The Complex Protein Analysis Of Purified Extracellular Vesicles In The Study Of Colorectal Cancer, Renee Boone, Cecilia Osthoff

Science University Research Symposium (SURS)

Proteomics, the study of complex protein mixtures in which liquid chromatography-mass spectrometry (LC-MS) is used to analyze peptide sequences, is commonly utilized to study the double membrane, cell-derived vesicles known as exosomes. Exosomes are double membrane, cell-derived vesicles that contain cell components such as DNA, lipids, and proteins. They function to transport proteins and cellular materials between cells and are involved in the progression and metastasis of cancer. The impact of these extracellular vesicles on cancer spread can be analyzed using proteomics, through the purification of the proteins isolated from the vesicles. The purpose of our research is to analyze …

Employing A Machine Learning Approach In Precision Oncology To Predict Pik3ca Functional Status And Identify Phenocopying Variants Of Deleterious Pik3ca Mutations, Javier Castillo

CMC Senior Theses

The following proposal describes a modular machine learning approach that detects malfunctioning genes and pathways in cancer using the transcriptome of cancer patients. The transcriptome is underused in precision oncology and, combined with machine learning, can aid in the identification of hidden responders. Applied to the PI3K/AKT/mTOR pathway, this method can be used to predict PIK3CA functional status and identify phenocopying variants of deleterious PIK3CA mutations. The classifier will do this by integrating RNA-seq, copy number, and mutation data from tumors to determine the functional status of PIK3CA using a set of learned gene-specific weights. The classifier will then be …

Inhibiting Pi3k/Akt To Enhance Brain Uptake Of Anticancer Agents In Glioblastoma, Louis Rodgers

Theses and Dissertations--Pharmacy

Glioblastoma (GBM) is the deadliest and most common malignant CNS tumor. Despite advances in understanding its biology and the development of targeted therapies, effective treatment options remain limited. As a result, patient survival rates are dismal, with a 5-year survival rate of only 6.8% and an overall survival of less than two years. This poor outcome is partly due to our inability to treat GBM cells that infiltrate the whole brain. Focal treatments like surgery and radiotherapy alone are insufficient due to these invasive tumor cells. Therefore, chemotherapy following resection and irradiation of the primary tumor is essential to eliminate …

Compton Scattering Of Mammographic Soft X-Ray Beams By Alkali And Transition Metal Salt Filters Produce X-Ray Interference Zones That May Have Treatment Potential For Localized Cancer Lesions, Subhendra N. Sarkar, Eric Lobel, Sabina Rakhmatova, Derbie Desir, Somdat Kissoon, Daler Djuraev, Katie Tam

Publications and Research

In breast x-ray imaging scattered radiation adds 50% of harmful radiation dose from anisotropic Compton scattering mechanism. We have been working with double layered inorganic salt materials that can induce Compton scattering to the incident mammographic x ray beams (in 20-30 kVp range) with adequate isotropy (angular control). Typically metal nitrates and alkali halide salt layers are shown here to cause low energy radiation interference zones with high and low photon intensities and local flux heterogeneity in terms of flux covariance. Spatial variation of low energy photon flux creates concentrated and sparse radiation zones that may be used to induce …

Androgen Receptor: A Complex Therapeutic Target In Breast Cancer, Sarah Tinuade Asemota

Theses and Dissertations (ETD)

Breast cancer is classified based on the expression of three markers estrogen receptor (ER), progesterone receptor, and human epidermal growth factor receptor (HER2). Breast cancers that express these targets are classified as hormone receptor (HR) positive breast cancer and the tumors that lack the expression of these markers are classified as triple negative breast cancer (TNBC). Though HR-positive breast cancer is treated with hormonal and cyclin-dependent kinase 4/6 targeted therapies, the cancer relapses and becomes resistant to the treatment options. Androgen receptor (AR) that is expressed in over 90\% of ER-positive breast cancer and in 20\% of TNBC is a …

Pca-Clf: A Classifier Of Prostate Cancer Patients Into Patients With Indolent And Aggressive Tumors Using Machine Learning, Yashwanth Karthik Kumar Mamidi, Tarun Karthik Kumar Mamidi, Md Wasi Ul Kabir, Jiande Wu, Md Tamjidul Hoque, Chindo Hicks

School of Medicine Faculty Publications

A critical unmet medical need in prostate cancer (PCa) clinical management centers around distinguishing indolent from aggressive tumors. Traditionally, Gleason grading has been utilized for this purpose. However, tumor classification using Gleason Grade 7 is often ambiguous, as the clinical behavior of these tumors follows a variable clinical course. This study aimed to investigate the application of machine learning techniques (ML) to classify patients into indolent and aggressive PCas. We used gene expression data from The Cancer Genome Atlas and compared gene expression levels between indolent and aggressive tumors to identify features for developing and validating a range of ML …

Breast cancer (BC) is the second most fatal disease and is the prime cause of cancer allied female deaths. BC is caused by aberrant tumor suppressor genes and oncogenes regulated by transcription factors (TFs) like NF-κB. NF-κB is a pro-inflammatory TF that crucially alters the expressions of various genes associated with inflammation, cell progression, metastasis, and apoptosis and modulates a network of genes that underlie tumorigenesis. Herein, we focus on NF-κB signaling pathways, its regulators, and the rationale for targeting NF-κB. This review also includes TFs that maintain NF-κB crosstalk and their roles in promoting angiogenesis and metastasis. In addition, …

Fluoropyridine-based chemotherapy remains the most widely used treatment for colorectal cancer (CRC). In this study, we investigated the mechanism by which the natural product Scutellaria baicalensis (Huang Qin; HQ) and one of its main components baicalin enhanced 5-fluorouracil (5-FU) antitumor activity against CRC. Cell proliferation assays, cell cycle analysis, reverse-phase protein array (RPPA) analysis, immunoblot analysis, and qRT-PCR were performed to investigate the mechanism(s) of action of HQ and its active components on growth of CRC cells. HQ exhibited in vitro antiproliferative activity against drug resistant human CRC cells, against human and mouse CRC cells with different genetic backgrounds and …

Barriers To Colorectal Cancer Screening For Low-Income Hispanic Men In Urban Areas Between 50-75, Alex Vega

Rowan-Virtua Research Day

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. Although CRC screening rates have improved in non-Hispanic whites (NHW), Hispanic adult males (HAM) aged 50-75 in urban areas continue to experience low screening rates and higher CRC morbidity and mortality. This review aims to identify the barriers to CRC screening among HAM and propose targeted interventions to increase screening rates. A comprehensive literature review was conducted using databases such as PubMed, Scopus, and Google Scholar. Key search terms included "colorectal cancer", "screening", "Hispanic adult males", "urban", "barriers", and "interventions". Factors identified include poverty, language …

Cellular Metabolism Therapy Slowing Growth Rate Of Glioblastomas, Heet Patel

Rowan-Virtua Research Day

Glioblastoma Multiforme (GBM), more commonly known as glioblastomas, are a form of specialized brain tumors called gliomas. Glioblastomas most commonly occur in glial cells of the central nervous system and the average age of diagnosis is 64. Treatment methods implemented currently are surgery of the removable masses followed by courses of chemotherapy and radiotherapy. These methods can only prolong the life span by a few months and as such, new research focused on tumor cell metabolism is being conducted to determine its impact on the progression of this tumor. Tumor masses, such as Glioblastomas, modify their metabolism via the Warburg …

Tcf4 Is A Key Mediator Of Cell Identity And Oncogenesis In Neuroblastoma, Nour Aljouda

Theses and Dissertations (ETD)

Neuroblastomas (NB) are embryonal childhood tumors that derive from the multipotent neural crest cells (NCCs) of the peripheral nervous system. NB accounts for more than 15% of all childhood cancer-related deaths. Despite the most intensive multimodal therapy, more than 50% of patients with high-risk NB relapse with often fatal, resistant disease. Novel therapies are desperately needed to improve cure rates. Previous studies proposed that the deregulation of normal neural crest developmental programs contributes to NB oncogenesis by retaining the highly migratory and proliferative traits of NCCs. Thus, activation or repression of neural crest developmental pathways have been implicated in NB …

Inhibition Of Kdm4 With Qc6352 To Target High-Risk Neuroblastoma, Ahmed M. Abuzaid

Theses and Dissertations (ETD)

Neuroblastoma (NB) is a malignancy of improperly maturated nerve tissues of the sympathetic nervous system. It is the most diagnosed extracranial solid tumor of childhood, and it accounts for roughly up to 10% of all childhood malignancies and 15% of all childhood malignancy-related deaths. MYCN amplification, occurring in 20-25% of all NB patients and 50% of all high-risk NB patients, is the well-characterized genetic abnormality and is associated with ill-fated outcomes. Regrettably, in spite of the contemporary therapeutic advances and aggressive combinatorial treatments, the overall 5-year event-free survival rate is roughly 51% with a 5-year overall survival rate of nearly …

Outpatient Breast Cancer Screening Documentation, Christoffer A. Amdahl, Jeremy Smith

North Texas GME Research Forum 2023

Introduction: Over 264,000 cases of breast cancer are diagnosed annually within the United States, with 99% of them being in women. Regarding prevention of this terrible disease, early detection of such cancers through screening mammography has up to a 20% reduction in breast cancer mortality. Therefore, the USPSTF recommends screening of women who are 50-74 years of age via mammography at average risk of breast cancer every two years. The goal of this study was to measure, track, and increase compliance with these screening recommendations within the Medical City resident clinics.

Method: Family medicine residents working were presented with a …

Ido1 And Inflammatory Neovascularization: Bringing New Blood To Tumor-Promoting Inflammation, Alexander J. Muller, Arpita Mondal, Souvik Dey, George C Prendergast

Kimmel Cancer Center Faculty Papers

In parallel with the genetic and epigenetic changes that accumulate in tumor cells, chronic tumor-promoting inflammation establishes a local microenvironment that fosters the development of malignancy. While knowledge of the specific factors that distinguish tumor-promoting from non-tumor-promoting inflammation remains inchoate, nevertheless, as highlighted in this series on the 'Hallmarks of Cancer', it is clear that tumor-promoting inflammation is essential to neoplasia and metastatic progression making identification of specific factors critical. Studies of immunometabolism and inflamometabolism have revealed a role for the tryptophan catabolizing enzyme IDO1 as a core element in tumor-promoting inflammation. At one level, IDO1 expression promotes immune tolerance …
