miR-550-1 functions as a tumor suppressor in acute myeloid leukemia via the hippo signaling pathway

open access: yesInternational Journal on Biological Sciences, 2020
MicroRNAs (miRNAs) and N6-methyladenosine (m6A) are known to serve as key regulators of acute myeloid leukemia (AML). Our previous microarray analysis indicated miR-550-1 was significantly downregulated in AML.

Aberrant bone marrow-derived microglia in the hypothalamus may dysregulate appetite in diabetes [PDF]

open access: yes, 2023
Bone marrow derived cells (BMDCs) migrate into the hypothalamus, where those cells give rise to microglia to regulate food intake. Given the fact that diabetes functionally impairs BMDCs, we hypothesized that diabetic microglia would fail to exhibit ...
