Concurrent chemoradiotherapy (cCRT) is the mainstay of treatment for patients diagnosed with locally advanced non-small cell lung cancer (NSCLC). One significant challenge in the effectiveness of this therapy is the potential development of resistance mechanisms, where autophagy up-regulation has been proposed as a key contributing factor. However, there is a lack of reliable biomarkers to predict outcomes on these patients. Interestingly, for addressing this gap, extracellular vesicles (EVs) and circulating tumor cells (CTCs) have emerged as potential sources of such biomarkers. In this study, we investigated EV-associated miRNAs and presence of autophagic CTCs in prospectively collected serial samples from 38 …

Dissociable Effects Of Alzheimer's Disease-Related Cognitive Dysfunction And Aging On Functional Brain Network Segregation, Ziwei Zhang, Micaela Y Chan, Liang Han, Claudia A Carreno, Ezra Winter-Nelson, Gagan S Wig

Faculty, Staff and Student Publications

Alzheimer's disease (AD) is associated with changes in large-scale functional brain network organization. Individuals with AD exhibit less segregated resting-state brain networks compared with individuals without dementia. However, declines in brain network segregation are also evident as adult individuals grow older. Determining whether these observations reflect unique or overlapping alterations on the functional connectome of the brain is essential for understanding the impact of AD on network organization and incorporating measures of functional brain network organization toward AD characterization. Relationships between AD dementia severity and participant's age on resting-state brain system segregation were examined in 326 cognitively healthy and 275 …

School of Graduate Studies Faculty Publications

SARS-CoV-2 mRNA vaccines are administered as effective prophylactic measures for reducing virus transmission rates and disease severity. To enhance the durability of post-vaccination immunity and combat SARS-CoV-2 variants, boosters have been administered to two-dose vaccinees. However, long-term humoral responses following booster vaccination are not well characterized. A 16-member cohort of healthy SARS-CoV-2 naïve participants were enrolled in this study during a three-dose BNT162b2 vaccine series. Serum samples were collected from vaccinees over 420 days and screened for antigen (Ag)-specific antibody titers, IgG subclass distribution, and neutralizing antibody (nAb) responses. Vaccine boosting restored peak Ag-specific titers with sustained α-RBD IgG and …

The Role Of Noncoding Rnas In Pancreatic Birth Defects, Ziyue Zoey Yang, Ronald J Parchem

Faculty, Staff and Students Publications

Congenital defects in the pancreas can cause severe health issues such as pancreatic cancer and diabetes which require lifelong treatment. Regenerating healthy pancreatic cells to replace malfunctioning cells has been considered a promising cure for pancreatic diseases including birth defects. However, such therapies are currently unavailable in the clinic. The developmental gene regulatory network underlying pancreatic development must be reactivated for in vivo regeneration and recapitulated in vitro for cell replacement therapy. Thus, understanding the mechanisms driving pancreatic development will pave the way for regenerative therapies. Pancreatic progenitor cells are the precursors of all pancreatic cells which use epigenetic changes …

A Paracrine Circuit Of Il-1Β/Il-1r1 Between Myeloid And Tumor Cells Drives Genotype-Dependent Glioblastoma Progression, Zhihong Chen, David H. Gutmann, Et Al.

2020-Current year OA Pubs

Monocytes and monocyte-derived macrophages (MDMs) from blood circulation infiltrate glioblastoma (GBM) and promote growth. Here, we show that PDGFB-driven GBM cells induce the expression of the potent proinflammatory cytokine IL-1β in MDM, which engages IL-1R1 in tumor cells, activates the NF-κB pathway, and subsequently leads to induction of monocyte chemoattractant proteins (MCPs). Thus, a feedforward paracrine circuit of IL-1β/IL-1R1 between tumors and MDM creates an interdependence driving PDGFB-driven GBM progression. Genetic loss or locally antagonizing IL-1β/IL-1R1 leads to reduced MDM infiltration, diminished tumor growth, and reduced exhausted CD8+ T cells and thereby extends the survival of tumor-bearing mice. In contrast …

UNLABELLED: The malignant Hodgkin and Reed Sternberg (HRS) cells of classical Hodgkin lymphoma (cHL) are scarce in affected lymph nodes, creating a challenge to detect driver somatic mutations. As an alternative to cell purification techniques, we hypothesized that ultra-deep exome sequencing would allow genomic study of HRS cells, thereby streamlining analysis and avoiding technical pitfalls. To test this, 31 cHL tumor/normal pairs were exome sequenced to approximately 1,000× median depth of coverage. An orthogonal error-corrected sequencing approach verified >95% of the discovered mutations. We identified mutations in genes novel to cHL including: CDH5 and PCDH7, novel stop gain mutations in …

Differential Contribution Of Cardiac And Peripheral Blood Flow To Metaboreceptor-Mediated Pressor Responses In Autism Spectrum Disorder, Matthew Pizano Gomez, Gabriel B. Carlota, Stephanie S. Wang, Areum K. Jensen

International Journal of Exercise Science: Conference Proceedings

Young adults with Autism Spectrum Disorder (ASD) experience a higher prevalence of hypertension than the general population. Abnormal blood pressure (BP) response to acute exercise is seen in hypertension. BP response evoked during exercise is the outcome of a central interaction between neural inputs such as the exercise pressor reflex. However, it is unclear if this neurocardiovascular interaction is altered differently to regulate BP during exercise in ASD. PURPOSE: To determine whether contributions of cardiac and peripheral blood flow to metaboreceptor-mediated pressor responses are different during exercise in ASD. METHODS: 21 young adults with and without ASD completed the study. …

International Journal of Exercise Science: Conference Proceedings

Characterizing exercise gas exchange response dynamics reveals important information about physiological control processes and cardiopulmonary dysfunction. However, current methods for extracting exercise response dynamics typically use multiple step-wise transitions, limiting applicability of this technique. PURPOSE: We designed a new protocol (chirp waveform) to extract exercise gas exchange response dynamics in a single visit. We tested the hypothesis that gas exchange response dynamics extracted from chirp forcing would be similar to those extracted from step-wise transitions. METHODS: Thirty-one participants (14 young healthy, 7 older healthy, and 10 patients with chronic obstructive pulmonary disease) visited the laboratory on three occasions. …

Low Back Demand Of Equipment Carriage Tasks In Golf, Guanrong Cai, Jacob Cho, Yunsheng Zou, Jordan Cannon, George Salem

International Journal of Exercise Science: Conference Proceedings

Low back injury is a common concern in golfers and caddies. The literature often points to the biomechanics of the golf swing as the major contributing factor; however, golfers and caddies can regularly walk upward of 10,000 steps on uneven terrain while carrying equipment, which can contribute to the cumulative load on the low back. PURPOSE: To examine the low back biomechanical demands during golf equipment carriage and pick-up tasks. METHODS: Sixteen golfers (11M/5F, 27.4±3.5yrs) participated in 3D motion capture of a golf bag pick-up task and 3 walking tasks (1. unloaded walking [UW], 2. unilateral carrying on …
