Lipoxin A4 (LXA4) promotes the browning of white adipose and energy consumption. The specific mechanism of which involved in white adipose browning is less clear. A high-fat diet (HFD) mouse model was constructed. Different groups of mice were treated with LXA4 accordingly. The body weight of mouse, subcutaneous and visceral fat, and food intake were recorded. The effect of LXA4 was examined by observing changes in pathology, serum insulin and lipid accumulation indices. The effects of LXA4/miR-133a-3p/Sirtuin1 on lipid droplet formation, fat browning-related genes, and the insulin receptor-AKT pathway in cells were examined after induction of adipocyte differentiation in 3T3-L1 precursors. At the cellular level, LXA4 promoted lipid droplet formation, expressions of fat browning genes and activation of the insulin receptor-AKT pathway in differentiated 3T3-L1 cells. MiR-133a-3p agomir partially offset the effects of LXA4. SIRT1 was a downstream target gene of miR-133a-3p, participating in the promotive effects of LXA4 on fat browning. LXA4 promotes white adipose browning and relieves insulin resistance through miR-133a-3p/SIRT1 pathway.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
