To evaluate the role of apoptosis in the pathogenesis of brain lesions in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a hereditary microangiopathy leading to cognitive decline and dementia, caused by mutations in the NOTCH3 gene. Detection of apoptotic nuclei in temporal lobe, brain stem, medulla oblongata, hippocampus and basal ganglia from one young CADASIL patient was performed by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end-labeling (TUNEL). Our results showed a great involvement of glial cells in apoptotic cell death in the majority of the brain regions examined; neuronal apoptosis was significantly present only in the brain stem region. We hypothesized that in the early stages of the disease neuronal involvement of apoptosis is limited to the cells of the brain stem, sparing the cortical area which is involved in neuronal apoptosis and cognitive decline later.
Which gene is involved in CADASIL?

Children who see their parents drunk are twice likely to get drunk themselves, a survey of young teenagers has suggested. Poor parental supervision also raises the chances of teenage drinking, said the Joesph Rowntree Foundation. If parents don't know where their children are on a Saturday night, or let them watch films of violence, they are more likely to have had an alcoholic drink. The survey also found the behavior of friends is also a powerful factor in drinking habits. The more time teenagers spend with friends, the more likely they are to drink alcohol. In this survey of 5,700 children aged 13 to 16, carried out by the Joseph Rowntree Foundation, researchers found that one in five wanted to have a drink by the time they were 14. By the age of 16, half of those questioned said they had been drunk. Pamela Bremner, scientist of the survey, said, "For the first time in the UK, this study shows what most influences young people's drinking behavior." "It found that the behavior of friends and family is the most common influential factor in determining how likely and how often a young person will drink alcohol." Don Shenker, Chief Executive of Alcohol Concern, said, "Government ministers must also look at some of the causes of why it is so easy for children to get alcohol, usually from the home." "Governments should look to see if they've done everything they can to help the large supermarkets from continuing to sell cheap alcohol which encourages more alcohol sales and therefore results in more alcohol being stored in the home." The Royal College of Physicians also said it was not surprising that being able to get alcohol easily was an important factor on current drinking problems and drunkenness of teenagers. A statement said, "This shows that the government needs to focus more attention on increasing the price of alcohol, and increasing education and national campaigns for both young people and their families on the dangers of alcohol."

Who should be responsible for the fact that some teenagers formed the habit of drinking besides their parents and friends, according to Don Shenker?
