At present , homogeneous proteins of bsp proteins found in the sperm plasma of horse and pig have the binding - properties similar to bsp protein , which indicates that bsp protein and its homogeneous protein exist commonly in mammals and show their physiological functions 目前在猪及马的精浆中都发现了与bsp蛋白同源的蛋白质的存在，这些蛋白具有与bsp相似的结合特性，说明bsp蛋白及其同源蛋白在哺乳动物中是广泛存在的，并具有其生理意义。
Although history has witnessed fruitful achievement in the field of mammal apr , especially in the field of human clinical medicine , the fact that innate defense system plays more important role in the self - protection of lower animals thus they have robust apr system is worth much attention as well Apr的研究在哺乳动物中有较多的报道，研究成果多涉及人类医疗领域。低等生物在更大程度上倚赖apr的保护作用，例如鱼类就是一种很好的apr研究模型。
The results showed that the genes and amino acids of goat fsh - a and p subunits all have very high homology with other mammals and their homology all exceed 80 % . these results proved that fsh - a subunit has high conservation among mammals and fsh - p subunit is also quite conservative among mammals although it shows species specificity . goat fsh - a and p subunit genes were reamplified respectively by the new primers which had the corresponding restriction enzymes 结果显示山羊fsh - 、亚基基因及其各自对应的氨基酸与其他哺乳动物的同源性都非常高，一般均在80以上，验证了在同一种内，甚至在所有的哺乳动物中fsh -亚基是极为保守的；而fsh -亚基尽管具有种属特异性，但也是相当保守的。
Many researches were carried through in mammal animals showed that mitochondrial an er might have changed much after apoptosis induced by a variety of stimuli , including cytokines , anti - cancer drugs , growth factor deprivation and so on . however , few researches were gone on the apoptosis in the insect cells 在哺乳动物中的许多研究表明，各种诱导因素，如：抗癌药物、除去生长因子和细胞因子等引起凋亡时，线粒体和内质网中都会经历一系列的变化，而在昆虫细胞中这个方面的研究比较少。
