Bufalin Induces Programmed Necroptosis in Triple-Negative Breast Cancer Drug-Resistant Cell Lines through RIP1/ROS-Mediated Pathway

引用

Chinese Journal of Integrative Medicine 2022年第10期28卷 900-908页

作者： LIU Xiao-dan SONG Cheng-yang KONG cui-cui TIAN xin Department of Breast Surgery the Fourth Affiliated Hospital of China Medical UniversityShenyang(110032)China Department of Thoracic Surgery the Fourth Affiliated Hospital of China Medical UniversityShenyang(110032)China Molecular Oncology Laboratory of Cancer Research Institute the First Affiliated Hospital of China Medical UniversityShenyang(110001)China

Objective: To explore the effect and mechanism of action of bufalin in triple-negative breast cancer(TNBC) drug-resistant cell lines. Methods: The normal human mammary epithelial cell line, TNBC cell line, TNBC adriamycin-resistant cell line, and TNBC docetaxel-resistant cell line were treated with different doses of bufalin(0–1,000 nmol/L) at different time points(0–72 h). Propidium iodide staining, AV-FITC/PI double staining, Hoechst 33342/PI double staining and transmission electron microscopy(TEM) were used to evaluate the death patterns of the cell lines. Results: Bufalin killed the TNBC cell line and its drug-resistant cell lines in a dose/time-dependent manner(all P<0.01). After treatment with bufalin for 24 h, the adriamycinresistant cell line showed a co-existing pattern of necroptosis and apoptosis. However, at 48 h, necroptosis was the main manifestation. After treatment with bufalin, the expressions of tumor necrosis factor α, phospho-tumor necrosis factor receptor 1, phospho-receptor interacting protein 1 and c-caspase 3 increased(all P<0.01), the killing effect of bufalin could be mostly inhibited by NEC-1, and by z-VAD-fmk(both P <0.01). Besides, the intracellular reactive oxygen species(ROS) levels increased considerably(P<0.01), the antioxidant N-acetyl cysteine or Nec-1 could inhibit the increase of ROS level and the killing effect of bufalin(all P<0.01). The adriamycin-resistant cell line exhibited necroptosis characteristic after 48 h of bufalin treatment under TEM. Conclusions: Bufalin could induce necroptosis through RIP1/ROS-mediated pathway to kill the drug-resistant TNBC cell lines. This finding provides critical experimental data and theoretical basis for the clinical application of bufalin to overcome the difficulties in the treatment of TNBC.

Development of sintered Ni-Cu wicks for loop heat pipes

Science China(Technological Sciences) 2009年第6期52卷 1607-1612页

作者： xin GongMing cui KeHang ZOU Yong CHENG Lin Institute of Thermal Science and Technology Shandong UniversityJinan 250061China

The present study fabricated a series of capillary wicks for loop heat pipes (LHPs), using two different methods, the cold-pressing sintering and direct loose sintering, and experimentally investigated the effect of different methods, compositions and sintering parameters on their properties in terms of porosity, permeability and pore radius. Porosity and pore radius were measured by the Archimedes method and Scanning Electron Microscope (SEM), respectively. Permeability of the wicks was compared by calculation using empirical equation. Results show that capillary wicks were successfully fabricated by using two different methods; the optimal capillary wick was found to be sintered at 650°C for 30 min, using direct loose sintering technique, with 90% nickel and 10% copper. The wicks could reach the porosity of 70.07% and the permeability of 10?13 m2 order, with mean pore radius of 0.54 μm.

Solar flare forecasting using learning vector quantity and unsupervised clustering techniques

引用

Science China(Physics,Mechanics & Astronomy) 2011年第8期54卷 1546-1552页

作者： LI Rong WANG HuaNing cui YanMei HUANG xin School of Information Beijing WuZi University Beijing 101149 China The National Astronomical Observatories Chinese Academy of Sciences Beijing 100012 China Center for Space Science and Applied Research Chinese Academy of Sciences Beijing 100190 China

In this paper, a combined method of unsupervised clustering and learning vector quantity (LVQ) is presented to forecast the occurrence of solar flare. Three magnetic parameters including the maximum horizontal gradient, the length of the neutral line, and the number of singular points are extracted from SOHO/MDI longitudinal magnetograms as measures. Based on these pa- rameters, the sliding-window method is used to form the sequential data by adding three days evolutionary information. Con- sidering the imbalanced problem in dataset, the K-means clustering, as an unsupervised clustering algorithm, is used to convert imbalanced data to balanced ones. Finally, the learning vector quantity is employed to predict the flares level within 48 hours. Experimental results indicate that the performance of the proposed flare forecasting model with sequential data is improved.

Delayed onset and fast rise of prompt optical-UV emission from gamma-ray bursts in molecular clouds

引用

Research in Astronomy and Astrophysics 2013年第1期13卷 57-70页

作者： Xiao-Hong cui Zhuo Li Li-Ping xin National Astronomical Observatories Chinese Academy of Sciences Department of Astronomy Peking University Kavli Institute for Astronomy and Astrophysics Peking University

Observations imply that long ＂y-ray bursts （GRBs） originate from the explo- sions of massive stars, therefore they may occur in the molecular clouds where their progenitors were born. We show that the prompt optical-UV emission from GRBs may be delayed due to dust extinction, which can explain the observed optical delayed on- set and fast rise in GRB 080319B well. The density and the size of the molecular cloud around GRB 080319B are roughly constrained to be ~ 103 cm-z and ~ 8 pc, respectively. We also investigate other GRBs with prompt optical-UV data, and find similar values of the densities and sizes of the local molecular clouds. Future obser- vations of prompt optical-UV emission from GRBs on a timescale of subseconds, e.g. by UFFO-Pathfinder and SVOM-GWAC, will provide more evidence and probes of the local environments of GRBs.
