Children diagnosed with Autism Spectrum Disorder (ASD) often have a challenging time navigating stressful situations. This can be connected to the differences in emotional regulation and sensory processing when compared to children who are neurotypical. Despite the research performed on ASD, there seems to be a gap in understanding how effectively children with ASD are able to reconnect with reality after experiencing an overstimulating environment. To bridge the gap, this study was performed to use advanced eye-tracking technology to gather objective data on key indicators such as facial expressions, pupil dilation, and eye movement patterns. By comparing the responses of …

Investigating Epigenetic Modification As Bio Markers In Ovarian Cancer Cells, Nitya Gourishetty, Anthony Marzouk, Fatimah Hassan M. Alssamani

Undergraduate Student Symposium

Ovarian cancer (OCs) is a one of the leading causes of mortality among gynecological cancers, with approximately 10/100,000 women in the U.S. being diagnosed with the disease. A significant challenge in treating OCs is its inherent resistance to platinum-based chemotherapy drugs, particularly Cisplatin. This study aims to elucidate the mechanisms underlying cisplatin resistance (CR) in ovarian cancer cells by comparing biomarkers of DNA modification between cisplatin-resistant and sensitive ovarian cancer (A2780) cell lines.

Both sensitive and resistant (A2780/A2780-CR) cells were treated with 2 μM of RG-7388, Cisplatin, and CM-272. These drugs are known to act as MDM2 inhibitor, alkylating agent, …

Investigating The Presence And Persistent Organic Pollutants (Pop) In Alaskan Oncorhynchus Keta And Oncorhynchus Kisutch, Christopher Joseph, Srujan Miryala, Alisa Shapsis

Undergraduate Student Symposium

Persistent organic pollutants (POPs) are chemical substances that resist degradation and have a range of adverse effects that have been linked to detrimental health issues in both humans and wildlife. Their introduction into the environment stems from the extensive usage of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) for industrial and agricultural purposes. While their use was banned during the Stockholm Convention in 2004, their presence persists. Since 209 different congeners exist for both PCBs and PBDEs, the primary aim of this project is to identify the types and concentrations of POPs present in Chum salmon (Oncorhynchus keta …

Investigating The Role Of Dnmt Inhibitor Cm-272 Through P21-Mediated Apoptosis In Sk-N-Sh Neuroblastoma Cells, Sruthika Talanki, Sneha Subhash

Undergraduate Student Symposium

Neuroblastoma is a pediatric malignancy originating from neural crest cells, which can manifest the disease anywhere along the sympathetic nervous system. Evidence suggests that epigenetic modifications may trigger cell cycle arrest and induce apoptosis, providing a potential therapeutic avenue for such cancers.

This study investigates whether CM-272, a DNMT-1 inhibitor, promotes histone acetylation and upregulates p21 through a p53-independent pathway, ultimately triggering cell cycle arrest and apoptosis cell death via caspase-mediated mechanisms in SK-N-SH cells. To assess the effects of CM272, we conducted qRT-PCR to evaluate the DNMT-1 gene expression levels and performed western blot analyses to examine key proteins, …

Investigating The Structural And Functional Roles Of Transcriptionally Active Rice Transposons, Eimaan Ahmad, Leelakrishna Angadala, Udhay Nallapati, Rushil Mehrotra, Braham Dhillon Ph.D.

Undergraduate Student Symposium

Transposable elements (TES) are notorious given their contributions to genome dynamics, evolution, gene structure, and regulation of gene expression. Famously once branded as 'junk DNA', TEs are now known to play significant roles in genome structure and function. Plethora of data generated from sequencing projects have advanced the study of transposons but their large size-often larger than read lengths of most sequencing platforms- has limited TE research due to limited coverages in sequenced datasets. Additionally, high copy number of TEs and high sequence similarity-often greater than 80%- between multiple copies of a TE family may lead to erroneous and misguided …

Ketogenic Diet Improves Cognitive Function And Hippocampal Neurogenesis While Reducing Amyloid Pathology In The Tg-Swdi Mouse Model Of Dementia, Victoria Pulido-Correa, Ariana Hernandez, Eleanor J. Wind, Yingying Zhu, Chana Vogel, Shaina Binu, Mikayla Jeneske, Dylan Kurni, Vedika Chidiruppa, Bianca Echeverria

Undergraduate Student Symposium

Cerebral amyloid angiopathy (CAA), characterized by amyloid buildup in cerebral blood vessels, is highly comorbid with Alzheimer's disease (AD) and, on its own, increases the risk of stroke, cognitive impairment, and dementia. Despite its high incidence, no FDA-approved treatments currently exist to treat or prevent this condition. The ketogenic diet (KD), which is high in fats and low in carbohydrates, has shown promise for its therapeutic potential in patients with neurodegenerative diseases, including Alzheimer's. Studies in AD rodent models have found that KD and/or ketogenic supplements attenuate cognitive-behavioral impairments, neuroinflammation, and amyloid pathology. However, its effects on CAA remain unclear. …

Lower Extremity Kinematics And Injury Risk In Collegiate Cross-Country Runners, Arizel Sosa, Hope Laughlin

Undergraduate Student Symposium

Faulty stance-phase running kinematics such as decreased knee flexion (KFLEX) and excessive hip adduction (HADD), contralateral pelvis drop (CPD), and trunk lean (TL) have been linked to running related injuries (RRI) in recreational distance runners. Less is known about collegiate runners who typically have higher and more uniform training volumes. Thus, the study purpose was to prospectively determine if select kinematics could identify RRI risk in collegiate NCAA Division II runners. We conducted laboratory-based 3D biomechanical analyses of 22 runners (sex, 17♀, 5♂; age, 18-25 yrs; height, 1.7±0.1 m; mass, 60.4±8.9 kg) at their competitive season start and tracked RRI …

Approximately, 1.63 million students in the United States (ages 11-18) use vapes, reflecting a concerning trend of nicotine dependence among adolescents. Activation of the nicotine acetylcholine receptor (nAChR) can modulate the dopamine pathways in the mesolimbic system, increasing nicotine addictive behavior. A 3-D printed molecular model was prepared using the PDB file 6PV7, to explore the molecular dynamics of one of the binding sites between subunits A and B of the pentameric receptor. This model highlights the binding of two …

Methyl Group Substituent Effect On The Basicity Of Meso-Substituted Porphyrins, Krisha Patel, Rochelle Avezki, Tej Chaudhari, Alex Arshavsky

Undergraduate Student Symposium

Titration studies of three freebase porphyrins (meso-tetra-2-methylphenyl, meso-tetra-3-methylphenyl, meso-tetra-4-methylphenyl) were carried out to determine the corresponding basicity in solution with a nonpolar solvent (toluene). The differences in the porphyrin structure lie within the position of the substituents, specifically the position of the methyl group. In each trial, protonation of the porphyrins was reached through the repeated addition of trifluoroacetic acid (TFA). In examining the protonation of these different isomers, the pKa values were determined through a spectrophotometric analysis. The apparent pKa values were found using the modified Henderson-Hasselbalch equation.

Parasites In Flight: Toxoplasma Gondii Genotypes In South Florida Birds, Ava Barrasso, Katherine Hirt, Kaitlin Whalen, Shree Diora, Adhiraj Katoch, Aansi Patel

Undergraduate Student Symposium

Toxoplasma gondii is a zoonotic parasite that significantly impacts human and wildlife health. Often associated with domestic cats, avian hosts also contribute to the parasite's persistence in global ecosystems. This research investigates the strain diversity of T. gondii found within South Florida birds. Florida is an avian biodiversity hotspot along two migratory flyways and therefore presents unique opportunities to detect novel and/or virulent genotypes that may present health risks to humans. These risks are increasing with environmental factors (e.g. urbanization and climate change) that facilitate pathogen transmission between feral and domesticated animals, and susceptible human populations. Our approach consists of …

Pecking At Protozoan Parasites: Pcr Diagnostics Of Toxoplasma Gondii In South Floridian Birds, Senia Bu, Donna Huynh, Sridevi Gundimeda, Samhita Doranala, Madeline Hsu, Valentina Cevallos

Undergraduate Student Symposium

Toxoplasma gondii is a protozoan parasite whose prevalence and transmission remain underexplored in wildlife, especially in birds. This is a crucial gap since birds can serve as pathogen reservoirs (facilitating transmission to humans and other animals) and because T. gondii’s prevalence in wildlife (e.g. birds) helps illuminate its environmental distribution. Thus, characterizing T. gondii in local avian communities can help us assess and mitigate risks to the health of humans, pets, agricultural animals, and endangered wildlife. This study investigates T. gondii prevalence in South Florida’s diverse avian species. We obtained tissue samples from >100 birds by dissecting carcasses provided …

Undergraduate Student Symposium

Persistent organic pollutants (POPs) are toxins that bioaccumulate in the environment and are resistant to degradation. Of the POPs, there are 209 congeners each of either polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), contributing to human detriment and dysfunction to vital organs in the human body. Individual POPs have been completely banned by the 2004 Stockholm Convention on Persistent Organic Pollutants, however, levels have remained consistent over the years. The pink salmon (Oncorhynchus gorbuscha) samples used in this study are acquired from three different river locations: Hilda Creek, Salmon River, and Sheep Creek. Hilda Creek is in …

Photodynamic Inactivation (Pdi) Of Microorganisms With Copper Meso-Pyridyl Porphyrin Isomers, Dylan Mavlyanov, Sanjana Sivaiah, Andrew Siedlecki, Rohan Reddy, Andersen Cheong

Undergraduate Student Symposium

Photodynamic Inactivation (PDI) is an antimicrobial approach, independent of antibiotic resistance, that targets pathogens utilizing light and photosensitizers in the presence of oxygen. The growing international concern for the rise in drug-resistant microorganisms has driven research to determine approaches that will keep microbes from developing further immunological adaptations. Photosensitizers are molecules activated by light that produce reactive oxygen species (ROS) lysing and causing cell death in structures of microbes and in diseased mammalian cells. The photosensitizers applied in this experiment are meso–Tetra(N–methyl–pyridyl)porphine tetrachloride isomers. Three variations of the nitrogen placement were used to understand the interactions with the bacterial cell …

Playing Stereoscopic Video Games Enhances The Precision But Not The Accuracy Of Depth Perception, Charlene Li, Nada Bleibel, Lara Cereminati, Yingzi Luo, Betty Z. Li Ph.D., Dennis M. Levi Ph.D., Sandy W. Chat

Undergraduate Student Symposium

Purpose. We recently reported that playing immersive video games in a three-dimensions (3D) environment boosts stereo vision in young adults with normal vision. Here we asked whether the improvement in stereoscopic acuity (precision) was the result of a reduced disparity pedestal, as indicated by a decreased subjective depth bias (accuracy).

Methods. Twenty-one university students with normal visual acuity and stereoacuity were recruited. All of them had limited previous video game experience, and none had ever played 3D video games. Participants were required to play stereoscopic 3D video games for a total of 40 hours, 2 hours per session, over 4-5 …

Predictive Toxicological Analysis Of Novel Prostate Cancer Drug, Dani Sheil

Undergraduate Student Symposium

Prostate cancer is the second-leading cause of cancer-related death in men in the United States, claiming approximately 1 in 44 lives. While novel cancer therapies aim to selectively target cancer cells, minimizing damage to healthy tissues, these treatments can still cause significant side effects. The drug discovery process remains costly and time-intensive, with only 10-20% of compounds making it from clinical trials to market, often due to toxicity issues that arise during later-stage testing. To address this, computational methods in predictive toxicology can expedite drug development by assessing potential toxic effects early, reducing costs and risks. In this study, we …

Psychedelic Substituted Phenethylamine Alters Human Neural Progenitor Cell Morphology, Proliferation, And Survival, Omar E. Saleh, Grace K. Wong, Chase A. Gonzales, Mark Apterman, Laury Pierre, Stacey Doret, Isaac Hai, Travis J.A. Craddock

Undergraduate Student Symposium

Examining how psychedelic substituted phenethylamines affect neural plasticity is key to understanding harms and potential medical implications of recreational drugs. The microtubule cytoskeleton has been proposed to modulate the effects of phenethylamines as a downstream effector and through scaffolding mechanisms. Microtubules play a crucial role in neurite outgrowth, protein transport, and synaptic stability in cells. Our group has shown that specific psychedelic substituted phenethylamines (25B-NBF, 25C-NBF, and DMBMPP) alter microtubule formation in a dose-dependent manner. As these phenethylamines limit microtubule capacities, they may impact cytoskeletal-mediated neural plasticity. This study’s purpose is to determine if substituted phenethylamines, 25B-NBF, 25C-NBF, and DMBMPP …

Reproductive Outcomes In A Mouse Model Of Alzheimer's Disease, Melanie Mendonca, Esperanza Barrios, Chana Vogel, Victoria Pulido-Correa

Undergraduate Student Symposium

Alzheimer’s disease (AD) is a devastating neurodegenerative disease lacking effective treatment. Despite women having 2x greater risk for developing AD, few studies have investigated the sex-specific factors that influence AD risk. Reports show a difference in the risk and progression of AD in parents and nonparents, suggesting motherhood may mitigate the risk and impacts of AD, but alternative explanations could play a role. For example, healthier and wealthier people may have more reproductive opportunities and less disease risk. Moreover, genes that alter disease risk could also modify fertility/fecundity, such as APOE4, a gene that increases both AD risk and fertility. …

Seizure Vulnerability In A C. Elegans Obesity Model, Carina Pavlov, Jeremy Ignatius, Scarlet Jinhong Park Ph.D.

Undergraduate Student Symposium

Metabolic disorders such as diabetes mellitus, characterized by hyperglycemia due to defects in insulin secretion, affect millions of people and increasingly more. Epidemiological studies have shown that individuals with diabetes have a higher risk of developing epilepsy, a neurological disorder where recurrent seizures occur. Conversely, many antiepileptics affect glucose and lipid metabolism.

The nematode Caenorhabditis elegans (C. elegans) is a model organism suited for studying metabolic and neurological disorders, due to its genetic tractability, short life cycle, and conserved signaling pathways. Although previous studies have developed and used genetic and diet-induced obesity models in C. elegans, none …

Sgi-1027 Small Molecule Inhibits Dnmt And Promotes P21-Mediated Apoptosis Via Epigenetic Alterations In Sk-N-Sh Neuroblastoma Cells, Sadhna Seth, Anika Singh, Shyam Sundar Jaganathan Ph.D.

Undergraduate Student Symposium

Neuroblastoma is an aggressive childhood cancer originating from neural crest cells. Treatment for high-risk neuroblastoma includes chemotherapy. Emerging evidence indicates that DNMT inhibitor codenamed SGI-1027 may facilitate cell cycle arrest and induce apoptosis by modulating cell cycle regulatory pathways. Therefore, we hypothesize that SGI-1027 treatment could lead to apoptosis mediated cell death in SK-N-SH cells through the upregulation of p21 transcription.

This study investigated whether SGI-1027, a DNA methyltransferase inhibitor, causes DNA methylation and upregulation of p21 through a p53-independent pathway, which could lead to cell cycle arrest and intrinsic-pathway mediated apoptosis in SK-N-SH cells. To assess the effects of …
