ETHNOPHARMACOLOGICAL RELEVANCE:Goiter with hypothyroidism occurs in several thyroid diseases. Xiao-Luo-Wan (XLW), which contains Scrophularia ningpoensis Hemsl., Fritillaria thunbergii Miq. and Ostrea gigas Thunberg, has been used as an effective Chinese medicine for the treatment of goiters in China for hundreds of years. Based on clinical observations and experimental studies, XLW also exerts a certain effect on hypothyroidism. However, the therapeutic mechanism of XLW remains unclear. AIM OF THE STUDY:The present study aimed to investigate the therapeutic effect of XLW on propylthiouracil (PTU)-induced goiter with hypothyroidism in rats and to uncover the underlying molecular mechanism using ultra high-performance liquid chromatography-mass spectrometry (UPLC/MS), network pharmacology, and molecular docking simulations. MATERIALS AND METHODS:After successful modeling, the remaining rats were randomly divided into a model group, an Euthyrox group, an XLW group, and a control group. The corresponding drugs were given by gavage for four consecutive weeks. The growth status was monitored, the relative thyroid weight was calculated, and the total serum T3, T4, and TSH content were detected. Hematoxylin-eosin (H&E) staining was used to observe the pathological changes in the thyroid glands. The chemical components of the XLW were identified by UPLC/MS and the putative targets of XLW were predicted using multiple databases. We performed network pharmacology based on the intersection of goiter/hypothyroidism-related targets and XLW targets. Then, we performed KEGG pathway enrichment analysis, and key targets were further screened using protein-protein interaction (PPI) networks. Finally, molecular docking was used to predict the binding ability of XLW identified components and the key targets. RESULTS:XLW significantly increased the levels of T3 and T4, and reduced TSH, increased body weight, and decreased swollen thyroid glands in PTU-induced rats. XLW promoted the morphological recovery of thyroid follicles and epithelial cells. Twenty-one main chemical components of XLW were identified using UPLC/MS. 270 potential gene targets of XLW and 717 known targets of goiter/hypothyroidism disease were obtained by searching the Traditional Chinese Medicine Systems Pharmacology Database (TCMSP), Swiss Target Prediction, and UniProt databases. A total of 83 KEGG pathways were enriched with phosphatidylinositol 3-kinase-protein kinase B (PI3K-AKT) and RAS signaling pathways. PPI analysis revealed nine key targets of kinase-protein kinase B (AKT) 1, interleukin (IL) 6, vascular endothelial growth factor A (VEGFA), tumor necrosis factor (TNF), glyceraldehyde 3-phosphate dehydrogenase (GAPDH), epidermal growth factor receptor (EGFR), GTPase HRas (HRAS), matrix metalloproteinase (MMP) 9, and heat shock protein 90 alpha family class A member 1 (HSP90AA1). Molecular docking verified which drug components had good binding ability to key targets (all ≤5 kcal/mol). CONCLUSION:For PTU-induced goiter with hypothyroidism in rats, XLW improves thyroid function, reduces goiter, increases body weight, and promotes the recovery of thyroid follicles and epithelial cells. The underlying molecular mechanism suggests that XLW may regulate thyroid hormone signaling by regulating the PI3K-AKT, RAS, and other signaling pathways. This study provides a pharmacological and biological basis for using XLW to treat goiter with hypothyroidism.

Effective substances and molecular mechanisms guided by network pharmacology: An example study of Scrophulariae Radix treatment of hyperthyroidism and thyroid hormone-induced liver and kidney injuries.
Journal of ethnopharmacology
ETHNOPHARMACOLOGICAL RELEVANCE:Scrophulariae Radix (Xuanshen [XS]) has been used for several years to treat hyperthyroidism. However, its effective substances and pharmacological mechanisms in the treatment of hyperthyroidism and thyroid hormone-induced liver and kidney injuries have not yet been elucidated. AIM OF THE STUDY:This study aimed to explore the pharmacological material basis and potential mechanism of XS therapy for hyperthyroidism and thyroid hormone-induced liver and kidney injuries based on network pharmacology prediction and experimental validation. MATERIALS AND METHODS:Based on 31 in vivo XS compounds identified using ultra-performance liquid chromatography tandem quadruple exactive orbitrap high-resolution accurate-mass spectrometry (UPLC-QE-HRMS), a network pharmacology approach was used for mechanism prediction. Systematic networks were constructed to identify the potential molecular targets, biological processes (BP), and signaling pathways. A component-target-pathway network was established. Mice were administered levothyroxine sodium through gavage for 30 d and then treated with different doses of XS extract with or without propylthiouracil (PTU) for 30 d. Blood, liver, and kidney samples were analyzed using an enzyme-linked immunosorbent assay (ELISA) and western blotting. RESULTS:A total of 31 prototypes, 60 Phase I metabolites, and 23 Phase II metabolites were tentatively identified in the plasma of rats following the oral administration of XS extract. Ninety-six potential common targets between the 31 in vivo compounds and the diseases were identified. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed that Bcl-2, BAD, JNK, p38, and ERK1/2 were the top targets. XS extract with or without PTU had the following effects: inhibition of T3/T4/fT3/fT4 caused by levothyroxine; increase of TSH levels in serum; restoration of thyroid structure; improvement of liver and kidney structure and function by elevating the activities of anti-oxidant enzymes catalase (CAT),superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px); activation anti-apoptotic proteins Bcl-2; inhibition the apoptotic protein p-BAD; downregulation inflammation-related proteins p-ERK1/2, p-JNK, and p-p38; and inhibition of the aggregation of pro-inflammatory cytokines TNF-α, IL-1β, and IL-6, as well as immune cells in the liver. CONCLUSION:XS can be used to treat hyperthyroidism and liver and kidney injuries caused by thyroid hormones through its anti-oxidant, anti-inflammatory, and anti-apoptotic properties. In addition, serum pharmacochemical analysis revealed that five active compounds, namely 4-methylcatechol, sugiol, eugenol, acetovanillone, and oleic acid, have diverse metabolic pathways in vivo and exhibit potential as effective therapeutic agents.

Frontiers in pharmacology
The pharmacodynamic substances in "Scrophulariae Radix-Fritillaria" and the molecular mechanisms underlying its therapeutic effects against goiter were analyzed through metabolomics and serum pharmaco-chemistry. A rat model of goiter was established using propylthiouracil (PTU), and the animals were treated using "Scrophulariae Radix-Fritillaria." The efficacy of the drug pair was evaluated in terms of thyroid gland histopathology and blood biochemical indices. Serum and urine samples of the rats were analyzed by UPLC-Q-TOF/MS. Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were performed to screen potential biomarkers in urine and the corresponding metabolic pathways. The blood components of "Scrophulariae Radix-Fritillaria" were also identified, and their correlation with urine biomarkers was analyzed in order to screen for potential bioactive compounds. "Scrophulariae Radix-Fritillaria" mitigated injury to thyroid tissues and normalized the levels of the thyroid hormones FT3, FT4, and TSH. We also identified 22 urine biomarkers related to goiter, of which 19 were regulated by "Scrophulariae Radix-Fritillaria." Moreover, urine biomarkers are involved in tryptophan metabolism, steroid hormone biosynthesis, and beta-alanine metabolism, and these pathways may be targeted by the drug pair. In addition, 47 compounds of "Scrophulariae Radix-Fritillaria" were detected by serum pharmacochemistry, of which nine components, namely, syringic acid, paeonol, cedrol, and cis-ferulic acid, fetisinine, aucubigenin, linolenic acid, ussuriedine, and 5-(methylsulfanyl)pentanenitrile, were identified as potential effective substances against goiter. To summarize, we characterized the chemical components and mechanisms of "Scrophulariae Radix-Fritillaria" involved in the treatment of goiter, and our findings provide an experimental basis for its clinical application.

Using the UHPLC/Q-TOF-MS metabolomics approach, 44 metabolites were found to be profoundly altered in the model group, and the levels of these biomarkers were significantly decreased after treatment with . Forty-four metabolites and 13 signaling pathways related to , including the biosynthesis of unsaturated fatty acids, primary bile acid biosynthesis and sphingolipid metabolism, were explored, and linoleic acid metabolism and sphingolipid metabolism were identified as the most relevant metabolic pathways. In addition, the system pharmacology paradigm revealed that contains 83 active ingredients and is related to 795 genes, and 804 disease genes are related to hyperthyroidism. The construction of the -chemical composition-target-hyperthyroidism network identified a total of 112 intersection genes. The enriched gene targets were analyzed, and five pathways were found to be enriched. Among them pathways, the HIF signaling pathway had the highest enrichment score, which indicated that this pathway might be the main signaling pathway related to the treatment of hyperthyroidism by .The integrated approach involving metabolomics and network pharmacology revealed that might play a role in the treatment of hyperthyroidism by regulating the "IL6-APOA1-cholesterol" pathway and disturbing the HIF signaling pathway. The results demonstrate that the combination of metabolomics and network pharmacology could be used to reflect the effects of on the biological network and metabolic state of hyperthyroidism and to evaluate the drug efficacy of Scrophulariaceae and its related mechanisms.

Radix Scrophulariae Extracts Exert Effect on Hyperthyroidism via MST1/Hippo Signaling Pathway.
Chinese journal of integrative medicine
OBJECTIVE:To explore the mechanism of Radix Scrophulariae (RS) extracts in the treatment of hyperthyroidism rats by regulating proliferation, apoptosis, and autophagy of thyroid cell through the mammalian sterile 20-like kinase 1 (MST1)/Hippo pathway. METHODS:Twenty-four rats were randomly divided into 4 groups according to a random number table: control, model group, RS, and RS+Hippo inhibitor (XMU-MP-1) groups (n=6 per group). Rats were gavaged with levothyroxine sodium tablet suspension (LST, 8 μ g/kg) for 21 days except for the control group. Afterwards, rats in the RS group were gavaged with RS extracts at the dose of 1,350 mg/kg, and rats in the RS+XMU-MP-1 group were gavaged with 1,350 mg/kg RS extracts and 1 mg/kg XMU-MP-1. After 15 days of administration, thyroid gland was taken for gross observation, and histopathological changes were observed by hematoxylin-eosin staining. The structure of Golgi secretory vesicles in thyroid tissues was observed by transmission electron microscopy. The expression of thyrotropin receptor (TSH-R) was observed by immunohistochemistry. Terminal-deoxynucleoitidyl transferase mediated nick end labeling assay was used to detect cell apoptosis in thyroid tissues. Real-time quantity primer chain reaction and Western blot were used to detect the expressions of MST1, p-large tumor suppressor gene 1 (LATS1), p-Yes1 associated transcriptional regulator (YAP), proliferating cell nuclear antigen (PCNA), G/S-specific cyclin-D1 (Cyclin D1), B-cell lymphoma-2 (Bcl-2), Caspase-3, microtubule-associated proeins light chain 3 II/I (LC3-II/I), and recombinant human autophagy related 5 (ATG5). Thyroxine (T4) level was detected by enzyme-linked immunosorbent assay. RESULTS:The thyroid volume of rats in the model group was significantly increased compared to the normal control group (P<0.01), and pathological changes such as uneven size of follicular epithelial cells, disorderly arrangement, and irregular morphology occurred. The secretion of small vesicles by Golgi apparatus was reduced, and the expressions of receptor protein TSH-R and T4 were significantly increased (P<0.01), while the expressions of MST1, p-LATS1, p-YAP, Caspase-3, LC3-II/I, and ATG5 were significantly decreased (P<0.01). The expressions of Bcl-2, PCNA, and cyclin D1 were significantly increased (P<0.01). Compared with the model group, RS extracts reduced the volume of thyroid gland, improved pathological condition of the thyroid gland, promoted secretion of the secretory vesicles with double-layer membrane structure in thyroid Golgi, significantly inhibited the expression of TSH-R and T4 levels (P<0.01), upregulated MST1, p-LATS1, p-YAP, Caspase-3, LC3-II/I, and ATG5 expressions (P<0.01), and downregulated Bcl-2, PCNA, and Cyclin D1 expressions (P<0.01). XMU-MP-1 inhibited the intervention effects of RS extracts (P<0.01). CONCLUSION:RS extracts could inhibit proliferation and promote apoptosis and autophagy in thyroid tissues through MST1/Hippo pathway for treating hyperthyroidism.

Transcriptomic and proteomic investigations identify PI3K-akt pathway targets for hyperthyroidism management in rats via polar iridoids from .
Heliyon
High-polarity iridoids from () offer a range of benefits, including anti-inflammatory, antioxidant, antitumour, antibacterial, antiviral, and antiallergic effects. Although previous studies have indicated the potential of for hyperthyroidism prevention and treatment, the specific active compounds involved and their mechanisms of action are not fully understood. This study explored the effects of high-polarity iridoid glycosides from on hyperthyroidism induced in rats by levothyroxine sodium. The experimental design included a control group, a hyperthyroidism model group, and a group treated with iridoid glycosides. Serum triiodothyronine (T3) and thyroxine (T4) levels were quantified using an enzyme-linked immunosorbent assay (ELISA). Transcriptomic and proteomic analyses were applied to liver samples to identify differentially expressed genes and proteins. These analyses were complemented by trend analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The effectiveness of key factors was further examined through molecular biology techniques. ELISA results indicated a notable increase in T3 and T4 in the hyperthyroid rats, which was significantly mitigated by treatment with iridoid glycosides. Transcriptomic analysis revealed 6 upregulated and 6 downregulated genes in the model group, showing marked improvement following treatment. Proteomic analysis revealed changes in 30 upregulated and 50 downregulated proteins, with improvements observed upon treatment. The PI3K-Akt signalling pathway was investigated through KEGG enrichment analysis. Molecular biology methods verified the upregulation of Spp1, Thbs1, PI3K, and Akt in the model group, which was reversed in the treatment group. This study revealed that highly polar iridoids from can modulate the Spp1 gene and Thbs1 protein via the PI3K-Akt signalling pathway, suggesting a therapeutic benefit for hyperthyroidism and providing a basis for drug development targeting this condition.
