Faculty, Staff and Students Publications

Background: Approximately 20% of all transient ischaemic attacks (TIAs) and ischaemic strokes occur within the posterior circulation, with vertebrobasilar stenosis identified as the cause in roughly 25% of the cases. Studies have shown that about a quarter of these patients have atherosclerotic stenosis of at least 50% of the vertebrobasilar artery. Stenosis has been shown to be associated with an increased risk of 90-day recurrent vertebrobasilar stroke, particularly in the first few weeks, which is significantly higher when compared with patients with stenosis of the anterior circulation. Therefore, aggressive treatment is important for the patient's prognosis. Stenting is emerging as …

The cerebellar ventricular zone (VZ) is the primary source of progenitors that generate cerebellar GABAergic neurons, including Purkinje cells (PCs) and interneurons (INs). This study provides detailed characterization of human cerebellar GABAergic neurogenesis using transcriptomic and histopathological analyses and reveals conserved and unique features compared to rodents. We show that the sequential progression of neurogenesis is conserved and occurs before 8 postconception weeks. Notably, PC differentiation occurs in the outer subventricular zone (SVZ), a region absent in the mouse cerebellum. Human PCs are generated during a compact two-week period before the onset of cerebral cortex histogenesis. A subset of human …

The Potential Of Brain Organoids In Addressing The Heterogeneity Of Synucleinopathies, Xiao-Jun Diao, Claudio Soto, Fei Wang, Yu Wang, Yun-Cheng Wu, Abhisek Mukherjee

Faculty, Staff and Student Publications

Synucleinopathies are a group of diseases characterized by neuronal and glial accumulation of α-synuclein (aSyn) linked with different clinical presentations, including Parkinson's disease (PD), Parkinson's disease with dementia (PDD), Dementia with Lewy Bodies (DLB) and Multiple system atrophy (MSA). Interestingly, the structure of the aSyn aggregates can vary across different synucleinopathies. Currently, it is unclear how the aSyn protein can aggregate into diverse structures and affect distinct cell types and various brain regions, leading to different clinical symptoms. Recent advances in induced pluripotent stem cells (iPSCs)-based brain organoids (BOs) technology provide an unprecedented opportunity to define the etiology of synucleinopathies …

Glioblastoma (GBM) is an aggressive primary brain cancer with few effective therapies. Stereotactic needle biopsies are routinely used for diagnosis; however, the feasibility and utility of investigative biopsies to monitor treatment response remains ill-defined. Here, we demonstrate the depth of data generation possible from routine stereotactic needle core biopsies and perform highly resolved multi-omics analyses, including single-cell RNA sequencing, spatial transcriptomics, metabolomics, proteomics, phosphoproteomics, T-cell clonotype analysis, and MHC Class I immunopeptidomics on standard biopsy tissue obtained intra-operatively. We also examine biopsies taken from different locations and provide a framework for measuring spatial and genomic heterogeneity. Finally, we investigate the …

Rural-Urban Disparities In Hospitalisation For Myocardial Infarction In Systemic Lupus Erythematosus In The Usa, Jasvinder A Singh, Sumanth Chandrupatla

Faculty, Staff and Students Publications

Objective: To assess whether rural-urban disparities exist in people with SLE for hospitalisation with myocardial infarction (MI).

Methods: We used the 2016-2019 US National Inpatient Sample data that contain all hospitalisation data. In people with a diagnosis of SLE, we assessed the multivariable adjusted ORs (aORs) to examine the association of rural patient residence with MI hospitalisation, while adjusting for demographics, payer, income, hospital characteristics and the Deyo-Charlson Comorbidity Index.

Results: We found that the crude rates of patients hospitalised with MI per 100 000 area specific SLE hospitalisations were higher in rural versus urban residents with SLE, 2265 versus …

Mitochondrial Dysfunction And Parkinson's Disease: A Critical Link, Anika J. Millar

Senior Honors Theses

Parkinson’s disease is a neurodegenerative disorder, caused by the damage to and death of dopamine-releasing neurons in the brain. The substantia nigra is a major region housing dopaminergic neurons and plays a critical role in motor and cognitive function. When these neurons are compromised, dopamine levels decline, leading to the development of motor and cognitive dysfunction. Current treatments include dopamine precursors, which help to replace dopamine and relieve motor symptoms. However, while there is symptomatic treatment for Parkinson’s disease, there are no preventative therapies or cures. A potential link between mitochondrial dysfunction and Parkinson’s disease has prompted further research. Investigating …

Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infections in infants, young children, and immunocompromised individuals. Currently, FDA-approved monoclonal antibody therapies are limited to infants and young children with severe RSV disease. As a result, there is an urgent need for comprehensive studies of RSV pathogenesis to support the development of new therapeutic strategies. Exchange proteins directly activated by cAMP (EPAC) have recently emerged as key regulators in various viral infections. Our previous work identified EPAC isoform 2 (EPAC2) as a critical factor in RSV replication and host innate immune responses. However, …

Patients with high-grade serous ovarian carcinoma (HGSC) are usually diagnosed with advanced-stage disease, and the tumors often have immunosuppressive characteristics. Together, these factors are important for disease progression, drug resistance, and mortality. In this study, we used a combination of single-cell sequencing and spatial transcriptomics to identify the molecular mechanisms that lead to immunosuppression in HGSC. Primary tumors consistently showed a more active immune microenvironment than did omental tumors. In addition, we found that untreated primary tumors were mostly populated by dysfunctional CD4 and CD8 T cells in later stages of differentiation; this, in turn, was correlated with expression changes …

Current treatments for advanced prostate cancer (PCa) primarily target the androgen receptor (AR) pathway. However, the emergence of castration-resistant prostate cancer (CRPC) and resistance to AR pathway inhibitors (APPIs) remains ongoing challenges. Here, we present BSJ-5-63, a proteolysis-targeting chimera (PROTAC) targeting cyclin-dependent kinases (CDKs) CDK12, CDK7, and CDK9, offering a multipronged approach to CRPC therapy. BSJ-5-63 degrades CDK12, diminishing BRCA1 and BRCA2 expression and inducing a sustained "BRCAness" state. This sensitizes cancer cells to PARP inhibitors (PARPis) regardless of their homologous recombination repair (HRR) status. Furthermore, CDK7 and CDK9 degradation attenuates AR signaling, enhancing its therapeutic efficacy. Preclinical studies, including …

Ovarian cancer is associated with high rates of patient mortality and morbidity. Laparoscopic assessment of tumor localization can be used for treatment planning in newly diagnosed high-grade serous ovarian carcinoma (HGSOC). While spread to multiple intra-abdominal areas is correlated with worse outcomes, whether other morphological tumor differences are also associated with patient outcomes is unknown. Given the large volume of visual information in laparoscopic videos, we investigated whether deep-learning models can capture implicit features and predict treatment outcomes. We developed a novel deep-learning framework using pre-treatment laparoscopic images to assess clinical outcomes following upfront standard treatment, defined as short progression-free …

Starting at middle age, adults often suffer from visceral adiposity and associated adverse metabolic disorders. Lineage tracing in mice revealed that adipose progenitor cells (APCs) in visceral fat undergo extensive adipogenesis during middle age. Thus, despite the low turnover rate of adipocytes in young adults, adipogenesis is unlocked during middle age. Transplantations quantitatively showed that APCs in middle-aged mice exhibited high adipogenic capacity cell-autonomously. Single-cell RNA sequencing identified a distinct APC population, the committed preadipocyte, age-enriched (CP-A), emerging at this age. CP-As demonstrated elevated proliferation and adipogenesis activity. Pharmacological and genetic manipulations indicated that leukemia inhibitory factor receptor signaling was …

Hepatic Manifestations Following Gene Therapy, Akash Roy, Shalini Bansal, Anand Kulkarni, K. Rajender Reddy

SKMC Student Presentations and Publications

Gene therapy involves the introduction of genetic materials, most commonly using viral vectors, to alter gene expression to ameliorate or cure disease symptoms with minimal adverse events. While interest in gene therapy has been on the increase, concerns have arisen about the potential for hepatotoxicity, which arises from diverse mechanisms. While viral vectors can produce dose-dependent hepatotoxicity secondary to integration, immune responses appear to be the primary driving mechanism. A mild increase in aminotransferases is the most common hepatic manifestation, occurring variably in 20%-80%, while there has been rare progress to acute liver failure. The occurrence of hepatotoxicity is unpredictable …

Identification of isocitrate dehydrogenase (IDH) mutations has uncovered the crucial role of metabolism in gliomagenesis. Oncolytic herpes virus (oHSV) initiates direct tumor debulking by tumor lysis and activates anti-tumor immunity, however, little is known about the role of glioma metabolism in determining oHSV efficacy. Here we identify that oHSV rewires central carbon metabolism increasing glucose utilization towards oxidative phosphorylation and shuttling glutamine towards reductive carboxylation in IDH wildtype glioma. The switch in metabolism results in increased lipid synthesis and cellular ROS. PKC induces ACSL4 in oHSV treated cells leading to lipid peroxidation and ferroptosis. Ferroptosis is critical to launch an …
