NIDA Study Reveals Widespread Effects of Cocaine on Genome Structure and Function

Pin It

Repeated use of addictive drugs such as cocaine causes long-lasting changes in parts of the brain involved in motivation and reward, among others, yet the precise mechanisms by which these changes are maintained are poorly understood. A new study by scientists supported by the National Institute on Drug Abuse (NIDA), published May 14, 2009 in the journal Neuron, sheds light on this process by providing fundamental new insights into the effects of cocaine on the structure and function of the genome, the complete set of DNA instructions needed to make an organism. Scientists see vast clinical potential of these newly identified gene targets.

Flow of Potassium Into Cells Implicated in Schizophrenia—Blocking Errant Protein Could Stem Runaway Brain Activity in Psychosis

Pin It

A study on schizophrenia has implicated machinery that maintains the flow of potassium in cells and revealed a potential molecular target for new treatments. Expression of a previously unknown form of a key such potassium channel was found to be 2.5 fold higher than normal in the brain memory hub of people with the chronic mental illness and linked to a hotspot of genetic variation. An extensive series of experiments suggests that selectively inhibiting this suspect form could help correct disorganized brain activity in schizophrenia — without risk of cardiac side effects associated with some existing antipsychotic medications. Scientists at the National Institutes of Health and European colleagues report on threads of converging evidence in the May 2009 issue of the journal Nature Medicine.

  • Following is a link to the study write up on the British Cutlass study.  This study came out in 2006 shortly after the CATIE study funded by the US.  It also (as in the CATIE study) found that new antipsychotics were not any better at treating schizophrenia than old antipsychotics.  While the CATIE study got a lot of press here in the US the Cutlass study did not.  I happened across this link to the Cutlass study tonight and thought others might be interested in it.  I had not previously seen the actual write up on the Cutlass study.  It is interesting to note that the British researchers expected to see a significantly better outcome with new antipsychotics than old antipsychotics.
