Scientists identify schizophrenia's 'Rosetta Stone' gene

That is the title of this article I am writing about today. " Scientists have identified a critical function of what they believe to be schizophrenia's "Rosetta Stone" gene that could hold the key to decoding the function of all genes involved in the disease.

The breakthrough has revealed a vulnerable period in the early stages of the brain's development that researchers hope can be targeted for future efforts in reversing schizophrenia.
In a paper published in the journal Science, neuroscientists from Cardiff University describe having uncovered the previously unknown influence of a gene in ensuring healthy brain development.
The gene is known as 'disrupted in schizophrenia-1' (DISC-1). Past studies have shown that when mutated, the gene is a high risk factor for mental illness including schizophrenia, major clinical depression and bipolar disorder. The aim of this latest study was to determine whether DISC-1's interactions with other proteins, early on in the brain's development, had a bearing on the brain's ability to adapt its structure and function (also known as 'plasticity') later on in adulthood.
Many genes responsible for the creation of synaptic proteins have previously shown to be strongly linked to schizophrenia and other brain disorders, but until now the reasons have not been understood."It would be great if they can reverse schizophrenia and all mental illnesses.  I hope for the people who have not been diagnosed that they do not have to go through the same that I went through and all people who have this disease.
The article goes on to say: " Their experiments in mice revealed that by preventing DISC-1 from binding with these molecules -- using a protein-releasing drug called Tamoxifen at an early stage of the brain's development -- it would lack plasticity once it grows to its adult state, preventing cells (cortical neurons) in the brain's largest region from being able to form synapses.
The ability to form coherent thoughts and to properly perceive the world is damaged as a consequence of this.
Preventing DISC-1 from binding with 'Lis' and 'Nudel' molecules, when the brain was fully formed, showed no effect on its plasticity. However, the researchers were able to pinpoint a seven-day window early on in the brain's development -- one week after birth -- where failure to bind had an irreversible effect on the brain's plasticity later on in life.
'We believe that DISC-1 is schizophrenia's Rosetta Stone gene and could hold the master key to help us unlock our understanding of the role played by all risk genes involved in the disease,' said Professor Fox.
"The potential of what we now know about this gene is immense. We have identified a critical period during brain development that directs us to test whether other schizophrenia risk genes affecting different regions of the brain create their malfunction during their own critical period.
'The challenge ahead lies in finding a way of treating people during this critical period or in finding ways of reversing the problem during adulthood by returning plasticity to the brain. This, we hope, could one day help to prevent the manifestation or recurrence of schizophrenia symptoms altogether.'" It would be great if they can fix schizophrenia before it starts but it would be good also if they can just return the plasticity of the brain once people are diagnosed with a mental illness.
The article ends with: "Professor Jeremy Hall, an academic mental health clinician and director of Cardiff University's Neuroscience and Mental Health Research Institute, said:
"This paper provides strong experimental evidence that subtle changes early on in life can lead to much bigger effects in adulthood. This helps explain how early life events can increase the risk of adult mental health disorders like schizophrenia."
Schizophrenia affects around 1% of the global population and an estimated 635,000 people in the UK will at some stage in their lives be affected by the condition. The projected cost of schizophrenia to society is around £11.8 billion a year.
The symptoms of schizophrenia can be extremely disruptive, and have a large impact on a person's ability to carry out everyday tasks, such as going to work, maintaining relationships and caring for themselves or others."I do not have the problems that most with schizophrenia have. I have paranoid schizophrenia that did not start until age twenty eight I had all the symptoms but did not get fully diagnosed until age twenty nine.  So all I learned in those years stuck with me except math. I saw it as a chance to get out of a rotten life that all I was doing was always being locked up.  I will always wonder if being hit in the head with a barbell at age five had something to do with be ending up with this disease.  I know it was an accident but I will never know how my life could have turned out if I wasn't hit in the head.
