Gender Differences In Urothelial Bladder Cancer: Effects Of Natural Killer Lymphocyte Immunity, Charles T. Lutz, Lydia Livas, Steven R. Presnell, Morgan Sexton, Peng Wang

Pathology and Laboratory Medicine Faculty Publications

Men are more likely to develop cancer than women. In fact, male predominance is one of the most consistent cancer epidemiology findings. Additionally, men have a poorer prognosis and an increased risk of secondary malignancies compared to women. These differences have been investigated in order to better understand cancer and to better treat both men and women. In this review, we discuss factors that may cause this gender difference, focusing on urothelial bladder cancer (UBC) pathogenesis. We consider physiological factors that may cause higher male cancer rates, including differences in X chromosome gene expression. We discuss how androgens may promote …

Examining Food Security, Choices And Barriers Among Community Supported Agriculture Participants During Covid- 19 In Kentucky, Martha J. Biddle, Junghee Kang, Julie Derringer, Anna Rose, Dawn Brewer, Misook L. Chung, Terry A. Lennie, Gia Mudd-Martin, Timothy A. Woods

UK CARES Faculty Publications

The coronavirus disease (COVID-19) pandemic is challenging food security. Our study’s purpose was to examine relationships among food security status, eating patterns and perceived barriers to food choices among shareholders (N = 209) in a Community Supported Agriculture (CSA) program during stay- at-home restrictions due to the pandemic. The food insecure group (n = 33) reported lower consumption of fruits/vegetables, whole grains and greater consumption of fast foods and more barriers to food choices compared to the food secure group (p < .05). A low food insecure proportion (16%) among the CSA participants suggests a potential role of a CSA program to prevent food insecurity.

Interleukin-10 Suppression Enhances T-Cell Antitumor Immunity And Responses To Checkpoint Blockade In Chronic Lymphocytic Leukemia., J R Rivas, Y Liu, S S Alhakeem, J M Eckenrode, F Marti, J P Collard, Y Zhang, K A Shaaban, N Muthusamy, G C Hildebrandt, L Chen, J S Thorson, M Leggas, Subbarao Bondada

Microbiology, Immunology, and Molecular Genetics Faculty Publications

T-cell dysfunction is a hallmark of B-cell Chronic Lymphocytic Leukemia (CLL), where CLL cells downregulate T-cell responses through regulatory molecules including programmed death ligand-1 (PD-L1) and Interleukin-10 (IL-10). Immune checkpoint blockade (ICB) aims to restore T-cell function by preventing the ligation of inhibitory receptors like PD-1. However, most CLL patients do not respond well to this therapy. Thus, we investigated whether IL-10 suppression could enhance antitumor T-cell activity and responses to ICB. Since CLL IL-10 expression depends on Sp1, we utilized a novel, better tolerated analogue of the Sp1 inhibitor mithramycin (MTM

Androgen Receptor Signaling In Prostate Cancer And Therapeutic Strategies, Aasems Jacob, Rishi Raj, Derek B. Allison, Zin W. Myint

Markey Cancer Center Faculty Publications

Understanding of the molecular mechanisms of prostate cancer has led to development of therapeutic strategies targeting androgen receptor (AR). These androgen-receptor signaling inhibitors (ARSI) include androgen synthesis inhibitor-abiraterone and androgen receptor antagonists-enzalutamide, apalutamide, and darolutamide. Although these medications provide significant improvement in survival among men with prostate cancer, drug resistance develops in nearly all patients with time. This could be through androgen-dependent or androgen-independent mechanisms. Even weaker signals and non-canonical steroid ligands can activate AR in the presence of truncated AR-splice variants, AR overexpression, or activating mutations in AR. AR splice variant, AR-V7 is the most studied among these and …
