The key difference in this study was the presence of a single gene from the H3N2 human virus: the PB2 protein, which gave the hybrid viruses the ability to spread easily among the lab mice.

这项研究中一个关键的不同点就是H3N2人类流感病毒中存在一个蛋白基因：PB2蛋白，它的存在使得杂交病毒具有了在实验小鼠之间轻易传染的能力。

Also, the lab was able to read only part of my APOE gene, so it's impossible to say much about my risk for Alzheimer's.

另外，实验室只能读取我的部分APOE基因，所以并不能判断我患阿尔兹·海默症的风险。

A 2004 McGill University study of lab rats found that certain maternal behaviors can silence a gene in the hippocampi of their pups, leaving them less able to handle stress hormones.

2004年麦吉尔大学的大鼠试验发现母鼠的某些特定行为使幼鼠大脑海马区的某些基因沉默，小鼠处理应激激素的能力因而下降。

Engineered in lab mice, this gene produced a protein (named OPG) that vastly increased bone strength and thickness-without causing any harmful side effects.

FORBES: Biotech Behemoth

The biggest reward of Amgen's early genome work, however, may be the osteoporosis drug dubbed AMG 162, based on the bone gene that Amgen lab coats were so surprised to discover in fetal rat intestines in 1995.

FORBES: Companies, People, Ideas

Patsalis of the Cyprus Institute of Neurology and Genetics said his team is developing a noninvasive method to test for Down syndrome by comparing fetal DNA to the mother's using standard lab equipment, instead of pricey gene-sequencing gear.
