Mechanisms by which variants in the TCF7L2 gene increase the risk of developing Type 2 diabetes
Popular Abstract in Chinese 概括 II型糖尿病的發展趨勢在全世界範圍內非常迅速。我國目前有超過九千萬II型糖尿病患者,另外有大量血糖不正常的糖尿病高危人群。其中只有三成病人對自己的病情有所了解。II型糖尿病的病人與日俱增。 說到糖尿病,自然就會想到胰島素,以及血糖和胰島素的關系。胰島素是人體中非常重要的激素(荷爾蒙)。人體所需要的糖分主要是從食物中的澱粉類食物(米飯,面食)中來的,肉類也含有一部分的糖分。糖分從小腸吸收進入血液循環。胰島素的功能是讓身體細胞把血液中的糖分吸收進入細胞(比如肌肉細胞)加以使用,同時降低血液中的血糖成份。如果胰島素分泌不足,或者人體細胞對胰島素的敏感性降低會引起血糖升高,長期高血糖會損害血管和臟器的健康,最終導致糖尿病並發癥的發生。糖尿病並發癥是一種常見的慢性並發癥,後果相當嚴重,足部壞疽、腎功能衰竭、尿毒癥、視力模糊不清、失明、腦血Type 2 diabetes mellitus (T2DM) is a heterogeneous disease with a multifactorial aetiology comprising of genetic and environmental factors. The common variant most highly associated with T2DM known to date is a SNP rs7903146 in the TCF7L2 gene. However, the role TCF7L2 plays in the development of T2DM was unclear. Clinical, animal and in vitro studies have revealed an association of the risk T-all
