Figure 1. Graphical Abstract of the Paper (image) Kanazawa University Share Print E-Mail Caption Spred1 maintains hematopoietic homeostasis by controlling both of HSC self-renewal supported by ROCK activity and tumor suppression due to inactivation of ERK signaling. Spred1 deficiency under high-fat diet condition induces the activation of ERK signaling, resulting in functional HSC failure, severe anemia, and development of leukemia. The hematopoietic abnormalities are mediated by the gut microbiota dysbiosis. Credit Kanazawa University Usage Restrictions The image may only be used with appropriate caption and credit.
