Aging Differentially Affects Axonal Autophagosome Formation And Maturation, Heather Tsong, Erika Lf Holzbaur, Andrea Kh Stavoe

Faculty, Staff and Student Publications

Misregulation of neuronal macroautophagy/autophagy has been implicated in age-related neurodegenerative diseases. We compared autophagosome formation and maturation in primary murine neurons during development and through aging to elucidate how aging affects neuronal autophagy. We observed an age-related decrease in the rate of autophagosome formation leading to a significant decrease in the density of autophagosomes along the axon. Next, we identified a surprising increase in the maturation of autophagic vesicles in neurons from aged mice. While we did not detect notable changes in endolysosomal content in the distal axon during early aging, we did observe a significant loss of acidified vesicles …

Emerging evidence suggests that cryptic translation beyond the annotated translatome produces proteins with developmental or physiological functions. However, functions of cryptic non-canonical open reading frames (ORFs) in cancer remain largely unknown. To fill this gap and systematically identify colorectal cancer (CRC) dependency on non-canonical ORFs, we apply an integrative multiomic strategy, combining ribosome profiling and a CRISPR-Cas9 knockout screen with large-scale analysis of molecular and clinical data. Many such ORFs are upregulated in CRC compared to normal tissues and are associated with clinically relevant molecular subtypes. We confirm the in vivo tumor-promoting function of the microprotein SMIMP, encoded by a …

The transferability and clinical value of genetic risk scores (GRSs) across populations remain limited due to an imbalance in genetic studies across ancestrally diverse populations. Here we conducted a multi-ancestry genome-wide association study of 156,319 prostate cancer cases and 788,443 controls of European, African, Asian and Hispanic men, reflecting a 57% increase in the number of non-European cases over previous prostate cancer genome-wide association studies. We identified 187 novel risk variants for prostate cancer, increasing the total number of risk variants to 451. An externally replicated multi-ancestry GRS was associated with risk that ranged from 1.8 (per standard deviation) in …

BACKGROUND: The prevalence, prediction and impact of acute kidney injury (AKI) in alcohol-related hepatitis (AH) is uncertain.

AIMS: We aimed to determine AKI incidence; association with mortality; evaluate serum biomarkers and the modifying effects of prednisolone and pentoxifylline in the largest AH cohort to date.

METHODS: Participants in the Steroids or Pentoxifylline for Alcoholic Hepatitis trial with day zero (D0) creatinine available were included. AKI was defined by modified International Club of Ascites criteria; incident AKI as day 7 (D7) AKI without D0-AKI. Survival was compared by Kaplan-Meier; mortality associations by Cox regression; associations with AKI by binary logistic regression; …

Plastic, It's What's For Dinner: A Preliminary Comparison Of Ingested Particles In Bottlenose Dolphins And Their Prey, Leslie B Hart, Miranda Dziobak, Randall S Wells, Elizabeth Berens Mccabe, Eric Conger, Tita Curtin, Maggie Knight, John Weinstein

Faculty, Staff and Student Publications

Microplastic ingestion was reported for common bottlenose dolphins (Tursiops truncatus) inhabiting Sarasota Bay, FL, USA, a community that also has prevalent exposure to plasticizers (i.e., phthalates) at concentrations higher than human reference populations. Exposure sources are currently unknown, but plastic-contaminated prey could be a vector. To explore the potential for trophic exposure, prey fish muscle and gastrointestinal tract (GIT) tissues and contents were screened for suspected microplastics, and particle properties (e.g., color, shape, surface texture) were compared with those observed in gastric samples from free-ranging dolphins. Twenty-nine fish across four species (hardhead catfish, Ariopsis felis; pigfish, Orthopristis …

Faculty, Staff and Student Publications

BACKGROUND: Laparoscopic splenectomy (LS), a treatment for both benign and malignant splenic diseases, can prove technically challenging in patients with massive splenomegaly. In particular, the optimal surgical modality for treating massive splenomegaly in children remains controversial.

METHODS: The clinicopathologic data of 289 pediatric patients undergoing splenectomy for massive splenomegaly were studied in a retrospective analysis. Accordingly, the patients were classified into the LS surgery group and open splenectomy (OS) surgery group. In the laparoscopy cohort, they were separated into two subgroups according to the method of surgery: the multi-incision laparoscopic splenectomy (MILS) and the single-incision laparoscopic splenectomy (SILS) surgery groups, …

Effects Of Antiresorptive Medications On Tooth Root Formation And Tooth Eruption In Paediatric Patients, Yuki Arai, Jeryl D English, Noriaki Ono, Wanida Ono

Faculty, Staff and Student Publications

Tooth eruption is a pivotal milestone for children's growth and development. This process involves with the formation of the tooth root, the periodontal ligament (PDL) and the alveolar bone, as the tooth crown penetrates the bone and gingiva to enter the oral cavity. This review aims to outline current knowledge of the adverse dental effects of antiresorptive medications. Recently, paediatric indications for antiresorptive medications, such as bisphosphonates (BPs), have emerged, and these agents are increasingly used in children and adolescents to cure pathological bone resorption associated with bone diseases and cancers. Since tooth eruption is accompanied by osteoclastic bone resorption, …

Multi-Omics Analysis In Developmental Bone Biology, Yuki Matsushita, Azumi Noguchi, Wanida Ono, Noriaki Ono

Faculty, Staff and Student Publications

Single-cell omics and multi-omics have revolutionized our understanding of molecular and cellular biological processes at a single-cell level. In bone biology, the combination of single-cell RNA-sequencing analyses and in vivo lineage-tracing approaches has successfully identified multi-cellular diversity and dynamics of skeletal cells. This established a new concept that bone growth and regeneration are regulated by concerted actions of multiple types of skeletal stem cells, which reside in spatiotemporally distinct niches. One important subtype is endosteal stem cells that are particularly abundant in young bone marrow. The discovery of this new skeletal stem cell type has been facilitated by single-cell multi-omics, …

Role Of The Immune System In Liver Transplantation And Its Implications For Therapeutic Interventions, Guanrong Chen, Xin Hu, Yingchen Huang, Xiaonan Xiang, Sheng Pan, Ronggao Chen, Xiao Xu

Faculty, Staff and Student Publications

Liver transplantation (LT) stands as the gold standard for treating end-stage liver disease and hepatocellular carcinoma, yet postoperative complications continue to impact survival rates. The liver's unique immune system, governed by a microenvironment of diverse immune cells, is disrupted during processes like ischemia-reperfusion injury posttransplantation, leading to immune imbalance, inflammation, and subsequent complications. In the posttransplantation period, immune cells within the liver collaboratively foster a tolerant environment, crucial for immune tolerance and liver regeneration. While clinical trials exploring cell therapy for LT complications exist, a comprehensive summary is lacking. This review provides an insight into the intricacies of the liver's …

Basket, umbrella, and platform trial designs (master protocols) have emerged over the last decade to study precision medicine approaches in oncology. First-generation trials like NCI-MATCH (Molecular Analysis for Therapy Choice) have proven the principle that studying targeted therapies on a large scale is feasible both from the laboratory and clinical perspectives. However, single-agent targeted therapies have shown limited ability to control metastatic disease, despite careful matching of drug to target. As such, newer approaches employing combinations of targeted therapy, or targeted therapy with standard therapies, need to be considered. The NCI has recently embarked on three second-generation precision medicine trials …

Temporal Artery Pseudoaneurysm In A Pediatric Patient, Gowri Gowda, Donald Mendoza, Amanda Tullos, Jessica Zagory, Malachi Sheahan

School of Medicine Faculty Publications

Superficial temporal artery pseudoaneurysms are an uncommon vascular pathology that can present after head or facial trauma. Furthermore, they are rarely reported in the pediatric population. Ultrasound can be a useful tool in the diagnosis because it is easily accessible and can be rapidly acquired. We report a case that demonstrates the utility of ultrasound in the diagnosis of a superficial temporal artery pseudoaneurysm.

Using Plastinated Cadaveric Models For Anatomical Study Of Dorsalis Pedis Artery And Its Variation, Steven Bolton, Ifunanya Monube, Hooman Tabatabai-Mir

School of Podiatric Medicine - Student Research

The dorsalis pedis artery is a main artery of the dorsum of the foot. It directly arises from the anterior tibial artery and travels distally to the base of the 1st metatarsal. Its main function includes supplying oxygenated blood to the dorsal surface of the foot. A weak dorsalis pedis pulse is an indication of underlying circulation issue, such as peripheral vascular disease. Anatomical variations of the artery are not uncommon, including the total absence of the artery. Branching variations occur in approximately 10% of the population. Knowledge of these variations is critical for surgeons to prevent surgical complications

Biomedical Sciences

Sprouty4 (SPRY4) has been frequently reported as a tumor suppressor and is therefore downregulated in various cancers. For the first time, we report that SPRY4 is epigenetically upregulated in colorectal cancer (CRC). In this study, we explored DNA methylation and hydroxymethylation levels of SPRY4 in CRC cells and patient samples and correlated these findings with mRNA and protein expression levels. Three loci within the promoter region of SPRY4 were evaluated for 5mC levels in CRC using the combined bisulfite restriction analysis. In addition, hydroxymethylation levels within SPRY4 were measured in CRC patients. Lastly, DNA methylation and mRNA expression data were …

Cyclin D1 Extensively Reprograms Metabolism To Support Biosynthetic Pathways In Hepatocytes, Heng Wu, Betsy T. Kren, Andrew N. Lane, Teresa A. Cassel, Richard M. Higashi, Teresa Whei-Mei Fan, George S. Scaria, Laurie L. Shekels, Mark A. Klein, Jeffrey H. Albrecht

Markey Cancer Center Faculty Publications

Cell proliferation requires metabolic reprogramming to accommodate biosynthesis of new cell components, and similar alterations occur in cancer cells. However, the mechanisms linking the cell cycle machinery to metabolism are not well defined. Cyclin D1, along with its main partner cyclindependent kinase 4 (Cdk4), is a pivotal cell cycle regulator and driver oncogene that is overexpressed in many cancers. Here, we examine hepatocyte proliferation to define novel effects of cyclin D1 on biosynthetic metabolism. Metabolomic studies reveal that cyclin D1 broadly promotes biosynthetic pathways including glycolysis, the pentose phosphate pathway, and the purine and pyrimidine nucleotide synthesis in hepatocytes. Proteomic …

Immunization With The Amino-Terminus Region Of Dense Granule Protein 6 (Gra6) Of Toxoplasma Gondii Activates Cd8+ Cytotoxic T Cells Capable Of Removing Tissue Cysts Of The Parasite Through Antigen Presentation By Human Hla-A2.1, Rajesh Mani, Corinne Mercier, Marie-France Delauw, Yasuhiro Suzuki

Markey Cancer Center Faculty Publications

CD8þ T cells from HLA-A2.1-transgenic mice, but not wild-type mice, immunized with the amino- terminus region (aa 41e152) of dense granule protein 6 (GRA6Nt) of Toxoplasma gondii secreted large amounts of perforin and granzyme B in response to GRA6Nt through antigen presentation by HLA-A2.1 in vitro. When those CD8þ T cells were transferred into chronically infected HLA-A2.1-expressing NSG mice deficient in T cells, cerebral cyst burden of the recipients of HLA-A2.1-transgenic T cells, but not of WT T cells, became significantly less than that of control mice with no cell transfer. Furthermore, the significant reduction of the cyst burden by …

Markey Cancer Center Faculty Publications

Dysregulated eEF2K expression is implicated in the pathogenesis of many human cancers, including triple-negative breast cancer (TNBC), making it a plausible therapeutic target. However, specific eEF2K inhibitors with potent anti-cancer activity have not been available so far. Targeted protein degradation has emerged as a new strategy for drug discovery. In this study, a novel small molecule chemical is designed and synthesized, named as compound C1, which shows potent activity in degrading eEF2K. C1 selectively binds to F8, L10, R144, C146, E229, and Y236 of the eEF2K protein and promotes its proteasomal degradation by increasing the interaction between eEF2K and the …

NUT carcinoma (NC) is an aggressive carcinoma driven by the BRD4-NUT fusion oncoprotein, which activates chromatin to promote expression of pro-growth genes. BET bromodomain inhibitors (BETi) are a promising treatment for NC that can impede BRD4-NUT’s ability to activate genes, but the efficacy of BETi as monotherapy are limited. Here, we demonstrated that EZH2, which silences genes through establishment of repressive chromatin, is a dependency in NC. Inhibition of EZH2 with the clinical compound tazemetostat (taz) potently blocked growth of NC cells. Epigenetic and transcriptomic analysis revealed that taz reversed the EZH2-specific H3K27me3 silencing mark and restored expression of multiple …
