1. ToMMo Birth and Three Generation Cohort Study
Though this cohort project, we have started multi-omics analysis to clarify pathophysiology of perinatal disorders. Particularly, genetic analysis with family tree genomic information would be powerful tools to elucidate undetermined mechanisms of maternal-fetal disorders.
2. Early Prediction by Bioinformatics for Pregnancy Related Disorders
In the MLOG (Maternity Life Log) project, participants will collect daily health parameters, such as body weight, duration of sleep, activity amount, blood pressure and body temperature using health care devices. With the multilayer integration of these life log information, lifestyle habits and omics analysis, we try to establish mobile healthcare programs for the prediction of pregnancy related disorders, including pregnancy induced hypertension, gestational diabetes and premature labor. MLOG project is the collaborative research with NTT DOCOMO with a widely accepted commercial service of mobile health service in Japan.
3. Establishment of Biomarkers for the diagnosis of feto-maternal disorders.
Using newly developed in silico technology, variety of omics analysis by the project team with multiple laboratories are in progress. These studies would reveal new biomarkers for the early prediction of perinatal disease (e.g. preeclampsia). Development of clinical diagnostic systems for personalized prevention would be strongly expected.
