Exceptional Response Of Radiotherapy-Naïve Cranial Meningiomas To Dual Immune Checkpoint Blockade In Bap1 Tumor Predisposition Syndrome, Gary Gallia, Christine Hann, Calixto-Hope Lucas, Licia Pacheco Luna, David Kamson, Takami Sato

Department of Medical Oncology Faculty Papers

Meningiomas are the most common primary central nervous system tumors, and while most are benign, atypical and anaplastic variants frequently recur and have limited effective treatment options. Recent trials of PD-1 blockade in unselected meningioma cohorts have demonstrated modest activity, with low objective response rates. These findings highlight the need to identify molecular biomarkers that may predict immunotherapy sensitivity in this disease. BRCA1-associated protein 1 (BAP1) is a tumor suppressor critical for chromatin regulation and DNA repair, and germline pathogenic variants cause BAP1 tumor predisposition syndrome (BAP1-TPDS), a hereditary cancer syndrome characterized by uveal melanoma, mesothelioma, renal cell carcinoma, meningioma, …

Center for Translational Medicine Faculty Papers

MCU, originally known as CCDC109A, is widely recognized as the gene responsible for encoding a pore-forming subunit of a Ca2+-selective channel, mitochondrial Ca2+ uniporter complex (mtCUC). While MCU expression is typically highly mitochondrial-specific, we report here a protein variant derived from the MCU gene, termed MCU-S, which lacks the mitochondria-targeting sequence (MTS) and forms a Ca2+-permeable channel outside of mitochondria. The mRNA of MCU-S was ubiquitously expressed in all cell types/tissues tested, with particularly high expression in human platelets. MCU-S protein formed Ca2+ channels at the plasma membrane, which exhibited similar channel properties to those observed in mtCUC. MCU-S channels …

Repurposing Semaglutide As An Adjunctive Treatment For Cocaine Use Disorder: Protocol For A Randomised Controlled Trial, Luba Yammine, Francesco Versace, Charles E Green, Heather E Webber, Jin Ho Yoon, Absalon D Gutierrez, Samuel J Leonard, Michael F Weaver, Joy Schmitz

Faculty, Staff and Student Publications

Introduction: Cocaine use disorder (CUD) is a significant public health concern in the USA, with considerable prevalence and mortality and no Food and Drug Administration (FDA)-approved pharmacotherapies. Recent advances in addiction science emphasise the need for novel, mechanism-based treatments. Glucagon-like peptide-1 receptor agonists, such as semaglutide, have shown promise in modulating reward-related behaviours and may offer therapeutic benefits for CUD. We present a study protocol evaluating semaglutide, as an adjunct to cognitive behavioural therapy (CBT), as a novel approach for treating CUD.

Methods and analysis: This is a randomised, double-blind, placebo-controlled trial enrolling 75 treatment-seeking adults with CUD. Participants will …

Brain-Wide Structural Markers Of Familial And Clinical Risk For Bipolar Disorder In Youth, Danella M Hafeman, Jamie Feldman, John Merranko, Mary L Phillips, Boris Birmaher, Si Gao, Yizhou Ma, Peter Kochunov

Faculty, Staff and Student Publications

Background: Bipolar Disorder (BD) is a severe mental illness, often emerging during adolescence, that is associated with significant psychosocial impairment. BD risk is elevated in offspring of affected parents, particularly those with antecedent symptoms (e.g., mood lability, subthreshold manic symptoms). However, robust, replicable brain-based markers of risk in this population are lacking. We assessed the degree to which the Regional Vulnerability Index for BD (RVI-BD), quantified as an individual's brain-wide similarity to BD patterns derived from meta-analytic studies, is elevated in youth at familial risk and correlates with symptom predictors of BD.

Methods: We recruited n=82 adolescents (10-15 years old), …
