As we recover from the holiday weekend, there’s some intoxicating1 news on curbing2 the effects of alcohol. In the May 29th issue of Cell, scientists report discovering a gene3 that controls fruit flies’ sensitivity to ethanol. And if that just sounds like tipsytalk, the finding suggests that a couple of current anticancer drugs might find use in treating alcoholism.

Some flies, like some people, just can’t hold their drink. One sip4 and they’re tripping over their own wings. So the scientists set out to search for the fly genes5 involved in alcohol sensitivity. And they turned up a gene they call happyhour. Flies with a normal version of this gene are liquor light-weights, while happyhour mutants can drink their fly friends under the table.

In the normal flies, happyhour blocks a hormone6 called EGF. And the scientists found that two anticancer drugs, which also inhibit7 EGF, make boozing flies more woozy—a feeling that’s as unpleasant for flies as it is for people. Rats, too, will take a nip and say enough when they’re on these drugs.

Robbing booze of its buzz is one way to attack alcoholism. Which means that, at least genetically8 speaking, it’s good to have a little happyhour.
