MetabolomicsSerine synthesis pathway enzyme PHGDH is critical for muscle cell biomass, anabolic metabolism and mTORC1 signaling

Cells use glycolytic intermediates for anabolism e.g., via the serine synthesis and pentose phosphate pathways. However, we still understand poorly how these metabolic pathways contribute to skeletal muscle cell biomass generation. The first aim of this study was therefore to identify enzymes tha...

MetabolomicsImpaired Glycolysis-Derived Serine Metabolism as a Key Driver of Podocyte Injury with Senescence

Chronic kidney disease (CKD) is a major health issue, with podocyte injury with senescence playing a central role in glomerulosclerosis. This study investigates the link between glycolysis-derived serine metabolism and podocyte injury with senescence, focusing on the role of phosphoglycerate kina...

MetabolomicsSerine Metabolism Tunes Immune Responses To Promote Oreochromis niloticus Survival upon Edwardsiella tarda Infection
Overactive immune response is a critical factor triggering host death upon bacterial infection. However, the mechanism behind the regulation of excessive immune responses is still largely unknown, and the corresponding control and preventive measures are also to be explored. In this study, we find t...

TranscriptomicsTranscription profiling of E. coli MG1655 treated with serine hydroxamate
For over 30 years, serine hydroxamate has been used to chemically stimulate a stringent response in Escherichia coli and other bacteria. These studies have elucidated numerous characteristics of the classical stringent response beyond the simple cellular response to an amino acid shortage, including...

MetabolomicsThe oncoprotein SET promotes serine-derived one-carbon metabolism by regulating SHMT2 enzymatic activity
Cancer cells frequently reprogram one-carbon metabolic pathways to fulfill their vigorous demands of biosynthesis and antioxidant defense for survival and proliferation. Dysfunction of oncogenes or tumor suppressor genes is critically involved in this process, but the precise mechanisms by which can...

MetabolomicsMicroglia contributes to bipolar depression through Serinc2-dependent phospholipid synthesis

Although clinical research has revealed microglia-related inflammatory and immune responses in bipolar disorder (BD) patient brains, it remains unclear how microglia contribute to the pathogenesis of BD. Here, we demonstrated that Serinc2 is associated with susceptibility to BD and showed a reduc...

MetabolomicsOxygen-induced pathological angiogenesis promotes intense lipid synthesis and remodeling in the retina

The retina is a notable tissue with high metabolic needs which relies on specialized vascular networks to protect the neural retina while maintaining constant supplies of oxygen, nutrients and dietary essential fatty acids. Here we analyzed the lipidome of the mouse retina under healthy and patho...

MetabolomicsGDF15 hijacks B cells to fuel the lifeblood of tumor salvage pyrimidine synthesis
B cell-tumor crosstalk has emerged as a critical determinant of tumor progression; however, its role in metabolic reprogramming and therapeutic resistance remains poorly understood. Here, we uncover a metabolic feedback loop that drives resistance to dihydroorotate dehydrogenase (DHODH) inhibitors. ...

ProteomicsPHGDH Arginine Methylation by PRMT1 Promotes Serine Synthesis and Represents a Therapeutic Vulnerability in Hepatocellular Carcinoma
Serine synthesis is crucial for tumor growth and survival, but its regulatory mechanism in cancer remains elusive. Here, we found that R236 methylation of PHGDH promotes its activity and stimulates serine synthesis in hepatocellular carcinoma.

ProteomicsPHGDH Arginine Methylation by PRMT1 Promotes Serine Synthesis and HCC Growth
Serine synthesis is crucial for tumor growth and survival, but its regulatory mechanism in cancer remains elusive. Phosphoglycerate dehydrogenase (PHGDH) is the first rate-limiting enzyme in serine biosynthesis pathway. Here, we analyzed immunoprecipitated PHGDH from human HEK293T cells by liquid ch...
