Affinity-Optimized Trop2 Antibodies Support Potent Antitumor Activity In Antibody-Drug Conjugates, Aiko Yamaguchi, Junping Hong, Leike Li, Kiyotaka Kobayashi, Chisato M Yamazaki, Summer Y Y Ha, Yasuaki Anami, Wei Xiong, Junquan Liu, Zhiqiang An, Ningyan Zhang, Kyoji Tsuchikama

The Brown Foundation: Institute of Molecular Medicine

Background: Trophoblast cell surface antigen 2 (TROP2) is frequently overexpressed in epithelial tumors and is associated with poor prognosis, making it an attractive therapeutic target. Antibody-drug conjugates (ADCs) directed against TROP2 show clinical benefit, but expression in normal tissues such as skin raises concerns about on-target, off-tumor toxicity. Strategies that improve antitumor efficacy without increasing toxicity are needed.

Methods: Using an in-house phage library, we identified and characterized a novel fully human monoclonal antibody recognizing a unique conformational epitope of TROP2 with reduced binding affinity. This antibody was engineered into homogeneous ADCs carrying auristatin and/or duocarmycin payloads. Comparative studies with …

Telomerase Knockout In Myeloid Cells Predisposes Mice To Foam Cell Formation, Dyslipidemia, Lung Fibrosis, And Cardiac Dysfunction, Zhanguo Gao, Yongmei Yu, David Wiggins, Eva M Sevick-Muraca, Mikhail G Kolonin

The Brown Foundation: Institute of Molecular Medicine

Aging-associated changes in myeloid cells are incompletely understood. One of the culprits of aging is the downregulation of the Tert gene coding for the catalytic subunit of telomerase. Studies of mouse models with Tert knockout (KO) in specific cells have revealed the importance of the telomere-independent noncanonical function of TERT in supporting mitochondrial metabolism and protection from cell senescence. To investigate the role of TERT in myeloid cells (MCs), we analyzed mice with Tert KO in the LysM+ lineage, indelibly labeled with membrane green fluorescent protein (mG). Macrophage numbers and properties in various organs were compared. Changes in the vasculature, …

Tfeb Degradation Is Regulated By An Ikk/Β-Trcp2 Phosphorylation-Ubiquitination Cascade, Yan Xiong, Jaiprakash Sharma, Meggie N Young, Wen Xiong, Ali Jazayeri, Karl F Poncha, Ma Xenia G Ilagan, Qing Wang, Bei Gao, Hui Zheng, Nicolas L Young, Marco Sardiello

Center on Aging Staff Publications

Transcription factor EB (TFEB) is a master regulator of lysosomal biogenesis and cellular clearance pathways. TFEB activity is tightly controlled by multiple post-translational mechanisms, but the exact molecular mechanism controlling its stability has remained elusive. Here, we identify the IκB kinase (IKK) complex as a key regulator of TFEB protein stability through a phosphorylation-ubiquitination cascade. A high-content kinase inhibitor screen reveals that IKK inhibition increases TFEB protein levels, and genetic ablation of IKK components increases TFEB stability, upregulates lysosomal genes, and enhances lysosomal biogenesis and degradative capacity. Mechanistically, we show that IKK phosphorylates TFEB on a cluster of serine residues …

Double-Crispr Knockout Simulation (Dkosim): A Monte-Carlo Randomization System To Model Cell Growth Behavior And Infer The Optimal Library Design For Growth-Based Double Knockout Screens, Yue Gu, Traver Hart, Luis Leon-Novelo, John Paul Shen

Faculty, Staff and Student Publications

Advances in functional genomic technology, notably CRISPR using Cas9 or Cas12, now allow for large-scale double perturbation screens in which pairs of genes are inactivated, allowing for the experimental detection of genetic interactions (GIs). However, as it is not possible to validate GIs in high-throughput, there is no gold standard dataset where true interactions are known. Hence, we constructed a Double-CRISPR Knockout Simulation (DKOsim), which allows users to reproducibly generate synthetic simulation data where the single gene fitness effect of each gene and the interaction of each gene pair can be specified by the investigator. We adapted Monte-Carlo randomization methods …

Feeling Like A Woman: Interoception And The Objectified Body, Tomi-Ann Roberts, James W. Pennebaker, Benita Jackson

Psychology: Faculty Publications

Much of the interoception literature assumes that people can accurately detect their heart rate, stomach contractility, muscle tension, and other biological cues. This is not true. Instead, interoception is an active integrative psychological process where the feeling of one’s internal state emerges from physiological signals, contextual cues, and the social and cultural experiences of living in a body. Thinking of interoception this way shifts the focus from measuring accuracy at detecting biological signaling to studying lived experience. One such experience is the widespread objectification of women’s bodies. Living in a body that is chronically evaluated creates a particular form of …

Informed Consent In Childbirth: A Global Scoping Review Of Episiotomy Practices And The Gaps In U.S. Perinatal Care, Rachel Gulczinski

Senior Theses

Informed consent is a fundamental ethical and legal component of preoperative and perinatal care and forms the foundation of trust between patients and healthcare providers. Despite this, current evidence suggests that many childbirth interventions, including episiotomies, are often performed without explicit patient consent. Episiotomy remains one of the most commonly cited interventions associated with non-consented care and obstetric violence. Therefore, this global scoping review aimed to evaluate whether informed consent is obtained for episiotomy procedures during childbirth, understand documented experiences of disrespect and unnecessary procedures, and identify differences between international and U.S. practices. This thesis followed the PRISMA Scoping Review …

A Review Of Yellow Fever: Epidemiology, Pathogenesis, Clinical Manifestations, Treatment, Prevention, And Prognosis, Farah Ebrahim, Samina Somji, Reena Shah, Salim Surani

Internal Medicine, East Africa

Yellow fever is a mosquito-borne viral illness caused by the yellow fever virus (YFV), a member of the Flaviviridae family. Despite the availability of an effective live-attenuated vaccine, the disease remains endemic in regions of Africa and South America. Transmission occurs primarily via an infected mosquito called Aedes aegypti, with distinct urban, sylvatic, and intermediate transmission cycles. Clinically, infection ranges from mild febrile illness to severe disease, which is characterized by jaundice, hemorrhage, and multiorgan failure. Pathogenesis involves viral replication in hepatocytes, immune-mediated injury, and dysregulated inflammatory responses, leading to characteristic hepatic mid-zone necrosis. Diagnosis relies on molecular detection …

Glioblastoma Multiforme: A Pathologic Breakdown Of One Of Neuro-Oncology's Greatest Challenges, Rosemary Westphal, Ms

Student Papers, Posters & Projects

Glioblastoma multiforme is the most common adult primary tumor with a grim median survival time of 14.6 months. It is characterized by rapid progression, diffuse infiltration, and rather poor clinical outcomes. The WHO classifies GBM as a grade 4 diffuse astrocytic tumor with distinctive histopathological features including high mitotic activity, marked cellular atypia, microvascular proliferation, and necrosis. Advances in molecular diagnostics have further classified GMB into IDH-wild type and IDH-mutant subtypes, with important therapeutic and prognostic implications. Key genetic alterations, such as EGFR amplification, PTEN loss, TP53 mutations, TERT promoter mutations, and MGMT methylations, have been identified as contributing to …

Computed Tomography For Four-Dimensional Dose Calculation: Effect Of Detector Array Length, Inhwan Yeo, Qianyi Xu

Department of Radiation Oncology Faculty Papers

PURPOSE: Four-dimensional computed tomography (4DCT) is susceptible to a geometrical error when respiration changes upon patient shift. 4DCT using 16-cm detector arrays, not needing the shift, has been shown to improve geometrical accuracy, compared with a conventional 4DCT (4-cm array), albeit with some Hounsfield unit discrepancies. The 4DCTs were validated for 4D planning.

MATERIALS AND METHODS: A lung-mimicking phantom containing a spherical target with ten respiratory traces and three tumor-shaped targets with their traces was respectively imaged when, to each of the ten-positions/phases, the lung was moved (1) step-wisely by helical scan at each movement (ground truth; 4DCT_GT), …

The objective of the study was to use SEM to map the influence of different etiological clusters on obesity in childhood.

METHODS: Secondary analysis of baseline data from patients and parents enrolled in a multi-site study of pediatric weight management was conducted. The primary outcome was weight status (utilizing percentage above the 95th percentile BMI, %95BMI). SEM was used to evaluate the influences of variables proximal and distal to child …

The Effects Of Sour & Spicy Food On Visual & Auditory Reflexes, Aditi Kumar, Alondra-Sophia Martinez, Magdalena E. Saad, Emma J. Welsch

Posters - 2026

• The reflex reaction time measures how quickly the nervous system can respond to a stimulus. • In the experiment, both visual and auditory reflexes were measured to evaluate differences in reaction time after the consumption of sour and spicy foods. • Spices and herbs produce different signals that interact with the nervous system. (McMullen 2024) • Comparing the response times from before and after consumption, this experiment allowed us to determine if different tastes affect reflex reaction times.

Does The Placenta Predict Depression During Pregnancy? Investigating Hormonal Links In High-Risk Pregnancies, Sonia Cerrillo, Hanne Hoffmann Phd

Posters - 2026

• Perinatal depression is a common disorder that affects maternal and infant well-being.

• Serotonin is an important mood-regulating neurotransmitter, and reduced serotonin signaling has been linked to depressive symptoms.

• Tryptophan (TRP) is the precursor for serotonin, where most TRP is metabolized through the kynurenine pathway.

• TPH supports serotonin synthesis, while IDO and TDO drive kynurenine production.

• During pregnancy, inflammation and stress may shift TRP away from serotonin, creating a placental “tryptophan steal.”

• We examined whether placental DNA methylation of these genes differs in high-risk pregnancies.

• We hypothesized that placental DNA methylation of genes in …

Hyperglycemia And Mycoplasma Pneumoniae Cards Toxin Impacts On Lung Epithelial And Fibroblast Injury And Recovery, Alejandra Y. Delgado, Naila Villagomez, Shuri Magdalene

Posters - 2026

Mycoplasma pneumoniae CARDS toxin induces cytotoxicity and inflammation in lung epithelial cells²·¹⁰·¹¹, while hyperglycemia independently elevates ROS and disrupts fibroblast repair¹·⁵·⁸, contributing to the heightened respiratory infection severity seen in diabetic patients¹. However, the interaction between hyperglycemic conditions and CARDS toxin-induced lung injury remains unexplored.

This study investigates how increasing high-glucose (HG) pre-conditioning modifies CARDS toxin-induced injury and recovery in A549⁶ and IMR-90⁷ cells compared to normal glucose (NG ≈ 5mM) controls. We hypothesized that increasing glucose pre-conditioning concentrations would produce a dose-dependent increase in CARDS toxin-induced oxidative stress¹² and inflammatory cytokine production¹⁵ in IMR-90 and A549 compared with normal …

Trends In Meningioma-Related Mortality Among U.S. Adults: A Cdc Wonder Analysis From 2000 To 2023, Tirath Patel, Rai Muhammad Umar Khan, Fatima Hussain, Meer Murtaza, Muhammad Shayan Tariq, Abuzar Khan, Sara Aleem, Maryam Athar, Sharoz Shahid, Nikhilesh Anand

School of Medicine Publications

Background: Meningiomas are the most common primary intracranial tumors in the United States, comprising nearly 41% of central nervous system tumors. While the majority are benign, atypical (World Health Organization Grade II) and malignant (Grade III) subtypes are clinically significant due to their aggressive biology, higher recurrence, and increased mortality risk. Despite their burden, national mortality trends and demographic disparities in meningioma-related deaths remain underexplored.

Methods: We conducted a population-based analysis of meningioma-related mortality among U.S. adults aged ≥65 years from 1999 to 2023 using the centers for disease control and prevention (CDC) wide-ranging online data for epidemiologic research (WONDER) …

Copy number variants (CNVs) are key drivers of human diversity and disease risk1. Here we evaluate the role of CNVs across a broad range of human phenotypes and diseases by analysing CNVs from 470,727 UK Biobank whole-genome sequences and conducting a variant- and gene-level phenome-wide association study (PheWAS) with 2,941 plasma protein abundance measurements, 13,336 binary clinical phenotypes and 1,911 quantitative traits. Proteomic analyses validated functional associations of CNVs with nearby genes (cis-protein quantitative trait loci; cis-pQTLs)—with deletions and duplications typically associated with reduced and increased protein levels, respectively—and uncovered previously unknown protein–protein interactions …

Knowledgable Births: Advancing Informed Consent In Maternal Healthcare, Ella A. Forrester

Senior Theses

Background:

Informed consent is both a legal requirement and an ethical cornerstone of healthcare, ensuring that patients understand and voluntarily agree to medical treatments. However, evidence suggests that the informed consent process is often inadequately implemented in maternal healthcare settings, particularly during childbirth. While giving birth, women retain full decision-making capacity but are not consistently provided with sufficient information or support to exercise this right. Contributing factors include ineffective patient–provider communication, limited health literacy, and insufficient access to culturally responsive educational resources.

Methods:

This study aimed to address gaps in accessible prenatal education by developing an online resource platform, Know …

Faculty, Staff and Student Publications

Objective: Complement component 4 (C4), encoded by C4A and C4B within the major histocompatibility complex (MHC) on chromosome 6, regulates the immune response and clears immune complexes. The variable copy number (CN) of C4 genes and retroviral human endogenous retrovirus K (HERV-K) element influence its function. Given the relationship of C4 CN with systemic sclerosis (SSc) risk, we assessed associations with SSc clinical and serologic subtypes.

Methods: We compared imputed C4 CNs across SSc subgroups (4,049 anticentromere positive [ACA+]; 2,200 anti-topoisomerase I [ATA+]; 577 anti-RNA polymerase [ARA+]; 1,078 triple-negative [TN] patients; 6,295 limited cutaneous SSc [lcSSc]; and 2,946 diffuse cutaneous …

Purpose: To investigate contrast-enhanced T1-weighted MRI and diffusion-weighted magnetic resonance imaging (DWI) for early prediction of tumor response to combined irreversible electroporation (IRE) and anti-PD-1 immunotherapy.

Methods: Murine pancreatic ductal adenocarcinoma (PDAC) cells KRAS* were inoculated into the pancreas of C57BL/6 mice. IRE was performed when tumors became palpable. After IRE, mice received six intraperitoneal injections of anti-PD-1 over 2 weeks. T2-weighted MRI, T1-weighted MRI with macromolecular contrast agent poly(L-glutamic acid)-conjugated gadolinium (PG-Gd), and DWI were performed before and after IRE. Survival was analyzed using Kaplan-Meier curves. Mice surviving at least 100 days without recurrence after IRE were considered complete …

Neutrophil-Microglia Interaction Drives Motor Dysfunction In A Neuromyelitis Optica Model Induced By Subarachnoid Aqp4-Igg, Fangfang Qi, Vanda A Lennon, Shunyi Zhao, Yong Guo, Husheng Ding, Caiyun Liu, Whitney M Bartley, Tingjun Chen, Claudia F Lucchinetti, Long-Jun Wu

Faculty, Staff and Student Publications

Neutrophils and neutrophil extracellular traps (NETs) contribute to early neuromyelitis optica (NMO) histopathology initiated by IgG targeting astrocytic aquaporin-4 (AQP4) water channels. Yet, the mechanisms underlying neutrophil recruitment and their pathogenic roles in disease progression remain unclear. To investigate molecular-cellular events preceding classical complement cascade activation in a mouse NMO model, we continuously infused, via spinal subarachnoid route, a non-complement-activating mouse monoclonal AQP4-IgG. Parenchymal infiltration of netting neutrophils containing C5a ensued with microglial activation and motor impairment but no blood-brain barrier leakage. Motor impairment and neuronal dysfunction both reversed when AQP4-IgG infusion stopped. Two-photon microscopy and electron microscopy-based reconstructions revealed …

Gompertz Growth With A Shared Carrying Capacity Optimally Simulates Primary And Metastatic Tumor Growth Dynamics, Pirmin Schlicke, Preethi Korangath, Xiaoxi Pan, Caner Ercan, Kathleen Gabrielson, Lyndsey Werhane, Yinyin Yuan, Sébastien Benzekry, Robert Ivkov, Heiko Enderling

Faculty, Staff and Student Publications

Background: Cancer is a systemic disease with most deaths attributed to metastatic burden. Primary and metastatic tumors, albeit at different anatomic locations, are interconnected through multiple biological processes. Pre-clinical and clinical observations of growth acceleration of metastases after surgery, or abscopal effects outside the radiation field are widely reported, yet reliably triggering favorable and avoiding unfavorable systemic responses remains an unmet clinical need. Understanding local and systemic tumor interaction dynamics will help guide future treatments.

Methods: We analyze the data of multiple in vivo tumor models. We formalize the systemic interplay of tumors as mathematical differential equation and calibrate parameters …

Faculty, Staff and Student Publications

Huntington's disease (HD) is a neurodegenerative disorder caused by an abnormal CAG expansion in the Huntingtin (HTT) gene. Given its simple genetic cause but complex pathogenic mechanisms, interest in targeting HTT for HD treatment is growing, necessitating a clear understanding of HTT regulation. HTT protein primarily exists in a core complex with HAP40, forming a highly ordered structure with two large globular domains connected by a bridge. We previously demonstrated that HAP40 is conserved in

Dyadic Associations Between Stress And Sleep Quality And Moderating Effects Of Emotional Intimacy And In Survivors Of Young Adult Cancer And Their Spouses: An Observational Study, Haejeong An, Seokhun Kim, Michael Roth, Kathrin Milbury, Dalnim Cho

Faculty, Staff and Student Publications

Background: Survivors of young adult (YA) cancer often experience substantial stress during the transition to survivorship, which may impair sleep. Although the stress-sleep link is well established, its role within survivor-spouse dyads remains unclear. Emotional intimacy may influence how couples regulate stress and affect sleep. This study examined dyadic associations between stress and sleep among survivors of YA cancer and their spouses and significant others (hereafter spouses) and tested emotional intimacy as a moderator.

Methods: A total of 103 survivor of YA cancer-spouse dyads completed self-reported measures of stress, emotional intimacy, and sleep quality. An actor-partner interdependence moderation model was …

Probability Of Fentanyl Adulteration In Cocaine Selectively Decreases Cocaine Demand, Cecilia Nunez, Jin H Yoon, James Mackillop, Margaret C Wardle

Faculty, Staff and Student Publications

Fentanyl-related, cocaine-overdose deaths have drastically increased, yet research on how people who use cocaine perceive fentanyl adulteration is limited. This study developed the novel Adulterated Cocaine Purchasing Task (ACocPT), a modification of the original Cocaine Purchasing Task, to quantify how people respond to fentanyl adulteration in cocaine. In the ACocPT, participants indicated how much cocaine they would purchase when cocaine had no (0%) vs. some (10%) probability of fentanyl adulteration. Study aims were: 1) determine how possible fentanyl adulteration affects cocaine demand, and 2) determine which individual characteristics predict continued demand for cocaine despite fentanyl adulteration. This Amazon Mechanical Turk …
