Targeting Oncogenic Gαq/11 In Uveal Melanoma, Dominic Lapadula, Jeffrey L Benovic

Department of Biochemistry and Molecular Biology Faculty Papers

Uveal melanoma is the most common intraocular cancer in adults and arises from the transformation of melanocytes in the uveal tract. While treatment of the primary tumor is often effective, 36–50% of patients develop metastatic disease primarily to the liver. While various strategies have been used to treat the metastatic disease, there remain no effective treatments that improve survival. Significant insight has been gained into the pathways that are altered in uveal melanoma, with mutually exclusive activating mutations in the GNAQ and GNA11 genes being found in over 90% of patients. These genes encode the alpha subunits of the hetetrotrimeric …

Differentiating The Mechanistic Role And Chemotherapeutic Potential Of Src And Podoplanin In Oncogenic Transformation, Edward P. Retzbach

Graduate School of Biomedical Sciences Theses and Dissertations

There were an estimated 20 million new cancer cases worldwide in 2020, resulting in nearly 1000 deaths per hour [1]. Oral cancer exemplifies the difficulties of treating cancer patients. The first line for oral cancer treatment is surgery and radiation that can lead to patient disfigurement and decreased quality of life in cancer survivors [2-4]. Though there have been many developments in chemotherapy in the last 30 years, the 50% mortality rate associated with oral cancer has not changed [4, 5]. Longitudinal studies that track survival rates in oral cancer patients demonstrate a 3-fold reduction in patient deaths when patients …

The Role Of Ifitm3 In The Immune Response Of Brca-Deficient High Grade Serous Ovarian Carcinoma, Han Cun

Dissertations & Theses (Open Access)

Background: Prior studies showed that BRCA-deficient high grade serous ovarian carcinoma (HGSOC) had increased tumor infiltrating lymphocytes (TILs) compared to BRCA-wildtype (WT). To better understand the underlying immune mechanism in these tumors, a preliminary transcriptome analysis was performed on a set of microdissected HGSOC tumor specimens with BRCA1-mutation, BRCA2-mutation, or WT. This demonstrated an upregulation of IFITM3, an essential gene in modulating immune function. Based on these findings, we hypothesized that BRCA-deficient HGSOC have increased DNA damage leading to upregulation of IFITM3 and subsequent increase in antigen presentation and T-cell activation.

Methods: Following IRB approval, preliminary transcriptome analysis was performed …

The Current Landscape Of Antibody-Based Therapies In Solid Malignancies, Ashu Shah, Sanchita Rauth, Abhijit Aithal, Sukhwinder Kaur, Koelina Ganguly, Catherine Orzechowski, Grish C. Varshney, Maneesh Jain, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

Over the past three decades, monoclonal antibodies (mAbs) have revolutionized the landscape of cancer therapy. Still, this benefit remains restricted to a small proportion of patients due to moderate response rates and resistance emergence. The field has started to embrace better mAb-based formats with advancements in molecular and protein engineering technologies. The development of a therapeutic mAb with long-lasting clinical impact demands a prodigious understanding of target antigen, effective mechanism of action, gene engineering technologies, complex interplay between tumor and host immune system, and biomarkers for prediction of clinical response. This review discusses the various approaches used by mAbs for …
