Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a common genetic disease that leads to progressive renal cyst growth and loss of renal function, and is caused by mutations in the genes encoding polycystin-1 (PC1) and polycystin-2 (PC2), respectively. The PC1/PC2 complex localizes to primary cilia and can act as a flow-dependent calcium channel in addition to numerous other signaling functions. The exact functions of the polycystins, their regulation and the purpose of the PC1/PC2 channel are still poorly understood. PC1 is an integral membrane protein with a large extracytoplasmic N-terminal domain and a short, ~200 amino acid C-terminal cytoplasmic tail. …

Long-Acting Antiretroviral Nanoformulation Development And Subcellular Trafficking, Dongwei Guo

Theses & Dissertations

The introduction of nanoformulated antiretroviral therapeutic regimens is a promising alternative to standard once a day oral treatment of HIV infection. Our lab has pioneered this effort and was successful in harnessing mononuclear phagocytes (monocytes, dendritic cells and macrophages) as nanoformulated drug carriers. The approach was developed as Trojan horses for drug transport, delivery and distribution to sites of viral replication in order to facilitate microbial elimination in HIV sanctuaries. However, the remaining challenges for current antiretroviral nanoformulations include to formulate a broad range of hydrophilic short-acting drugs, and to elucidate the mechanism of sequestered nanoparticles in macrophages at the …

Stability And Kinetics Of Dna Pseudoknots: Formation Of T∗A•T Base-Triplets And Their Targeting Reactions, Calliste Steffensmeier

Theses & Dissertations

Pseudoknots have been found to play important roles in the biology of RNA. These stem-loop motifs are considered to be very compact and the targeting of their loops with complementary strands is accompanied with lower favorable free energy terms. We used a combination of spectroscopic (UV, CD and fluorescence), calorimetric (DSC, PPC and ITC) and kinetic (SPR) techniques to investigate: 1) Local base-triplet formation in pseudoknots; 2) energetic contributions for the association of pseudoknots with their complementary strands; and 3) the kinetic rates as a function of targeting strand length.

We investigated a set of DNA pseudoknots with sequence: d(TCTCT …

A series of cyclic peptides containing a number of tryptophan (W) and glutamic acid (E) residues were synthesized and evaluated as pH-sensitive agents for targeting of acidic tissue and pH-dependent cytoplasmic delivery of molecules. Biophysical studies revealed the molecular mechanism of peptides action and localization within the lipid bilayer of the membrane at high and low pHs. The symmetric, c[(WE)4WC], and asymmetric, c[E4W5C], cyclic peptides translocated amanitin, a polar cargo molecule of similar size, across the lipid bilayer and induced cell death in a pH- and concentration-dependent manner. Fluorescently-labelled peptides were evaluated for targeting of acidic 4T1 mammary tumors in …

Rnai Nanotechnology: A Platform For Sirna Screening And Cancer Gene Therapy, Mayurbhai Ravikant Patel

Seton Hall University Dissertations and Theses (ETDs)

Over the past two decades, advances in RNA structural biology have improved our understanding of the structures and folding properties of naturally occurring RNAs. RNA sequences and structures participate in many specific biological functions, such as those performed by messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), micro RNA (miRNA), short-interfering RNA (siRNA), small nuclear RNA (snRNA) and many others. The noncoding RNAs, such as siRNA, do not express proteins but have been utilized in a wide range of applications, including RNA interference (RNAi) and the regulation of mRNA expression. These important biological functions have been implemented in gene …

Extracorporeal Delivery Of A Therapeutic Enzyme, Chun Zhang, Jun Pu, Xiaolan Yang, Tao Feng, Fang Liu, Deqiang Wang, Xiaolei Hu, Ang Gao, Hongbo Liu, Chang-Guo Zhan, Fei Liao

Molecular Modeling and Biopharmaceutical Center Faculty Publications

To remove circulating harmful small biochemical(s)/substrates causing/deteriorating certain chronic disease, therapeutic enzyme(s) delivered via vein injection/infusion suffer(s) from immunoresponse after repeated administration at proper intervals for a long time and short half-lives since delivery. Accordingly, a novel, generally-applicable extracorporeal delivery of a therapeutic enzyme is proposed, by refitting a conventional hemodialysis device bearing a dialyzer, two pumps and connecting tubes, to build a routine extracorporeal blood circuit but a minimal dialysate circuit closed to circulate the therapeutic enzyme in dialysate. A special quantitative index was derived to reflect pharmacological action and thus pharmacodynamics of the delivered enzyme. With hyperuricemic blood …

Design, Optimization, And Characterization Of Novel Polymer-Based Formulations For Controlled Release Of Drugs, Mario Alberto Cano Vega

Open Access Theses

Pharmaceutical products are a key aspect of treatment and prevention of disease. For example, dibenzazepine (DBZ) is a drug that has proved to be useful for the treatment of obesity while progesterone is a common drug for hormonal replacement therapy in women. However, administration of these drugs by conventional dosage forms offers little control over the drug distribution and concentration in the body and often result in unintended adverse consequences on other cells/tissues.

Recent advances in nanotechnology and polymer science have enabled the design and development of controlled release systems that would allow spatiotemporal delivery of drugs with improved efficacy. …

Biosimilar Naming Conventions: Pharmacist Perceptions And Impact On Confidence In Dispensing Biologics, Daniel M. Tomaszewski

Pharmacy Faculty Articles and Research

BACKGROUND: The approval of the first biosimilar in the United States has placed increased pressure on the FDA to provide guidance on the naming convention that will be assigned to current and future biosimilars. The release of the FDA draft guidance on nonproprietary naming of biosimilars in August 2015 established a naming convention for all biologic products, including biosimilars. However, the draft guidance is nonbinding while the FDA continues to receive input from stakeholders, and it does not address the naming convention that will be used for products designated as interchangeable biologics.

OBJECTIVES: To (a) determine pharmacist perceptions …

Repeated Zolpidem Treatment Effects On Sedative Tolerance, Withdrawal, Mrna Levels, And Protein Expression, Brittany T. Wright

Theses and Dissertations (ETD)

Zolpidem and benzodiazepines (BZs) potentiate the inhibitory action of gamma-Aminobutyric acid (GABA) by allosterically binding to GABAA receptors (GABAAR). Prolonged use of GABAAR positive allosteric modulators (PAM) can lead to behavioral tolerance, the diminished response to the same drug dose with repeated use, and withdrawal, a group of symptoms that occur due to abrupt end of drug treatment. Zolpidem is a short-acting, non-BZ GABAAR PAM whose potential for tolerance and withdrawal is unclear. Zolpidem demonstrates sedative efficacy similar to BZs and has become a main treatment of insomnia in lieu of BZs. Zolpidem replaced BZs due to lower incidences of …

Discoveries Of Targets And Novel Agents For The Treatment Of Ischemic Retinopathy And Neovascular Disease, Jordan Javad Toutounchian

Theses and Dissertations (ETD)

Diabetic retinopathy (DR) and age-related macular degeneration (AMD) are among the most common causes of blindness in adults. Vision loss can occur during the advanced stages of DR and AMD as a consequence of unregulated and dysfunctional growth of new blood vessels, or neovascularization (NV) in the retina or choroid. NV can also be triggered by numerous other ocular insults and diseases including radiation retinopathy (RR) and retinal vein occlusion. These latter cases are generally less common but, like DR and AMD, they are characterized by an initial injury, chronic inflammation, and ischemia which perpetuates episodes of retinal neovascularization (RNV). …
