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

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 …

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 …

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 …

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. …
