低氧诱导因子1α在骨关节炎软骨退变中作用的研究进展

The relationship between hypoxia-inducible factor-1α and cartilage degeneration in osteoarthritis: a review

骨关节炎是临床常见病、多发病,其重要始发因素及病理改变是软骨退变。软骨组织处于低氧微环境中,低氧诱导因子1α(hypoxia-inducible factor-1α,HIF-1α)是介导细胞低氧反应的核转录因子,是关节软骨适应低氧环境的一个关键性的调控因子。它对于关节软骨的形成、能量代谢、基质合成等具有重要作用,如果敲除此基因,软骨将不能维持正常形态及功能,导致软骨退变,产生骨关节炎等疾病。中药可以调节HIF-1α基因的表达,从而治疗骨关节炎。本文综述了近年来关于HIF-1α基因与骨关节炎软骨退变的相关性研究现状。

Osteoarthritis is one of the most common diseases seen in clinical practice. Cartilage survives in the hypoxic microenvironment. Hypoxia-inducible factor-1α （HIF-1α） is a key nuclear transcription factor which mediates the hypoxic response of cells. HIF-1α gene is an important regulator for the adaptation of articular cartilage to the hypoxic environment. It is important for formation of articular cartilage, energy metabolism and matrix synthesis. If the HIF-1α gene is knocked out, the cartilage can not maintain their normal morphology and function, which may lead to cartilage degeneration, and result in diseases such as osteoarthritis. Chinese herbal medicines can regulate the expression of HIF-1α gene and supply a therapy method for osteoarthritis. In this paper, the authors review the situation of the correlation between HIF-1α and osteoarthritis cartilage degeneration examined in recent years.
