在一项新的研究中，来自美国德州大学MD安德森癌症中心的研究人员利用患者源性肿瘤异种移植（patient—derived tumorxenograft,PDx）和模式小鼠开展一系列临床前实验，鉴定出一种门卫蛋白（gatekee Perprotein）阻止胰腺癌细胞转化为一种极具侵袭性的细胞类型，并且也发现剔除这种门卫蛋白的疗法能够阻止这些癌细胞。这些发现有助为携带这种进展迅速的治疗抵抗性的胰腺癌细胞亚群的患者开发出潜在的疗法。

Ltd.

The China Seismo-Electromagnetic Satellite(CSES) mission was proposed in 2003 and approved in 2013 after ten years' scientific and engineering demonstrations. To meet the requirement of scientific objectives, the satellite is designed to be in a sunsynchronous orbit with an altitude of 507 km and descending node time of 14:00 LT. The CSES satellite carries 8 instruments,including search-coil magnetometer(SCM), electric field detector(EFD), high precision magnetometer(HPM), GNSS occultation receiver(GOR), plasma analyzer package(PAP), langmuir probe(LAP), high energetic particle package(HEPP) and detector(HEPD), and tri-band beacon(TBB), among which HEPD is provided by Italian Space Agency. The CSES satellite was launched successfully on February 2, 2018, and is planned to operate for 5 years. The CSES mission is the first satellite in China to measure geophysical fields, which will have a lot of application prospects in the study of seismology, geophysics, space sciences, and so on.
