Precision UV-B irradiation for flavonoid biofortification in indoor-cultivated Morus nigra: Integrated multi-omics and molecular docking insights.

Precision application of UV irradiation represents an effective strategy for improving the quality of functional food crops under controlled environmental conditions. Morus nigra serves as a significant functional food resource in Xinjiang, with its leaves being rich in diverse bioactive compounds with nutritional and health-promoting properties. In this study, a low-dose UV-B treatment regimen was developed to enhance flavonoids in indoor-cultivated M. nigra without growth penalty. Multi-omics revealed a hormone shift (suppressed auxin vs. activated JA signaling). This triggered transcriptional reprogramming of PAL/4CL and CHS/CYP75B1, redirecting carbon flux towards flavonoid biosynthesis. Transient overexpression of MYB, NAC, and TIFY variants validated this regulatory network. The UV-B-induced NAC upregulated key genes and flavonoids, while different TIFY members showed diverse regulatory effects. Molecular docking predicted that the induced flavonoids had hypoglycemic, antioxidant, and anti-browning potential. This study indicates targeted UV-B as a green biofortification strategy for high-value crops in controlled environments.

[Morphological changes in the endocrine pancreas of the rabbit after the administration of a Morus alba extract].

The authors examined the effect of an extract, obtained from the leaves of the plant Morus alba on beta-cells of the endocrine pancreas of a rabbit after subcutaneous and parenteral administration. The most manifested morphologic changes were observed after subcutaneous administration under the conditions of a chronic experiment. There were degranulation of beta-cells of the Langerhans islets of these animals developed at various degree and discovered by means of a light and electrone microscope.

In silico screening of anti-atherosclerotic compounds from Morus alba leaves by machine learning and network pharmacology.

OBJECTIVE: This study integrates machine learning with network pharmacology, molecular docking, and molecular dynamics simulations to screen bioactive compounds from Mulberry leaves and elucidate their potential mechanisms against atherosclerosis (AS). METHODS: A training dataset of anti-AS active compounds was compiled and encoded as Morgan fingerprints. Three machine learning classifiers, specifically Random Forest (RF), Support Vector Machine (SVM), and Extreme Gradient Boosting (XG-Boost), were constructed and evaluated using multiple performance metrics. Potential active components from Mulberry leaves and AS-related targets were retrieved, followed by protein-protein interaction network construction and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Molecular docking was then performed to evaluate binding affinities between core targets and candidate compounds, and the most stable complex was subjected to molecular dynamics simulations using GROMACS (2025). RESULTS: The RF model achieved superior performance (accuracy= 0.8354, F1 = 0.8408, AUC = 0.9119) with 100% external validation accuracy. Thirteen anti-AS candidates were prioritized from mulberry leaves, four of which have been previously documented. Network pharmacology revealed AKT1 and IL6 as core targets, enriched in pathways such as endocrine resistance. Molecular docking and dynamics simulations confirmed strong binding between oxysanguinarine and AKT1, with the complex exhibiting high stability. CONCLUSION: The RF model provides a reliable computational tool for prioritizing anti-AS compounds from Mulberry leaves. The integrated analysis reveals that Mulberry leaves exert anti-atherosclerotic effects through multi-target (e.g., AKT1, IL6) and multi-pathway (e.g., PI3K-Akt) mechanisms, offering a framework for further experimental validation.

Pharmacological studies on root bark of mulberry tree (Morus alba L.)

Pharmacological studies were done on the root bark of mulberry tree and pharmacological effects were compared with the clinical effects of "Sohakuhi" in Chinese medicine. n-Butanol- and water-soluble fractions of mulberry root had similar effects except for those on the cadiovascular system. Both fractions showed cathartic, analgesic, diuretic, antitussive, antiedema, sedative, anticonvulsant, and hypotensive actions in mice, rats, guinea pigs and dogs. There appears to be a correlation between the experimental pharmacological results and the clinical applications of mulberry root found in the literature on Chinese medicine.

Exploring the therapeutic potential of extract in targeting localized adiposity.

OBJECTIVE: To determine direct targeting of localized adiposity through Morus alba Linne bark injection based on pharmacology network analysis. METHODS: Male C57BL/6J mice were fed a high-fat diet (HFD) to induce obesity. After 6 weeks on HFD, the water extract of Morus alba L.bark (MAB, 2 mg/mL) was locally injected into one inguinal fat pad, while saline was injected into the other side, 3 times/week for 6 weeks (n = 6/group). The water extract of MAB was freeze-dried and then diluted in saline before use. RESULTS: HFD-fed mice treated with local MAB topical injection showed reduced adipocyte weight and size in inguinal fat pads by dual-energy X-ray absorptiometry. No toxicity changes seen in liver, spleen, kidney tissue, or alanine aminotransferase / aspartate aminotransferase levels in serum by MAB injection. Protein levels of phosphorylated insulin receptor substrate-1 and glucose transporter type 4, and mRNA expression of adiponectin, were increased in inguinal adipose tissue injected with MAB locally. Locally MAB injection led to a decrease in glucose-6-phosphatase and phosphoenolpyruvate carboxykinase, linked to gluconeogenesis, while forkhead box protein O1, which regulates these factors, was increased. Moreover, there was an increase in adenosine 5'-monophosphate-activated protein kinase, related to lipogenesis, as well as elevated levels of hormone-sensitive lipase and fatty acid synthase, both associated with lipolysis. These results support the 'insulin signaling pathway' and 'regulation of lipolysis in adipocytes' identified in the Kyoto Encyclopedia of Genes and Genomes pathway through network analysis. CONCLUSION: This study suggests that MAB topical injection exhibits localized fat reduction by inhibiting insulin resistance, gluconeogenesis and lipogenesis mediator, while activating lipolysis enzymes within targeted adipose site.
