Study IDST000661
Study TitleCHOICE clinical weight loss study
Study TypeMS analysis
Study SummaryEvaluation of plasma samples from the CHOICE clinical weight loss study in which obese post menopausal breast cancer survivors lost >15% initial body weight following either a low carbohydrate or a low fat dietary pattern. These samples will be interrogated for changes in metabolic intermediates and lipid metabolites that may be indicative of changes in prognosis for long term survival following treatment for breast cancer. Samples will be subjected to LCMS and shotgun lipidomics. In parallel, plasma and mammary gland fat pad from an obese rat model for breast cancer in which rats were subjected to a parallel level of weight loss will also be interrogated using the same procedures in an effort to inform the interpretation of the clinical data.
