Study ID	ST002989
Study Title	Targeting NPM1 Epigenetically Promotes Post-infarction Cardiac Repair by Reprogramming Reparative Macrophage Metabolism
Study Summary	Reparative macrophages play a crucial role in limiting excessive fibrosis and promoting cardiac repair after myocardial infarction (MI), highlighting the significance of enhancing their reparative phenotype for wound healing. Metabolic adaptation orchestrates the phenotypic transition of macrophages; however, the precise mechanisms governing metabolic reprogramming of cardiac reparative macrophages remain poorly understood. In this study, we investigated the role of Nucleophosmin 1 (NPM1) in the metabolic and phenotypic shift of cardiac macrophages in the context of MI, and explored the effect of targeting NPM1 for ischemic tissue repair.

Sample Preparation:

Sampleprep ID:	SP003108
Sampleprep Summary:	For each sample, 500 μl precooled MeOH/H2O (3/1, v/v) was added in. The samples were then vortexed for 30 sec. After precooling in dry ice, the samples were frozen and thawed three times in liquid nitrogen. They were then vortexed for 30 sec and sonicated for 15 min in an ice-water bath. Next, as a subsequent step, the samples were incubated at -40 °C for 1 h and centrifuged at 12000 rpm for 15 min at 4 °C (RCF = 13800 g, R = 8.6 cm). Afterwards, an aliquot of 400 μl of clear supernatant was collected and dried by spinning. As a reconstitution solution, mix 200 ml of ultrapure water with the residue. The reconstituted samples were vortexed before passing through the filter of the centrifuge tube, after which they were transferred to inserts in injection vials for HPLC-MS/MS analysis.
