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 …

Tracking Community Outreach And Engagement Activities Among National Cancer Institute-Designated Cancer Centers, Todd Burus, Caree R. Mcafee, Pamela C. Hull, Amy E. Leader, Christopher Mcnair

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 …

Biparental Inheritance Of Germline-Specific Chromosomes In The Sea Lamprey And Their Roles In Oocytes, Vladimir A. Timoshevskiy, Nataliya Timoshevskaya, Kaan İ. Eşkut, Kasturi Rajandran, Jeramiah J. Smith

Markey Cancer Center Faculty Publications

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 …

Cryptic To Conventional Cytogenetics: Philadelphia- Like All Presenting With Hypereosinophilia, Zena Chahine, Leonard Yenwong Fai, Sainan Wei, Ayman Qasrawi

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 …

Cabozantinib Selectively Induces Proteasomal Degradation Of P53 Somatic Mutant Y220c And Impedes Tumor Growth, Fang Lin Lv, Lu Zhang, Cheng Ji, Lei Peng, Mingxian Zhu, Shumin Yang, Shunli Dong, Mingxuan Zhou, Fanfan Guo, Zhenyun Li, Fang Wang, Youguo Chen, Jinhua Zhou, Xingcong Ren, Genhai Shen, Jin-Ming Yang, Bin Li, Yi Zhang

Markey Cancer Center Faculty Publications

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

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 …

Markey Cancer Center Faculty Publications

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 …

Hsp47 Drives Obesity-Associated Breast Cancer Progression By Enhancing Asporin Deposition In Adipose Tissue, Gaofeng Xiong, Daheng He, Dana L. Napier, Jing Chen, Haizhu Shi, Chun Li, Paula J. Hurley, Chi Wang, Haining Zhu, Changcheng Zhou, Therese J. Bocklage, Ren Xu

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. …

Implementing A Chatbot To Promote Hereditary Breast & Ovarian Cancer Genetic Screening In Women's Health: Identifying Barriers And Facilitators To Screening Adoption, Easton N. Wollney, Shireen Madani Sims, Luisel J. Ricks-Santi, Elizabeth Eddy, Daniel Wiesman, Carla L. Fisher

Department of Biomedical and Translational Sciences Faculty Publications

Background

To promote genetic screening among women at risk for hereditary breast and ovarian cancer (HBOC), the American College of Obstetricians and Gynecologists recommends that risk assessment be integrated into practice. Chatbots like the Genetic Information Assistant (Gia®) are increasingly implemented to expand access to hereditary genetic screening. Factors that impact chatbot implementation for HBOC risk screening and women's uptake are not fully realized. To refine implementation strategies prior to full scale implementation, we sought to identify women's perceived facilitators/barriers to adopting Gia screening in a rural population within a large healthcare system in the southern United States.

Pediatric Cancer Incidence, Temporal Trends, And Mortality In The United States By Health Disparities Indicators, Seer (1973-2014), Prachi P. Chavan, Laurens Holmes Jr.

Epidemiology, Biostatistics, & Environmental Health Faculty Publications

Background: Pediatric cancer incidence has been increasing in the United States, despite improvement in pediatric cancer survival. This steady increase in incidence trends is not completely understood but maybe associated with social and environmental factors. In this study we aimed to assess the cumulative incidence, temporal trends, and mortality rates in pediatric cancer. Additionally, we examined sub-group variability in both incidence and mortality rates. Methods: Data from Surveillance, Epidemiology, and End Results (SEER) −18 from 1973–2014 were used for the purpose of analysis in this study. Age-adjusted incidence rates were used to assess temporal trends in cancer among children aged < 1–19 years. Univariable and multivariable binomial regression models were used to examine the association between race and cancer mortality while adjusting for potential confounders. Results: There were 92,594 cancer diagnoses during this period. White children comprised 74,758, (80.7%), black children 10,030, (10.8%), and other races 6648, (7.2%). Overall the age-adjusted cumulative incidence was slightly higher among white children (16.4%) than black children (12.4%) and other (13.0%). Children aged 15–19 years and those in metropolitan regions were more likely to be diagnosed with pediatric cancer. Relative to females, males were 16% more likely to die from the disease [adjusted Risk Ratio (aRR): 1.16, 95% Confidence Interval (CI): 1.09–1.22]. Additionally, compared to white children, black children had higher mortality rates [(aRR): 1.37, 99% CI: 1.23–1.52]. Conclusions: There is an increasing trend in pediatric cancer incidence; while white children have the highest incidence, black children and males indicated a survival disadvantage, indicative of racial and sex variability in overall pediatric cancer in the United States.
