Surface Marker Identification To Capture Live Circulating Tumor Cells In Metastatic Triple-Negative Breast Cancer, Bree M Lege, Khushali J Patel, Brendan Panici, Ping Gong, Michael T Lewis, Matthew J Ellis, Chonghui Cheng

Faculty, Staff and Students Publications

Metastatic triple-negative breast cancer (TNBC) is highly aggressive and lacks targeted therapies. Circulating tumor cells (CTC) are invaluable for monitoring metastatic tumor progression and treatment response but are difficult to capture because of their rarity and heterogeneity. Surface-based staining for live CTCs is essential to preserve RNA quality in single cells, but current markers tend to perform poorly on more mesenchymal tumor cells such as TNBCs. To enhance live TNBC CTC detection, we developed a workflow for live CTC capture and single-cell RNA sequencing (scRNA-seq). Using a mouse model of metastatic TNBC, we identified four new CTC surface markers, AHNAK2, …

Priced Out Of Treatment: The Exorbitant Cost Of Antiparasitic Drugs In The United States, Cora Alperin, Nhi Nguyen, Megan Duffey, Eva H Clark

Faculty, Staff and Students Publications

Parasitic infections are often perceived as diseases of low-resource countries, yet they impose a significant and overlooked burden in the United States—especially among immigrants, low-income individuals, and other marginalized populations. This perspectives article examines the case of Mr. X, a landscaper in Houston diagnosed with neurocysticercosis, who faced unaffordable drug costs despite the availability of effective, off-patent treatments. Through his story, we explore the broader issue of pricing for commonly and not-so-commonly prescribed antiparasitic medications, highlighting the role of systemic market failures, regulatory hurdles, and restrictive assistance programs in limiting access to care. The consequences of incomplete treatment include long-term …

Medical Device Dangers: Choosing Ignorance In The Courts And At The Fda, George Horvath

Faculty Scholarship

Medical devices save lives and improve well-being but have caused as many as 83,000 deaths and 1.7 million injuries in a recent decade. Decisions of critical importance—patients’ decisions whether to have a device implanted, doctors’ decisions about which device to use, insurers’ decisions whether to reimburse for those devices—depend on information about risk that is provided by manufacturers. But producing this information is costly. Injured patients, through private lawsuits under state products liability theories, can incentivize device manufacturers to incur these costs and to produce and disclose information about device risk. Unfortunately, courts are making it increasingly unlikely that this …

The Lived Experience Of Pediatric Pain Management: Insights From Families And Providers, Samrithaa Balakrishnan, Annesha Dey, Aarti Bavare, Paul Checchia, Katherine Shwetz, Natasha Afonso

Faculty, Staff and Students Publications

Pain represents a subjective experience that manifests with emotional and physical discomfort. In pediatric care, pain management is especially complex due to communicative limitations, which creates a unique point of entry for parents to contribute to their child's treatment process. In this study, we explored whether families' perceptions of their child's pain and preferences for treatment were aligned with healthcare providers' pain management decisions. Using narrative-informed techniques in interviews with families and healthcare providers in pediatric care settings, we analyzed areas of concordance and discordance in pain assessment and treatment priorities. Our findings show that trust is built over time …

Students scanned pickles, hard-boiled eggs, and olives with pits; these items were selected for their low cost, sonographic characteristics, and recognizability. Later in the semester, …

A Conceptual Framework For Cognitive Engagement And Human Agency In Ai-Mediated Learning, Sam Rhodes, Zuhal Yilmaz, Terrie Galanti, Younggon Bae, Victoria Delaney, Zareen Gul Aga, Stephen Hutt

School of Mathematical & Statistical Sciences Faculty Publications

The purpose of this chapter is to propose a conceptual framework that unpacks AI use in instructional practice across three interrelated dimensions: human agency, cognitive demand, and AI orchestration. We ground this work in historical perspectives on technology's mediating role in education. We then propose the conceptual framework and three characterizations of the use of AI in school instruction: cognitive load reducer, cognitive capacity builder, and cognitive companion. We then illustrate a worked example of each, including a curricular example and sample student prompts, and conclude with questions that educators might ask themselves as they consider if and how to …

Genome-Wide Association Study Identifies And Validates Genetic Variation In The Rig-I/Mavs Signaling Pathway Associated With Hiv-Related Kaposi Sarcoma In Children And Adults, Casey L Mcatee, Erin Peckham-Gregory, Pagna Sok, Melissa Richard, Luis Olivares, Deborah Marquez-Do, Grace Kisitu, Jeffrey Martin, Nader Kim El-Mallawany, Carl E Allen, Joseph Lubega, Michael E Scheurer

Faculty, Staff and Students Publications

Introduction: Immune deficiency and infection with human herpesvirus-8 (HHV-8) are established component causes of Kaposi sarcoma (KS), but they are insufficient to cause disease in most people at risk. Therefore, we hypothesized that genetic variation may contribute to KS risk in children and adults, as well as contribute to its unique epidemiology in sub-Saharan Africa.

Methods: To test this hypothesis, we conducted a two-phase genome-wide association study (GWAS): a discovery study in perinatally HIV-infected children (45 KS cases, 91 controls), followed by validation of significant results in a sample of adults living with HIV (215 cases, 262 controls). After standard …

Many patients with advanced solid tumors ultimately develop resistance to conventional therapies, with especially limited options for those experiencing rapid progression or poor performance status, highlighting the need for personalized immunotherapies capable of inducing durable responses. In this retrospective case series, we describe the clinical course and outcomes of five adults (4 male, 1 female; median age 51 years [range, 39-62]) with metastatic solid tumors who achieved complete and durable remission following doubly loaded autologous dendritic cell therapy after failure of standard treatments, such as immune checkpoint inhibition, radiation, surgery, or endocrine therapy. Five patients, including prostate adenocarcinoma (n=1), malignant …

Metabolites Produced By Agat+ Cells Support Regeneration In The Planarian Schmidtea Mediterranea, Aubrey M Kent, Carlos Guerrero-Hernández, Carolyn Brewster, Sean Mckinney, Jason A Morrison, Mary C Mckinney, Eric J Ross, Frederick G Mann, Blair W Benham-Pyle, Alejandro Sánchez Alvarado

Faculty, Staff and Students Publications

Planarians exhibit extraordinary regenerative abilities driven by pluripotent neoblasts, yet the roles of post-mitotic progenitor and differentiated cells in this process remain incompletely understood. Here, we investigate the function of agat+ cells, epidermal progenitors expressing members of the arginine:glycine amidinotransferase (agat) gene family, in the regeneration of Schmidtea mediterranea. Comprehensive analysis of all five planarian agat paralogs revealed that agat-1, -2, -3, and -4 are co-expressed in subepidermal populations enriched at wound sites, while agat-5 is minimally expressed. RNAi-mediated knockdown of agat-1 and agat-2 resulted in severe defects: agat-1 primarily disrupted tissue homeostasis, …

Faculty, Staff and Students Publications

To mitigate limitations in self-reported mood assessments, we introduce a novel affective bias task (ABT). The task quantifies instantaneous emotional state by leveraging the phenomenon of affective bias, in which people interpret external emotional stimuli in a manner consistent with their current emotional state. This study establishes task stability in measuring and tracking depressive symptoms in clinical and non-clinical populations. Initial assessment in a large non-clinical sample established normative ratings. Depressive symptoms were tracked relative to task performance in a non-clinical sample, as well as in a clinical cohort undergoing surgical evaluation for severe epilepsy. In both cohorts, a stronger …

Human papillomavirus (HPV) is a major driver of global cancer incidence, responsible for nearly all cervical cancers and a significant proportion of oropharyngeal, anal, and other anogenital cancers. Despite the availability of effective vaccines, HPV-associated cancers persist due to persistent infection, immune evasion, and the virus's ability to integrate into the host genome, contributing to molecular heterogeneity and therapeutic resistance. Here, we summarize molecular heterogeneity and the emerging combined therapeutic strategies. High-risk HPV types, notably HPV16 and HPV18, initiate carcinogenesis through persistent infection of epithelial basal cells and through the actions of the E6 and E7 oncoproteins, which disrupt the …

Faculty, Staff and Students Publications

Introduction: Hispanic/Latino (H/L) adults are more likely than non-Hispanic White individuals to have Alzheimer's disease (AD), yet fewer than one in five H/L adults has apolipoprotein E (APOE) Ɛ4, underscoring gaps in understanding genetic risk across H/L heritage groups. H/L adults remain underrepresented in AD research that uses genetic data for participant stratification. To inform culturally appropriate educational materials for 16 million U.S. Spanish speakers, we identified culturally salient words Spanish-preferring H/L adults use to describe AD and genetic testing beyond APOE.

Methods: Community-residing, Spanish-preferring Mexican/Mexican American adults (n = 14) completed freelisting interviews, a method eliciting …

Open Secrets, Robin C. Feldman, Vaughn Goehrig

Faculty Scholarship

Patents and trade secrets were never intended to meet, but in the world of biologic drugs, they've become as thick as thieves. Patent law's disclosure requirement has demanded far too little of biologics manufacturers-allowing them to keep vital manufacturing details under trade secret lock and key. This intellectual property patchwork has been devastating for drug affordability: Because the most critical manufacturing information remains hidden, makers of follow-on biologics (called biosimilars) are often stuck reinventing the wheel, even after the original patents have expired.

This Article makes two principal contributions to illuminating this problem. First, it presents, for the first time …
