MicroRNAs Help Control HIV Life Cycle
Scientists at Burnham Institute for Medical Research (Burnham) have discovered that specific microRNAs (non-coding RNAs that interfere with gene expression) reduce HIV replication and infectivity in human T-cells. In particular, miR29 plays a key role in controlling the HIV life cycle. The study suggests that HIV may have co-opted this cellular defense mechanism to help the virus hide from the immune system and antiviral drugs. The research was published today in the journal Molecular Cell.

Schizophrenia And Bipolar Disorder Share Genetic Roots
A trio of genome-wide studies - collectively the largest to date - has pinpointed a vast array of genetic variation that cumulatively may account for at least one third of the genetic risk for schizophrenia. One of the studies traced schizophrenia and bipolar disorder, in part, to the same chromosomal neighborhoods.

Combined Data From Four Large-Scale Studies Demonstrate The Efficacy And Tolerability Of Seroquel In Bipolar Depression

Results presented today at the 162nd American Psychiatric Association (APA) congress in San Francisco, CA, demonstrated the efficacy and tolerability of SEROQUEL® (quetiapine fumarate) for treating depressive episodes in bipolar disorder, including the difficult-to-treat bipolar II patient population.1,2 The data are from combined analyses of four large-scale clinical trials to examine SEROQUEL as a treatment for depressive episodes associated with bipolar I and II disorders. SEROQUEL and SEROQUEL XR™, a once-daily, extended-release formulation of SEROQUEL, is one of the most widely studied atypical antipsychotic in bipolar depression and the only agent approved as monotherapy to treat the spectrum of mood episodes associated with bipolar disorder. "Bipolar disorder is a chronic illness with patients experiencing severe debilitating mood swings. Patients spend a majority of their time ill in the depressed phase of the illness. These important findings confirm that SEROQUEL is an effective agent for the treatment of bipolar depression, and particularly encouraging are the results in bipolar II patients who historically have not responded well to treatment," said Professor Alan Young of the Department of Psychiatry, University of British Columbia, Vancouver, Canada. Results from a combined analysis of all patients with bipolar I or II disorder (n=2593) demonstrated that SEROQUEL monotherapy was significantly more effective than placebo for treating depressive episodes associated with bipolar disorder as measured by improvements in the Montgomery-ãºsberg Depression Rating Scale (MADRS) total score (PAbout SEROQUEL and SEROQUEL XR Launched in 1997, it is estimated that SEROQUEL has been prescribed to more than 22 million patients worldwide. SEROQUEL has been approved in 94 countries for schizophrenia, 92 countries for bipolar mania, in 41 countries for bipolar depression and in 6 countries for bipolar maintenance. SEROQUEL XR has been approved in 53 countries for schizophrenia, 19 countries for bipolar mania, in 20 countries for bipolar depression, in 9 markets for bipolar maintenance, in 1 market for Major Depressive Disorder (MDD), and in 1 market for Generalised Anxiety Disorder (GAD).
