Breast cancer is the leading cancer, accounting for approximately 15% cancer deaths in women worldwide. This study investigated the anti-inflammation and anticancer properties of two bioactive components from Antrodia camphorata(AC), a rare medicinal mushroom natively grown in Taiwan and commonly used in Chinese traditional medicine. The anti-inflammatory and antitumorigenic functions of Antroquinonol (AQ) and 4-Acetylantroquinonol B (4-AAQB) from AC were examined on breast cancer cell line MCF-7 with/without TNF-[Formula: see text] stimulation. ⋯ For Wnt/[Formula: see text]- catenin signaling downstream genes (CCND1, C-MYC and AXIN2), both components have significant or marginal inhibitory effect on C-MYC in the condition with/without TNF-[Formula: see text] stimulation. The luciferase assay demonstrated that both components exhibited inhibitory effect on NF-[Formula: see text]B signaling and Wnt/[Formula: see text]-catenin signaling in the condition without TNF-[Formula: see text] stimulation. In conclusion, our results displayed an overall pattern that AQ and 4-AAQB possess potential anti-inflammatory and antitumorigenic functions in MCF-7 breast cancer cells and warranted further in vivo pre-clinical and clinical studies to explore their anticancer properties.

Citri Reticulatae Pericarpium (CRP), also known as Chenpi in Chinese, is the dry mature peel of Citrus reticulata Blanco or its cultivated varieties. CRP as the health-care food and dietary supplement has been widely used in various diseases. However, the potential pharmacological mechanisms of CRP to predict and treat various diseases have not yet been fully elucidated. ⋯ The 121 targets are closely related to various diseases of the cardiovascular system, respiratory system, gastrointestinal system, etc. These targets are further mapped to compound-target, target-disease, and target-pathway networks to clarify the therapeutic mechanism of CRP at the system level. The current study sheds light on a promising way for promoting the discovery of new botanical drugs.

Acupuncture is a therapeutic treatment that is well recognized in many countries. However, the initiation mechanisms of acupuncture are not well understood. Purinergic signaling has been considered a key signaling pathway in acupuncture in recent years. ⋯ ATP also promotes the proliferation of immune cells through P2 receptors and A3 receptors, causing inflammation. In contrast, adenosine activates A2 receptors, promotes the production and infiltration of immunosuppressive cells, and causes an anti-inflammatory response. In summary, we described the role of purinergic signaling as a general signaling pathway in the initiation of acupuncture and the influence of purinergic signaling on the neuroimmune network to lay the foundation for future systematic research on the mechanisms of acupuncture therapeutics.

The incidence of diabetes worldwide continues to rise, placing a huge economic and medical burden on human society. More than 90% of diabetic cases are type 2 diabetes (T2D). At present, the pathogenesis of T2D is not yet fully understood. ⋯ Traditional Chinese Medicine (TCM) presents unique advantages in the treatment of T2D. Multiple metabolites and metabolic pathways have been identified in the treatment of TCM, providing valuable biomarkers and novel targets for drug therapy and pharmacological mechanism. Therefore, this paper reviews the modern achievements of metabolomics in T2D research and the progress of TCM management in recent years, in order to provide valuable information for related research.

Mistletoe extracts (Viscum album L.) have been widely used as complementary and alternative medicines for the treatment of cancer, and their cytotoxic effects have been reported on various types of cancer. However, the molecular targets of mistletoe extracts have not been well studied. Herein, we investigated molecules associated with the in vitro and in vivo anticancer effects of mistletoe extract using 4T1 murine breast cancer cells. ⋯ Furthermore, mistletoe extract effectively suppressed tumor growth in 4T1 tumor-bearing BALB/c mice. In addition to tumor growth inhibition, mistletoe extract inhibited lung metastasis in the tumor-bearing mice and cell invasiveness by downregulating the expressions of matrix metalloproteinases (MMPs), urokinase-type plasminogen activator (uPA), uPA receptor, and markers of epithelial-mesenchymal transition (snail and fibronectin). Taken together, our results suggest that mistletoe extract targets the STAT3-FOXM1 pathway for its cytotoxic effects, and that mistletoe extracts might be useful for the treatment of patients with cancers highly expressing the STAT3-FOXM1 pathway.
