Implications Of Oligomeric Amyloid-Beta (Oaβ42) Signaling Through Α7Β2-Nicotinic Acetylcholine Receptors (Nachrs) On Basal Forebrain Cholinergic Neuronal Intrinsic Excitability And Cognitive Decline, Andrew A George, Jaime M Vieira, Cameron Xavier-Jackson, Michael T Gee, John R Cirrito, Heather A Bimonte-Nelson, Marina R Picciotto, Ronald J Lukas, Paul Whiteaker

2020-Current year OA Pubs

Neuronal and network-level hyperexcitability is commonly associated with increased levels of amyloid-β (Aβ) and contribute to cognitive deficits associated with Alzheimer's disease (AD). However, the mechanistic complexity underlying the selective loss of basal forebrain cholinergic neurons (BFCNs), a well-recognized characteristic of AD, remains poorly understood. In this study, we tested the hypothesis that the oligomeric form of amyloid-β (oAβ

In 2017, 46,157 and 3,127 new oropharyngeal cancer (OPC) cases were reported in the U.S. and Texas, respectively. About 70% of OPC were attributed to human papillomavirus (HPV). However, only 51% of U.S. and 43.5% of Texas adolescents have completed the HPV vaccine series. Therefore, modeling the demographic dynamics and transmission of HPV and OPC progression is needed for accurate estimation of the economic and epidemiological impacts of HPV vaccine in a geographic area. An age-structured population dynamic model was developed for the U.S. state of Texas. With Texas-specific model parameters calibrated, this model described the dynamics of HPV-associated OPC …

BACKGROUND: In August 2017, Hurricane Harvey caused unprecedented flooding across the greater Houston area. Given the potential for widespread flood-related exposures, including mold and sewage, and the emotional and mental toll caused by the flooding, we sought to evaluate the short- and long-term impact of flood-related exposures on the health of Houstonians. Our objectives were to assess the association of flood-related exposures with allergic symptoms and stress among Houston-area residents at two time points: within approximately 30 days (T1) and 12 months (T2) after Hurricane Harvey's landfall.

METHODS: The Houston Hurricane Harvey Health (Houston-3H) Study enrolled a total of 347 …

Sars-Cov-2 Infection Severity Is Linked To Superior Humoral Immunity Against The Spike, Jenna J Guthmiller, Ya-Nan Dai, Christopher A Nelson, Paige D Hall, Daved H Fremont, Et Al

Open Access Publications

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently causing a global pandemic. The antigen specificity of the antibody response mounted against this novel virus is not understood in detail. Here, we report that subjects with a more severe SARS-CoV-2 infection exhibit a larger antibody response against the spike and nucleocapsid protein and epitope spreading to subdominant viral antigens, such as open reading frame 8 and nonstructural proteins. Subjects with a greater antibody response mounted a larger memory B cell response against the spike, but not the nucleocapsid protein. Additionally, we revealed that antibodies against the spike are still capable …

The Circadian Cryptochrome, Cry1, Is A Pro-Tumorigenic Factor That Rhythmically Modulates Dna Repair., Ayesha A Shafi, Chris M Mcnair, Jennifer J Mccann, Mohammed Alshalalfa, Anton Shostak, Tesa M Severson, Yanyun Zhu, Andre Bergman, Nicolas Gordon, Amy C Mandigo, Saswati N Chand, Peter Gallagher, Emanuela Dylgjeri, Talya S Laufer, Irina A Vasilevskaya, Matthew J Schiewer, Michael Brunner, Felix Y Feng, Wilbert Zwart, Karen E Knudsen

Department of Cancer Biology Faculty Papers

Mechanisms regulating DNA repair processes remain incompletely defined. Here, the circadian factor CRY1, an evolutionally conserved transcriptional coregulator, is identified as a tumor specific regulator of DNA repair. Key findings demonstrate that CRY1 expression is androgen-responsive and associates with poor outcome in prostate cancer. Functional studies and first-in-field mapping of the CRY1 cistrome and transcriptome reveal that CRY1 regulates DNA repair and the G2/M transition. DNA damage stabilizes CRY1 in cancer (in vitro, in vivo, and human tumors ex vivo), which proves critical for efficient DNA repair. Further mechanistic investigation shows that stabilized CRY1 temporally regulates expression of genes required …

Multiwalled Carbon Nanotubes Co-Delivering Sorafenib And Epidermal Growth Factor Receptor Sirna Enhanced Tumor-Suppressing Effect On Liver Cancer., Zhili Wen, Yuliang Feng, Youwen Hu, Lingyan Lian, Hongyan Huang, Li Guo, Shanwen Chen, Qian Yang, Moran Zhang, Lijun Wan, Kedong Xu, Degejirifu, Xiaohua Yan

Faculty Research 2021

OBJECTIVE: This study aimed to investigate the effects of multiwalled carbon nanotubes (MWNTs) co-delivering sorafenib (Sor) and epidermal growth factor receptor (EGFR) siRNA (MWNT/Sor/siRNA) on tumor growth in liver cancer (LC).

RESULTS: MWNT/Sor/siRNA was proved to possess increased Sor release, high siRNA stability, and enhanced cellular uptake. In addition, MWNT treatment has few effects on cell proliferation and apoptosis in HepG2 cells; however, MWNT/Sor/siRNA treatment significantly inhibited clone number and induced cell apoptosis, which shows a more favorable antitumor effect than MWNT/Sor and free Sor and free siRNA in HepG2 cells. Moreover MWNT/Sor/siRNA treatment has the most significant antitumor effect …

Complete Mapping Of Mutations To The Sars-Cov-2 Spike Receptor-Binding Domain That Escape Antibody Recognition, Allison J. Greaney, Paul W. Rothlauf, Zhuoming Liu, Sean P. J. Whelan, Et Al.

2020-Current year OA Pubs

Antibodies targeting the SARS-CoV-2 spike receptor-binding domain (RBD) are being developed as therapeutics and are a major contributor to neutralizing antibody responses elicited by infection. Here, we describe a deep mutational scanning method to map how all amino-acid mutations in the RBD affect antibody binding and apply this method to 10 human monoclonal antibodies. The escape mutations cluster on several surfaces of the RBD that broadly correspond to structurally defined antibody epitopes. However, even antibodies targeting the same surface often have distinct escape mutations. The complete escape maps predict which mutations are selected during viral growth in the presence of …

Multicomponent lipid emulsions are available for critical care of preterm infants. We sought to determine the impact of different lipid emulsions on early priming of the host and its response to an acute stimulus. Pigs delivered 7d preterm (n = 59) were randomized to receive different lipid emulsions for 11 days: 100% soybean oil (SO), mixed oil emulsion (SO, medium chain olive oil and fish oil) including 15% fish oil (MO15), or 100% fish oil (FO100). On day 11, pigs received an 8-h continuous intravenous infusion of either lipopolysaccharide (LPS—lyophilized Escherichia coli) or saline. Plasma was collected for …

Frontiers In Human Factors: Embedding Specialists In Multi-Disciplinary Efforts To Improve Healthcare., Ken Catchpole, Paul Bowie, Sarah Fouquet, Joy Rivera, Sue Hignett

Manuscripts, Articles, Book Chapters and Other Papers

Despite the application of a huge range of human factors (HF) principles in a growing range of care contexts, there is much more that could be done to realize this expertise for patient benefit, staff well-being and organizational performance. Healthcare has struggled to embrace system safety approaches, misapplied or misinterpreted others, and has stuck to a range of outdated and potentially counter-productive myths even has safety science has developed. One consequence of these persistent misunderstandings is that few opportunities exist in clinical settings for qualified HF professionals. Instead, HF has been applied by clinicians and others, to highly variable degrees-sometimes …

The R-Enantiomer Of Ketorolac Reduces Ovarian Cancer Tumor Burden In Vivo, Martha M. Grimes, S Ray Kenney, Dayna R. Dominguez, Kathryn J. Brayer, Yuna Guo, Angela Wandinger-Ness, Laurie G. Hudson

Pathology Research and Scholarship

BACKGROUND: Rho-family GTPases, including Ras-related C3 botulinum toxin substrate 1 (Rac1) and cell division control protein 42 (Cdc42), are important modulators of cancer-relevant cell functions and are viewed as promising therapeutic targets. Based on high-throughput screening and cheminformatics we identified the R-enantiomer of an FDA-approved drug (ketorolac) as an inhibitor of Rac1 and Cdc42. The corresponding S-enantiomer is a non-steroidal anti-inflammatory drug (NSAID) with selective activity against cyclooxygenases. We reported previously that R-ketorolac, but not the S-enantiomer, inhibited Rac1 and Cdc42-dependent downstream signaling, growth factor stimulated actin cytoskeleton rearrangements, cell adhesion, migration and invasion in ovarian cancer cell lines and …

Small Molecule Sarm1 Inhibitors Recapitulate The Sarm1 -/- Phenotype And Allow Recovery Of A Metastable Pool Of Axons Fated To Degenerate, Robert O Hughes, Todd Bosanac, Xianrong Mao, Thomas M Engber, Aaron Diantonio, Jeffrey Milbrandt, Rajesh Devraj, Raul Krauss

Open Access Publications

Axonal degeneration is responsible for disease progression and accumulation of disability in many neurodegenerative conditions. The axonal degenerative process can generate a metastable pool of damaged axons that remain structurally and functionally viable but fated to degenerate in the absence of external intervention. SARM1, an NADase that depletes axonal energy stores upon activation, is the central driver of an evolutionarily conserved program of axonal degeneration. We identify a potent and selective small molecule isoquinoline inhibitor of SARM1 NADase that recapitulates the SARM1

Plasmid-Based Reverse Genetics For Probing Phosphorylation-Dependent Viroplasm Formation In Rotaviruses, Jeanette M Criglar, Sue E Crawford, Mary K Estes

Faculty, Staff and Students Publications

Rotavirus (RV) replication occurs in cytoplasmic compartments, known as viroplasms, that are composed of viral and cellular proteins. Viroplasm formation requires RV nonstructural proteins NSP2 and NSP5 and cellular lipid droplets (LDs); however, the mechanisms required for viroplasm assembly remain largely unknown. We previously identified two conformationally-distinct forms of NSP2 (dNSP2, vNSP2) found in RV-infected cells that interact differentially with hypo- and hyperphosphorylated NSP5, respectively, and indicate a coordinated phosphorylation-dependent mechanism regulating viroplasm assembly. We also reported that phosphorylation of dNSP2 on serine 313 by the cellular kinase CK1α triggers the localization of vNSP2 to sites of viroplasm assembly and …

Drug Repurposing For Targeting Cyclic Nucleotide Transporters In Acute Leukemias - A Missed Opportunity, Dominique R. Perez, Larry A. Sklar, Alexandre Chigaev, Ksenia Matlawska-Wasowska

Pediatrics Research and Scholarship

While current treatment regimens for acute leukemia can dramatically improve patient survival, there remains room for improvement. Due to its roles in cell differentiation, cell survival, and apoptotic signaling, modulation of the cyclic AMP (cAMP) pathway has provided a meaningful target in hematological malignancies. Several studies have demonstrated that gene expression profiles associated with increased pro-survival cAMP activity or downregulation of various pro-apoptotic factors associated with the cAMP pathway are apparent in acute leukemia patients. Previous work to increase leukemia cell intracellular cAMP focused on the use of cAMP analogs, stimulating cAMP production via transmembrane-associated adenylyl cyclases, or decreasing cAMP …
