-Caveat Lector- Study Probes Biological Clock Genes WASHINGTON (AP) - Genes that control the biological clock of fruit flies also affect whether those flies become addicted to cocaine, says a surprising new study that suggests these internal clocks - humans have them, too - might have still other undiscovered roles in the body. It's unclear what the cocaine discovery might mean for human drug addiction, although scientists have used fruit flies as potential models to study the biology behind drug abuse. The hope is that the insect studies ultimately will point the way toward better drug treatments. University of Virginia researchers studied the ``sensitization'' of fruit flies to cocaine, giving repeated doses to produce increasingly severe responses - in flies, problems with flying. The researchers report Friday in the journal Science that genes that control fruit flies' internal circadian rhythms also determined whether they become sensitized to cocaine. They found that normal fruit flies do become sensitized, but flies that lacked any of four genes that play a role in the flies' biological clocks did not become sensitized, despite repeated cocaine dosings. Those genes may regulate an enzyme that appears important in determining whether cocaine sensitization occurs, the researchers said.
