Membrane-localized transporters constitute important components for specialized metabolism in plants. However, due to the vast array of specialized metabolites produced by plants, and the large families of transporter genes, knowledge about the intracellular and intercellular transport of plant metabolites is still in its infancy. Cucurbitacins are bitter and defensive triterpenoids produced mainly in the cucurbits. Using a comparative genomics and multi-omics approach, a MATE gene (CsMATE1), physically clustered with cucurbitacin C (CuC) biosynthetic genes, was identified and functionally shown to sequester CuC in cucumber leaf mesophyll cells. Notably, the CuC transport process is strictly co-regulated with CuC biosynthesis. CsMATE1 clustering with bitterness biosynthesis genes may provide benefits and a basis for this feedback regulation on CuC sequestration and biosynthesis. Identification of transport systems for plant-specialized metabolites can accelerate the metabolic engineering of high-value-added compounds by simplifying their purification process.

Plant metabolites known as cucurbitacins are known to impart an unpleasant bitter taste to edible fruits and even lead to severe health complications after the ingestion of relatively high amounts. In this study, an analytical method based on reversed phase liquid chromatography with combined detection by UV spectroscopy and atmospheric pressure chemical ionization high-resolution single/tandem mass spectrometry was applied to confirm the occurrence of four cucurbitacins (B, D, and R, and 23,24-dihydro cucurbitacin B) previously inferred in unexpectedly bitter-tasting fruits of an Italian variety (Scopatizzo) of unripe melon (Cucumis melo L.), known for the sweetness of its fruits.

Cerebral malaria (CM) is a fatal complication of Plasmodium falciparum infection. The biological and physiological links between CM, inflammation, and inflammasome, point to the complexity of its pathology. Resistance to available and affordable drugs, worsening economic crisis, and urgent need for integration of orthodox with traditional/alternative medicine, actualized the search for sustainable pharmacotherapy.

In this study, three fermentation treatments of spontaneous fermentation (SF), direct inoculation of CECA (YF), and inoculation with CECA after addition of dimethyl dicarbonate (YDF) were carried out. Multivariate statistical analysis approved that CECA inoculation significantly influenced the composition of 141 metabolites (15 volatile organic compounds (VOCs) and 126 non-VOCs), mainly consisting of 36 acids and derivatives and 25 lipids and lipid-like molecules. YF and YDF wines exhibited similar correlations with aroma types, while there were differences in the kinds and number of VOCs.

Background: Bone remodeling is a critical process that maintains skeletal integrity, orchestrated by the balanced activities of osteoclasts, which resorb bone, and osteoblasts, which form bone. Osteoclastogenesis, the formation of osteoclasts, is primarily driven by NFATc1, a process activated through c-Fos and NF-κB signaling pathways in response to receptor activator of nuclear factor κB ligand (RANKL). Dysregulation of RANKL signaling is a key contributor to pathological bone loss, as seen in conditions such as osteoporosis.

One of the hallmarks of cancer is metabolic reprogramming which controls cellular homeostasis and therapy resistance. Here, we investigated the effect of momordicine-I (M-I), a key bioactive compound from Momordica charantia (bitter melon), on metabolic pathways in human head and neck cancer (HNC) cells and a mouse HNC tumorigenicity model. We found that M-I treatment on HNC cells significantly reduced the expression of key glycolytic molecules, SLC2A1 (GLUT-1), HK1, PFKP, PDK3, PKM, and LDHA at the mRNA and protein levels.
