Impact Of Ashwagandha Treatment On Cytokine Production And Macrophage Differentiation Into Thp-1 Cells, Betsi Diaz Chavarin, Aditi Kumar

Posters - 2026

Inflammation is a critical biological response that enables the immune system to react to infections, injuries, or stressful situations. However, chronic or excessive inflammation can lead to tissue damage and contribute to a wide range of diseases, including neurodegenerative disorders, metabolic syndromes, and immune dysregulation. 3,4 Interleukin-1 beta (IL-1β) is a key pro-inflammatory cytokine that plays a central role in initiating and amplifying the immune response. 1,2 It is primarily produced by activated monocytes and macrophages in response to stimuli such as pathogens or stress signals. In addition, IL-1β acts on the hypothalamus to induce fever, which creates an environment …

"I Need Help!": Can Ashwagandha Reduce Inflammation-Driven Oxidative Stress Without Inducing Cytotoxicity In Macrophages?, Caitlyn Pinaga

Posters - 2026

Ashwagandha has been shown to reduce inflammation in humans by lowering pro-inflammatory cytokines and oxidative stress markers, helping regulate immune responses. It is commonly used to support conditions linked to chronic inflammation, such as stress-related disorders, arthritis, and metabolic imbalance. THP-1 macrophages are a part of the body's immune response to inflammation. While they produce a lot of different responses to inflammation, one of them is the production of Reactive Oxygen Species (ROS). N-acetylcysteine (NAC) is established to be a powerful antioxidant and is used as a positive control. My study aims to understand how ashwagandha, a popular supplement, affects …

Identifying Rna Splicing Changes During Alcohol Withdrawal Using An Optimized Rna-Seq Analysis Pipeline, Yasaswi Veera, Luana Martins De Carvalho, Amy Lasek

UROP Posters

Alcohol use disorder (AUD) causes long-lasting changes in brain gene expression and RNA splicing, particularly in the ventral hippocampus. This study analyzes RNA-Seq data from rats exposed to chronic alcohol and withdrawal to identify transcript-level and splicing alterations. An optimized RNA-Seq pipeline using STAR, FeatureCounts, edgeR, and WGCNA improved efficiency by 25-40% while maintaining consistency across 25 datasets. Results reveal changes in neural signaling and stress-response pathways associated with withdrawal. This work provides both biological insight into AUD and a reproducible computational framework for transcriptomic analysis.

Selective Gsk3b Overexpression In Medial Prefrontal Cortex Camkiia Cells Produces Sex-Specific Changes In Ethanol Self-Administration, Anxiety-Like Behavior, And Working Memory, Sam Gottlieb, Zachary Tatom, Michael F. Miles

Graduate Research Posters

Background: Glycogen synthase kinase 3 beta (Gsk3b) is central in a gene network regulated by ethanol in mouse medial prefrontal cortex (mPFC). GSK3B abundance/activity modulations regulate ethanol consumption, suggesting GSK3B could be a target in treating alcohol use disorder. However, the critical cell type in this ethanol response is not yet known, nor have sex differences in GSK3B modulations been fully investigated. Here we report results of GSK3B overexpression selectively in CamKIIa⁺ mPFC cells on multiple behaviors.

Methods: Mice underwent stereotaxic injections to overexpress GSK3B in mPFC CamKIIa⁺ cells or control virus (n=4-6/sex/virus). We assayed working …

Influence Of 2,5-Dimethoxy-4-Iodoamphetamine (Doi) On Ethanol Preference And Consumption In C57bl/6 Male Mice, Alaina M. Jaster, Sam Gottlieb, Michael Miles, Javier González-Maeso

Graduate Research Posters

Substance use disorders (SUD) account for a large number of mental health diagnosis in the United States and around the world. Approximately 13.6 million adults 26 or older and 5.1 million young adults (ages 18-24) battled with a SUD in 2017. Alcohol Use Disorder (AUD) alone effects nearly 6% of the adult population within the United States. This creates a substantial burden on the individual, with alcohol being the third-leading cause of preventable death in the United States. Few treatments for AUD exist, with no new FDA-approved therapeutic treatments within the last 15 years. Additionally, the limited treatments we do …

Tip60 Regulation Of Δnp63Α Is Associated With Cisplatin Resistance, Akshay Hira, Andrew Stacy, Jin Zhang, Michael P. Craig, Madhavi Kadakia

Celebration of Undergraduate & Graduate Research, Scholarship, and Creative Activities Materials

About 5.4 million basal and squamous cell skin cancers are diagnosed every year in the US. ΔNp63a, a member of the p53 transcription factor family, is overexpressed in non-melanoma skin cancer and regulates cell survival, migration and invasion. TIP60 is histone acetyltransferase (HAT) which mediates cellular processes such as transcription and the DNA damage response (DDR). Previous studies in our lab have shown that overexpression of TIP60 induces ΔNp63a protein stabilization in a catalytic-dependent manner. Since ΔNp63a is known to transcriptionally regulate several DDR genes and promote cisplatin resistance, its stabilization by TIP60 may contribute to the failure of platinum-based …

The Forensic Characterization Of Bacterial And Fungal Organisms In Traditional Chinese Medicine, Julia Grzymkowski, Christopher J. Ehrhardt, Justin L. Poklis, Michelle R. Peace

UROP Posters

There has been an increase in use of Traditional Chinese Medicine (TCM) in the United States because they are less expensive and believed to be more effective with less adverse effects in comparison to traditional pharmaceutics. Therefore, sales have increased in the US, despite articles and case studies demonstrating the dangers, such as injury and death, related to TCM, stemming from improper labelling, toxic contaminants, and, in some cases, the presence of pathogenic bacteria. The aim of this study was to perform a survival experiment to demonstrate the importance of proper herbal brewing technique and to conduct a molecular and …

Identification Of “Kratom” (Mitragyna Speciosa) Alkaloids In Commercially Available Products, Julia Grzymkowski, Michelle R. Peace, Justin Poklis

UROP Posters

“Kratom” is the common name for the botanical mitragyna speciosa. It is a tree native to Southeast Asia in which leaves contain the psychoactive alkaloids mitragynine and 7-hydroxymitragynine. Kratom is often ingested as teas, chewed, or smoked. It acts as a stimulant in small doses and as an opioid in large doses. Overdoses can result in vomiting, seizures, and death. Recently the Drug Enforcement Agency (DEA) placed Kratom on Schedule 1, but, due to public outcry, it was almost immediately removed.

Eleven kratom based products were obtained from various tobacco shops, “headshops” and via the internet including: Choice brand …
