Association Between Education And Allostatic Load With Risk Of Cancer Mortality Among Hispanic Women, Melissa Lopez-Pentecost, Cynthia Li, Marlo Vernon, Sydney P. Howard, Jessica Amezcua, Justin Xavier Moore

Markey Cancer Center Faculty Publications

Purpose: Cancer remains the leading cause of death among Hispanics in the US. While social determinants of health, such as educational attainment, have been linked to negative health outcomes, their biological mechanisms remain poorly understood. We evaluated the association between educational attainment and allostatic load (AL), a measure of chronic physiologic stress, with risk of cancer mortality in Hispanic women from the National Health and Nutrition Examination Survey (NHANES).

Methods: We performed a retrospective analysis among 5637 Hispanic women in NHANES from 1988 to 2010 with follow-up data through 2019. Educational attainment was categorized into a two-level variable: less than …

Functional Assessment Of Migration And Adhesion To Quantify Cancer Cell Aggression, Lauren E. Mehanna, James D. Boyd, Chloe G. Walker, Adrianna R. Osborne, Martha E. Grady, Brad J. Berron

Markey Cancer Center Faculty Publications

During epithelial-to-mesenchymal transition (EMT), cancer cells lose their cell–cell adhesion junctions as they become more metastatic, altering cell motility and focal adhesion disassembly associated with increased detachment from the primary tumor and a migratory response into nearby tissue and vasculature. Current in vitro strategies characterizing a cell’s metastatic potential heavily favor quantifying the presence of cell adhesion biomarkers through biochemical analysis; however, mechanical cues such as adhesion and motility directly relate to cell metastatic potential without needing to first identify a cell specific biomarker for a particular type of cancer. This paper presents a comprehensive comparison of two functional metrics …

Inclusion Of Surgery In Multimodality Treatment Is Predictive Of Better Survival In Stage Iiia Non-Small Cell Lung Cancer: An Inverse Probability Treatment-Weighting Analysis, Feitong Lei, Janeesh Sekkath-Veedu, Bin Huang, Quan Chen, Mansi Shah-Jadeja, Thomas E. Stinchcombe, Zhonglin Hao

Markey Cancer Center Faculty Publications

Introduction: Stage IIIA non-small cell lung cancers (NSCLC) are treated with surgery-based multimodality approach or definitive chemoradiation therapy plus durvalumab consolidation. It is not clear whether surgery-based multimodality therapy has any survival advantage over definitive chemoradiation plus immunotherapy consolidation.

Method: National Cancer Database (NCDB) was used to identify NSCLC patients at stage IIIA (AJCC8, T3N1/T4N0-1 or T1N2/T2N2) who are treated with surgery-based multimodality approach or definitive chemoradiation plus durvalumab. Survival between groups were compared using inverse probability treatment weighting (IPTW)-adjusted Kaplan Meier curves and Cox proportional hazards regression analysis. Results were independently confirmed by Landmark Inverse and Clone Censor Weight …

Background: Ovarian cancer typically presents at an advanced stage, has a poor prognosis, and is a leading cause of cancer-related deaths in women. Extracellular vesicles (EVs) are cell membrane-derived nanoparticles that function in specific cell- to-cell communication and are under development as novel drug delivery vehicles and modulators of the tumor microenvironment. Artificial cell-derived vesicles (ACDVs) from M1 macrophages are able to repolarize macrophages from a M2 to a M1 phenotype and target tumor cells in in vitro studies.

Results: In this study, we generated engineered EVs (EEVs) by membrane disruption of M1 macrophages (MEVs) with and without cisplatin to …

Markey Cancer Center Faculty Publications

The National Cancer Institute’s (NCI) Cancer Center Support Grant mandates that NCI-designated cancer centers establish a Community Outreach and Engagement (COE) component to help direct efforts at reducing cancer burden within their catchment areas. Despite the critical role of COE offices, little is known about how they track and evaluate outreach activities and outcomes. We gathered information on current practices from representatives of 40 out of 65 COE offices using an online survey. Although nearly all responding centers (97.5%) tracked COE activities, no consensus existed on resources used, and satisfaction with current solutions was mixed (51.0% not satisfied). Respondents expressed …

Many eukaryotic species undergo programmed elimination of specific chromosomes during embryogenesis, typically retaining these chromosomes only in their germ cells. In some species, programmatic elimination of GRCs, or sex chromosomes, also occurs in a sex-specific manner, with specific chromosomes being transmitted or eliminated by only one sex. As such, these chromosomes provide a unique perspective on the evolution of gene functions that are advantageous to the germline and genetic tradeoffs between somatic vs germline or oocyte vs sperm biology. While GRCs have been extensively characterized in male sea lampreys (Petromyzon marinus), the status of GRCs in females has not yet …

Markey Cancer Center Faculty Publications

BCR::ABL1-like B-lymphoblastic leukaemia (B-ALL) neoplasms lack the BCR::ABL1 translocation but have a gene expression profile like BCR::ABL1 positive B-ALL. This includes alterations in cytokine receptors and signalling genes, such as CRLF2, ABL1, ABL2, JAK2, PDGFRB and EPOR. Cases with CRLF2 rearrangements account for approximately 50% of cases of Philadelphia-like acute lymphoblastic leukaemia (Ph-like ALL), and the frequency of specific genomic lesions varies with ethnicity such that IGH::CRLF2 translocations are more common in Hispanics and Native Americans. We report two cases of BCR::ABL1-like ALL, with significant eosinophilia. A Hispanic man in his early 20s and a Hispanic woman in her 50s …

Inactivation of p53 by mutations commonly occurs in human cancer. The mutated p53 proteins may escape proteolytic degradation and exhibit high expression in tumors and acquire gain-of-function activity that promotes tumor progression and chemo-resistance. Therefore, selectively targeting of the gain-of-function p53 mutants may serve as a promising therapeutic strategy for cancer prevention and treatment. In this study, we identified cabozantinib, a multikinase inhibitor currently used in the clinical treatment of several types of cancer, as a selective inducer of proteasomal degradation of the p53-Y220C mutant. We demonstrate that cabozantinib disrupts the interaction between p53Y220C and USP7, a deubiquitylating enzyme, resulting …

A High-Throughput Workflow For Assessing Self-Renewal Using Colony Formation Assays, Majd Al-Hamaly, Jessica S. Blackburn Jan 2025

A High-Throughput Workflow For Assessing Self-Renewal Using Colony Formation Assays, Majd Al-Hamaly, Jessica S. Blackburn

Markey Cancer Center Faculty Publications

The colony formation assay (CFA) is a widely used method to assess the self-renewal capacity of cancer cells and evaluate how this property is affected by drug treatment. This protocol presents a streamlined, high-throughput CFA workflow optimized for T-cell acute lymphoblastic leukemia (T-ALL), making it suitable for large-scale drug screening projects. Colonies are grown in a methylcellulose-based 3D matrix and quantified using an automated analysis pipeline, allowing robust estimation of colony number and size. This cost-effective approach provides a scalable platform for identifying compounds that impair self-renewal, facilitating prioritization of hits for validation in more complex in vivo models.

Markey Cancer Center Faculty Publications

We identified a germline TP53 c.758C > T (p.T253I) mutation in the TP53 tumor suppressor gene in a pediatric adrenocortical carcinoma (ACC) patient. Characteristic of pathogenic p53 mutations, we observed upregulation of total p53 protein levels in the patient’s ACC and concurrent suppression of the wild-type (WT) TP53 allele. As ACC can be associated with Li-Fraumeni Syndrome (LFS) and the mutation has not yet been linked to LFS, we sought to characterize the functionality of the T253I mutation. We acquired p53-/-HEK293 cells and stably transduced them with GFP-tagged wild type (T253) or T253I p53 as well as two established …

Cisplatin-Loaded M1 Macrophage-Derived Vesicles Have Anti-Cancer Activity In Osteosarcoma, Namrata Anand, Joseph Robert Mccorkle, David Schweer, Lan Li, Kristen S. Hill, Melissa A. Fath, Derek B. Allison, Christopher L. Richards, Jill M. Kolesar

Markey Cancer Center Faculty Publications

Osteosarcoma (OS) is a relatively rare bone malignancy that primarily affects children and young adults and is associated with significant morbidity and mortality. Cisplatin is a mainstay of treatment, but its efficacy is limited by off-target toxicities. Immunotherapy is not effective due to a poor antigenic tumor microenvironment. Here, we address these challenges by using manufactured M1 macrophage-derived vesicles (MVs) loaded with cisplatin. Human blood and mouse RAW 264.7 M1 macrophages were used to prepare empty (E-MVs) and cisplatin-loaded MVs (C-MVs). Human OS cell lines were used in vitro and in a tibia xenograft mouse model to evaluate the anti-cancer …

Racial differences in health care access (HCA) may contribute to disparities in ovarian cancer (OC) survival. We used structural equation models (SEMs) to examine associations between race and HCA domains (affordability, availability, accessibility) in relation to overall and OC-specific mortality. Non-Hispanic (NH)–Black and non-Black (Hispanic, NH-White) women diagnosed with OC in 2008-2015 were identified from Surveillance, Epidemiology, and End Results–Medicare. Cox proportional hazards regression was used to conduct mediation analysis for associations between race and HCA domains with overall and OC-specific mortality. SEM models adjusting for demographic and clinical covariates were used to estimate hazard ratios (HRs) and 95% CIs. …

Cancer-Associated Fibroblast Secreted Dkk1 Promotes The Immunosuppressive Tumor Microenvironment And Colorectal Cancer Resistance To Chemotherapy, Zhijie Yin, Yuning Zhou, Xudong Zhu, Ryan A. Goettl, Chi Wang, Heidi L. Weiss, B. Mark Evers, Qingding Wang

Markey Cancer Center Faculty Publications

Chemotherapy is the cornerstone of treatment for colorectal cancer (CRC). However, acquired resistance can lead to a decrease in the efficiency of chemotherapy. Here, we show that cancer-associated fibroblasts (CAFs) play a critical role in acquired resistance to chemotherapy. Treatment with 5-fluorouracil (5-FU), oxaliplatin, or SN38 (an active metabolite of irinotecan) increased DKK1 expression and secretion, activation of MEK/ERK, and upregulation of p53 in CAFs. Knockdown of p53 or inhibition of MEK/ERK blocked the increase in DKK1 expression induced by chemotherapeutic agents in CAFs. Consistently, elevated DKK1 and phospho-ERK levels were found in CAFs isolated from surgically resected samples of …

Markey Cancer Center Faculty Publications

Fibrosis is an important feature of adipose tissue in obese individuals; nevertheless, roles of obesity-associated extracellular matrix (ECM) deposition in breast cancer progression largely remain elusive. Here, we show that expression of Hsp47, a chaperone protein involving collagen secretion, is induced in adipose tissue from obese humans and mice. Adipocyte-specific Hsp47 deletion (Adi-KO) suppresses the high-fat diet (HFD)-induced obesity and mammary tumor progression, accompanied by a reduction in ECM deposition. Matrisome analyses lead to the identification of asporin as a new target of Hsp47 in adipose tissue. Co-immunoprecipitation results confirm that the recruitment of Hsp47 enhances asporin secretion in adipocytes. …

Markey Cancer Center Faculty Publications

Purpose: Despite high rates of lung disease and lung cancer among women, few studies have focused on adverse lung health risk factors among rural Appalachian women. We aim to describe the prevalence of demographic, behavioral, and economic characteristics among a cohort of rural Appalachian women and ascertain the association between these risk factors and lung function.

Methods: Through a cross-sectional study in two rural Appalachian Kentucky counties (2015–2017), we collected demographics, health history/behaviors, and lung function via pulmonary function tests. Restricting to female participants with interpretable pulmonary function tests (N = 456), we estimated prevalence ratios of the association …


The Implementation Of The Queensland Health Smoking Cessation Clinical Pathway In A Western Australian Private Hospital Setting: A Feasibility, Leah Jane Epton Jan 2025

The Implementation Of The Queensland Health Smoking Cessation Clinical Pathway In A Western Australian Private Hospital Setting: A Feasibility, Leah Jane Epton

Theses

As smoking is prohibited on most hospital grounds, hospitalisation presents a valuable opportunity for healthcare professionals to identify smokers, administer smoking cessation treatments, and ensure appropriate inpatient support, as well as continued follow-up on discharge. It has been reported both anecdotally and in published research that encouragement from a health professional is a significant external prompt for a smoker to attempt quitting. It has also been noted in the inpatient setting, one in every 33 conversations will lead to the successful cessation of smoking.

More broadly, a 2012 Cochrane review on smoking cessation interventions for inpatients identified that they are …


Defining Barriers In Pulmonary Hypertension: Pulmonary Hypertension In Remote And Rural Settings In Australia: An Epidemiologic Study Aided By Echocardiography, Pyi Naing Jan 2025

Defining Barriers In Pulmonary Hypertension: Pulmonary Hypertension In Remote And Rural Settings In Australia: An Epidemiologic Study Aided By Echocardiography, Pyi Naing

Theses

Pulmonary hypertension (PH) is a common, complex, and potentially lethal haemodynamic condition with many underlying aetiologies. It is poorly understood, and diagnosis is usually made late in the disease process resulting in poor outcomes even in the developed world. An innovative universal framework is required to achieve early and accurate diagnosis for improved outcomes, especially in remote and rural areas. The thesis documents my substantial body of work that unlocks a collective framework to assist patients with PH, particularly in areas not classically serviced by tertiary level PH care.

The first chapter of my thesis outlines the history, important milestones …
