Faculty, Staff and Student Publications

Poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors, such as olaparib, talazoparib, rucaparib, and niraparib, comprise a therapeutic class that targets PARP proteins involved in DNA repair. Cancer cells with homologous recombination repair defects, particularly BRCA alterations, display enhanced sensitivity to these agents because of synthetic lethality induced by PARP inhibitors. These agents have significantly improved survival outcomes across various malignancies, initially gaining regulatory approval in ovarian cancer and subsequently in breast, pancreatic, and prostate cancers in different indications. This review offers a comprehensive clinical overview of PARP inhibitor approvals, emphasizing their efficacy across different cancers based on landmark phase 3 clinical …

Faculty, Staff and Student Publications

The variant single nucleotide polymorphism rs8104571 has been associated with poor outcomes following traumatic brain injury (TBI) and is most prevalent in those of African ancestry. This single nucleotide polymorphism (SNP) resides within a gene coding for the TRPM4 protein, which complexes with SUR1 protein to create a transmembrane ion channel and is believed to contribute to cellular swelling and cell death in neurological tissue. Our study evaluates the relationship between circulating TRPM4 and SUR1, rs8104571 genotype, and clinical outcome in TBI patients. Trauma patients with moderate to severe TBI were included in this retrospective study. rs8104571 genotyping and admission …

Faculty, Staff and Student Publications

The cytoplasmic domain of MHC class I (MHC-I) molecules contains a single, highly conserved tyrosine residue (Y320). In previous work, we found that mice expressing a Y320F-mutated form of H-2Kb had reduced capacity to generate Kb-restricted cytotoxic T lymphocyte (CTL) responses following viral infection, due at least in part to defects in endolysosomal trafficking of H-2Kb and antigen cross-presentation by dendritic cells (DCs). In this study, we investigated whether there are additional, post-presentation dependencies on Y320 for T cell priming. We engineered both human- and mouse-derived antigen-presenting cells (APCs) to express either wild-type MHC-I or variants of MHC-I containing Y320F …

The safe and effective delivery of curative cytotoxic chemotherapy for acute myeloid leukemia (AML) in patients receiving intermittent hemodialysis (IHD) for end-stage renal disease (ESRD) remains a clinical challenge; pharmacological and logistical barriers necessitate close interdisciplinary coordination. In this case, we report a 65-year-old female patient with chronic ESRD on IHD and newly diagnosed AML who achieved complete remission (CR) after treatment with fludarabine, idarubicin, and cytarabine plus venetoclax (i.e., FIA + venetoclax).

Autophagy Cargo Profiles In Skeletal Muscle During Starvation And Exercise, Mohd Farhan, Shangze Lyu, Trezze P Nguyen, Dakai Zhang, Hong Liang, Yong Zhou, Yu A An, Jun Wang, Hongyuan Yang, Guangwei Du, Yang Liu

Faculty, Staff and Student Publications

Autophagy is a cellular process to clear unwanted and dysfunctional cellular cargoes, which are sequestered in autophagosomes before their delivery to lysosomes for degradation. Autophagy cargo selection, mediated by cargo receptors, varies across cell types and conditions. Understanding the cargo features is essential for elucidating autophagy's function in specific physiological or pathological contexts. Here, we present a simple and rapid method for isolating LC3B-positive autophagosomes from the tissues of GFP-LC3 transgenic mice, a widely used autophagy reporter model, without relying on the complex ultracentrifugation steps required by traditional methods. When combined with quantitative proteomics, this approach enables efficient in vivo …

Novel Pencil-Beam Scanning Proton Lattice Radiation Therapy For The Treatment Of Bulky Liver Cancer: Dosimetric Comparison With Vmat-Lattice Radiotherapy, Yuting Li, Rachael M Martin-Paulpeter, Christine V Chung, Miguel A Aguilar, Carlos A Matias, Adrian Delgado, Saurabh S Nair, Laurence E Court, Luis Perles, Narayan Sahoo, Ronald X Zhu, Falk Poenisch, David B Flint, Gabriel O Sawakuchi, Sam Beddar, Eugene Koay, Jamie S Baker, Ethan B Ludmir, Joshua S Niedzielski

Faculty, Staff and Student Publications

Background: Spatially fractionated radiotherapy (SFRT) delivered as lattice radiotherapy (LRT) creates high-dose 'vertex' subvolumes (VTVH) embedded within low-dose 'valley' regions (VTVL) to intensify intratumoral dose while minimizing radiation dose and toxicity to organs at risk (OARs). We developed a pencil-beam scanning (PBS) intensity modulated proton therapy (IMPT) LRT planning approach and dosimetrically compared it directly with contemporary photon-based volume modulated arc therapy (VMAT) LRT for liver cancer with bulky tumors.

Methods: Twenty-one retrospective liver cases were replanned in RayStation to a single fraction of 20 Gy to VTVH with explicit VTVL sparing (mean dose < 5Gy). Primary dosimetric endpoints were VTVH D80 and VTVL mean dose (analogous to mean valley dose), with secondary endpoints of VTVH/VTVL ratios (PVDR-like metrics at D80/D90/D100), VTVL D5/D80, GTV D10/D90, and planning risk volume (PRV) 0.03 cm³ hotspots. Statistical analysis consisted of paired tests (t-test or Wilcoxon signed-rank) after assessing data normality (Shapiro-Wilk tests) and using α=0.05 for significance.

Results: Compared with photon VMAT-LRT, IMPT-LRT …

Disulfidptosis And Its Emerging Relevance In Cancer And Immunity, Qidong Li, Shengrong Wu, Li Zhuang, Boyi Gan

Faculty, Staff and Student Publications

Disulfidptosis is a recently identified form of regulated cell death (RCD) triggered by disulfide stress when cystine uptake via solute carrier family 7 member 1 (SLC7A11) overwhelms the cell's reducing capacity. Unlike apoptosis or other "cell suicide" pathways, disulfidptosis likely represents a "cell sabotage" mechanism, defined by aberrant disulfide bonding and catastrophic actin cytoskeleton collapse. In this Perspective, we examine the paradoxical role of SLC7A11 as both a ferroptosis protector and a disulfidptosis trigger, and the mechanistic hallmarks of disulfidptosis. We highlight emerging therapeutic strategies to target disulfidptosis in cancer, including glucose transporter inhibition, redox-targeting agents, and nanomaterial-based approaches, and …

E2f1 Overexpression Reduces Aging-Associated Dna Damage In Cultured Cerebral Endothelial Cells And Improves Cognitive Performance In Aged Mice, Sheelu Monga, Samantha Flores, Maria Pilar Blasco-Conesa, Syed M Rahman, Brian Noh, Pedram Peesh, Bhanu Priya Ganesh, Sean P Marrelli, Louise D Mccullough, Jose Felix Moruno-Manchon

Faculty, Staff and Student Publications

As we age, cerebral endothelial cells (CECs) are less efficient in maintaining genome integrity and accumulate DNA damage. DNA damage in the brain endothelium can lead to the impairment of the blood–brain barrier (BBB), which is a major factor in brain dysfunction and dementia. Thus, identifying factors that regulate DNA repair in the brain endothelium can prevent brain dysfunction associated with aging. E2F1 is a transcription factor that regulates the expression of genes associated with DNA repair, among other functions. We hypothesize that E2F1 is downregulated in the brain vasculature of mice with aging and that E2F1 upregulation can improve …

A Novel Automated Ct Biomarker To Predict Outcomes In Acute Ischemic Stroke: Net Water Uptake, Monica Mallavarapu, Hyun Woo Kim, Ananya Iyyangar, Sergio Salazar-Marioni, Albert J Yoo, Luca Giancardo, Sunil A Sheth, Jerome A Jeevarajan

Faculty, Staff and Student Publications

Background: Recent trials of large core thrombectomy have shown that our traditional understanding of infarct characteristics and reperfusion benefit may be incomplete for patients with acute ischemic stroke (AIS). The Alberta Stroke Program Early CT Score (ASPECTS) has wide inter-rater variability, and modern studies have also shown that reperfusion therapies can benefit some patients regardless of the ASPECTS. Reproducible imaging metrics that account for the degree of hypo-attenuation on non-contrast computed tomography (NCCT) may be better suited to guide treatments. Here, we evaluate Net Water Uptake (NWU), a novel NCCT metric that can be calculated in a rapid and automated …

Introduction: An estimated 20% of women consume alcohol during pregnancy, and 10% of women receive antidepressants during their pregnancy. Women with depression are more likely to use alcohol (EtOH) in early pregnancy and are more likely to have a child with one of the fetal alcohol spectrum disorders (FASD). Previously, we provided evidence in rat neurons in vitro that DING phosphatase (p38SJ, a member of the DINGGG family of proteins that has neuroprotective effects under conditions of cellular stress) was neuroprotective against EtOH-mediated toxicity. Now, we examine the effects of DING, alone or in combination with EtOH and serotonergic (5-HT) …

The Deceleration Dilemma: Leveraging The Relationship Between Quadriceps Function And Deceleration To Optimize Return To Sport, Steven Higbie, Christopher Gallina, Russ Paine, Lane Bailey, Walter R Lowe

Faculty, Staff and Student Publications

Decelerations frequently occur during sport and are often associated with non-contact knee injury mechanisms. Though decelerations place a high eccentric demand on the quadriceps, little is known about the relationship between quadriceps function and deceleration performance. Traditional functional testing batteries often over-estimate quadriceps function and lack assessments of deceleration performance, while current deceleration testing is often heavily reliant on technology and performed at shallow angles. The purpose of this clinical commentary is to describe the relationship between deceleration and quadriceps function, suggest two clinical tests to assess deceleration performance, and provide exercise suggestions for improving deceleration performance. The authors believe …
