Scientific Advisory Committee Holds Annual Meeting at Hiroshima RERF Over Three Days

The 46th meeting of the Scientific Advisory Committee (SAC), an external body of scientific experts that advises RERF on research, was held March 22–24, 2019, at RERF’s Hiroshima Laboratory.

The SAC does not review all departments at RERF each year, since an enormous volume of research results has been generated using long-term follow-up data donated by the A-bomb survivors. The department to be reviewed changes each year, and this year the Department of Molecular Biosciences (MBS) underwent comprehensive review. The planned Research Resource Center (RRC), of which the Biosample Research Center (BRC) will be a major component, underwent special review.

For this purpose, along with 10 regular SAC members from the U.S. and Japan, five Special Scientific Advisors were appointed, two more than were appointed last year: two such experts from the U.S. and one from Japan were requested to facilitate the review of MBS, and one expert from the U.S. and two from Japan with expertise in integrated data resource and biobank operations were appointed for the RRC review. The RRC has been identified as the highest priority activity of RERF for its future success, resulting in the addition to the SAC this time of these experts in those particular fields.

Dr. Ohtsura Niwa, RERF Chairman, opened the meeting, on March 22, with his greetings from RERF. Dr. Robert L. Ullrich, Vice Chairman and Chief of Research, followed with an overview of RERF’s responses to the SAC recommendations from the previous year, as well as with highlights of RERF’s research activities. He explained the importance of strategic planning, and within such plans, of RERF’s continuation of “mission-based studies.” These studies are defined as RERF’s core research into the late health effects of radiation from the atomic bombings in the A-bomb survivors as well as dosimetry studies.

Dr. Ullrich’s presentation also touched on the strategic plans for the RRC and the utilization of biosamples stored at the BRC. He emphasized the importance of the use of RERF’s biosamples in both DNA and non-DNA sequencing studies. Later, presentations were made regarding RERF’s infrastructure, including the planned RRC and the importance of this center for implementation of collaborative research with other organizations as well as for RERF’s future.

The Department of Statistics, which underwent comprehensive review last year, gave responses to last year’s SAC recommendations as well as an explanation of its current activities. Next, the MBS Department gave detailed presentations on the research it currently conducts.

On March 23, the second day of the meeting, the advisors held discussions with the principals regarding the work of the recently established Research Cluster System, which comprises the three clusters of Cancer, Genetics, and Non-Cancer. The cluster system is designed to group together scientists from different departments to work on shared research projects. The Research Cluster System garnered considerable interest and praise from the SAC members.

To close out the day, Dr. Niwa, Dr. Ullrich, and Dr. Kazunori Kodama, Executive Director, explained RERF’s strategic plans for its overall operations in the future.

On the final day, March 24, the SAC deliberated on its recommendations for RERF and discussed their recommendations with RERF leadership. In the late afternoon, following the deliberations, a press conference was held, gathering five media organizations. To start the press meeting, Dr. Kazuo Sakai, Professor, Faculty of Nursing, Tokyo Healthcare University, Co-Chair), summarized the deliberation results from the three-day meeting. Dr. Curtis Harris, Chief, Laboratory of Human Carcinogenesis, and Head, National Cancer Institute, U.S. National Institute of Health, was on hand as the other SAC Co-chair.

Key SAC recommendations were explained at the press conference: The SAC indicated its desire to see continued progress in the work of cataloging and quality testing of biosamples, which continued in 2018 under the leadership of a new BRC Chief. Such work was based on last year’s SAC recommendations. Dr. Sakai also reiterated the point that, while animal studies cannot be directly linked to human data, such studies can be an important approach in mechanistic understanding of radiation effects in the children of directly exposed parents. The SAC expressed its desire for RERF’s newly established animal testing facilities to be used to the utmost.

In one of the major issues facing RERF, the SAC also hoped for RERF to recruit specialists, as well as new research staff for training, in the field of bioinformatics to engage in research utilizing RERF’s important biosamples.

Dr. Sakai reiterated his praise for the new Research Cluster System, given its effectiveness in transcending research-department boundaries and instead grouping research according to theme.

In closing, he announced the SAC’s expectations for RERF to continue its contributions to the health of humankind through its research activities.
