Objective::To observe the intervention effect of Yiqi Huoxue recipe (YQHX) on ventricular remodeling in rats with chronic heart failure, in order to explore its mechanism. Method::Among 40 male SD rats, 10 were randomly selected as the sham operation group. The left anterior descending coronary artery ligation was performed to construct the chronic heart failure(CHF) rat model. After modeling, they were randomly divided into model group, captopril group(13.5 mg·kg-1·d-1) and YQHX group (20 g·kg-1·d-1), and orally given the corresponding drugs. After 8 weeks of intervention, cardiac tissues were collected, body mass and heart mass were weighed, and echocardiography were performed to detect the changes in cardiac structure. Masson staining was performed to determine the myocardial interstitial collagen volume fraction. Western blot was used to detect the expression levels of mitochondrial fusion protein optic atrophy 1 (Opa1) and cleavage protein dynamic-related protein 1 (Drpl). The quantitative real-time fluorescence polymerase chain reaction(Real-time PCR)was applied to detect the expressions of Wnt/β-catenin pathway-related factors such as lipoprotein receptor-related protein 6 (LRP6), glycogen synthase kinase-3β (GSK-3β) and β-catenin. Result::Compared with the sham group, the left ventricular wall of the model group was significantly thickened (P<0.05), the cardiac cavity was significantly enlarged, and the content of collagen in the myocardial interstitium was increased (P<0.01). The expression level of Opal decreased, the expression level of Drp1 increased (P<0.05), the mRNA expression level of LRP6, GSK-3, and β-catenin increased (P<0.01). Compared with the model group, YQHX group can reduce ventricular wall thickening, heart chamber enlargement, myocardial interstitial collagen content, up-regulate the low expression of Opa1, but down-regulate the high expressions of Drpl, LRP6, GSK-3β, β-catenin(P<0.05, P<0.01). Conclusion::YQHX can effectively alleviate ventricular remodeling and improve mitochondrial energy metabolism in rats with CHF. The mechanism may be related to the inhibition of Wnt/β-catenin related factors.

WM130 preferentially inhibits hepatic cancer stem-like cells by suppressing AKT/GSK3β/β-catenin signaling pathway / 中国药理学与毒理学杂志

OBJECTIVE The eradication of cancer stem cells(CSCs)is signifcant for cancer therapy and prevention.METHODS In this study,we evaluated WM130,a novel derivative of matrine,for its effect on CSCs using human hepatocellular carcinoma(HCC)cell lines,their sphere cells,and sorted EpCAM+cells. RESULTS We revealed that WM130 could not only inhibit proliferation and colony formation of HCC cells, but also suppress the expression of some stemness-related genes and up-regulate some mature hepatocyte marker genes, indicating a promotion of differentiation from CSCs to hepatocytes. WM130 also suppressed the proliferation of doxorubicin-resistant hepatoma cells, and markedly reduced the cells with CSC biomarker EpCAM.Moreover,WM130 suppressed HCC spheres,not only primary spheres but also subsequent spheres,indicating an inhibitory effect on self-renewal capability of CSCs.Interestingly,WM130 exhibiteda remarkable inhibitory preference on HCC spheres and EpCAM+cells rather than their parental HCC cells and EpCAM- cells respectively. In vivo, WM130 inhibited HCC xenograft growth, decreased the number of sphere-forming cells, and remarkably decreased the levels of EpCAM mRNA and protein in tumor xenografts. Better inhibitory effect was achieved by WM130 in combination with doxorubicin.Further mechanism study revealed that WM130 inhibited AKT/GSK3β/β-catenin signaling pathway. CONCLUSION Collectively, our results suggest that WM130 remark-ably inhibits hepatic CSCs, and this effect may via the down-regulation of the AKT/GSK3β/β-catenin pathway.These findings provide a strong rationale for the use of WM130 as a novel drug candidate in HCC therapy.

Research progress of the exosomes as drug delivery vehicles of Chinese herbal drugs / 药学学报

As a new carrier of intercellular information, the exosomes is widely regarded as a natural drug carrier for its extensive distribution, non-immunity and targeting in human body.

Interaction of E3 ligase HUWE1 and eukaryotic translation initiation factor eIF4E / 药学学报

To explore the regulation of eIF4E, we screened the protein interacting with eIF4E from human cDNA library by using yeast two-hybrid system. Several clones interacting with eIF4E were identified. One of them was homologous with HUWE1 (HECT, UBA and WWE domain containing 1, also named as ARF-BP1, HECTH9 or HUWE1). Cell co-immunoprecipitation showed that eIF4E could bind to HUWE1 in mammalian cells. We also found that HUWE1 bearing the HECT domain is necessary for its association with eIF4E.

Endoplasmic reticulum stress and vascular endothelial cell apoptosis / 中国医学科学院学报

Endoplasmic reticulum stress (ERS) is a new pathway of apoptosis following the discovery of death receptor signaling pathway and mitochondrial pathway. By activating the unfolded protein response (UPR), ERS can suspend protein synthesis, restore the endoplasmic reticulum homeostasis, and thus play a protective role for cells; however, if the inducing factors of ERS persist, ERS will continue to trigger C/EBP homologous protein, JNK, caspase, or other pathways to induce apoptosis. In addition, the injury and apoptosis of vascular endothelial cells are key links in various diseases and pathophysiologic processes, and research has also shown that vascular endothelial cell apoptosis is closely related with the ERS. Effective intervention of ERS may restrain apoptosis and protect the vascular endothelium. This article reviews the recent research advances in ERS and its role in vascular endothelial cell apoptosis.
