Musculoskeletal injury risk in midlife women has traditionally been attributed to estrogen decline, but this narrow focus overlooks the broader biomechanical, neuromuscular, and structural changes associated with menopause. Estrogen plays a multisystem role in maintaining trabecular bone integrity, collagen turnover, and neuromuscular coordination. Its abrupt loss causes bone demineralization (2%-5% annually in early menopause), impairs tendon repair, and contributes to sarcopenia. Fluctuating estradiol levels during perimenopause may transiently increase ligament laxity, further destabilizing joints. Common injuries such as Achilles and rotator cuff tendinopathies, plantar fasciitis, and stress fractures are amplified by low bone mineral density, prior fracture history, aromatase inhibitor …

A Role For The Poly-Asparagine Repeat In The Plasmodium Histone Acetyltransferase, Pfgcn5, Kelly Rubiano, Aaron Morris, Francisca D L Vitorino, Jasper Travis, Benjamin A Garcia, Sumit Mukherjee, Daniel E Goldberg

2020-Current year OA Pubs

Plasmodium falciparum possesses one of the most AT-rich genomes in nature (80.6%). A consequence is an asparagine-rich proteome. A quarter of P. falciparum proteins possess poly-asparagine repeats that can extend more than 100 residues. The role of these repeats has remained a mystery in the biology of this parasite. Here, we report that the poly-asparagine repeat-containing Nterminus of the histone acetyltransferase PfGCN5 associates with the C-terminal catalytic domain after cleavage in the nucleus. Deletion of the repeat destabilizes the N-terminal polypeptide, leading to impaired parasite development and growth, particularly under stress conditions. Using high-resolution mass spectrometry and western blotting analysis, …

Cap1 (Cyclase-Associated Protein 1) Mediates The Camp Regulation Of Adhesion And Proliferation Of Schwann Cells In The Peripheral Nervous System, Jarna Karmoker

Student Theses and Dissertations

The peripheral nervous system relays signals between the central nervous system and the rest of the body, and peripheral nerve injuries and neuropathies can cause permanent neurological deficits. Schwann cells (SCs) are glial cells that myelinate neurons, which is essential for neuronal function and nerve repair. CAP1 (Cyclase-Associated Protein 1) is best characterized as an actin-regulating protein, while it also regulates other cellular processes, including matrix adhesion, migration, and proliferation. We discovered that cAMP-induced CAP1 dephosphorylation regulates relevant cell functions. While cAMP is also important for SC function and myelination, the underlying mechanisms remain largely unknown. We silenced CAP1 in …

Assessing The Effectiveness Of Wetland Reserve Easements As Habitat For Birds In The Mississippi Alluvial Valley Of Eastern Arkansas, Colin K. Dobson

Student Theses and Dissertations

Globally, wetland habitats suffered major declines during the 20th century. In the 1990s, the United States government created the Wetland Reserve Program (later consolidated into the Agricultural Conservation Easement Program), to combat the loss of wetlands. Despite success in attracting landowners, minimal monitoring of properties enrolled into the program (easements) has occurred. In this study, we monitored avian communities at easements, compared avian diversity at easements to agriculture and bottomland forests, and quantified microhabitat, site-specific, and surrounding landscape features at easements. We also studied the demographic rates of an indicator species of bottomland forests, the Prothonotary Warbler (Protonotaria citrea) at …

Enhancer Rna Transcription Near Segmentation Gene Enhancers Can Be Analyzed In Situ Using Fish, Christine Mau, Benjamin Schmid, Ezzat El-Sherif

School of Integrative Biological & Chemical Sciences Faculty Publications

Enhancer RNAs (eRNAs) are non-coding transcripts produced at enhancer regions, which appear to be involved in transcriptional regulation. Up to date, these have been primarily investigated using labor- and cost-intensive genomic techniques. However, the precise mechanisms by which eRNA transcription or eRNA transcripts themselves mediate transcriptional regulation remain unclear. Here, we present a novel experimental approach that allows us to analyze characteristics of eRNA transcription in fixed and live whole Drosophila melanogaster embryos. We employ the anterior–posterior patterning genes as a model system to investigate the dynamics of eRNA expression, utilizing an imaging-based approach. We combined high-sensitivity fluorescence in situ …


From Athens To Jerusalem: Platonism, Richard Owen, And The Road Not Taken In Biology, Michael A. Flannery Jun 2026

From Athens To Jerusalem: Platonism, Richard Owen, And The Road Not Taken In Biology, Michael A. Flannery

Libraries Professional Work

Tertullian provocatively asked (circa 200 AD), “What indeed has Athens to do with Jerusalem? What concord is there between the Academy and the Church?” The relationship between formal philosophy and religion has been a contentious battleground ever since. It has historically come into sharpest focus in biology generally, and evolutionary theory specifically. Charles Darwin clearly won the day in the short-term. His evolutionary functionalism looked like an inglorious abandonment of time-honored metaphysical realism for positivist empirical reductionism with a concomitant horizontalization of perspective that has secularized and flattened the intellectual landscape. But more recently the rise of evo-devo (evolutionary developmental …

Mitochondria are hubs of metabolism and signaling. We previously demonstrated the importance of mitochondrial structure and function in chemotherapy-refractory triple-negative breast cancer (TNBC). Herein, we present the first 3D analysis of mitochondrial networks in human tumor tissues. Using serial block face scanning electron microscopy, we reconstructed 3,750 mitochondria and 800 lipid droplets (LDs) in naive and residual tumors persisting after conventional chemotherapies in two orthotopic patient-derived xenografts (PDX). Chemotherapies administered as monotherapy or in combination produced residual tumors that harbored mitochondria with significantly increased areas, volumes, and perimeters. We observed substantial reduction of mitochondrial intratumor heterogeneity following all treatments. Further, …

Age-related decline in oocyte quality increases the risk of infertility, miscarriage, and birth defects. Mitochondrial dysfunction is a key contributor to this decline. Here, we report that oocyte-specific deletion of Uba3, which encodes the catalytic subunit of the E1 NEDDylation-activating complex, causes sterility in mice. Fully grown, germinal vesicle–stage Uba3 conditional knockout oocytes exhibit mitochondrial dysfunction, including elevated reactive oxygen species, impaired oxidative phosphorylation, and depletion of mitochondrially encoded RNA transcripts. Proteomic analysis identified alterations in mitochondrial-associated proteins, including enrichment of mitochondrial matrix and respiratory chain components and reduced abundance of electron transport chain complexes. These defects were associated …
