GastrulationModels
Gastrulation has been celled "the most important time of your life" (Lewis Wolpert); without it you would be flat like a pancake! Vertebrate gastrulation is the process by which the simple structure of the blastula is transformed into the complex, 3-dimensional structure of the basic body plan by a series of cell shape changes and rearrangements. Due to basic differences in the construction of the early emb......阅读全文

（一）慢性支气管肺炎模型常选用大鼠、豚鼠或猴吸入刺激性气体（如二氧化硫、氯、氨水、烟雾等）复制人类慢性气管炎。现发现猪粘膜下腺体与人类相似，且经常发生气管炎及肺炎，故认为是复制人类慢性气管炎较合适的动物。用去甲肾上腺素可以引起与人类相似的气管腺体肥大。（二）肺气肿模型给兔等动物气管内或静脉内注射一定

徐国良院士Nature发表表观遗传学重要成果
表观遗传学修饰可以在不改变DNA序列的情况下调控基因的活性，而且这种修饰会受到环境因素的影响。DNA甲基转移酶（DNMT）介导的胞嘧啶甲基化是哺乳动物基因组最常见的一种表观遗传学修饰，在基因组印记、X染色体失活等重要过程中起到了关键性作用。TET家族的双加氧酶能够逐步氧化5-甲基胞嘧啶，由此实现

一字之差的论文标题，结论完全相反，到底该相信哪个？
其中2013年的文章的标题大意是说小鼠模型不能很好的模拟人类炎症性疾病，而2015年的论文则表示出完全相对的意思，即小鼠模型能够很好的模拟人类炎症性疾病（下图）。 众所周知，现代生物学研究中很重要的基石是大量运用小鼠模型来探索人类疾病的致病机理，很多初期的药物筛选都会用到大量的小鼠模型。201
