Background: Treatment-related changes may occur due to radiation and temozolomide in glioblastoma and can mimic tumor progression on conventional MRI. DCE-MRI enables quantification of the extent of blood-brain barrier (BBB) disruption, providing information about areas of suspicious postcontrast T1 enhancement. We compared DCE-MRI processing methods for distinguishing true disease progression from pseudoprogression in high-grade gliomas (HGGs).

Methods: We identified 110 patients with HGG treated with surgery and chemoradiation who underwent DCE-MRI to further interrogate areas of new/increasing enhancement. All patients had confirmatory surgery/biopsy with pathology-confirmed progression or pseudoprogression. Scans were performed at 3T and analyzed using nordicICE. The MCA, SSS, …

Innovative therapies such as thermoembolization are expected to play an important role in improving care for patients with diseases such as hepatocellular carcinoma. Thermoembolization is a minimally invasive strategy that combines thermal ablation and embolization in a single procedure. This approach exploits an exothermic chemical reaction that occurs when an acid chloride is delivered via an endovascular route. However, comprehension of the complexities of the biophysics of thermoembolization is challenging. Mathematical models can aid in understanding such complex processes and assisting clinicians in making informed decisions. In this study, we used a Hagen-Poiseuille 1D blood flow model to predict the …

Desmoid tumors are rare mesenchymal neoplasms characterized by a clonal proliferation of fibroblasts and myofibroblasts. Using the novel contrast-enhanced susceptibility-weighted imaging (CE-SWI) for characterizing desmoid tumors can enhance the separation between fibrous T2-hypointense and cellular T1-enhancing components. We aim to evaluate the effectiveness of the CE-SWI signal, volumetric, and radiomics-derived features in assessing desmoid treatment response. This IRB-approved study included 17 single-lesion extremity desmoid fibromatosis patients who underwent standard-of-care MRI, including CE-SWI, from March 2021 to February 2024. Measurements of maximum diameter, volume, and the modified Choi (m-Choi: tumor/muscle T2 ratio) were computed based on CE-SWI and T2-STIR volumetric tumor …

Cardiovascular Manifestations Of Pseudoxanthoma Elasticum., Aimee Willett, Vivek V Jasti, Sean M Muir, Jay Anderson

Ambulatory and Primary Care Articles

Pseudoxanthoma elasticum (PXE) is a rare systemic disorder of elastic fibers. The most common manifestations include characteristic papules and ocular angioid streaks. Cardiovascular complications include peripheral arterial disease, hypertension, premature coronary artery disease, and cerebrovascular disease. These associations are secondary to dystrophic elastic fibers, resulting in the calcification of small- to medium-sized arteries. We present the case of a 22-year-old otherwise healthy female patient diagnosed with PXE following a biopsy of a neck lesion. Ophthalmologic evaluation revealed characteristic angioid streaks. The patient also reported early satiety and leg cramping, which prompted referral to gastroenterology and cardiology. Further investigation raised concern …

Protocol To Detect M22g Modification On Single Trna Iso-Decoders By Immuno-Northern Blotting, Sseu-Pei Hwang, Katherine Barondeau, Catherine Denicourt

Faculty, Staff and Student Publications

tRNA modifications are highly dynamic and play crucial roles in regulating gene expression. Here, we present an assay for analyzing N2, N2-dimethylguanosine (m22G) modifications on tRNAs using an antibody-based detection approach. We describe steps for isolating tRNAs from human cells via ion-exchange chromatography, capturing specific tRNA iso-decoders on streptavidin magnetic beads, and detecting modifications through immuno-northern blotting. This approach enables researchers to investigate other tRNA modifications using specific antibodies or downstream approaches such as mass spectrometry.

Memantine Inhibits Calcium-Permeable Ampa Receptors, Elisa Carrillo, Alejandra Montaño Romero, Cuauhtemoc U Gonzalez, Andreea L Turcu, Santiago Vázquez, Edward C Twomey, Vasanthi Jayaraman

Faculty, Staff and Student Publications

Memantine is an US Food and Drug Administration (FDA) approved drug that is thought to selectively inhibit NMDA-subtype of ionotropic glutamate receptors (NMDARs). NMDARs enable calcium influx into neurons and are critical for normal brain function. However, increasing evidence shows that calcium influx in neurological diseases is augmented by calcium-permeable AMPA-subtype ionotropic glutamate receptors (AMPARs). Here, we demonstrate that these calcium-permeable AMPARs (CP-AMPARs) are inhibited by memantine. Electrophysiology unveils that memantine inhibition of CP-AMPARs is dependent on their calcium permeability and the presence of their neuronal auxiliary subunit transmembrane AMPAR regulatory proteins (TARPs). Through cryo-electron microscopy we elucidate that memantine …

Targeting drugs to cancer cells via overexpressed cell-surface receptors has emerged as an effective therapeutic strategy for several cancers. However, identifying cell-surface receptors that allow selective uptake of targeting ligands by cancer cells—while sparing normal cells—remains a challenge, especially for triple-negative breast cancer (TNBC), which lacks a well-defined receptor for targeted delivery. In this study, immunohistochemical (IHC) analysis revealed that human TNBC patient tissues have significantly higher levels of keratin 1 (K1) compared to normal breast tissues. Among TNBC tissues, grade 3 tumors showed significantly higher (threefold) K1 expression compared to grade 2 tumors. We analyzed human TNBC and normal …

Faculty, Staff and Students Publications

Synthetic biology has enabled the development of biosensors to detect intestinal inflammation, yet few target the clinically validated biomarker of intestinal inflammation calprotectin with both diagnostic and therapeutic capabilities. Here, an optimized calprotectin biosensor is presented that leverages a zinc uptake regulator (Zur) controlled promoter coupled with a memory circuit to detect and record intestinal inflammation in vivo. The level of biosensor activation strongly correlates with calprotectin levels in the colon of two independent mouse models of colitis. Coupling of the biosensor with the production of the anti-inflammatory cytokine IL10 allowed for the resolution of chemically induced colitis, demonstrating the …

Enzyme-Independent Functions Of Hdac3 In The Adult Hear, Sichong Qian, Chen Zhang, Wenbo Li, Shiyang Song, Guanqiao Lin, Zixiu Cheng, Wenjun Zhou, Huiqi Yin, Yueli Wang, Haiyang Li, Ying H Shen, Zheng Sun

Center on Aging Staff Publications

The cardioprotective effects of histone deacetylase (HDAC) inhibitors (HDIs) are at odds with the deleterious effects of HDAC depletion. Here, we use HDAC3 as a prototype HDAC to address this contradiction. We show that adult-onset cardiac-specific depletion of HDAC3 in mice causes cardiac hypertrophy and contractile dysfunction on a high-fat diet (HFD), excluding developmental disruption as a major reason for the contradiction. Genetically abolishing HDAC3 enzymatic activity without affecting its protein level does not cause cardiac dysfunction on HFD. HDAC3 depletion causes robust downregulation of lipid oxidation/bioenergetic genes and upregulation of antioxidant/anti-apoptotic genes. In contrast, HDAC3 enzyme activity abolishment causes …

Interferon-gamma release assays (IGRAs) that evaluate an individual’s T-cell activation response to Mycobacterium tuberculosis (M.tb)-specific peptides serve an important role in diagnosing tuberculosis (TB). However, there are substantial challenges to the use of IGRAs in resource-limited settings. Further, IGRA diagnostic performance can also be compromised in anergic individuals. Here we describe a microfluidic chip-based antigen-specific T-cell response assay (ASTRA) that automates the detection of M.tb-specific T-cell activation responses to facilitate screening for latent M.tb infection and TB. We observe that ASTRA demonstrates high specificity for M.tb infection in independent patient cohorts. Compared with IGRA, ASTRA shows greater …
