The Efficacy-Associated Biomarkers For Immune Checkpoint Inhibitors In Gastrointestinal Cancer: A Literature Review, Jessie Lee, Yifei Shan, Angelique Wong, Elizabeth A Brown, Mitchell Callahan, Robert A Hernandez, Michael J Mienaltowski

Faculty, Staff and Student Publications

White striping (WS) is a common myopathy seen in fast-growing broilers. Studies have demonstrated that chitosan is effective as an antioxidant and has antiobesity and fat-absorption reduction properties. We hypothesized that the dietary supplementation of chitosan would have similar effects when fed to fast-growing broilers and would thus lower WS incidence and improve meat quality. One hundred twenty-six broilers were fed corn-soy diets. The grower and finisher diets contained either 0, 0.2, or 0.4% chitosan. After a 6 wk growth period, birds were euthanized, and then WS and gross pathology scores were assessed. Pectoralis major tissues were collected to evaluate …

Case Sampling For Evaluating Hospital Postoperative Morbidity In Us Surgical Quality Improvement Programs, Vivi W Chen, Tracey Rosen, Yongquan Dong, Peter A Richardson, Jennifer R Kramer, Laura A Petersen, Nader N Massarweh

Center for Medical Ethics and Health Policy Staff Publications

Importance: US surgical quality improvement (QI) programs use data from a systematic sample of surgical cases, rather than universal review of all cases, to assess and compare risk-adjusted hospital postoperative complication rates. Given decreasing postoperative complication rates over time and the types of cases eligible for abstraction, it is unclear whether case sampling is robust for identifying hospitals with higher than expected complications.

Objective: To compare the assessment of hospital 30-day complication rates derived from sampling strategy used by some US surgical QI programs relative to universal review of all cases.

Design, setting, and participants: This US hospital-level analysis took …

Cub Domains Are Not Required For Ovch2 Function In Sperm Maturation In The Mouse Epididymis, Katarzyna Kent, Kaori Nozawa, Courtney Sutton, Frey Daniel, Masahito Ikawa, Thomas X Garcia, Martin M Matzuk

Faculty, Staff and Students Publications

BACKGROUND: Ovochymase 2 (Ovch2) is an epididymis-specific gene that is required for male fertility. While a multitude of reproductive tract-specific genes required for male fertility have been identified, OVCH2 is thus far the first protein required for male fertility that contains Complement C1r/C1s, Uegf, Bmp1 (CUB) domains located in tandem in the C-terminus of the protein. Identifying the functional significance of this unique domain has implications in better understanding fertility and infertility and as a potential contraceptive target.

OBJECTIVE: The goals of these studies were to understand the influence and requirement of OVCH2 CUB domains in the localization and functional …

Targeting Glutamine Dependence With Drp-104 Inhibits Proliferation And Tumor Growth Of Castration-Resistant Prostate Cancer, David Moon, J Spencer Hauck, Xue Jiang, Holly Quang, Lingfan Xu, Fan Zhang, Xia Gao, Robert Wild, Jeffrey I Everitt, Everardo Macias, Yiping He, Jiaoti Huang

Faculty, Staff and Students Publications

BACKGROUND: Prostate cancer (PCa) continues to be one of the leading causes of cancer deaths in men. While androgen deprivation therapy is initially effective, castration-resistant PCa (CRPC) often recurs and has limited treatment options. Our previous study identified glutamine metabolism to be critical for CRPC growth. The glutamine antagonist 6-diazo-5-oxo-l-norleucine (DON) blocks both carbon and nitrogen pathways but has dose-limiting toxicity. The prodrug DRP-104 is expected to be preferentially converted to DON in tumor cells to inhibit glutamine utilization with minimal toxicity. However, CRPC cells' susceptibility to DRP-104 remains unclear.

METHODS: Human PCa cell lines (LNCaP, LAPC4, C4-2/MDVR, PC-3, 22RV1, …

Retrograde Endocannabinoid Signaling At Inhibitory Synapses In Vivo, Barna Dudok, Linlin Z Fan, Jordan S Farrell, Shreya Malhotra, Jesslyn Homidan, Doo Kyung Kim, Celestine Wenardy, Charu Ramakrishnan, Yulong Li, Karl Deisseroth, Ivan Soltesz

Faculty, Staff and Students Publications

Endocannabinoid (eCB)-mediated suppression of inhibitory synapses has been hypothesized, but this has not yet been demonstrated to occur in vivo because of the difficulty in tracking eCB dynamics and synaptic plasticity during behavior. In mice navigating a linear track, we observed location-specific eCB signaling in hippocampal CA1 place cells, and this was detected both in the postsynaptic membrane and the presynaptic inhibitory axons. All-optical in vivo investigation of synaptic responses revealed that postsynaptic depolarization was followed by a suppression of inhibitory synaptic potentials. Furthermore, interneuron-specific cannabinoid receptor deletion altered place cell tuning. Therefore, rapid, postsynaptic, activity-dependent eCB signaling modulates inhibitory …

GrimAge acceleration has previously predicted age-related morbidities and mortality. In the current study, we sought to examine how GrimAge is associated with genetic predisposition for systemic inflammation and whether psychosocial factors moderate this association. Military veterans from the National Health and Resilience in Veterans study, which surveyed a nationally representative sample of European American male veterans, provided saliva samples for genotyping (N = 1135). We derived polygenic risk scores (PRS) from the UK Biobank as markers of genetic predisposition to inflammation. Results revealed that PRS for three inflammatory PRS markers—HDL (lower), apolipoprotein B (lower), and gamma-glutamyl transferase (higher)—were associated …

Faculty, Staff and Students Publications

Objective: Liver transplantation (LTx) is an intervention when medical management is not sufficiently preventing individuals with urea cycle disorders (UCDs) from the occurrence of hyperammonemic events. Supplementation with L-citrulline/arginine is regularly performed prior to LTx to support ureagenesis and is often continued after the intervention. However, systematic studies assessing the impact of long-term L-citrulline/arginine supplementation in individuals who have undergone LTx is lacking to date.

Methods: Using longitudinal data collected systematically, a comparative analysis was carried out by studying the effects of long-term L-citrulline/arginine supplementation vs. no supplementation on health-related outcome parameters (i.e., anthropometric, neurological, and cognitive outcomes) in individuals …

Stat5 Induces Androgen Receptor (Ar) Gene Transcription In Prostate Cancer And Offers A Druggable Pathway To Target Ar Signaling, Cristina Maranto, Lavannya Sabharwal, Vindhya Udhane, Samuel P. Pitzen, Braedan Mccluskey, Songyan Qi, Christine O'Connor, Savita Devi, Scott Johnson, Kenneth Jacobsohn, Anjishnu Banerjee, Kenneth A. Iczkowski, Liang Wang, Scott M. Dehm, Marja T. Nevalainen

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Androgen receptor (AR) drives prostate cancer (PC) growth and progression, and targeting AR signaling is the mainstay of pharmacological therapies for PC. Resistance develops relatively fast as a result of refueled AR activity. A major gap in the field is the lack of understanding of targetable mechanisms that induce persistent AR expression in castrate-resistant PC (CRPC). This study uncovers an unexpected function of active Stat5 signaling, a known promoter of PC growth and clinical progression, as a potent inducer of AR gene transcription. Stat5 suppression inhibited AR gene transcription in preclinical PC models and reduced the levels of wild-type, mutated, …

SDB PC1, characterized by frequent respiratory events common in older and male adults, is …
