LncRNA SNHG3 is activated by E2F1 and promotes proliferation and migration of non‐small‐cell lung cancer cells through activating TGF‐β pathway and IL‐6/JAK2/STAT3 pathway

Jindong Shi, Jiannan Li, Shuang Yang, Xiaoying Hu, more

Journal of Cellular Physiology > 235 > 3 > 2891 - 2900

Recently, long noncoding RNAs (lncRNAs) have been widely reported to play pivotal roles in the regulation of human cancers. Although the oncogenic property of lncRNA small nucleolar RNA host gene 3 (SNHG3) has been revealed in a variety of cancers, functions and regulatory mechanism of SNHG3 in non‐small‐cell lung cancer (NSCLC) remain to be investigated. In this study, we detected the upregulated...

Ming Xu, Yanchao He, Kai Yu

IEEE Transactions on Aerospace and Electronic Systems > 2017 > 53 > 6 > 2950 - 2962

Based on currently developed on-board platforms, this paper proposes a software architecture for orbiting spacecraft for autonomously establishing formation, station-keeping, and reconfiguring maneuvers. Components of the software architecture include orbital prediction (OP), orbital control (OC), and relative navigation (RN); these not only meet the constraining requirements of attitude control,...

Respiratory Syncytial virus infection compromises asthma tolerance by recruiting interleukin-17A-producing cells via CCR6-CCL20 signaling

Tianyun Shi, Yanchao He, Wei Sun, Yi Wu, more

Molecular Immunology > 2017 > 88 > C > 45-57

Asthma tolerance can be induced by breast-feeding or oral feeding with ovalbumin (OVA). Anergy or deletion of specific T cells and generation of T regulatory cells might contribute to this process. However, whether respiratory syncytial virus (RSV) infection would affect asthma tolerance is not very clear. Here, we first established asthma and oral tolerance mouse models and then analyzed airway hypersensitivity...

Yanchao He, Yong Du, Sun Wei, Jindong Shi, more

The Clinical Respiratory Journal > 11 > 2 > 230 - 242

Background and Aims Genetic predisposition and environmental factors impact the development of lung cancer. The aim of this study was to investigate the association of single nucleotide polymorphisms (SNPs) of the IL‐17A and IL‐17F genes with lung cancer risk in Chinese Han population. Methods A total of 678 subjects were enrolled, including 320 lung cancer patients and 358 healthy controls. Six...

High-precision repeat-groundtrack orbit design and maintenance for Earth observation missions

Yanchao He, Ming Xu, Xianghua Jia, Roberto Armellin

Celestial Mechanics and Dynamical Astronomy > 2017 > 128 > 2-3 > 275-294

The focus of this paper is the design and station keeping of repeat-groundtrack orbits for Sun-synchronous satellites. A method to compute the semimajor axis of the orbit is presented together with a station-keeping strategy to compensate for the perturbation due to the atmospheric drag. The results show that the nodal period converges gradually with the increase of the order used in the zonal perturbations...

Yanchao He, Ming Xu

2016 12th World Congress on Intelligent Control and Automation (WCICA) > 804 - 808

2016 12th World Congress on Intelligent Control and Automation (WCICA)

The present paper proposes a formation configuration for three spacecrafts to perform the digital elevation model (abbr. DEM) for the distributed spacecraft interferometric synthetic aperture radar (InSAR). The configuration is optimized analytically to possess the best compatibility with J₂ relative invariant orbits. The relative orbital elements are utilized to design the optimal orbit by reducing...

FEBS Letters > 2014 > 588 > 17 > 3055-3061

The dysregulation of microRNAs (miRNAs) is crucially implicated in the development of various cancers. In this study, we explored the biological role of miR-141 in non-small cell lung cancer (NSCLC). miR-141 expression was significantly up-regulated in NSCLC tissues, and its overexpression accelerated NSCLC cell proliferation in vitro and tumor growth in vivo. We subsequently identified the antagonists...

In March 2013, a novel avian-origin influenza A (H7N9) virus was isolated from throat swabs of 2 patients at the Fifth People's Hospital of Shanghai, China. Subsequently, 4 more patients infected by H7N9 were identified. Of the 6 patients, 4 died of acute respiratory distress syndrome. Here, we report the first case of a patient who recovered from pneumonia induced by H7N9 infection. The patient presented...

A high-efficiency edge-preserving Bayesian method for image interpolation

Chuanbai Xiao, Yanchao He, Jing Yu

2008 9th International Conference on Signal Processing > 1042 - 1046

2008 9th International Conference on Signal Processing (ICSP 2008)

Common interpolation methods such as bilinear and bicubic tend to smooth edges in the interpolated image. We propose a high-efficiency edge-preserving Bayesian method for image interpolation. In the proposed method, the problem of image interpolation can be expressed as a constrained optimization problem, where two keys of solving speed are how to obtain search direction and step length. We find a...
