Pharmacy Faculty Articles and Research

Myocardial toxicity and drug resistance caused by drug efflux are major limitations of doxorubicin (Dox)-based chemotherapy. Dox structure modification could be used to develop conjugates with an improved biological profile, such as antiproliferative activity and higher cellular retention. Thus, Dox thiol conjugates, Dox thiol (Dox-SH), thiol-reactive Dox-SS-pyridine (SS = disulfide), and a Dox-SS-cell-penetrating cyclic peptide, Dox-SS-[C(WR)4K], were synthesized. Dox was reacted with Traut's reagent to generate Dox-SH. The thiol group was activated by the reaction with dithiodipyridine to afford the corresponding Dox-SS-Pyridine (Dox-SS-Pyr). A cyclic cell-penetrating peptide containing a cysteine residue [C(WR)4K] was prepared using Fmoc solid-phase strategy. Dox-SS-Py was …

Pharmacy Faculty Articles and Research

Hypoxia can induce chemoresistance, which is a significant clinical obstacle in cancer therapy. Here, we assessed development of hypoxia-induced chemoresistance (HICR) against free versus polymeric cisplatin micelles in a triple negative breast cancer cell line, MDA-MB-231. We then explored two strategies for the modulation of HICR against cisplatin micelles: a) the development of actively targeted micelles; and b) combination therapy with modulators of HICR in MDA-MB-231 cells. Actively targeted cisplatin micelles were prepared through surface modification of acetal-poly(ethylene oxide)-poly(-carboxyl-"-caprolactone) (acetal-PEO-PCCL) micelles with epidermal growth factor receptor (EGFR)-targeting peptide, GE11 (YHWYGYTPQNVI). Our results showed that hypoxia induced resistance against free and …

“Do We Know Jack” About Jak? A Closer Look At Jak/Stat Signaling Pathway, Emira Bousoik, Hamidreza Montazeri Aliabadi

Pharmacy Faculty Articles and Research

Janus tyrosine kinase (JAK) family of proteins have been identified as crucial proteins in signal transduction initiated by a wide range of membrane receptors. Among the proteins in this family JAK2 has been associated with important downstream proteins, including signal transducers and activators of transcription (STATs), which in turn regulate the expression of a variety of proteins involved in induction or prevention of apoptosis. Therefore, the JAK/STAT signaling axis plays a major role in the proliferation and survival of different cancer cells, and may even be involved in resistance mechanisms against molecularly targeted drugs. Despite extensive research focused on the …

Economic Burden Of Renal Cell Carcinoma (Rcc) And Treatment Patterns, Overall Survival And Healthcare Costs Among Older Metastatic Rcc Patients, Hrishikesh P. Kale

Theses and Dissertations

Background

Renal cell carcinoma (RCC) is the most common type of kidney cancer. Patients diagnosed with metastatic RCC (mRCC) have shorter overall survival compared to those diagnosed at earlier stages. Several targeted therapies, which cost from $7,000 - $16,000 per month have been approved since 2005 to treat mRCC. In addition, there is a growing interest in the use of cytoreductive nephrectomy (CN) with targeted therapies among mRCC patients. However, little is known regarding the economic burden of RCC and role of CN and prescribing patterns of targeted therapies among older mRCC patients.

1) To assess the economic burden …

Activity Of Distinct Growth Factor Receptor Network Components In Breast Tumors Uncovers Two Biologically Relevant Subtypes, Moom Roosan, Shelley M. Macneil, David F. Jenkins, Gajendra Shrestha, Sydney R. Wyatt, Jasmine A. Mcquerry, Stephen R. Piccolo, Laura M. Heiser, Joe W. Gray, W. Evan Johnson, Andrea H. Bild

Pharmacy Faculty Articles and Research

Background
The growth factor receptor network (GFRN) plays a significant role in driving key oncogenic processes. However, assessment of global GFRN activity is challenging due to complex crosstalk among GFRN components, or pathways, and the inability to study complex signaling networks in patient tumors. Here, pathway-specific genomic signatures were used to interrogate GFRN activity in breast tumors and the consequent phenotypic impact of GRFN activity patterns.

Methods
Novel pathway signatures were generated in human primary mammary epithelial cells by overexpressing key genes from GFRN pathways (HER2, IGF1R, AKT1, EGFR, KRAS (G12V), RAF1, BAD). The pathway analysis toolkit Adaptive Signature Selection …

Arteaga Ballesteros, Timothy Fu, Remant Bahadur Kc, Hamidreza Montazeri Aliabadi, Judith C. Hugh, Raimar Löbenberg, Hasan Uludag

Pharmacy Faculty Articles and Research

Conventional breast cancer therapies have significant limitations that warrant a search for alternative therapies. Short-interfering RNA (siRNA), delivered by polymeric biomaterials and capable of silencing specific genes critical for growth of cancer cells, holds great promise as an effective and more specific therapy. Here, we employed amphiphilic polymers and silenced the expression of two cell cycle proteins, TTK and CDC20, and the anti-apoptosis protein survivin to determine the efficacy of polymer-mediated siRNA treatment in breast cancer cells as well as side effects in non-malignant cells in vitro. We first identified effective siRNA carriers by screening a library of lipid-substituted polyethylenimines …

Phosphatidylinositol 3-Kinase (Pi3k) As A Therapeutic Target In Nsclc, Christopher W. Stamatkin

Theses and Dissertations--Pharmacy

Deregulated activation of phosphatidylinositol 3-kinase (PI3K) pathway is central to many human malignancies. The functions of this pathway are critical for normal cell metabolism, proliferation, and survival. In lung cancers, the PI3K pathway activity is often aberrantly driven by multiple mutations, including EGFR, KRAS, and PIK3CA. Molecules targeting the PI3K pathway are intensely investigated as potential anti-cancer agents. Although inhibitors of the pathway are currently in clinical trials, rational and targeted use of these compounds, alone or in combination, requires an understanding of isoform-specific activity in context. We sought to identify class IA PI3K enzyme (p110a/PIK3CA, p110b/PIK3CB, p110d/PIK3CD) activities using …

The production and in vitro evaluation of various polymers (PGCD, CHS and CHSg) microspheres for a RMT and RMT planning are described. Microparticles with a 30±10 µm size distribution were prepared by emulsion method. The in vitro half-life of the particles was determined in PBS buffer and porcine plasma and their potential …

Pharmacokinetic/Pharmacodynamic (Pk/Pd) Modeling Of Anti-Neoplastic Agents, Daniel Lexcen, Ahmed H. Salem, Walid F. Elkhatib, Virginia Haynes, Ayman Noreddin

Pharmacy Faculty Books and Book Chapters

"Development of tumor resistance to chemotherapeutics is related to inherent tumor variations regarding sensitivity to chemotherapeutics and to sub-optimal dosing regimens, including variation in patient pharmacokinetics that result in suboptimal exposure of tumor cells to anti-neoplastic drugs [1, 2]. The rate and extent of drug efficacy depends on the extent of drug exposure at the tumor site and the time above the effective concentration [3]. In vitro models that incorporate these pharmacokinetic and pharmacodynamic (PK/PD) principles to optimize therapeutic response may be considered the method of choice for optimizing dosing schedules before translating data from static assays to animals and …

Influence Of Oncotype Dx® On Chemotherapy Prescribing In Early Stage Breast Cancer Patients: A Claims-Based Evaluation Of Utilization In The Real World, Kenneth Neil Kennedy

Theses and Dissertations--Pharmacy

The decision for adjuvant therapy in women with early stage breast cancer (ESBC) has historically been guided by the presence or absence of specific biological markers (hormone and HER2 receptors), age, and extent of nodal involvement. Oncotype DX® is a validated assay that quantifies protein expression that can predict the risk of cancer recurrence. This study evaluates if the use of Oncotype DX® impacts chemotherapy prescribing in ESBC. This retrospective, cohort study identified patients with ESBC from a large commercially insured population from January 2007 through June 2009. Patients were identified as having ESBC by utilizing procedure and diagnosis codes …
