The inferior colliculus is a nucleus in the auditory midbrain that plays an important role in sound and speech processing through how it encodes temporal precision. Temporal precision depends on the balance of inhibition and excitation within the IC. This balance degrades during aging. Age-related changes in synapses have been described in the lemniscal IC as a contributing factor for this imbalance. However, it is unknown if aging affects synapses throughout the non-lemniscal IC in a similar manner. We sought to determine this by examining the dorsal cortex of the IC. The ICd is a non-lemniscal nucleus that is well …


Manuka Honey Modulates Oxidative Stress In Neuro2-A Cells Through Mitochondrial Regulation, Rachel Abramovici Jan 2026

Manuka Honey Modulates Oxidative Stress In Neuro2-A Cells Through Mitochondrial Regulation, Rachel Abramovici

Honors Undergraduate Theses

Manuka honey is known for its vital usage in wound healing, being an agonist towards fighting infections, and is an acting antioxidant [32]. Its main constituents are flavonoids and phenolic compounds, with methyl syringate (MSYR) being a major active ingredient. The specific compounds responsible for these antioxidant effects, particularly in the CNS, remain unclear. It is hypothesized that pre-treatment of mouse neuroblastoma cells with MSYR followed by hydrogen peroxide exposure will activate the AMPK/SIRT1/PGC-1a pathway, due to MSYR’s phenolic structure, and thus reduce oxidative stress and improve mitochondrial biogenesis. Hydrogen peroxide is a standard reactive oxygen species (ROS) treatment to …


Bodies Of Knowledge: The Accuracy Of Medical Anatomical Drawings From The 14th To The 18th Century, Marina G. Mitchell Jan 2026

Bodies Of Knowledge: The Accuracy Of Medical Anatomical Drawings From The 14th To The 18th Century, Marina G. Mitchell

Honors Undergraduate Theses

From the fourteenth to the eighteenth centuries, European anatomical illustration underwent major transformations in response to changing scientific methods, technologies, and visual conventions, reflecting critical transitions in anatomical history. Scientific evolution allowed these images to achieve increasing structural precision and internal detail, though they frequently diverged from anatomical forms as they are understood today. This study examines how anatomical inaccuracies across five centuries emerged not from ignorance, but from deliberate mediation between purpose, observation, pedagogy, artistic convention, and cultural ideology. Through close analysis of works in visual comparison to their modern counterparts, this thesis identifies specific deviations from the twenty-first …


Impact Of Senescence On Breast Cancer Outcomes, Gracie Sous Jan 2026

Impact Of Senescence On Breast Cancer Outcomes, Gracie Sous

Honors Undergraduate Theses

Cellular senescence is a biological process in which damaged cells exit the cell cycle while remaining metabolically active and accumulating within tissues. Senescence plays a complex role in breast cancer progression, largely through the secretion of senescence-associated secretory phenotype (SASP) factors. These factors include a broad range of inflammatory cytokines, chemokines, and signaling molecules that can influence the tumor microenvironment.

Studies suggest that senescence may significantly promote cancer metastasis. Therefore, this study aims to investigate the genes involved in cancer progression and to improve understanding of how SASP is regulated, which is critical for improving breast cancer outcomes. The central …

Hernandez, Ramadevi Subramani, Rajkumar Lakshmanaswamy, Klaus J. Nickisch, Surinder K. Batra, Hareesh B. Nair

Journal Articles: Biochemistry & Molecular Biology

Endometriosis is a chronic, estrogen-dependent inflammatory disease that, despite its benign histology, displays several cancer-relevant features, including clonal expansion, somatic alteration-associated lesion evolution, tissue invasion, apoptosis resistance, immune evasion, angiogenesis, fibrosis, and metabolic adaptation. These features are particularly important in ovarian endometriosis, where recurrent hemorrhage, iron-driven oxidative stress, and chronic inflammatory remodeling may promote malignant transformation. This review examines endometriosis through an oncologic framework by integrating current evidence on disease initiation, clonal lesion evolution, and the peritoneal, ovarian, and deep-infiltrating microenvironments. We discuss how epithelial, stromal, immune, endothelial, mesothelial, and neural components cooperate to support lesion survival, dissemination, vascularization, fibrosis, …

Pancreatic cancer (PC) is a highly aggressive malignancy, with cancer stem cells (CSCs) playing a critical role in metastasis, therapy resistance, and recurrence, thereby presenting significant treatment challenges. Emerging evidence suggests that normal embryonic and adult progenitor stem cells share common gene signatures with CSCs. However, the early pluripotency-associated factors and stemness programs that become aberrantly reactivated during oncogenic transformation remain poorly defined. Here, we identify SLC22A3/OCT3 (Solute Carrier Family 22 Member 3) as a reactivated embryonic-associated signature that regulates PC stemness. SLC22A3 is markedly upregulated in CSC-enriched populations, and its silencing in PC cells grown in both 2D cultures …

Rac1 Gtpase Regulates The Scfβtrcp-Mediated Degradation Of Claspin And The Cellular Response Of Pancreatic Cancer Cells To Gamma Rays, Neha Chaudhary, Tabbatha N. Somers, Surinder K. Batra, Ying Yan, Michel M. Ouellette

Journal Articles: Biochemistry & Molecular Biology

BACKGROUND/OBJECTIVES: Pancreatic ductal adenocarcinomas (PDACs) are lethal tumors exhibiting resistance to most cancer therapeutics, particularly DNA-damaging agents. The

METHODS: Western blot analyses were used to assess the impacts of Rac1 inhibition on the components of the ATR/Chk1 cascade.

RESULTS: Here, we show that Rac1 inhibition disrupts ATR/Chk1 signaling by promoting degradation of Claspin, a key component of the fork protection complex needed for the Ser345-phosphorylation of Chk1 by ATR. In PDACs and normal pancreatic ductal cells, Rac1 inhibition (via inhibitors or siRNA) decreased Claspin protein levels without affecting its mRNA, reflecting a >3-fold reduction in Claspin's half-life. Claspin contains a …

The Underexplored Complexity Of Pancreatic Cancer: Early Dissemination And Quiescence, Nivedeta Krishna Kumar, Annant Bir Kaur, Surinder K. Batra, Moorthy P. Ponnusamy

Journal Articles: Biochemistry & Molecular Biology

Pancreatic cancer has been renowned for its aggressive nature and occasionally manifests periods of dormancy, presenting a perplexing challenge in studying disease progression. Despite surgery, many patients relapse due to dormancy and chemoresistance, resulting in recurrence and death within a few years. Studies also suggest that pancreatic cancer disseminates early on, spreading to secondary organs with no evidence of disease. The lingering question is: how, where, and when does pancreatic cancer recur and spread? Herein, we explore evidence for clinically dormant pancreatic cancer cells, examining the roles of quiescence and stemness populations and their interactions with the tumor microenvironment. Understanding …

Journal Articles: Biochemistry & Molecular Biology

Pancreatic cancer (PC) is characterized by extensive desmoplasia, with heterogeneous cancer-associated fibroblasts (CAFs) as a major component. However, the contribution of distinct precursor cells to CAF heterogeneity remains poorly defined. This study investigated the role of Muc5ac in modulating CAF heterogeneity by maturing precursor cells, including adipose-derived mesenchymal stem cells (AD-MSCs), bone marrow-derived MSCs (BM-MSCs), and pancreatic stellate cells (PSCs), into different CAF subsets. RNA sequencing of precursor cells treated with conditioned media from Muc5ac-proficient or -deficient cancer cells revealed distinct transcriptional profiles. Muc5ac significantly modulated the expression of Dnmts and Tets in AD-MSCs, promoting the acquisition of extracellular matrix …

Overcoming Radiation Resistance: Ferroptosis Induction To Sensitize Solid Tumors To Radiation Therapy, Joseph Carmicheal, Caden M. Fritson, Alexandra Seas, Heidi M. Vieira, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

Radiation therapy (RT) is a mainstay of treatment for a myriad of cancers, often utilized for tumors that are unable to be resected, as well as an adjunct to surgery and chemotherapy. Unfortunately, many cancers are resistant to RT-induced damage and subsequent cell death. This has spurred the pursuit of novel radiation sensitizers that could potentiate the effects of this widely used and important treatment modality. Since its discovery as a regulated cell death mechanism in 2012, ferroptosis has been studied for its connection to cancer and other known oxidative pathways. With this, the interplay between RT and ferroptosis in …

Endothelin-1 In The Failing Fontan: Pathobiology, Precision Therapeutics, And Future Trial Design, Iman Maiza Jan 2026

Endothelin-1 In The Failing Fontan: Pathobiology, Precision Therapeutics, And Future Trial Design, Iman Maiza

Department of Pediatrics Faculty Publications

The Fontan circulation, devised as definitive palliation for single-ventricle congenital heart disease, imposes systemic venous hypertension, loss of pulmonary arterial pulsatility, and restricted preload reserve. These hemodynamic trade-offs progressively injure the pulmonary vasculature, liver, and lymphatic system, producing late morbidities including elevated pulmonary vascular resistance, Fontan-associated liver disease (FALD), protein-losing enteropathy, and arrhythmias. Endothelin-1 (ET-1), a potent vasoconstrictor and profibrotic mediator, plausibly unifies these complications. Mechanistic studies demonstrate ET-1 upregulation in failed Fontan lungs, activating PLC–Ca²⁺, RhoA/ROCK, and MAPK/ERK cascades to drive vasoconstriction and remodeling. In cirrhotic livers, ET-1 localizes to stellate cells, promoting contraction and fibrogenesis, mechanisms biologically relevant …

Nightmares have been shown to be associated with numerous forms of psychopathology, but the vast majority of this research has taken place in the general population and very little is known about their relation with psychopathology in those requiring inpatient hospitalization. In a sample of 1170 voluntarily admitted psychiatric inpatients, this study explores the frequency of reported nightmares in psychiatric inpatients with the aim of examining the prevalence of psychiatric diagnosis in those with and without clinically relevant nightmares. Participants completed the Disturbing Dream and Nightmare Severity Index (DDNSI) and the Structured Clinical Interview for DSM Disorders (SCID-5) at admission. …

Female reproductive aging is characterized by progressive deterioration of ovarian function, yet the molecular mechanisms driving these changes remain incompletely understood. Here, we used long-read direct RNA-sequencing to map transcript isoform changes in mouse ovaries across reproductive age. Comparing young and aged mice after controlled gonadotropin stimulation, we identified widespread alternative splicing changes, including shifts in exon usage, splice site selection, and transcript boundaries. Aged ovaries exhibited increased isoform diversity, favoring distal start and end sites, and a significant rise in exon skipping and intron retention events. Many of these age-biased splicing events altered open reading frames, introduced premature stop …
