Common variants near ATM are associated with glycemic response to metformin in type 2 diabetes

Abstract: Metformin is the most commonly used pharmacological therapy for type 2 diabetes. We report a genome-wide association study for glycemic response to metformin in 1,024 Scottish individuals with type 2 diabetes with replication in two cohorts including 1,783 Scottish individuals and 1,113 individuals from the UK Prospective Diabetes Study. In a combined meta-analysis, we identified a SNP, rs11212617, associated with treatment success (n = 3,920, P = 2.9 P×-9, odds ratio = 1.35, 95% CI 1.22-1.49) at a locus containing ATM, the ataxia telangiectasia mutated gene. In a rat hepatoma cell line, inhibition of ATM with KU-55933 attenuated the phosphorylation and activation of AMP-activated protein kinase in response to metformin. We conclude that ATM, a gene known to be involved in DNA repair and cell cycle control, plays a role in the effect of metformin upstream of AMP-activated protein kinase, and variation in this gene alters glycemic response to metformin. © 2011 Nature America, Inc.

Learning Careers: Continuity and change in young people's dispositions to learning

Abstract: Despite an extensive literature on the subject of learning, very little has been written about the ways in which young people's dispositions to learning transform over time. This article draws upon a longitudinal research project which focused on such transformations. The article centres on the case of Amanda Ball and considers the implications which her story holds for our understanding of learning. It is shown that dispositions can transform in a short period of time and that such transformations are often linked, in complex ways, to wider social, economic and cultural contexts.

'French is the Language of Love and Stuff': Student perceptions of issues related to motivation in learning a foreign language

Abstract: This article reports on an investigation into the motivation of secondary school students in the South-west of England to learn foreign languages. A questionnaire was constructed based on a model derived from the motivation literature to examine students' responses on 16 constructs related to motivation. This was administered to 228 students in years 7, 8 and 9. The analysis revealed a decrease in motivation with age, and higher level of motivation among girls than boys. It also revealed a strikingly higher motivation to learn German than French, which was even more marked when the boys only were considered. These findings were further investigated using interviews. Both girls and boys were able to provide clear explanations for differences between the genders, as well as for the language differences. These included such aspects as French being considered feminine, it not being 'cool' for boys to be seen to make an effort at French, and the tendency for boys not to try at anything that appears to be tedious.
