Development and validation of an RBP gene signature for prognosis prediction in colorectal cancer based on WGCNA.

BACKGROUND: RNA binding proteins (RBPs) have been implicated in oncogenesis and progression in various cancers. However, the potential value of RBPs as prognostic indicators and therapeutic targets in colorectal cancer (CRC) requires further investigation. METHODS: Four thousand eighty two RBPs were collected from literature. The weighted gene co-expression network analysis (WGCNA) was performed to identify prognosis-related RBP gene modules based on the data attained from the TCGA cohorts. LASSO algorithm was conducted to establish a prognostic risk model, and the validity of the proposed model was confirmed by an independent GEO dataset. Functional enrichment analysis was performed to reveal the potential biological functions and pathways of the signature and to estimate tumor immune infiltration. Potential therapeutic compounds were inferred utilizing CMap database. Expressions of hub genes were further verified through the Human Protein Atlas (HPA) database and RT-qPCR. RESULTS: One thousand seven hundred thirty four RBPs were differently expressed in CRC samples and 4 gene modules remarkably linked to the prognosis were identified, based on which a 12-gene signature was established for prognosis prediction. Multivariate Cox analysis suggested this signature was an independent predicting factor of overall survival (P < 0.001; HR:3.682; CI:2.377-5.705) and ROC curves indicated it has an effective predictive performance (1-year AUC: 0.653; 3-year AUC:0.673; 5-year AUC: 0.777). GSEA indicated that high risk score was correlated with several cancer-related pathways, including cytokine-cytokine receptor cross talk, ECM receptor cross talk, HEDGEHOG signaling cascade and JAK/STAT signaling cascade. ssGSEA analysis exhibited a significant correlation between immune status and the risk signature. Noscapine and clofazimine were screened as potential drugs for CRC patients with high-risk scores. TDRD5 and GPC1 were identified as hub genes and their expression were validated in 15 pairs of surgically resected CRC tissues. CONCLUSION: Our research provides a depth insight of RBPs' role in CRC and the proposed signature are helpful to the personalized treatment and prognostic judgement.

Cellular pharmacokinetics and pharmacodynamics mechanisms of ginkgo diterpene lactone and its modulation of P-glycoprotein expression in human SH-SY5Y cells.

Ginkgo diterpene lactone (GDL) is the raw material for ginkgo diterpene lactone meglumine injection, which is used for treating cerebral ischemia. The aims of this study were to explore the cellular pharmacokinetics of GDL in whole cells and subcellular fractions, and detect cellular pharmacodynamics on the human SH-SY5Y cells induced by oxygen-glucose deprivation and reoxygenation (OGD/R). Firstly, a simple, sensitive and reliable liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for assessing the amount of ginkgolide A (GA), B (GB) and K (GK) in cellular/subcellular samples. Then, phosphatidylserine and mitochondria membrane potential were assayed to evaluate the extent of apoptosis effect. The study showed that the cellular/subcellular accumulation of GA and GB were increased in a concentration-dependent manner; the levels of GA and GB in cytosol were the highest among these subcellular organelles. Meanwhile, GDL also attenuated the OGD/R-induced increases in the percentage of apoptotic and mitochondria membrane potential. In addition, verapamil increased the rate and amount of GA and GB entering cellular/subcellular compartments through inhibition of P-glycoprotein activity, and promoted the protective effect of GDL. The present study reports the cellular pharmacokinetics profiles of GA and GB in normal and OGD/R-induced SH-SY5Y cells in vitro for the first time, which provided valuable information for clinical safety application.

Akebia Saponin D Regulates the Metabolome and Intestinal Microbiota in High Fat Diet-Induced Hyperlipidemic Rats.

Hyperlipidemia is a major component of metabolic syndrome, and regarded as one of the main risk factors causing metabolic diseases. We have developed a therapeutic drug, akebia saponin D (ASD), and determined its anti-hyperlipidemia activity and the potential mechanism(s) of action by analyzing the metabolome and intestinal microbiota. Male Sprague-Dawley rats were fed a high fat diet to induce hyperlipidemia, and then given ASD orally for 8 weeks. Lipid levels in serum were determined biochemically. Metabolites in serum, urine and feces were analyzed by UPLC-Q/TOF-MS, and the structure of the intestinal microbiota was determined by 16S rRNA sequencing. The ASD treatment significantly decreased the levels of TC, TG and LDL-c and increased the serum level of HDL-c. Metabolomics analysis indicated that the ASD treatment mainly impacted seven differential metabolites in the serum, sixteen differential metabolites in the urine and four differential metabolites in feces compared to the model group. The ASD treatment significantly changed eight bacteria at the genus level compared to the model group. In conclusion, ASD treatment can significantly alleviate HFD-induced hyperlipidemia and the hypolipidemic effect of ASD treatment is certainly associated with a systematic change in the metabolism, as well as dynamic changes in the structure of the intestinal microbiota.

[Protective effect of Longxue Tongluo capsule on oxidized low-density lipoprotein damage to human umbilical vein endothelial cells].

To observe the protective effect of Longxue Tongluo capsule (LTC) on human umbilical vein endothelial cells (EAhy.926 cells) injury induced by oxidized low-density lipoprotein (ox-LDL, 100 mg·L⁻¹). The effect of the cell viability of LTCin alleviating OX-LDL-induced endothelial cell injury was determined by MTT and LDH assay. The effect of LTC on lactic dehydrogenase (LDH), nitric oxide (NO), super oxide dlsmutase (SOD) and malondialdehyde (MDA) levels were detected by corresponding assay kits according to manufacturer's instruction. The effect of LTC on the protein expressions of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), p65, p-p65, IKB and p-IKB were detected by Western blot. The results showed that compared with the normal control group, the activity of EAhy.926 cells was significantly decreased, LDH leakage (P<0.01) increased, NO content and SOD activity significantly decreased (P<0.01, P<0.05), and the expressions of ICAM-1, VCAM-1, p-p65/p65 and p-IKB(P<0.05)increased.This study demonstrated that LTC had no significant effect on the growth of normal cells. The treatment with LTC significantly promoted the proliferation of vascular endothelial cells damagedby ox-LDL, decreased MDA content and LDH release, andincreased the activity of SOD and NO content. Meanwhile, ox-LDL significantly increased the expressions of ICAM-1, VCAM-1, p-p65/p65, p-IKB/IKB in Eahy.926 cells; these effects were suppressed by LTC at 1, 2 mg·L⁻¹. In conclusion, LTC has a significant protective effect on human umbilical vein endothelial cells caused by ox-LDL. This study suggested that LTC has a certain therapeutic effect on AS.

[Effect of Longxuetongluo capsule in protecting vascular endothelial cells against oxygen-glucose deprivation/reoxygenation-induced apoptosis].

Focal cerebral ischemia reperfusion is an essential process during ischemic stroke. The apoptosis of vascular endothelial cells induced by ischemia/reperfusion (I/R) injury is an important cause for brain injury after focal cerebral ischemia. Longxuetongluo capsule (LTC) has been used for the treatment of ischemic stroke in clinic. However, its underlying action mechanism is still unclear. This study aimed to verify the protective effect and mechanisms of LTC on HUVEC cells against oxygen-glucose deprivation/reoxygenation (OGD/R) injury through MTT, LDH, flow cytometry, AO/EB staining and western blot assays. As a result, OGD/R significantly decreased the viability of HUVEC cells, which was significantly improved by LTC. LDH release assay showed that OGD/R significantly increased the lactate dehydrogenase (LDH) release, and LTC dramatically reduced the OGD/R-induced LDH release. Further mechanism study indicated that LTC dose-dependently inhibited the cleavage of PARP, caspase 3, and caspase 9 induced by OGD/R, suggesting that LTC could inhibit the activation of caspase 3/9 apoptosis pathway in the OGD/R-induced apoptosis of HUVEC cells. In conclusion, LTC could protect HUVEC cells against OGD/R injury by inhibiting the activation of mitochondria-related caspase 3/9 apoptosis pathway.

Discovery of acylguanidine oseltamivir carboxylate derivatives as potent neuraminidase inhibitors.

In search of novel anti-influenza agents with higher potency, a series of acylguanidine oseltamivir carboxylate analogues were synthesized and evaluated against influenza viruses (H1N1 and H3N2) in vitro. The representative compounds with strong inhibitory activities (IC50 <40nM) against neuraminidase (NA) were further tested against the NA from oseltamivir-resistant strain (H259Y). Among them, compounds 9 and 17 were potent NA inhibitors that exhibited a 5 and 11-fold increase in activity comparing with oseltamivir carboxylate (2, OC) against the H259Y mutant, respectively. Furthermore, the effect against influenza virus H259Y mutant (H1N1) replication and cytotoxicity assays indicated that compounds 9 and 17 exhibited a 20 and 6-fold increase than the parent compound 2, and had no obvious cytotoxicity in vitro. Moreover, the molecular docking studies revealed that the docking modes of compounds 9 and 17 were different from that of oseltamivir, and the new hydrogen bonds and hydrophobic interaction were formed in this case. This work provided unique insights in the discovery of potent inhibitors against NAs from wild-type and oseltamivir-resistant strains.

Simultaneous determination of 35 ultra-trace level organophosphorus pesticide residues in Sanjie Zhentong capsules of traditional Chinese medicine using ultra high performance liquid chromatography with tandem mass spectrometry.

The aim of this study was to develop an analytical method for the simultaneous determination of ultra-trace levels of 35 organophosphorus pesticide residues in Sanjie Zhentong capsules, a traditional Chinese medicine prescription. A method based on multiclass and multiresidue sample preparation was developed. First, samples were hydrated with water at 4°C. A ratio of 1:3 sample/water was used for each of the sample amounts. Then, different extraction solvents were screened. This step was followed by a dispersive solid-phase extraction clean-up procedure using both primary secondary amine and polyamide. A comprehensive sensitive multiresidue liquid chromatography tandem mass spectrometry method was investigated and validated. Good linearity was achieved in the range of 10-500 µg/kg for each analyte. The average recovery ranged from 70 to 120%, except for methamidophos, fonophos, diazinon, and chlorpyriphos-ethyl, the recoveries of which ranged from 60-70% at the lower concentration level. The precision values were lower than 10% for all the compounds in three concentration levels. The limits of detection and limits of quantification values were 0.01-2.1 and 0.05-3.4 µg/kg, respectively. The matrix effects were determined, and most of the compounds showed signal suppression. Finally, this optimized procedure was applied for the analysis of real samples.

Direct inhibition of Re Du Ning Injection and its active compounds on human liver cytochrome P450 enzymes by a cocktail method.

The aim of this study was to investigate the direct inhibitory effects of Re Du Ning Injection (RDN) and its active compounds on the major cytochrome P450 enzyme (CYP) isoforms (CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6 and CYP3A4) of human liver microsomes by 'a cocktail method'. The activity of each CYP isform was represented as the formation rate of the specific metabolite from relevant substrate. Then a sensitive and specific ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed and validated to simultaneously analyze the seven metabolites. RDN (0.035-2.26 mg/mL) showed a strong inhibitiory effect on CYP2C8, followed by CYP2C9, CYP2B6, CYP2C19, CYP1A2 and CYP3A4. The IC50 value for each enzyme was 0.19, 0.66, 0.72, 1.27, 1.66 and 2.13 mg/mL, respectively. RDN competitively inhibited the activities of CYP1A2 (Ki = 1.22 mg/mL), CYP2B6 (Ki = 0.65 mg/mL) and CYP3A4 (Ki = 0.88 mg/mL); it also exhibited mixed inhibition of CYP2C8, CYP2C9 and CYP2C19 with a Ki value of 0.26, 0.64 and 0.82 mg/mL, respectively. However, the activity of CYP2D6 was not significantly inhibited even by 2.26 mg/mL RDN. Moreover, the data of nine active compounds on the CYPs showed that cryptochlorogenin acid, sochlorogenic acid B and sochlorogenic acid C were the major contributors to the inhibitory effect of RDN on CYP2C8, while the inhibitory effect of RDN on CYP2C9 might be caused by sochlorogenic acid A and sochlorogenic acid C. Moreover, neochlorogenic acid might be the major contributor to the inhibitory effect on CYP2B6. All of the findings suggested that drug-drug interactions may occur and great caution should be taken when RDN is combined with drugs metabolized by these CYPs.
