    Mouse Models of Inflammation Are Basically Worthless. Now We Know.

    We go through a lot of mice in this business. They’re generally the first animal that a potential drug runs up against: in almost every case, you dose mice to check pharmacokinetics (blood levels and duration), and many areas have key disease models that run in mice as well. That’s because we know a lot… Read More

    Lab Animals Wiped Out in Hurricane Sandy

    When I mentioned the people working in the research animal facilities before Hurricane Sandy, I had no idea that this was going to happen: thousands of genetically engineered and/or specially bred rodents were lost from an NYU facility due to flooding. The Fishell lab appears to have lost its entire stock of 2,500 mice, representing… Read More

    The Mouse Trap

    If you haven’t seen it, this series by Daniel Engber at Slate, on the use of the mouse as a laboratory workhorse, is excellent. (And I’m not just saying that because he references some of my disparaging comments about xenograft models, although that did give me a chance to teach my kids what the word… Read More

    Reboxetine Doesn’t Work. But That’s Not the Real Problem.

    Some time ago, I took nominations for Least Useful Animal Models. There were a number of good candidates, many of them from the CNS field. A recent report makes me think that these are even stronger contenders than I thought. The antidepressant reboxetine (not approved in the US, but sold in a number of other… Read More

    Cancer Cells: Too Unstable For Fine Targeting?

    The topic of new drugs for cancer has come up repeatedly around here – and naturally enough, considering how big a focus it is for the industry. Most forms of cancer are the very definition of “unmet medical need”, and the field has plenty of possible drug targets to address. But we’ve been addressing many… Read More

    Charles River Buys WuXi

    I don’t think we saw this one coming: Charles River Labs has announced that they’re buying WuXi PharmaTech. They’re paying about a 28% premium over Friday’s closing stock price – Charles River’s CEO will stay on, and WuXi’s founder (Li Ge) will serve as executive VP under him. Charles River, which is strong… Read More

    Animal Studies: Are Too Many Never Published At All?

    A new paper in PLoS Biology looks at animal model studies reported for the treatment of stroke. The authors use statistical techniques to try to estimate how many have gone unreported. From a database with 525 sources, covering 16 different attempted therapies (which together come to 1,359 experiments and 19,956 animals), they find that only… Read More

    Fat Rats Make Poor Test Subjects?

    Well, here’s a brow-furrowing paper, courtesy of PNAS. Th authors, from the National Institute on Aging, contend that most laboratory rodents are overfed, under-stimulated, and are (to use their phrase) “metabolically morbid”. This affects their suitability as control and experimental animals for a wide variety of assays. There se… Read More

    Animal Testing: A View From the Labs

    Why do we test drugs on animals, anyway? This question showed up in the comments section from a lay reader. It’s definitely a fair thing to ask, and you’d expect that we in the business would have a good answer. So here it is: because for all we know about biochemistry, about physiology and about… Read More

    Animal Rights, You Say?

    Novartis has had trouble for years with animal rights activists, and now things are getting nastier than ever: Novartis CEO Daniel Vasella says the people who burned down his holiday home and defiled his family’s graves are not criminals but “terrorists” beyond dialogue. In an interview with the SonntagsBlick newspaper, the 55-yea… Read More
