There are limited therapeutic options for patients with advanced sarcomas, which leads to dismal outcomes for children and adults. Although chimeric antigen receptor (CAR) T cells hold promise for treating advanced sarcomas, this approach is constrained by a paucity of effective targets. Our previous clinical study identified endoglin (ENG/CD105), a TGFβ coreceptor, as a target of the endogenous immune response in a patient with sarcoma who exhibited an exceptional response to HER2-targeted CAR T-cell therapy. ENG is expressed on various sarcomas, cancer-associated fibroblasts, and neoangiogenic vessels and therefore offers comprehensive tumor targeting. Furthermore, ENG knockout in sarcoma cells reduces their …

The consumption of sugar-sweetened beverages (SSBs), which contain high levels of fructose and glucose, has been causally and mechanistically linked to an increased risk of colorectal cancer (CRC). However, the effects of SSB consumption on advanced stages of disease progression, including metastasis, remain poorly understood. Here we show that exposure of CRC cells to a glucose and fructose formulation-reflecting the composition of both high-fructose corn syrup and sucrose found in SSBs-enhances cellular motility and metastatic potential compared to glucose alone. Given that CRC cells grow poorly in fructose alone, and cells in vivo are not physiologically exposed to fructose without …

Transdiagnostic Correlates Of Family Accommodation In Anxious Youth, Whitney S Shepherd, Erika S Trent, Orri Smarason, Hannah N Sansone, Daphne M Ayton, Amanda Palo, Abigail E Candelari, Wayne K Goodman, Andrew G Guzick, Eric A Storch

Faculty, Staff and Students Publications

Anxiety disorders are common in children and cause significant impairment. Family accommodation, which refers to behavioral changes that family members make to temporarily alleviate a child’s anxiety, has been linked to child anxiety symptom severity. Although emotional vulnerabilities for anxiety such as emotion dysregulation, anxiety sensitivity, and distress intolerance have been associated with family accommodation, research concerning the relationship between these constructs among anxious youth is limited. We hypothesized that these variables would be uniquely and positively associated with family accommodation and would moderate the relationship between anxiety symptom severity and family accommodation. Treatment-seeking child–parent dyads (N = 90; …

Using Latent Patient-Centered Fear Extinction Profiles To Guide Treatment In Pediatric Ocd, Katherine M Ingram, Eric A Storch, Daniel A Geller, Brent J Small, Sabine Wilhelm, Joseph F Mcguire

Faculty, Staff and Students Publications

Background: While exposure with response prevention (ERP) is the frontline treatment for pediatric obsessive-compulsive disorder (OCD), not all patients benefit. Impairments in extinction learning are implicated in pediatric OCD's etiology and treatment, with impaired pre-treatment extinction learning associated with worse ERP outcomes. However, available methods for assessing patients' difficulties with fear extinction are costly and underdeveloped. In response, we used person-centered profiles to characterize latent fear extinction patterns among youth with OCD, and investigated the degree to which scores on common rating scales correspond to profile membership.

Methods: Youth with OCD (n=98) completed a diagnostic clinical battery followed by a …

Integration of measurement-based care (MBC) into clinical practice has shown promise in improving treatment outcomes for depression. Yet, without a gold standard measure of MBC, assessing fidelity to the MBC model across various clinical settings is difficult. A central goal of the Texas Youth Depression and Suicide Research Network (TX-YDSRN) was to characterize MBC across the state of Texas through the development of a standardized tool to assess the use of MBC strategies when assessing depression, anxiety, side effects, and treatment adherence. A chart review of clinical visits indicated standardized depression measures (71.2%) and anxiety measures (64%) were being utilized …

Prostaglandin E2 As A Mechanistic Biomarker Of Chronic Pancreatitis, Jami L Saloman, Bahiyyah Jefferson, Samuel Han, William E Fisher, Evan L Fogel, Phil A Hart, Liang Li, Walter G Park, Santhi Swaroop Vege, Dhiraj Yadav, Mark D Topazian, Darwin L Conwell

Faculty, Staff and Students Publications

Introduction: Chronic pancreatitis (CP) is a disease associated with chronic inflammation, fibrosis, and pain. There is a lack of tools available that facilitate early diagnosis, when intervention could prevent irreversible damage. Pilot data suggested prostaglandin E2 (PGE2) as a candidate biomarker for early CP. PGE2 activates signaling pathways that promote inflammation, pain, and fibrosis.

Methods: We assessed PGE2, metabolites, and downstream targets in pancreatic fluid collected endoscopically 0-10 (n = 110) and 10-20 (n = 111) minutes after intravenous secretin administration. PGE2 and metabolites were measured in plasma (n = 75) and urine (n = 71) from the same subjects. …

Faculty, Staff and Student Publications

Adult-type granulosa cell tumors (AGCT) are rare ovarian tumors with few effective treatments for recurrent disease. To elucidate spatial features and cellular interactions within the AGCT tumor microenvironment, we applied imaging mass cytometry using a 34-marker panel on 130 regions from 24 AGCT samples, profiling more than 900,000 single cells. Analysis confirmed the immune “cold” phenotype of AGCTs and showed higher macrophage abundance in recurrent compared with primary tumors. We observed substantial heterogeneity in tissue architecture across samples, including variable presence of FOXL2+ cells embedded in collagen-rich regions (FOXL2+COL1A1+ cells). Based on tumor microenvironment composition, we defined two AGCT subtypes: …

Transfer Learning Via Distributed Brain Recordings Enables Reliable Speech Decoding, Aditya Singh, Tessy Thomas, Jinlong Li, Greg Hickok, Xaq Pitkow, Nitin Tandon

Faculty, Staff and Student Publications

Speech brain-computer interfaces (BCIs) combine neural recordings with large language models to achieve real-time intelligible speech. However, these decoders rely on dense, intact cortical coverage and are challenging to scale across individuals with heterogeneous brain organization. To derive scalable transfer learning strategies for neural speech decoding, we used minimally invasive stereo-electroencephalography recordings in a large cohort performing a demanding speech motor task. A sequence-to-sequence model enabled decoding of variable-length phonemic sequences prior to and during articulation. This enabled development of a cross-subject transfer learning framework to isolate shared latent manifolds while enabling individual model initialization. The group-derived decoder significantly outperformed …

CEACAM5, a cell surface protein, is overexpressed in colorectal cancer (CRC). Precemtabart tocentecan (Precem-TcT, previously M9140) is an anti-CEACAM5 antibody–drug conjugate with the topoisomerase 1 inhibitor exatecan as payload. Precem-TcT demonstrated strong antitumor activity and potent bystander activity in preclinical models. Its toxicity profile in cynomolgus monkeys was consistent with that of exatecan. In the dose-escalation stage of the phase 1 trial of Precem-TcT (PROCEADE-CRC-01), 40 heavily pretreated patients with irinotecan-refractory metastatic CRC received Precem-TcT every 3 weeks across seven dose levels (DLs, 0.6–3.2 mg kg−1). Primary endpoints were dose-limiting toxicities (DLTs), adverse events and preliminary clinical activity to establish …

Prostate cancer (PCa) bone metastasis (BM) poses a significant clinical challenge due to the heterogeneity of treatment responses and patient outcomes. In this study, we examined the role of Protein Kinase A (PKA) signaling in modulating the expression of osteopontin (SPP1/OPN), a protein associated with poor prognosis, within a subset of PCa BM patients. By integrating multi-omics results we identified a novel mechanism in which bone-derived type-I collagen (Col1a1) and fibronectin (Fn1) stimulate SPP1 expression in PCa cells through the activation of PKA signaling. This bone-induced regulation of SPP1 was confirmed both in vitro, using PCa-bone co-culture systems (PC3 or …

Perineural invasion (PNI) is a well-established factor of poor prognosis in multiple cancer types1, yet its mechanism remains unclear. Here we provide clinical and mechanistic insights into the role of PNI and cancer-induced nerve injury (CINI) in resistance to anti-PD-1 therapy. Our study demonstrates that PNI and CINI of tumour-associated nerves are associated with poor response to anti-PD-1 therapy among patients with cutaneous squamous cell carcinoma, melanoma and gastric cancer. Electron microscopy and electrical conduction analyses reveal that cancer cells degrade the nerve fibre myelin sheets. The injured neurons respond by autonomously initiating IL-6- and type I interferon-mediated …

Kimmel Cancer Center Faculty Papers

Human T-cell leukemia virus type 1 (HTLV-1), the first oncogenic human retrovirus, causes adult T-cell leukemia/lymphoma (ATLL), an aggressive neoplasm of mature CD4+ T-cells that is incurable in most patients and is associated with a median survival of less than 1 year. HTLV-1 also causes inflammatory disorders, including HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and uveitis. The estimated lifetime risks of ATLL and HAM/TSP in HTLV-1 carriers are 3-5% and 0.25-1.8%, respectively. Although there is uncertainty about other health effects of HTLV-1, a recent meta-analysis showed an association between HTLV-1 and cardiovascular, cerebrovascular, and metabolic diseases and a 57% increased risk …
