Role Of Human Intermediate Form Prl Receptor I-Tail In The Pathogenesis Of Breast Cancer, Shanwei Shen

Theses and Dissertations

Breast cancer continues to be the second most common cancer in women in the United States. The neuroendocrine hormone human prolactin (hPRL) plays an important role in normal mammary gland development and growth, stimulating normal breast tissue proliferation and differentiation. Considerable evidence has shown that hPRL is involved in the malignant transformation of human breast tissue. hPRL enhances viability, invasiveness, and proliferation of breast cancer cells in vitro. Evidence from epidemiologic and genetic studies also implicates role of hPRL in the pathogenesis of breast cancer. Its cognate receptor the human prolactin receptor (hPRLr) is required for the action of hPRL. …

Pan-Cancer Genomic Characterization Of Human Papillomavirus Associated Tumors, Jeremiah Ray Holt

Theses and Dissertations (ETD)

Infection with high-risk human papillomavirus (HPV) accounts for nearly all cervical cancers (CESC), a subset of other anogenital squamous cancers, and increasing rates of head and neck squamous cell carcinomas (HNSC), with each cancer type having heterogenous outcomes due to a general lack of personalized care. Large scale genomic analyses have catalogued the somatic alterations occurring frequently among squamous tumor types including HNSC and CESC, but few studies have incorporated a thorough analysis of HPV genomics. High-risk HPVs are double-stranded DNA (dsDNA) viruses capable of integrating their genomes into host chromosomes, a phenomenon known to promote HPV-associated cancer formation. HPV …

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 …

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 …

BACKGROUND: Neck dissections (ND) are a routine procedure in head and neck oncology. Given the postoperative functional impact that some patients experience, it is imperative to identify and track quality of life (QoL) symptomatology to tailor each patient's therapeutic needs. To date, there is no validated French-Canadian questionnaire for this patient-population. We therefore sought to translate and validate the Neck Dissection Impairment Index (NDII) in Canadian French.

METHODS: A 3-phased approach was used. Phase 1: The NDII was translated from English to Canadian French using a "forward and backward" translational technique following international guidelines. Phase 2: A cognitive debriefing session …

Faculty, Staff and Students Publications

There is a paucity of literature on the effect of COVID-19 on hospital processes. We hypothesized that COVID-19 was associated with decreased cancer physiatry referrals in 2020. This is a retrospective cohort study of consecutive patients from April to July 2019 and 2020 admitted at an academic quaternary cancer center. The main outcomes were number of hospital admissions, rate, and characteristics of inpatient rehabilitation admissions and change in percentage of physiatry referrals as the primary endpoint. Results showed that in 2019, there were 387 referrals from 10,274 inpatient admissions (3.8%; 95% confidence interval, 2.4-4.2), compared with 337 referrals from 7051 …

Steroid Receptor Coactivators In Treg And Th17 Cell Biology And Function, Yosi Gilad, Ortal Shimon, Sang Jun Han, David M Lonard, Bert W O'Malley

Faculty, Staff and Students Publications

Steroid receptor coactivators (SRCs) are master regulators of transcription that play key roles in human physiology and pathology. SRCs are particularly important for the regulation of the immune system with major roles in lymphocyte fate determination and function, macrophage activity, regulation of nuclear factor κB (NF-κB) transcriptional activity and other immune system biology. The three members of the p160 SRC family comprise a network of immune-regulatory proteins that can function independently or act in synergy with each other, and compensate for - or moderate - the activity of other SRCs. Recent evidence indicates that the SRCs are key participants in …

Translational Approaches To Address The Metastatic/Resistant (Mr) Phenotype Of Non-Small Cell Lung Cancer Brain Metastases, Kent L. Marshall

Graduate Theses, Dissertations, and Problem Reports (ETD)

Lung cancer remains the most frequently diagnosed malignant neoplasm shared in men and women worldwide, second only to the sexually dimorphic prostate cancer in men and breast cancer in women. Overall, lung cancer was responsible for 12.5% of new cancer cases globally in the year 2022. Of these cases, 80-85% are non-small cell lung cancer (NSCLC), a highly genotypically diverse sub-type of lung cancer. Over the past three decades, extraordinary improvement in screening, smoking cessation, early diagnosis and targeted therapy have been made, improving NSCLC survival markedly. However, as patients are surviving their primary disease better, there is a temporal …
