Lysosomes are cytoplasmic organelles central for the degradation of macromolecules to maintain cellular homoeostasis and health. However, how lysosomal activity can be boosted to counteract ageing and ageing-related diseases remains elusive. Here we reveal that silencing specific vacuolar H+-ATPase subunits (for example, vha-6), which are essential for intestinal lumen acidification in Caenorhabditis elegans, extends lifespan by ~60%. This longevity phenotype can be explained by an adaptive transcriptional response typified by induction of a set of transcripts involved in lysosomal function and proteolysis, which we termed the lysosomal surveillance response (LySR). LySR activation is characterized by boosted lysosomal activity …

Purpose: Immune checkpoint inhibitors (ICI) have limited efficacy in pleural mesothelioma. We investigated the role of Dickkopf WNT signaling pathway inhibitor 3 (DKK3) in overcoming treatment resistance.

Patients and methods: We performed preclinical studies to elucidate DKK3's role in ICI-resistant mouse mesothelioma. Based on these findings, we conducted a single-arm, phase II clinical trial of a combination of Ad-SGE-DKK3 and nivolumab for chemotherapy-refractory epithelioid pleural mesothelioma, with the objective response rate as the primary outcome.

Results: DKK3 was significantly reduced in human epithelioid mesothelioma. Overexpression of DKK3 in cancer cells activated the p53 pathway, enhanced glycolysis, increased surface PD-L1, and …

Cardiovascular-Kidney-Metabolic Effects: Steroidal And Nonsteroidal Mineralocorticoid Receptor Antagonists, Biykem Bozkurt, James L Januzzi, Shweta Bansal

Faculty, Staff and Students Publications

Cardiovascular (CV)-kidney-metabolic (CKM) syndrome is a complex disorder characterized by the co-occurrence of CV risk factors, including chronic kidney disease (CKD), hypertension, and metabolic dysfunction, which creates a vicious cycle where one factor negatively impacts the others, ultimately leading to poor overall CV and kidney outcomes. Overactivation of the mineralocorticoid receptor, through binding with aldosterone and ligand-independent mechanisms, is implicated in the pathogenesis of CKM; mineralocorticoid receptor antagonists (MRAs) can block this interaction. Steroidal MRAs are currently recommended for people with heart failure (HF) with reduced ejection fraction and hypertension; however, the role of nonsteroidal MRAs in CKM is evolving. …

Faculty, Staff and Students Publications

Inadvertent intracranial nasogastric tube placement is a recognized risk following skull base fracture, but prior skull base surgery also poses a significant and underrecognized risk for this potentially fatal complication. We report the case of a 75-year-old female admitted with Clostridioides difficile colitis, six months after endoscopic endonasal resection of a pituitary macroadenoma. A systematic review identified 10 prior cases of intracranial tube placement following skull base or sinonasal surgery, including nasotracheal and feeding tube insertions. Literature suggests that using small-bore flexible tubes and preserving anatomical barriers, such as the position of the middle turbinate and intact bony structures like …

Microbial Biosensor For Sensing And Treatment Of Intestinal Inflammation, Duolong Zhu, Jeffrey Galley, Jason Pizzini, Elena Musteata, Martin V Douglas, Walter J Chazin, Eric P Skaar, Jeffrey J Tabor, Robert A Britton

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 …

Faculty, Staff and Students Publications

Introduction: Chronic ocular graft-versus-host disease (oGVHD) is one of the most common complications after allogeneic hematopoietic stem cell transplantation (aHSCT). Recent studies indicate that desiccating stress by air-conditioning in transplantation wards increases the incidence of oGVHD. To test the hypothesis that experimental desiccating stress is a risk factor for oGVHD a mouse model of oGVHD was subjected to experimental desiccating stress.

Materials/methods: A previously established chemo-induced minor-mismatch mouse model of oGVHD was used. One group was challenged with desiccating stress for 18 days and compared to non-desiccated GVHD animals. Clinical phenotyping was performed weekly and ocular tissue and regional lymph …

Childhood Obesity Body Mass Index And Gut Microbiome: A Cluster Randomized Controlled Pilot Feasibility Study, Marilyn Frenn, Nita Salzman, Vy Lam, Mary Holtz, Andrea Moosreiner, Mauricio Garnier-Villarreal, Maharaj Singh

College of Nursing Faculty Research and Publications

Background:

Prebiotic fiber has been examined as a way to foster gut bacteria less associated with obesity. Tests of prebiotic fiber in reducing obesity have occurred mainly in animals, adults, and Caucasians when the highest obesity rates are in African American and Latinx youth. Response to prebiotic fiber is determined by the pre-existing intestinal microbiota. The type of microbiota varies based on diet and physical activity (PA), so it is important to examine acceptability and response to prebiotic fiber in those most at risk for obesity.

Methods:

This cluster randomized controlled feasibility trial included an online program designed to improve …

Metabolomic Data May Support The Development Of Personalized Nutrition Approaches To Type 2 Diabetes Management, Danielle J Lee, Shragvi Balaji, Jerome I Rotter, Alexis C Wood

Faculty, Staff and Students Publications

Diet is a major modifiable risk factor for type 2 diabetes (T2D), and suboptimal diets continue to contribute substantially to the population burden of T2D. Personalized nutrition proponents argue that specializing recommendations to interindividual differences in diet-health relationships will yield reductions in disease risk. However, how to personalize diet, and to whom, to reduce T2D risk remains unclear. Metabolites offer promise in this respect, as they capture (in part) dietary intake after the processes of digestion, processing, and absorption. The incorporation of metabolite data into diet-health studies therefore offers the opportunity to examine how the effects of food on the …

2020-Current year OA Pubs

Osteosarcoma (OS) is a rapidly progressive primary malignant bone tumor that occurs in children and adolescents aged between 15 and 19 years and adults aged over 60 years. As alternative splicing (AS) changes caused by abnormal splicing factors contribute to tumor progression, gene expression and AS analyses were performed on 44 osteosarcoma patients to create a genome-wide co-expression network of RNA-binding proteins (RBPs), AS events, and AS genes. A gain- or loss-of-function osteosarcoma cell model was established, and an interactive network analysis and enrichment analysis were performed. Karyopherin Subunit Alpha 2 (KPNA2) negatively correlated with patient survival. KPNA2 transports splicing …

Liger-Hn Phase Iii Trials Of Petosemtamab + Pembrolizumab And Petosemtamab Monotherapy In Recurrent Or Metastatic Hnscc, Jean-Pascal Machiels, Douglas Adkins, Et Al.

2020-Current year OA Pubs

Patients with recurrent/metastatic (r/m) head and neck squamous cell carcinoma (HNSCC) have limited treatment options and a dismal prognosis, especially when their cancer is resistant to standard treatments like anti-programmed cell death protein 1 and platinum-based therapies. Petosemtamab - a human, common light chain, bispecific antibody with enhanced antibody-dependent cellular cytotoxicity targeting epidermal growth factor receptor (EGFR) and leucine-rich repeat-containing G-protein coupled receptor 5 (LGR5) - demonstrated antitumor activity in r/m HNSCC. In many tumor types, including HNSCC, EGFR is an oncogenic driver, while LGR5 is upregulated. LGR5 can potentiate the wingless-type integration site (WNT)/β-catenin signaling pathway in response to …

Projection-Tags Enable Multiplex Projection Tracing And Multi-Modal Profiling Of Projection Neurons, Lite Yang, Fang Liu, Hannah Hahm, Takao Okuda, Xiaoyue Li, Yufen Zhang, Vani Kalyanaraman, Monique R Heitmeier, Vijay K Samineni

2020-Current year OA Pubs

Single-cell multiomic techniques have sparked immense interest in developing a comprehensive multi-modal map of diverse neuronal cell types and their brain-wide projections. However, investigating the complex wiring diagram, spatial organization, transcriptional, and epigenetic landscapes of brain-wide projection neurons is hampered by the lack of efficient and easily adoptable tools. Here we introduce Projection-TAGs, a retrograde AAV platform that allows multiplex tagging of projection neurons using RNA barcodes. By using Projection-TAGs, we performed multiplex projection tracing of the cortex and high-throughput single-cell profiling of the transcriptional and epigenetic landscapes of the cortical projection neurons in female mice. Projection-TAGs can be leveraged …

Department of Neurology Faculty Papers

The basis and impact of functional asymmetries in the brain, particularly language lateralization, are not fully understood, and the relationship between functional and structural asymmetries remains largely untested. This study investigated the degree to which asymmetries in hemispheric language laterality are concordant with asymmetries in gray matter (GM) structure and whether the hemispheric organization of memory is influenced by functional language asymmetries. Structural and functional MR data was acquired from 261 individuals, including those with unilateral temporal lobe epilepsy (LTLE = 96, RTLE = 69) and matched with healthy participants (HPs = 96). Functional language laterality indices (LIs) were calculated …

Department of Neurology Faculty Papers

Temporal lobe epilepsy (TLE) is the most common focal epilepsy, with focal to bilateral tonic-clonic seizures (FBTCS+) a more severe form of the disorder. Evidence has underscored the critical role of the thalamus, mesial temporal region, basal ganglia and cerebellum, along with the cortex, in the propagation, termination, and modulation of seizure activity. We examined time variant patterns of interaction within and between 7 cortical and 4 subcortical systems in 55 healthy controls and 56 patients with TLE (n = 40 with FBTCS+ and 15 without), isolating those patterns most distinctive of FBTCS+ utilizing tools from dynamic network neuroscience on …
