Mechanism of total glucosides from Chishao(Radix Paeoniae Rubra)on proliferation and apoptosis of hepatocellular carcinoma cells via phosphatase and tensin homolog deleted on chromosome ten/phosphatidylinositol 3-kinase/protein kinase B signaling pathway

OBJECTIVE:To investigate the possible molecular mechanism of total glycosides of Chishao(Radix Paeoniae Rubra)(TG-RPR)on proliferation and apoptosis of hepatocellular carcinoma cells.METHODS:The proliferation of TG-RPR on Hep G2 cells was detected using the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay.The apoptosis of Hep G2 cells was measured by annexin V-FITC/double staining.The phosphatase and tensin homolog deleted on chromosome ten(PTEN)/phosphatidylinositol 3-kinase(PI3 K)/protein kinase B(Akt)signaling pathway was evaluated by Western Blot and reverse transcription-polymerase chain reaction(RT-PCR).RESULTS:TG-RPR can up-regulation the expression of pro-apoptotic factors such as PTEN and BCL2-Associated X(Bax),down-regulation the expression of anti-apoptotic factors including B-cell lymphoma-2(Bcl-2),PI3 K,and Akt.CONCLUSION:TG-RPR significantly inhibits the proliferation of Hep G2 cells in a dose-dependent manner and promotes apoptosis.These results demonstrated TG-RPR has significant inhibitory effect on Hep G2 cells.These results identify a critical role of TG-RPR in proliferation and apoptosis of Hep G2 cells via modulating PTEN/PI3 K/Akt signaling pathway.TG-RPR may offer a promise as a potential pharmaceutical therapy for hepatocellular carcinoma.

Moutan Cortex and Paeoniae Radix Rubra reverse high-fat-diet-induced metabolic disorder and restore gut microbiota homeostasis

The present study was designed to investigate the therapeutic effcts of Moutan Cortex(CM,root bark of Paeonia suffruticosa Andr) and Paeoniae Radix Rubra(PR,root of Paeonia veitchii Lynch) on metabolic disorders,focusing on the infuence of CM and PR on the obesity-related gut microbiota homeostasis.The diet-induced obese(DIO) mouse model was used to test the therapeutic effects of CM and PR.The mice were orally administered with CM and PR for 6 weeks,and oral glucose tolerance test(OGTT) and insulin tolerance test(ITT) were performed to evaluate the insulin sensitivity of the mice.Sterol-regulatory element binding proteins(SREBPs) and their target genes were measured by quantitative RT-PCR.High-throughput 16 S ribosomal RNA(16S rR NA) gene sequencing technology was used to determine the composition of gut microbiota,and the metabolites in serum were analyzed by GC-MS.Our results indicated that CM and PR combination alleviated obese and insulin resistance in the DIO mice,leading to increased glucose uptake and gene expression in muscle and liver,and down-regulated SREBPs and their target genes in liver.Interesting,neither the CM-PR extracts,nor the major components of CM and PR did not affect SREBPs activity in cultured cells.Meanwhile,CM and PR significantly modulated the gut microbiota of the high-fat diet(HFD) treated mice,similar to metformin,and CM-PR reversed the overall microbiota composition similar to the normal chow diet(NCD) treated mice.In conclusion,our results provide novel mechanisms of action for the effects of CM and PR in treating DIO-induced dysregulation of sugar and lipid metabolism.

Effect of radix paeoniae rubra on expression of p38 MAPK/iNOS/HO-1 in rats with lipopolysaccharide·induced acute lung injury

Objective: To investigate the effect of radix paeoniae rubra (RPR) on expression of p38 mitogen activated protein kinase ( MAPK )/iNOS/HO-1 in rats with lipopolysaccharide-induced acute lung injury and explore the molecular mechanism.Methods: Forty healthy male Wistar rats, weighing 200-250 g, aged 6-8 weeks (mean =7 weeks), provided by the Experimental Center, Medical College, Wuhan University, Wuhan, China, were employed in this study.Under anesthesia with 7% chloraldurat (5 ml/kg body weight) through intraperitoneal injection, the trachea of the rat was exposed and an arterial puncture needle pricked into the trachea via cricothyroid membrane. Then they were randomly divided into five groups: 8 rats receiving 1 ml normal saline through the puncture needle (Group A),8 receiving 1 ml lipopolysaccharide (LPS, 2.5 mg/kg,Group B), 8 receiving LPS and RPR (30 mg/kg, pumped through the femoral vein for 2 hours, Group C ), 8 receiving RPR 2 hours before dripping LPS ( Group D),and 8 receiving hemin (75 μmol/L through intraperitoneal injection) 18 hours before dripping LPS (Group E). After 6 hours of LPS dripping, blood samples were obtained through the carotid artery to perform blood gas analysis,then all the rats were exsanguinated to death and specimens of lung tissues were obtained. The pathomorphological changes of the lung tissues were observed. The expression of p38 MAPK/iNOS/HO-1, the neutrophil ratio, protein content in alveolar irrigating solution and malonaldehyde (MDA) content in the lung tissues were also detected.Results: Compared with Group A, the expression of p38 MAPK, iNOS and HO-1 markedly increased in Groups B, C, D, and E (P ＜0.01). But in Groups C, D, and E,the expression of p38 MAPK and iNOS were significantly lower than that of Group B, while expression of HO-1 was obviously higher than that of Group B ( P ＜ 0.05 ). The protein content, the ratio of neutrophils in bronchoalveolar lavage fluid ( BALF), the content of MDA and the activities of serum NO in Group B were significantly higher than those of Group A ( P ＜ 0.01 ). There was a significant decrease in the level of arterial bicarbonate and partial pressure of oxygen in Group B (P ＜ 0.01). Compared with Group B, these indexes of lung injury were significantly lower while the levels of arterial bicarbonate and partial pressure of oxygen increased significantly in Groups C, D,and E (P ＜ 0.05 or P ＜ 0.01 ). Under light microscope, the pathological changes induced by LPS were significantly attenuated by RPR and hemin.Conclusions: The high expression of MAPK plays an important role in lipopolysaccharide-induced acute lung injury. Protective effect of RPR on lipopolysaccharideinduced acute lung injury may be related to the inhibition of the abnormal high expression of p38 MAPK/iNOS/HO-1.

Protective effects of pretreatment with Radix Paeoniae Rubra on acute lung injury induced by intestinal ischemia/reperfusion in rats

Objective： To investigate the effect of pretreatment with Radix Paeoniae Rubra （RPR） on acute lung injury induced by intestinal ischemia/reperfusion in rats and its protective mechanism. Methods： Thirty-two Wistar rats were randomly divided into four groups： Sham-operation group, ischemla/ reperfusion group （I/R group ）, RPR-pretreatment group and hemin group. The model of intestinal ischemia/ reperfusion was established by clamping the superior mesenteric artery for 1 hour followed by 2-hour reperfusion. The effect of RPR on the expression of heme oxygenase-1 （HO-1） in lung tissues was detected by immunohistochemistry and morphometry computer image analysis. Arterial blood gas analysis, lung permeability index, malondialdehyde （MDA） and superoxide dismutase （SOD） contents in lungs were measured. The histological changes of lung tissue were observed under light microscope. Resalts： The expression of HO-1 in RPR-pretreatment group and hemin group was obviously higher than that in sham-operation group and I/R group （ P 〈 0.01 ）. The level of MDA and lung permeability index in RPR-pretreatment and hemin group were significantly lower than those in I/R group （P〈0.01 or P〈0.05）, while the activity of SOD in RPR-pretreatment and hemin group was obviously higher than that in I/R group （P〈0.01）. Under light microscope, the pathologic changes induced by I/R were significantly attenuated by RPR. Conclusion： Intestinal ischemia/reperfusion may result in acute lung injury and pretreatment with RPR injection can attenuate the injury. The protective effect of RPR on the acute lung injury is related to its property of inducing HO-1 expression and inhibiting lipid peroxidation.

Neuroprotective effect of Paeoniae Radix Rubra on hippocampal CA1 region of mice induced by transient focal cerebral ischemia via anti-gliosis and anti-oxidant activity

Objective: Stroke is the second leading cause of death worldwide. This study aimed to investigate the neuroprotective effect of Paeoniae Radix Rubra(PRR) on ischemic stroke of mice.Methods: The focal ischemic stroke model was produced via middle cerebral artery occlusion. The experimental mice were divided into four groups: vehicle-sham group, PRR-sham group, vehicle-ischemia group, and PRR-treated ischemia group. The cerebral infarction volume was detected with TTC staining.The number of neurons in the hippocampal CA1 of the ischemic side, and the activation of astrocytes and microglia were observed via immunohistochemical staining. Western blotting was used to determine the expression changes of SOD1, SOD2, and Catalase protein levels in the hippocampus.Results: PRR significantly reduced the cerebral infarct volume induced by ischemic injury and inhibited the astrocytes and microglia activation in the hippocampal CA1 region. The decreased levels of SOD1,SOD2, and Catalase that was induced by ischemic reperfusion were simultaneously improved after PRR treatment.Conclusion: PRR improved neuronal injuries that were induced by transient cerebral ischemia via inhibiting gliosis and elevating anti-oxidants.

"Dose-effect-response" Relationships of Paeoniae Radix Rubra on α-Naphthylisothiocyanate-induced Acute Cholestatic Hepatitis in Rats

Objective To investigate the hepatoprotective effects of Paeoniae Radix Rubra(PRR)at different doses against α-naphthylisothiocyanate(α-NIT)-induced acute cholestatic hepatitis in rats.Methods Rats were ig admini-strated with vehicle or PRR[(1,9,18,36,54,72,and 81 g/(kg·d)]3 d before and 2 d afterα-NIT(60 mg/kg)ig administration.The general status of rats,histopathology of liver,serum alanine aminotransaminase,aspartate aminotransaminase,total bilirubin,direct bilirubin,and alkaline phosphatase levels,were observed at respective time points(24 and 48 h)afterα-NIT administration.Using cluster analysis and correspondence analysis,the 'dose-effect-response'relationships of PRR were evaluated.Results The results showed that compared with model group,the serum biochemistry index significantly decreased with the increasing of PRR dosage(P<0.01), and the change and necrosis of hepatic cellula,and inflammatory cell infiltration were gradually alleviated. However,the improvement was not obviously found in the low-dose group[1 g/(kg·d)].The cluster analysis and correspondence analysis results showed that different doses of PRR could significantly ameliorateα-NIT-induced acute cholestatic hepatitis of rats in a dose-dependent manner.Conclusion The experiments show that administration doses of PRR in clinical use should be added properly in order to gain the expectant therapeutic effect,especially in the treatment of heavy acute cholestasis hepatitis.
