDGFRA levels with minimal ligand-independent activation in vivo. …

Titanium Dioxide: An Inquiry Into The Mechanisms And Implications Of Exposure In Gut Dysbiosis And Metabolic Disorders, Meghan Gardiner

Senior Honors Theses

Titanium dioxide (TiO₂) is one of the most prevalent food additives utilized in commercial products in the United States. While TiO₂ was originally hailed as a nontoxic and cost-effective additive, studies are beginning to reveal that TiO₂ is not as safe as it once seemed. TiO₂ may contribute to the development of insulin resistance and metabolic disorders through direct and indirect mechanisms. The compound induces gut dysbiosis, leading to alterations in bacterial metabolites and pro-inflammatory cytokines, which results in the selective resistance of glucocorticoid receptors. Additionally, TiO₂ itself can translocate from the gut to …
