  • Ginsenoside compound K (GCK) has a significant hypoglycemic effect related to gut microbiota, but its precise mechanisms, especially in high-fat-diet-induced type 2 diabetes (T2D), are not well understood.
  • The study involved creating a diabetic mouse model and conducting fecal microbiota transplantation to explore GCK's role in regulating blood sugar levels.
  • Results indicated that GCK improved metabolic disorders and changed gut microbiota, leading to increased levels of N-acetylserotonin (NAS) and glucagon-like peptide-1 (GLP-1), thereby enhancing insulin sensitivity in the diabetic mice.

Berberine is an effective antimicrobial and antidiabetic alkaloid, primarily extracted from divergent botanical lineages, specifically (Ranunculales, early-diverging eudicot) and (Sapindales, core eudicot). In comparison with its known pathway in species, its biosynthesis in species remains elusive. Using chromosome-level genome assembly, coexpression matrix, and biochemical assays, we identified six key steps in berberine biosynthesis from , including methylation, hydroxylation, and berberine bridge formation.

Long non-coding RNAs (lncRNAs) are crucial in regulating secondary metabolite production in plants, but their role in artemisinin (ART) biosynthesis, a key anti-malarial compound from Artemisia annua, remains unclear. Here, by investigating high-artemisinin-producing (HAP) and lowartemisinin-producing (LAP) genotypes, we found that the final artemisinin content in is influenced by the quantity of the precursor compounds. We report on RNA deep sequencing in HAP and LAP genotypes.

Article Synopsis
  • - Seasonal influenza is a major public health concern, making the development of effective treatments like Baloxavir, a PA protein inhibitor, essential for fighting influenza A and B viruses.
  • - Researchers optimized the structure of Baloxavir, leading to the creation of new compounds, ATV03 and ATV07, which exhibited strong anti-influenza activity, metabolic stability, and favorable bioavailability.
  • - Because of its improved effectiveness and stability, ATV03 was chosen for further studies as a promising candidate for tackling both seasonal and pandemic influenza strains.

Polarization imaging has achieved a wide range of applications in military and civilian fields such as camouflage detection and autonomous driving. However, when the imaging environment involves a low-light condition, the number of photons is low and the photon transmittance of the conventional Division-of-Focal-Plane (DoFP) structure is small. Therefore, the traditional demosaicing methods are often used to deal with the serious noise and distortion generated by polarization demosaicing in low-light environment.

(saffron) is a globally autumn-flowering plant, and its stigmas are the most expensive spice and valuable herb medicine. specialized metabolites, crocins, are biosynthesized in distant species, (eudicot) and (monocot), and the evolution of crocin biosynthesis remains poorly understood. With the chromosome-level genome assembly, we revealed that two rounds of lineage-specific whole genome triplication occurred, contributing important roles in the production of carotenoids and apocarotenoids.

Fungal identification is a cornerstone of fungal research, yet traditional molecular methods struggle with rapid and accurate identification, especially for closely related species. To tackle this challenge, we introduce a universal identification method called Analysis of whole GEnome (AGE). AGE includes two key steps: bioinformatics analysis and experimental practice.

Menispermaceae species, as early-diverging eudicots, can synthesize valuable benzylisoquinoline alkaloids (BIAs) like bisbenzylisoquinoline alkaloids (bisBIAs) and sinomenines with a wide range of structural diversity. However, the evolutionary mechanisms responsible for their chemo-diversity are not well understood. Here, a chromosome-level genome assembly of Menispermum dauricum is presented and demonstrated the occurrence of two whole genome duplication (WGD) events that are shared by Ranunculales and specific to Menispermum, providing a model for understanding chromosomal evolution in early-diverging eudicots.

Survival crises stalk many animals, especially endangered and rare animals. Accurate species identification plays a pivotal role in animal resource conservation. In this study, we developed an animal species identification method called Analysis of whole-GEnome (AGE), which identifies species by finding species-specific sequences through bioinformatics analysis of the whole genome and subsequently recognizing these sequences using experimental technologies.

The challenge of discriminating closely related species persists, notably within clinical diagnostic laboratories for invasive aspergillosis (IA)-related species and food contamination microorganisms with toxin-producing potential. We employed Analysis of the whole-GEnome (AGE) to address the challenges of closely related species within the genus and developed a rapid detection method. First, reliable whole genome data for 77 species were downloaded from the database, and through bioinformatic analysis, specific targets for each species were identified.

Crocins are important natural products predominantly obtained from the stigma of saffron, and that can be utilized as a medicinal compound, spice, and colorant with significant promise in the pharmaceutical, food, and cosmetic industries. Carotenoid cleavage dioxygenase 2 (CCD2) is a crucial limiting enzyme that has been reported to be responsible for the cleavage of zeaxanthin in the crocin biosynthetic pathway. However, the catalytic activity of CCD2 on β-carotene/lycopene remains elusive, and the soluble expression of CCD2 remains a big challenge.

Chlorohydrins and oxaheterocycles are synthetically valuable building blocks for diverse natural products and therapeutic substances. A highly efficient Ir/-phamidol-catalyzed asymmetric hydrogenation of ω-chloroketones was successfully developed, and various chlorohydrins and oxaheterocycles were obtained divergently with excellent yields and enantioselectivities (up to >99% yield and >99% ee). Synthetic utilities of this divergent transformation were demonstrated by gram-scale synthesis of key intermediates of several enantiomerically enriched drugs via this catalytic methodology.
