AI Article Synopsis

  • Taraxacum mongolicum is a traditional Chinese medicine known for its use in treating inflammatory and infectious diseases, including mastitis, but its mechanisms of action remain unclear.
  • The study aimed to uncover the protective effects and mechanisms of T. mongolicum against mastitis caused by Staphylococcus aureus in mice.
  • Results showed that T. mongolicum reduced inflammatory cytokines, improved tissue health, and inhibited specific signaling pathways linked to inflammation, suggesting its potential as a treatment for mastitis.

Article Abstract

Ethnopharmacological Relevance: As a traditional Chinese medicine, Taraxacum mongolicum has been widely used for the prevention and treatment of a variety of inflammatory and infectious diseases, and also clinically used as a remedy for mastitis. However, the scientific rationale and mechanism behind its use on mastitis in vivo are still unclear.

Aim Of The Study: This study aimed to investigate the protective effect and potential mechanism of Taraxacum mongolicum Hand.-Mazz. (T. mongolicum) on mastitis infected by Staphylococcus aureus (S. aureus).

Materials And Methods: Female ICR mice were given intragastrically 2.5, 5 and 10 g/kg of T. mongolicum extract twice per day for 6 consecutive days, and infected with S. aureus via teat canal to induce mastitis. Pro-inflammatory cytokine tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) levels were determined by ELISA. Myeloperoxidase (MPO) activity and distribution were measured by reagent kit and immunohistochemistry. Histopathological changes of mammary gland tissues were observed by H&E staining. Toll-like receptor 2 (TLR2) expression, phosphorylations of related proteins in nuclear factor-kappa B (NF-κB) and mitogen-activated protein kinases (MAPKs) signaling pathways were detected by western blot.

Results: T. mongolicum decreased TNF-α, IL-6 and IL-1β levels, and reduced MPO activity and distribution in sera and mammary glands with S. aureus-infected mastitis. In addition, T. mongolicum effectively attenuated histopathological damages and cell necrosis of mammary gland tissues infected by S. aureus. Moreover, T. mongolicum inhibited the expression of TLR2, and the phosphorylations of inhibitor κBα (IκBα), p65, p38, extracellular signal-regulated kinase 1/2 (ERK1/2) and c-Jun N-terminal kinase (JNK) proteins in mammary glands with S. aureus-infected mastitis.

Conclusions: This study suggests that T. mongolicum protects against S. aureus-infected mastitis by exerting anti-inflammatory role, which is attributed to the inhibition of TLR2-NF-κB/MAPKs pathways.

Background: Pancreatic cancer (PC) is a malignant tumor with complex development mechanisms and a poor prognosis. Taraxasterol (TAX), a pentacyclic triterpenoid plant sterol derived from Taraxacum mongolicum, has multiple biological activities including an anti-tumor effect. However, the mechanism by which TAX exerts its anticancer effects in PC remains unclear.

Chicoric acid, a phenolic compound derived from plants, exhibits a range of pharmacological activities. Light significantly influences the chicoric acid biosynthesis in Taraxacum mongolicum; however, the transcriptional regulatory network governing this process remains unclear. A combined analysis of the metabolome and transcriptome revealed that blue light markedly enhances chicoric acid accumulation compared to red light.

Introduction: Dandelion is widely used in clinical practice due to its beneficial effects. Polyphenolic compounds are considered the main anti-inflammatory active ingredient of dandelion, but the gene expression patterns of polyphenolic compounds in different dandelion tissues are still unclear.

Methods: In this study, we combined a nontargeted metabolome, PacBio Iso-seq transcriptome, and Illumina RNA-seq transcriptome to investigate the relationship between polyphenols and gene expression in roots, flowers, and leaves of flowering dandelion plants.
