Research Colloquium

Aberrant activation of β-catenin signaling is strongly associated with cancer proliferation, invasion, migration, and metastasis, thus small molecules that can inhibit this pathway might have great clinical significance. Our molecular modeling studies suggest that Ormeloxifene (ORM), a triphenylethylene molecule docks with β-catenin, and its brominated analogue (Br-ORM) bind more effectively with relatively less energy (-7.6 kcal/mol) to the active site of β-catenin as compared to parent ORM. Herein, we report the synthesis and characterization of a Br-ORM by NMR and FTIR, as well as its anti-cancer potential in cervical cancer models in vitro and in vivo. Br-ORM treatment effectively …

The Role Of Med13 In Proteaphagy, John Sauer, Brittany Friedson, Katrina Cooper

Rowan-Virtua Research Day

Regulation of proteasomes is important for adaptation to cellular stress. Previous studies have shown that following starvation stress, proteasomes are targeted for destruction by autophagy. However, how cells control proteasomes in response to nitrogen starvation remains unclear. This study delves into the intricate interplay between Med13, proteaphagy, and stress response regulation, aiming to elucidate their roles in cellular survival mechanisms. It focused on the highly conserved Cdk8 kinase module (CKM) of the Mediator complex a that plays a pivotal involvement in cellular signaling and gene regulation under stress conditions. During the investigation, we asked if the degradation of specific proteasome …

Using Edna To Assess Impacts Of Oyster Restoration On Ecosystem Biodiversity At A Heavily Impacted Coastal Lagoon, Dominique Di Domenico, Emily Bonacchi, Elizabeth Suter

Molloy Multidisciplinary Undergraduate Research Conference

The Great South Bay (GSB), a bar-built, temperate, coastal lagoon on the south shore of Long Island, New York, USA, is a highly modified estuary due to heavy urbanization and suburbanization in the last century. GSB historically provided up to 50% of the nation’s hard clam (Mercenaria mercenaria) harvest, and is the legal home of the “Blue Point” oyster (eastern oyster; Crassostrea virginica). However, due to overexploitation as well as persistent stress from ongoing nitrogen pollution and harmful algal blooms, shellfish populations are fractions of their original abundances. Restoration efforts in GSB, driven both by community efforts …

In Silico Identification Of Small Molecule Agonist Binding Sites On Kcc2, Kenyon Mitchell, Alfred Amendolara, Ruth Hunter, Jaden Miner, Andrew Payne

Annual Research Symposium

Purpose: Potassium-Chloride Cotransporter 2 (KCC2) is a neuronal membrane protein specific to the central nervous system. It is responsible for removing Cl- ions from the intracellular space, maintaining a normal Cl- gradient essential for proper function at inhibitory synapses. Dysregulation causes an upward shift in the Cl- reversal potential resulting in a hyperexcitable state of the postsynaptic neuron. Existing literature indicates that KCC2 may be involved in the addiction pathway of a variety of drugs of abuse, including opioids and alcohol. This makes KCC2 an attractive potential drug target when treating substance use disorders. A novel direct KCC2 agonist, VU0500469, …

A Comparison Of In Vitro Studies Between Cobalt(Iii) And Copper(Ii) Complexes With Thiosemicarbazone Ligands To Treat Triple Negative Breast Cancer, Duaa R. Alajroush, Chloe B. Smith, Brittney F. Anderson, Ifeoluwa T. Oyeyemi, Stephen J. Beebe, Alvin A. Holder

Undergraduate Research Symposium

Triple negative breast cancer (TNBC) is one of the most aggressive forms of breast cancer, and disproportionately affects African American women. TNBC cells lack the common hormone receptors that many pre-existing cancer treatments target. Fortunately, metal-based complexes with thiosemicarbazone ligands have gained significant attention for their potential as anti-cancer agents. Cobalt(III) complex ([Co(phen)2(MeATSC)](NO3)3•1.5H2O•C2H5OH]) and Copper(II) complex ([Cu(acetylethTSC)Cl]Cl•0.25C2H5OH) specifically have properties of high toxicity, which can contribute to decreased cancer cell activity. The effects of these complexes are currently being investigated on cancerous and non-cancerous breast cell lines. The cytotoxic effect of the cobalt(lll) complex and the copper(ll) complex was analyzed …

Research Symposium

Background: Pancreatic cancer, characterized by its high mortality rate, stands as one of the most aggressive cancer forms. The projected surge in pancreatic cancer-related deaths, making it the second leading cause in the United States by 2030, underscores the urgency for effective early screening tools. This study employs data mining methods to scrutinize bioinformatic data surrounding TRIP13. Examining differential expression across various cancers, correlating TRIP13 expression with pancreatic cancer stages, exploring associations with common cancer genes, and analyzing overall survival rates constitute the core investigations. Integrated with molecular biology techniques, the study further quantifies TRIP13 expression in progressive pancreatic cancer …

Targeting Mycobacterial Efflux System For Combating Anti-Microbial Resistance, Arathi Radhakrishnan, Raj Kishor Kapardar, Rajpal Srivastav

Research Symposium

Background: The drug resistance in the microbes is a serious concern in medicine. Along with intrinsic factors, extrinsic factors like unprescribed usage of drugs are the contributing factors. The drug tolerance has led to the emergence of superbugs. Mycobacterial species utilize an array of multidrug efflux mechanisms linked to intrinsic and acquired antibiotic resistance. Understanding molecular mechanisms regulating efflux could reveal new therapeutic targets and strategies. Our study is aimed to target regulators of efflux Mycobacterial transporter.

Methods: Using the reference mycobacterial strain, antibiotic sensitivity was first profiled by minimal inhibitory concentration assays across a panel of antimicrobials, followed by …

Proteomic Analysis Of Stress Associated Factor Overexpression In Hepatocellular Carcinoma, Mohammad Shabir Hussain, Sophia Leslie, Amayrani Sanchez, Samantha Lopez, Kyle Doxtater, Manish Kumar Tripathi

Research Symposium

Background: Hepatocellular carcinoma (HCC) constitutes a substantial portion, accounting for 85% to 90% of liver cancers worldwide. Notably, within the Hispanic population, liver cancer mortality rates are notably higher, particularly evident in regions like the South Texas Rio Grande Valley (RGV), where nearly 90% of the populace is Latino/Hispanic. This region grapples with poverty affecting nearly 30% of its residents, coupled with elevated rates of obesity, diabetes, and low-income households, thereby fostering a prevalent environment of stress. Stress can profoundly impact cancer outcomes by compromising immune functionality and triggering inflammatory responses, potentially impairing surveillance against oncogenic triggers. The activation of …

Piperlongumine Nanoformulation Attenuates Pancreatic Tumor Desmoplasia And Alter Tumor Immune Responses, Vivek Kumar Kashyap, Neeraj Chauhan, Mohammed Sikander, Eswara N. H. K. Ghali, Bilal Hafeez, Murali M. Yallapu, Meena Jaggi, Subhash C. Chauhan

Research Symposium

Pancreatic cancer (PanCa) is characterized by lack of early diagnosis, poor response to available therapeutic modalities and chemoresistance. Gemcitabine (GEM) is currently considered the most effective therapy for PanCa; however, it shows only a marginal survival benefit of 6 months. This poor drug response has been attributed to desmoplasia, causes suboptimal drug delivery, alters tumor microenvironment (TME), which includes tumor surrounding blood vessels, fibroblasts, immune cells, extracellular matrix, and other signaling molecules and induces chemo-resistance in tumors. To overcome these existing issues associated with chemotherapy, identification and development of novel therapeutic modalities are a pressing need. Piperlongumine (PL) is a …
