The Role Of Recruited Adipose Stromal Cells And Their Fibroblastic Differentiation In Cancer, Lingyi Cai, Mikhail G Kolonin, Dimitris Anastassiou

Faculty, Staff and Student Publications

Adipose stromal cells (ASCs) are perivascular mesenchymal progenitors of adipose tissue. In cancer patients, ASCs can mobilize and migrate to the tumor, where they subsequently play an important role in cancer progression. This biological process involves the conversion of recruited ASCs into cancer-associated fibroblasts (CAFs). ASC-derived CAFs influence the tumor microenvironment through extracellular matrix remodeling, vascularization, and immunomodulation. These and other processes mediated by secreted paracrine factors also affect gene expression in carcinoma cells to promote the epithelial-mesenchymal transition (EMT), metabolic adaptation, survival, and invasiveness of cancer cells. ASC-derived CAFs can enhance tumor aggressiveness, accounting in part for the link …

Cathartocytosis: Jettisoning Of Cellular Material During Reprogramming Of Differentiated Cells, Jeffrey W Brown, Xiaobo Lin, Gabriel Anthony Nicolazzi, Xuemei Liu, Thanh Nguyen, Megan D Radyk, Joseph Burclaff, Jason C Mills

Faculty, Staff and Students Publications

Injury causes differentiated cells to undergo massive reprogramming to become proliferative and repair tissue via paligenosis. Gastric chief cells use paligenosis to reprogram into progenitor-like spasmolytic-polypeptide-expressing metaplasia (SPEM) cells. Stage 1 of paligenosis is the downscaling of mature cell architecture via a process involving lysosomes. Here, we notice that sulfated glycoproteins are not only digested during paligenosis but also excreted into the gland. Various genetic and pharmacological approaches show that endoplasmic reticulum membranes and secretory granule cargo are also excreted and that the process proceeds in parallel with but is mechanistically independent of autophagy. Three-dimensional light and electron microscopy demonstrated …

Montserrat Developments Impacting Local Coral Reefs, Emma I. Bartholomew

2025 Symposium

Montserrat is a small island in the Caribbean, and over half of the island is in the exclusion zone because of the active volcano, Soufrière Hills. In that half was the old capital, Plymouth, which has since been abandoned, and its old port. The old port was getting less reliable and accessible, so they decided to build a new port in Little Bay, closer to the seat of government in Brades. This study explored how the addition of the new port impacted the corals in that area. We explored several different bays and recorded the diversity and health of the …

Identification, Abundance, And Behavior Of North American Bobcat (Lynx Rufus) Along Road Mitigation Structures Designed For Endangered Species In South Texas, Victoria Hanley, Kevin W. Ryer, Md. Saydur Rahman, John H. Young Jr., Richard J. Kline

School of Integrative Biological & Chemical Sciences Faculty Publications

Endangered species are increasingly used as the target species in implementing and constructing new wildlife crossing structures (WCS). Highways in South Texas fragment the landscape and result in high road mortality for endangered species such as ocelots (Leopardus pardalis, a medium-sized spotted wild cat). In response, the Texas Department of Transportation constructed nine WCS on Farm-to-Market 106 (FM 106), a road which bisects Laguna Atascosa National Wildlife Refuge in Cameron County, Texas. With ocelots being rare and elusive, bobcats (Lynx rufus) are often used as a surrogate species to study felid behavior at road mitigation structures …

Heterogeneity Of Molecular Subtypes In Multifocal And Multicentric Breast Cancer, Anna M. Schmitz

Research from the Berry Summer Thesis Institute, 2025

Multifocal and multicentric breast cancers (MMBC), commonly referred to as multiple synchronous ipsilateral breast cancers, are heterogeneous diseases. There is a high degree of diversity between and within the tumors of a MMBC-bearing patient. Tumor heterogeneity can describe multiple features, such as morphological and molecular profiles. Knowledge about a patient's tumor heterogeneity can be used to determine a prognosis and treatment plan. However, transferring our growing knowledge of heterogeneity in MMBC into a clinical setting remains a challenge due to the large degree of diversity between tumor microenvironments and the cancer cells that tumors are composed of. This review article …

Crossroads Of Covid-19 And Alzheimer’S: Investigating Sars-Cov-2 Nsp6 And Orf7a In Amyloid-Β42 Toxicity, Jeffrey William Huettemann, Amit Singh

Research from the Berry Summer Thesis Institute, 2025

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) resulted in several hundred million contracted cases of coronavirus disease 2019 (COVID-19) and a global pandemic. In some of these cases, previous neurological diseases, such as Alzheimer’s disease (AD), seemed to progress much more rapidly after the COVID-19 infection. Thus, we became interested in studying the effects of SARS-CoV-2 infection on prior neurological disease progressions.

To modulate this condition, we used Drosophila melanogaster as a genetic model system. We had previously developed the Alzheimer’s Disease Fly Model with expression of human amyloid beta 42 (Aβ42) peptide, which is responsible for extracellular Aβ-42 …

A Mini Review On Rodent Models Of Autism Spectrum Disorder (Asd), Rachel Zeller

Research from the Berry Summer Thesis Institute, 2025

Autism spectrum disorder (ASD) is a neurodevelopmental disorder typically diagnosed at a young age. ASD symptoms include deficits in social behavior, repetitive and restrictive behaviors, anxiety, as well as alterations in sensory gating and sensitivity, learning, memory, and attention performance. Since ASD emerges from a combination of genetic and environmental factors, clinical treatment of these conditions presents with challenges. Being able to model behavioral and neurobiological aspects of this disorder at the preclinical level using rodents allows for further investigation of the pathophysiological basis of this disorder. This mini review will focus on selected genetic and pharmacological rodent models of …

Co-Culture 3d Model For Breast Cancer, Anh Duc Nguyen

Research from the Berry Summer Thesis Institute, 2025

The ability to replicate the tumor microenvironment using 3D models have allowed researchers to study the tumors in vitro closer to their in vivo counterparts without the drawbacks of those models. The 3D co-culture model is an improved version of the 3D monoculture model, capable of replicating the tumor microenvironment, letting researchers study cancer response mechanism, tumor metastases, drug resistance, simulate cell-cell interactions, etc., in breast cancer. The models can be classified into four classes based on their formation method and content, all of which have different advantages and disadvantages.

Evaluating The Environmental Determinants Of Tadpole Mouthpart Deformities, Nicholas J. Canfield

Research from the Berry Summer Thesis Institute, 2025

Amphibians are among the most threatened group of animals on the planet, with over 40% of living species facing an extinction risk. These organisms are highly sensitive to environmental change due to their highly permeable skin and complex life cycle that exposes them to stressors in both aquatic and terrestrial ecosystems. Amphibian populations that are closely monitored can serve as valuable bioindicators of environmental health because they typically respond rapidly to habitat degradation, decreased water quality, and changes in climate. Tadpoles in particular may act as a “canary in a coal mine” for aquatic ecosystems because they easily develop anatomical …

An Investigation Of Hydro-Morphological Changes At The Estuarine Outlet Of Kitchener Drain, Northern Coast Of Egypt, Nada Mansour, Karim Nassar, Mahmoud El-Gamal, Tharwat Sarhan

Mansoura Engineering Journal

In recent years, sedimentation and coastline erosion have occurred in the Kitchener Drain, where its outflow meets the Mediterranean Sea. Several measures have been taken to mitigate the impact of these problems. Excavation continues toward the drain's outlet, and there have been multiple stages of hard protection work, such as groins along the drain's eastern and western banks. What would happen if the working near the drain was kept, where accretion and erosion are most severe. The Coastal Modelling System (CMS) was used to find it out. The two-dimensional hydrodynamic circulation model known as the CMS is outfitted with modules …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Woody plants with green stems may have advantages over non-green-stemmed plants in that extra photosynthetic carbon gain has the potential to improve plant drought tolerance and aid drought recovery. However, most studies relating to green stem photosynthesis and drought tolerance have been conducted on non-horticultural plants under natural growing conditions. We investigated whether avocado green stem photosynthesis enhances drought tolerance and recovery. We applied light exclusion and drought treatments to 3-year-old potted trees of cultivars ‘Hass’ and ‘Fuerte’. Measurements of soil moisture, midday stem water potential, stem photosynthesis, bark chlorophyll concentration, concentration of sugars + starch and stem hydraulic conductivity …

While the cause of preterm birth (PTB) (i.e., delivery before 37 weeks of gestation) is likely multifactorial, ambient exposure to environmental chemicals has been postulated to play a role in its etiology. Our prior studies of exposure to polycyclic aromatic hydrocarbons (PAHs) in pregnancy have shown an increased level of placental PAH-induced bulky DNA adducts with increasing levels of PAH exposures. In this investigation, we hypothesized that higher levels of placental PAHs would be associated with an increased risk of PTB. Using gas chromatography and mass spectrometry (GC-MS/MS), we measured levels of benzo(a)pyrene (BaP), benzo(b)fluoranthene (BbF) and dibenz(a,h)anthracene (DBA) from …

Centrosomal And Non-Centrosomal Microtubule Networks Coordinate To Drive Nuclear Dynamics In Developing Epithelium, Rashmi Budhathoki

Electronic Theses and Dissertations

The morphogenesis of developing tissues relies on extensive cellular rearrangements in shape, position, and identity. A key process in reshaping tissues is cell intercalation-driven elongation, where epithelial cells align and intercalate along a common axis. Typically, analyses focus on how peripheral cortical forces influence cell shape changes. Less attention is given to how inhomogeneities in internal structures, particularly the nucleus, impact cell shaping. Here, we examine how pulsed contractile and extension dynamics interact with the nucleus in elongating Drosophila embryos. Our data show that tightly packed nuclei in apical layers hinder tissue remodeling/oscillatory behaviors. We identify two mechanisms for resolving …

Predicting Regional Cerebral Blood Flow Using Voxel-Wise Resting-State Functional Mri, Hongjie Ke, Bhim M Adhikari, Yezhi Pan, David B Keator, Daniel Amen, Si Gao, Yizhou Ma, Paul M Thompson, Neda Jahanshad, Jessica A Turner, Theo G M Van Erp, Mohammed R Milad, Jair C Soares, Vince D Calhoun, Juergen Dukart, L Elliot Hong, Tianzhou Ma, Peter Kochunov

Faculty, Staff and Student Publications

Background: Regional cerebral blood flow (rCBF) is a putative biomarker for neuropsychiatric disorders, including major depressive disorder (MDD).

Methods: Here, we show that rCBF can be predicted from resting-state functional MRI (rsfMRI) at the voxel level while correcting for partial volume averaging (PVA) artifacts. Cortical patterns of MDD-related CBF differences decoded from rsfMRI using a PVA-corrected approach showed excellent agreement with CBF measured using single-photon emission computed tomography (SPECT) and arterial spin labeling (ASL). A support vector machine algorithm was trained to decode cortical voxel-wise CBF from temporal and power-spectral features of voxel-level rsfMRI time series while accounting for PVA. …

Role Of Nucleic Acids As Chaperones In Protein Folding, Zijue Huang

Electronic Theses and Dissertations

Many proteins have slow folding times in vitro that are physiologically untenable. To combat this challenge, ATP-dependent chaperonins are thought to possess the unique ability to catalyze protein folding. Performing quantitative model selection using protein folding and unfolding data, we here show that short nucleic acids containing Gquadruplex (G4) structure can also catalyze protein folding. Performing the experiments as a function of temperature demonstrates that the G4 reshapes the underlying driving forces of protein folding. To understand the structural basis of this catalytic activity, we introduce NMR method to solve the structures, at base-level resolution, of a multiconformer G4 with …
