Metabolic Cell Death In Cancer: Ferroptosis, Cuproptosis, Disulfidptosis, And Beyond, Chao Mao, Min Wang, Li Zhuang, Boyi Gan

Faculty, Staff and Student Publications

Cell death resistance represents a hallmark of cancer. Recent studies have identified metabolic cell death as unique forms of regulated cell death resulting from an imbalance in the cellular metabolism. This review discusses the mechanisms of metabolic cell death-ferroptosis, cuproptosis, disulfidptosis, lysozincrosis, and alkaliptosis-and explores their potential in cancer therapy. Our review underscores the complexity of the metabolic cell death pathways and offers insights into innovative therapeutic avenues for cancer treatment.

Improving The Palliative-Procedure Decision-Making Process For Patients With Peritoneal Carcinomatosis: A Secondary Analysis, Jaclyn A Wall, Rachel A Pozzar, Andrea C Enzinger, Anna Tavormina, Catherine Howard, Ursula A Matulonis, Joyce F Liu, Neil Horowitz, Larissa A Meyer, Alexi A Wright

Faculty, Staff and Student Publications

Background: Peritoneal carcinomatosis (PC) is common in patients with advanced gynecologic and gastrointestinal cancers. Frequently, patients with PC undergo palliative surgery or procedures to manage disease-related complications and side effects. However, there are limited data regarding patients' and family caregivers' decision-making processes about these procedures. Thus, we sought to describe the decision-making experiences of patients with PC who elect to pursue palliative surgical procedures and their family caregivers.

Methods: We conducted a secondary analysis of qualitative data collected during a pilot randomized controlled trial of BOLSTER, a nurse-led telehealth intervention for patients with PC and their caregivers after an acute …

Understanding, Diagnosing, And Treating Pancreatic Cancer From The Perspective Of Telomeres And Telomerase, Songting Shou, Yuanliang Li, Jiaqin Chen, Xing Zhang, Chuanlong Zhang, Xiaochen Jiang, Fudong Liu, Li Yi, Xiyuan Zhang, En Geer, Zhenqing Pu, Bo Pang

Faculty, Staff and Student Publications

Telomerase is associated with cellular aging, and its presence limits cellular lifespan. Telomerase by preventing telomere shortening can extend the number of cell divisions for cancer cells. In adult pancreatic cells, telomeres gradually shorten, while in precancerous lesions of cancer, telomeres in cells are usually significantly shortened. At this time, telomerase is still in an inactive state, and it is not until before and after the onset of cancer that telomerase is reactivated, causing cancer cells to proliferate. Methylation of the telomerase reverse transcriptase (TERT) promoter and regulation of telomerase by lactate dehydrogenase B (LDHB) is the mechanism of telomerase …

Smyd5 Is A Ribosomal Methyltransferase That Catalyzes Rpl40 Lysine Methylation To Enhance Translation Output And Promote Hepatocellular Carcinoma, Bisi Miao, Ling Ge, Chenxi He, Xinghao Wang, Jibo Wu, Xiang Li, Kun Chen, Jinkai Wan, Shenghui Xing, Lingnan Ren, Zhennan Shi, Shengnan Liu, Yajun Hu, Jiajia Chen, Yanyan Yu, Lijian Feng, Natasha M Flores, Zhihui Liang, Xinyi Xu, Ruoxin Wang, Jian Zhou, Jia Fan, Bin Xiang, En Li, Yuanhui Mao, Jingdong Cheng, Kehao Zhao, Pawel K Mazur, Jiabin Cai, Fei Lan

While lysine methylation is well-known for regulating gene expression transcriptionally, its implications in translation have been largely uncharted. Trimethylation at lysine 22 (K22me3) on RPL40, a core ribosomal protein located in the GTPase activation center, was first reported 27 years ago. Yet, its methyltransferase and role in translation remain unexplored. Here, we report that SMYD5 has robust in vitro activity toward RPL40 K22 and primarily catalyzes RPL40 K22me3 in cells. The loss of SMYD5 and RPL40 K22me3 leads to reduced translation output and disturbed elongation as evidenced by increased ribosome collisions. SMYD5 and RPL40 K22me3 are upregulated in hepatocellular carcinoma …

Calcium Rescues Streptococcus Pneumoniae D39 Δmnte Manganese-Sensitive Growth Phenotype, Reuben Opoku, Edgar Carrasco, Nicholas R De Lay, Julia E Martin

Faculty, Staff and Student Publications

Calcium (Ca2+) functions as a universal signal messenger in eukaryotes but in bacteria, the physiological roles for Ca2+ are limited. Here, we examine the role of Ca2+ in Streptococcus pneumoniae during manganese (Mn2+) intoxication. S. pneumoniae mntE mutants, lacking the Mn2+ efflux transporter, exhibit impaired growth due to accumulation of Mn2+ when exposed to elevated exogenous Mn2+. This Mn2+-sensitive growth defect is restored to wild-type growth level by exogenous Ca2+, in a Ca2+-dependent manner. Despite growth restoration of the mntE mutant to wild-type levels, cellular Mn2+ remains elevated in this strain. Bacterial capsule production is also increased for the mntE …

Beneficial Effects Of Lactobacillus Plantarum On Growth Performance, Immune Status, Antioxidant Function And Intestinal Microbiota In Broilers, Xiao Xiao, Tiantian Cui, Songke Qin, Tao Wang, Jinsong Liu, Lihan Sa, Yanping Wu, Yifan Zhong, Caimei Yang

Faculty, Staff and Student Publications

Lactobacillus plantarum (L. plantarum) has been globally regarded as antibiotic alternative in animal farming in the past few years. However, the potential function of L. plantarum in broilers has not been systemically explored. In this study, a total of 560 one-day-old yellow-feathered broilers were randomly divided into 3 groups, fed with basal diet and drank with L. plantarum HJZW08 (LP) at the concentration of 0 (CON), 1000 × 10^5 (LP1000), and 2000 × 10^5 CFU/L (LP2000) for 70 d.

Faculty, Staff and Student Publications

Objective: Patients with advanced gynecologic (GYN) and gastrointestinal (GI) cancers frequently develop peritoneal carcinomatosis (PC), which limits prognosis and diminishes health-related quality of life (HRQoL). Palliative procedures may improve PC symptoms, yet patients and caregivers report feeling unprepared to manage ostomies, catheters, and other complex needs. Our objectives were to (1) assess the feasibility of an efficacy trial of a nurse-led telehealth intervention (BOLSTER) for patients with PC and their caregivers; and (2) assess BOLSTER's acceptability, potential to improve patients' HRQoL and self-efficacy, and potential impact on advance care planning (ACP).

Methods: Pilot feasibility RCT. Recently hospitalized adults with advanced …

Feeding behaviour is influenced by two primary factors: homoeostatic needs driven by hunger and hedonic desires for pleasure even in the absence of hunger. While efficient homoeostatic feeding is vital for survival, excessive hedonic feeding can lead to adverse consequences such as obesity and metabolic dysregulations. However, the neurobiological mechanisms that orchestrate homoeostatic versus hedonic food consumption remain largely unknown. Here we show that GABAergic proenkephalin (Penk) neurons in the diagonal band of Broca (DBB) of male mice respond to food presentation. We further demonstrate that a subset of DBBPenk neurons that project to the paraventricular nucleus of the hypothalamus …

Tuberculosis Prevention: Current Strategies And Future Directions, Anca Vasiliu, Leonardo Martinez, Rishi K Gupta, Yohhei Hamada, Tara Ness, Alexander Kay, Maryline Bonnet, Martina Sester, Stefan H E Kaufmann, Christoph Lange, Anna M Mandalakas

Faculty, Staff and Students Publications

BACKGROUND: An estimated one fourth of the world's population is infected with Mycobacterium tuberculosis, and 5-10% of those infected develop tuberculosis in their lifetime. Preventing tuberculosis is one of the most underutilized but essential components of curtailing the tuberculosis epidemic. Moreover, current evidence illustrates that tuberculosis manifestations occur along a dynamic spectrum from infection to disease rather than a binary state as historically conceptualized. Elucidating determinants of transition between these states is crucial to decreasing the tuberculosis burden and reaching the END-TB Strategy goals as defined by the WHO. Vaccination, detection of infection, and provision of preventive treatment are key …

Disruption Of Fuz In Mouse Embryos Generates Hypoplastic Hindbrain Development And Reduced Cranial Nerve Ganglia, Carlo Donato Caiaffa, Yogeshwari S Ambekar, Manmohan Singh, Ying Linda Lin, Bogdan Wlodarczyk, Salavat R Aglyamov, Giuliano Scarcelli, Kirill V Larin, Richard H Finnell

Faculty, Staff and Students Publications

Background: The brain and spinal cord formation is initiated in the earliest stages of mammalian pregnancy in a highly organized process known as neurulation. Environmental or genetic interferences can impair neurulation, resulting in clinically significant birth defects known collectively as neural tube defects. The Fuz gene encodes a subunit of the CPLANE complex, a macromolecular planar polarity effector required for ciliogenesis. Ablation of Fuz in mouse embryos results in exencephaly and spina bifida, including dysmorphic craniofacial structures due to defective cilia formation and impaired Sonic Hedgehog signaling.

Results: We demonstrate that knocking Fuz out during embryonic mouse development results in …

Potentially Functional Variants Of Chmp4a And Panx1 In The Pyroptosis-Related Pathway Predict Survival Of Patients With Non-Oropharyngeal Head And Neck Squamous Cell Carcinoma, Xiaozhun Tang, Huiling Wang, Hongliang Liu, Guojun Li, Erich M Sturgis, Sanjay Shete, Qingyi Wei

Faculty, Staff and Students Publications

Background: Pyroptosis has been implicated in the advancement of various cancers. Triggering pyroptosis within tumors amplifies the immune response, thereby fostering an antitumor immune environment. Nonetheless, few published studies have evaluated associations between functional variants in the pyroptosis-related genes and clinical outcomes of patients with non-oropharyngeal head and neck squamous cell carcinoma (NON-ORO HNSCC).

Methods: We conducted an association study of 985 NON-ORO HNSCC patients who were randomly divided into two groups: the discovery group of 492 patients and the replication group of 493 patients. We used Cox proportional hazards regression analysis to examine associations between genetic variants of the …

Contributions Of White Adipose Tissue To Energy Requirements For Female Reproduction, Elizabeth S Anaya, Evelyn L De Groot, John P Lydon, Stephanie A Pangas, Sean M Hartig

Faculty, Staff and Students Publications

Body composition impacts female fertility and there are established relationships between adipose tissue and the reproductive system. Maintaining functional adipose tissue is vital for meeting the energetic demands during the reproductive process, from ovulation to delivery and lactation. White adipose tissue (WAT) shows plastic responses to daily physiology and secretes diverse adipokines that affect the hypothalamic-pituitary-ovarian axis, but many other interorgan interactions remain to be determined. This review summarizes the current state of research on the dialogue between WAT and the female reproductive system, focusing on the impact of this crosstalk on ovarian and endometrial factors essential for fecundity.

Objective: We aimed to determine the incidence of growth failure in infants with necrotizing enterocolitis (NEC) or spontaneous intestinal perforation (SIP) and whether initial laparotomy versus peritoneal drainage (PD) impacted the likelihood of growth failure.

Summary background data: Infants with surgical NEC and SIP have high mortality, and most have neurodevelopmental impairment and poor growth. Existing literature on growth outcomes for these infants is limited.

Methods: This is a preplanned secondary study of the Necrotizing Enterocolitis Surgery Trial dataset. The primary outcome was growth failure (Z-score for weight < -2.0) at 18 to 22 months. We used logistic regression, including diagnosis and treatment, as covariates. Secondary outcomes were analyzed using the Fisher exact or Pearson χ2 test for categorical variables and the Wilcoxon rank sum test or one-way ANOVA for continuous variables.

Results: Among 217 survivors, 207 infants (95%) had primary outcome data. Growth …

Bioengineering Of Intestinal Grafts, Madushani Herath, Allison L Speer

Faculty, Staff and Student Publications

Intestinal failure manifests as an impaired capacity of the intestine to sufficiently absorb vital nutrients and electrolytes essential for growth and well-being in pediatric and adult populations. Although parenteral nutrition remains the mainstay therapeutic approach, the pursuit of a definitive and curative strategy, such as regenerative medicine, is imperative. Substantial advancements in the field of engineered intestinal tissues present a promising avenue for addressing intestinal failure; nevertheless, extensive research is still necessary for effective translation from experimental benchwork to clinical bedside applications.

Leveraging The Science Of Early Life Predictability To Inform Policies Promoting Child Health, Laura M. Glynn, Sabrina R. Liu, Candice Taylor Lucas, Elysia Poggi Davis

Psychology Faculty Articles and Research

Addressing the tremendous burden of early-life adversity requires constructive dialogues between scientists and policy makers to improve population health. Whereas dialogues focused on several aspects of early-life adversity have been initiated, discussion of an underrecognized form of adversity that has been observed across multiple contexts and cultures is only now emerging. Here we provide evidence for “why unpredictability?”, including: 1. Evidence that exposures to unpredictability affect child neurodevelopment, with influences that persist into adulthood. 2. The existence of a translational non-human animal model of exposure to early life unpredictability that can be capitalized upon to causally probe neurobiological mechanisms. 3. …

BioMedicine

Background: Dahlia (Dahlia variabilis), a widely cultivated ornamental plant in Indonesia, is known to contain 84.08% inulin in its tubers. Numerous studies have demonstrated the antidiabetic potential of inulin from various plant sources. However, most of the research is in the form of a mixture of inulin with other active substances, and no one has analyzed the effects of inulin derived from dahlia tubers. This study examines the effect of inulin from dahlia tuber extract on blood glucose levels, serum insulin expression, pancreatic tissue insulin expression, homeostatic model assessment of insulin resistance (HOMA-IR), and the extent of …

Polyphenols In Bee Products And Prevention Of Cell Senescence, Siti Nuriah Mohd Noor, Marahaini Musa, Ahmad Azlina, Siew Hua Gan, Kannan Thirumulu Ponnuraj

BioMedicine

Sustaining the continuity of cells and their homeostasis throughout the lifespan is compulsory for the survival of an organism. Cellular senescence is one of mechanisms involved in cell homeostasis and survival, and plays both important and detrimental roles in the maintenance of malfunctioned and normal cells. However, when exposed to various insults (genetic, metabolic and environmental), the cells undergo oxidative stress which may induce premature senescence, or so-called stress-induced premature senescence. Many age-related diseases are associated with premature senescence. Hence, there is growing interest in the intake of natural sources such as dietary food, which has protective functions on human …

Mechanisms And Metabolic Consequences Of Adipocyte Progenitor Replicative Senescence, Tonghui Lin, Aftab Mohammad, Mikhail G Kolonin, Kristin L Eckel-Mahan

Faculty, Staff and Student Publications

In recent decades, obesity has become a worldwide epidemic. As a result, the importance of adipose tissue (AT) as a metabolically active storage depot for lipids and a key mediator of body-wide metabolism and energy balance has been increasingly recognized. Emerging from the studies of AT in metabolic disease is a recognition of the importance of the adipocyte progenitor cell (APC) population of AT being the gatekeeper of adipocyte function. APCs have the capability to self-renew and undergo adipogenesis to propagate new adipocytes capable of lipid storage, which is important for maintaining a healthy fat pad, devoid of dysfunctional lipid …

Natural Killer Cell Effector Function Is Critical For Host Defense Against Alcohol-Associated Bacterial Pneumonia, Daniel Villageliu, Kelly C. Cunningham, Deandra R. Smith, Daren L. Knoell, Mason Mandolfo, Todd A. Wyatt, Derrick R. Samuelson

Food for Health: Publications

Alcohol use is an independent risk factor for the development of bacterial pneumonia due, in part, to impaired mucus-facilitated clearance, macrophage phagocytosis, and recruitment of neutrophils. Alcohol consumption is also known to reduce peripheral natural killer (NK) cell numbers and compromise NK cell cytolytic activity, especially NK cells with a mature phenotype. However, the role of innate lymphocytes, such as NK cells during host defense against alcohol-associated bacterial pneumonia is essentially unknown. We have previously shown that indole supplementation mitigates increases in pulmonary bacterial burden and improves pulmonary NK cell recruitment in alcohol-fed mice, which were dependent on aryl hydrocarbon …

Faculty, Staff and Students Publications

Although long-term survival in Rett syndrome (RTT) has been observed, limited information on older people with RTT exists. We hypothesized that increased longevity in RTT would be associated with genetic variants in MECP2 associated with milder severity, and that clinical features would not be static in older individuals. To address these hypotheses, we compared the distribution of MECP2 variants and clinical severity between younger individuals with Classic RTT (under 30 years old) and older individuals (over 30 years old). Contrary to expectation, enrichment of a severe MECP2 variant (R106W) was observed in the older cohort. Overall severity was not different …
