HSP27和HSP70mRNA在大肠癌中表达的临床意义

目的:探讨HSP27和HSP70 mRNA在大肠癌中表达的临床意义。方法:取大肠癌标本77例,采用免疫组织化学方法检测HSP27的表达状况,从中选取36例手术标本,采用核酸原位杂交技术(ISH)检测HSP70 mRNA的表达。结果:HSP27和HSP70 mRNA在大肠癌中的阳性率分别为40.3%和66.9%,HSP27和HSP70 mRNA均与大肠癌的分化程度相关,与发生部位、浸润深度及淋巴结转移无明显相关性。结论:检测HSP27和HSP70 mRNA可作为大肠癌患者预后的一个重要指标。     

New Technique Developed to Identify Clusters of Proteins on the Plasma Membrane of Immune Cells

<正>When our bodies are under attack from foreign organisms,such as bacteria and viruses,our immune system orchestrates a complex fight-back involving many separate parts.One important component of this response is a type of cell called the B-lymphocyte–it is this cell that is at the forefront of our
