Background: Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD), which are moderately heritable, frequently co-occur and contribute to significant public health burdens, particularly among economically disadvantaged urban communities. There are noted sex differences in PTSD and AUD outcomes, with evidence suggesting women have heightened susceptibility to stress-related alcohol use. Preliminary PTSD-AUD ecological momentary assessment (EMA) findings support bidirectional associations across clinical outcomes. However, no studies to date have used PTSD-AUD comorbidity models as organizing frameworks to examine the temporal ordering and stability of within-person symptom dynamics underlying the maintenance or exacerbation of PTSD and AUD symptoms, including bidirectional and …

To examine effects of a multilevel, religiously-tailored HIV testing intervention, Taking It to the Pews (TIPS), on receipt of HIV testing with African American church-affiliated populations, 14 African American churches (N = 1,491) were randomized to TIPS or a multilevel, non-tailored HIV education attention-control arm in a cluster-randomized trial (Kansas City urban area, 2013 to 2019). Receipt of an HIV test was examined using objective data and participant self-reports (last 12 months), including self-reported exposure to intervention components. Overall, 471 HIV tests were completed; TIPS intervention churches conducted significantly more tests than controls (339 versus 132, p = 0.003). Also, …

Stability Of Salivary Microrna Measures Across An Ncaa Division I Football Season: Implications For Microrna As A Biomarker Of Concussion, Thomas R. Campbell, Martina Zamponi, Delaney Leathers, Julie Cavallario, Jessica C. Martinez, Peter A. Mollica

Rehabilitation Sciences Faculty Publications

Background

Clinicians often face challenges in concussion care due to a heavy reliance on subjective patient input. Recently, research has sought objective biomarkers, like salivary microRNAs, to improve concussion management. However, significant limitations hinder the use of microRNAs as a diagnostic tool, including the cumulative effects of a contact sport season. A better understanding of the response to a contact sport season would help researchers and clinicians interpret expression changes at the time of injury in the context of seasonal variation. in Therefore, this study investigated the reliability of previously identified salivary microRNA targets across one contact sport season.

Genetic Variants Associated With Sjögren’S Disease Subtypes Stratified By Clinical Feature, Nitesh Enduru, Chihiro Iwaya, Akiko Suzuki, Zhongming Zhao, Junichi Iwata

Faculty, Staff and Student Publications

Introduction: Sjögren's disease (SjD) is a chronic autoimmune disorder characterized by dry mouth (xerostomia) and dry eyes (xerophthalmia) due to inflammation in exocrine glands, particularly the salivary and lacrimal glands. The condition presents a wide variety of clinical features, suggesting that it may involve heterogeneous conditions without a clear boundary. Although genome-wide association studies (GWAS) have identified several genetic variants associated with SjD, their roles in SjD pathogenesis remain unclear.

Methods: In this study, we aimed to identify single-nucleotide polymorphisms (SNPs) associated with SjD by categorizing patients based on four diagnostic markers: anti-Ro/SSA and anti-La/SSB antibodies, IgG levels, and lymphocyte …

Peripheral Cd200r Signaling: A Critical Regulator Of Post-Stroke Inflammation In Aged Mice, Conelius Ngwa, Afzal Misrani, Yan Xu, Jingjing Wang, Rodney Ritzel, Fudong Liu

Faculty, Staff and Student Publications

The immune responses to ischemic stroke are subjected to endogenous inhibitory pathways that delimitate the post-stroke inflammation. Among them, the interaction between CD200 and its receptor (CD200R) is increasingly recognized for its role in regulating neuroinflammation across various central nervous system (CNS) disorders. In the present study, we have examined the role of central (brain) vs. peripheral CD200R signaling in acute ischemic stroke using aged bone marrow chimeric (BMC) mice (16-19 months old). These chimeras were generated by transplanting bone marrow from CD200R knockout (KO), green fluorescent protein (GFP), or wild-type (WT) donor mice into irradiated recipient mice, and then …

NSD2 catalyses the epigenetic modification H3K36me2 (refs. 1,2) and is a candidate convergent downstream effector of oncogenic signalling in diverse malignancies3–5. However, it remains unclear whether the enzymatic activity of NSD2 is therapeutically targetable. Here we characterize a series of clinical-grade small-molecule catalytic NSD2 inhibitors (NSD2i) and show that the pharmacological targeting of NSD2 constitutes an epigenetic dependency with broad therapeutic efficacy in KRAS-driven preclinical cancer models. NSD2i inhibits NSD2 with single-digit nanomolar half-maximal inhibitory concentration potency and high selectivity over related methyltransferases. Structural analyses reveal that the specificity of NSD2i for NSD2 …

Faculty, Staff and Student Publications

Despite the promise of immune checkpoint blockade (ICB) in head and neck squamous cell carcinoma (HNSCC), mediators of response are poorly understood. To address this, here we analyzed oropharyngeal HNSCCs treated with neoadjuvant durvalumab (anti-PDL1) alone or in combination with tremelimumab (anti-CTLA4) from the CIAO clinical trial ( NCT03144778 ). We found that only the total abundance of intratumoral bacteria predicted ICB response, which was validated in multiple independent cohorts. High intratumoral bacteria abundance was associated with an immunosuppressive tumor microenvironment, characterized by an accumulation of neutrophils coupled with depletion of T cells and other adaptive immune cells. Experimental elevation …
