PTEN is a tumor suppressor gene. Recombinant PTEN is capable of dephosphorylating phosphatidylinositol 3,4,5-triphosphate[PI(3,4,5)P3], the product of phosphatidylinositol 3 -kinase. Many of the cancer-related mutations have been mapped to the phosphatase catalytic domain, it has been suggested that the phosphatase activity of PTEN is required for its tumor suppressor function. The activation of PKB/AKT is regulated ......阅读全文

引言血球计数板一直是实验室细胞计数的金牌标准。自从18世纪在法国第一次被用于分析病人的血液样本,血球计数板在过去几百年中已经得到一系列的重大发展,相比以前计数更为精确、使用更为简单,并最终形成了今天我们使用的样子。现在血球计数板计数仍然是所有细胞学研究的一个组成部分,然而其计数存在的问题由于自身固有
