MetabolomicsDarutigenol alleviates colitis through Akkermansia muciniphila-driven intestinal proline synthesis

Background: Gut microbiota dysbiosis is a critical contributor to the pathogenesis and progression of inflammatory bowel disease (IBD). Darutigenol (DL), a natural compound has demonstrated significant anti-inflammatory activity, but its low oral bioavailability limits its application. However, t...

MetabolomicsGut Microbiota-Proline Axis Drives HFpEF Through Fibroblast Ferroptosis

Heart failure with preserved ejection fraction (HFpEF) is a complex cardiometabolic disorder closely associated with systemic metabolic dysregulation. In this study, plasma samples were collected from C57BL/6J mice subjected to a high-fat diet–induced HFpEF model, with or without intervention, an...

MetabolomicsDeletion of Gja1 in myocardium emerges ventricular arrhythmia and tachycardia by reprogramming proline metabolism
Connexin43 (Cx43) is the predominant connexin in working myocardium. Its expression decreases in various cardiovascular diseases, and accompanied by ventricular arrhythmias (VAs). However, molecular mechanisms underlying increased arrhythmogenesis remained unclear. Here we established iPSC-derived c...

MetabolomicsDarutigenol alleviates ulcerative colitis via promoting Akkermansia muciniphila-mediated proline synthesis
Gut microbiota dysbiosis is associated with the occurrence and development of inflammatory bowel disease (IBD). Darutigenol (DL) is a natural compound with limited oral bioavailability, but has shown promise in the treatment of ulcerative colitis (UC). However, the precise mechanisms underlying its ...

MetabolomicsMitochondrial NAD+ Deficiency in Vascular Smooth Muscle Impairs Collagen III Turnover to Trigger Aortic Disease

Aortic disease poses a significant mortality risk in adults, yet many of its underlying factors remain undiscovered. In this study, we identify mitochondrial NAD⁺ deficiency as a causal factor. Metabolomics analysis of 73 surgical aortic specimens revealed impaired NAD⁺ salvage and mitochondrial ...

TranscriptomicsEffect of L-Proline on mouse embryonic stem cells (ESCs)
We found that the non-essential amino acid L-Proline (L-Pro) acts as a signaling molecule that promotes the conversion of embryonic stem cells (ESCs) into mesenchymal-like, spindle-shaped, highly motile, invasive pluripotent stem cells. This embryonic stem cell-to-mesenchymal-like transition (esMT) ...

TranscriptomicsDynamic mRNA gene expression during a nutritional upshift from proline to glutamine
Dynamic mRNA gene expression from the wildtype YSBN6 during a nutritional upshift from proline to glutamine. Glutamine was added to yeast cells growing exponentially on proline as the sole nitrogen source. A sample was taken at steady-state 10 minutes before the shift, and then 3, 7, 10, 14, 24, 56 ...

TranscriptomicsRNA-Seq Profiling of a Defective Seed Coat Mutation in Glycine max Reveals Differential Expression of Proline Rich and Other Cell Wall Protein Transcripts
The plant cell wall performs a number of essential functions including providing shape to many different cell types and serving as a defense against potential pathogens. The net pattern mutation creates breaks in the seed coat of soybean (Glycine max) because of ruptured cell walls. Using RNA-Seq, w...
