Decoding Metastatic Microenvironments Through Single-Cell Omics Reveals New Insights Into Niche Dynamics And Tumor Evolution, Fengshuo Liu, Xiang H-F Zhang

Faculty, Staff and Students Publications

Metastasis is the predominant cause of cancer mortality, primarily driven by complex tumor-host interactions within specialized metastatic niches. Recent advances in single-cell technologies have provided unprecedented insights into metastatic niche formation, evolution and function, including how primary tumors precondition distant organs for metastases and how disseminated tumor cells dynamically interact with host cells to modulate their environments. Integrated single-cell studies across multiple cancer types have also revealed divergent and convergent metastatic adaptation strategies. These findings collectively highlight metastasis as a dynamic, cooperative process shaped by intricate tumor-host interactions, and provide a foundation for novel therapeutic strategies targeting components of the …

Purpose: There is evidence that statins might improve the outcome of patients with breast cancer. The role of statins in patients with early HER2-positive breast cancer is unknown. Therefore, we explored the association between statin use and survival outcomes in early HER2-positive breast cancer patients in the phase III APHINITY trial (adjuvant pertuzumab/trastuzumab).

Methods: All patients (intent-to-treat population, n = 4804) were included (6.2 years median follow-up database). The primary objective was to investigate the association of statin use on invasive disease-free survival (IDFS), distant relapse-free interval (DRFI), and overall survival (OS). Patients who received statins at baseline, or started …

Deficits In Mitochondrial Dynamics And Iron Balance Result In Templated Insertions, Jordan Fox, Yang Yu, Yang Yu, Pilendra Thakre, Chloe Fox, Qian Li, Yunxia Wang, Adam Hughes, Xin Wang, Kaifu Chen, Grzegorz Ira

Faculty, Staff and Students Publications

Mitochondrial membrane dynamics control the shape, number, and distribution of mitochondria and regulate energy production and cell health. In a screen for yeast mutants with increased levels of templated insertions (~10-1000 bp) in the nuclear genome, we identified mitochondrial fusion deficient mutants (mgm1Δ, ugo1Δ, fzo1Δ). We found that fusion mutants activate the iron regulon, have decreased iron-sulfur clusters (ISCs), and increased DNA damage, suggesting a role of iron homeostasis in preventing insertions. Consistently, a secondary screen found mutants affecting iron-sulfur cluster production (yfh1Δ, grx5Δ), vacuolar iron storage (ccc1Δ) or general iron homeostasis (aft1Δ) to exhibit high insertion levels. Treatment with …

A Hypomorphic Model Of Cps1 Deficiency For Investigating The Effects Of Hyperammonemia On The Developing Nervous System, Stuti Bakshi, Taryn Diep, Brandon J Willis, Rachel Reyes, Grace F Wu, Georgios Makris, Martin Poms, Isabel Day, Qin Sun, Irina Zhuravka, Lindsay Lueptow, Michelle Tang, Gareth A Cromie, Aimée M Dudley, Johannes Häberle, Gerald S Lipshutz

Carbamoyl phosphate synthetase 1 (CPS1) deficiency is a rare metabolic disorder that, in neonatal onset, is typically characterized by severe life-threatening and neurologically injuring hyperammonemic episodes with high unmet patient need. Patients that retain limited enzyme activity may present later in life with less severe hyperammonemia. CPS1 drives the first step in the urea cycle, the pathway terrestrial mammals utilize to metabolize nitrogen. In order to probe the effect of hyperammonemia on the developing nervous system and explore new therapies, a murine Cps1 exon 3-4 mutant was previously generated. However, these mice die within 24 h of birth, limiting study …

Fibroblast-Restricted Inflammasome Activation Promotes Atrial Fibrillation And Heart Failure With Diastolic Dysfunction, Luge Li, Cristian Coarfa, Yue Yuan, Issam Abu-Taha, Xiaolei Wang, Jia Song, Yuying Zeng, Xiaohui Chen, Amrit Koirala, Sandra L Grimm, Markus Kamler, Lisa K Mcclendon, Michelle Tallquist, Stanley Nattel, Dobromir Dobrev, Na Li

Faculty, Staff and Students Publications

Atrial fibrillation (AF) often coexists with heart failure, both involving inflammatory signaling and cardiac fibroblasts. To understand the role of fibroblast NLR family pyrin domain containing 3 (NLRP3) inflammasome in cardiac function, we found that NLRP3 was up-regulated in atrial fibroblasts from AF patients. Fibroblast-specific activation of NLRP3 in mice induced AF-promoting atrial myopathy and heart failure with diastolic dysfunction, accompanied by increased fibrosis, and reduced conduction velocity. Knockdown of NLRP3 prevented the AF-promoting atrial substrate and cardiomyopathy in the context of NLRP3 activation in fibroblasts. We identify the fibroblast NLRP3 inflammasome as a key pathway governing the promotion of …

Guidelines for management of heart failure with reduced ejection fraction (HFrEF) emphasize personalized care, patient engagement, and shared decision-making. Medications and cardiac rhythm management (CRM) devices are recommended with a high level of evidence. However, there are significant disparities: patients who could benefit from devices are frequently referred too late or not at all. Misconceptions about device therapy and the notion that the needs of patients (especially the prevention of sudden cardiac death) can now be met by expanding drug therapies may play a role in these disparities. This state-of-the-art review is produced by members of the DIRECT HF initiative, …

Formation Of An Expanding Memory Representation In The Hippocampus, Sachin P Vaidya, Guanchun Li, Raymond A Chitwood, Yiding Li, Jeffrey C Magee

Faculty, Staff and Students Publications

How brain networks connected by labile synapses store new information without catastrophically overwriting previous memories remains poorly understood. To examine this, we tracked the same population of hippocampal CA1 place cells (PCs) as mice learned a task for 7 days. We found evidence of memory formation as both the number of PCs maintaining a stable place field and the stability of individual PCs progressively increased across the week until most of the representation was composed of long-term stable PCs. The stable PCs disproportionately represented task-related learned information, were retrieved earlier within a behavioral session and showed a strong correlation with …

Role Of Kctd13 In Modulating Ar And Sox9 Expression In Different Penile Cell Populations, Carolina J Jorgez, Ahmed Chahdi, Hunter Flores, Marisol O'Neill, Abhishek Seth

Faculty, Staff and Students Publications

Objective: Micropenis is a condition with significant physical and psychological implications caused mainly by decreased androgen action in penile development. Kctd13-knockout (Kctd13-KO) mice have micropenis, cryptorchidism, and fertility defects because of reduced levels of androgen receptor (AR) and SOX9. We hypothesized that normalizing the levels of AR and SOX9 in the Kctd13-KO penis could help us to understand the mechanism of action of these signaling pathways on penile development.

Methods: We generated transgenic mice lacking Kctd13 and conditionally expressing AR in the urethral mesenchyme after Cre activation with Twist2cre (Kctd13-KO; AR-CMV; Twist2cre; herein called AR+), and Sox9 in the urethral …

From fertilization onwards, the cells of the human body acquire variations in their DNA sequence, known as somatic mutations. These postzygotic mutations arise from intrinsic errors in DNA replication and repair, as well as from exposure to mutagens. Somatic mutations have been implicated in some diseases, but a fundamental understanding of the frequency, type and patterns of mutations across healthy human tissues has been limited. This is primarily due to the small proportion of cells harbouring specific somatic variants within an individual, making them more challenging to detect than inherited variants. Here we describe the Somatic Mosaicism across Human Tissues …

Mass Spectrometry Imaging Reveals Alterations In Protein And N-Glycan Molecular Signatures In Endometriosis Tissues, Monica Lin, Erin H Seeley, Suzanne Ledet, Christina Salazar, Michael T Breen, Livia S Eberlin

Faculty, Staff and Students Publications

Endometriosis is a gynecological condition characterized by the uncontrolled growth of endometrial-like tissue outside the uterine cavity. Although highly prevalent, the biological mechanisms of endometriosis are poorly understood, and the disease is often misdiagnosed due to the unavailability of pre-operative diagnostic methods. Thus, better characterization of molecular markers of endometriosis are critical to improve our understanding of the disease and management of patients. Here, we used matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) imaging to investigate protein and N-glycan molecular signatures in eutopic endometrium and endometriosis lesions from tissues prospectively collected from patients. MALDI MS imaging of intact proteins …

Introduction: Chronic ocular graft-versus-host disease (oGVHD) is one of the most common complications after allogeneic hematopoietic stem cell transplantation (aHSCT). Recent studies indicate that desiccating stress by air-conditioning in transplantation wards increases the incidence of oGVHD. To test the hypothesis that experimental desiccating stress is a risk factor for oGVHD a mouse model of oGVHD was subjected to experimental desiccating stress.

Materials/methods: A previously established chemo-induced minor-mismatch mouse model of oGVHD was used. One group was challenged with desiccating stress for 18 days and compared to non-desiccated GVHD animals. Clinical phenotyping was performed weekly and ocular tissue and regional lymph …

Opioid-related mortality continues to claim tens of thousands of American lives annually. Medicaid plays an outsized role in financing opioid use disorder (OUD) treatment, paying for almost 40% of all Americans who received OUD treatment in 2017. Methods

Using Medicaid T-MSIS Analytic Files data and a novel data set of Medicaid managed care organization (MCO) plan coverage, we examined the relationship between comprehensiveness of benefits for OUD treatment provided by Medicaid MCO plans and the likelihood of OUD diagnosis and medications for OUD (MOUD) receipt among newly enrolled Medicaid beneficiaries in Kentucky. We use two stage least squares to …

Functional Time Transformation Model With Applications To Digital Health, Rahul Ghosal Ph.D., Marcos Matabuena, Sujit K. Ghosh

Faculty Publications

The advent of wearable and sensor technologies now leads to functional predictors which are intrinsically infinite dimensional. While the existing approaches for functional data and survival outcomes lean on the well-established Cox model, the proportional hazard (PH) assumption might not always be suitable in real-world applications. Motivated by physiological signals encountered in digital medicine, we develop a more general and flexible functional time-transformation model for estimating the conditional survival function with both functional and scalar covariates. A partially functional regression model is used to directly model the survival time on the covariates through an unknown monotone transformation and …

Good Faith Estimates And The No Surprises Act, Stuart L. Segelnick Dds, Ms

The New York State Dental Journal

Federal law requires dentists to be up front with self-pay patients about the cost of their treatment. Surprises may lead to penalties.

The No Surprises Act (NSA) went into effect on Jan. 1, 2022. This is a federal law that applies to all health-care providers, including dentists. The law gives certain rights to patients to help protect them from receiving surprise medical bills. These surprises usually occur when a person has no control over who treats them, such as during an emergency or when they are treated unknowingly by an out-of-network provider.
