Expanding Anti-Cd38 Immunotherapy For Lymphoid Malignancies, Xu Wang, Xinfang Yu, Wei Li, Praveen Neeli, Ming Liu, Ling Li, Mingzhi Zhang, Xiaosheng Fang, Ken H Young, Yong Li

Faculty, Staff and Students Publications

BACKGROUND: Lymphoid neoplasms, including multiple myeloma (MM), non-Hodgkin lymphoma (NHL), and NK/T cell neoplasms, are a major cause of blood cancer morbidity and mortality. CD38 (cyclic ADP ribose hydrolase) is a transmembrane glycoprotein expressed on the surface of plasma cells and MM cells. The high expression of CD38 across MM and other lymphoid malignancies and its restricted expression in normal tissues make CD38 an attractive target for immunotherapy. CD38-targeting antibodies, like daratumumab, have been approved for the treatment of MM and tested against lymphoma and leukemia in multiple clinical trials.

METHODS: We generated chimeric antigen receptor (CAR) T cells targeting …

The Effect Of Fiber And Omega-6:Omega-3 Fatty Acid Ratio On Asthma And Asthma-Related Symptoms In An Adult U.S. Population, Korie As Nelson

Capstone Experience: Master of Public Health

Asthma is one of the most common diseases in the world affecting more than 10% of adults in many westernized countries and 339 million globally. Studies have shown a positive association between increased dietary fiber and improvement in asthma-related inflammation. Omega-3 fatty acids have also been shown to help mitigate inflammation in general. No identified studies have looked at the synergistic effect of omega-3 and omega-6 fatty acids alone and as a ratio with fiber on asthma, lung function, and respiratory morbidities. A positive association could mean that dietary interventions of fiber and fatty acids could significantly improve asthma and …

Faculty, Staff and Students Publications

To identify genetic variants for risk of squamous cell carcinoma of the head and neck (SCCHN), we conducted a two-phase genome-wide association study consisting of 7,858,089 SNPs in 2,171 cases and 4,493 controls of non-Hispanic white, of which 434,839 typed and 7,423,250 imputed SNPs as the discovery. SNPs with P <1×10–3 were further validated in the OncoArray study of oral and pharynx cancer (5,205 cases and 3,232 controls of European ancestry) from dbGaP. Meta-analysis of the discovery and replication studies identified one novel locus 6p22.1 (P = 2.96×10–9 for the leading rs259919) and two cancer susceptibility loci 6p21.32 (rs3135001, HLA-DQB1) and 6p21.33 (rs1265081, CCHCR1) associated with SCCHN risk. Further stratification by tumor site revealed four known cancer loci (5p15.33, 6p21.32, 6p21.33, and 2p23.1) associated with oral cavity cancer risk and oropharyngeal cancer risk, respectively. In addition, one novel locus 18q22.2 (P = 2.54×10–9 for the leading SNP rs142021700) was identified for hypo-pharynx and larynx cancer risk. For SNPs in those reported or novel loci, we also performed functional annotations by bioinformatics prediction and eQTL analysis. Collectively, our identification of four reported loci (2p23.1, 5p15.33, 6p21.32, and 6p21.33) and two novel loci (6p22.1 and 18q22.2) for SCCHN risk highlight the importance of HLA loci for oropharyngeal cancer risk, suggesting that immunologic mechanisms are implicated in the etiology of this subset of SCCHN.
