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...

MetabolomicsDifferent regions of synaptic vesicle membrane regulate VAMP2 conformation for the SNARE assembly
Vesicle associated membrane protein 2 (VAMP2/synaptobrevin2), a core SNARE protein residing on synaptic vesicles (SVs), forms helix bundles with syntaxin-1 and SNAP25 for the SNARE assembly. Prior to the SNARE assembly, the structure of VAMP2 is unclear. Here, by using in-cell NMR spectroscopy, we d...

MetabolomicsTFAM loss induces nuclear actin assembly upon mDia2 malonylation to promote liver cancer metastasis
The mechanisms underlying cancer metastasis remain poorly understood. Here, we report that TFAM deficiency rapidly and stably induced spontaneous lung metastasis in mice with liver cancer. Interestingly, unexpected polymerization of nuclear actin was observed in TFAM-knockdown HCC cells when cytoske...

MetabolomicsGeneration of a chromosome-scale genome assembly of the insect-repellent terpenoid-producing Lamiaceae species, Callicarpa americana

BACKGROUND: Plants exhibit wide chemical diversity due to the production of specialized metabolites that function as pollinator attractants, defensive compounds, and signaling molecules. Lamiaceae (mints) are known for their chemodiversity and have been cultivated for use as culi...

MetabolomicsTEX44 CPT1B Axis Regulates Mitochondrial Sheath Assembly and Fatty Acid Oxidation in Sperm
Mitochondrial fatty acid β-oxidation (FAO) is essential for energy production and cellular homeostasis, yet its specific role in sperm function has remained unclear. Through whole-exome sequencing of 673 patients with asthenozoospermia, we identified biallelic TEX44 variants in six individuals, all ...

MetabolomicsTEX44 CPT1B Axis Regulates Mitochondrial Sheath Assembly and Fatty Acid Oxidation in Sperm

Mitochondrial fatty acid β-oxidation (FAO) is essential for energy production and cellular homeostasis, yet its specific role in sperm function has remained unclear. Through whole-exome sequencing of 673800 patients with asthenozoospermia, we identified biallelic TEX44 variants in six individuals...

MetabolomicsChilling-induced restructuring of seed-borne endophytes enhances early cold tolerance and microbiome assembly in common vetch
Chilling stress constitutes a major abiotic constraint on plant growth and productivity. Although plants mobilize well-characterized physiological and transcriptional acclimation mechanisms, the integrative roles of root-associated microbiomes and root exudate chemistry in chilling tolerance, partic...

MetabolomicsA chromosome-level genome assembly and multi-omics analyses provide insights into the biosynthesis of piperlongumine in Piper sarmentosum

Piper sarmentosum Roxb. is a significant medicinal and edible plant, and its active compound piperlongumine (PL) has garnered attention due to its pharmacological activities, including anticancer and anti-inflammatory effects. However, the key enzymes and regulatory mechanisms of its biosynt...

Metabolomics3,4-Dihydroxybenzaldehyde exerts anti-Alzheimer's effects by inhibiting Aβ protofibril assembly and activating antioxidant defense mechanisms

Broad-spectrum metabolomic analyses reveal that DBD markedly modulates the nematode’s metabolic profile. DBD enhances the activation of transcription factors DAF-16/FOXO and SKN-1/Nrf2, increasing resistance to oxidative and thermal stress. These findings suggest that DBD possesses multi-target t...

ProteomicsThe assembly of the photosystem II intermediate RC47 in plants involves the cooperation of the eukaryotic factor DEAP2 with PAM68The assembly of the photosystem II intermediate RC47 in plants involves the cooperation of the eukaryotic factor DEAP2 with PAM68
The initial step of oxygenic photosynthesis is the thermodynamically challenging extraction of electrons from water and release of molecular oxygen. This light-driven process, which allows for the life on Earth as we know it, is catalyzed by photosystem (PS) II in the thylakoid membrane of photosynt...
