Ferroptosis has been recognized as a unique cell death modality driven by excessive lipid peroxidation and unbalanced cellular metabolism. In this study, we established a protein interaction landscape for ferroptosis pathways through proteomic analyses, and identified choline/ethanolamine phosphotransferase 1 (CEPT1) as a lysophosphatidylcholine acyltransferase 3 (LPCAT3)-interacting protein that regulates LPCAT3 protein stability. In contrast to its known role in promoting phospholipid synthesis, we showed that CEPT1 suppresses ferroptosis potentially by interacting with phospholipases and breaking down certain pro-ferroptotic polyunsaturated fatty acid (PUFA)-containing phospholipids. Together, our study reveals a previously unrecognized role of CEPT1 in suppressing ferroptosis.

Carcinomas are associated with metastasis to specific organs while sparing others. Breast cancer presents with lung metastasis but rarely kidney metastasis. Using this difference as an example, we queried the mechanism(s) behind the proclivity for organ-specific metastasis. We used spontaneous and implant models of metastatic mammary carcinoma coupled with inflammatory tissue fibrosis, single-cell sequencing analyses and functional studies to unravel the causal determinants of organ-specific metastasis. Here we show that lung metastasis is facilitated by angiopoietin 2 (Ang2)-mediated suppression of lung-specific endothelial tight junction protein Claudin 5, which is augmented by the inflammatory fibrotic microenvironment and prevented by anti-Ang2 blocking …

Decoding The Molecular Symphony: Interactions Between The M6a And P53 Signaling Pathways In Cancer, Rachel Shoemaker, Mo-Fan Huang, Ying-Si Wu, Cheng-Shuo Huang, Dung-Fang Lee

Faculty, Staff and Student Publications

The p53 tumor suppressor gene governs a multitude of complex cellular processes that are essential for anti-cancer function and whose dysregulation leads to aberrant gene transcription, activation of oncogenic signaling and cancer development. Although mutations can occur at any point in the genetic sequence, missense mutations comprise the majority of observed p53 mutations in cancers regardless of whether the mutation is germline or somatic. One biological process involved in both mutant and wild-type p53 signaling is the N6-methyladenosine (m6A) epitranscriptomic network, a type of post-transcriptional modification involved in over half of all eukaryotic mRNAs. Recently, a significant number of …

Patient-specific tissue geometries were assigned from pre-delivery MRIs. Model parameters were personalized with either 1) individual-based calibration with longitudinal SPECT images, or 2) population-based assignment via leave-one-out cross-validation. The concordance correlation coefficient …

Increasing Power In Phase Iii Oncology Trials With Multivariable Regression: An Empirical Assessment Of 535 Primary End Point Analyses, Alexander D Sherry, Adina H Passy, Zachary R Mccaw, Joseph Abi Jaoude, Timothy A Lin, Ramez Kouzy, Avital M Miller, Gabrielle S Kupferman, Esther J Beck, Pavlos Msaouel, Ethan B Ludmir

Faculty, Staff and Student Publications

Purpose: A previous study demonstrated that power against the (unobserved) true effect for the primary end point (PEP) of most phase III oncology trials is low, suggesting an increased risk of false-negative findings in the field of late-phase oncology. Fitting models with prognostic covariates is a potential solution to improve power; however, the extent to which trials leverage this approach, and its impact on trial interpretation at scale, is unknown. To that end, we hypothesized that phase III trials using multivariable PEP analyses are more likely to demonstrate superiority versus trials with univariable analyses.

Methods: PEP analyses were reviewed from …

Nevertheless, most patients inevitably confront the challenge of drug resistance. This phenomenon arises not solely from intrinsic alterations within cancer cells but also from the intricate dynamics of the tumor microenvironment and the complex interactions that occur between cancer cells and their immediate surroundings. This review consolidates the current knowledge regarding EGFR-TKI resistance mechanisms, with a specific emphasis on unraveling the …

Nanoscale Gold Nanoparticle (Gnp)-Laden Tumor Cell Model And Its Use For Estimation Of Intracellular Dose From Gnp-Induced Secondary Electrons, Sandun Jayarathna, Amrit Kaphle, Sunil Krishnan, Sang Hyun Cho

Faculty, Staff and Student Publications

Background: Gold nanoparticles (GNPs) accumulated within tumor cells have been shown to sensitize tumors to radiotherapy. From a physics point of view, the observed GNP-mediated radiosensitization is due to various downstream effects of the secondary electron (SE) production from internalized GNPs such as GNP-mediated dose enhancement. Over the years, numerous computational investigations on GNP-mediated dose enhancement/radiosensitization have been conducted. However, such investigations have relied mostly on simple cellular geometry models and/or artificial GNP distributions. Thus, it is at least desirable, if not necessary, to conduct further investigations using cellular geometry models that properly reflect realistic cell morphology as well as …

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 …

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 …

Consequences Of Local Conspecific Density Effects For Plant Diversity And Community Dynamics, Joseph A. Lamanna, Stefan A. Schnitzer

Biological Sciences Faculty Research and Publications

Conspecific density dependence (CDD) in plant populations is widespread, most likely caused by local-scale biotic interactions, and has potentially important implications for biodiversity, community composition, and ecosystem processes. However, progress in this important area of ecology has been hindered by differing viewpoints on CDD across subfields in ecology, lack of synthesis across CDD-related frameworks, and misunderstandings about how empirical measurements of local CDD fit within the context of broader ecological theories on community assembly and diversity maintenance. Here, we propose a conceptual synthesis of local-scale CDD and its causes, including species-specific antagonistic and mutualistic interactions. First, we compare and clarify …

For as long as there has been work, there has been a “future of work,” through humans’ ingenuity and drive to get things done easier, faster, and better. With the industrial revolution, efforts to shape a better future of work were dominated by improvements in machinery that soon led to fears that these machines might take away jobs from workers, enriching the rich and leaving the poor poorer (Allen, 2017). Later, John Maynard Keynes (1930) optimistically predicted technological unemployment (a net loss of jobs due to shifts in the nature of work outpacing the economy’s ability to redeploy talent) would …
