Abstract

Hematopoietic stem cells (HSCs) maintain production of all functional blood cells and are located within the bone marrow. In pathological conditions, such as obesity or leukemia, changes in these cells contribute to disease pathophysiology. In this study, we examined the impact of metabolic modulation of stem and progenitor cells within the bone marrow during diet-induced obesity (DIO) and leukemia relapse. Avocatin B (Avo), an inhibitor of fatty acid oxidation (FAO), was provided in the diet and its impact on stem cells using two disease models was tested. In DIO, high fat diet(HFD)-induced alterations in HSC number and function were attenuated with Avo (HFD: 46.9% decrease compared to control; p < 0.001; whereas DIO + Avo: 58.8% recovery; p < 0.05). In leukemia relapse, dietary Avo delayed disease reoccurrence. Taken together, addition of Avo into the diet imparts protection in the bone marrow.

期刊介绍: This timely publication reports and reviews current findings on the effects of nutrition on the etiology, therapy, and prevention of cancer. Etiological issues include clinical and experimental research in nutrition, carcinogenesis, epidemiology, biochemistry, and molecular biology. Coverage of therapy focuses on research in clinical nutrition and oncology, dietetics, and bioengineering. Prevention approaches include public health recommendations, preventative medicine, behavior modification, education, functional foods, and agricultural and food production policies.
