In Vivo Analysis Of A Salt Bridge At The External Gate Of The Drosophila Melanogaster Serotonin Transporter In Response To Amphetamines, Timothy J. Beenen

Open Access Theses

Monoamine neurotransmitter transporters are membrane proteins responsible for the clearing of biogenic amines from a synapse. These transporters are targets for many important pharmaceuticals including antidepressants, as well as psychostimulant drugs such as cocaine and amphetamines. Amphetamines are believed to elicit their psychostimulant activity primarily by inducing a reversal of the transport cycle and increasing neurotransmitter release into the synapse, though the mechanism of this activity is incompletely understood. Previous in vitro research has suggested functional significance of a conserved salt bridge in the serotonin transporter (SERT) in amphetamine-induced 5-HT efflux. This salt bridge is disrupted in the Drosophila melanogaster …

The Therapeutic Targeting Of Folate Receptor Alpha Positive Tumors Via Folate Receptor Selective Novel 5- And 6- Substituted Pyrrolo [2,3-D]Pyrimidine Antifolates", Shermaine Kimberly Mitchell-Ryan

Wayne State University Dissertations

Ovarian Cancer is the fifth leading cause of cancer-related death of women in the United States. Epithelial Ovarian Cancer (EOC) constitutes 85-90% of malignancies within the ovary, with an alarming majority of these cases diagnosed at advanced stage. While most patients are initially highly responsive to the current treatment standard, there is a very high probability that they will recur with a drug resistant fatal disease. Currently there is no validated comprehensive model of disease progression for ovarian cancer, although tremendous progress has been made in understanding the origin of this disease and a putative precursor lesion has been identified …

Photodynamic Therapy As An Effective Therapeutic Approach In Mame Models Of Triple Negative And Inflammatory Breast Cancers, Neha Aggarwal

Wayne State University Dissertations

Introduction: Photodynamic therapy (PDT) is a minimally invasive, FDA approved therapy for

treatment of several indications including endobronchial and esophageal cancers that are

accessible to light. Triple negative breast cancer (TNBC) and inflammatory breast cancer (IBC)

are aggressive and lethal subtypes of breast cancer that spread to chest wall and dermal

lymphatics, respectively, sites that would be accessible to light. Both TNBC and IBC patients

have a relatively poor survival rate due to lack of targeted therapies. Use of PDT is

underexplored for breast cancers but has been proposed for treatment of subtypes for which a

targeted therapy is unavailable. …

Proteasome Inhibition As A Potential Anti-Breast Cancer Therapy: Mechanisms Of Action And Resistance-Reversing Strategies, Rahul Rajesinh Deshmukh

Wayne State University Dissertations

AMPK activation and Ubiquitin Proteasome System (UPS) inhibition have gained great attention as therapeutic strategies for the treatment of certain types of cancers. While AMPK serves as a master regulator of cellular metabolism, UPS regulates protein homeostasis. Although the crosstalk between them is suggested, the relationship between these two important pathways is not very clear. We observed that proteasome inhibition leads to AMPK activation in human breast cancer cells. We report that a variety of proteasome inhibitors activate AMPK in all of the tested cancer cell lines. Our data using Liver Kinase B1 (LKB1)-deficient cancer cells suggests that proteasome inhibitor-induced …

Novel Protein Phosphatase 2a Complexes In Skeletal Muscle From Obese Insulin Resistant Human Participants, Divyasri Damacharla

Wayne State University Theses

Type 2 Diabetes is a metabolic disorder associated with insulin resistance and consequent high blood glucose levels. Maximum glucose disposal takes place in skeletal muscle and studying skeletal muscle insulin resistance is crucial. Protein Phosphatase 2A (PP2A) is one of the major serine/threonine phosphatases belonging to PhosphoProteinPhosphatase (PPP) family. It constitutes about 80% of all serine/threonine phosphatases. It is regulated by numerous regulatory subunits as well as other substrate molecules and post translational modifications. This alters their localization, activity and also its target molecules. Many evidences show the effect of insulin on PP2Ac and its abnormal regulation in conditions of …

The Role Of E3 Ligase Parkin In Trafficking Of Monoamine Storage Vesicles In Rat Model Of Methamphetamine Neurotoxicity, Heli Dineshchandra Chauhan

Wayne State University Theses

Methamphetamine (METH), a psychostimulant, is a widely used drug of abuse. METH is toxic to dopaminergic (DAergic) and serotonergic (5-HT) nerve terminals in the striatum when administered at high doses. METH releases Dopamine (DA) from vesicular monoamine transporter 2 (VMAT2) containing synaptic vesicles and induces oxidative stress by auto-oxidation of DA. The VMAT2 plays a neurprotective role by sequestering cytoplasmic DA into vesicles for storage and protection from auto-oxidation. It has previously been shown that METH toxicity is associated with impaired VMAT2 trafficking and oxidative damage to the E3 ligase parkin. CDCrel1, a protein found to inhibit exocytosis, is regulated …

Effect Of Metformin On Global Phosphorylation Profiles Of Primary Skeletal Muscle Cells Derived From Overweight/Obese Insulin Resistant Human Participants, Nishit Shah

Wayne State University Theses

Metformin is a drug from the biguanide class and it has been in use for the treatment of type 2 diabetes for a long time, and it can improve insulin sensitivity in skeletal muscle. However, the mechanism for metformin’s action is unclear. Phosphatases and kinases, and their subunits are the proteins required for dephosphorylation and phosphorylation of proteins in cells during various signaling pathways. Phosphorylation studies of proteins from primary cell culture derived from skeletal muscle tissue from obese/overweight insulin resistant participants will help to understand the regulation of phosphorylation in phosphatases and kinases by metformin.

In the current research, …

Therapeutic Targeting Of Bmp2 In Nf1-Deficient Malignant Peripheral Nerve Sheath Tumors (Mpnsts), Sidra Ahsan

Wayne State University Dissertations

Neurofibromatosis type I (NF1)-deficient malignant peripheral nerve sheath tumor (MPNST) is an aggressive tumor for which the standard treatment is surgical removal with wide margins, often leaving behind cancer cells needing chemotherapy. RAS-GRD is the most widely studied functional target of NF1 implicated in tumorigenesis, however, therapeutic interventions targeting RAS activity have met with limited success. Using gene expression profiling, our lab identified BMP2-SMAD1/5/8 signaling pathway as a therapeutic target in MPNSTs, independent of the NRAS and MEK1/2 regulation. The overall goal of my research was to validate the significance of BMP2 in MPNSTs in novel cellular models, study the …

Cross-Talk Between The Tumor Suppressors Par-4 And P53, Tripti Shrestha Bhattarai

Theses and Dissertations--Toxicology and Cancer Biology

This work describes the fascinating interplay between two tumor suppressors Prostate apoptosis response-4 (Par-4) and p53. The guardian of the genome, p53, is frequently mutated in human cancers, and may contribute to therapeutic resistance. However, p53 is intact and functional in normal tissues, and we observed that specific activation of p53 in normal fibroblasts could induce apoptosis selectively in p53-deficient cancer cells. This paracrine apoptotic effect was executed by Par-4 secreted in response to p53 activation. Accordingly, activation of p53 in wild-type mice, but not in p53^-/- or Par-4^-/- mice, caused systemic elevation of Par-4 that induced apoptosis …

Elaboration And Design Of Α7 Nachr Negative Allosteric Modulators, Osama I. Alwassil

Theses and Dissertations

α7 Neuronal nicotinic acetylcholine receptors are one of two major classes of receptors responsible for cholinergic neurotransmission in the central nervous system. The existence of α7 neuronal nAChRs in different regions of the nervous system suggests their involvement in certain essential physiological functions as well as in disorders such as Alzheimer’s disease (AD), drug dependence, and depression. This project was aimed toward the discovery and development of small–molecule arylguanidines that modulate α7 nAChR function with improved subtype-selectivity through an allosteric approach. Identifying the required structural features of these small molecules allowed optimization of their negative allosteric modulator (NAM) actions at …

Pemetrexed, A Modulator Of Amp-Activated Kinase Signaling And An Inhibitor Of Wild Type And Mutant P53, Stuti Agarwal

Theses and Dissertations

New drug discoveries and new approaches towards diagnosis and treatment have improved cancer therapeutics remarkably. One of the most influential and effective discoveries in the field of cancer therapeutics was antimetabolites, such as the antifolates. The interest in antifolates increased as some of the antifolates showed responses in cancers, such as mesothelioma, leukemia, and breast cancers. When pemetrexed (PTX) was discovered, our laboratory had established that the primary mechanism of action of pemetrexed is to inhibit thymidylate 22 synthase (TS) (E. Taylor et al., 1992). Preclinical studies have shown that PTX has a broad range of antitumor activity in human …

Integrated Nanoscale Imaging And Spatial Recognition Of Biomolecules On Surfaces, Congzhou Wang

Theses and Dissertations

Biomolecules on cell surfaces play critical roles in diverse biological and physiological processes. However, conventional bulk scale techniques are unable to clarify the density and distribution of specific biomolecules in situ on single, living cell surfaces at the micro or nanoscale. In this work, a single cell analysis technique based on Atomic Force Microscopy (AFM) is developed to spatially identify biomolecules and characterize nanomechanical properties on single cell surfaces. The unique advantage of these AFM-based techniques lies in the ability to operate in situ (in a non-destructive fashion) and in real time, under physiological conditions or controlled micro-environments.

First, AFM-based …
