Faculty, Staff and Student Publications

Sitravatinib (MGCD516) is an oral inhibitor of several closely related oncogenic tyrosine kinase receptors that include VEGFR-2 (vascular endothelial growth factor receptor-2), AXL, and MET (mesenchymal-epithelial transition). The safety and antitumor activity of sitravatinib are reported in patients from two histologic cohorts (anti-angiogenesis-refractory clear cell renal cell carcinoma [RCC] and castrate-resistant prostate cancer [CRPC] with bone metastases) who participated in a Phase 1/1b study. The patients were enrolled using a 3-stage design that was based on observed objective responses. Objective response rate (ORR) was the primary endpoint. Duration of response, progression-free survival (PFS), overall survival (OS), and safety were also …

Extent Of Resection Thresholds In Molecular Subgroups Of Newly Diagnosed Isocitrate Dehydrogenase-Wildtype Glioblastoma, Antonio Dono, Ping Zhu, Takeshi Takayasu, Octavio Arevalo, Roy Riascos, Nitin Tandon, Leomar Y Ballester, Yoshua Esquenazi

Faculty, Staff and Student Publications

Background and objectives: Maximizing the extent of resection (EOR) improves outcomes in glioblastoma (GBM). However, previous GBM studies have not addressed the EOR impact in molecular subgroups beyond IDH1/IDH2 status. In the current article, we evaluate whether EOR confers a benefit in all GBM subtypes or only in particular molecular subgroups.

Methods: A retrospective cohort of newly diagnosed GBM isocitrate dehydrogenase (IDH)-wildtype undergoing resection were prospectively included in a database (n = 138). EOR and residual tumor volume (RTV) were quantified with semiautomated software. Formalin-fixed paraffin-embedded tumor tissues were analyzed by targeted next-generation sequencing. The association between recurrent genomic alterations …

Unlocking Ferroptosis In Prostate Cancer – The Road To Novel Therapies And Imaging Markers, Pham Hong Anh Cao, Abishai Dominic, Fabiola Ester Lujan, Sanjanaa Senthilkumar, Pratip K Bhattacharya, Daniel E Frigo, Elavarasan Subramani

Faculty, Staff and Student Publications

Ferroptosis is a distinct form of regulated cell death that is predominantly driven by the build-up of intracellular iron and lipid peroxides. Ferroptosis suppression is widely accepted to contribute to the pathogenesis of several tumours including prostate cancer. Results from some studies reported that prostate cancer cells can be highly susceptible to ferroptosis inducers, providing potential for an interesting new avenue of therapeutic intervention for advanced prostate cancer. In this Perspective, we describe novel molecular underpinnings and metabolic drivers of ferroptosis, analyse the functions and mechanisms of ferroptosis in tumours, and highlight prostate cancer-specific susceptibilities to ferroptosis by connecting ferroptosis …

Inhibition Of Hepatic Oxalate Overproduction Ameliorates Metabolic Dysfunction-Associated Steatohepatitis, Sandeep Das, Alexandra C Finney, Sumit Kumar Anand, Sumati Rohilla, Yuhao Liu, Nilesh Pandey, Alia Ghrayeb, Dhananjay Kumar, Kelley Nunez, Zhipeng Liu, Fabio Arias, Ying Zhao, Brenna H Pearson-Gallion, M Peyton Mckinney, Koral S E Richard, Jose A Gomez-Vidal, Chowdhury S Abdullah, Elizabeth D Cockerham, Joseph Eniafe, Andrew D Yurochko, Tarek Magdy, Christopher B Pattillo, Christopher G Kevil, Babak Razani, Md Shenuarin Bhuiyan, Erin H Seeley, Gretchen E Galliano, Bo Wei, Lin Tan, Iqbal Mahmud, Ida Surakka, Minerva T Garcia-Barrio, Philip L Lorenzi, Eyal Gottlieb, Eduardo Salido, Jifeng Zhang, A Wayne Orr, Wanqing Liu, Monica Diaz-Gavilan, Y Eugene Chen, Nirav Dhanesha, Paul T Thevenot, Ari J Cohen, Arif Yurdagul, Oren Rom

The incidence of metabolic dysfunction-associated steatohepatitis (MASH) is on the rise, and with limited pharmacological therapy available, identification of new metabolic targets is urgently needed. Oxalate is a terminal metabolite produced from glyoxylate by hepatic lactate dehydrogenase (LDHA). The liver-specific alanine-glyoxylate aminotransferase (AGXT) detoxifies glyoxylate, preventing oxalate accumulation. Here we show that AGXT is suppressed and LDHA is activated in livers from patients and mice with MASH, leading to oxalate overproduction. In turn, oxalate promotes steatosis in hepatocytes by inhibiting peroxisome proliferator-activated receptor-α (PPARα) transcription and fatty acid β-oxidation and induces monocyte chemotaxis via C-C motif chemokine ligand 2. In …

Temporal ordering of cellular events offers fundamental insights into biological phenomena. Although this is traditionally achieved through continuous direct observations1,2, an alternative solution leverages irreversible genetic changes, such as naturally occurring mutations, to create indelible marks that enables retrospective temporal ordering3–5. Using a multipurpose, single-cell CRISPR platform, we developed a molecular clock approach to record the timing of cellular events and clonality in vivo, with incorporation of cell state and lineage information. Using this approach, we uncovered precise timing of tissue-specific cell expansion during mouse embryonic development, unconventional developmental relationships between cell …

Faculty, Staff and Student Publications

Purpose: The Provisional Extension to Induce Complete Attachment Technique (PETTICOAT) uses a bare-metal stent to scaffold the true lumen in patients with acute or subacute aortic dissections. While it is designed to facilitate remodeling, some patients with chronic post-dissection thoracoabdominal aortic aneurysms (TAAAs) require repair. This study describes the technical pitfalls of fenestrated-branched endovascular aortic repair (FB-EVAR) in patients who underwent prior PETTICOAT repair.

Technique: We report 3 patients with extent II TAAAs who had prior bare-metal dissection stents treated by FB-EVAR. Two patients required maneuvers to reroute the aortic guidewire, which was initially placed in-between stent struts. This was …

Percutaneous Sacral Screw Fixation Alone Sufficient For Mildly Displaced U-Type Sacral Fractures With Preserved Osseous Fixation Pathways, Augustine M Saiz, Patrick J Kellam, Adeet Amin, Zachary Arambula, Abhi Rashiwala, Joshua L Gary, Stephen J Warner, Milton Routt, Jonathan G Eastman

Faculty, Staff and Student Publications

Purpose: To describe U-type sacral fracture characteristics amenable to percutaneous sacral screw fixation.

Methods: U-type sacral fractures were identified from a trauma registry at a level 1 trauma center from 2014 to 2020. Patient demographics, injury mechanism, fracture characteristics, and fixation construct were retrospectively retrieved. Associations between fracture pattern and surgical fixation were identified.

Results: 82 U-type sacral fractures were reviewed. Six treated with lumbopelvic fixation (LPF) and 76 were treated with percutaneous sacral screws (PSS) alone. Patients receiving LBF had greater sacral fracture displacement in coronal, sagittal, and axial planes compared to patients receiving PSS alone (P < 0.05), negating osseous fixation pathways. All patients went onto sacral union and there were no implant failures or unplanned reoperations for either group.

Faculty, Staff and Student Publications

Introduction: The United States has the highest teen pregnancy rate and sexually transmitted infection rates among developed countries. One common approach that has been implemented to reduce these rates is abstinence-only-until-marriage programs that advocate for delaying sexual intercourse until marriage. These programs focus on changing adolescents' beliefs toward abstinence until marriage; however, it is unclear whether adolescents' beliefs about abstinence predict their sexual behavior, including sexual risk behavior (SRB). An alternative approach may be encouraging youth to delay their sexual debut until they reach the age of maturity, but not necessarily until marriage.

Methods: To address this question, we compare …

Cerebellar Deep Brain Stimulation As A Dual-Function Therapeutic For Restoring Movement And Sleep In Dystonic Mice, Luis E Salazar Leon, Linda H Kim, Roy V Sillitoe

Duncan NRI Faculty and Staff Publications

Dystonia arises with cerebellar dysfunction, which plays a key role in the emergence of multiple pathophysiological deficits that range from abnormal movements and postures to disrupted sleep. Current therapeutic interventions typically do not simultaneously address both the motor and non-motor symptoms of dystonia, underscoring the necessity for a multi-functional therapeutic strategy. Deep brain stimulation (DBS) is effectively used to reduce motor symptoms in dystonia, with existing parallel evidence arguing for its potential to correct sleep disturbances. However, the simultaneous efficacy of DBS for improving sleep and motor dysfunction, specifically by targeting the cerebellum, remains underexplored. Here, we test the effect …
