Effect Of Cannabidiol And ∆9-Tetrahydrocannabinol Concentration On Breast Cancer Cell Viability, Dorothy Achiaa Agyemang

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

-Tetrahydrocannabinol (THC) and cannabidiol (CBD) are phytocannabinoids that have a potential impact in cancer treatments. Studies have shown that certain cannabinoids cause cancer cells to die, but only with selective concentrations, which have not been well documented. The first study of this thesis was to determine the exact concentration of CBD and THC needed to kill human MCF-7 breast cancer cells rather than create mass multiplication leading to more growth of the cancer. To conduct this experiment, cell culture was performed with a MCF-7 breast cancer cell line. The treatment groups were treated with CBD or THC at varying concentrations …

Cytokine plays an important role in the inflammatory response against coronavirus infection. However, in severely ill patients with COVID-19, an excessive amount of cytokine serum level (cytokine storm) has been associated with the aggravation of coronavirus disease leading to acute respiratory distress syndrome (ARDS). Thus, the management of the cytokine storm could be the key to …

A Mini Review : Clinically Significant Potential Drug-Drug Interactions In Covid-19 And Comorbid Therapy, Ana Khusnul Faizah, Nani Wijayanti Dyah Nurrahman, Oki Nugraha Putra

Pharmaceutical Sciences and Research

Coronavirus disease 2019 (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and can be aggravated by comorbid diseases. In administering COVID-19 therapy, we need to consider potential drug-drug interactions (pDDIs) with comorbid drugs. Most patients with comorbid diseases get polypharmacy, therefore the risk of pDDIs increases. Potential drug-drug interactions can cause unwanted effects such as toxicity to death. There is no on-label therapy for COVID-19 but FDA has Emergency Use Authorization (EUA) for hydroxychloroquine, chloroquine, azithromycin, remdesivir, ritonavir, and lopinavir. Some COVID-19 treatment potential drug-drug interactions have a level of severity C and D, so …

Prion Protein Lowering Is A Disease-Modifying Therapy Across Prion Disease Stages, Strains And Endpoints, Eric Vallabh Minikel, Hien T. Zhao, Jason Le, Jill O'Moore, Rose Pitstick, Samantha Graffam, George A. Carlson, Michael P. Kavanaugh

Biomedical and Pharmaceutical Sciences Faculty Publications

Lowering of prion protein (PrP) expression in the brain is a genetically validated therapeutic hypothesis in prion disease. We recently showed that antisense oligonucleotide (ASO)-mediated PrP suppression extends survival and delays disease onset in intracerebrally prion-infected mice in both prophylactic and delayed dosing paradigms. Here, we examine the efficacy of this therapeutic approach across diverse paradigms, varying the dose and dosing regimen, prion strain, treatment timepoint, and examining symptomatic, survival, and biomarker readouts. We recapitulate our previous findings with additional PrP-targeting ASOs, and demonstrate therapeutic benefit against four additional prion strains. We demonstrate that

Hybrid Cyclic/Linear Peptides In A Multi-Component Lipid Structure As A Sirna Delivery System, Abdulaziz Alasmari

Pharmaceutical Sciences (MS) Theses

Delivering siRNA is challenging due to many obstacles, such as extremely short in vivo half-life, rapid elimination via glomerular filtration, and inability to cross cell membranes due to the hydrophilic and negatively-charged nature. Thus, a delivery system is needed to deliver the siRNA into the cells by crossing the negatively-charged phospholipid cell membrane. The goal of this project was to design hybrid cyclic-linear peptides as siRNA delivery system. We designed and synthesized hybrid cyclic-linear peptides [R5K]W5, [R6K]W6, and [R5K]W7 containing positively-charged arginine residues attached to hydrophobic tryptophan chains for more efficient interaction with siRNA and to improve siRNA internalization into …

Sex-Specific Modulation Of Blood Pressure And The Renin-Angiotensin System By Ace (Angiotensin-Converting Enzyme) 2, Hong Ji, Aline M. De Souza, Bilkish Bajaj, Wei Zheng, Xie Wu, Robert C. Speth, Kathryn Sandberg

HPD Articles

We showed ACE (angiotensin-converting enzyme) 2 is higher in the kidney of male compared with female mice. To further investigate this sex difference, we examined the role of ACE2 in Ang-[1-8] (angiotensin [1-8])-induced hypertension and regulation of the renin-angiotensin system in the kidney of WT (wild type) and Ace2 KO (knockout) mice. Mean arterial pressure rose faster in WT male than WT female mice after Ang-[1-8] infusion. This sex difference was attenuated in ACE2 KO mice. Ang-[1-8] infusion reduced glomerular AT1R (angiotensin type 1 receptor) binding in WT female mice by 30%, and deletion of abolished this effect. In contrast, …

Brazeau, Kristopher Attwood, Calvin J. Meaney, Gregory E. Wilding, Joseph D. Consiglio, Shirley S. Chang, Aijaz Gundroo, Rocco C. Venuto, Louise Cooper, Kathleen M. Tornatore

Pharmaceutical Science and Research

Interpatient variability in tacrolimus pharmacokinetics is attributed to metabolism by cytochrome P-450 3A5 (CYP3A5) isoenzymes and membrane transport by P-glycoprotein. Interpatient pharmacokinetic variability has been associated with genotypic variants for both CYP3A5 or ABCB1. Tacrolimus pharmacokinetics was investigated in 65 stable Black and Caucasian post-renal transplant patients by assessing the effects of multiple alleles in both CYP3A5 and ABCB1. A metabolic composite based upon the CYP3A5 polymorphisms: ^∗3(rs776746), ^∗6(10264272), and ^∗7(41303343), each independently responsible for loss of protein expression was used to classify patients as extensive, intermediate and poor metabolizers.
