High-risk endometrial cancer has poor prognosis and is increasing in incidence. However, understanding of the molecular mechanisms which drive this disease is limited. We used genetically engineered mouse models (GEMM) to determine the functional consequences of missense and loss of function mutations in Fbxw7, Pten and Tp53, which collectively occur in nearly 90% of high-risk endometrial cancers. We show that Trp53 deletion and missense mutation cause different phenotypes, with the latter a substantially stronger driver of endometrial carcinogenesis. We also show that Fbxw7 missense mutation does not cause endometrial neoplasia on its own, but potently accelerates carcinogenesis caused by Pten …

Faculty, Staff and Student Publications

Inflammatory breast cancer (IBC) is an aggressive disease with a poor prognosis and a lack of effective treatments. It is widely established that understanding the interactions between tumor-associated macrophages (TAMs) and the tumor microenvironment is essential for identifying distinct targeting markers that help with prognosis and subsequent development of effective treatments. In this study, we present a 3D in vitro microfluidic IBC platform consisting of THP1 M0, M1, or M2 macrophages, IBC cells, and endothelial cells. The platform comprises a collagen matrix that includes an endothelialized vessel, creating a physiologically relevant environment for cellular interactions. Through the utilization of this …

A Comparative Analysis Of Adolescent Pregnancy Patient Outcomes In The United States And United Kingdom Healthcare Systems, Liza Hopper

Senior Theses

Individuals all across the world should have equal access to healthcare. However, one’s ability to receive and afford quality care differs between countries. Comparing the differences in healthcare structures in both the UK and the US provides great insight into how certain welfare models affect patient outcomes. In this project, I discuss the functionality of the healthcare systems in the UK and the US. Then, by delving into how they relate to adolescent pregnancy patient outcomes, one can compare how the healthcare policies relate to the patient outcomes of a vulnerable population group. In both countries, adolescent mothers, those who …

Neuromodulation For Adjunctive Treatment In Postmastectomy Pain Syndrome, Kennedy Kirkpatrick, Jay D Shah, Krishna Shah

Faculty, Staff and Students Publications

Postmastectomy pain syndrome (PMPS) affects nearly half of patients who undergo mastectomy to treat breast cancer. As the survival rate of breast cancer increases with advancements in treatment, the incidence of PMPS is also increasing. Patients with PMPS can experience unrelenting, chronic pain refractory to traditional management with oral pharmacotherapy in conjunction with nonpharmacologic treatment (physical therapy, transcutaneous electrical nerve stimulation (TENS)). Neuromodulation is an emerging treatment modality for numerous chronic pain conditions. This case report highlights the tremendous success of spinal cord stimulator placement for a patient with PMPS.

New Insights Into The Neuraminidase-Mediated Hemagglutination Activity Of Influenza A(H3n2) Viruses, Rongyuan Gao, Philippe Noriel Q Pascua, Ha T Nguyen, Anton Chesnokov, Chloe Champion, Vasiliy P Mishin, Dave E Wentworth, Larisa V Gubareva

Faculty, Staff and Student Publications

Influenza virus neuraminidase (NA) can act as a receptor-binding protein, a role commonly attributed to hemagglutinin (HA). In influenza A(H3N2) viruses, three NA amino acid residues have previously been associated with NA-mediated hemagglutination: T148, D151, and more recently, H150. These residues are part of the 150-loop of the NA monomer. Substitutions at 148 and 151 arise from virus propagation in laboratory cell cultures, whereas changes at 150 occurred during virus evolution in the human host. In this study, we examined the effect of natural amino acid polymorphism at position 150 on NA-mediated hemagglutination. Using the A/Puerto Rico/8/34 backbone, we generated …

We characterized a prospective endometrial carcinoma (EC) cohort containing 138 tumors and 20 enriched normal tissues using 10 different omics platforms. Targeted quantitation of two peptides can predict antigen processing and presentation machinery activity, and may inform patient selection for immunotherapy. Association analysis between MYC activity and metformin treatment in both patients and cell lines suggests a potential role for metformin treatment in non-diabetic patients with elevated MYC activity. PIK3R1 in-frame indels are associated with elevated AKT phosphorylation and increased sensitivity to AKT inhibitors. CTNNB1 hotspot mutations are concentrated near phosphorylation sites mediating pS45-induced degradation of β-catenin, which may render …

Faculty, Staff and Students Publications

BACKGROUND: Functional placental niches are presumed to spatially separate maternal-fetal antigens and restrict the vertical transmission of pathogens. We hypothesized a high-resolution map of placental transcription could provide direct evidence for niche microenvironments with unique functions and transcription profiles.

METHODS: We utilized Visium Spatial Transcriptomics paired with H&E staining to generate 17,927 spatial transcriptomes. By integrating these spatial transcriptomes with 273,944 placental single-cell and single-nuclei transcriptomes, we generated an atlas composed of at least 22 subpopulations in the maternal decidua, fetal chorionic villi, and chorioamniotic membranes.

FINDINGS: Comparisons of placentae from uninfected healthy controls (n = 4) with COVID-19 asymptomatic …

A Pre-Medical Student’S Reconciliation Of Feminist Narratives Regarding Women’S Health: A Consideration Of Perspectives On Childbirth In The U.S., Laura Clayton

sprinkle: an undergraduate journal of feminist and queer studies

Many feminists argue that one major negative aspect of reproductive healthcare in the U.S. is the common over-medicalization of women during childbirth, including potentially unnecessary procedures such as cesarean-section and episiotomy. As a solution, they advocate for increased involvement of midwives in childbirth practices, as midwives allow women to give birth at home with minimal medical intervention. This paper analyzes the benefits of midwifery as well as the current increased risk associated with homebirth in the U.S. Additionally, it questions the damaging stigma associated with assumptions of cesarean-section as a suboptimal outcome. A false dichotomy has developed in our culture …

Effects Of In Utero Etoh Exposure On 18s Ribosomal Rna Processing: Contribution To Fetal Alcohol Spectrum Disorder, Nune Darbinian, Gary L Gallia, Armine Darbinyan, Ekaterina Vadachkoria, Nana Merabova, Amos Moore, Laura Goetzl, Shohreh Amini, Michael E Selzer

Faculty, Staff and Student Publications

Fetal alcohol spectrum disorders (FASD) are leading causes of neurodevelopmental disability. The mechanisms by which alcohol (EtOH) disrupts fetal brain development are incompletely understood, as are the genetic factors that modify individual vulnerability. Because the phenotype abnormalities of FASD are so varied and widespread, we investigated whether fetal exposure to EtOH disrupts ribosome biogenesis and the processing of pre-ribosomal RNAs and ribosome assembly, by determining the effect of exposure to EtOH on the developmental expression of 18S rRNA and its cleaved forms, members of a novel class of short non-coding RNAs (srRNAs). In vitro neuronal cultures and fetal brains (11–22 …

Poverty And Commercial Surrogacy In India: An Intersectional Analytical Approach, Sheela Suryanarayanan

Dignity: A Journal of Analysis of Exploitation and Violence

The destination and source countries for commercial surrogacy match world patterns of inequality. India, Nepal, Thailand, Mexico, and Cambodia banned commercial surrogacy, moving the market to other less-developed countries in South Africa and South America. India had a commercial surrogacy boom until exploitative factors led to the passage of the Surrogacy (Regulation) Bill in 2019, which banned the practice. This paper examines surrogacy's monetary, health, and emotional effects on 45 surrogate mothers in Gujarat State, India. The study revealed that a majority (63%) of the very poor women remained very poor post-surgery. Surrogate mothers in poor households had to do …

Anthracycline-based chemotherapy is associated with increased subsequent breast cancer (SBC) risk in female childhood cancer survivors, but the current evidence is insufficient to support early breast cancer screening recommendations for survivors treated with anthracyclines. In this study, we pooled individual patient data of 17,903 survivors from six well-established studies, of whom 782 (4.4%) developed a SBC, and analyzed dose-dependent effects of individual anthracycline agents on developing SBC and interactions with chest radiotherapy. A dose-dependent increased SBC risk was seen for doxorubicin (hazard ratio (HR) per 100 mg m

Sepsis in obstetric care is one of the leading causes of maternal death in the United States, with Black, Asian/Pacific Islander, and American Indian/Alaska Native obstetric patients experiencing sepsis at disproportionately higher rates. State maternal mortality review committees have determined that deaths are preventable much of the time and are caused by delays in recognition, treatment, and escalation of care. The "Sepsis in Obstetric Care" patient safety bundle provides guidance for health care teams to develop coordinated, multidisciplinary care for pregnant and postpartum people by preventing infection and recognizing and treating infection early to prevent progression to sepsis. This is …

BACKGROUND: Increased duration of breastfeeding improves maternal cardiovascular health and may be especially beneficial in high-risk populations, such as those with chronic hypertension. Others have shown that individuals with hypertension are less likely to breastfeed, and there has been limited research aimed at supporting breastfeeding goals in this population. The impact of perinatal blood pressure control on breastfeeding outcomes among people with chronic hypertension is unknown.

OBJECTIVE: This study aimed to evaluate whether breastfeeding initiation and short-term duration assessed at the postpartum clinic visit differed according to perinatal blood pressure treatment strategy (targeting blood pressure <140/90 mm Hg vs reserving antihypertensive treatment for blood pressure ≥160/105 mm Hg).

The subcortical maternal complex (SCMC) is a multiprotein complex in oocytes and preimplantation embryos that is encoded by maternal effect genes. The SCMC is essential for zygote-to-embryo transition, early embryogenesis, and critical zygotic cellular processes, including spindle positioning and symmetric division. Maternal deletion of Nlrp2, which encodes an SCMC protein, results in increased early embryonic loss and abnormal DNA methylation in embryos. We performed RNA sequencing on pools of meiosis II (MII) oocytes from wild-type and Nlrp2-null female mice that were isolated from cumulus-oocyte complexes (COCs) after ovarian stimulation. Using a mouse reference genome-based analysis, we found 231 …
