Fruit fly sheet on meth experience less drug toxicity if they ’ve been snacking on a sugary diet , a new study find oneself .
But this is n’t a spoonful - of - sugar - make - the - meth - go - down situation : Methamphetamine still damages the yield flies ' systems , said work investigator Barry Pittendrigh , a toxicologist at the University of Illinois . Besides , it ’s not yet known whether pelf in humans would provide a similar protective reaction , Pittendrigh told LiveScience .
Crystal meth
" We do know that masses who are methamphetamine addicts oftentimes take in expectant amounts ofsugary drinks , so that was an interesting observation , " Pittendrigh said . " But whether or not these things turn out to be relate is a question for succeeding inquiry . "
fly on meth
The haste that come with taking methamphetamines come up at a Leontyne Price . The drug can cause mental capacity changes lead to worked up and mental impairment , according to the National Institute on Drug Abuse . Meth ’s side effectsalso include extreme weightiness release , anxiety , mental confusion , insomnia , delusion and delusions .
All of thiswas experience from clinical studies , Pittendrigh said , but the molecular pathways that get these impression are less well sympathise . He and his colleagues turned to fruit flies as a modeling of what meth does to the body . Though far aside on the evolutionary ladder , yield fly sheet and humanity partake in many similarities on a molecular level , Pittendrigh say .
After some failed attempt to get the flies to take in ice , the investigator managed to abstract it into the louse ' food media . Then , they did genetic and molecular test to see how the meth affected fly biological science .
The impacts turned out to be very widespread . The investigator found 229 cistron that transcribe into protein other than under the influence of meth , and 34 changes in the molecular process that repulse cubicle . Meth picture altered the behavior of molecules affect in sugar metabolism , cellular muscularity contemporaries , and muscular tissue wellness , the research worker describe today ( April 20 ) in the open - access journalPLoS One . Even spermatogensis , or the ontogeny of spermatozoan , was shoot by meth ’s destructive power .
Meth also affectedoxidative stress , a aspect of cellular ageing . That finding was very logical , Pittendrigh said .
" Methamphetamines are know to cause a very rapid age effect , " he say . " Oxidative stress can induce a lot of damage to cell . "
sweetened protection
The finding that meth feign zip and metamorphosis made Pittendrigh and his colleagues marvel if clams metabolism ( how the body breaks down and employ sugar ) is n’t involved in meth ’s toxic personal effects . They fed meth - exposed fruit fly a dieting big in trehalose , an insect blood sugar , and establish that the sugar - corrode flies outlived those on a regular dieting .
Many of the event require stick with - up testing to find out their relevance to mammalian , Pittendrigh said . But the hope is that fruit fly can assist research worker understand what reach meth such a " horrifying molecule , " he said .
" Hopefully , some of these insights might lead to opportunities to deal with the problem connect with the drug , " he said .
