Age-Associated Proteins Explain The Role Of Medial Temporal Lobe Networks In Alzheimer’S Disease, Adam Turnbull, Yejin Kim, Kai Zhang, Xiaoqian Jiang, Zihuai He, Victor W Henderson, F Vankee Lin

Faculty, Staff and Student Publications

The structural connectivity (SC) of the medial temporal lobe and its associated cortical anterior temporal and posterior medial networks (MTL-AT-PM) is linked to pathologies and memory decline in Alzheimer's disease (AD). However, neuroimaging analyses cannot tell us how SC changes occur in AD at the molecular level and do not provide a means of intervening to slow/prevent pathology-related changes in MTL-AT-PM SC. The current study aimed to understand how and where AD-related changes occur within MTL-AT-PM using proteomics. We used a 4-step approach in 101 older adults from a local sample, aiming to understand how proteins and SC in combination …

Manual Therapy For Fibrosis-Related Late Effect Dysphagia In Head And Neck Cancer Survivors: The Mantle Nonrandomized Clinical Trial, Holly Mcmillan, Carla L Warneke, Sheila Buoy, Christine Porsche, Kiara Savage, Stephen Y Lai, Clifton D Fuller, Katherine A Hutcheson

Faculty, Staff and Student Publications

Importance: Late radiation-associated dysphagia (RAD) after head and neck cancer (HNC) treatment is challenging and commonly treatment refractory, with fibrosis stiffening connective tissues and compressing peripheral nerve tracts, contributing to diminished strength and possibly denervation of swallowing muscles. Manual therapy (MT), while common for cancer-related pain and other indications, remains largely unstudied for fibrosis-related late RAD.

Objective: To determine the feasibility and safety of MT, estimate effect size and durability of MT for associated improvements in cervical range of motion (CROM), and examine functional outcomes after MT in survivors of HNC with fibrosis-related late RAD.

Design, setting, and participants: This …

Background: Although the administration of tyrosine-kinase inhibitors in ALK-rearranged NSCLC has revolutionized precision medicine, the detection of gene rearrangements from liquid biopsies remains challenging. RNA-based detection has revealed promising sensitivity for rearrangement detection and thus we hypothesize that a liquid biopsy assay analyzing circulating tumor RNA (ctRNA) in addition to circulating tumor DNA (ctDNA) will improve detection. Furthermore, we hypothesize that the detection of gene fusions at baseline will correlate with clinical outcomes.

Methods: We retrospectively analyzed 86 plasma samples from 33 patients enrolled in the BRIGHTSTAR clinical trial assessing local consolidative therapy (LCT) and brigatinib in patients with …

Like all organs, the thymus grows in size and function rapidly during development, but this growth comes to a halt after birth. However, the molecular mechanisms behind such a transition in the thymus remain obscure. Using single-cell RNA sequencing (scRNA-seq) of the murine thymic stroma, we identified that major transcriptomic changes occur in the endothelium and mesenchyme across the transition to homeostasis. Differentially expressed gene and intercellular network analyses of temporally resolved scRNA-seq data revealed fibroblast-derived insulin-like growth factor 2 (IGF2) as a candidate driving neonatal thymic expansion. We demonstrated that IGF2 activity promotes a cortical thymic epithelial cell-specific proliferation …

Faculty, Staff and Student Publications

Acute undifferentiated leukemia (AUL) is a rare hematologic malignancy lacking lineage‐specific markers. Concurrent, clonally related AUL and T‐lymphoblastic lymphoma (T‐LBL) has not been reported previously. Here we describe a patient who was diagnosed with AUL in the bone marrow and T‐LBL in the mediastinum after a thorough immunophenotyping by flow cytometry and immunohistochemistry. Despite their immunophenotypic differences, the AUL and T‐LBL showed identical genetic alterations: SET::NUP214 fusion, PHF6, and EZH2 mutations. The patient achieved and remained in complete remission after chemotherapy and stem cell transplantation. This case underscores the value of comprehensive immunophenotyping and genetic analysis in rare hematologic …

Tumours of the appendix — a vestigial digestive organ attached to the colon — are rare. Although we estimate that around 3,000 new appendiceal cancer cases are diagnosed annually in the USA, the challenges of accurately diagnosing and identifying this tumour type suggest that this number may underestimate true population incidence. In the current absence of disease-specific screening and diagnostic imaging modalities, or well-established risk factors, the incidental discovery of appendix tumours is often prompted by acute presentations mimicking appendicitis or when the tumour has already spread into the abdominal cavity — wherein the potential misclassification of appendiceal tumours as …
