Aging-Related Biomarker Discovery In The Era Of Immune Checkpoint Inhibitors For Cancer Patients, Abdullah Al-Danakh, Mohammed Safi, Yuli Jian, Linlin Yang, Xinqing Zhu, Qiwei Chen, Kangkang Yang, Shujing Wang, Jianjun Zhang, Deyong Yang

Faculty, Staff and Student Publications

Older patients with cancer, particularly those over 75 years of age, often experience poorer clinical outcomes compared to younger patients. This can be attributed to age-related comorbidities, weakened immune function, and reduced tolerance to treatment-related adverse effects. In the immune checkpoint inhibitors (ICI) era, age has emerged as an influential factor impacting the discovery of predictive biomarkers for ICI treatment. These age-linked changes in the immune system can influence the composition and functionality of tumor-infiltrating immune cells (TIICs) that play a crucial role in the cancer response. Older patients may have lower levels of TIICs infiltration due to age-related immune …

Editorial: Updates On Radiation-Induced Lymphopenia, Pim J J Damen, Steven H Lin, Peter S N Van Rossum

Faculty, Staff and Student Publications

Radiotherapy is a commonly employed and effective treatment for cancer, seeking to achieve an optimal balance between tumor cell death and minimizing damage to healthy tissues. Radiation-induced lymphopenia (RIL) is a common side effect due to the high radiosensitivity of lymphocytes even at low doses (< 1Gy), leading to their direct depletion (1). While the detrimental effects of radiotherapy on lymphocytes have been recognized since 1905, its influence on tumor control and survival has remained largely unclear until recently (2). Moreover, awareness and understanding of the prognostic effects of RIL remain limited in daily clinical practice.

Dissecting The Shared Genetic Architecture Between Alzheimer’S Disease And Frailty: A Cross-Trait Meta-Analyses Of Genome-Wide Association Studies, Nitesh Enduru, Brisa S Fernandes, Zhongming Zhao

Faculty, Staff and Student Publications

Introduction: Frailty is the most common medical condition affecting the aging population, and its prevalence increases in the population aged 65 or more. Frailty is commonly diagnosed using the frailty index (FI) or frailty phenotype (FP) assessments. Observational studies have indicated the association of frailty with Alzheimer's disease (AD). However, the shared genetic and biological mechanism of these comorbidity has not been studied.

Methods: To assess the genetic relationship between AD and frailty, we examined it at single nucleotide polymorphism (SNP), gene, and pathway levels.

Results: Overall, 16 genome-wide significant loci (15 unique loci) (p meta-analysis < 5 × 10-8) and 22 genes (21 unique genes) were identified between AD and frailty using cross-trait meta-analysis. The 8 shared loci implicated 11 genes: CLRN1-AS1, CRHR1 …

Faculty, Staff and Student Publications

BACKGROUND: While many molecular assays can detect mutations at low tumor purity and variant allele frequencies, complex biomarkers such as tumor mutational burden (TMB), microsatellite instability (MSI), and genomic loss of heterozygosity (gLOH) require higher tumor purity for accurate measurement. Scalable, quality-controlled, tissue-conserving methods to increase tumor nuclei percentage (TN%) from tumor specimens are needed for complex biomarkers and hence necessary to maximize patient matching to approved therapies or clinical trial enrollment. We evaluated the clinical utility and performance of precision needle-punch enrichment (NPE) compared with traditional razor blade macroenrichment of tumor specimens on molecular testing success.

METHODS: Pathologist-directed NPE …

An Ewas Of Dementia Biomarkers And Their Associations With Age, African Ancestry, And Ptsd, Mark W. Miller, Erika J. Wolf, Xiang Zhao, Mark W. Logue, Sage E. Hawn

Psychology Faculty Publications

Background

Large-scale cohort and epidemiological studies suggest that PTSD confers risk for dementia in later life but the biological mechanisms underlying this association remain unknown. This study examined this question by assessing the influences of PTSD, APOE ε4 genotypes, DNA methylation, and other variables on the age- and dementia-associated biomarkers Aβ40, Aβ42, GFAP, NfL, and pTau-181 measured in plasma. Our primary hypothesis was that PTSD would be associated with elevated levels of these markers.

Methods

Analyses were based on data from a PTSD-enriched cohort of 849 individuals. We began by performing factor analyses of the biomarkers, the results of which …

Regular aerobic activity is associated with a reduced risk of chronic pain in humans and rodents. Our previous studies in rodents have shown that prior voluntary wheel running can normalize redox signaling at the site of peripheral nerve injury, attenuating subsequent neuropathic pain. However, the full extent of neuroprotection offered by voluntary wheel running after peripheral nerve injury is unknown. Here, we show that six weeks of voluntary wheel running prior to chronic constriction injury (CCI) reduced the terminal complement membrane attack complex (MAC) at the sciatic nerve injury site. This was associated with increased expression of the MAC inhibitor …

Meta-Analysis Of The Vmp-Like Sequences Of Lyme Disease Borrelia: Evidence For The Evolution Of An Elaborate Antigenic Variation System, Steven J Norris, Kalvis Brangulis

Faculty, Staff and Student Publications

VMP-like sequence (vls) antigenic variation systems are present in every Lyme disease Borrelia strain with complete genome sequences. The linear plasmid-encoded vls system consists of a single expression site (vlsE) and contiguous array(s) of silent cassettes that have ~90% identity with the central cassette region of the cognate vlsE gene; antigenic variation occurs through random, segmental, and unidirectional recombination of vls silent cassette sequences into the vlsE expression site. Automated annotation programs do not accurately recognize vls silent cassette sequences, so these regions are not correctly annotated in most genomic sequences. In this study, the vls …

Tissue Transglutaminase: A Multifunctional And Multisite Regulator In Health And Disease, Zhouzhou Yao, Yuhua Fan, Lizhen Lin, Rodney E Kellems, Yang Xia

Faculty, Staff and Student Publications

Tissue transglutaminase (TG2) is a widely distributed multifunctional protein involved in a broad range of cellular and metabolic functions carried out in a variety of cellular compartments. In addition to transamidation, TG2 also functions as a Gα signaling protein, a protein disulfide isomerase (PDI), a protein kinase, and a scaffolding protein. In the nucleus, TG2 modifies histones and transcription factors. The PDI function catalyzes the trimerization and activation of heat shock factor-1 in the nucleus and regulates the oxidation state of several mitochondrial complexes. Cytosolic TG2 modifies proteins by the addition of serotonin or other primary amines and in this …

Knowledge Mapping Of Anaplastic Thyroid Cancer Treatments: A Bibliometric Analysis (2000–2023), Shiqiang Liu, Xingmin Yan, Yalong Yang, Yun Xia, Panshi Zhang

Faculty, Staff and Student Publications

Context: Anaplastic thyroid cancer (ATC) is a relatively rare and extensively malignant kind of thyroid carcinoma. The poor prognosis and high mortality rate of ATC can be attributed to its invasive features and undifferentiated phenotype. At present, there is a lack of efficacious therapeutic options. In light of the elevated fatality rate, it is vital to possess a comprehensive comprehension of the scientific terrain pertaining to ATC. To gather the perspectives of different researchers about the topic of ATC treatment, we did a bibliometric network analysis, which offers a comprehensive view of the scholarly literature.

Methodology: A systematic search was …

Treatment Comparisons In Adaptive Platform Trials Adjusting For Temporal Drift, Beibei Guo, Li Wang, Ying Yuan

Faculty, Staff and Student Publications

An adaptive platform trial (APT) is a multi-arm trial in the context of a single disease where treatment arms are allowed to enter or leave the trial based on some decision rule. If a treatment enters the trial later than the control arm, there exist non-concurrent controls who were not randomized between the two arms under comparison. As APTs typically take long periods of time to conduct, temporal drift may occur, which requires the treatment comparisons to be adjusted for this temporal change. Under the causal inference framework, we propose two approaches for treatment comparisons in APTs that account for …

Background: The CO2 laser is frequently used during microlaryngeal surgery (MLS) for a variety of pathology including laryngeal malignancy and stenosis. Learning how to use the laser safely is part of the curriculum for every otolaryngology resident. However, assessment of laryngoscopy technical skills can be challenging for supervisors, making it difficult to adequately provide feedback to trainees.

Objectives: "LAser Surgical skills Evaluation for Residents" (LASER) Scale aims to facilitate the evaluation of residents' performance and promote constructive feedback.

Methods: The initial evaluation grid was based on a literature review of CO2 laser laryngoscopy (with an emphasis on indications, technique, safety, …
