Organic anion transporting polypeptide 1B1 (OATP1B1) is an important liver-specific uptake transporter, which mediates transport of numerous endogenous substances and drugs from blood into hepatocytes. To identify and investigate potential modulators of OATP1B1 from natural products, the effect of 21 frequently used natural compounds and extracts on OATP1B1-mediated fluorescein methotrexate transport was studied by using Chinese hamster ovary cells stably expressing OATP1B1 (CHO-OATP1B1) in 96-well plates. This method could be used for the screening of large compound libraries. Our studies showed that some flavonoids (e.g., quercetin, quercitrin, rutin, chrysanthemum flavonoids and mulberrin) and triterpenoids (e.g., glycyrrhetinic acid and glycyrrhizic acid) were inhibitors of OATP1B1 with IC50 values less than 16 µmol · L(-1). The IC50 value of glycyrrhetinic acid on OATP1B1 was comparable to its blood concentration in clinics, indicating an OATPlB1-mediated drug-drug interaction could occur. Structure-activity relationship analysis showed that flavonoids had much higher inhibitory activity than their glycosides. Furthermore, the type and length of saccharides had a significant effect on their activity. In addition, we used OATP1B1 substrates fluvastatin and rosuvastatin as probe drugs to investigate the substrate-dependent effect of several natural compounds on the function of OATP1B1 in vitro. Our results demonstrated that the effect of these natural products on the function of OATPlB1 was substrate-dependent. In summary, this study would be conducive to predicting and avoiding potential OATP1B1-mediated drug-drug and drug-food interactions and thus provide the experimental basis and guidance for rational drug use.

Objective: To explore the in vitro inhibition effect of Zuojin pills on 6 cytochrome P450 isoenzymes ( CYP1A2, CYP2C8, CYP2C9, CYP2C19, CYP2D6 and CYP3A4) in human liver microsomes. Methods:The water extract of Zuojin pills, Cop-tidis Rhizoma and Euodiae Fructus was respectively incubated with human liver microsomes in the presence of seven probe substrates of CYP450 isoenzymes, and seven metabolites of cytochrome P450 probe substrate ( paracetamol/CYP1A2, 6α-hydroxypaclitaxel/CYP2C8, 4-hydroxydiclofenac/CYP2C9, 4-hydroxymephenytoin/CYP2C19, dextrorphan/CYP2D6, 6β-hydroxytestosterone/CYP3A4 and 1-hydroxymidazolam/CYP3A4) were simultaneously measured by LC-MS/MS, and the inhibitory effects were evaluated with IC50 value. Results:The IC50 value of Zuojin pills on CYP2D6, CYP1A2 and CYP3A4_T was 11. 6, 77. 4 and 97. 0 μg·ml-1 , respec-tively. The other IC50 values were from 334 to 690μg·ml-1 on CYP2C8, CYP2C9, CYP2C19 and CYP3A4_M isoenzymes. The IC50 value of Coptidis Rhizoma on CYP2D6, CYP1A2 and CYP3A4_T was 5. 8, 36. 8 and 59. 2 μg·ml-1 , respectively. The other IC50 values were from 163 to 476 μg·ml-1 on CYP2C8, CYP2C9, CYP2C19 and CYP3A4_M isoenzymes. The IC50 value of Euodiae Fructus on CYPs was over 107 μg·ml-1 . Conclusion:Zuojin pills shows notable inhibitory effect on CYP2D6, and weak inhibitory effects on CYP1A2 and CYP3A4_T. Coptidis Rhizoma has similar effects on CYPs and may be the main herbal medicine in the formu-la. Therefore, much attention should be paid to the combination of Zuojin pills and the drugs metabolized by human CYP2D6 in clin-ics.

Objective:To identify the pathogenic gene mutations in a family with early onset severe retinal dystrophy (EOSRD).Methods:A retrospective clinical study. One patient and three family members from a Han of EOSRD who were diagnosed at Henan Eye Hospital in August 2018 were included in the study. After the detailed history of the patients was collected, all participants underwent best corrected visual acuity (BCVA), slit-lamp, fundus biomicroscopy with the slit lamp, untra-widefield fundus color photography, spectral-domain optical coherence tomography (SD-OCT) and full-field electroretinography (ff-ERG). The subject’s peripheral venous blood of 5 ml was collected and the whole genome DNA was extracted. A genetic eye disease capture chip containing 441 disease-causing genes was used for targeted capture and enrichment of high-throughput sequencing, and Sanger sequencing was performed for the clear pathogenic mutation sites; the analysis software was used for bioinformatics analysis of the mutation sites.Results:A 6-year-old female proband developed poor night vision in both eyes after 1 year old. The BCVA of both eyes were 0.1. The color of the optic disc was slightly lighter; the diameter of the retinal vessels was slightly reduced, and extensive pigment changes can be seen in the retina outside the vascular arch. SD-OCT examination showed that the outer membrane, ellipsoid zone and chimera zone in the central fovea of both eyes were unclear and intermittent. The visual area outside the fovea was neuroepithelial outer plexiform layer, outer nuclear layer, outer membrane, ellipsoid zone. The chimera zone gradually disappeared, and the thickness of the pigment epithelial layer was not uniform. In ff-ERG examination, the functions of the binocular cone and rod system were severely decreased. The results of genetic testing showed that there were c.921C>A homozygous mutations in the Tubby-like protein (TULP1) gene of the proband, and c.3121C>T and c.3488G>A compound heterozygous mutations in the cyclic nucleotide gated channel beta 1 (CNGB1) gene. Amino acid conservation analysis results showed that the above three mutation sites were highly conserved in multiple species; bioinformatics analysis results showed that TULP1 gene c.921C>A (p.Cys307*) had translation termination in the protein conserved region, CNGB1 gene c.3121C>T (p.Arg1041Trp) and c.3488G>A (p.Gly1163Glu) had amino acid polarity changes in the protein conserved region, which led to major changes in the protein spatial structure.Conclusion:TULP1 gene c.921C>A homozygous mutation, CNGB1 gene c.3121C>T and c.3488G>A compound heterozygous mutation are the mutation sites of this EOSRD family.

Objective To analyze the main active components and potential molecular mechanism of Sophora flavescens against breast cancer based on network pharmacology and molecular docking. Methods The chemical constituents were collected and screened by TCMSP, ETCM database and literature review. The targets of active ingredients were predicted by Swiss Target Prediction database. Breast cancer-related targets were collected by GeneCards, TTD, Drugbank and OMIM. The anti-breast cancer targets of Sophora flavescens were screened by Venny 2.1.0 software. Cytoscape software was used to construct the network diagram of Sophora flavescens-key active ingredients-targets. STRING database was used to analyze the common targets, and PPI network diagram was constructed. GO function enrichment analysis and KEGG pathway enrichment analysis of key target proteins were performed by DAVID database and Hiplot online platform. Schrodinger software was used to calculate the molecular docking between the active ingredients and targets. Molecular biological methods were used to verify the key targets. Results A total of 36 active components with clear structures were screened from Sophora flavescens. 70 anti-breast cancer targets of Sophora flavescens were screened out. 12 core targets including EGFR, AKT1, ESR1, SRC, CYP19A1, AR and ABCB1 participate in endocrine resistance, EGFR tyrosine kinase inhibitors and estrogen signaling pathways in breast cancer. Moreover, the docking score between the core component and the key target AR is the highest. In vitro experiments showed that the extract of Sophora flavescens can inhibit the proliferation of breast cancer cells, induce cell apoptosis and up-regulate AR protein expression. Conclusion It was revealed that Sophora flavescens plays an anti-breast cancer role by regulating complex biological processes through multiple components acting on multiple targets and signaling pathways. The upregulation of AR protein by Sophora flavescens may become a new therapeutic strategy for the treatment of breast cancer.

Paclitaxel is the first-line chemotherapy drug for a variety of cancers. However, the paclitaxel resistance greatly reduced the efficacy in the later treatment stage, which seriously increased the mortality and recurrence rate of cancer and limited the clinical application of paclitaxel. At present, Chinese medicine compound prescription, proprietary Chinese medicine, and Chinese medicine injection are widely used as the adjuvant chemotherapy drugs for the treatment of cancer in clinic. Chinese medicine has shown unique advantages in improving the efficacy of chemotherapy drugs and the prognosis of chemotherapy, and reducing the toxic and side effects. However, the specific mechanism and effective monomer composition of Chinese medicine for reversing the resistance of chemotherapy drugs are unclear, and the application of Chinese medicine in different types of cancer is also limited, which are worthy of further exploration. This review summarized the composition of Chinese medicine monomer with synergistic antitumor effect combined with paclitaxel in recent years. The specific mechanism and pharmacological activities of Chinese medicine monomer reversing paclitaxel resistance were classified. This review found that through acting on the membrane transport protein, Chinese medicine monomer promoted the accumulation of paclitaxel in tumor cells, inhibited the expressions of protein and metabolic enzyme related to multidrug resistance and the metabolism of paclitaxel, and regulated the levels of apoptosis genes and factors and apoptosis-related pathways to promote the inhibitory effect of paclitaxel on cell proliferation. Chinese medicine monomer also significantly improved paclitaxel chemotherapy sensitivity by regulating the expression levels of micro ribonucleic acid (microRNA) and long non-coding ribonucleic acid RNA (lncRNA), inhibiting the characteristics of tumor stem cells and tumor metabolic reprogramming, improving tumor microenvironment, and triggering tumor cell death autophagy and oxidative stress response. This review provides a theoretical basis for clarifying the specific anti-tumor mechanism of Chinese medicine monomer combined with paclitaxel, which is of great significance for the development of new Chinese medicine and the clinical research of the drugs combined with paclitaxel, and has certain value for the application of Chinese medicine combined with other chemotherapy drugs.
