BORN WITH IT Scientists Discover Possible 'Meth Gene’

Researchers have recently identified a gene that may play a role in meth addiction. New findings by Boston University School of Medicine researchers, published in PLOS Genetics, spotlight a gene called heterogeneous nuclear ribonucleoprotein H1 (Hn- rnph1). The research uncovered a link between this gene and how it effects behavior when stimulants are introduced. This new insight can help scientists understand genetic risk factors for addiction, along with some neuropsychiatric disorders. Also, this new understanding about how Hnrnph1 works could lead to the development of a prescription drug to help treat meth ad- diction, researchers say.

other findings to improve the treatment of both dopamine- related problems like attention- deficit hyperactivity disorder, schizophrenia, and bipolar disor- der, along with dopaminerelated neurodegenerative disorders like Parkinson’s or Huntington’s diseases. Scientists say the genetic epide- miology of meth use disorders is very complex. Efforts to under- stand the biological processes that increase susceptibility to meth use disorders (i.e., abuse, dependence and psychosis) have uncovered several genetic variants. However, more research needs to be done. Though gene research can led to breakthroughs in treatment, Boston University points out in its news release that genetics alone are not responsible for addiction. Environmental and social factors also play an im- portant role.

The BU scientists discovered that Hnrnph1 “codes” for an RNA protein that regulates how other genes are processed in the brain. To better understand the genetic basis of meth addiction, the next step is to figure out the exact genetic targets of Hnrnph1. “A better understanding of the brain region and cell type-specific binding targets of Hnrnph1 will tell us more about the function of this gene and possibly identify new therapeutic strategies for minimizing risk and treating psycho-stimulant addiction — a disorder for which there is currently no FDA-approved drug,” says study co-author Dr. Camron Bryant in a news release from Boston University.
