MetabolomicsCardiac disruption of SDHAF4-mediated mitochondrial complex II assembly promotes dilated cardiomyopathy
Succinate dehydrogenase, which is known as mitochondrial complex II, has proven to be a fascinating machinery, attracting renewed and increased interest in its involvement in human diseases. Herein, we find that succinate dehydrogenase assembly factor 4 (SDHAF4) is downregulated in cardiac muscle in...

ProteomicsDeacetylation Induced Nuclear Condensation of HP1γ Promotes Multiple Myeloma Drug Resistance
Functional crosstalk between histone modifications and chromatin remodeling has emerged as a key regulatory mode of transcriptional control during drug resistance, but the underlying mechanisms are not fully understood. Here we demonstrate that different proteins and their acetylation modification r...

ProteomicsCharacterization of kidney-specific and site-specific N-glycosylation signatures of isolated uromodulin from human urine
Uromodulin (Umod, Tamm–Horsfall protein), as the most abundant urinary N-glycoprotein exclusively produced by the kidney, can form filaments to antagonize the adhesion of uropathogens. However, the kidney-specific and site-specific N-glycosylation signatures of this glycoprotein remain poorly unders...

ProteomicsAMPK targets PDZD8 to promote carbon source shift to glutamine
This project contains the raw MS data that identified PDZD8 as a substrate of AMPK on the MAM of ER-mitochondria contact. They also revealed that site T527 is an AMPK-phosphorylation site.

ProteomicsLow-dose metformin targets the lysosome-AMPK pathway through PEN2
Metformin is the most prescribed anti-diabetic medicine, and has also been shown to have other various benefits, such as anti-aging and anti-cancer effects. For clinical doses of metformin, it is known that AMPK plays a major role; however, the direct molecular target of metformin remains unclear. H...

ProteomicsThe aldolase inhibitor aldometanib mimics glucose starvation to activate lysosomal AMPK
The activity of 5’-adenosine monophosphate-activated protein kinase (AMPK) is inversely correlated with the cellular availability of glucose. When glucose levels are low, the glycolytic enzyme aldolase is not bound to fructose-1,6-bisphosphate (FBP) and, instead, signals to activate lysosomal AMPK. ...

ProteomicsLithocholic acid targets TULP3-Sirtuins to deacetylate v-ATPase and activate AMPK
Lithocholic acid (LCA), accumulated in mammals during calorie restriction (CR), can activate AMP-activated protein kinase (AMPK) and slow down ageing1. However, how LCA is signalled to activate AMPK and elicit the biological effects is unclear. Here, we show that LCA can enhance the activity of sirt...
