科研思路来自科研实践、来自文献信息、来自同行交流。

        科研思路和科研选题也可以来自知识发现,在我的博客“知识发现栏目”http://blog.sciencenet.cn/home.php?mod=space&uid=280034&do=blog&classid=115378&view=me&from=space有大量的科学研究知识发现的实例和分析,知识发现只提供非相关文献中的隐含知识概念,对于扩大科研人员的研究思路、进行科研选题很有意义,这些知识点可能对科研工作有所启发,获得新的科研视角和思路,但还需要科研人员进行科学验证。

科学家发现乳腺癌的生物标志物P27

       由哈佛干细胞研究所的Kornelia Polyak博士领衔的一个国际研究小组,解释了为什么二十出头就生育的女性为什么要比晚生育的女性,最终患上乳腺癌的几率小,这为解析乳腺癌致病机理,以及针对女性的癌症保护提出了新见解。 这一研究成果公布在Cell Stem Cell杂志上,并连续两个月入选了该期刊最受关注的文章。

       这一研究组成员历经20年收集了上千份女性组织样品,分析一种乳腺祖细胞标记:p27在这些样品中的变化情况,这20年时间可以说囊括了女性最重要的一个阶段。研究人员通过大量实验,希望能弄清楚p27是否是一种精确的乳腺癌预测标签,Polyak博士表示,如果这个假说被证实,那么未来几个月内,就可以开发出针对乳腺癌风险的临床诊断试剂。
