question:
1. In order to investigate the biological function of the human CLN3 gene that is defective in Batten disease, we created a yeast strain by PCR-targeted disruption of the yeast gene (YHC3), which is a homologue of the human CLN3 gene. 2. The phenotypic characterization revealed that the yhc3 delta mutants are more sensitive to combined heat and alkaline stress than the wild-type strains as determined by inhibition of cell proliferation. 3. This suggests that the yhc3 delta mutant is a good model to investigate the biological function of human CLN3 gene in mammalian cells and to understand the pathophysiology of juvenile Batten disease.
answer:
What is the effect of a defective CLN3 gene?


question:
"We don't necessarily believe that new advertising, which might make consumers feel better about the Coke brand or better about the ads themselves , will actually result in consumers consuming more of the product," Morgan Stanley's Bill Pecoriello wrote in a research note the days after the investor meeting . But Coke is optimistic it can regain its old magic, and is banking on a new slogan: "Welcome to the Coke side of life." BREAK THROUGH HIT? With PepsiCo about to surpass Coke as the beverage king on Wall Street--Pepsi's market capitalization has _ in recent years to $97.9 billion, putting it less than a billion dollars behind its rival--the heat is on Coke . It's set to launch a new marketing campaign in March, 2006. And having taken a quick look at Coke's investor presentation on Dec. 7 in New York, my sense is that Coke may be moving in the right direction . Given the continued shift by consumers away from soda--Coke's stronghold --and into alternative beverages like juice, tea, and water, Coke badly needs a breakthrough hit. And given that shift away from soda, some analyists wonder whether even the catchiest new ads will be enough to put the fizz back into Coke. SAME OLD, UPDATED? The new flavors of PowerAde sports drink will probably enable Coke to continue stealing market share from PepsiCo's Gatorade brand. And Coke is getting a little more creative with packaging, including new, aluminum bottles of Coke that will be sold in nightclubs, and an 8.4-ounce "100 calorie" version of its flagship Coke that will appeal to women who want fewer calories and will like the fact that the small can will fit in their purse. I doubt whether other new products will be successful, including a new coffee-flavored soda called Coke-Cola Black that I tried. Think carbonated coffee. But I'm not sure if the product, which Coke is pitching as an afternoon pick-me-up for the 35-and-over set, is going to pull people away from their afternoon Frappucino fix. And my opinion is that Vault, an orange-flavored energy drink, will have just as much trouble unseating Mountain Dew among teens as did Coke's last attempt, a product called Surge. If there is one concern I have about the fresh offerings Coke plans to launch this year, it appears that many of them are simply new brands, not new products.
