Targeted Delivery Of Bioactive Molecules For Vascular Intervention And Tissue Engineering, 2018 Worcester Polytechnic Institute
Targeted Delivery Of Bioactive Molecules For Vascular Intervention And Tissue Engineering, Hannah A. Strobel, Elisabet I. Qendro, Eben Alsberg, Marsha W. Rolle
Open Access Articles
Cardiovascular diseases are the leading cause of death in the United States. Treatment often requires surgical interventions to re-open occluded vessels, bypass severe occlusions, or stabilize aneurysms. Despite the short-term success of such interventions, many ultimately fail due to thrombosis or restenosis (following stent placement), or incomplete healing (such as after aneurysm coil placement). Bioactive molecules capable of modulating host tissue responses and preventing these complications have been identified, but systemic delivery is often harmful or ineffective. This review discusses the use of localized bioactive molecule delivery methods to enhance the long-term success of vascular interventions, such as drug-eluting stents ...

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 ...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency, one of the most common human genetic enzymopathies, is caused by over 160 different point mutations and contributes to the severity of many acute and chronic diseases associated with oxidative stress, including hemolytic anemia and bilirubin-induced neurological damage particularly in newborns. As no medications are available to treat G6PD deficiency, here we seek to identify a small molecule that corrects it. Crystallographic study and mutagenesis analysis identify the structural and functional defect of one common mutant (Canton, R459L). Using high-throughput screening, we subsequently identify AG1, a small molecule that increases the activity of the wild-type, the ...

Multidrug resistance protein 1 (MRP1) can efflux a wide variety of molecules including toxic chemicals, drugs, and their derivatives out of cells. Substrates of MRP1 include anti-cancer agents, antibiotics, anti-virals, anti-human immunodeficiency virus (HIV), and many other drugs. To identify novel substrates and modulators of MRP1 by exploiting intramolecular fluorescence resonance energy transfer (FRET), we genetically engineered six different two-color MRP1 proteins by changing green fluorescent protein (GFP) insertion sites, while keeping the red fluorescent protein (RFP) at the C-terminal of MRP1. Four of six recombinant proteins showed normal expression, localization, and transport activity. We quantified intramolecular FRET using ensemble ...

Composite, multifunctional fine particles are likely to be at the frontier of materials science in the foreseeable future. Here we present a submicron composite particle that mimics the stratified structure of the Earth by having a zero-valent iron core, a silicate/silicide mantle, and a thin carbonaceous crust resembling the biosphere and its biotic deposits. Particles were formulated in a stable colloidal form and made to interact with various types of healthy and cancer cells in vitro. A selective anticancer activity was observed, promising from the point of view of the intended use of the particles for tumor targeting across ...
Targeting Neuropeptides To Bone Fractures For Accelerated Healing, 2018 Purdue University
Targeting Neuropeptides To Bone Fractures For Accelerated Healing, Nicholas A. Young, Jeffery J. Nielsen, Philip S. Low
The Summer Undergraduate Research Fellowship (SURF) Symposium
In patients over the age of 65 especially, bone fractures represent a significant disease burden. Non-invasive drug therapies are not available for bone fractures which represents a problem for this population. Vasoactive intestinal peptide (VIP) and Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP), two neuromodulator peptides in the glucagon superfamily, have demonstrated positive regulation of osteoblast proliferation and activity. Using acidic oligopeptides, we have developed ligands that target to and accumulate at fracture sites. These targeting ligands can be synthesized in sequence with bone anabolic peptides to minimize off target effects and increase potency at the fracture site to create safer and ...
Aminoflavone Inhibits Α6-Integrin And Growth Of Tamoxifen Resistant Breast Cancer, 2018 Loma Linda University
Aminoflavone Inhibits Α6-Integrin And Growth Of Tamoxifen Resistant Breast Cancer, Petreena S. Campbell
Loma Linda University Electronic Theses, Dissertations & Projects
Approximately 40% of estrogen receptor positive (ER+) breast cancer patients develop resistance to standard of care agent tamoxifen, while ER negative (ER-) breast cancer patients are intrinsically resistant to tamoxifen. Resistance often promotes metastasis, recurrence and death. Tumor-initiating cells (TICs) represent key contributors to resistance and adhesion protein α6-integrin is a putative TIC biomarker. Investigational agent Aminoflavone (AF) demonstrates efficacy against breast cancer cells irrespective of ER status. Interestingly, we found tamoxifen resistant (TamR) cells and tumors exhibited elevated α6-integrin expression in comparison to their tamoxifen sensitive counterparts. AF effectively disrupted mammospheres enriched for TICs and reduced α6-integrin levels in ...

Altering the foreign body reaction by targeting macrophages has been of interest in the biomaterials field to improve the integration of longevity of implanted biomedical devices. The objective of this dissertation was to study the effect of locally delivered bioactive modulators on macrophage activation at the implantation site of different biomaterials in rats. Iloprost, a prostacyclin analog, was tested for its ability to direct macrophages to their pro-wound healing phenotype after the implantation of microdialysis probe in the subcutaneous space of male Sprague Dawley rats. This study showed that iloprost can shift macrophage activation states in vivo to the pro-wound ...
A V-To-F Substitution In Sk2 Channels Causes Ca2+ Hypersensitivity And Improves Locomotion In A C. Elegans Als Model, Young-Woo Nam, Sabia N. Baskoylu, Dimitris Gazgalis, Razan Orfali, Meng Cui, Anne C. Hart, Miao Zhang
Pharmacy Faculty Articles and Research
Small-conductance Ca2+-activated K+ (SK) channels mediate medium afterhyperpolarization in the neurons and play a key role in the regulation of neuronal excitability. SK channels are potential drug targets for ataxia and Amyotrophic Lateral Sclerosis (ALS). SK channels are activated exclusively by the Ca2+-bound calmodulin. Previously, we identified an intrinsically disordered fragment that is essential for the mechanical coupling between Ca2+/calmodulin binding and channel opening. Here, we report that substitution of a valine to phenylalanine (V407F) in the intrinsically disordered fragment caused a ~6 fold increase in the Ca2+ sensitivity of SK2-a channels. This substitution resulted in a ...

Pharmacy Faculty Articles and Research
Vancomycin has a complex pharmacokinetic profile and carries potential risks for nephrotoxicity and ototoxicity. The pharmacokinetic profile in elderly patients significantly differs from that of younger patients. It is common practice in many institutions for pharmacists to intentionally round serum creatinine levels to 1 mg/dl in elderly patients with levels <1 mg/ dl to avoid overestimating clearance and toxicities. This can potentially lead to underestimation of creatinine clearance, and subsequently lead to vancomycin under dosing. The aim of this study was to evaluate vancomycin target trough attainment and the time to trough attainment with vancomycin dosing per pharmacy in elderly patients.

Metformin Hydrochloride is an important pharmaceutical used for the treatment of type 2 diabetes. The current manufacturing of this product involves a well-known and proven process. The process includes the dissolution and reaction, followed by the precipitation of Metformin Hydrochloride. Although reliable and effective, the current process relies on the use of a solvent; which later needs to be eliminated from the precipitates. The purpose of this project is the investigation of an alternative reaction pathway which will avoid the use of solvents and simplify the final purification stage. The anticipated benefits include reduced costs for the processing and a ...
Site-Selective Modification Of Peptides And Proteins Via Organocatalyzed Henry Reaction, 2018 Seton Hall University
Site-Selective Modification Of Peptides And Proteins Via Organocatalyzed Henry Reaction, Zilma Pereira Muneeswaran
Seton Hall University Dissertations and Theses (ETDs)
In this research, peptides and protein containing serine on the N-terminus underwent site-selective modification following organocatalyzed bioconjugation that offered an additional functional group. It was shown that transforming the N-terminus serine to an aldehyde allowed site-specific bioconjugation to occur by utilizing the well-known Henry reaction. This method also grants a safer pathway for bioconjugation utilizing “green-chemistry” and biocompatible conditions. Amino acids and amino acid derived organocatalysts were utilized in the Henry reaction resulting in yields of up to 86 % conversion. Promising preliminary results were achieved in this research using peptides and myoglobin as the bioconjugation targets. Further investigation to be ...

Synthesis Of Novel 5-Substituted Pyrrolo[2,3-D]Pyrimidine Antifolates As Selective And Potent Anti-Tumor Agents, Mohammad Karim
Electronic Theses and Dissertations
In last few decades many folate analogs have been discovered and several compounds are successfully being used as anticancer agents. Methotrexate (MTX), pemetrexed (PMX), raltitrexed (RTX): are a few examples of classical antifolates that are currently in clinical use. Although these compounds are widely used, all of them show dose limiting toxicity due to their non-specific transport into normal cells as well as malignant cells. Currently, clinically used classical antifolates suffer from this disadvantage because there is no way to selectively transport them into malignant cells. Currently available antifolates are transported via reduced folate career (RFC) as well as Folate ...
Next Generation Of Translational Long-Acting Cabotegravir, 2018 University of Nebraska Medical Center
Next Generation Of Translational Long-Acting Cabotegravir, Tian Zhou
Theses & Dissertations
Recent development of long-acting antiretroviral therapeutic regimens has opened a new chapter for HIV/AIDS management. Cabotegravir (CAB), as one of the very first long-acting antiretroviral regimens, has drawn tremendous attention. However, the remaining challenges include suboptimal dosing intervals, large injection volume, injection site reactions, lack of tissue penetration, etc. As one of the pioneers in this field, our lab was successful in harnessing mononuclear phagocytes as “Trojan horses” for antiretroviral drug delivery and transportation to viral reservoirs. We proposed this targeted delivery strategy could address the limitations of current CAB formulation. To this end, we developed folic acid decorated ...
Novel Determinants That Influence Azole Susceptibility In Candida Glabrata And Candida Albicans, 2018 University of Tennessee Health Science Center
Novel Determinants That Influence Azole Susceptibility In Candida Glabrata And Candida Albicans, Sarah Garland Whaley
Theses and Dissertations (ETD)
Despite the scientific and medical communities’ best efforts, the incidence of fungal infections in susceptible populations continues to rise. The most common cause of these opportunistic fungal infections is Candida. In fact, Candida is the fourth most common pathogen associated with nosocomial blood stream infections. Reported mortality rates for patients with candidemia vary, but have not decreased in the past fifteen years and are reported to be as high as 50%. Candida glabrata, second only to Candida albicans among Candida infections, expresses high rates of resistance to treatment with arguably the best class of currently available antifungals - the azoles.
