Objective:
The overarching theme of the current research is to identify additional in utero chemical risk factors for childhood acute lymphoblastic leukemia (ALL) in an ethnically diverse population, and to understand how chemicals increase risk via immunological, genetic and epigenetic mechanisms. We will use state-of-the-art methods to measure in utero chemical exposures that are potential risk factors for childhood leukemia and to characterize the biological mechanisms by which these chemicals may act on the fetus to increase the risk of leukemia in human and animal studies. Below is a summary for the progresses in each Core and Project. Overall, we estimate that we are above 50% completion, and anticipate to accelerate the pace of the laboratory work and statistical analyses now that 99% of biospecimens are available.
Progress Summary:
Project 1 on immune function is making progress towards completion of the aims. The biospecimens for the mother-child pairs are now available and laboratory work to measure cytokines in children has been completed. We have analyzed the cytokine profiles of 137 cases of childhood ALL and 499 matched control subjects. The cytokines included IL-1β, IL-4, IL-6, IL-8, IL-10, IL-12p70, GM-CSF, TNF- α, and VEGF. As we observed high correlations across the cytokines and were concerned about colinearity, we utilized the principle component approach to derive six components that are independent from each other. Since the first three components explained more than 72% of the variance, we decided to focus on these components. When we compared the components between cases and controls, both Components 1 and 3 were significantly associated with the risk of childhood ALL. While it is premature to draw conclusions at this point, it appears that our hypothesis regarding the role of immunomodulatory cytokines in leukemogenesis is supported by the current data. Biospecimens from the subjects in the California Childhood Leukemia Study (CCLS) will be tested next. While waiting for more cytokine data, our group continued to analyze epidemiologic and socio-demographic data from our linkage study.
Project 2 on fetal exposome is making progress towards completion of the aims for both the metabolomic and adductomic experiments. The small-molecule features have been measured and annotated in the archived newborn blood specimens (ANBS) from 400 childhood leukemia cases and matching controls from CCLS as proposed. Using the bioinformatics pipeline developed in this project for small molecules, over 800 common metabolic features were compared between ALL cases and controls. Feature selection pointed to potential roles of several lipids in the etiology of ALL, including linolenic and linoleic acids and phospholipids with 18:2 and eicosatetraenoic acid moieties. Significantly, many of the selected metabolites were highly associated with breastfeeding practice in children diagnosed with ALL after age 6, suggesting that particular nutrients in breast milk are protective for ALL. The method developed for characterization of HSA adduct features was validated with a set of 46 ANBS from control children, half with mothers who smoked during pregnancy and half with nonsmoking mothers. Using the bioinformatics pipeline and statistics package developed in this project, a total of 26 adducts were identified, and one HSA adduct feature (from reaction with cyanide) was highly predictive of smoking status (higher in children of smoking mothers). This is consistent with literature reports that cyanide levels are higher in blood of smokers than of nonsmokers and indicates that our adductomics methodology using a small amount of blood from the ANBS is appropriate for comparing CL cases to controls to find discriminating features. We are now applying the laboratory and statistical pipeline to the full set of 400 cases and 400 controls from the CCLS.
Project 3 on methylation is making progress towards completion of the aims. We have continued to analyze existing DNA methylation data on ANBS, and construct new datasets using updated DNA methylation arrays (Illumina HM850K). More samples are currently being analyzed at the laboratory and will be available for analyses in a couple of months. We have also participated in PACE Consortium (Pregnancy and Childhood Epigenetics) activities which involve the meta-analysis of our HM450K methylation data with many other groups also studying neonatal DNA methylation patterns caused by environmental and demographic variations among populations. Our work with colleagues at the International Agency for Research on Cancer on DNA methylation events that predict leukemia case status has resulted in several replicable DNA methylation biomarkers at birth that predict future leukemia risk. These marks include CpGs within the genes MGMT, HLA-B, ABR, and VTRNA2-1. We are further exploring potential DNA methylation gene X environment interactions, in particular for the MGMT gene which is a DNA repair gene, and HLA-B, which is a part of a complex of immune response genes. Our research group is also heavily involved in a new field called ''immunomethylomics,'' which is the analysis of blood cell types by their DNA methylation patterns and how this influences biology and disease incidence and progression. We have continued work on optimizing our mouse model for leukemia and preparing relevant chemical dosing strategies. This work was completed for PCBs, and we have performed reduced representation bisulfite sequencing on pups from treated and untreated animals. Statistical analyses are underway.
The Administrative Core (Core A): continues to support the infrastructure and scientific direction of the Center. We completed the selection and acquisition of the biospecimens that were available at the CA biobank, and are in the process of upgrading the data linkage to meet our target sample size for mother-child pair specimens. Specimens are being used for all three Projects, ensuring sufficient overlap for future integration of the data generated on cytokines (Project 1), exposome and protein adducts (Project 2), and genetic/epigenetic (Project 3). The Community Outreach and Translation Core (COTC) has established a distinguished community advisory group that held its third meeting in February 2018. The Internal Advisory Committee continues to meet every two months to provide updates on all Cores and Projects, and to facilitate scientific interaction between CIRCLE investigators. We plan to hold the next External Advisory Committee meeting in early 2019.
The career development investigator is working closely with the leaders of all Cores and Projects. His main role this year was to ensure integration between projects (such as adductomic and epigenetic data) and shared biospecimens. He also is pursuing his own innovative research and submitted several grants. Dr. Whitehead was successfully awarded a new R24 grant, (with PI Catherine Metayer) where he is leading the work on examining the association between maternal stress during pregnancy and child telomere length, and his/her subsequent risk of leukemia. Dr. Whitehead collaborated with the tobacco prevention program at University of California at San Francisco (UCSF) to design an intervention study to reduce exposure to third-hand tobacco, using dust sampling as objective measures (grant under review).
As indicated in an email to Nica Louie on December 19th, 2017, Joe Wiemels (Leader of Project 3 and Co-Investigator of Project 1) transitioned his primary affiliation from UCSF to USC effective January 1st, 2018. Because Dr. Wiemels has continued to keep an affiliation at UCSF, he was able to continue to serve as the EPA subcontract PI at UCSF for these projects for the past year (Year 3 of the grant), working closely with our other UCSF-based investigator Scott Kogan (who is the current leader of the CIRCLE mouse modeling Core to support Aims in Projects 1 and 3, and who has overseen work done at UCSF during Joe's transition to USC). We will continue to conduct the EPA-supported work at UCSF in Year 4, and therefore we propose to list Dr. Scott Kogan as the UCSF subaward PI for the EPA portion (note that Joe Wiemels will be the USC subaward PI for the NIEHS portion of the grant). Both Drs. Kogan and Wiemels will be in regular contact by email and phone to coordinate the work for Projects 1 and 3. This change will be seamless as (i) we will be able to accomplish our aims, (ii) there is no change in key personnel, and (iii) the change is cost neutral.
The Community Outreach and Translation Core (COTC, Core B): This core continues to be extremely active in translating the findings from CIRCLE and from other relevant research groups (such as the Childhood Leukemia International Consortium, CLIC) to various audiences. The COTC aims to improve pediatric environmental health literacy amongst the clinical audiences by organizing and giving presentations and symposia including at the Pediatric Academic Societies, the annual Children with Cancer UK conference, UCSF Pediatric Malignancies Program, and the International Society for Environmental Epidemiology. Also, we partnered with the California EPA, Office of Environmental Health Hazard Assessment and the Western States Pediatric Environmental Health Specialty Unit (PEHSU) to produce a children's environmental health symposium in Sacramento in April 2017 on ''Environmental Justice and Children.'' This was the first ever symposium to focus specifically on this issue and is relevant to our CIRCLE COTC aims as many of the environmental justice community exposures of concern are also linked to childhood leukemia risk. Dr. Miller also joined with others to create a work group to develop changes to National Cancer Institute (NCI) materials to address the potential roles of environmental exposures in childhood cancer and include actions that might reduce risks.
The Story Of Health (SOH) e-book continues to be successful. We have continued working with the Western States PEHSU and other partners and in fall 2017 released the fourth chapter of the Story of Health (SOH) multimedia eBook (on infertility and reproductive health). So far, the SOH has had over 8,800 registrations for physician, nurse, and health educator continuing education (CE) credit representing approximately 14,000 hours of CE credits to be awarded by the CDC. We have developed a low literacy version of the SOH, in an innovative comic book format in both English and Spanish, for use in our various anticipated programs. These will be used in our outreach programs, particularly in our trainings for Promotoras de Salud (lay health workers). The COTC has produced also an innovative ''shadow puppet theater'' short video titled ''Love in the Time of Toxicants''. This provides an alternative format for introducing the ideas in the Story of Health materials for a general community audience. It is available in English and Spanish and has been well received in the US as well as Mexico (https://wspehsu.ucsf.edu/projects/improving-environmental-health-literacy-young-adults/). The materials described above were released and are available in Spanish and specifically address the needs of the Latino community. They have been used in numerous workshops presented to parents, promotores de salud (lay health workers), child care workers, and at health fairs.
The Mouse Model Facility (Core C): This core has worked with CIRCLE investigators to identify chemicals to be tested on the leukemia prone-mouse model. The PCB models have been completed. Our results show that for the PCB models we studied, under the exposure regimen and in the environment of a specific pathogen-free facility, we did not observe an impact of prenatal PCB exposure on disease. Our experience with the PCB cohorts has enabled us to refine our exposure studies by using an alternative mouse model more prone to develop leukemia, and we are moving forward with the testing of additional agents. The Core is currently exposing pregnant mice to tobacco in the form of third hand smoke, to the PAH dibenz[a,h]anthracene, and to the insecticides Permethrin and Cypermethrin.
Future Activities:
Core A will continue to provide infrastructure support and scientific direction to the other Cores and Projects. Core B-COTC will continue to promote environmental health literacy to clinicians and targeted audiences such as Latino families, using innovative translation tools such as the comic book, and the updated version of the SOH E-book, and videos. Projects 1, 2, and 3 will continue the laboratory work to characterize cytokine profile, exposome/adductome, and methylation profile, respectively, and will continue to analyze the data, while developing statistical methods to better fit the complexity of multi-dimensional data. Another emphasis will be on integrating analyses from all Projects. Core C will continue to conduct mouse model experiments to test leukemogenic potential of selected chemicals, and provide biospecimens for Project 1 (cytokines assays) and 3 (methylation assays).
