A Single Cell Genomics Atlas Of The Drosophila Larval Eye Reveals Distinct Photoreceptor Developmental Timelines, Komal Kumar Bollepogu Raja, Kelvin Yeung, Yoon-Kyung Shim, Yumei Li, Rui Chen, Graeme Mardon

Faculty, Staff and Students Publications

The Drosophila eye is a powerful model system to study the dynamics of cell differentiation, cell state transitions, cell maturation, and pattern formation. However, a high-resolution single cell genomics resource that accurately profiles all major cell types of the larval eye disc and their spatiotemporal relationships is lacking. Here, we report transcriptomic and chromatin accessibility data for all known cell types in the developing eye. Photoreceptors appear as strands of cells that represent their dynamic developmental timelines. As photoreceptor subtypes mature, they appear to assume a common transcriptomic profile that is dominated by genes involved in axon function. We identify …

Faculty, Staff and Student Publications

The US Black population has higher colorectal cancer (CRC) incidence rates and worse CRC survival than the US White population, as well as historically lower rates of CRC screening. The Surveillance, Epidemiology, and End Results incidence rate data in people diagnosed between the ages of 20 and 45 years, before routine CRC screening is recommended, were analyzed to estimate temporal changes in CRC risk in Black and White populations. There was a rapid rise in rectal and distal colon cancer incidence in the White population but not the Black population, and little change in proximal colon cancer incidence for both …

An Uncommon Diagnosis Of Necrotizing Mastoiditis Presenting As Bell’S Palsy: A Case Report, Parker Maddox, Claire Abramoff

Student Papers, Posters & Projects

Introduction: The benign nature of Bell’s palsy has led to a lack of a standardized work-up, and dangerous underlying mimics are at risk of being missed. Case

Report: An 84-year-old female with a history of vertigo presented to the emergency department with a left-sided facial droop consistent with Bell’s palsy. After further work-up, the patient was diagnosed with bilateral necrotizing mastoiditis.

Conclusion: Unilateral facial weakness involving the forehead and palpebral fissures is often diagnosed as idiopathic Bell’s palsy. Various pathologies can present with unilateral facial weakness, and the differential needs to remain broad.

Pericentrin Deficiency In Smooth Muscle Cells Augments Atherosclerosis Through Hsf1-Driven Cholesterol Biosynthesis And Perk Activation, Suravi Majumder, Abhijnan Chattopadhyay, Jamie M Wright, Pujun Guan, L Maximilian Buja, Callie S Kwartler, Dianna M Milewicz

Faculty, Staff and Student Publications

Microcephalic osteodysplastic primordial dwarfism type II (MOPDII) is caused by biallelic loss-of-function variants in pericentrin (PCNT), and premature coronary artery disease (CAD) is a complication of the syndrome. Histopathology of coronary arteries from patients with MOPDII who died of CAD in their 20s showed extensive atherosclerosis. Hyperlipidemic mice with smooth muscle cell-specific (SMC-specific) Pcnt deficiency (PcntSMC-/-) exhibited significantly greater atherosclerotic plaque burden compared with similarly treated littermate controls despite similar serum lipid levels. Loss of PCNT in SMCs induced activation of heat shock factor 1 (HSF1) and consequently upregulated the expression and activity of HMG-CoA reductase (HMGCR), the rate-limiting enzyme …

Approximately 30% of early-stage lung adenocarcinoma patients present with disease progression after successful surgical resection. Despite efforts of mapping the genetic landscape, there has been limited success in discovering predictive biomarkers of disease outcomes. Here we performed a systematic multi-omic assessment of 143 tumors and matched tumor-adjacent, histologically-normal lung tissue with long-term patient follow-up. Through histologic, mutational, and transcriptomic profiling of tumor and adjacent-normal tissue, we identified an inflammatory gene signature in tumor-adjacent tissue as the strongest clinical predictor of disease progression. Single-cell transcriptomic analysis demonstrated the progression-associated inflammatory signature was expressed in both immune and non-immune cells, and cell …

Oncology Articles

The neutrophil to lymphocyte ratio (NTLR) and absolute lymphocyte count (ALC) recovery are prognostic across many cancers. We investigated whether NLTR predicts SBRT success or survival in a metastatic sarcoma cohort treated with SBRT from 2014 and 2020 (N = 42). Wilcox Signed Rank Test and Friedman Test compare NTLR changes with local failure vs. local control (N = 138 lesions). Cox analyses identified factors associated with overall survival. If local control was successful, NLTR change was not significant (p = 0.30). However, NLTR significantly changed in patients with local failure (p = 0.027). The multivariable Cox model demonstrated higher …

Pharmacotherapies Targeting Gaba-Glutamate Neurotransmission For Treatment-Resistant Depression, Courtney M Vecera, Alan C Courtes, Gregory Jones, Jair C Soares, Rodrigo Machado-Vieira

Faculty, Staff and Student Publications

Treatment-resistant depression (TRD) is a term used to describe a particular type of major depressive disorder (MDD). There is no consensus about what defines TRD, with various studies describing between 1 and 4 failures of antidepressant therapies, with or without electroconvulsive therapy (ECT). That is why TRD is such a growing concern among clinicians and researchers, and it explains the necessity for investigating novel therapeutic targets beyond conventional monoamine pathways. An imbalance between two primary central nervous system (CNS) neurotransmitters, L-glutamate and γ-aminobutyric acid (GABA), has emerged as having a key role in the pathophysiology of TRD. In this …
