A New Era Of Morphological Investigations: Reviewing Methods For Comparative Anatomical Studies, K. L. Ford, J. S. Albert, A. P. Summers, B. P. Hedrick, E. R. Schachner, A. S. Jones, K. Evans, P. Chakrabarty

School of Medicine Faculty Publications

The increased use of imaging technology in biological research has drastically altered morphological studies in recent decades and allowed for the preservation of important collection specimens alongside detailed visualization of bony and soft-tissue structures. Despite the benefits associated with these newer imaging techniques, there remains a need for more "tra- ditional"methods of morphological examination in many comparative studies. In this paper, we describe the costs and benefits of the various methods of visualizing, examining, and comparing morphological structures. There are significant differences not only in the costs associated with these different methods (monetary, time, equipment, and software), but also in …

Acute Acat1/Soat1 Blockade Increases Mam Cholesterol And Strengthens Er-Mitochondria Connectivity., Taylor C Harned, Radu V Stan, Ze Cao, Rajarshi Chakrabarti, Henry N Higgs, Catherine C Y Chang, Ta Yuan Chang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Cholesterol is a key component of all mammalian cell membranes. Disruptions in cholesterol metabolism have been observed in the context of various diseases, including neurodegenerative disorders such as Alzheimer's disease (AD). The genetic and pharmacological blockade of acyl-CoA:cholesterol acyltransferase 1/sterol O-acyltransferase 1 (ACAT1/SOAT1), a cholesterol storage enzyme found on the endoplasmic reticulum (ER) and enriched at the mitochondria-associated ER membrane (MAM), has been shown to reduce amyloid pathology and rescue cognitive deficits in mouse models of AD. Additionally, blocking ACAT1/SOAT1 activity stimulates autophagy and lysosomal biogenesis; however, the exact molecular connection between the ACAT1/SOAT1 blockade and these observed benefits remain …

Estimated Impact Of Low Isolate Numbers On The Reliability Of Cumulative Antibiogram Data, Christian Tran, John Hargy, Bryan Hess, Matthew Pettengill

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Antibiograms are cumulative reports of antimicrobial susceptibility results that are used to guide the selection of empirical antibiotic therapy. Although Clinical and Laboratory Standards Institute (CLSI) guidelines recommend including only organisms that have at least 30 isolates in an antibiogram, previous studies demonstrated that adherence to this recommendation is highly variable. This paper aims to model the impact of small sample sizes on expected levels of error in cumulative antibiograms by comparing percent susceptibility results for random samples to those of the larger, entire data set. The results demonstrate relatively high error rates when utilizing low numbers of isolates in …

Journal Articles: Genetics, Cell Biology & Anatomy

Porous alginate (Alg) hydrogels possess many advantages as cell carriers. However, current pore generation methods require either complex or harsh fabrication processes, toxic components, or extra purification steps, limiting the feasibility and affecting the cellular survival and function. In this study, a simple and cell-friendly approach to generate highly porous cell-laden Alg hydrogels based on two-phase aqueous emulsions is reported. The pre-gel solutions, which contain two immiscible aqueous phases of Alg and caseinate (Cas), are cross-linked by calcium ions. The porous structure of the hydrogel construct is formed by subsequently removing the Cas phase from the ion-cross-linked Alg hydrogel. Those …

Gurumurthy, Hinrich Staecker, Xuezhong Liu, Zheng-Yi Chen

Journal Articles: Genetics, Cell Biology & Anatomy

Patients with mutations in the TMPRSS3 gene suffer from recessive deafness DFNB8/DFNB10. For these patients, cochlear implantation is the only treatment option. Poor cochlear implantation outcomes are seen in some patients. To develop biological treatment for TMPRSS3 patients, we generated a knockin mouse model with a frequent human DFNB8 TMPRSS3 mutation. The Tmprss3^A306T/A306T homozygous mice display delayed onset progressive hearing loss similar to human DFNB8 patients. Using AAV2 as a vector to carry a human TMPRSS3 gene, AAV2-hTMPRSS3 injection in the adult knockin mouse inner ear results in TMPRSS3 expression in the hair cells and the spiral ganglion neurons. …

Complexity Of Progranulin Mechanisms Of Action In Mesothelioma, Elisa Ventura, Christopher Xie, Simone Buraschi, Antonino Belfiore, Renato V. Iozzo, Antonio Giordano, Andrea Morrione

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Background: Mesothelioma is an aggressive disease with limited therapeutic options. The growth factor progranulin plays a critical role in several cancer models, where it regulates tumor initiation and progression. Recent data from our laboratories have demonstrated that progranulin and its receptor, EphA2, constitute an oncogenic pathway in bladder cancer by promoting motility, invasion and in vivo tumor formation. Progranulin and EphA2 are expressed in mesothelioma cells but their mechanisms of action are not well defined. In addition, there are no data establishing whether the progranulin/EphA2 axis is tumorigenic for mesothelioma cells.

Methods: The expression of progranulin in various mesothelioma cell …

Nursing Considerations For Post-Traumatic Amnesia After A Traumatic Brain Injury, Hannah Grant

Senior Honors Theses

A period known as post-traumatic amnesia (PTA) often follows a traumatic brain injury (TBI). PTA is characterized by anterograde and retrograde amnesia, confusion, disorientation, and agitation. The duration and severity of PTA is a key indicator of the long-term prognosis after a TBI, so proper assessment and nursing care of a PTA patient is crucial. TBIs range from mild to severe, but primarily affect the fronto-temporal lobes. In PTA, both neural lesions and white matter damage within the parahippocampal region can cause PTA. A nurse must perform a thorough assessment of a TBI patient, but, since PTA is a key …

Data Supporting The Roles Of Bap1, Sting, And Ifn-Β In Isgf3 Activation In Ccrcc, Lauren E Langbein, Eleonora Sementino, Zhijiu Zhong, Wei Jiang, Li Li, Joseph R Testa, Haifeng Yang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The data presented in this article are companion materials to our manuscript titled "BAP1 maintains HIF-dependent interferon beta induction to suppress tumor growth in clear cell renal cell carcinoma" (Langbein et al., 2022), where we investigated the downstream effects of BAP1 (BRCA1-associated protein 1) expression in clear cell renal cell carcinoma (ccRCC) cell lines and mouse xenograft models. In the manuscript, we showed that BAP1 upregulates STING (stimulator of interferon genes) expression and activity in ccRCC cells, leading to IFN-β transcription and activation of interferon stimulated gene factor 3 (ISGF3), the transcription factor that mediates the effects of type I …

Altered Expression Of Glycobiology-Related Genes In Parkinson’S Disease Brain, Jay S Schneider, Garima Singh

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The precise mechanisms initiating and perpetuating the cellular degeneration in Parkinson's disease (PD) remain unclear. There is decreased expression of the main brain gangliosides, and GM1 ganglioside in particular, in the PD brain along with decreased expression of the genes coding for the glycosyltranferase and the sialyltransferase responsible for the synthesis of these brain gangliosides. However, potentially important pathogenic mechanisms contributing to the neurodegeneration in PD may also include altered levels of expression of genes involved in glycosylation, sialylation and sphingolipid synthesis and metabolism. Although various studies have described pathological lipid and glycolipid changes in PD brain, there have been …

Observations: We report three patients, 75-92 years old, presenting with corneal edema and dispersed, degenerated calcific lens material in the anterior chamber and vitreous 20-30 years after cataract surgery. In all patients, calcific particles studded the posterior surface of the cornea in a gravity-dependent distribution without apparent inflammation and were associated with localized corneal edema. In one patient, calcific particles were also associated with secondary open angle glaucoma. Deposits originated from the calcified …

Pi3k Isoform-Specific Regulation Of Leader And Follower Cell Function For Collective Migration And Proliferation In Response To Injury, Morgan D Basta, A. Menko, Janice L Walker

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

To ensure proper wound healing it is important to elucidate the signaling cues that coordinate leader and follower cell behavior to promote collective migration and proliferation for wound healing in response to injury. Using an ex vivo post-cataract surgery wound healing model we investigated the role of class I phosphatidylinositol-3-kinase (PI3K) isoforms in this process. Our findings revealed a specific role for p110α signaling independent of Akt for promoting the collective migration and proliferation of the epithelium for wound closure. In addition, we found an important role for p110α signaling in orchestrating proper polarized cytoskeletal organization within both leader and …

Bap1 Maintains Hif-Dependent Interferon Beta Induction To Suppress Tumor Growth In Clear Cell Renal Cell Carcinoma., Lauren Langbein, Rayan El Hajjar, Shen He, Eleonora Sementino, Zhijiu Zhong, Wei Jiang, Benjamin E Leiby, Li Li, Robert G Uzzo, Joseph R Testa, Haifeng Yang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BRCA1-associated protein 1 (BAP1) is a deubiquitinase that is mutated in 10-15% of clear cell renal cell carcinomas (ccRCC). Despite the association between BAP1 loss and poor clinical outcome, the critical tumor suppressor function(s) of BAP1 in ccRCC remains unclear. Previously, we found that hypoxia-inducible factor 2α (HIF2α) and BAP1 activate interferon-stimulated gene factor 3 (ISGF3), a transcription factor activated by type I interferons and a tumor suppressor in ccRCC xenograft models. Here, we aimed to determine the mechanism(s) through which HIF and BAP1 regulate ISGF3. We found that in ccRCC cells, loss of the von Hippel-Lindau tumor suppressor (VHL) …
