Daam2 Gene Variants P.(Asp165glu) And P.(Asn614thrfster2) In Pediatric Cryptorchidism: A Hypothesis-Generating Pilot Case-Control Study From The Eastern Black Sea Region Of Türkiye ​, Onur Yalçin, Çağri Doğan

Turkish Journal of Medical Sciences

Background/aim: Cryptorchidism is the most common congenital anomaly of the male genitourinary system, characterized by a multifactorial etiology. The disheveled-associated activator of morphogenesis 2 (DAAM2) gene regulates androgen receptor (AR)- dependent transcription; its variants are associated with partial androgen insensitivity. Since the inguinoscrotal phase of testicular descent is androgen-dependent, we hypothesized that DAAM2 variants contribute to cryptorchidism susceptibility. This pilot study, designed to generate hypotheses rather than to establish association, investigated the frequency of two functionally characterized DAAM2 variants, p.(Asp165Glu) and p.(Asn614ThrfsTer2), in pediatric cryptorchidism.

The Brown Foundation: Institute of Molecular Medicine

We report a complete rodent telomere-to-telomere genome assembly from the brown rat, Rattus norvegicus. Annotation was enriched with multi-tissue long-read RNA sequencing and uncovered numerous novel genes. Assembly of both sex chromosomes reveals the absence of gene coding in the presumed pseudo-autosomal regions and the presence of centromeric satellite repeats on distal chromosome Y (chrY). We provide evidence of meiotic conjunction between Xp and Yq. The genome assembly reveals several expanded autosomal regions enriched for testis-expressed genes. Finally, we have generated a pangenome from recent high-quality assemblies of 8 distinct inbred rat strain genomes. This allows the strain-specific distribution of …

Bcg Overexpressing Ag85b Reprograms Host Immune Response Through Coordinated Transcriptional Networks, Vivek Chauhan, Rakesh Kumar, Raja Veerapandian, Enrique I. Ramos, Chinnaswamy Jagannath, Shrikanth Gadad, Subramanian Dhandayuthapani

School of Medicine Publications

Antigen 85B (Ag85B), an immunodominant protein secreted by Mycobacterium tuberculosis (Mtb), induces robust T-cell-mediated immunity in host cells. Previous studies have demonstrated that recombinant BCG strains overexpressing Ag85B (BCG85B) confer significant protection against tuberculosis in mouse models. This study hypothesized that enhanced protection by recombinant BCG85B results from modulation of host immune gene expression by the Ag85B antigen. To test this, RNA-seq analysis was performed on splenocytes from mice immunized with the wild-type BCG (BCG-WT) and BCG85B strains. Differentially expressed genes (DEGs) in the splenocytes of BCG85B-immunized mice indicated upregulation of immune-related KEGG pathways, including Th1/Th2 and Th17 differentiation, NF-kappa …


Mri-Based Estimation Of The Hip Joint Center In Infants Using Two Sphere-Fitting Methods, Victoria Melendez Aug 2026

Mri-Based Estimation Of The Hip Joint Center In Infants Using Two Sphere-Fitting Methods, Victoria Melendez

Discovery Day - Daytona Beach

Accurate estimation of the hip joint center (HJC) is critical for biomechanical modeling and clinical assessment. Common methods include predictive methods (e.g., regression equations) and functional methods such as sphere-fitting. In infants, femoral head-based methods are often limited due to incomplete ossification of the anatomy and poor visualization in computed tomography (CT) images. This study evaluates an alternative approach using MRI-based sphere fitting of the ossified acetabular rim, comparing its accuracy to traditional femoral head-based methods. MRI scans of three male infants (ages 10.7- 12.7 months) were used to manually place landmarks on the ossified acetabulum and the cartilaginous boundary …

Metabolic Regulation And Immunity In The Spaceflight Environment, Graeme Grainger, Riley Dienna, Astrid Senko, Angela Cebula, Arden Rodriguez Arden Rodriguez

Discovery Day - Daytona Beach

Long-duration spaceflight exposes astronauts to chronic ionizing radiation and microgravity that disrupts homeostasis in the immune system and cellular metabolism. While simulated spaceflight models demonstrate altered T-cell polarization and sex-dependent shifts toward regulatory phenotypes, the metabolic mechanisms driving these immune changes remain unclear. Immune cell function is tightly linked to metabolic programming, with effector T cells relying on glycolysis and regulatory T cells favoring oxidative metabolism, making them highly sensitive to shifts in nutrient availability and redox balance. Emerging research further suggests that neutrophils act as metabolic regulators capable of reshaping the immune microenvironment through oxidative stress, cytokine production, and …


Transient Activation Of Potent Progenitor Cells Is Required For Spinal Cord Regeneration, Chase Alexander Weinholtz Aug 2026

Transient Activation Of Potent Progenitor Cells Is Required For Spinal Cord Regeneration, Chase Alexander Weinholtz

Arts & Sciences Graduate Student Theses and Dissertations

Mammalian spinal cord injury is an intractable biomedical problem driven by interlocking maladaptive cellular responses that prioritize acute stabilization over long-term recovery. However, this deficient regenerative capacity is not an inherent limitation. The zebrafish, for example, capably regenerates and regains motor function with 2 months of a full transection injury. This ability is thought to rely on the transient expansion of stem cell-like progenitors marked by sox2 expression. Yet our understanding of the identities and contributions of this crucial population remains limited. Here, we determine the molecular identities and cellular contributions of sox2+ progenitors during innate spinal cord repair in …

Relationship Identification Between Triggers And Changes In The Brain And The Overall Human Electrophysiology During Migraines, Dominic Sandell, Jonah Dematto, Gianpiero Lara, Jasmine Rosales, Legacy Wilson, Zachary Young

Discovery Day - Daytona Beach

One of the most common neurological conditions in the world is migraines; nearly 1/4th of the working population suffers from this condition and exhibits a large variety of triggers. The current treatment method for migraine uses few different medications for all migraines, regardless of triggers. Our hypothesis is that there is a specific relationship between the triggers of migraines and the electrical changes in the brain during migraines. It is known that electrical activity in the brain occurs during migraines; it is unclear whether these changes differ across triggers. The study incorporates two different data collection methods: electrophysiological tests (Electroencephalogram …


Using H2ax As A Biological Indicator To Assess Radiation-Induced Bone Loss In Microgravity Environments, Angeline Nichols, Enoch Tonkin, Ana Lobaton, Jahzara Hope Aug 2026

Using H2ax As A Biological Indicator To Assess Radiation-Induced Bone Loss In Microgravity Environments, Angeline Nichols, Enoch Tonkin, Ana Lobaton, Jahzara Hope

Discovery Day - Daytona Beach

Long-duration space missions expose astronauts to microgravity and chronic low-dose radiation, both greatly impacting skeletal health. While mechanical unloading in microgravity is a well-known driver of bone loss, recent evidence indicates that radiation independently contributes to bone deterioration by increasing osteoclast activity, which remodel bone faster, and suppress osteoblast differentiation. H2AX, a histone protein that rapidly phosphorylates into y-H2AX in response to the double strands of DNA breaking, has emerged as a sensitive biological marker for radiation exposure. This project aims to determine the efficacy of H2AX in the presence of radiation-induced DNA damage in bone marrow, compared to microgravity …

The Effect Of Snris On Pilot Reaction Time In Simulated Flight, Isabella Owen, Aidan Roach, Micah Henry, Casey Tressler

Discovery Day - Daytona Beach

Many aviators who are prescribed serotonin and norepinephrine reuptake inhibitors (SNRI) or selective serotonin reuptake inhibitors (SSRI) to treat mental health disorders such as major depressive disorder, general anxiety disorder, or post-traumatic stress disorder must halt their duties for a set amount of time. This is due to aviation authorities having data that suggests SNRIs and SSRIs lead to inhibitions in mental processes that can cause crashes or death. Most of the research that has been conducted examined the effects of SSRIs on individuals without mental health disorders in non-flight settings. This study will explore the effect SNRIs have on …

Center for Translational Medicine Faculty Papers

Airway smooth muscle (ASM) is a key determinant of airway caliber and a major contributor to structural remodeling in obstructive lung diseases, including asthma and COPD. ASM proliferation is regulated by transcriptional and post-transcriptional mechanisms, including ubiquitin-dependent protein turnover mediated by E3 ubiquitin ligases. Here, we investigated the role of the RING-type E3 ligase RNF145 in mitogenic signaling and ASM cell proliferation. Human ASM cells were transfected with RNF145 shRNA or treated with the E3 ligase inhibitor SMER3, followed by stimulation with fetal bovine serum (FBS) or platelet-derived growth factor (PDGF). RNF145 knockdown or SMER3 treatment dose-dependently inhibited mitogen-induced ASM …
