Abstract Systems biology is an approach that employs modern biological techniques and methods to combine the overall regulation of the body by Chinese herbal formulas with systems analysis at the molecular level. In this study, the underlying immunomodulatory mechanisms of yupingfeng granules (YPFG) were investigated based on the integration of metabolomics and network pharmacology methods. Selected routine peripheral blood indicators, body weight, and organ indices related to immunity were firstly measured in order to evaluate the effects of YPFG in cyclophosphamide-induced immunocompromised rats. Plasma metabolomics analyses were carried out by UPLC-Q-TOF-MS combined with a multivariate data analysis. Our study indicates that the potential regulatory mechanism was related to bile acid and glycerophospholipid metabolism, involving the regulation of 11 metabolites, including 8 bile acids, 1 phosphatidylserine, and 2 phosphatidylethanolamines. By means of network pharmacology, the compound-target network between potential active components of YPFG and immune dysregulation was constructed, which releated to estrogen receptor, PPAR, MAPK, PI3K-Akt, JNK signaling pathways, and ubiquitin-mediated protein degradation. The immunomodulatory effect of YPFG may be exerted through regulating lipid metabolism, then bile acid metabolism and inflammation were affected. Biological verification was also performed on cyclophosphamide-induced immunocompromised BALB/c mice. Flavonoid and saponin, two types of compounds in YPFG, were found to be the major active ingredients in the immunomodulatory effects of YPFG, and these components may regulate the abnormal metabolism of bile acids by enhancing the expression of FXR and LXRα. This work elucidated active ingredients, potential biomarkers, and mechanisms of action in the immunoregulatory effects of YPFG from the perspective of systems biology, which provides a scientific basis for its precise clinical medication.

Abstract Cholesterol is essential for maintaining membrane fluidity in eukaryotes. Additionally, the synthetic cascade of cholesterol results in precursor molecules important for cellular function such as lipid raft formation and protein prenylation. As such, cholesterol homeostasis is tightly regulated. Interestingly, it is now known that some cholesterol precursors and many metabolites serve as active signaling molecules, binding to different classes of receptors including the nuclear receptor...

Abstract The liver helps maintain energy homeostasis by synthesizing and storing glucose and lipids. Gonadal steroids, particularly estrogens, play an important role in regulating metabolism. As estrogens are considered female hormones, metabolic disorders related to the disruption of estrogen signaling have mostly been studied in females. Estrogen receptor alpha (ESR1) is the predominant receptor in both the male and female liver, and it mediates the hepatic response to estrogens. Loss of ESR1 ...

Background: Kidney yang deficiency syndrome (KYDS) is one of the most common syndromes treated with traditional Chinese medicine (TCM) among elderly patients. Shen Qi Wan (SQW) has been effectively used in treating various diseases associated with KYDS for hundreds of years. However, due to the complex composition of SQW, the mechanism of action remains unknown. Purpose: To identify the mechanism of the SQW in the treatment of KYDS and determine the molecular targets of SQW. Methods: The potenti...

Qi-Jing-Sheng-Bai granule (QJSB) is a new developed traditional Chinese medicine (TCM) formula. In clinical, it has been used for the treatment of leucopenia. However, the therapeutic mechanism needs further solid investigation. In present study, we first tested the effect of QJSB on leucopenia mice induced by cyclophosphamide with administration of QJSB to leucopenia mice for 8 days. Our experiments showed that QJSB significantly increased the number of peripheral white blood cells, platelets a...

Bile acids are cholesterol-derived surfactants that circulate actively between the liver and ileum and that are classically recognized for emulsifying dietary lipids to facilitate absorption. More recent studies, however, have revealed new functions of bile acids; as pleotropic signaling metabolites that regulate diverse metabolic and inflammatory pathways in multiple cell types and tissues through dynamic interactions with both germline-encoded host receptors and the microbiota. Accordingly, pe...

Lung cancer is a common disease that is associated with poor prognosis. Fungal immunomodulatory protein from Nectria haematococca (FIP-nha) has potential as a lung cancer therapeutic; as such, illuminating its anti-tumor mechanism is expected to facilitate novel treatment options. Here, we showed that FIP-nha affects lung adenocarcinoma growth ex vivo and in vivo. Comparative quantitative proteomics showed that FIP-nha negatively regulates PI3K/Akt signaling and induces cell cycle arrest, autoph...

Background Osteosarcoma is the most common primary bone tumor in children and adolescents. Unfortunately, osteosarcoma treatments often fail due to the development of chemoresistance, of which the underlying molecular mechanisms still remain unclear. In this study, we demonstrated that HSP90AA1 gene is responsible for drug resistance in osteosarcoma through an autophagy-related mechanism.

In this study, the level of gamma-aminobutyric acid (GABA) in wheat bran was increased to be six times higher through the action of endogenous glutamate decarboxylase compared with untreated bran. The process of GABA formation in wheat bran also led to an increased level of phenolic compounds with enhanced antioxidant capacity 2 times higher than the untreated status. The interventional effect of a diet containing GABA-enriched bran on hyperinsulinemia induced by a high-fat diet (HFD) was invest...

Recently, integrative pharmacology(IP) has become a pivotal paradigm for the modernization of traditional Chinese medicines(TCM) and combinatorial drugs discovery, which is an interdisciplinary science for establishing the in vitro and in vivo correlation between absorption, distribution, metabolism, and excretion/pharmacokinetic(ADME/PK) profiles of TCM and the molecular networks of disease by the integration of the knowledge of multi-disciplinary and multi-stages. In the present study, an inte...

Abstract The bile acid-activated receptors, nuclear farnesoid X receptor (FXR) and the membrane Takeda G-protein receptor 5 (TGR5), are known to improve glucose and insulin sensitivity in obese and diabetic mice. However, the metabolic roles of these two receptors and the underlying mechanisms are incompletely understood. Here we studied the effects of the dual FXR and TGR5 agonist INT-767 on hepatic bile acid synthesis and intestinal secretion of glucagon-like peptide-1 (GLP-1) in wild type, Fx...
