Novel Therapy Targeting Mutant-Krasg12d And Galectin-1 In Pancreatic Cancer, 2023 The University of Texas Rio Grande Valley
Novel Therapy Targeting Mutant-Krasg12d And Galectin-1 In Pancreatic Cancer, Ana I. Martinez Bulnes, Nirnoy Dan, Poornima Devi Shaji, Swathi Holla, Murali M. Yallapu, Sheema Khan
Introduction: Although, surgical resection and chemotherapy are the gold standard for treating Pancreatic Ductal Adenocarcinoma (PDAC), low patient survival rate remains the problem. The activating point mutation of the KRAS on codon-12 is present in 70–95% of PDAC cases and so far, no success has been achieved to inhibit KRAS. KRASG12D regulates cell proliferation, differentiation, apoptosis. Recent preliminary and published studies show high Galectin-1 (Gal-1) levels in both pancreatic cancer and stromal cells, which modulate tumor microenvironment and metastasis. Additionally, genetic deletion of gal1 inhibits metastasis and improves survival in KRAS mouse model of PDAC (1). Therefore, our objective is …

Farber Institute for Neuroscience Faculty Papers
BACKGROUND: Active upper extremity (UE) assistive devices have the potential to restore independent functional movement in individuals with UE impairment due to neuromuscular diseases or injury-induced chronic weakness. Academically fabricated UE assistive devices are not usually optimized for activities of daily living (ADLs), whereas commercially available alternatives tend to lack flexibility in control and activation methods. Both options are typically difficult to don and doff and may be uncomfortable for extensive daily use due to their lack of personalization. To overcome these limitations, we have designed, developed, and clinically evaluated the NuroSleeve, an innovative user-centered UE hybrid orthosis.
METHODS: This …
Targeting Brd4 In The Treatment Of Pleural Fibrosis, 2023 University of Texas at Tyler
Targeting Brd4 In The Treatment Of Pleural Fibrosis, Joy Adewumi
Pleural fibrosis (PF) is a respiratory disorder that refers to the thickening and scarring of the pleura. Currently, there is a lack of pharmaceutic treatment options for PF. Pleural mesothelial to mesenchymal transition (MesoMT) is a critical process that contributes to the development of PF. Bromodomain-containing protein 4 (BRD4), a transcriptional and epigenetic regulator, has recently been implicated in a wide range of lung injuries. However, whether BRD4 is involved in regulating MesoMT and the development of PF remains unclear and was explored in this study. Primary human pleural mesothelial cells (HPMCs) were used to test the role of BRD4 …

Effects Of Interleukin-22 (Il-22) On Necroptosis, Inflammatory Responses, And Metabolism Of Mycobacterium Tuberculosis Stimulated Type 2 Diabetes Mellitus Mouse Macrophages, Bismark Owusu-Afriyie
Mycobacterium tuberculosis (Mtb) infects one-third of the world’s population and causes nearly 1.3 million deaths per year. Limited information is available about the immune responses during Mtb infection in type 2 diabetic hosts. Our laboratory developed an experimentally induced type 2 diabetes (T2DM) model in wild-type C57BL/6 mice and found that IL-22 and type 3 innate lymphoid cells (ILC3s) reduce inflammation and mortality of Mtb-infected T2DM mice. Our laboratory also found that Mtb-infected alveolar macrophages (AMs) from T2DM mice undergo necroptosis compared to Mtb-infected AMs of non-T2DM mice. In the current study, we determined whether …
Functional Impact Of Ethyl-Β-D-Glucuronide On Mycobacterium Tuberculosis Stimulated Lung Macrophages, 2023 University of Texas at Tyler
Functional Impact Of Ethyl-Β-D-Glucuronide On Mycobacterium Tuberculosis Stimulated Lung Macrophages, Charles Inaku
Chronic alcohol abuse has been shown to alter immune defense mechanisms in humans and mice which makes the host susceptible to infections, including Mycobacterium tuberculosis (Mtb) infection. However, limited information is available on the mechanisms involved in alcohol-mediated host immune system dysfunction.
In this study, we determined the effects of ethyl-β-d-glucuronide (EtG), an alcohol-derived metabolite, on immune response of mice lung macrophages. We measured cytokine and chemokine production by gamma-irradiated mtb (γ-mtb) stimulated mice lung macrophages in the presence or absence of EtG. We also determined the effect of EtG on the metabolic state of γ-mtb stimulated mice lung macrophages. …

Impact Of Lyophilization On Porcine Hemoglobin Properties., 2023 University of Louisville
Impact Of Lyophilization On Porcine Hemoglobin Properties., Mustafa Almosawi
College of Arts & Sciences Senior Honors Theses
Blood transfusion is the single most often performed lifesaving procedure in hospitals worldwide. Unfortunately, packed red blood cells (RBCs) used for transfusion can only be stored for 42 days at 4 °C before being discarded due to irreversible damage that occurs during storage. Any reduction in available RBCs for an extended period can lead to blood shortages. To increase the shelf-life of RBCs, we investigated freeze-drying (lyophilizing) in the presence of the non-toxic sugar trehalose as a method for long-term preservation. However, the oxidative stress of the lyophilization and storage processes can compromise the functionality of these cells, and the …
Jurisgenerative Tissues: Sociotechnical Imaginaries And The Legal Secretions Of 3d Bioprinting, 2023 Osgoode Hall Law School of York University
Jurisgenerative Tissues: Sociotechnical Imaginaries And The Legal Secretions Of 3d Bioprinting, Roxanne Mykitiuk, Joshua Shaw
Articles & Book Chapters
Three-dimensional ‘bioprinting’ is under development, which may produce living human organs and tissues to be surgically implanted in patients. Like tissue engineering and regenerative medicine generally, the process of bioprinting potentially disrupts experience of the human body by redefining understandings of, and becoming actualised in new practices and regimes in relation to, the body. The authors consider how these novel sociotechnical imaginaries may emerge, having regard to law’s contribution to, as well as its possible transformation by, the process of 3D bioprinting. The authors draw on Gilbert Simondon and corporeal, material feminists to account for these disruptions as ‘ontogenetic,’ in …

Radiological imaging techniques, including magnetic resonance imaging (MRI) and positron emission tomography (PET), are the standard-of-care non-invasive diagnostic approaches widely applied in neuro-oncology. Unfortunately, accurate interpretation of radiological imaging data is constantly challenged by the indistinguishable radiological image features shared by different pathological changes associated with tumor progression and/or various therapeutic interventions. In recent years, machine learning (ML)-based artificial intelligence (AI) technology has been widely applied in medical image processing and bioinformatics due to its advantages in implicit image feature extraction and integrative data analysis. Despite its recent rapid development, ML technology still faces many hurdles for its broader applications …
Screening Tcf19 And Kif18b To Determine Co-Regulation With Mybl1 In Triple Negative Breast Cancer Patient Tissues, 2022 Texas Southern University
Screening Tcf19 And Kif18b To Determine Co-Regulation With Mybl1 In Triple Negative Breast Cancer Patient Tissues, Tyra Sharda Ivory
The aggressive behavior in triple-negative breast cancer (TNBC) is due to genetic signaling events, which call for the comprehensive analyses of genes differentially regulated in the cancers. Our laboratory previously found that MYBL1 was over-expressed in a fraction of the TNBC, compared to some luminal, and other breast cancer subtypes. The MYBL1 gene is a proto-oncogene that serves as a strong transcriptional activator. The gene is involved in signaling events related to cell cycle signaling, differentiation, proliferation, and apoptosis, all which are differentially regulated in cancers. Because MYBL1 is a transcription regulator, involved in cancer-related mechanisms and differentially expressed in …
Activatable Synthetic Biomarker Systems For Gene- And Cell-Based Cancer Detection And Theranostics, 2022 The University of Western Ontario
Activatable Synthetic Biomarker Systems For Gene- And Cell-Based Cancer Detection And Theranostics, Tianduo Wang
Electronic Thesis and Dissertation Repository
Introduction: The ability to non-invasively detect cancer cells and other cell types within tumours has many valuable applications for early cancer diagnosis and grading, monitoring disease progression, and assessing treatment response. While technologies for detecting endogenous cancer biomarkers in bodily fluids or through imaging are being rapidly developed, they often face challenges that result in low sensitivity and/or specificity. To address these limitations, an emerging strategy involves building exogenously delivered tools that use reporter genes as synthetic biomarkers. Leveraging synthetic biology, reporter genes can be assembled into cancer-activatable gene circuits which link their expression to the presence of endogenous cancer …

Jefferson Institute of Molecular Medicine Papers and Presentations
Introduction: Clustered regularly interspaced short palindromic repeat and its associated protein (CRISPR-Cas)-based technologies generate targeted modifications in host genome by inducing site-specific double-strand breaks (DSBs) that can serve as a substrate for homology-directed repair (HDR) in both in vitro and in vivo models. HDR pathway could enhance incorporation of exogenous DNA templates into the CRISPR-Cas9-mediated DSB site. Owing to low rate of HDR pathway, the efficiency of accurate genome editing is diminished. Enhancing the efficiency of HDR can provide fast, easy, and accurate technologies based on CRISPR-Cas9 technologies. Methods: The current study presents an overview of attempts conducted on the …
