Functional Interplay Between Chromatin Remodeling Complexes Rsc, Swi/Snf And Iswi In Regulation Of Yeast Heat Shock Genes, Tamara Y. Erkina, Y. Zou, S. Freeling, V. I. Vorobyev, Alexander M. Erkine

Scholarship and Professional Work – COPHS

Chromatin remodeling is an essential part of transcription initiation. We show that at heat shock gene promoters functional interactions between individual ATP-dependent chromatin remodeling complexes play critical role in both nucleosome displacement and Pol II recruitment. Using HSP12, HSP82 and SSA4 gene promoters as reporters, we demonstrated that while inactivation of SNF2, a critical ATPase of the SWI/SNF complex, primarily affects the HSP12 promoter, depletion of STH1- a SNF2 homolog from the RSC complex reduces histone displacement and abolishes the Pol II recruitment at all three promoters. From these results, we conclude that redundancy between SWI/SNF and RSC complexes …

Mandatory Pharmacy Residencies: One Way To Reduce Medication Errors, Rami B. Ibrahim, Lilian Baghat-Ibrahim, David J. Reeves

Scholarship and Professional Work – COPHS

We read with disbelief about a newly graduated pharmacist dispensing 30 times the amount of injectable sodium bicarbonate intended, an error that led to a patient’s death.1 As clinicians, we wondered what clinical scenario might mandate the large amount of sodium bicarbonate dispensed—the answer was none. So why did the pharmacist dispense it? The answer is all too clear: With rare exceptions, institutional pharmacists nationwide are largely focused on dispensing. Postgraduate clinical training in the basic aspects of pharmacotherapy is scarce and not viewed as essential. Inadequate pharmacist training and a staffing shortage were suggested as contributing to the …

Pharmacists' Rating Of Relevance Of Available Information In Deciding The Validity Of Opioid Medication Prescriptions, Leonardo Roberto Torres

Electronic Theses and Dissertations

Pharmacists are tasked with making decisions regarding the validity of prescriptions. Some have proposed factors that should be considered when evaluating a prescription's validity. Yet, there is little known about the decision process that pharmacists employ at the time of dispensing and what information pharmacists deem relevant in that decision-making process. Using an online survey instrument, a sample of community pharmacists were divided into three groups and presented with a prescription scenario. They were asked to rate the relevance of information, which is proposed to be appropriate and inappropriate, available at the time of dispensing. They were asked to consider …

Role Of Transforming Growth Factor Beta In Corneal Function, Biology And Pathology, Ashish Tandon, Jonathan C. K. Tovey, Ajay Sharma, Rangan Gupta, Rajiv R. Mohan

Pharmacy Faculty Articles and Research

Transforming growth factor-beta (TGFβ) is a pleiotropic multifunctional cytokine that regulates several essential cellular processes in many parts of the body including the cornea. Three isoforms of TGFβ are known in mammals and the human cornea expresses all of them. TGFβ1 has been shown to play a central role in scar formation in adult corneas whereas TGFβ2 and TGFβ3 have been implicated to play a critical role in corneal development and scarless wound healing during embryogenesis. The biological effects of TGFβ in the cornea have been shown to follow SMAD dependent as well as SMAD-independent signaling pathways depending upon cellular …

Chemosensitization Of Cancer Cells By Sirna Using Targeted Nanogel Delivery, Erin B. Dickerson, William H. Blackburn, Michael H. Smith, Laura B. Kapa, L. Andrew Lyon, John F. Mcdonald

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Background: Chemoresistance is a major obstacle in cancer treatment. Targeted therapies that enhance cancer cell sensitivity to chemotherapeutic agents have the potential to increase drug efficacy while reducing toxic effects on untargeted cells. Targeted cancer therapy by RNA interference (RNAi) is a relatively new approach that can be used to reversibly silence genes in vivo by selectively targeting genes such as the epidermal growth factor receptor (EGFR), which has been shown to increase the sensitivity of cancer cells to taxane chemotherapy. However, delivery represents the main hurdle for the broad development of RNAi therapeutics.

Methods: We report here …

Expression Of The Intestinal Biomarkers Guanylyl Cyclase C And Cdx2 In Poorly Differentiated Colorectal Carcinomas., Brody Winn, Rosemarie Tavares, Andres Matoso, Lelia Noble, Jacqueline Fanion, Scott A Waldman, Murray B Resnick

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Guanylyl cyclase C, a receptor for bacterial diarrheagenic enterotoxins, is expressed selectively by intestinal epithelium and is an endogenous downstream target of CDX2. The expression of Guanylyl cyclase C is preserved throughout the adenoma/carcinoma sequence in the colorectum. Detection of Guanylyl cyclase C expression by reverse transcriptase-polymerase chain reaction is currently being validated as a technique to identify occult lymph node metastases in patients with colorectal cancer and for circulating cells in the blood for postoperative surveillance. Although Guanylyl cyclase C is widely expressed by well-differentiated colorectal cancer, its expression in poorly differentiated colorectal cancer has not been evaluated. A …

Computational Prediction And Analysis Of The Napp – Dr6 Interaction: Implications For Alzheimer's Research, Joseph Audie, Sergei Y. Ponomarev

Chemistry & Physics Faculty Publications

Alzheimer's disease (AD) is a progressive neurodegenerative disorder that involves a devastating clinical course and lacks an effective treatment. A biochemical model for neuronal development, recently proposed by Nikolaev and co-workers, hinges on a novel protein-protein interaction between the death cell receptor six (DR6) ectodomain and an N-terminal fragment of amyloid precursor protein (NAPP). The model provides a coherent and satisfying framework for better understanding AD pathophysiology. Moreover, the DR6-NAPP interaction offers a tempting target for novel pharmacological intervention. Given all of this, we constructed a structural model of the DR6-NAPP interaction using the neurotrophin p75 receptor as a template. …

Willingness To Influence Indication-Based Off-Label Prescribing: An Investigation Of Hospital Pharmacists, Ram Sankar Basak

Electronic Theses and Dissertations

Off-label prescribing is a comand legal practice in the United States. However, off-label prescribing occurs oftentimes with inadequate evidence of effectiveness. Such practice, especially when prescribing for disease conditions different from approved clinical indications (indication-based off-label prescribing), brings about controversy and raises different issues with various stakeholders. Although indication-based off-label prescribing offers advantages in terms of providing innovative therapy, it raises concerns because the safety and efficacy of such use may not be evaluated adequately. Thus, the objective of the study was to examine whether pharmacists are willing to influence physicians while evaluating an indication-based off-label medication order. Based on …

Fungi-Derived Natural Products With Binding Affinities For Human Opioid Or Cannabinoid Receptors, Jiangtao Gao

Electronic Theses and Dissertations

Both opioid and cannabinoid receptors belong to the large superfamily of GPCRs and play an important role in a variety of processes including pain, craving, neurodegeneration, metabolic regulation, anxiety and immune function. Therefore, recent advances and discoveries in opioid and cannabinoid receptors have paved the way for a very exciting future for opioid and cannabinoid receptors-based therapies to potentially treat a variety of conditions. However, the growing realizations of the complexity of these two receptors regulation in physiological and pathological conditions have discouraged the development of new therapeutics. So, it is important for us to identify new chemical scaffolds which …
